  • Safety and Efficacy Study of an Anti-CD20 Monoclonal Antibody (AME-133v) to Treat Non-Hodgkin's Lymphoma Not Recruiting

    The protein engineering of AME-133v is hypothesized to result in an anti-CD20 therapy with greater potency and efficacy in all patients, but particularly in genetically defined subpopulations that respond poorly to rituximab because they express a low affinity version of the Fc receptor on their immune effector cells. A monoclonal antibody that has increased binding for this receptor should be more effective in stimulating effector cell killing and thus improve response to the antibody. This study is designed to provide evidence of the safety and a preliminary understanding of the efficacy of AME 133v.

  • A multicenter phase II study of pazopanib in patients with advanced gastrointestinal stromal tumors (GIST) following failure of at least imatinib and sunitinib. Annals of oncology Ganjoo, K. N., Villalobos, V. M., Kamaya, A., Fisher, G. A., Butrynski, J. E., Morgan, J. A., Wagner, A. J., D'adamo, D., McMillan, A., Demetri, G. D., George, S. 2014; 25 (1): 236-240

    Abstract

    Advanced GISTs are incurable, but often treatable for years with tyrosine kinase inhibitors (TKIs). The majority of GISTs harbor an oncogenic activating mutation in KIT or PDGFRA. Inhibition of this activating mutation with TKIs most often leads to durable disease control for many patients. However, almost all patients develop resistance to these TKIs, typically due to the development of secondary mutations, heralding the need for new therapeutic options. We conducted a phase II study evaluating the efficacy and toxicity of pazopanib, a broad spectrum TKI inhibiting KIT, VEGFRs (-1, -2, and -3), and PDGFR (-α and-β) in patients with advanced GIST following failure of at least imatinib and sunitinib.Patients received pazopanib 800 mg orally once daily. All patients were assessed for efficacy with CT scans every 8 weeks (two cycles). Patients continued pazopanib until progression or unacceptable toxicity. The primary end point was the 24-week nonprogression [complete response+partial response+stable disease (SD)] rate (NPR) per RECIST 1.1. Secondary end points included PFS, OS, and toxicity.Between August 2011 and September 2012, a total of 25 patients were treated at two institutions. Median number of prior therapy was 3 (range 2-7). A total of 90 cycles of pazopanib were administered, with a median of two cycles (range 1 to 17+) per patient. Best response of SD at any time was observed in 12 (48%) patients. The NPR was 17% [95% confidence interval (CI) 4.5-37]. All but one patient discontinued protocol either due to PD (n = 19) or intolerance (n = 4). One patient with succinate dehydrogenase (SDH)-deficient GIST exhibited continuing disease control after 17 cycles. The median PFS for the entire cohort was 1.9 months (95% CI 1.6-5.2), and the median OS was 10.7 months (95% CI 3.9-NR).Pazopanib was reasonably well tolerated with no unexpected toxicities. Pazopanib as a single agent has marginal activity in unselected heavily pretreated patients with advanced GIST.

  • The Treatment Outcome for Adult Patients with Ewing's Sarcoma. Current oncology reports Ganjoo, K. N., Patel, S. 2013; 15 (4): 372-377

    Abstract

    Ewing's sarcoma is the second most common bone malignancy in children, but is extremely rare in adults. The outcome of patients with localized disease has improved over the past decades due to better combination chemotherapies, and better methods of local control. Unfortunately, patients with metastatic disease have a very poor outcome with current antineoplastic therapies. In this article, we will review the primary treatment for adult patients with Ewing's sarcoma, both for localized and metastatic disease. The prognostic factors in adult patients with EWS will also be reviewed.

  • Chest Wall Leiomyosarcoma After Breast-Conservative Therapy for Early-Stage Breast Cancer in a Young Woman With Li-Fraumeni Syndrome JOURNAL OF THE NATIONAL COMPREHENSIVE CANCER NETWORK Henry, E., Villalobos, V., Million, L., Jensen, K. C., West, R., Ganjoo, K., Lebensohn, A., Ford, J. M., Telli, M. L. 2012; 10 (8): 939-942

    Abstract

    Li-Fraumeni syndrome (LFS) is one of the most penetrant forms of familial cancer susceptibility syndromes, characterized by early age at tumor onset and a wide spectrum of malignant tumors. Identifying LFS in patients with cancer is clinically imperative because they have an increased sensitivity to ionizing radiation and are more likely to develop radiation-induced secondary malignancies. This case report describes a young woman whose initial presentation of LFS was early-onset breast cancer and whose treatment of this primary malignancy with breast conservation likely resulted in a secondary malignancy arising in her radiation field. As seen in this case, most breast cancers in patients with LFS exhibit a triple-positive phenotype (estrogen receptor-positive/progesterone receptor-positive/HER2-positive). Although this patient met classic LFS criteria based on age and personal and family history of cancer, the NCCN Clinical Practice Guidelines in Oncology for Genetic/Familial High-Risk Assessment: Breast and Ovarian Cancer endorse genetic screening for TP53 mutations in a subset of patients with early-onset breast cancer, even in the absence of a suggestive family history, because of the potential for de novo TP53 mutations.

    Abstract

    The major changes to the 2012 and 2011 NCCN Guidelines for Soft Tissue Sarcoma pertain to the management of patients with gastrointestinal stromal tumors (GISTs) and desmoid tumors (aggressive fibromatosis). Postoperative imatinib following complete resection for primary GIST with no preoperative imatinib is now included as a category 1 recommendation for patients with intermediate or high risk of recurrence. The panel also reaffirmed the recommendation for preoperative use of imatinib in patients with GISTs that are resectable with negative margins but associated with significant surgical morbidity. Observation was included as an option for patients with resectable desmoid tumors that are small and asymptomatic, not causing morbidity, pain, or functional limitation. Sorafenib is included as an option for systemic therapy for patients with desmoid tumors.

    Abstract

    We retrospectively analyzed hematologic parameters in 22 patients with advanced, nonsquamous, NSCLC undergoing VEGF inhibition on a phase II clinical trial of bevacizumab, carboplatin, and gemcitabine. We also examined TTP in relation to hemoglobin changes. Median hemoglobin increased significantly from a 12.9 g/dL pretreatment to 13.8 g/dL (p =.01) after the second cycle of maintenance bevacizumab until the first off cycle measurement. There was no difference in TTP in patients who achieved a rise in hemoglobin compared with patients who did not (median 238 days vs. 268 days, p =.38.) Maintenance bevacizumab is associated with increased hemoglobin in advanced, nonsquamous, NSCLC patients.

