Round block technique and modified round block technique as a cornerstone of oncoplastic breast surgery for early breast cancer

. ABSTRACT Background: A level II volume displacement oncoplastic breast surgery method, the round block, and modified round block procedures entail sufficient tumor removal with a good esthetic result. Peripheral and periareolar lesions are treated with them. Wide local excision could be carried out with ease and a satisfactory safety margin, and the breast tumor was excised with a sufficient macroscopic safety margin. The goal of contemporary breast surgery is to treat patients by repairing and maintaining breast tissue, producing favorable physical and psychological results. Aim: To evaluate the application of modified and round block procedures in oncoplastic breast surgery for early-stage breast cancer. Patients and Methods: Twenty-one patients with breast cancer who were scheduled to have surgery between June 2019 and June 2020 utilizing round block and modified round block procedures were included in the research. Our study’s sample age ranged from 25 to 61 years old, with an average age of 46. Results: The mean age is 46 (range, 25–61 years old) and the tumor size ranges from 1 to 4 cm. Inflammation, wound infection, and gap and local dermatitis are the main postoperative complications and three (14.28%) patients were affected. All specimens were free safety margins with no recurrence. The cosmetic results are excellent in nearly all patients (90.47%), except three (14.28%) patients who had good cosmetic results. Conclusion: Round block and modified round block provide good tumor access and oncological control around the breast with little scar formation and safety. There were neither subsequent changes in the shape nor the position of the areola.
