Cervical Gastric-type Adenosquamous Carcinoma: Case Report of a Rare Neoplasm Associated With a BRCA1 Pathogenic Variant
Bibliographic record
Abstract
Gastric-type adenocarcinoma is the commonest human papillomavirus (HPV)-independent adenocarcinoma of the cervix. We report a rare case of a primary cervical gastric-type adenocarcinoma with malignant squamous elements (gastric-type adenosquamous carcinoma) in a 64-yr-old female. This is only the third report of a cervical gastric-type adenosquamous carcinoma. The tumor was p16 negative and molecular studies for HPV were negative. Next-generation sequencing showed pathogenic variants in BRCA1 and KRAS , as well as variants of unknown significance in CDK12 and ATM and homozygous deletion of CDKN2A/CDKN2B . Pathologists should be aware that not all cervical adenosquamous carcinomas are HPV-associated and the term gastric-type adenosquamous carcinoma is recommended when malignant squamous elements are present within a gastric-type adenocarcinoma. In reporting this case, we discuss the differential and the possible therapeutic options raised by the presence of pathogenic variants in BRCA1 .

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