  • Results of a Phase 1 Study of AME-133v (LY2469298), an Fc-Engineered Humanized Monoclonal Anti-CD20 Antibody, in Fc gamma RIIIa-Genotyped Patients with Previously Treated Follicular Lymphoma CLINICAL CANCER RESEARCH Forero-Torres, A., de Vos, S., Pohlman, B. L., Pashkevich, M., Cronier, D. M., Dang, N. H., Carpenter, S. P., Allan, B. W., Nelson, J. G., Slapak, C. A., Smith, M. R., Link, B. K., Wooldridge, J. E., Ganjoo, K. N. 2012; 18 (5): 1395-1403

    Abstract

    AME-133v is a humanized monoclonal antibody engineered to have increased affinity to CD20 and mediate antibody-dependent cell-mediated cytotoxicity (ADCC) better than rituximab. Safety, pharmacokinetics, and efficacy were assessed in a phase 1/2 trial in patients with previously treated follicular lymphoma (FL).AME-133v was characterized in vitro by ADCC and cell binding assays. A phase 1 study was conducted in which 23 previously treated patients with FL were assigned sequentially to one of five dose-escalation cohorts of AME-133v at 2, 7.5, 30, 100, or 375 mg/m(2) weekly × 4 doses.AME-133v showed a 13- to 20-fold greater binding affinity for CD20 and was 5- to 7-fold more potent than rituximab in ADCC assays. Cell binding assays showed AME-133v and rituximab competed for an overlapping epitope on the CD20 antigen, and AME-133v inhibited binding of biotinylated rituximab to CD20 in a concentration-dependent manner. AME-133v was well tolerated by patients and common related adverse events included chills and fatigue. One patient experienced a dose-limiting toxicity of neutropenia. AME-133v showed nonlinear pharmocokinetics with properties similar to rituximab. Selective reduction of B cells during and after AME-133v treatment was shown by flow cytometry of peripheral blood. A partial or complete response was observed in 5 of 23 (22%) patients and the median progression-free survival was 25.4 weeks.AME-133v was safe and well tolerated at the doses tested. AME-133v showed encouraging results as an anti-CD20 therapy in heavily pretreated FL patients with the less favorable Fc?RIIIa F-carrier genotype.

  • R1507, a Monoclonal Antibody to the Insulin-Like Growth Factor 1 Receptor, in Patients With Recurrent or Refractory Ewing Sarcoma Family of Tumors: Results of a Phase II Sarcoma Alliance for Research Through Collaboration Study JOURNAL OF CLINICAL ONCOLOGY Pappo, A. S., Patel, S. R., Crowley, J., Reinke, D. K., Kuenkele, K., Chawla, S. P., Toner, G. C., Maki, R. G., Meyers, P. A., Chugh, R., Ganjoo, K. N., Schuetze, S. M., Juergens, H., Leahy, M. G., Geoerger, B., Benjamin, R. S., Helman, L. J., Baker, L. H. 2011; 29 (34): 4541-4547

    Abstract

    The type 1 insulin-like growth factor 1 receptor (IGF-1R) has been implicated in the pathogenesis of the Ewing sarcoma family of tumors (ESFT). We conducted a multicenter phase II study of the fully human IGF-1R monoclonal antibody R1507 in patients with recurrent or refractory ESFT.Patients ? 2 years of age with refractory or recurrent ESFT received R1507 at doses of 9 mg/kg intravenously one a week or 27 mg/kg intravenously every three weeks. Response was measured by using WHO criteria. Tumor imaging was performed every 6 weeks for 24 weeks and then every 12 weeks.From December 2007 through April 2010, 115 eligible patients from 31 different institutions were enrolled. The median age was 25 years (range, 8 to 78 years). The location of the primary tumor was bone in 57% of patients and extraskeletal in 43% of patients. A total of 109 patients were treated with R1507 9 mg/kg/wk, and six patients were treated with 27 mg/kg/3 wk. The overall complete response/partial response rate was 10% (95% CI, 4.9% to 16.5%). The median duration of response was 29 weeks (range, 12 to 94 weeks), and the median overall survival was 7.6 months (95% CI, 6 to 9.7 months). Ten of 11 responses were observed in patients who presented with primary bone tumors (P = .016). The most common adverse events of grades 3 to 4 were pain (15%), anemia (8%), thrombocytopenia (7%), and asthenia (5%).R1507 was a well-tolerated agent that had meaningful and durable benefit in a subgroup of patients with ESFT. The identification of markers that are predictive of a benefit is necessary to fully capitalize on this approach.

  • The Prognostic Value of Tumor-Associated Macrophages in Leiomyosarcoma A Single Institution Study AMERICAN JOURNAL OF CLINICAL ONCOLOGY-CANCER CLINICAL TRIALS Ganjoo, K. N., Witten, D., Patel, M., Espinosa, I., La, T., Tibshirani, R., van de Rijn, M., Jacobs, C., West, R. B. 2011; 34 (1): 82-86

    Abstract

    High numbers of tumor-associated macrophages (TAMs) have been associated with poor outcome in several solid tumors. In 2 previous studies, we showed that colony stimulating factor-1 (CSF1) is secreted by leiomyosarcoma (LMS) and that the increase in macrophages and CSF1 associated proteins are markers for poor prognosis in both gynecologic and nongynecologic LMS in a multicentered study. The purpose of this study is to evaluate the outcome of patients with LMS from a single institution according to the number of TAMs evaluated through 3 CSF1 associated proteins.Patients with LMS treated at Stanford University with adequate archived tissue and clinical data were eligible for this retrospective study. Data from chart reviews included tumor site, size, grade, stage, treatment, and disease status at the time of last follow-up. The 3 CSF1 associated proteins (CD163, CD16, and cathepsin L) were evaluated by immunohistochemistry on tissue microarrays. Kaplan-Meier survival curves and univariate Cox proportional hazards models were fit to assess the association of clinical predictors as well as CSF1 associated proteins with overall survival.A total of 52 patients diagnosed from 1983 to 2007 were evaluated. Univariate Cox proportional hazards models were fit to assess the significance of grade, size, stage, and the 3 CSF1 associated proteins in predicting OS. Grade, size, and stage were not significantly associated with survival in the full patient cohort, but grade and stage were significant predictors of survival in the gynecologic (GYN) LMS samples (P = 0.038 and P = 0.0164, respectively). Increased cathepsin L was associated with a worse outcome in GYN LMS (P = 0.049). Similar findings were seen with CD16 (P < 0.0001). In addition, CSF1 response enriched (all 3 stains positive) GYN LMS had a poor overall survival when compared with CSF1 response poor tumors (P = 0.001). These results were not seen in non-GYN LMS.Our data form an independent confirmation of the prognostic significance of TAMs and the CSF1 associated proteins in LMS. More aggressive or targeted therapies could be considered in the subset of LMS patients that highly express these markers.

