Abstract

Micro-Abstract

Although volume displacement procedures after partial mastectomy for breast cancer are increasingly being performed, few studies have comprehensively reported the oncologic outcomes of these procedures and the associations of those outcomes with clinicopathological variables. This study addresses that deficit in part and presents data concerning the efficacy of these procedures.

Background:

Volume displacement techniques that use remnant breast tissue are useful in reconstructive procedures after partial mastectomy. The authors analyzed the oncologic results of volume displacement surgery after partial mastectomy and their associations with various clinicopathologic factors.

Patients and Methods:

One hundred fifty-eight eligible patients with breast cancer who underwent volume displacement procedures after partial mastectomy were included in this prospective study, in which associations between clinicopathologic factors and locoregional recurrence, distant metastasis, and death were analyzed.

Results:

During a mean follow-up of 60.8 months, locoregional recurrence occurred in 3 cases (1.9%) and distant metastasis in 4 (2.5%). According to multivariate analysis, bilaterality of breast cancer (P = .035) and adjuvant chemotherapy (P = .042) were associated with distant metastasis.

Conclusion:

Volume displacement procedures after partial mastectomy have good oncologic results and are acceptable procedures for patients with breast cancer.
