Abstract:
Objective:To investigate the clinicopathologic features and prognostic factors of breast cancer patients with tumor deposits in the ipsilateral axillary region.Methods:We retrospectively analyzed the clinicopathologic data and follow-up results of 155 patients with breast cancer diagnosed for the first time and complicated with tumor deposits in the ipsilateral axillary region in the Department of Thyroid-Breast-Vascular Surgery of Xijing Hospital from January 2008 to September 2018. Kaplan-Meier method was used for survival analysis. Log rank test was used for the univariate analysis of prognostic factors, and Cox regression was used for multivariate analysis.Results:The median disease free survival (DFS), median distant metastasis free survival (DMFS), and median overall survival (OS) of the 155 patients were 52.0 months, 66.6 months, and 102.2 months, respectively. The 5-year and 10-year DFS rates were 45.7% and 23.1%, the 5-year and 10-year DMFS rates were 56.9% and 28.9%, and the 5-year and 10-year OS rates were 79.3% and 46.0%, respectively. Multivariate Cox regression analysis showed that family tumor history ( HR=0.362, 95% CI: 0.140-0.937), clinical T stage (T3: HR=3.508, 95% CI: 1.380-8.918; T4: HR=2.220, 95% CI: 1.076-4.580), estrogen/progesterone receptor status ( HR=0.476, 95% CI: 0.261-0.866), number of tumor deposits ( HR=1.965, 95% CI:1.104-3.500) and neoadjuvant chemotherapy ( HR=1.961, 95% CI: 1.032-3.725) were independent influencing factors for DFS. Molecular subtype [human epidermal growth factor receptor-2(HER-2) positive and hormone receptor negative: HR=7.862, 95% CI: 3.189-19.379], number of tumor deposits ( HR=2.155, 95% CI: 1.103-4.212), neoadjuvant chemotherapy ( HR=5.002, 95% CI: 2.300-10.880) and radiotherapy ( HR=2.316, 95% CI: 1.005-5.341) were independent influencing factors of DMFS. Histological grade ( HR=4.362, 95% CI: 1.932-9.849), estrogen/progesterone receptor expression ( HR=0.399, 95% CI: 0.168-0.945), HER-2 expression ( HR=2.535, 95% CI: 1.114-5.768) and neoadjuvant chemotherapy ( HR=4.080, 95% CI: 1.679-9.913) were independent influencing factors of OS. Conclusions:The presence of tumor deposits weakens the influence of axillary lymph node status and distant metastases on the prognosis of breast cancer patients. Therefore, a clinicopathological staging system taking into account tumor deposits should be developed. Since the number of tumor deposits affects the risk of recurrence and metastasis of breast cancer patients, we recommend that the number of tumor deposits should be reported in detail in the pathological report after breast cancer surgery.