  • Current and Emerging Pharmacological Treatments for Gastrointestinal Stromal Tumour DRUGS Ganjoo, K. N., Patel, S. 2011; 71 (3): 321-330

    Abstract

    Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the gastrointestinal tract, previously classified as leiomyosarcomas. Most GIST express KIT and the majority have mutations in the KIT gene. The most common KIT mutation occurs in the juxtamembrane domain of exon 11. These mutations lead to cellular proliferation and survival. GIST with exon 11 mutations respond better to tyrosine kinase inhibitors (TKIs) than those with exon 9 mutations. Most KIT-negative GIST express platelet-derived growth factor receptor (PDGFR)-?; however, a small percentage of GIST are negative for both KIT and PDGFR?. Imatinib and other TKIs have dramatically improved the outcome of patients with metastatic GIST. Newer and more advanced TKIs are under intense investigation as eventually all GIST patients develop resistant tumours. In addition, these drugs can be utilized in the preoperative setting for patients with unresectable localized tumours or those at high risk for surgical morbidity. TKIs have been given in the adjuvant setting for patients with resected tumours at high risk for recurrence. The duration of adjuvant therapy is currently under evaluation; however, it is possible that these patients would need to continue therapy indefinitely.

  • A Phase I Study of the Safety and Pharmacokinetics of the Hypoxia-Activated Prodrug TH-302 in Combination with Doxorubicin in Patients with Advanced Soft Tissue Sarcoma ONCOLOGY Ganjoo, K. N., Cranmer, L. D., Butrynski, J. E., Rushing, D., Adkins, D., Okuno, S. H., Lorente, G., Kroll, S., Langmuir, V. K., Chawla, S. P. 2011; 80 (1-2): 50-56

    Abstract

    The purpose of this study was to determine the dose-limiting toxicities (DLT), maximum tolerated dose (MTD), safety, pharmacokinetics and preliminary activity of TH-302, a hypoxia-activated prodrug, in combination with doxorubicin in patients with advanced soft tissue sarcoma. Patients andTH-302 was administered intravenously on days 1 and 8 and doxorubicin 75 mg/m² on day 1 (2 h after TH-302) of every 3-week cycle. TH-302 starting dose was 240 mg/m² with a classic 3 + 3 dose escalation. Pharmacokinetics were assessed on days 1 and 8 of cycle 1. Tumor assessments were performed after every second cycle.Sixteen patients enrolled. Prophylactic growth factor support was added due to grade 4 neutropenia. The MTD was 300 mg/m². DLTs at 340 mg/m² were neutropenia-associated infection and grade 4 thrombocytopenia. Common adverse events included fatigue, nausea and skin rash. There was no evidence of pharmacokinetic interaction between TH-302 and doxorubicin. Five of 15 (33%) evaluable patients had a partial response by RECIST (Response Evaluation Criteria in Solid Tumors) criteria.The hematologic toxicity of doxorubicin is increased when combined with TH-302. This can be mitigated by prophylactic growth factor support. Toxicities were manageable and there was evidence of antitumor activity.

  • A Phase II First-Line Study of Gemcitabine, Carboplatin, and Bevacizumab in Advanced Stage Nonsquamous Non-small Cell Lung Cancer JOURNAL OF THORACIC ONCOLOGY Clement-Duchene, C., Krupitskaya, Y., Ganjoo, K., Lavori, P., McMillan, A., Kumar, A., Zhao, G., Padda, S., Zhou, L., San Pedro-Salcedo, M., Colevas, A. D., Wakelee, H. A. 2010; 5 (11): 1821-1825

    Abstract

    Bevacizumab improves responses and progression-free survival when added to first-line paclitaxel/carboplatin or cisplatin/gemcitabine for patients with advanced nonsquamous non-small cell lung cancer. This study was designed to evaluate toxicities and efficacy of gemcitabine/carboplatin/bevacizumab.Patients with untreated advanced nonsquamous non-small cell lung cancer, with no evidence of brain metastases and not on anticoagulation were eligible. Patients received gemcitabine 1000 mg/m on days 1 and 8; carboplatin area under the curve 5 day 1; and bevacizumab 15 mg/kg day 1 every 3 weeks for up to six cycles. Bevacizumab was then continued every 3 weeks until disease progression or unacceptable toxicity.From July 2006 to December 2008, 48 patients were enrolled: 23 (48%) men, 25 (52%) women, and 19 (40%) never smokers. One patient never received therapy and is not included in the analysis. Median cycle number was 8 (1-42) with 37 patients (78.7%) completing ?4 cycles of three drugs. Dose reductions occurred in 34 (72.3%) patients. Grade 3/4 toxicities included neutropenia (47%/15%), thrombocytopenia (11%/15%), anemia (6%/0%), dyspnea (6%/2%), bacterial pneumonia (4%/0%), and hypertension (4%/2%). No neutropenic fevers occurred. One patient died of hemoptysis. Grade 3 bleeding occurred in three other patients. There were seven (14.9%) partial responses. Median time to first event (progression/death/toxicity requiring discontinuation) was 6.4 months (95% confidence interval: 4.8-7.9 months). The median overall survival (OS) was 12.8 months (95% confidence interval: 10.0-16.5). The OS is 57% at 1 year and 10% at 2 years.Although perhaps skewed by a high proportion of nonsmokers and women, treatment with gemcitabine/carboplatin/bevacizumab has an acceptable toxicity profile with promising median OS despite a low response rate.

