ABSTRACT
Objective: To study the clinicopathological characteristics,diagnosis,multiple modality therapy and prognosis of accessory breast cancer. Methods: Clinical data of 38 patients with accessory breast cancer seen in our hospital between October 1985 and November 2007. Results: The 38 cases of accessory breast cancer accounted for 0.15% of all 26,078 breast cancer cases during the same period.Six patients of stage Ⅰ and 3 patients of stage Ⅱ underwent breast-conserving local wide excision of the tumor plus axillary lymph node dissection,with the resection margins pathologically negative.The other 9 cases of stage Ⅱ patients were treated with Auchincloss mastectomy.Stage Ⅲ and stage Ⅳ patients were treated with Auchincloss or Halsted mastectomy.The most common histological type of accessory breast cancer was infiltrating ductal Carcinoma for 18 patients(47.4%),of which 3 cases were associated with adenoma of the nipple tube.There were 6 cases of carcinoma simplex,6 cases of intraductal Carcinoma,3 cases of adenocarcinoma with focal squamous cancer cells differentiation,3 cases of medullary carcinoma,and 2 cases of mucinous adenocarcinoma.The most common pathological stages(according to AJCC staging of breast cancer,2002.6th edition)were stage Ⅱ and Ⅲ in 12 cases(31.6%),stage Ⅰ in 6 cases,and stage Ⅳ in 8 cases.All patients were followed-up for 1 to 23 years.The median follow-up time was 6 years and 7 months,and the follow-up rate was 100%.Until November 2008,12 patients died of metastasis and the other 26 patients were still alive.The 5-year overall survival rate was 35.3%.significantly lower than that of breast cancer patients(66.8%).The 3-year survival rate was 77.8%.The 5-year disease free survivaI rate was 28.6%and the 3-year disease free survival rate was 63.6%. Conclusion: Accessory breast cancer is rarely seen but is aggressive.The diagnosis mainly depends on clinical characteristics,postoperative pathology and imaging examinations.Early diagnosis is essential.Surgery combined with other adjuvant therapies can improve patient survival.
