Oesophagus Including Oesophagogastric Junction
Bibliographic record
Abstract
Abstract Carcinoma of the oesophagus has undergone a major modification between the 6th and 7th TNM editions: T1 and T4 are subdivided to provide greater detail for imaging and management; regional lymph nodes (N) are subdivided by number involved rather than by their location; distant metastasis (M) has been simplified to M1 rather than subdivided by location. Stage grouping has been divided into: 1) purely anatomical stages applicable to all types of carcinomas; and 2) prognostic groups that separate squamous from adenocarcinoma and add grade and tumour location to the T, N, and M elements. The first approach preserves the pure anatomic extent of disease concept and allows direct stage by stage comparisons of behaviour between tumours of different histological types and location; the second recognizes the prognostic influence of grade and tumour location. The use of the terms Stage grouping and Prognostic grouping distinguishes the two. The staging of carcinomas of the oesophagogastric/gastroesophageal junction has been addressed and the definition is noted in the oesophagus and stomach chapters.

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.
