A survey of preventive measures among<i> BRCA1 </i>mutation carriers from Poland
Bibliographic record
Abstract
Among women with a BRCA1 mutation, the lifetime risks of breast and ovarian cancer are elevated. Several measures for reducing cancer risk in carriers of BRCA1 mutations have been proposed, including prophylactic surgery and tamoxifen chemoprevention. It is not yet known to what extent women with mutations have adopted these various preventive measures. We surveyed 414 Polish women with a BRCA1 mutation who had received counseling about various preventive strategies. Each woman completed a survey for a minimum of 18 months after receiving her genetic result. A high proportion of women reported having had an oophorectomy to reduce breast and ovarian cancer risk (49.1%). In contrast, only 11% had taken tamoxifen and only 5% had undergone a preventive mastectomy. Most of the women (81%) had a screening mammogram during the follow-up period. Oral contraceptives and breastfeeding are believed to protect against ovarian cancer, but only 9% of women had taken the birth control pill for 3 years or more and 27% had breastfed for 1 year or more. In summary, approximately one-half of Polish women with a BRCA1 mutation had taken an active step to reduce their risk of breast cancer within 18 months of receiving a positive result. A greater effort should be made to promote breastfeeding and use of oral contraceptive as risk-reducing measures.

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.
