Abstract PURPOSE: To develop recommendations for management of patients with breast cancer (BC) with germline mutations in BC susceptibility genes. METHODS: The American Society of Clinical Oncology, American Society for Radiation Oncology, and Society of Surgical Oncology convened an Expert Panel to develop recommendations based on a systematic review of the literature and a formal consensus process. RESULTS: Fifty-eight articles met eligibility criteria and formed the evidentiary basis for the local therapy recommendations; six randomized controlled trials of systemic therapy met eligibility criteria. ...

ConclusionsThis survey shows a fairly good use of hRT and a moderate practice of PBI in Italy. Some practices like hRT to the chest wall and regional lymph nodes as well as rRT need further verification. Likewise, the management of post-NAC RT is very heterogeneous. Future national clinical collaborative studies are advocated in order to investigate these controversial topics about breast cancer radiotherapy.

Conclusions: This study is the first to demonstrate a dose-response relationship between risk of complications and near Dmax, where hypofractionated regimen or boost RT can play an important role. Rigorous RT-quality assurance program and modification of dose constraints could be considered as a critically important component for ongoing trials of hypofractionation. Based on our findings, we initiated a multi-center retrospective study (KROG 18-04) and a prospective study (NCT03523078) to validate our findings. Introduction Breast reconstruction provides important psychosocial, cosmetic, and quality of life benefits ...

We aimed to determine the significance of multifocal regression after neoadjuvant chemotherapy as a predictor of ipsilateral breast tumor recurrence (IBTR) in the modern era. In this retrospective review of 346 patients, multifocal regression, hormone receptor-negative phenotype, and lack of nodal pathologic complete response predicted for increased risk of IBTR on multivariate analysis. Although more common in hormone receptor-positive disease, multifocal regression was associated with worse outcome only in hormone receptor-negative patients.

Authors: Nurudeen S, Hunt KK Abstract The care of patients with breast cancer in the modern era involves a multimodal approach to treating locoregional and distant disease. Recent studies have demonstrated that the extent of surgical intervention in both the breast and axilla can be minimized through a personalized approach based on breast cancer stage, subtype, and planned adjuvant therapies. The older approach focused on complete removal of the axillary contents for appropriate staging and to determine the need for adjuvant systemic therapy and radiation. This approach has been replaced by sentinel lymph node bio...

Abstract PURPOSE: This multi-institutional study intended to investigate the effect of tumor bed boost in patients who achieved pathologic complete response (ypCR) following neoadjuvant chemotherapy (NAC) and breast-conserving therapy (BCT). MATERIALS AND METHODS: We identified 180 patients who initially had lymph node (LN) metastasis and achieved ypCR (ypT0/isN0) following NAC and BCT from the 13 institutions of the Korean Radiation Oncology Group (KROG) 16-16 and KROG 12-05. The effect of tumor bed boost on loco-regional control (LRC), disease-free survival (DFS), and overall survival (OS) rates was analyze...

We examined 411 patients with PABC and 83,381 patients with non-PABC. Over time, the proportions of patients undergoing breast-conserving surgery and sentinel lymph node biopsy increased, and neoadjuvant chemotherapy and radiation therapy administration rates also increased. In the past, the overall survival of patients with PABC was poorer than that of patients with non-PABC, but there was no difference in overall survival rates in more recent years. There was no difference in overall survival rates between patients who received neoadjuvant chemotherapy (hazard ratio [HR], 1.28; 95% confidence interval [CI], 0.66-2.49; p=...

In this study, the effect of a subcutaneous spacer injection on the skin dose, late skin toxicity, and cosmetic outcome is tested in patients treated with PBSI in the setting of breast-conserving therapy. Our results will be relevant for most forms of breast brachytherapy as well as robotic radiosurgery, as skin spacers could protect the skin with these other techniques.Trial registrationNetherlands Trial Register,NTR6549.

ConclusionsAfter NAC, most patients received irradiation of the breast/chest wall and axillary and supraclavicular nodes. In this setting, PORT to breast/chest wall with or without regional nodal irradiation was safe and effective, with acceptable disease-free and overall survival rates reported in this high-risk population.
