A meta-analysis comparing breast conservation therapy alone to the oncoplastic technique

Area of Science:

• Oncology
• Plastic Surgery
• Breast Surgery

Background:

• Breast conservation therapy (BCT) is a standard treatment for breast cancer.
• Immediate reconstruction in BCT can improve cosmetic outcomes beyond initial expectations.

Purpose of the Study:

• To compare outcomes between BCT alone and BCT with an oncoplastic approach.
• To evaluate the oncologic and aesthetic results of oncoplastic breast surgery.

Main Methods:

• A meta-analysis was conducted using PubMed, searching for "oncoplastic," "partial breast reconstruction," and "breast conservation therapy."
• Studies with less than 10 patients or under 1-year follow-up were excluded.
• Three groups were compared: BCT with oncoplastic reduction, BCT with oncoplastic flaps, and BCT alone.

Main Results:

• The oncoplastic group (3165 patients) showed a significantly lower positive margin rate (12% vs. 21%) compared to BCT alone (5494 patients).
• Re-excision was more common in the BCT alone group (14.6% vs. 4%), but completion mastectomy was more frequent in the oncoplastic group (6.5% vs. 3.79%).
• Patient satisfaction with aesthetic outcomes was significantly higher in the oncoplastic group (89.5% vs. 82.9%).

Conclusions:

• The oncoplastic approach facilitates wider tumor resection, leading to reduced positive margins in BCT.
• While local recurrence requires further investigation, oncoplastic surgery significantly enhances patient satisfaction with cosmetic results.
