PURPOSE: Reduction mammoplasty (RM) during breast-conserving surgery is popular among women with large-volume breasts because it reduces redundant breast folds and may decrease skin-related morbidity from radiation therapy. However, RM may obscure the lumpectomy cavity (LC) and pose challenges to administering an LC boost, potentially affecting local control. We investigated the impact of RM on acute side effects and use of LC boosts. METHODS AND MATERIALS: The records of 645 consecutive women treated with whole-breast irradiation at an urban university and 2 community practices between January 2012 and December 2014 were reviewed on an institutional review board-approved study...

BACKGROUND: Irradiation of implant-based breast reconstructions (BR) is known to increase capsular contracture (CC) rates on average by 4-fold over non-irradiated reconstructions. The use of acellular dermal matrix (ADM) has been associated with lower CC rates in non-irradiated reconstructions (0-3%). Experimental and clinical studies suggest that ADM may also reduce CC rates in irradiated breasts. The aim of this study was to evaluate CC rates in non-irradiated and irradiated one- and two-stage BRs performed with the assistance of porcine ADM (PADM)...

BACKGROUND: Immediate breast reconstruction (IBR) after mastectomy has shown to be oncologically safe and to improve quality of life in breast cancer patients. However, most women undergoing mastectomy do not undergo IBR. In this study, we aim to identify breast surgeon-related factors in considering IBR and factors affecting patients' decision to choose for IBR. METHODS: Retrospective analysis of the records of breast cancer patients who underwent mastectomy with or without IBR between 2010 and 2013...

The renin-angiotensin system (RAS) is a principal determinant of arterial blood pressure and fluid and electrolyte balance. RAS component dysregulation was recently found in some malignancies and correlated with poor patient outcomes. However, the exact mechanism of local RAS activation in tumors is still unclear. Here, we find that the local angiotensin II predominantly exists in the hypoxic regions of tumor formed by nasopharyngeal carcinoma CNE2 cells and breast cancer MDA-MB-231 cells, where these tumor cells autocrinely produce angiotensin II by a chymase-dependent rather than an angiotensin converting enzyme-dependent mechanism...

Mediastinal radiation is commonly used to treat Hodgkin's and non-Hodgkin's lymphoma, lung and breast cancer. Cardiac complications after radiation therapy are well described, although rare. A large spectrum of injuries can occur, causing long term morbidity among survivors. We describe a case of post-actinic ascending aortic wall thickening that prevented saphenous vein proximal anastomosis and was successfully managed with aortic no-touch off-pump coronary artery bypass grafting (OPCAB), 25 years after radiation therapy for Hodgkin's lymphoma...

BACKGROUND: In women who require post-mastectomy radiation therapy, immediate autologous breast reconstruction is often discouraged. We aim to prospectively evaluate postoperative morbidity and satisfaction reported by women undergoing delayed or immediate autologous breast reconstruction in the setting of post-mastectomy radiation therapy. METHODS: Patients enrolled in the Mastectomy Reconstruction Outcomes Consortium Study, who received post-mastectomy radiotherapy and had immediate or delayed free abdominal-based autologous breast reconstruction were identified...

BACKGROUND: The role of postmastectomy radiotherapy (PMRT) for women with pT3N0M0 breast cancer is controversial. We sought to determine the benefit of PMRT in this cohort using the National Cancer Database (NCDB). METHODS: We analyzed women with pT3N0M0 breast cancer who received mastectomy with or without PMRT between 2004 and 2012. We excluded men, women ≤18 years, neoadjuvant or unknown radiation or chemotherapy status, unknown estrogen or progesterone receptor status, unknown surgical margin status, histology other than invasive ductal or lobular carcinoma, and if death occurred <3 months after diagnosis...

REVIEW
Frank W Hensley
Literature was reviewed to assess the physical aspects governing the present and emerging technologies used in intraoperative radiation therapy (IORT). Three major technologies were identified: treatment with electrons, treatment with external generators of kV X-rays and electronic brachytherapy. Although also used in IORT, literature on brachytherapy with radioactive sources is not systematically reviewed since an extensive own body of specialized literature and reviews exists in this field. A comparison with radioactive sources is made in the use of balloon catheters for partial breast irradiation where these are applied in almost an identical applicator technique as used with kV X-ray sources...

BACKGROUND: The shift towards an earlier diagnosis of breast cancer (BC) highlights the need for biomarkers that would identify patients at risk for relapse and metastatic spread and indicate the potential value of additional treatment strategies. Osteopontin (OPN) is a matricellular protein that has been suggested to be a potential biomarker in BC. In the present study, we used archived BC patient samples to assess the clinical utility of OPN. METHODS: Formalin-fixed paraffin-embedded tumor tissue samples from 975 patients were collected from two large phase III randomized adjuvant chemotherapy trials (HE10/97 and HE10/00) that included patients with high risk BC...

PURPOSE: Adjuvant radiation therapy (RT) in breast cancer treatment has been proven to enhance outcome, improving recurrence and mortality rates. RT, however, gives rise to unfavourable side-effects, fatigue the most frequent. The aim of this study was to assess the effect of exercise (and different exercise prescription parameters) during adjuvant RT on fatigue among breast cancer patients. Quality of life was a secondary outcome. SEARCH METHODOLOGY AND SELECTION CRITERIA: Randomised controlled trials that investigated the effect of exercise during adjuvant RT on fatigue for breast cancer patients were searched using MEDLINE, EMBASE, Google Scholar, CINAHL, AMED and ClinicalTrials...

The process and technicalities of radiation therapy (RT) for cancer treatment can be challenging for patients to understand as RT involves complex procedures, highly specialised equipment, and radiation itself has limited sensory characteristics. Hence, it is imperative that education programs are specifically planned and developed to suit the needs of patients, address radiation as an entity and include salient visual aids. In this context, the Virtual Environment for Radiotherapy Training (VERT) system, primarily created for RT practitioner simulation, may provide unique opportunities for patient education...

BACKGROUND AND OBJECTIVE: Brachytherapy is a form of radiation therapy using sealed radiation sources inserted within or in the vicinity of the tumor of, e.g., gynecological, prostate or head- and neck cancers. Accurate dose calculation is a crucial part of the treatment planning. Several reviews have called for clinical software with model-based algorithms that better take into account the effects of patient individual distribution of tissues, source-channel and shielding attenuation than the commonly employed TG-43 formalism which simply map homogeneous water dose distributions onto the patient...

CONTEXT: College of American Pathologists (CAP) and the American Society of Clinical Oncology have emphasized the need to reduce preanalytic variables for evaluating predictive biomarker expression in breast cancer. Postoperative x-ray of excised breast tissue is commonplace, yet is a variable that has not been investigated previously. We asked whether such radiation affects expression of relevant biomarkers. DESIGN: A previous study found that human breast cancers grown in mice demonstrate the same immunohistochemical and molecular profiles as the original tumors...
