Abstract
Objective: To explore the oncological safety of immediate breast reconstruction after nipple-areola complex(NAC) sparing mastectomy(NSM+ IBR) in patients with early stage breast cancer, and to analyze the prognostic factors of NSM+ IBR. Methods: From January 2004 to December 2015, the clinical data of 118 cases of stage Ⅰ-ⅡA breast cancer who had undergone NSM+ IBR in Tianjin Tumor Hospital were collected, comparing with 75 cases of Ⅰ-ⅡA breast cancer patients who had undergone immediate breast reconstruction after modified radical mastectomy (MRM+ IBR) at the same period. In addition to the prognosis of these two groups, the prognostic factors were also retrospectively analyzed. Results: The median follow-up were 53 months in the NSM+ IBR group and 51 months in the MRM+ IBR group, respectively. In the NSM+ IBR group, local recurrence, distant metastasis, death and NAC necrosis occurred in 4, 6, 9 and 4 cases during 3 years after operation, respectively. The local recurrence rate (LRR) was 3.4%, 3-year disease-free survival (DFS) rate was 91.5%, and the overall survival (OS) rate was 92.4%. In the MRM+ IBR group, local recurrence, distant metastasis, and death occurred in 1, 4, and 3 cases during 3 years after operation, respectively. The LRR was 1.3%, 3-year DFS was 93.3%, whereas the OS rate was 96.0%. No statistical difference was noted between the two groups (all P>0.05). That HER-2 positive and molecular type correlated with the 3-year DFS (P<0.05) independently and molecular type correlated with OS (P<0.05) independently in the NSM+ IBR group. Conclusions: NSM does not impair patients' prognosis and could ensure oncological safety of patients with early stage breast cancer. IBR could improve female patients' figure and ensure the quality of life. HER-2 status and molecular type are the independent prognostic factors of the 3-year DFS. Molecular type is the independent prognosis factor of OS.
