Conservative mastectomies like skin-sparing mastectomy (SSM) and nipple-areola complex (NAC)-sparing mastectomy (NSM) offer cosmetic benefits for breast cancer patients. Evidence suggests these techniques maintain oncological safety while improving body image.
Area of Science:
- Oncology
- Plastic Surgery
- Breast Surgery
Background:
- Conservative mastectomy techniques, including skin-sparing mastectomy (SSM) and nipple-areola complex (NAC)-sparing mastectomy (NSM), have gained acceptance for early breast cancer treatment.
- These methods aim for improved aesthetic outcomes and immediate reconstruction post-mastectomy.
Purpose of the Study:
- To investigate the evidence supporting the shift towards conservative mastectomy techniques.
- To evaluate the oncological safety and aesthetic outcomes of SSM and NSM compared to traditional mastectomy approaches.
Main Methods:
- A comprehensive literature review was conducted across multiple databases (Medline, Embase, Cochrane, WHO ICTRP, Clinicaltrials.gov).
- Included randomized controlled trials (RCTs), prospective cohorts, and retrospective series comparing conservative mastectomy techniques with breast-conservative surgery or modified radical mastectomy (MRM).
Main Results:
- The review analyzed 58 studies on NSM and immediate reconstruction and 10 studies on SSM and immediate reconstruction.
- Data on complication rates, NAC necrosis, and local/NAC recurrence were extracted for NSM and SSM.
- While RCTs are limited, available evidence from cohorts and series was synthesized.
Conclusions:
- Conservative mastectomies provide significant psychological advantages, enhancing cosmetic results and maintaining a positive body image.
- These techniques do not compromise the oncological safety typically associated with mastectomy for early-stage breast cancer.
- Further RCTs are recommended to strengthen the evidence base for conservative mastectomy approaches.
