PURPOSE: To investigate the interobserver variations in delineation of lumpectomy cavity (LC) and clinical target volume (CTV), and its impact on irradiated volume in accelerated partial breast irradiation using intraoperative multicatheter brachytherapy. MATERIAL AND METHODS: Delineation of LC and CTV was done by five radiation oncologists on planning computed tomography (CT) scans of 20 patients with intraoperative interstitial breast implant. Cavity visualization index (CVI), four-point index ranging from (0 = poor) to (3 = excellent) was created and assigned by observers for each patient...

Standard clinical care for breast cancer includes lumpectomy followed by localized radiotherapy or chemotherapy. However, both therapies cause loss of normal, healthy tissue in addition to tumor tissue, leading to undesirable side effects. In this study, we found that low dose and prolonged treatment with anticancer drug doxorubicin (DOX) can completely eliminate MDA-MB-231 breast cancer cells with low cytotoxicity to NIH 3T3 fibroblasts. We further developed a novel biomaterial-based drug delivery system for controlled and sustained release of low doses of DOX based on self-assembled dextran sulfate (DS)-DOX complexes...

Treatment of early-stage invasive breast cancer with breast-conserving surgery plus radiation therapy (RT) yields overall survival outcomes equivalent to those achieved with mastectomy. Further, breast-conserving surgery is endorsed by the National Comprehensive Cancer Network as being supported by the highest-level, category 1 evidence. Advances in pathologic evaluation, management of multiple tumors, oncoplastic lumpectomy techniques, neoadjuvant chemotherapy, and hypofractionated RT can expand the pool of patients eligible for breast-conserving surgery...

History In 2004, this woman received a diagnosis of invasive mammillary carcinoma, tubular variant, strongly positive for estrogen and progesterone receptors. Her lesion was found at screening mammography performed at an outside institution when she was 59 years old. She underwent partial mastectomy, with partial axillary node dissection and sentinel node mapping. A 0.6 × 0.5 cm Nottingham grade 1 infiltrating ductal carcinoma was removed from the right upper outer quadrant, margins were free of tumor, and there was no angiolymphatic invasion...

BACKGROUND: Acute radiation dermatitis (ARD) is a frequent complication after breast cancer radiotherapy and is usually assessed by semi-quantitative clinical scores, which may be subject to inter-observer variability. High-frequency ultrasound imaging of the skin can reliably quantify thickness and edema in diseased skin. We aimed to compare the relative increase in dermal thickness of the irradiated zone in breast-cancer patients undergoing radiotherapy, with clinical severity. METHODS: A consecutive series of patients undergoing treatment for breast cancer by lumpectomy and radiotherapy in a 6-month period also underwent clinical and ultrasound evaluation of ARD...

Lisa A Newman
Several prospective randomized clinical trials conducted internationally have proven the safety and survival equivalence of breast-conserving surgery compared with mastectomy. Adjuvant radiation is routinely recommended following lumpectomy surgery to minimize the risk of local recurrence. Comprehensive breast imaging (including bilateral mammography with diagnostic views and ultrasound evaluation), in addition to clinical examination, is essential to rule out potential contralateral pathology and to optimally characterize the extent of disease...

INTRODUCTION: The most common malignant tumour among women is breast carcinoma. Early lesions of the breast including carcinoma are potentially curable if treated properly in the era of breast conservative therapy. For this purpose different diagnostic strategies are in practice. Intra operative Imprint Cytology (IC) and Frozen Section (FS) have a role in spite of the intense recognition of aspiration cytology in the following settings: inconclusive cytological/core biopsy findings; for evaluation of lumpectomy margins and intra operative nodal status...

Hypnosis has been proven to be a powerful tool in the management of anxiety and pain. It allows for an increase of pain threshold, which can reach the level of surgical analgesia. Recently injection of local anesthetics around the serratus muscle has been presented as an alternative to paravertebral block for cancer breast surgery. We report the successful use of hypnosis in combination with an axillary compartment block for lumpectomy and axillary lymph node dissection.

BACKGROUND: Pre-operative measurements from the skin to a wire-localized breast lesion can differ from operating room measurements. This study was designed to measure the discrepancies and study factors that may contribute to wire movement. METHODS: Prospective data were collected on patients who underwent wire localization lumpectomy. Clip and hook location, breast size, density, and direction of wire placement were the main focus of the analysis. RESULTS: Wire movement was more likely with longer distance from skin to hook or clip, larger breast size (especially if "fatty"), longer time between wire placement and surgery start time, and medial wire placement in larger breast...