  • New Developments in Targeted Therapy for Soft Tissue Sarcoma CURRENT ONCOLOGY REPORTS Ganjoo, K. N. 2010; 12 (4): 261-265

    Abstract

    Soft tissue sarcomas (STS) are rare diseases, with an estimated 10,390 new cases in the United States in 2008. Unfortunately, only 50% are cured with surgical resection. The standard cytotoxic chemotherapeutic agents have not been successful in the treatment of metastatic disease. The standard single-agent chemotherapy for metastatic disease is doxorubicin, with only 20% to 25% response rates. The combination of doxorubicin with other agents, such as ifosfamide, has improved response rates, without any improvement in overall survival. New targeted therapies have shown some activity in STS; however, disease stabilization is seen more often than a true radiographic response. The combination of cytotoxic chemotherapy with more targeted and novel agents may be appropriate to improve outcome in these patients. The agents of interest in sarcomas at this time are multi-tyrosine kinase inhibitors, antiangiogenesis agents, inhibitors of mammalian target of rapamycin, hypoxia-activating prodrugs, insulin growth factor monoclonal antibodies, and tumor necrosis factor-related apoptosis-inducing ligand agonists.

D., von Mehren, M., Antonescu, C. R., DeMatteo, R. P., Ganjoo, K. N., Maki, R. G., Pisters, P. W., Raut, C. P., Riedel, R. F., Schuetze, S., Sundar, H. M., Trent, J. C., Wayne, J. D. 2010; 8: S1-S43

    Abstract

    The standard of care for managing patients with gastrointestinal stromal tumors (GISTs) rapidly changed after the introduction of effective molecularly targeted therapies involving tyrosine kinase inhibitors (TKIs), such as imatinib mesylate and sunitinib malate. A better understanding of the molecular characteristics of GISTs have improved the diagnostic accuracy and led to the discovery of novel immunomarkers and new mechanisms of resistance to TKI therapy, which in turn have resulted in the development of novel treatment strategies. To address these issues, the NCCN organized a task force consisting of a multidisciplinary panel of experts in the fields of medical oncology, surgical oncology, molecular diagnostics, and pathology to discuss the recent advances, identify areas of future research, and recommend an optimal approach to care for patients with GIST at all stages of disease. The task force met for the first time in October 2003 and again in December 2006 and October 2009. This supplement describes the recent developments in the field of GIST as discussed at the October 2009 meeting.

    Abstract

    The American Cancer Society estimated 66,120 new cases of non-Hodgkin lymphoma (NHL) in the USA in 2008. Radioimmunotherapy has been shown in clinical trials to be an effective treatment for refractory/relapsed NHL. The available agents are Bexxar, a (131)I radiolabeled murine monoclonal antibody, and Zevalin, a (90)Y radiolabeled murine antibody. Both target CD20 receptors present on the surface of lymphocytes. We present our clinical experience with Bexxar and Zevalin in the management of low-grade refractory or relapsed NHL.This is a retrospective study (Jan 2000-Jul 2006) of 67 patients with NHL, who were treated with Bexxar (31 patients, group A) or Zevalin (36 patients, group B) for refractory/relapsed disease. Group A included 16 men and 15 women, 35-81 years old (average, 59.3 +/- 13.4). Group B included 27 men and nine women, 36-85 years old (average, 55.4 +/- 13.8). Therapeutic doses ranged 40-138 mCi (average, 78.1 +/- 28.2) for Bexxar and 17-34 mCi (average, 28.8 +/- 4.37) for Zevalin.Objective responses were induced in 22 of the 31 patients (70.9%) in group A and 28 of the 36 patients (77.8%) in group B. Complete response was noted in 11 patients (35.5%), partial response in seven patients (22.6%), and mixed response in four patients (12.9%) in group A. There were five patients (16.1%) with stable disease and four patients (12.9%) with disease progression in the same group. Complete response was noted in 15 patients (41.7%), partial response in nine patients (25%), and mixed response in four patients (11.1%) in group B. There were four patients (11.1%) with stable disease and another four patients (11.1%) with disease progression in the same group. The average decreases at posttherapy nadir were 36.9% +/- 0.33 (group A) and 52.6% +/- 0.32 (group B) for platelets, 27.8% +/- 0.27 (group A) and 34.2% +/- 0.38 (group B) for leukocytes, and 4.9% +/- 0.15 (group A) and 7.6% +/- 0.11 (group B) for hemoglobin. Grades 3 and 4 hematological toxicity occurred in 14 patients (45.2%) treated with Bexxar and 22 patients (61.1%) treated with Zevalin, but was reversible.Our study suggests that clinical practice of Bexxar and Zevalin radioimmunotherapy is an effective and safe adjunctive treatment for patients with NHL refractory/relapsed to conventional treatment. However, due to the small number of subjects, it was not possible to determine whether differences in the outcomes or toxicities from the two agents were statistically significant.

  • Antiangiogenesis Agents in the Treatment of Soft Tissue Sarcomas CANCER Ganjoo, K., Jacobs, C. 2010; 116 (5): 1177-1183

    Abstract

    Soft tissue sarcomas (STSs) are a heterogeneous group of malignancies that includes >50 different subtypes, each with unique clinical and pathologic qualities. In general, there is a 50% cure rate, and most cures are achieved with complete surgical resection with or without radiation therapy. The results from chemotherapeutic agents for unresectable or metastatic disease have been disappointing with minimal long-term benefit. New targeted and novel agents are needed to improve response and survival. Tumor angiogenesis has been an intense focus in cancer therapy over the past decade. Several of numerous antiangiogenesis agents have been developed, and many already have been approved for the treatment of both solid and liquid tumors. Certain STSs are highly vascular tumors that often demonstrate angiogenesis markers. The objective of this review was to evaluate these angiogenesis markers in defining the role of angiogenesis in the treatment of patients with STS. In addition, the authors conducted an in-depth review of the results from using key antiangiogenesis agents in the treatment of STS.

  • Bendamustine Is Effective Therapy in Patients With Rituximab-Refractory, Indolent B-cell Non-Hodgkin Lymphoma Results From a Multicenter Study CANCER Kahl, B. S., Bartlett, N. L., Leonard, J. P., Chen, L., Ganjoo, K., Williams, M. E., Czuczman, M. S., Robinson, K. S., Joyce, R., Van der Jagt, R. H., Cheson, B. D. 2010; 116 (1): 106-114

