Abstract

fetched live from OpenAlex

Primary malignancies of the appendix are rare. Of these, less than 5% are goblet cell carcinoid (GCC) tumours. The majority of GCC present with findings of acute appendicitis or advanced peritoneal spread. We describe a rare presentation of GCC as subtle mucosal abnormality of the appendiceal orifice seen on colonoscopy performed for iron-deficiency anaemia. Biopsies were interpreted as adenocarcinoma; however, final surgical pathology confirmed GCC of the appendix with caecal involvement. The patient recovered well from surgery, anaemia resolved and follow-up did not show metastatic disease.

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.

Not 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.
