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. IOeRT was administered using SIT LIAC HWL®.
Results: A total of 28 patients were referred for breast conservation surgery and IOeRT between 8/2019 and 10/2020; 27/28 received IOeRT. In one patient, radiation was aborted due to anaphylactic shock in response to patent blue dye injected for sentinel node identification. Larger than usual seroma were reported on the first post-operative visit in all patients, and regressed spontaneously in 3-6 months. Infected seroma developed post-operatively in 5 patients, requiring surgical drainage in 2 patients. Final pathology matched the preoperative biopsy. There were no cases of pathology upstaging requiring additional adjuvant irradiation or chemotherapy. The patient who did not receive IOeRT was treated with adjuvant external radiotherapy.
Conclusions: IOeRT is a safe alternative to partial breast irradiation, with a slight increase of postoperative infection rate.

The potential benefits of pyrotinib for patients with trastuzumab-insensitive, HER2-positive early-stage breast cancer remain unclear. This prospective, multicentre, response-adapted study evaluated the efficacy and safety of adding pyrotinib to the neoadjuvant treatment of HER2-positive breast cancer patients with a poor response to initial docetaxel plus carboplatin and trastuzumab (TCbH). Early response was assessed using magnetic resonance imaging (MRI) after two cycles of treatment.

Background: Breast cancer is the leading cause of female cancer mortality worldwide, accounting for 1 in 6 cancer deaths. Surgery, radiation, and systemic therapy are the three pillars of breast cancer treatment, with several strategies developed to combine them. The association of preoperative radiotherapy with immunotherapy may improve breast cancer tumor control by exploiting the tumor radio-induced immune priming.

Breast cancer (BC) is the most prevalent cancer in women globally. Anti-cancer advancements have enabled the killing of BC cells through various therapies; however, cancer relapse is still a major limitation and decreases patient survival and quality of life. Epithelial-to-mesenchymal transition (EMT) is responsible for tumor relapse in several cancers.

Background: In the realm of implant-based breast reconstruction, mastectomy flap necrosis (MFN) is a prevalent yet grave complication that poses a threat to the stability of the inserted prosthesis. Although numerous investigations have scrutinized the risk factors for MFN development, few have delved into the aftermath, specifically implant failure or salvage. This study seeks to appraise the prognosis of the implanted prosthesis following MFN occurrence, as well as identify predictors of such outcomes.

Purpose/objective: Partial breast irradiation (PBI) delivered with intensity modulated radiation therapy (IMRT) over five fractions every other day (QOD) represents an attractive, convenient method of delivering adjuvant radiation therapy for well selected patients without compromising oncologic or toxicity outcomes. Condensing this regimen to a week of treatment through consecutive daily delivery may further increase patient convenience, though comparison of toxicities between daily and QOD regimens are limited.
Materials/methods: We retrospectively reviewed 507 patients from an institutional registry undergoing PBI for DCIS or early-stage breast cancer (T1-2N0/x) from 2015 to 2022.
