Summary
Oncoplastic breast conserving surgery (OPS) improves aesthetic outcomes and patient satisfaction. Standardized algorithms for OPS indications and reconstruction enhance surgical planning and outcomes, showing comparable recurrence rates to conventional methods.
Area of Science:
- Oncologic surgery
- Plastic and reconstructive surgery
- Breast cancer treatment
Background:
- Growing emphasis on aesthetic outcomes and quality of life post-breast cancer surgery.
- Limited standardization and training programs challenge scientific evaluation of oncoplastic breast conserving surgery (OPS).
Purpose of the Study:
- To standardize OPS nomenclature, indications, and reconstruction techniques through a comprehensive literature review.
- To introduce algorithms for tailored surgical planning in OPS.
Main Methods:
- Categorization of breast conserving surgery (BCS) into four types: Conventional tumorectomy, oncoplastic mastopexy, oncoplastic tumorectomy, and oncoplastic reduction mammoplasty.
- Review of volume displacement techniques including glandular re-approximation, flaps, and nipple-areola complex pedicles.
- Development of algorithms for indication and reconstruction selection based on breast/tumor characteristics and vascular supply.
Main Results:
- Proposed algorithms aid in selecting appropriate OPS techniques for individual patients.
- OPS demonstrates comparable local recurrence rates to conventional BCS.
- OPS achieves higher rates of clear resection margins, even for larger tumors.
- Improved aesthetic outcomes and patient satisfaction reported with OPS.
Conclusions:
- Standardized algorithms facilitate consistent and individualized OPS.
- OPS offers oncological safety with enhanced aesthetic results and patient satisfaction.
- OPS represents a significant advancement in breast cancer surgery, optimizing outcomes.
