Expanding Growth and Pharyngeal Mass Formation in Elderly Patient With Esophageal Cancer: Unusual Manifestation
Bibliographic record
Abstract
sophageal squamous cell carcinoma has invasive nature itself, and infiltration to the surrounding organs is common. We experienced a case of esophageal cancer with unusual manifestation. Eighty-one-year-old female with 3 years history of cognitive disorder referred to our hospital because of dysphagia lasting for a month. The upper gastrointestinal endoscopy with thin scope revealed a white-colored, soft mass lesion occupying almost whole of the lower pharynx. The lesion connected to the thickened esophageal wall, and the scope could not get through due to stenosis at the upper esophagus. The computed tomography showed marked thickness of the esophageal wall at the upper to middle portion without direct invasion or fistula formation to the surrounding organs. The lesion had protruding parts at the both edges, shown as low-density area on computed tomography, indicating inflammatory change. Pathological examination of the biopsied specimen showed squamous cell carcinoma of the esophagus and necrotic tissue of the pharynx. The patient initiated radiation therapy after tracheotomy was made, but died due to pneumonia two months later. doi:10.4021/jmc587w

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.