    Abstract

    Bendamustine hydrochloride is a novel alkylating agent. In this multicenter study, the authors evaluated the efficacy and toxicity of single-agent bendamustine in patients with rituximab-refractory, indolent B-cell lymphoma.Eligible patients (N = 100, ages 31-84 years) received bendamustine at a dose of 120 mg/m(2) by intravenous infusion on Days 1 and 2 every 21 days for 6 to 8 cycles. Histologies included follicular (62%), small lymphocytic (21%), and marginal zone (16%) lymphomas. Patients had received a median of 2 previous regimens (range, 0-6 previous regimens), and 36%were refractory to their most recent chemotherapy regimen. Primary endpoints included overall response rate (ORR) and duration of response (DOR). Secondary endpoints were safety and progression-free survival (PFS).An ORR of 75% (a 14% complete response rate, a 3% unconfirmed complete response rate, and a 58% partial response rate) was observed. The median DOR was 9.2 months, and median PFS was 9.3 months. Six deaths were considered to be possibly treatment related. Grade 3 or 4 (determined using National Cancer Institute Common Toxicity Criteria [version 3.0.19]. reversible hematologic toxicities included neutropenia (61%), thrombocytopenia (25%), and anemia (10%). The most frequent nonhematologic adverse events (any grade) included nausea (77%), infection (69%), fatigue (64%), diarrhea (42%), vomiting (40%), pyrexia (36%), constipation (31%), and anorexia (24%).Single-agent bendamustine produced a high rate of objective responses with acceptable toxicity in patients with recurrent, rituximab-refractory indolent B-cell lymphoma.

  • Trabectedin: an anticancer drug from the sea EXPERT OPINION ON PHARMACOTHERAPY Ganjoo, K. N., Patel, S. R. 2009; 10 (16): 2735-2743

    Abstract

    Trabectedin (ET-743) is an anticancer agent originally isolated from Ecteinascidia turbinata, a marine organism.The goal of this review is to describe the chemical characteristics, mechanism of action and the results of clinical trials with this compound. The toxicities are described, as well as the pharmacokinetics. The regulatory affairs and marketing strategies for this compound are also discussed.Medline and meeting proceedings were searched to accomplish our objectives.Trabectedin is a unique alkylating agent. It affects a variety of transcription factors, cell proliferation, and nucleotide excision repair mechanism. In addition, it inhibits the MDR-1 gene, which is responsible for the resistance of cancer cells to chemotherapeutic agents. The main toxicities of this agent are transaminitis and myelosuppression, both reversible and noncumulative. At present, trabectedin is approved in Europe for the treatment of sarcoma. The combination of this compound with other chemotherapeutics has been tested in Phase I studies in sarcomas and is feasible. This drug in combination with doxil has shown to improve outcome in relapsed ovarian cancer, compared with doxil alone. The results of this study may lead to an FDA approval of the combination in the USA, for the treatment of relapsed ovarian cancer.

  • Coordinate Expression of Colony-Stimulating Factor-1 and Colony-Stimulating Factor-1-Related Proteins Is Associated with Poor Prognosis in Gynecological and Nongynecological Leiomyosarcoma AMERICAN JOURNAL OF PATHOLOGY Espinosa, I., Beck, A. H., Lee, C., Zhu, S., Montgomery, K. D., Marinelli, R. J., Ganjoo, K. N., Nielsen, T. O., Gilks, C. B., West, R. B., van de Rijn, M. 2009; 174 (6): 2347-2356

    Abstract

    Previously, we showed that the presence of high numbers of macrophages correlates with poor prognosis in nongynecological leiomyosarcoma (LMS). In gynecological LMS, a similar trend was noted but did not reach statistical significance. Colony-stimulating factor-1 (CSF1) is a major chemoattractant for macrophages. Here we show that in a subset of LMS cases, CSF1 is expressed by the malignant cells. Previously, we found that CSF1 is translocated and highly expressed in tenosynovial giant cell tumors (TGCTs), and this observation allowed us to identify genes that showed a coordinate expression with CSF1. Here, we evaluated the expression of CSF1 and TGCT-associated proteins in 149 cases of LMS. The coordinate expression of CSF1 and three TGCT-associated proteins (CD163, FCGR3a, and CTSL1) identified cases with poor prognosis in both gynecological LMS (P = 0.00006) and nongynecological LMS (P = 0.03). In gynecological LMS, the coordinate expression of these four markers was the only independent prognosticator in multivariate analysis (hazard ratio, 4.2; 95% CI, 1.12 to 16; P = 0.03). Our findings indicate that CSF1 may play an important role in the clinical behavior of LMS that may open a window for new therapeutic reagents.

    Abstract

    PURPOSE: Angiosarcoma of the breast is a rare, malignant tumor for which little is known regarding prognostic indicators and optimal therapeutic regimens. To address this issue, we performed a retrospective analysis of breast angiosarcoma cases seen at Stanford University along with immunohistochemical analysis for markers of angiogenesis. METHODS: Breast angiosarcoma cases seen between 1980 and 2008 were examined. Viable tissue blocks were analyzed for expression of vascular endothelial growth factor and its receptors. RESULTS: A total of 16 cases were identified. Data was collected regarding epidemiology, treatment, response rates, disease-free survival, and the use of various imaging modalities. Five tissue blocks remained viable for immunohistochemical analysis. Vascular endothelial growth factor-A was positively expressed in 3 of these samples. CONCLUSION: Angiosarcoma of the breast is an aggressive malignancy with a propensity for both local recurrence and distant metastases. Angiogenesis inhibition may represent a novel therapeutic modality in this rare, vascular malignancy.

  • The importance of angiogenesis markers in the outcome of patients with diffuse large B cell lymphoma: a retrospective study of 97 patients JOURNAL OF CANCER RESEARCH AND CLINICAL ONCOLOGY Ganjoo, K. N., Moore, A. M., Orazi, A., Sen, J. A., Johnson, C. S., An, C. S. 2008; 134 (3): 381-387

    Abstract

    The role of angiogenesis has been extensively evaluated in solid tumors and more recently in hematologic malignancies. Several surrogate markers of angiogenesis including tumor VEGF, VEGF receptors, and microvessel density have correlated with outcome in some lymphoma studies. This is a single institution retrospective study evaluating the role of angiogenesis markers in the clinical outcome of patients with diffuse large B cell lymphoma (DLBCL).A total of 97 patients with DLBCL diagnosed and managed at Indiana University between 1993 and 2001 were included. Archived tumor samples were stained for VEGF-A, VEGF-C, VEGF-R1, and CD31 and graded as negative or positive (1+, 2+, 3+). The relationship between the expression of these markers and the international prognostic variables as well as the progression free survival (PFS) and the overall survival (OS) was evaluated.VEGF-A, VEGF-C, VEGF-R1 were expressed in 77, 98, and 18% of tumors, respectively. VEGF-A negative patients had an improved OS compared to VEGF-A (1+) (P = 0.0502). VEGF-C correlated with both LDH (r = 0.28, P = 0.0502) and IPI score (r = 0.25, P = 0.013). VEGF-R1 negative patients had a superior survival compared to those with VEGF-R1 (2+) (P = 0.0154).The presence of tumor associated angiogenesis may alter the outcome of patients with DLBCL and could be a prognostic factor. Further clinical studies are needed to correlate the degree of angiogenesis with response to anti-angiogenesis agents.

