Abstract
Objective
To determine the incidence of serous tubal intraepithelial carcinoma (STIC) after risk reduction salpingo-oophorectomy(RRSO), and to describe oncological outcomes after RRSO.
Materials and methods
BRCA pathogenic mutation carriers who had undergone an RRSO were evaluated in this retrospective multicenter observational study. Patients were only included when fallopian tubes were analyzed following the protocol for Sectioning and Extensively Examining the FIMbria (SEE-FIM). Surgeries were performed between June 2010 and April 2017 at eight Spanish hospitals.
Results
A total of 359 patients met the inclusion criteria. STIC was diagnosed in 3 (0.8%) patients; one of them underwent surgical staging due to positive peritoneal washing, with absence of disease at the final pathology report. None of the three patients received adjuvant chemotherapy and were free of disease at last follow-up. Fallopian tube and ovarian carcinoma were diagnosed in 5 (1.4%) and 1 (0.3%), respectively. At a median (range) follow-up time of 29 (3–92) months, five patients had a newly diagnosed breast cancer. Other types of cancer, which were diagnosed during the follow-up time, included: serous primary peritoneal carcinoma (n = 1), serous endometrial carcinoma (n = 1), colon (n = 1), pancreas (n = 1), jaw (n = 1), and lymphoma (n = 1). Seven patients died due to different types of cancer: breast (n = 4), pancreas (n = 1), jaw (n = 1), and colon (n = 1).
Conclusion
The incidence of STIC after RRSO in BRCA mutation carriers is low (0.8%) and it presents an excellent oncological outcome. Patients after RRSO, however, run the risk to develop other types of cancer during follow-up and should be properly advised before the prophylactic surgery.
