Oncoplastic Breast Surgery: Optimizing Resection Margins in Addition to Aesthetic Outcomes

Area of Science:

• Oncology
• Surgical Oncology
• Breast Surgery

Background:

• Oncoplastic breast surgery offers superior aesthetic outcomes compared to lumpectomy alone.
• Limited data exists on the oncologic benefits of oncoplastic breast surgery.

Purpose of the Study:

• To evaluate if oncoplastic surgery improves resection margins versus lumpectomy alone in breast conserving therapy.
• To determine the impact of oncoplastic surgery on re-excision rates.

Main Methods:

• Retrospective cohort study of 4,673 breast cancer patients (2010-2023).
• Comparison of re-excision rates within 6 months between lumpectomy alone and oncoplastic surgery groups.
• Propensity score matching used to adjust for confounders.

Main Results:

• Oncoplastic surgery prevalence increased significantly over the study period (p=0.04).
• Re-excision rates were 17% for lumpectomy alone vs. 13% for oncoplastic surgery.
• Oncoplastic surgery was associated with significantly lower odds of re-excision (OR 0.7, p=0.05) after adjustment.

Conclusions:

• Oncoplastic surgery may enhance the achievement of clear surgical margins in breast conserving therapy.
• Increasing adoption of oncoplastic surgery suggests its growing acceptance and potential benefits.
• Offering oncoplastic surgery to appropriately selected patients is recommended.