  • Review of erlotinib in the treatment of advanced non-small cell lung cancer. Biologics : targets & therapy Ganjoo, K. N., Wakelee, H. 2007; 1 (4): 335-346

    Abstract

    Epidermal growth factor receptor (EGFR) is a transmembrane receptor with a cytoplasmic tyrosine kinase (TK) domain present on many solid tumors including non-small cell lung cancer (NSCLC). Once stimulated by ligand, the downstream pathway is activated leading to cell growth, survival, and carcinogenesis. There are several methods of EGFR inhibition including monoclonal antibodies directed against the external region and small molecule inhibitors of TK domain. Erlotinib and gefitinib are orally available small molecule EGFR TK inhibitors, with proven efficacy in NSCLC. The most common side effects are skin toxicity and diarrhea. Erlotinib has been shown to improve survival compared to placebo in second or third-line therapy for NSCLC. However, erlotinib in combination with chemotherapy failed to show a survival advantage in two first-line studies which could be due to the timing of chemotherapy administration. In general, patients with adenocarcinoma histology, female gender, Asian ethnicity, and never smokers have a better response when treated with erlotinib. This could be related to the presence of EGFR mutations, lack of KRAS mutations, or overexpression of EGFR as measured by fluorescent in-situ hybridization (FISH) analysis. Future studies should concentrate on further development of predictors of clinical benefit with erlotinib, overcoming resistance to erlotinib that develops in initial responders, as well as more effective sequencing of erlotinib with chemotherapy and combinations of the drug with other "targeted" therapeutic agents.

  • Non-Hodgkin lymphoma of the breast CANCER Ganjoo, K., Advani, R., Mariappan, M. R., McMillan, A., Horning, S. 2007; 110 (1): 25-30

    Abstract

    Primary lymphoma of the breast has been reported to have a high local and central nervous system recurrence (CNS) rate, suggesting the need for consolidation radiotherapy and CNS prophylaxis. A retrospective study was done to evaluate the institutional experience in this patient population.In all, 37 patients with lymphoma involving the breast at initial diagnosis and managed at Stanford University from 1981-2005 were included. Diagnostic tissue biopsies were obtained either from the breast mass or an involved lymph node. Treatment and response data, patterns of recurrence, and outcomes were reviewed.Diffuse large B cell lymphoma (DLBCL) was the most common histologic subtype seen in 18 of 37 (49%) patients. Follicular and marginal zone subtypes were seen in 38%. Most patients presented with an incidental breast mass in stage I(E) or II(E). Four (11%) patients presented with bilateral breast involvement, with only 1 patient presenting with CNS disease. DLBCL patients received doxorubicin-based chemotherapy, with 70% receiving involved field radiotherapy and a single patient receiving intrathecal therapy. No recurrences occurred in the involved breast and a single parenchymal CNS recurrence was recorded. Among the DLBCL patients, the 5-year progression-free survival (PFS) was 61%, with a median follow-up of 3.8 years (range, 5 months to 19 years) and the 5-year overall survival (OS) was estimated at 82%. Patients with indolent lymphoma had an estimated 5-year PFS of 76% and an OS of 92%.DLBCL of the breast was successfully treated with doxorubicin-based chemotherapy alone or with involved field radiotherapy in an estimated 61% of patients at 5 years. A single CNS recurrence was observed in our series of patients, most of whom presented with limited disease.

  • Rituximab, Bevacizumab and CHOP (RA-CHOP) in untreated diffuse large B-cell lymphoma: Safety, biomarker and pharmacokinetic analysis LEUKEMIA & LYMPHOMA Ganjoo, K. N., An, C. S., Robertson, M. J., Gordon, L. I., Sen, J. A., Weisenbach, J., Li, S., Weller, E. A., Orazi, A., Horning, S. J. 2006; 47 (6): 998-1005

    Abstract

    Bevacizumab is a humanized monoclonal antibody directed against vascular endothelial growth factor (VEGF-A). Non-Hodgkin's lymphoma patients with high serum VEGF levels have an inferior survival compared to patients with low VEGF levels. Bevacizumab was administered through a central line at 15 mg kg(-1) IV on day 1 followed by rituximab (R) and CHOP on day 2 for cycle 1 and day 1 for cycles 2 - 8. Serum levels of bevacizumab and R were measured at specified time points to assess pharmacokinetics (PK). Plasma and urine samples were also analysed for VEGF. Tumor samples were stained for VEGF, CD31 and factor VIII by immunohistochemistry. Thirteen patients with newly-diagnosed DLBCL received a total of 88 cycles (range 2 - 8, median 7). Best response included five CR, six PR, one SD and one PD with an overall response rate of 85% and complete response rate of 38%. The 12-month PFS is 77% and a median follow-up of 16.9 months for the surviving patients. All tumor samples stained strongly positive for VEGF and there was a marginal association between baseline plasma VEGF and response (p = 0.04). Patients with higher plasma VEGF levels were generally younger and had bulky disease. Micro-vessel density did not correlate with presenting disease characteristics, VEGF expression or response. The PK of bevacizumab and rituximab were not influenced by combined treatment. In this patient population, treatment with RA-CHOP did not result in any episodes of grade 3 or 4 proteinuria, heart failure or hemorrhage. The RA-CHOP combination was generally well tolerated and safe.

