BackgroundIntracystic papillary carcinoma (IPC) is a rare breast neoplasm. There are few studies focusing on its clinical features and limited data about its preoperative diagnosis,treatment and outcomes. The purpose of this study is to explore specific characteristics of patients with IPC, investigate its clinicopathological features, prognosis in China and confirm its surgery management.MethodsWe identified 111 patients with IPC from the registry of Tianjin Medical University Cancer Institute and Hospital between 2004 and 2017. Follow-up of cases dating back to January 1, 2004 was obtained from retrospective chart review and patient questionnaires. Differences in clinical features and survival of patients were assessed using the Kaplan-Meier method.ResultsThe median tumor size was 2.25 cm. Median age was 62 years. In the cases of axillary lymph node dissection(ALND), only 1.1% (1/85) of patients with axillary lymph node metastasis were found. The diagnostic accuracy of preoperative Color Doppler ultrasound and Mammograms for IPC was 62.0% (62/100) and 63.5% (54/85) respectively. The median follow-up period was 52 (range2–149) months. The overall survival rate was 98.9%, 92.2%,and 85.6% at 2,5,and 10 years and the relapse-free rate was 99.1%,97.2%,and 92.0% at 2,5, and 10 years, respectively. The disease-specific survival rate was 100%.ConclusionOverall, we report some unique features of IPC in the Chinese population. The patients of IPC of the breast in China have more excellent prognosis than in Caucasian and other races. The diagnostic accuracy of imaging was low, and was easily misinterpreted as a cyst or benign disease. Preoperative core needle biopsies are very difficult for accurate pathological diagnosis of IPC. IPC is a localized disease with a low frequency of axillary lymph node involvement, rare distant metastases and excellent survival. The low incidence of axillary lymph node metastasis suggests that quadrectomy + sentinel lymph node biopsy (SLNB) and breast-conserving surgery is recommended for IPC.
