CLASSIC VERSUS MODIFIED ROUND BLOCK MASTOPEXY IN BREAST CANCER PATIENTS

Objective: The objective of the current study is to compare between round block technique (RBT); also known as doughnut mastopexy or peri-areolar mastopexy and modified round block technique (MRBT) regarding operative time, oncological safety margin, cosmetic outcome and complications. Methods: This prospective randomized controlled trial (RCT) study comprised 20 female patients with early stage breast cancer that were treated at KASR ALAINY teaching hospital - Faculty of Medicine, Cairo University, between October 2018 and February 2019. Patients were randomly divided into two groups (A&B) to compare the RBT with the MRBT. Operative time was calculated, oncological safety margin was determined by histopathological examination of the specimen, cosmetic outcome was assessed by two methods BCCT. core (breast cancer conservation treatment. cosmetic results) and BRA (breast retraction assessment). Moreover, post-operative complications were evaluated in the breast outpatient clinic during the follow-up period. Results: MRBT showed better cosmetic outcome through assessment by BCCT. core (p-value 0.367) and BRA (p value= 0.03). Also, it showed shorter operative time than the RBT. The mean operative time was 89.75, 69.88 minutes in group A and B respectively. Regarding complications there was 1 reported case with post-operative seroma formation (8.4%) in group A (RBT), while there were 2 cases (25%) that developed seroma in group B (MRBT). Conclusion: MRBT gives a better cosmetic results and shorter operative time than the RBT especially in peripherally located tumors and in small sized areolas.
