Endoscopy‑assisted breast‑conserving treatment: the first Polish review of 30 patients.

INTRODUCTION: Minimally-invasive procedures in breast surgery have gained popularity due to their favorable cosmetic outcomes and oncological results comparable to those achieved with conventional techniques. However, this approach has not been yet widely adopted in Poland, and its availability is limited to a small number of hospitals in Europe. AIM: This study aimed to evaluate the safety and feasibility of the first Polish endoscopic breast-conserving surgeries (E-BCSs). MATERIALS AND METHODS: A total of 30 patients who underwent E-BCS at 2 breast cancer centers in Poland between July 2024 and September 2025 were included in the study. We assessed short-term outcomes of E-BCS in women with early breast cancer or precancerous lesions qualified for local wide excision. Median (interquartile range) observation time was 8 (6-13.25) months. RESULTS: All procedures were completed without conversion to open surgery. No severe complications were observed. Postoperative surgical site infection occurred in 1 patient (3.3%). Three patients (10%) required reoperation due to positive margins. CONCLUSIONS: Our preliminary data indicate that E-BCS offers a low risk of complications and short-term safety and feasibility. Its outcomes are comparable to those of conventional surgery, making it a viable alternative to standard procedures.
