Stanford APBI Trial

Clinical Trial

Overview

Intraoperative Radiotherapy (IORT) is one of three approaches used for accelerated, partial breast irradiation at Stanford.

Accelerated, partial breast irradiation (APBI) is a potentially important new way to incorporate radiotherapy in the treatment of women with breast cancer.

Currently, women with breast cancer who undergo a lumpectomy  typically have 6 1/2 weeks of radiation to the entire affected breast after surgery.  Accelerated, partial breast irradiation (APBI) changes this approach in two ways. It shortens the treatment time from 6 1/2 weeks to between 1 to 5 days, and reduces the treatment area from the entire breast to the area of the breast immediately around the lumpectomy site. This is the part of the breast where most cancers are likely to recur.

In many ways APBI is to current whole breast radiotherapy what a lumpectomy is to a mastectomy. The goal is to use a less invasive more focused treatment without compromising survival.

APBI has been used in limited trials in several hundred patients over the last 10 years. These trials show that in properly selected breast cancer patients APBI  worked just as well as whole breast radiotherapy. In the initial studies, investigators relied on the placement of many catheters in the breast tissue (interstial brachytherapy). Newer techniques will hopefully provide the same good results but will deliver the radiation in faster and/or more convenient ways. This could increase interest in APBI and allow additional clinical trials that test the safety and effectiveness of the newer approaches. These newer approaches could increase quality of life for many women with breast cancer.

Investigators at Stanford University Medical Center are currently offering an IRB approved clinical trial that uses three new approaches for APBI. These three approaches are:

    Intraoperative Radiotherapy (IORT) - 1 day

    Intracavitary Brachytherapy (MammoSite) - 5 days

    3-D Conformal/External Beam Radiotherapy - 5 days

The Stanford trial is led by Dr. Frederick Dirbas, Assistant Professor of Surgery, and by Dr. Donald Goffinet, Professor of Radiation Oncology. For further information about the trial please contact Janelle Maxwell or Triona Dolphin at (650) 498-7740.

  • Efficacy and Safety Comparison of Niraparib to Placebo in Participants With Human Epidermal Growth Factor 2 Negative (HER2-) Breast Cancer Susceptibility Gene Mutation (BRCAmut) or Triple-Negative Breast Cancer (TNBC) With Molecular Disease

    This study will assess the efficacy and safety of Niraparib in participants with either tumor mutation in the BRCA gene (tBRCAmut) HER2- breast cancer (Independent of hormone receptor [HR] status, including HR positive [+] and TNBC) or tumor BRCA wild type (tBRCAwt) TNBC with molecular disease based on the presence of circulating tumor Deoxyribonucleic acid (ctDNA) following surgery or completion of adjuvant therapy.

  • Everolimus in Patients With Pancreatic Neuroendocrine Tumors Metastatic to the Liver Previously Treated With Surgery

    This randomized phase II trial studies how well everolimus works in treating patients with pancreatic neuroendocrine tumors metastatic to the liver previously treated with surgery. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving everolimus after surgery may kill any tumors cells that remain.

  • Irinotecan Hydrochloride, Temozolomide, and Dinutuximab With or Without Eflornithine in Treating Patients With Relapsed or Refractory Neuroblastoma

    This phase II trial studies how well irinotecan hydrochloride, temozolomide, and dinutuximab work with or without eflornithine in treating patients with neuroblastoma that has come back (relapsed) or that isn't responding to treatment (refractory). Drugs used in chemotherapy, such as irinotecan hydrochloride and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as dinutuximab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Eflornithine blocks the production of chemicals called polyamines that are important in the growth of cancer cells. Giving eflornithine with irinotecan hydrochloride, temozolomide, and dinutuximab, may work better in treating patients with relapsed or refractory neuroblastoma.

