Early Detection of Metasteses in Colorectal Cancer With an Intensive Radiological Follow Up
Bibliographic record
Abstract
Methods: Data was collected between January and December 2008.Patients with rectal bleeding referred to the nurse led endoscopy list were analysed.Results: 76 patients under the age of 40 were identified from the list.Male to female ratio was 42:34.The mean age of the study group was 30.2 (Range17.1-39.9)years.Haemorrhoids were most common endoscopic finding in 47 out of 76 patients (62%), followed by colitis in 9(12%), which was histologically confirmed.Anal fissure was identified in 8(11%) patients while 7 patients (9%) were found to have adenomatous polyps needing further colonoscopy.5 patients were reported to have normal sigmoidoscopy.Conclusions: 21% of the patients under 40 had either histologically confirmed colitis or adenomatous polyps requiring further assessment.Although studies suggest that flexible sigmoidoscopy under 40 years has low diagnostic yield for cancer there is still a role for it in identifying early adenomatous lesions and diagnosis of colitis.Larger studies are necessary to substantiate these results.

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.
