A254 SYNCHRONOUS GASTRIC ADENOCARCINOMA, MUCOSA-ASSOCIATED LYMPHOID TISSUE LYMPHOMA AND GASTROINTESTINAL STROMAL TUMOR.
Bibliographic record
Abstract
Presently, there is very little literature on the simultaneous existence of different types of gastric cancers. We present a case of rare concomitant cancers (adenocarcinoma, mucosa-associated lymphoid tissue lymphoma and gastrointestinal stromal tumor) in the stomach. It is important for clinicians to be aware of the various presentations of gastric cancers, as it may alter the treatment and prognosis. This is a case report. We present the case and histology of a H. pylori negative 70-year-old man with concomitant adenocarcinoma, mucosa-associated lymphoid tissue lymphoma (MALT) and gastrointestinal stromal tumor of the stomach who was successfully treated with total gastrectomy and oesophago-jejunostomy Roux-en-Y anastomosis. Although H. pylori seems to play an important role in the pathogenesis of gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma (MALT), its role in the carcinogenesis of gastrointestinal stromal tumors is still unknown. In addition, the link between these tumours becomes more complex in H. pylori negative patients. Many authors have argued that the discovery of synchronous neoplasms in a single tissue is coincidence. It is for this reason that some physicians may underreport the incidence of concomitant tumours. It is important for clinicians to be aware of the various presentations of gastric cancers, as it may alter the treatment and prognosis. None

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.
