When a patient undergoes surgery for breast cancer, the goal is to remove the tumor while preserving as much healthy tissue as possible. One major concern is the surgical margin, which is the edge of the tissue removed. If cancer cells are found at that edge, the patient may need a second surgery to ensure all cancer is gone. This can be a stressful and physically demanding experience.
A large review of over 120,000 cases compared two methods: conventional breast-conserving surgery and oncoplastic breast-conserving surgery (OBCS). The results showed that patients who had the oncoplastic approach were less likely to have a positive margin initially. They also faced a lower risk of needing a re-excision, a conversion to a mastectomy, or any other operation related to the margins.
While the study showed fewer repeat procedures for those with oncoplastic surgery, it did not find a difference in the rate of local cancer recurrence. There were some notes regarding complications; while some reports showed a higher risk of complications in the oncoplastic group, these numbers were less clear when looking at specific types of data. Because different clinics report complications differently, these specific safety numbers should be viewed with caution.
