Lymphotoxin-α polymorphism and the risk of cervical cancer in Japanese subjects

To examine the possible association between cervical cancer and Lymphotoxin-α (LTα) polymorphisms, C804A and A252G, an incident case-control study was conducted in Japanese. The cases were 131 cervical cancer patients. Controls were 320 healthy women. Risk estimation was conducted by an unconditional logistic model. Complete linkage disequilibrium was seen between LTα C804A and LTα A252G. We found that, compared with the 804CC genotype, 804CA and 804AA were associated with a decreased risk of cervical cancer (OR=0.64, 95% CI=0.40-1.02; and OR=0.45, 95% CI=0.21-0.95, respectively), especially of SCC (OR=0.54, 95% CI=0.32-0.91; and OR=0.39, 95% CI=0.16-0.92, respectively).
