High Prevalence of the BIM Deletion Polymorphism in Young Female Breast Cancer in an East Asian Country.

ABSTRACT:

Background

A rapid surge of female breast cancer has been observed in young women in several East Asian countries. The BIM deletion polymorphism, which confers cell resistance to apoptosis, was recently found exclusively in East Asian people with prevalence rate of 12%. We aimed to evaluate the possible role of this genetic alteration in carcinogenesis of breast cancer in East Asians.

Method

Female healthy volunteers (n = 307), patients in one consecutive stage I-III breast cancer cohort (n = 692) and one metastatic breast cancer cohort (n = 189) were evaluated. BIM wild-type and deletion alleles were separately genotyped in genomic DNAs.

Results

Both cancer cohorts consistently showed inverse associations between the BIM deletion polymorphism and patient age (≤35 y v
