Development of testicular germ cell cancer following successful infliximab induction therapy for ulcerative colitis
Bibliographic record
Abstract
Antitumor necrosis factor alpha (anti-TNFα) agents have substantially altered the management of inflammatory bowel diseases (IBD). Their benefits must however be weighed against increased risks for infections, lymphoma, and possibly other malignancies. We report on a 27-year-old man, with a six-year history of ulcerative colitis maintained on mesalamine suppositories, presenting with clinical, radiographic and biopsy evidence of an acute colitis flare. Due to the refractory nature of his disease, infliximab was started, resulting in induction of remission within six weeks. Three months after the first dose of infliximab, the patient was diagnosed with a testicular mixed germ cell tumor requiring orchiectomy. Four cases of testicular cancer development among patients using anti-TNFα agents have been identified. Given the prevalence of IBD in young men and recent suggestions for "top-down therapy," testicular cancer as a potential complication of anti-TNFα agents should be further explored on a population basis.

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.