  • Phase II clinical studies of denileukin diftitox diphtheria toxin fusion protein in patients with previously treated chronic lymphocytic leukemia CANCER Frankel, A. E., Surendranathan, A., Black, J. H., White, A., Ganjoo, K., Cripe, L. D. 2006; 106 (10): 2158-2164

    Abstract

    The safety and efficacy of the interleukin-2 diphtheria toxin fusion protein (DAB(389)IL2; denileukin diftitox) directed against the IL-2 receptor (IL-2R) was tested in patients with recurrent or refractory chronic lymphocytic leukemia (CLL).Denileukin diftitox was administered as 60-minute intravenous infusions for 5 days every 21 days at a dose of 18 mug/kg per day for up to 8 cycles. In total, 28 patients were treated in 2 multiinstitutional studies with similar eligibility criteria and treatment protocols. Twenty-two patients receive > or = 2 cycles of denileukin diftitox and were evaluable for response.Twelve of 22 patients achieved reductions of peripheral CLL cells, with 5 of 12 patients achieving >80% reductions. Six of 22 patients achieved reductions in the size of lymph node on examination and computed tomography scans, and all 6 of those patients met the criteria for a partial or complete response that lasted > or = 2 months. Bone marrow biopsies before and after treatment confirmed a complete remission that lasted for 1 year in 1 patient. Overall, denileukin diftitox produced complete remission in 1 of 22 patients (4%) and partial remission in 5 of 22 patients (23%) for a total remission rate of 27%. Progression-free intervals in the responders were 2 months in 2 patients and 4 months, 6 months, 7 months, and 12 months in 1 patient each. Toxicities were moderate. No infections associated with immunosuppression were seen. There was no significant correlation of response or toxicities with the numbers of denileukin diftitox cycles received or with CD25 levels.Follow-up studies will be required to identify predictors of response that may improve the response rate to denileukin diftitox in patients with CLL.

  • A phase II study of single agent gemcitabine in relapsed or refractory follicular or small lymphocytic non-Hodgkin lymphomas - A hoosier oncology group study AMERICAN JOURNAL OF CLINICAL ONCOLOGY-CANCER CLINICAL TRIALS Ganjoo, K. N., Robertson, M. J., Fisher, W., Jung, S. H., McClean, J., Huh, S. Y., Bufill, J., Williams, S., Cripe, L. D. 2005; 28 (2): 169-172

    Abstract

    Gemcitabine is a pyrimidine analog that is active in patients with aggressive lymphomas and Hodgkin disease. This study assessed tumor response in patients with previously treated follicular or small lymphocytic non-Hodgkin lymphoma. This was a 2-stage phase II trial with the first stage requiring 2 of 13 responses to proceed to the second stage. Gemcitabine was given as a single agent to patients with previously treated follicular or small lymphocytic lymphomas. Gemcitabine was administered at 1250 mg/m2 over 30 minutes on days 1 and 8 of a 21-day cycle for a maximum of 6 cycles. Thirteen patients were treated with 1 to 6 cycles of chemotherapy. Two patients experienced grade 4 toxicity with neutropenia. No grade 4 nonhematologic toxicity was seen. There was 1 partial response and 8 patients (61%) had either minimal response or stable disease. Single-agent gemcitabine administered at this dose and schedule produced 1 partial remission and half the patients had stable disease. However, the study had to be stopped early because of lack of meaningful response.

    Abstract

    To determine the response rate, duration of response and survival with weekly gemcitabine plus docetaxel in metastatic or unresectable pancreatic cancer.Forty patients were enrolled, and 38 patients were evaluable for survival and toxicity. Thirty-seven patients were evaluable for response. Nine patients (24%) had locally advanced disease and 29 (76%) had metastatic disease at the time of enrollment. Median Eastern Cooperative Oncology Group performance status was 1. Patients received gemcitabine 750 mg/m(2) i.v. and docetaxel 35 mg/m(2) i.v. weekly for 3 out of 4 weeks for a maximum of 6 cycles.Patients received a median of 4 cycles (range 1-6) of chemotherapy. An objective response was obtained in 10 patients (27%) with a median duration of 17 weeks. Median survival was 7 months, and 1-year survival was 19.3%. Eight patients experienced at least one form of grade 4 toxicity and 27 patients experienced at least one type of grade 3 toxicity.The combination of gemcitabine and docetaxel is a well-tolerated regimen with clinical efficacy. The ultimate role of this combination versus single-agent gemcitabine can only be determined by a randomized phase III trial.

  • A phase I study of weekly gemcitabine and docetaxel in patients with advanced cancer: A Hoosier Oncology Group study ONCOLOGY Ganjoo, K. N., GORDON, M. S., Sandler, A. B., Warner, R. E., Fife, K., Poirier, S., Seshadri, R., Loehrer, P. J. 2002; 62 (4): 299-304

    Abstract

    To determine the maximum tolerated dose (MTD) of weekly gemcitabine plus docetaxel, a dose escalation trial of both drugs was developed with each administered weekly for 3 weeks out of 4.Dose levels for gemcitabine (mg/m(2)) and docetaxel (mg/m(2)) were as follows: level 1: 600/25; level 2: 600/35; level 3: 750/35; and level 4: 900/35. Sixteen patients with adequate renal, hepatic, and hematologic function and an Eastern Cooperative Oncology Group performance status of 0-2 were treated. Primary sites included pancreas (12) and others (4).Three patients were treated at each dose level from level 1 through level 4. The dose-limiting toxicity (DLT) was neutropenia, the maximum tolerated dose being 750 mg/m(2) of gemcitabine and 35 mg/m(2) of docetaxel. No grade 4 nonhematologic toxicity was seen. Three patients had grade 4 neutropenia. Of the 12 patients with pancreatic cancer, 1 had a partial remission and 7 had stable disease with a median duration of 8 weeks.Gemcitabine and docetaxel can be safely administered weekly at a dose of 750 and 35 mg/m(2), respectively. The DLT was neutropenia. Disease stabilization suggests that this may be an active regimen in patients with metastatic pancreatic cancer.

  • Germ cell tumor associated primitive neuroectodermal tumors JOURNAL OF UROLOGY Ganjoo, K. N., Foster, R. S., Michael, H., Donohue, J. P., Einhorn, L. H. 2001; 165 (5): 1514-1516