  • Evaluation of an Electronic Health Record-based Screening Tool for Peripheral Artery Disease

    This protocol represents a pilot randomized-controlled trial evaluating the effect of an electronic health record (EHR)-based peripheral artery disease (PAD) screening tool on rates of new non-invasive testing, diagnosis and treatment of PAD over a 6-month period. An EHR-based PAD screening tool will be applied to the Stanford EHR, which will generate a group of patients of varying risks of having undiagnosed PAD. Patients with the highest risk of having undiagnosed PAD will then be evaluated for inclusion in this study. 1:1 randomization will be performed on a consecutive basis until study enrollment is completed (25 patients per arm).

    Physicians of patients randomized to the intervention arm will be sent notification via an EHR message detailing the patient's risk of undiagnosed PAD and suggestions for referral to vascular medicine for risk assessment and/or non-invasive ankle brachial index (ABI) testing. The primary outcome is number of patients receiving ABI testing for PAD at 6 months, with secondary outcomes including number of new PAD diagnoses, number of new referrals to cardiovascular specialists (vascular medicine, vascular surgery, and/or cardiology) and number of patients receiving initiation of new cardiovascular medications (anti-platelet agents, statins, and/or antihypertensive agents).

  • Dasatinib and Combination Chemotherapy in Treating Young Patients With Newly Diagnosed Acute Lymphoblastic Leukemia

    This phase II/III trial is studying the side effects and how well giving dasatinib together with combination chemotherapy works in treating young patients with newly diagnosed acute lymphoblastic leukemia (ALL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving dasatinib together with combination chemotherapy may kill more cancer cells.

  • Comparing Sentinel Lymph Node (SLN) Biopsy With Standard Neck Dissection for Patients With Early-Stage Oral Cavity Cancer

    This phase II/III trial studies how well sentinel lymph node biopsy works and compares sentinel lymph node biopsy surgery to standard neck dissection as part of the treatment for early-stage oral cavity cancer. Sentinel lymph node biopsy surgery is a procedure that removes a smaller number of lymph nodes from your neck because it uses an imaging agent to see which lymph nodes are most likely to have cancer. Standard neck dissection, such as elective neck dissection, removes many of the lymph nodes in your neck. Using sentinel lymph node biopsy surgery may work better in treating patients with early-stage oral cavity cancer compared to standard elective neck dissection.

  • Erlotinib Hydrochloride or Crizotinib and Chemoradiation Therapy in Treating Patients With Stage III Non-small Cell Lung Cancer

    This randomized phase II trial studies how well erlotinib hydrochloride or crizotinib with chemoradiation therapy works in treating patients with stage III non-small cell lung cancer. Radiation therapy uses high energy x rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin, etoposide, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving erlotinib hydrochloride is more effective than crizotinib with chemoradiation therapy in treating patients with non-small cell lung cancer.

  • Cognitive Processing Therapy (CPT) for Posttraumatic Stress Disorder and Borderline Personality Disorder (PTSD-BPD)

    Posttraumatic Stress Disorder (PTSD) with co-occurring Borderline Personality Disorder (BPD) (i.e., PTSD-BPD) is common (as high as 58%), debilitating, costly, and limited treatment options available for this population. PTSD-BPD is associated with even greater functional impairment and higher healthcare burden than either disorder alone. There are surprisingly few treatments available for this clinical profile, despite its association with major negative health outcomes, cost, and morbidity. There is a pressing need to innovate treatments that can effectively and efficiently treat PTSD-BPD. The existing treatments used for PTSD-BPD are lengthy, laborious, resource-intensive, and require complete cessation of suicidal behaviors prior to treatment. Furthermore, no integrated treatment has been innovated to deliver the active ingredients to efficiently affect the mechanisms underpinning this comorbidity. The investigators propose to examine an adapted version of a first-line PTSD intervention, Cognitive Processing Therapy, augmented with a Suicide Risk Management, i.e., (CPT+SRM) as a brief (12 sessions) and more parsimonious treatment alternative that strategically targets shared mechanisms underpinning PTSD and BPD. The purpose of this pilot study is to 1) collect initial feasibility, acceptability, and safety data on this adapted treatment, 2) conduct a pilot randomized clinical trial evaluating the efficacy of CPT+SRM versus Treatment as Usual (TAU) + SRM, and 3) evaluate two targets (i.e, improvements in emotional intensity and cognitive dysfunction) as mechanisms leading to change in our primary outcomes. Both treatment conditions will be administered via telehealth.