Introduction: In the modern context of multimodal treatment strategies for cancer patients with systemic disease, the dogma that surgery has a limited role is becoming less and less valid. Although a "œcurative" approach is not possible for the majority of the cases, however, some patients with limited systemic disease and favorable tumor biology could benefit from an aggressive combined cytotoxic and surgical strategy. CASE REPORT: A 48-year-old patient was diagnosed with an invasive ductal carcinoma with the immunohistochemistry positive for estrogen and progesterone receptors, positive Her2 and three liver metastases...

Breast cancer is the most common cancer among tunisian women and worldwide. In Cape Bon, Tunisia, the anatomopathological features of this cancer have not been established in previously published studies. Knowledge about these features is needed for the cultural adaptation of prevention and health care systems in the region. The aim of our study was to determine the pathological profile of breast cancers in the only public health anatomic pathology regional laboratory. We conducted a retrospective descriptive study of 116 patients who were diagnosed with breast cancers in our laboratory over a 5-year period, from July 2010 to July 2015...

Male breast cancer (MaBC) is a rare disease, accounting for less than 1% of malignancies in men. For this reason, literature data on its clinicopathological characteristics are very heterogeneous and treatment strategies have mostly been extrapolated from the female counterpart. However, immunohistochemical peculiarities of MaBC have recently emerged, defining it as a distinct entity from female breast cancer (FBC), thus requiring a tailored clinical approach. MaBC appears to be more often hormone receptor positive than FBC, while data on HER2 status still remain inconclusive, indicating a possible higher incidence of HER2 alterations...

Objective: We describe a modification of the inferior pedicle reduction mammoplasty for oncoplastic reconstruction of a central tumor defect. Our technique involved a deepithelialized L-shaped medial inferior based flap with removal of lateral breast tissue after central lumpectomy with a contralateral Wise-pattern mastopexy with inferior pedicle for symmetry. This technique is ideal for patients with large, ptotic breasts that desire breast conservation with immediate reconstruction. Methods: A 47-year-old woman with size 38 DD breasts presented with a palpable 2-cm subareolar mass of the left breast...

The purpose of this study is to evaluate the intensity modulated radiotherapy (IMRT) with the fixed collimator jaws technique (FJT) for the left breast and regional lymph node. The targeted breast tissue and the lymph nodes, and the normal tissues were contoured for 16 left-sided breast cancer patients previously treated with radiotherapy after lumpectomy. For each patient, treatment plans using different planning techniques, i.e., volumetric modulated arc therapy (VMAT), tangential IMRT (tangential-IMRT), and IMRT with FJT (FJT-IMRT) were developed for dosimetric comparisons...

BACKGROUND: Multiple randomised trials and meta-analyses have supported the use of conservative surgery (CS) and radiation therapy (RT) for the treatment of early-stage breast cancer. Following lumpectomy, RT has been shown to decrease the chance of local recurrence and improve overall survival when compared with lumpectomy alone. OBJECTIVE: This update outlines the rationale and outcomes for CS and RT, whether a subgroup exists in which RT may be safely omitted, the process of RT, common side effects and their management, and the latest techniques in the field...

PURPOSE: To identify factors which predict, among estrogen receptor (ER)-positive breast cancer patients, who chooses to take adjuvant tamoxifen. METHODS: We studied 1347 women with ER-positive breast cancer who were treated at Women's College Hospital between 1987 and 2000. For each patient, we obtained information on age at diagnosis, tumour size, lymph node status, ER status, treatments received and dates of local recurrence and of death. We compared women who did and who did not take tamoxifen for a range of factors...

The aim of the present study was to summarize the clinical characteristics of primary breast lymphoma (PBL) and evaluate its management approaches. A total of 29 patients newly diagnosed with PBL, and treated between April 2006 and May 2013, were analyzed retrospectively. The median survival follow-up time for all patients was 66.8 (range, 25.4-110.0) months. The results of the follow-up revealed 22 living lymphoma-free patients and 7 patients who had succumbed to PBL. Of the 7 deceased patients, 6 had succumbed to lymphoma and 1 to chemotherapy-associated hepatic failure...
