Abstract

fetched live from OpenAlex

Despite the worldwide decrease in the incidence of gastric cancer, the proportion of occurrence of carcinomas of the esophagogastric junction and proximal third of stomach is on the rise. The cause of this development is believed to lie in an increasing incidence of reflux esophagitis with Barrett´s metaplasia and successful eradication of Helicobacter pylori infection. The aim of this work is to present various views on the definition of the esophagogastric junction itself and to give an overview of tumor classification schemes being used (Fig. 2, Ref. 54). Keywords: gastric cancer, esophagogastric junction, definition, classification.

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.
