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: Early reconstruction after mastectomy for breast cancer with definitive implants has been widely used, especially with the evolution of conservative surgical breast cancer treatments. We aimed to identify different characteristics associated with plastic surgery, based on immediate or delayed reconstruction time and evaluate quality of life in patients undergoing mastectomy for cancer. METHODS: This is a cross-sectional analytical study that evaluated adult patients undergoing mastectomy for breast cancer and breast reconstruction in Plastic Surgery Service at a tertiary hospital...

Tumor expression of programmed cell death ligand 1 (PD-L1) is associated with immune evasion in a variety of malignancies, including a subset of triple-negative breast carcinomas, and may mark cancers as susceptible to PD-1/PD-L1 inhibitor therapies. We herein characterize PD-L1 expression in breast cancers across the full range of histomorphologies and investigate its intratumoral heterogeneity and fidelity across primaries and metastases. A total of 245 primary and 40 metastatic (20 nodal, 20 distant) breast carcinomas were evaluated with PD-L1 immunohistochemistry on tissue microarray...

INTRODUCTION: A large heterogeneous group of unproven remedies exist to treat cancer in both developed and developing countries. Some of these remedies often do more harm than good to the patients. The traditional medicine is the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures. The traditional medicine in Oman is based on herbal treatment and skin treatment (massage, Cupping and skin burn "cautery" treatment-known as Wasam or Kaiy)...

Purpose: Several accelerated partial breast radiation (APBR) techniques have been investigated in patients with early-stage breast cancer (BC); however, the optimal treatment delivery techniques remain unclear. We evaluated the feasibility and toxicity of APBR delivered using intensity-modulated radiation therapy (IMRT) in elderly patients with stage I BC, using a novel fractionation schedule. Materials and Methods: Forty-two patients aged ≥65 years, with stage I BC who underwent breast conserving surgery were enrolled in a phase I/II study evaluating APBR using IMRT...

BACKGROUND: Although breast cancer is most prevalent among older women, the majority are diagnosed at an early stage. When diagnosed at an early stage, women have the option of breast-conserving surgery (BCS) plus radiation therapy (RT) or mastectomy for the treatment of early-stage breast cancer (ESBC). Omission of RT when receiving BCS increases the risk for recurrence and poor survival. Yet, a small subset of older women may omit RT after BCS. This study examines the current patterns of local treatment for ESBC among older women...

Inhibition of cyclin dependent kinases (CDKs) 4 and 6 prevent cells from entering the synthesis phase of the cell cycle. CDK4 and 6 are therefore important drug targets in various cancers. The selective CDK4/6 inhibitor palbociclib is approved for the treatment of breast cancer and has shown activity in a cellular model of mixed lineage leukaemia (MLL)-rearranged acute myeloid leukaemia (AML). We studied the interactions of palbociclib and CDK6 using molecular dynamics simulations. Analysis of the simulations suggested several interactions that stabilised the drug in its binding site and that were not observed in the crystal structure of the protein-drug complex...

INTRODUCTION: Consensus about surgical treatment options for breast cancer in elderly patients remains elusive due to exclusion from clinical trials. Fear of complications due to increased age often is an important factor in the choice of treatment and might result in different treatment of the older patient. METHODS: A total of 1258 female patients who underwent breast cancer surgery for primary diagnosed breast cancer in 2010-2014 were included. Incidence of postoperative complications (POCs) was compared between the younger (18-70 years, N = 1008) and older (≥71 years, N = 250) patients...

INTRODUCTION: For patients who have an ipsilateral breast cancer recurrence following prior breast-conserving surgery and radiation, total mastectomy generally is recommended. However, little is known about the suitability and outcomes of nipple-sparing mastectomy (NSM) with immediate breast reconstruction for the treatment of recurrent breast cancer, prompting this investigation. PATIENTS AND METHODS: From 1008 patients scheduled for NSM for breast cancer treatment at our institution between January 2009 and June 2016, we identified all patients who underwent surgery for ipsilateral recurrent breast cancer...

Primary endocrine therapy is an option in cases of hormone receptor positive and HER2 negative non-metastatic breast cancer. Aromatase inhibitors are considered therapy of choice in postmenopausal patients. In premenopausal patients aromatase inhibitors in combination with LHRH-analogues are regarded superior to tamoxifen. Three different settings have to be discriminated: • Patients too frail for surgery are candidates for primary endocrine therapy in order to control the disease. Treatment duration is determined by the course of the disease...

: 195 Background: Breast cancer patients face difficult decisions about their surgical care without a full understanding of their options. The learning health system goal is to use information from the care of prior patients to inform the care of future patients. We aim to apply this concept to generate data-driven surgical paths, develop interactive path visualizations to inform patients, and evaluate their impact. METHODS: We used cancer registry and administrative CPT codes for women diagnosed with stage 0-III breast cancer between FY2010-14 at a comprehensive cancer center...

: 76 Background: Shared decision making (SDM) is a cornerstone of patient-centered care with 85-90% of breast cancer (BC) patients preferring an active or shared role in decision-making for breast surgery. SDM has been shown to, improve patients' understanding of treatment options, result in more conservative care choices, and lead to lower healthcare costs. However, implementation is complex as numerous misconceptions exist. METHODS: We are conducting a multi-site, quality improvement (QI) project to improve SDM behaviors and adherence to quality measures through a combination of provider education and use of a novel technology platform, the Carevive Care Planning System...

BACKGROUND: Most women with ductal carcinoma in situ (DCIS) will receive breast-conserving surgery (BCS) and radiation (RT). RT can be omitted for women at low risk of local recurrence (LR). The Oncotype DX DCIS score (DS) predicts LR risk after BCS alone. This study assesses the impact of RT and DS on LR risk. METHODS: Population-based cohort analysis of individuals with DCIS treated by BCS ± RT from 1994-2003. Treatment and outcomes were determined by linkage and chart review...

PURPOSE: Radiotherapy (RT) after breast-conserving surgery for early-stage breast cancer patients has similar survival benefits with whole breast RT (WBRT) or accelerated partial breast irradiation (APBI). However, the impact of RT type and side-effects severity on change in quality of life (QOL) is unknown. We examined changes in RT side-effects severity and QOL by RT type. METHODS: We analyzed data from a cohort of 285 newly diagnosed early-stage breast cancer patients with tumor size ≤3...

Although neoadjuvant chemotherapy has been widely adopted as it increases breast conservation rates, permits the in vivo testing of the activity of chemotherapeutics and offers the opportunity to conduct translational research based on longitudinal assessments of tumor tissue, neoadjuvant endocrine therapy has been met with skepticism owing to slow regression rates and a low chance for pathologic remission. Areas Covered: Herein, the results of clinical trials comparing different endocrine agents as neoadjuvant treatment, endocrine therapy with chemotherapy, treatment duration, novel combinations and putative biomarkers are reviewed, with the aim to better understand the current and future role of this modality in clinical practice...
