Breast Cancer and Secondary Cancer Recurrences After Autologous Tissue Reconstruction

A 20-year retrospective review of locoregional recurrences, secondary cancers, and atypical breast neoplasms after autologous tissue reconstruction for cancer of the breast identified an overall recurrence rate of 5.3%. The rate for secondary cancers was 1.2%. Survival rates after treatment for breast carcinomas were concordant with those reported in the literature. We report treatment and survival data for secondary cancers. Background: The medical literature defining breast cancer recurrence and secondary cancers after autologous tissue reconstruction for breast cancer is sparse. We sought to identify and analyze occurrences at our institution. Patients and Methods: A 20-year retrospective review of cancer recurrences and atypical breast neoplasms after autologous tissue breast reconstruction at Roswell Park Comprehensive Cancer Center was conducted after being granted a waiver from the institutional review board. Results: Eighteen locoregional recurrences among 337 cases were identified and analyzed. Overall recurrence rate was 5.3%. Four secondary cancers (1.2%) were radiation-induced angiosarcoma, undifferentiated pleomorphic sarcoma, and metaplastic carcinoma. One case of flat epithelial atypia was identified. Conclusion: Our retrospective review found incidence and survival after treatment of breast cancer concordant with reports in the literature. We also identified and analyzed secondary neoplasms, including a unique case of undifferentiated pleomorphic sarcoma and metachronous recurrence of breast carcinoma. A case of recurrence as metaplastic carcinoma was identified. (C) 2020 Elsevier Inc. All rights reserved.
