Life style, environmental and genetic susceptibility to cervical cancer.
We have studied cervical cancer (CC) patients from Venezuela and the US to elucidate the contribution of certain acquired and genetic susceptibility factors to the development of the disease. For acquired susceptibility factors, infection with high risk human papilloma virus (HPV), having multiple sex partners and having early sexual activities are significant risk factors for CC in Venezuela. The latter two are not significant risk factors for the US population. Infection with high risk HPV is a more significant risk factor for the US than the Venezuela populations. On the other hand, cigarette smoking is significantly associated with CC in the US but not the Venezuela populations. From genetic susceptibility factors, polymorphisms in the CYP2E1 and mEH genes are not associated with CC but the GSTM1 null genotype is for the US population. Our study indicates that the same susceptibility factors can have very different roles in the development of the same disease such as CC in different countries. The information is useful for the development of effective but different disease prevention programs for different countries in the control of CC.
