Abstract:
Objective:To assess the application value of China consensus on the protocol of early gastric cancer screening in Guangdong province.Methods:A new quantitative scoring system was used in Cantonese residents who underwent early gastric cancer screening from March 2018 to March 2019. According to the scores of initial screening, patients were divided into high-risk, medium-risk and low-risk groups. The detection rates of early gastric cancer, precancerous diseases and precancerous lesions under gastroscopy in each group were compared. Chi-square test was performed for statistical analysis.Results:A total of 545 individuals were selected for gastroscopy, in which 32 cases were classified into high-risk group, 184 into medium-risk group and 329 into low-risk group. The results of gastroscopy examination showed that high-risk group had the highest detection rate of early gastric cancer (12.5%), followed by medium-risk group (1.1%) and low-risk group (0) ( χ2=41.85, P<0.01); the detection rates of precancerous diseases exhibited a similar pattern: high-risk group (60.9%) > medium-risk group (52.4%) > low-risk group (34.3%) ( χ2=18.00, P<0.01). The detection rates of precancerous lesions were 17.9%, 8.8% and 8.8%, respectively, with no significant difference ( χ2=2.58, P=0.28). In terms of the positive rate of endoscopy, high-risk group (71.9%) showed the highest positive rate, followed by medium-risk group (57.1%) and low-risk group (40.1%) ( χ2=21.54, P<0.01). Conclusion:China consensus on the protocol of early gastric cancer screeing is of application value for the screening of early gastric cancer and precancerous lesions in the populations at risk of gastric cancer in Guangdong province.
