| Research Abstract |
We analyzed 56 single nucleotide polymorphisms (SNPs) identified in previous GWASs and conducted a case-control study with 697 case subjects and 1,394 age- and menopausal status-matched controls within the framework of Hospital-based Epidemiological Research Program at Acihi Cancer Center. Among 56 SNPs, 23 was selected to built a risk prediction model for breast cancer. We evaluated the prediction models using AUC (Area Under the Curve) in receiver-operating characteristic (ROC). The AUC for a model including the genetic risk score in addition to the conventional risk factors was 0.726, versus 0.675 with the conventional risk factors only (P <0.05). In conclusion, we identified a genetic risk predictor of breast cancer in a Japanese population. Identification of additional new loci in the GWASs among Asian or Japanese populations is needed to establish more accurate risk prediction model.
