OBJECTIVE: To investigate the incidence of hepatocellular carcinoma (HCC) in Chengdu, identify the risk factors for the development of HCC in Chengdu and provide a reference for the prevention of HCC.
PATIENTS AND METHODS: The study population was recruited from Chengdu, Sichuan Province, China. The study group recruited volunteers in Chengdu from 2007 to 2012, conducted a baseline survey, and subsequently conducted long-term follow-up until December 31, 2019. A total of 22,525 study subjects were enrolled, excluding those who reported a previous history of liver disease, malignancy, and HCC within three months of enrollment. Cox proportional risk regression models were used to screen and determine the various risk factors and their hazard ratios (HR) for HCC in Chengdu, as well as to determine whether the association between other risk factors and HCC was modified by gender.
RESULTS: The study population had a median follow-up of 5.35 years, and a total of 142 people developed HCC, with an incidence rate of 0.71%. Analysis of the multifactorial Cox proportional risk regression model showed that age (age 10 years for 1 group, HR= 1.98, 95% CI: 1.86-2.11, p<0.001), current smoking (HR= 1.25, 95% CI: 1.07-1.31, p=0.031), weekly consumption of pickled vegetables (HR= 1.70, 95% CI: 1.49-1.81, p=0.003) and consumption of pickled vegetables daily (HR= 1.36, 95% CI: 1.21-1.42, p=0.021) were risk factors for HCC, and women (HR= 0.39, 95% CI: 0.28-0.55, p=0.002) and the use of air conditioning (10 years for 1 group, HR= 0.79, 95% CI: 0.68-0.83, p=0.002) were protective factors against HCC. Further analysis revealed that the association between length of time using air conditioning and HCC was heterogeneous among men and women (p=0.007) and that there was an interaction between sex and use of air conditioning in the association with HCC development (p<0.001).
CONCLUSIONS: The Chengdu population has a high incidence of HCC and numerous risk factors for HCC. There is a synergistic interaction between sex and length of time using air conditioning in their role in the development of HCC.
