Clinical significance of isolated tumor cells and micrometastasis in low‐grade, stage I endometrial cancer
Bibliographic record
Abstract
Introduction Ultrastaging in endometrial cancer (EC) led to increased detection of isolated tumor cells (ITC, ≤0.2 mm) and micrometastases (MM, 0.2‐2 mm), with unclear effect on prognosis. Our aim was to characterize the impact of ITC and MM on the outcome of these patients. Methods Grade 1 to 2 stage I endometrioid EC patients with nodal ITC ( n = 11) or MM ( n = 12) between 2012 and 2018 were retrospectively compared to a matched group of lymph node negative ( n = 18) patients based on age, body mass index, grade, myometrial invasion, and lymphovascular space invasion (LVI) status using propensity score analysis (1:1). Mann‐Whitney U tests were performed on continuous variables and χ 2 tests on categorical variables. Progression‐free survival (PFS) was the main endpoint. Results All MM and 81% of ITC had LVI. More ITC/MM patients received RT and chemotherapy (91.7% vs 18.4%; 70.8% vs 4.5%, respectively; P < 0.01) without significant difference in treatment‐related toxicities (25% vs 27.3% grade 1%‐2% and 20.8% vs 9.1% grade 2‐3; P = 0.538) or PFS (29.2 vs 25 months; P = 0.828). Two distant recurrences occurred in MM patients after 2.5 years; one lung and one para‐aortic lymph node. Conclusion With adjuvant treatment, ITC/MM in otherwise well‐differentiated stage I endometrial cancer have similar outcomes to matched LN− patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
