Background

Therapeutic mammoplasty (therapeutic mammoplasty) is a well-established oncoplastic breast-conserving technique, particularly for patients with large ptotic breasts.

Purpose

This study evaluated the outcomes of therapeutic mammoplasty combined with contralateral reduction mammoplasty in a cohort of East Asians.

Methods

We conducted a single-center retrospective observational study of consecutive patients who underwent therapeutic mammoplasty with simultaneous contralateral reduction mammoplasty for breast cancer between April 2014 and March 2024.

n = 104 patients

Results

most patients had good or excellent cosmetic results

83%

BCCT.core excellent/go

79%

Harvard scale excellen

More results

Positive margins occurred in 5 patients; 4 underwent additional resection and 1 received boost irradiation alone.

Perioperative complications occurred in 27 patients, with 6 requiring reoperation; no cases of nipple necrosis were reported.

Boost irradiation and perioperative chemotherapy were associated with poor cosmetic outcomes.

Conclusion

In selected East Asian patients with relatively large ptotic breasts, therapeutic mammoplasty combined with contralateral reduction mammoplasty demonstrated favorable oncologic safety and cosmetic outcomes.