    Potential benefits include reduction in participants' PTSD, BPD and other mental health symptoms. Additionally, this work could benefit the community by improving the treatment repertoire for PTSD-BPD. Potential risks include emotional distress, suicidality, and/or self-harm. Participants may experience discomfort and/or distress while discussing participants trauma(s) and mental health. These risks will be mitigated using a suicide risk management protocol which therapists in the assessment of risk and protective factors of suicide, followed by documentation for the decision-making around the management of risk.

  • Efficacy of Oral Azacitidine Plus Best Supportive Care as Maintenance Therapy in Subjects With Acute Myeloid Leukemia (AML) in Complete Remission

    This study enrolled 472 participants, aged 55 or older, with a diagnosis of de novo acute myeloid leukemia (AML) or AML secondary to prior myelodysplastic disease or chronic myelomonocytic leukemia (CMML), and who have achieved first complete remission (CR)/ complete remission with incomplete blood count recovery (CRi) following induction with or without consolidation chemotherapy.

    The study is amended to include an extension phase (EP). The EP allows participants who are currently receiving oral azacitidine and who are demonstrating clinical benefit as assessed by the investigator, to continue receiving oral azacitidine after unblinding by sponsor until the participant meets the criteria for study discontinuation or until oral azacitidine becomes commercially available and reimbursed. In addition, all participants in the placebo arm and participants who had been discontinued from the treatment phase (irrespective of randomization arm) and continuing in the follow-up phase will be followed for survival in the EP.

  • Efficacy and Safety of Pembrolizumab (MK-3475) With Platinum Doublet Chemotherapy as Neoadjuvant/Adjuvant Therapy for Participants With Resectable Stage II, IIIA, and Resectable IIIB (T3-4N2) Non-small Cell Lung Cancer (MK-3475-671/KEYNOTE-671)

    This trial will evaluate the safety and efficacy of pembrolizumab (MK-3475) in combination with platinum doublet neoadjuvant chemotherapy (NAC) before surgery [neoadjuvant phase], followed by pembrolizumab alone after surgery [adjuvant phase] in participants with resectable stage II, IIIA, and resectable IIIB (T3-4N2) non-small cell lung cancer (NSCLC). The primary hypotheses of this study are that neoadjuvant pembrolizumab (vs. placebo) in combination with NAC, followed by surgery and adjuvant pembrolizumab (vs. placebo) will improve: 1) event free survival (EFS) by biopsy assessed by local pathologist or by investigator-assessed imaging using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1); and 2) overall survival (OS).

  • Gastrointestinal Microbiota in Primary Sclerosing Cholangitis and Biliary Atresia With Vancomycin

    The goals of the proposed work are two fold:

    Firstly, to see if the antibiotic vancomycin may be used for the early treatment of Biliary Atresia (BA) and Primary Sclerosing Cholangitis (PSC). The investigators hope to learn what effect Vancomycin has on the bacteria that are present in stool, body fluid or intestinal tissue on someone who has BA and PSC and if so by what mechanism. Secondly, the investigators hope to learn to characterize human intestinal microbial communities (microbiome: the collection or collectivity of microorganisms) using molecular methods, examine the mechanisms of interaction between host and microbiome using genomic approaches, and determine how the microbiome both preserves local health and promotes pathology. The investigators will focus on primary sclerosing cholangitis, biliary atresia, as well as states of health. The composition of the associated microbiome will be assessed based on ribosomal DNA and RNA sequences, and attention will be given to richness (diversity), evenness (relative abundance), and variation with respect to time, person, and anatomic niche. Host response at the adjacent mucosal surface will be assessed based on genome-wide gene expression patterns.
