Additional sectioning and AI-assisted diagnosis reveal underdiagnosis of serous (pre)malignancies in fallopian tube specimen from BRCA1/2 carriers
Aim Germline BRCA1/2 pathogenic variant carriers are at increased risk for high-grade serous carcinoma (HGSC) and are therefore advised to have a risk-reducing salpingo-oophorectomy (RRSO) around the age of 40. A risk of 0.9% to develop peritoneal HGSC (pHGSC) remains, which increases up to 27.5% when serous tubal intraepithelial carcinoma (STIC) is detected at RRSO. The relationship between the detection of STIC and the occurrence of pHGSC is still poorly understood. Here, we investigated the role of tissue sam…
Additional sectioning at 150 μm intervals with deep learning support detected isolated STIC or HGSC in BRCA1/2 carriers whose initial RRSO pathology was negative but who later developed peritoneal HGSC.
Standard initial pathology of RRSO specimens missed serous (pre)malignancies in BRCA1/2 carriers, leaving occult STIC or HGSC undetected in patients who subsequently developed peritoneal HGSC.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-0755 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
