The Use of 18F-FDG PET/CT in Cowden Syndrome to Differentiate Multifocal Gastric Carcinoma From Extensive Benign Gastric Polyposis
Bibliographic record
Abstract
A 73-year-old man suffering from Cowden syndrome with gastrointestinal polyposis was referred for an 18F-FDG PET/CT after a routine gastroscopic biopsy revealed a poorly differentiated adenocarcinoma. The 18F-FDG PET/CT identified 2 foci of FDG-avid gastric adenocarcinoma on the background of extensive gastric and colorectal polyposis, and correctly staged the disease, which guided management toward a total gastrectomy. This rare case highlights the usefulness of 18F-FDG PET/CT in the staging of gastric malignancy in Cowden syndrome.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
