These encouraging results are in line with those of Lee et al., who did not observe an increase in serous or endometrioid endometrial cancer in their small Australasian population, and Levine et al., who reported a relative risk of endometrial cancer of 0.75 (95% CI = [0.24, 2.34], p = 0.6) in 199 Ashkenazi Jews with BRCA1/2(BRCA1 SIR = 2.87, 95%CI = [0.59,8.43], p = 0.18 / BRCA2 SIR = 2.01, 95%CI = [0.24,7.30], p = 0.52) [22]. This evidence concerns the gene BRCA1 and endometrial cancer.
