Background: The modified round block technique (MRBT) is a surgical approach used in the breast-conserving management of early breast cancer, for achievement of optimal oncological safety while preserving breast aesthetics. It involves a periareolar incision with minimal scarring, that allow for adequate tumor excision and reshaping of the breast tissue. Aim: To improve the oncological safety and cosmetic outcome in the surgical management of breast cancer Patients and Methods: This study was conducted on 72 female patients admitted to the Surgical Oncology Unit, Zagazig University Hospital, who were eligible for breast conserving therapy (BCT). A circumferential incision was made with preservation of the periareolar skin, followed by subcutaneous dissection through the entire breast. Postoperative patient satisfaction was evaluated using the Harvard scale. Results: the operative time ranged from 90 to 260 minutes, with a mean ± SD of 138.1 ± 52.7. About 58.3% of the patients showed no complications, while (27.8%) of the patients showed seroma and (13.9%) of the patients showed wound infection. Also 55.6% of the patients showed excellent results, (27.8%) showed good results, and (16.7%) showed fair results, while none of the patients showed poor results. About 83.3% of the patients were satisfied, while (16.7%) of the patients were not satisfied. Conclusion: The MRBT is an oncoplastic technique suitable for the excision of breast tumors in different breast quadrants especially peripherally located tumors in patients with small to medium-sized breasts. It is oncologically safe and has fewer complications.
