Impact of gynecological screening in Lynch syndrome carriers with an <i>MSH2</i> mutation
Bibliographic record
Abstract
Lifetime risk of developing endometrial cancer in Lynch syndrome carriers is very high and females are also at an increased risk of developing ovarian cancer. The aim of the study was to determine the impact of gynecological screening in MSH2 mutation carriers. Gynecological cancer incidence and overall survival was compared in female mutation carriers who received gynecological screening (cases) and in matched controls. Controls were randomly selected from non-screened mutation carriers who were alive and disease-free at the age the case entered the screening program. Median age to diagnosis of gynecological cancer was 54 years in the screened group compared to 56 years in controls (p = 0.50). Stage I or II cancer was diagnosed in 92% of screened patients compared to 71% in the control group (p = 0.17). Two of three deaths in the screened group were the result of ovarian cancer. Mean survival in the screened group was 79 years compared to 69 years in the control group (p = 0.11), likely associated with concomitant colonoscopy screening. Gynecological screening did not result in earlier gynecologic cancer detection and despite screening two young women died from ovarian cancer suggesting that prophylactic hysterectomy with bilateral salpingo-oophorectomy be considered in female mutation carriers who have completed childbearing.

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.
