Rates of risk‐reducing surgery in Israeli <i><scp>BRCA1</scp></i> and <i><scp>BRCA2</scp></i> mutation carriers
Bibliographic record
Abstract
The frequency of BRCA1 and BRCA2 mutations is higher in Israel than in almost all other countries. One strategy to reduce the burden of hereditary breast and ovarian cancers is to offer genetic testing followed by risk-reducing surgery (mastectomy and salpingo-oophorectomy) for mutation carriers. The extent to which Israeli women who carry mutations undergo these surgeries is not well characterized. Israeli women who are BRCA1 or BRCA2 mutation carriers and followed at a single high-risk clinic were asked to complete a questionnaire detailing their clinical histories at the time of genetic results disclosure and a follow-up questionnaire was completed 18 or more months thereafter. A total of 205 mutation carriers completed the questionnaires. Of 170 women with no cancer history, 84 (49%) had a risk-reducing bilateral salpingo-oophorectomy and 22 (13%) had a risk-reducing mastectomy. Five of 35 (14.3%) women with breast cancer opted for contralateral mastectomy. Approximately one half of Israeli women with a BRCA1 or BRCA2 mutation opt for risk-reducing oophorectomy, but the rate of risk-reducing mastectomy is only 13%.

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.
