Oncoplastic or Conventional Breast-Conserving Surgery? Outcomes from a West Java Retrospective Cohort Study

Area of Science:

• Oncology
• Surgical Oncology
• Breast Cancer Research

Background:

• Breast-conserving surgery (BCS) followed by radiotherapy is standard for early breast cancer in Indonesia.
• Oncoplastic surgery (OPS) is a less common but emerging alternative treatment.

Purpose of the Study:

• To compare the outcomes of BCS with OPS for early-stage breast cancer.
• To evaluate the efficacy and complication rates of both surgical approaches.

Main Methods:

• Retrospective cohort study at Hasan Sadikin General Hospital, Indonesia.
• Inclusion of 82 patients with Stage I-II breast cancer undergoing BCS or OPS between July 2020 and June 2023.
• Data collected via patient files and electronic records.

Main Results:

• Higher mean tumor volume in the OPS group (34.72 cm³ vs. 22.35 cm³).
• Increased postoperative complications in the OPS group (7.6% vs. 0%).
• Lower rate of positive margins in the OPS group (2.5% vs. 9.3%) despite BCS using frozen section analysis.

Conclusions:

• OPS is a valid alternative for early breast cancer, particularly for tumors in complex locations.
• OPS offers reduced positive margins, potentially decreasing the need for re-excision surgeries.
• Further research may explore optimizing OPS techniques to minimize complications.
