Outcomes of oncoplastic breast surgery compared to breast-conserving surgery in breast cancer patients in a developing country: a retrospective cohort study
Abstract
Background and Objective: Breast-conserving surgery (BCS) with adjuvant radiotherapy remains the standard of care for early breast cancers in Pakistan. We sought to compare the outcomes of BCS with oncoplastic surgery (OPS), a relatively infrequent approach to breast cancer treatment in the country.
Methods: This retrospective cohort study was conducted at Aga Khan University Hospital and Ziauddin Hospital in Karachi. Patients who had biopsy-proven Stage-I to III breast cancer and underwent either OPS or BCS between August 1, 2016, and December 31, 2021, were identified and followed for 30 days. Data were collected by reviewing patient files and electronic records.
Results: A total of 481 patients were included in the study, where 204 (42.4%) underwent BCS and 277 (57.6%) underwent OPS. Mean tumor volume (146.8 vs. 90.4 cm3), and postoperative complications (2.2 % vs. 0%) were higher in OPS while the frequency of positive margins was greater in the BCS group (15.7 % vs. 2.2 %). There were no significant differences in the histologic type of tumor between the two groups.
Conclusion: OPS is a valid alternative approach to breast cancer treatment that can be offered to women with early stage, locally advanced, multifocal or tumors at complex locations owing to the reduced occurrence of positive margins and thus lowered re-excision rates.
