摘要

Objective.

In this study, genetic polymorphisms, XRCC1 Arg399Gln and OGG1 Ser326Cys were examined with reference to cervical cancer risk in a population-based incident case-control study in Japan.

Methods.

The cases comprised 131 cervical cancer patients: 87 cases with squamous cell carcinoma (SCC) and 44 with adenocarcinoma (ADC) or adenosquamous carcinoma (ADSC). Controls were sampled from 320 healthy women who underwent a health checkup.

Results.

The frequency of the XRCC1 399GlnGln genotype was higher in individuals with adenocarcinoma/adenosquamous carcinoma than in the healthy controls (OR = 2.98, 95%CI = 1.11–8.01, P = 0.030). However, no association was demonstrated in SCC. Analysis of OGG1 Ser326Cys polymorphism showed no significant differences between cervical cancer patients and controls. In stratification analysis, significant elevated risk of adenocarcinoma/adenosquamous carcinoma was associated with the XRCC1 399GlnGln genotype among nonsmokers (OR = 3.85, 95%CI = 1.28–11.59, P = 0.017), but not among smokers. No gene–gene interaction was observed in our case subjects.

Conclusion.

This is the first report that the XRCC1 Arg399Gln polymorphism might be important in relation to the risk of adenocarcinoma/adenosquamous carcinoma of the cervix.
