Objective The incidence rate of esophageal carcinoma in ChangZhi area located in the TaiHang Mountain, is very higher. The character of general demology and environmental factors were observed and analyzed to explore the susceptibility to esophageal carcinoma in cases and controls with different cytochromeP4501AlExon7 MSP1 genotypes. This could contribute to finding the cause of disease and suggesting the level of predicting the esophageal carcinoma susceptibility.
