Correlations of Galectin-3 Gene Polymorphisms with Risk and Prognosis of Cervical Cancer in Chinese Populations: A Case-Control Study

Background: This study explores correlations of galectin-3 gene polymorphisms (rs4644, rs4652, and rs11125) with cervical cancer risk and prognosis in Chinese populations. Methods: A total of 126 patients with cervical cancer were selected to form the case group, and 102 healthy people were selected for the control group following a physical examination. 3 polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The distribution frequencies of the CC+CA genotype of rs4652 and the AT+TT genotype of rs11125 in the case group were remarkably higher than those in the control group. rs4644 only had correlations with tumor diameter, while rs4652 and rs11125 had correlations with tumor diameter, FIGO staging, differentiation grades, clinical staging, lymph node metastasis (LNM), and treatment modality. The 5-years survival rate of patients with CC+CA of rs4652 was lower but the recurrence rate was higher compared to AA type patients. In contrast, AA type patients with rs11125 had a higher 5-year survival rate but a lower recurrence rate than those of AT+TT type. CC+CA genotype of rs4652, AT+TT genotype of rs11125, and treatment modality were independent factors related to overall survival and disease-free survival, and LNM was an independent factor related to OS. Conclusion: Our findings provide evidence that allele C of rs4652 and allele T of rs11125 in the galectin-3 gene may be risk factors for cervical cancer.