    Abstract

    This retrospective review was done to assess the prognosis and response in patients presenting with primitive neuroectodermal tumor admixed with germ cell tumor.Of the 40 patients treated at our institution from 1984 to 1999, 15 had initial stage I and 25 had initial metastatic disease. Median followup after the diagnosis was 25 months (range 4 to 142).Of the 40 patients 15 presented with clinical stage I disease, including 9 treated with retroperitoneal lymph node dissection and 6 who elected surveillance. Seven of the 9 patients had normal lymph nodes and all continuously had no evidence of disease. Two of the 9 patients had lymph nodes involved with teratoma with or without primitive neuroectodermal tumor. Retroperitoneal relapse in 5 of the 6 patients on surveillance was treated with cisplatin based chemotherapy followed by post-chemotherapy retroperitoneal lymph node dissection. Residual primitive neuroectodermal tumor was noted in 4 of the 5 patients and only 3 of 6 are currently without disease at a median followup of 17 months (range 15 to 69). A total of 25 patients presented with metastatic disease, of whom 23 underwent cisplatin based chemotherapy. Only 3 patients achieved complete remission with chemotherapy alone and 2 of the 3 subsequently relapsed. Of the remaining 20 patients 16 underwent post-chemotherapy retroperitoneal lymph node dissection, including 11 with primitive neuroectodermal tumor in the resected specimen. Two of these 11 patients have continuously had no evidence of disease, while an additional 3 currently have no evidence of disease after further therapy. Teratoma was present in the resected specimen in 5 of 16 patients, of whom 2 have continuously had no evidence of disease, while an additional 2 currently have no evidence of disease after further surgical resection. Therefore, 11 of 25 patients who presented with metastatic disease currently have no evidence of disease at a median followup of 19 months (range 2 to 111).Primitive neuroectodermal tumor in the orchiectomy specimen has adverse prognostic significance. This condition in the retroperitoneum is potentially curable by retroperitoneal lymph node dissection but rarely eradicated by chemotherapy. Therefore, we recommend retroperitoneal lymph node dissection for all clinical stage I cases with primitive neuroectodermal tumor in the orchiectomy specimen. Patients who present with metastatic primitive neuroectodermal tumor should be treated aggressively with surgical resection as an integral part of the therapeutic strategy.

    Abstract

    The aim of this study was to determine the effects of independent prognostic variables, such as prechemotherapy tumor markers, the extent of disease at diagnosis, the tumor markers postchemotherapy (PC), and the pathology of the PC residual mass on the overall survival of patients with primary mediastinal nonseminomatous germ cell tumors (PMNSGCT).The authors undertook a retrospective review of 39 patients with PMNSGCT between 1983 and 1997 who received their initial chemotherapy at Indiana University and 36 additional patients referred for PC resection. All patients received chemotherapy based on the combination of cisplatin and etoposide. The median follow-up was 22 months (range, 12-144 months).The prechemotherapy tumor markers did not affect overall survival. Extent of disease (mediastinal only vs. visceral metastases) was an important prognostic factor for survival in univariate analysis (P = 0.042). Sixty-two of 75 patients underwent PC resection of residual disease. Fifteen of the 62 patients achieved a CR with chemotherapy alone, as the PC resection revealed only necrosis. Fourteen of these 15 patients continuously had no evidence of disease (NED). Forty-seven of the 62 patients had NED with chemotherapy and PC resection, including 31 with teratoma and 16 with carcinoma. However, 11 of 31 with teratoma and 11 of 16 with carcinoma subsequently relapsed. Although 18 patients had elevated tumor markers at the time of PC resection, 6 of 18 had only necrosis and 4 had teratoma. The PC tumor markers did not affect survival. The pathology of the resected specimen was the most significant predictor of survival in multivariate analysis (P < 0.001).Twenty-eight of 39 patients (71.8%) with PMNSGCT treated at Indiana University achieved NED status, but only 16 (41%) continuously had NED. Twenty of 36 (55.5%) referred for resection continuously had NED. Disease confined to the mediastinum and necrosis in the PC specimen were important prognostic factors for survival.

  • Positron emission tomography scans in the evaluation of postchemotherapy residual masses in patients with seminoma Ganjoo, K. N., Chan, R. J., Sharma, M., Einhorn, L. H. AMER SOC CLINICAL ONCOLOGY. 1999: 3457-3460

    Abstract

    To assess the ability of positron emission tomography (PET) scans in differentiating between necrosis and viable seminoma in postchemotherapy (PC) residual disease.We conducted a prospective study of 29 patients with seminoma at Indiana University. All patients had PC residual disease. Computed tomography and PET scans were performed for 19 patients after primary chemotherapy (group A) and for 10 patients after salvage chemotherapy (group B).In group A, the PC masses were >/= 3 cm in 14 patients, less than 3 cm in three patients, and not quantified in two patients. All of the patients in group A had negative PET scan results and have had stable or decreasing residual mass size (median follow-up duration, 11.5 months; range, 6 to 26 months). In group B, the PC masses were >/= 3 cm in four patients, less than 3 cm in five patients, and not quantified in one patient. One patient had a positive PET scan result for a posterior mediastinal mass. Pathologic diagnosis of the PET-positive mass showed only necrotic tissue. The same patient had a negative PET scan of the retroperitoneal mass but relapsed in that area. Overall, of patients in group B, five have stable or decreasing mass (median follow-up duration, 8 months; range, 7 to 22 months), and five had relapsed disease.PET scans have no apparent benefit in PC evaluation of residual masses in bulky seminoma.

  • Primary mediastinal nonseminomatous germ cell tumors: The influence of postchemotherapy pathology on long-term survival after surgery Kesler, K. A., Rieger, K. M., Ganjoo, K. N., Sharma, M., Fineberg, N. S., Einhorn, L. H., Brown, J. W. MOSBY-ELSEVIER. 1999: 692-700

    Abstract

    The treatment of nonseminomatous germ cell tumors with cisplatin-based chemotherapy followed by aggressive surgical resection of residual disease is one of the most successful models for multimodality cancer therapy. We reviewed the case histories of 91 patients treated at our institution from 1981 to 1998 with primary mediastinal nonseminomatous germ cell tumors to evaluate variables that may influence survival after surgery.Twelve of the 91 patients did not undergo postchemotherapy resection because of progressive disease. Seventy-nine of them underwent 82 thoracic surgical procedures and are the basis of this review. The majority (71/75) had elevated serum tumor markers, 75% (n = 50) of which returned to normal levels after first- or second-line chemotherapy.There were 3 operative deaths and 1 late death, attributed to pulmonary complications. Twenty-four patients died of recurrent disease and 3 of leukemia, for an overall survival of 61% after an average follow-up of 48 months. The pathologic findings of complete tumor necrosis (n = 19) and benign teratoma (n = 28) in the surgical specimen predicted excellent and good long-term survival, respectively, which was statistically better than that of patients having persistent nonseminomatous germ cell tumors (n = 24) or carcinomatous/sarcomatous degeneration (n = 8).Primary nonseminomatous germ cell tumors of the mediastinum can be cured with a multimodality therapy, particularly in the subset of patients with postchemotherapy pathologic findings of tumor necrosis and teratoma. Survival is poor but possible in patients with unfavorable pathologic findings after chemotherapy, currently justifying an aggressive surgical approach in patients with otherwise operable disease.
