Abstract

Background Hereditary breast cancer has been associated with mutations in the BRCA1 and BRCA2 genes and has a natural history different from sporadic breast cancer. We investigated disease-free and overall survival for patients with a proven BRCA1 alteration.Methods We estimated disease-free and overall survival for 49 Dutch patients from 19 consecutive families with a proven specific BRCA1 mutation and one family with strong evidence for linkage to the BRCA1 gene. We compared clinical outcome and data on tumour size, histology, axillary nodal status, contralateral breast cancer, and oestrogen-receptor and progesterone-receptor status with those of 196 patients with sporadic breast cancer, matched for age and year of diagnosis.Findings Disease-free survival for BRCA1 and sporadic patients at 5 years was 49% (95% CI 33-64) and 51% (43-59), respectively (p=0.98). Overall survival at 5 years was 63% (47-76) and 69% (62-76), respectively (p=0.88). Recurrence and death rates did not differ significantly between groups. Hazard ratios for recurrence and death among BRCA1 patients were 1.00 (0.65-1.55) and 1.04 (0.63-1.71) relative to sporadic patients (p=0.88), and these did not differ significantly after adjustment for prognostic factors. Patients with BRCA1-associated breast cancer had twice as many progesterone-receptor-negative tumours (p<0.005) and development of contralateral breast cancer was four to five times as frequent as in the sporadic group (p<0.001).Interpretation We showed that disease-free and overall survival were similar for sporadic and hereditary breast cancer in the presence of different tumour characteristics, which has implications for screening prophylactic therapy, and different treatments of hereditary breast cancer.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
