title: [The prospective research of risk factors of primary liver cancer in Nanhui County, Shanghai].
abstract: Based on a prospective study including a population size of eighty thousand in Nanhui County, the risk factors of primary liver cancer in Nanhui County were found as follows: history of hepatitis (OR 1.03, 95%CL 1.02-1.04), the length of drinking pond & ditch water (OR 1.16, 95% CL 1.02-1.32) and the length of drinking river water (OR 1.25, 95% CL 1.09-1.43). The length of drinking shallow well water (OR 0.65, 95% CL 0.59-0.73) and deep well water (including tap water, OR 0.20, 95% CL 0.16-0.25) seemed to be the protective factors of PLC. These data are useful for PLC prevention and to identify the high-risk individuals in Nanhui County.
