Human Papillomavirus-Related Ovarian Metastasis With Endocervical Adenocarcinoma
Bibliographic record
Abstract
BACKGROUND: Most endocervical adenocarcinomas are associated with human papillomavirus (HPV) infection. Studies suggest that synchronous endocervical and ovarian tumors can contain identical HPV subtypes and that, in this setting, the ovarian tumors likely represent metastases from the endocervical adenocarcinoma rather than 2 independent primaries. However, there are still relatively few reports in the literature. RESULTS: We describe 2 patients with HPV-related endocervical adenocarcinoma or adenocarcinoma in situ who had metastatic ovarian tumors that simulated primary ovarian neoplasms. After total hysterectomy and bilateral salpingo-oophorectomy, patient 1, in her mid-40s, was diagnosed with endocervical adenocarcinoma in situ and patient 2, in her early 50s, was diagnosed with endocervical adenocarcinoma showing early focal stromal invasion. The ovarian tumors in both cases simulated independent borderline mucinous tumors without evidence of surface involvement or spread beyond the ovary. However, in both cases, the cervical and ovarian tumors showed diffuse, strong P16 staining and contained identical high-risk HPV subtypes (subtypes 16 and 18 in patient 1 and subtype 16 in patient 2). Patient 1 was treated with radiation therapy and remains recurrence free 5 years after diagnosis, and patient 2 has recently completed combined modality treatment with radiation therapy and cisplatin chemotherapy and remains recurrence free 10 months after diagnosis. CONCLUSIONS: A high index of suspicion and ancillary testing, including P16 immunostaining and molecular genetic testing for HPV, is required to properly diagnose and subclassify HPV-related endocervical adenocarcinoma metastatic to the ovary.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
