Purpose: The aim of this study was to evaluate the rate of axillary node-positive disease in patients with early breast cancer who had a suspicious axillary lymph node on radiation planning computed tomography (CT).
Methods And Materials: A retrospective review was conducted of the medical records of all patients with breast cancer who were referred for axillary ultrasound from the radiation unit to the breast imaging unit at the Meirav Breast Center, Sheba Medical Center, from 2012 to 2022. Ethics approval was obtained.
Aims: This study presents our experience with Intra-Operative Electron Radio-Therapy (IOeRT) using a mobile linear accelerator at the Sheba Medical Center.
Background: Intraoperative radiotherapy is an alternative approach of partial breast irradiation for patients with early breast cancer and low risk for local recurrence who are undergoing breast conservation surgery.
Methods: Patients were selected by a multidisciplinary team according to ASTRO\GEC-ESTRO guidelines for partial breast irradiation.
Female BRCA1/BRCA2 mutation carriers may elect bilateral risk-reducing mastectomy. There is a paucity of data on yield of imaging surveillance after risk-reducing mastectomy. This retrospective study focused on female BRCA1/BRCA2 mutation carriers who underwent bilateral mastectomy either as primary preventative, or as secondary preventative, after breast cancer diagnosis.

Methods: Israeli female cancer-free BRCA1/BRCA2 mutation carriers, who were followed at the high-risk clinic at Sheba Medical Center between January 2011 and April 2020 were eligible.
Background: Annual MRI screening is associated with a significant reduction in advanced-stage breast cancer diagnosis in BRCA1/2 mutation carriers. The impact that early detection has on subsequent oncological treatment is less frequently reported. In this study we compared disease stage and therapeutic approaches in BRCA1/2 mutation carriers who developed breast cancer while adhering to the recommended surveillance scheme ("known carriers"), with women who became aware of their BRCA mutation status after breast cancer diagnosis ("latent carriers").

Autologous TIL cultures are isolated from resected tumor tissue, expanded ex vivo to large numbers and reinfused to the preconditioned patient. In this prospective study, we validate the origin of the tumor biopsy and its effect on T-cell function and clinical response.

From a neo-adjuvant systemic therapy database of 588 breast cancer cases, 80 triple-negative cases who had undergone BRCA genotyping were identified. Logistic regression model was fitted to examine the association between BRCA1 status and pathological complete response.

Claudin-low breast cancers (CLBC) overlap with characteristics of BRCAmut tumors; therefore, we have investigated whether these are identical subtypes.
Methods: Using public gene expression data, CLDN, CDH1, 9-cell line claudin-low predictor (9CLCLP) and PAM50 expression was evaluated in BRCAmut and BRCA wild-type (BRCAwt) breast cancer cases focusing on their possible overlap with the CLBC subtype.
Background: Laparoscopic adjustable gastric banding (LAGB) is an effective bariatric procedure with low morbidity and mortality. Unfortunately, it is fraught with high failure rates in long-term follow-up. Laparoscopic sleeve gastrectomy (LSG) is an emerging procedure, quickly gaining momentum in the arsenal of bariatric practice as a first step toward gastric bypass/biliopancreatic diversion or as a stand-alone operation.

Although objective response rates of over 50% have been reported, disadvantages of this approach are the labor-intensive TIL production and a very high drop-out rate of enrolled patients, limiting its widespread applicability. Previous studies showed a clear correlation between short TIL culture periods and clinical response.

We have investigated the protective effect of defined extracellular matrix components and of extracellular matrix from different cell types (fibroblasts, hepatocytes and intestinal epithelial cells) on the toxicity of three types of chemotherapeutic drugs on colon cancer cells. Human colon cancer cell lines LS174T and LiM6 were plated on plastic, on hepatocyte-derived ECM or on stromal ECM and in the presence of the antimetabolite 5-fluorouracil (5-FU).
