Abstract:
Objective:To explore the clinicopathological characteristics,diagnosis,treatment and prognosis of accessory breast cancer.Methods:The clinical data were retrospectively analyzed for 17 patients with accessory breast cancer from January 2007 to December 2017,and 85 cases of breast cancer in the same period were randomly selected.Results:17 cases of accessory breast cancer accounted for 0.11% of all 15 500 breast cancer cases during the same period.The median age was 48 years.5 cases were menopause.7 cases had the family history of tumor.6 cases were treated with Auchincloss mastectomy.The remaining patients underwent breast-conserving local wide excision of tumor plus axillary lymph node dissection.The most common histological type of accessory breast cancer was infiltrating ductal carcinoma for 14 patients.There were 3 cases of other types.The most common molecular type of accessory breast cancer was Luminal A for 9 patients,there were 2 cases of Luminal B,2 cases of HER-2,and 4 cases of TNBC.The most common pathological stages ware stage III and stage IV in 12 cases.The 3-year disease-free survival rate (DFS) of the patients with accessory breast cancer was 27.9%,significantly lower than that of breast cancer (P＜0.05).There was no statistical difference between breast cancer with axillary lymph nodes metastasis.Conclusion:The incidence of accessory breast cancer is low,and the location of the disease is hidden.The misdiagnose and the lymph node metastasis are easy to occur,and its prognosis is worse than that of breast cancer.
