Endometrial stromal sarcoma – the new genetic paradigm
Bibliographic record
Abstract
Endometrial stromal sarcoma (ESS) is a gynaecological sarcoma that is composed of cells that resemble those of proliferative-phase endometrial stroma. The 2014 World Health Organization tumour classification system separates ESS into low-grade and high-grade types, which are histologically, genetically and clinically distinct from undifferentiated uterine sarcoma (UUS). Low-grade ESSs frequently contain chromosomal rearrangements that result in JAZF1-SUZ12 fusion or equivalent genetic fusions. Although most low-grade ESSs show classic histological features that closely resemble those of proliferative-phase endometrial stroma, there are several histological variants that are associated with the same genetic fusions as seen in the classic type. High-grade ESS is defined by the presence of YWHAE-NUTM2A/B (YWHAE-FAM22A/B) fusions. High-grade ESSs are clinically more aggressive than low-grade ESSs, but are associated with a lower mortality rate than UUSs. The histological and immunophenotypic features of these different types of ESS, and their diagnostic considerations, are the subjects of this review.

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.
