Purpose Incidental cardiac irradiation can cause cardiac injury, but little is known about the effect of radiation on specific cardiac segments. Methods For 456 women who received breast cancer radiotherapy between 1958 and 2001 and then later experienced a major coronary event, information was obtained on the radiotherapy regimen they received and on the location of their cardiac injury. For 414 women, all with documented location of left ventricular (LV) injury, doses to five LV segments were estimated. For 133 women, all with documented location of coronary artery disease with ≥ 70% stenosis, doses to six coronary artery segments were estimated...

BACKGROUND: While breast cancer has historically been treated with surgery followed by adjuvant chemotherapy (AC) and radiation when indicated, neoadjuvant chemotherapy (NAC) use is thought to be increasing; however, the trends of its use in various biological subtypes have not been evaluated. We sought to evaluate the trend of NAC use over time by biological subtype. METHODS: We identified all patients with invasive breast cancer who underwent curative intent surgery and were treated with chemotherapy from 2010 to 2015 from the National Cancer Database...

Background and aim: The purpose of breast-conserving surgery (BCS) for women with cancer is to perform an oncological radical procedure with disease-free margins at the final histological assessment and with the best aesthetic result possible. Intraoperative resected specimen ultrasound and intraoperative resected specimen mammography may reduce the rates of positive margins and reexcision among patients undergoing conserving therapy. Our objective is to compare the two methods with the histopathological results for a preset cut off and asses which parameters can influence the positive margin status...

INTRODUCTION: The pathogenic mechanism underlying capsular contracture is still unknown. It is certainly a multifactorial process, resulting from human body reaction, biofilm activation, bacteremic seeding, or silicone exposure. The scope of the present article is to investigate the effect of hypofractionated radiotherapy protocol (2.66 Gy × 16 sessions) both on silicone and polyurethane breast implants. METHODS: Silicone implants and polyurethane underwent irradiation according to a hypofractionated radiotherapy protocol for the treatment of breast cancer...

The aim of this study is to assess the complication profile and impact on patient-reported quality of life in those undergoing nipple-sparing mastectomy (NSM) with immediate breast reconstruction and subsequent prosthetic reconstruction in patients with prior breast radiation therapy (pRT) vs those receiving adjuvant post-mastectomy radiation therapy (PMRT). An IRB-approved, retrospective analysis was performed from 2002 to 2014 to identify NSM patients that underwent pRT or PMRT. A 22-item Likert scale questionnaire was administered by a third party to register patient-reported quality of life...

OBJECTIVES: Intraoperative radiotherapy (IORT) relates to irradiation of diseased tissue during the surgery within the tumor bed. The reason for this process is based on the fact that the increase in the radiation dose increases local tumor control. It was shown that postoperative fluids obtained from patients after breast cancer conserving surgery, stimulated motility and invasiveness of tumor cells in vitro. The results obtained from TARGIT clinical trial demonstrated that IORT significantly inhibits the stimulatory effect of wound fluids on tumor cells in vitro...

BACKGROUND: Rates of mastectomy for breast cancer treatment and immediate reconstruction continue to rise. With increasing scrutiny on outcomes and patient satisfaction, there is an impetus for providers to be more deliberate in deciding appropriate patient selection for breast reconstruction. The Breast Reconstruction Risk Assessment (BRA) Score was developed for prediction of complications after primary prosthetic breast reconstruction, focusing on calculating risk estimations for a variety of complications based on individual patient demographics and perioperative characteristics...

Radiotherapy is an indispensable unit of multidisciplinary treatment of breast cancer. Although the application of modern techniques has led to a significantly reduction in radiation-induced heart disease, it is still recognized as the leading causes of morbidity and mortality among breast cancer survivors. With the growing number of long-term survivors, it is important to understand the cardiovascular risks associated with radiotherapy. Questions exist regarding the existence or not of a safe radiation threshold dose that the heart (or its substructures) can receive and strategies to minimize risk of radiation...

The topic of breast cancer prevention is very broad. All aspects of the topic, therefore, cannot be adequately covered in a single review. The objective of this review is to discuss strategies in current use to prevent breast cancer, as well as potential approaches that could be used in the future. This review does not discuss early detection strategies for breast cancer, including breast cancer screening. The breast is the most common site among women worldwide of noncutaneous cancer. Many clinical and genetic factors have been found to increase a woman's risk of developing the disease...

AIMS: Deep inspiration breath hold (DIBH) reduces cardiac radiation exposure by creating cardiac-chest wall separation in breast cancer radiotherapy. DIBH requires sustaining chest wall expansion for up to 40 s and involves complex co-ordination of thoraco-abdominal muscles, which may not be intuitive to patients. We investigated the effect of in-advance preparatory DIBH coaching and home practice on cardiac doses. MATERIALS AND METHODS: Successive patients from 1 February 2015 to 31 December 2016 with left-sided breast cancer who underwent tangential field radiotherapy utilising the DIBH technique were included...

Milwaukee Shoulder Syndrome (MSS) is a painful progressive arthropathy in which hydroxyapatite crystal deposition in synovial tissue induces lysosomal release of collagenase and neutral proteases. These enzymes are destructive to periarticular tissue, including the synovium, articular cartilage, rotator cuff muscles, and the intrasynovial cortical bone. MSS predominantly occurring in women (90%) over the age of 70 years of age with a clinical history marked by recurrent joint effusions and pain, which classically worsens at night...

Few studies of breast cancer treatment have focused on the Northern Plains of the United States, an area with a high mastectomy rate. This study examined the association between geographic access to radiation therapy facilities and receipt of breast cancer treatments among early-stage breast cancer patients in South Dakota. Based on 4,209 early-stage breast cancer patients diagnosed between 2001 and 2012 in South Dakota, the study measured geographic proximity to radiation therapy facilities using the shortest travel time for patients to the closest radiation therapy facility...

Triple-negative breast cancer (TNBC) is one of the most aggressive types of cancer, and treatment is limited to chemotherapy and radiation. Oncolytic virotherapy may be a promising approach to treat TNBC. However, oncolytic adenovirus (OAd)-based mono-therapeutic clinical trials have resulted in modest outcomes. The OAd potency could be increased by chemotherapy-induced autophagy, an intracellular degradation system that delivers cytoplasmic constituents to the lysosome. In this study, the ability of alkylating agent temozolomide (TMZ)-induced autophagy to increase OAd replication and oncolysis in TNBC cells was evaluated...

Radiation-induced coronary heart disease (RICHD) is the second most common cause of morbidity and mortality in patients treated with radiotherapy for breast cancer, Hodgkin's lymphoma and other prevalent mediastinal malignancies. The risk of RICHD increases with radiation dose. Exposed patients may present decades after treatment with manifestations ranging from asymptomatic myocardial perfusion defects to ostial, triple-vessel disease and sudden cardiac death. RICHD is insidious, with a long latency and a tendency to remain silent late into the disease course...

INTRODUCTION: Development of digital breast tomosynthesis (DBT) provides a technology that generates three-dimensional data sets, thus reducing the pitfalls of overlapping breast tissue. Observational studies suggest that the combination of two-dimensional (2D) digital mammography and DBT increases diagnostic accuracy. However, because of duplicate exposure, this comes at the cost of an augmented radiation dose. This undesired adverse impact can be avoided by using synthesised 2D images reconstructed from the DBT data (s2D)...
