[Don't forget fallopian tubes! A morphologic and immunohistochemical study about Fallopian tubes with genetic risk (BRCA mutation)]

Abstract

Objectives: The objective of this study was to describe morphologic and immunohistochemical features of precursor tubal lesions in prophylactically removed Fallopian tubes.

Patients and methods: Hundred and forty-seven bilateral salpingectomies (genetic predisposition or group A: n=57; and control group or group B: n=90) were reviewed by two pathologists blinded to clinical data. Seven epithelial cytological and architectural features were studied to compare the degree of tubal epithelial abnormalities between the two groups. Immunohistochemical expression patterns of Ki67 and p53 were also evaluated.

Results: Serous tubal intraepithelial lesions (STIL) have been identified in group A with stronger expression for Ki67 and p53 (especially in BRCA 1 group) than in group B.

Discussion and conclusion: The current results show the importance of salpingo-oophrectomy in BRCA mutation carriers and the complete histopathological sampling of the Fallopian tubes.
