OBJECTIVE Endoscopy was used to study the high incidence area of cancer of gastric cardia. METHODS 417 patients with early cardiac cancer and 451 patients with advanced lesions were analyzed to the high incidence point of cardiac cancer. Verifying endoscopic screening of 205 subjects was performed later in the high incidence area of esophageal cancer. (More)
OBJECTIVE To understand the distribution of esophageal squamous cell cancer and precursor lesions in high-risk areas of China, and to provide evidence for determining the reference ranges of detection rates in high-risk areas. METHODS Endoscopy with Lugol's iodine staining was performed on 15 709 local residents aged 40 to 69 years old in Linzhou of Henan(More)
OBJECTIVE To estimate the cost-effectiveness of esophageal cancer endoscopic screening once-in-a-lifetime and to predict the optimal screening age for people in high-risk areas of rural China. METHODS A Markov model was constructed to predict and compare the effect of four esophageal cancer endoscopic screening modalities which varied with different(More)
OBJECTIVE To evaluate the feasibility of DNA image cytometry (DNA-ICM) as a primary screening method for esophageal squamous cell cancer (ESCC). METHODS A total of 5,382 local residents aged 40-69 years from three high-risk areas in China (Linzhou in Henan province, Feicheng in Shandong province and Cixian in Hebei province) from 2008 to 2011 were(More)
In China, esophageal cancer has remained a large burden, and endoscopic screening is expected to reduce esophageal cancer mortality. Therefore, a population-based case-control study was conducted to evaluate the effect of screening. Cases were defined as individuals who had died of esophageal cancer, and controls were residents from the same area (three per(More)
