Primary Ewing Sarcoma of the Stomach
Bibliographic record
Abstract
To the EditorEwing sarcoma (ES), a malignant tumor of small round blue cells, arises usually in skeletal tissues and lacks neuroectodermal differentiation [1].It was reported firstly by James Ewing in 1921.Although previously regarded as a separate entity from primitive neuroectodermal tumor (PNET), which exhibits neuroectodermal features, nowadays, they are treated as the same tumor due to the similarity in chromosomal translocation and immunohistochemical characteristics [1].These tumors belong to the ES family of tumors which include skeletal ES/ PNET, extraskeletal ES/PNET and Askin tumor (thoracopulmonary PNET).These tumors originate from distinctive mesenchymal progenitor cells due to their similar histologic and immunohistochemical characteristics.ES is a highly metastatic type of sarcoma and represents almost 10-15% of bone sarcomas, and is regarded as the second most common primary malignant bone tumor [2].Although 5-year survival and overall survival have been improved significantly recently, the recurrence rate of such tumors remains high.

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.
