Evaluation of the Association between Genetic Polymorphism of Interleukin-1 Beta (-511C/T and +3953C/T) and Cervical Cancer Susceptibility.

Cervical cancer (CC) is the leading cause of cancer-related mortality among women, primarily caused by persistent human papillomavirus (HPV) infection, especially in developing countries. A proinflammatory cytokine, emerging as a major facilitator of carcinogenesis, is termed interleukin-1 beta (IL-1β), which characterizes host-environment interactions. Numerous epidemiological studies have revealed that IL-1β gene polymorphisms have been associated with numerous malignancies, but in the context of CC, results of these studies were inconclusive. Thus, our study aimed to explore the relationship between IL-1β polymorphisms (-511C/T and +3953C/T) and CC susceptibility. Genotyping was conducted on 192 CC patients and 200 healthy controls through polymerase chain reaction-restricted fragment length polymorphism. HPV analysis was done through real-time polymerase chain reaction, and the serum concentration of IL-1β was measured by enzyme-linked immunosorbent assay. Women with CT and TT genotypes of IL-1β -511C/T had a threefold increased risk of CC (odds ratio [OR], 3.60; 95% confidence interval [CI], 2.132-6.063;
