Mucinous carcinoma in Crohn’s disease originating in a fistulous tract
Bibliographic record
Abstract
Malignant disease, including mucinous carcinomas of the colorectum, may complicate long-standing Crohn's disease. An 18-year-old male with extensive small and large bowel involvement with Crohn's disease developed recurrent peri-rectal fistulous disease that persisted for more than a decade despite pharmacological and surgical therapy as well as later therapy with biological agents. Eventually, an extensive and difficult-to-detect mucinous carcinoma developed in the fistulous tract. Although fistula cancer is rarely described in Crohn's disease, use of immunosuppressant and biological agents may play an initiating or exacerbating role in its development or progression. As potent biological agents are frequently used, often to avoid surgical treatment, clinicians should have an increasingly high index of suspicion for this potential complication, especially if fistulous drainage persists and remains refractory to medical therapy.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
