The locoregional management of breast cancer in men has evolved over time. Multimodality treatment regimens currently in use are based primarily on large randomized trials that exclusively enrolled women with breast cancer. We retrospectively reviewed cases of male breast cancer treated with radiotherapy at Stanford University Medical Center with an emphasis on 22 patients treated with surgery and locoregional radiotherapy. We report trends in the surgical techniques as well as in the use of adjuvant radiotherapy, chemotherapy, and hormonal therapy. There were no isolated locoregional failures in this cohort, and 5-year disease-free survival was 65%. The use of contemporary surgical and radiotherapeutic techniques in men is discussed. We conclude that treatment guidelines designed for women should be applied to the locoregional management of breast cancer in men. However, large international prospective registries and inclusion of men in cooperative group randomized trials will be important to confirm the safety and efficacy of modern treatment modalities for male breast cancer.

ACR Appropriateness Criteria (R) Ductal Carcinoma in Situ
2012; 18 (1): 8-15
Despite the success of both breast conserving surgery and mastectomy, some women will experience a local-regional recurrence (LRR) of their breast cancer. Predictors for LRR after breast-conserving therapy or mastectomy have been identified, including patient, tumor, and treatment-related factors. The role of surgery, radiation, and chemotherapy as treatment has evolved over time and many patients now have the potential for salvage after LRR. This review of LRR of breast cancer and management recommendations, including the use of common clinical scenarios, represents a compilation of evidence-based data and expert opinion of the American College of Radiology Appropriateness Criteria Expert Panel on local-regional recurrence. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

ACR Appropriateness Criteria (R) Locally Advanced Breast Cancer
2011; 17 (6): 579-585
Ductal carcinoma in situ (DCIS) describes a wide spectrum of non-invasive tumors which carry a significant risk of invasive relapse, thus prevention of local recurrence is vital. For appropriate patients with limited disease, management with breast conserving surgery (BCS) followed by whole-breast radiation (RT) is supported by multiple Phase III studies, but mastectomy may be appropriate in selected patients. Omission of RT may also be reasonable in some patients, though which criteria are to be utilized remain unclear, and the existing data are contradictory with limited follow-up. Various RT techniques such as boost to the tumor bed, partial breast radiation or hypofractionated, whole-breast RT are increasingly utilized but the data to support their use specifically in DCIS is limited. Tamoxifen also increases local control for ER?+?DCIS, adding to the complexity of the local treatment management. This article reviews the existing scientific evidence, the controversies surrounding local management, and clinical guidelines for DCIS based on the group consensus by the ACR Breast Expert Panel. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel.

ACR Appropriateness Criteria (R) Conservative surgery and Radiation - Stage I and II Breast Carcinoma
2011; 17 (5): 448-455
Locally advanced breast cancer (LABC) is a disease that is heterogeneous in its presentation, potentially curable, and generally necessitating multidisciplinary management. Radiation therapy (RT) plays an important role in the management of LABC. The integration of radiation with surgery, chemotherapy, and sometimes breast reconstruction can be complex. The American College of Radiology Appropriateness Criteria Breast Committee aims to provide guidance for the management of a variety of LABC cases. The American College of Radiology Appropriateness Criteria is evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is either lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

Phyllodes tumors of the breast: natural history, diagnosis, and treatment.
Journal of the National Comprehensive Cancer Network
2007; 5 (3): 324-330
Breast conservation is a safe and effective alternative to mastectomy for the majority of women with early-stage breast cancer. Adjuvant radiation therapy lowers the risk of recurrence within the breast and also confers a survival benefit. Although acute side effects of radiation therapy are generally well tolerated; efforts are ongoing to minimize the long-term side effects of radiation, most prominently atherosclerotic heart disease. Efforts to minimize radiation therapy are also underway. They include omitting treatment altogether in the elderly and using accelerated, hypofractionated whole-breast irradiation, and accelerated partial-breast irradiation. Several randomized studies are ongoing to determine the efficacy, safety, and appropriate patients for these shorter treatments.

Predictors of local recurrence after breast-conservation therapy.
Clinical breast cancer
2005; 5 (6): 425-438
Phyllodes tumors of the breast are unusual fibroepithelial tumors that exhibit a wide range of clinical behavior. These tumors are categorized as benign, borderline, or malignant based on a combination of histologic features. The prognosis of phyllodes tumors is favorable, with local recurrence occurring in approximately 15% of patients overall and distant recurrence in approximately 5% to 10% overall. Wide excision with a greater than 1 cm margin is definitive primary therapy. Adjuvant systemic therapy is of no proven value. Patients with locally recurrent disease should undergo wide excision of the recurrence with or without subsequent radiotherapy.

Breast-conserving therapy (BCT) is a proven local treatment option for select patients with early-stage breast cancer. This paper reviews pathologic, clinical, and treatment-related features that have been identified as known or potential predictors for ipsilateral breast tumor recurrence in patients treated with BCT. Pathologic risk factors such as the final pathologic margin status of the excised specimen after BCT, the extent of margin involvement, the interaction of margin status with other adverse features, the role of biomarkers, and the presence of an extensive intraductal component or lobular carcinoma in situ all impact the likelihood of ipsilateral breast tumor recurrence. Predictors of positive repeat excision findings after conservative surgery include young age, presence of an extensive intraductal component, and close or positive margins in prior excision. Finally, treatment-related factors predicting ipsilateral breast tumor recurrence include extent of breast radiation therapy, use of a boost to the lumpectomy cavity, use of tamoxifen or chemotherapeutic agents, and timing of systemic therapy with irradiation. The ability to predict for an increased risk of ipsilateral breast tumor recurrence enhances the ability to select optimal local treatment strategies for women considering BCT.
