Epidemiological study on upper gastrointestinal malignant tumor diag-nosed by combination of gastroscopy and pathological analysis during 2020-2021 from Haimen Hospital Affiliated to Nantong University
Objective To investigate epidemiological characteristics of upper gastrointestinal malignant tumor diagnosed by combination of gastroscopy and pathological analysis in Haimen Hospital Affiliated to Nantong University during 2020-2021,to provide reference information for the prevention and treatment of upper gastrointestinal malignant tumor in the local area.Methods All electronic gastroscopy cases of Digestive Endoscopy Center of Haimen Hospital Affiliated to Nantong University from January 2020 to December 2021 were collected,and combined with the data of malignant tumors confirmed by biopsy and pathology,the data of gender,age,gastroscopy diagnosis and pathological results were analyzed,and the previously diagnosed upper digestive tract malignant tumors and multiple examination cases of one person were excluded.Data analysis was performed using Graphpad Prism 5.Results There were 1.64％(291/17 712)of the patients were diag-nosed with upper digestive tract malignant tumors,including 73.54％(214/291)in males and 26.46％(77/291)in females.The highest proportion of patients aged 65-＜75 years was 40.89％(119/291),and 35 patients aged＜55 years were gastric cancer.There were 71 cases of esophageal cancer,202 cases of gastric cancer,3 cases of concurrent gastric cancer combined with esophageal cancer,11 cases of gastric lymphoma,3 cases of duodenal bulbar cancer,and 1 case of descending duode-nal cancer.There were 37 cases with early esophageal and gastric cancer,and the diagnosis rate was 12.71％(37/291).Esophageal cancer was most commonly found in the middle part of the esophagus(59.16％[42/71]),followed by the lower part of the esophagus(35.21％[25/71]),and the upper part of the esophagus had the lowest incidence(5.63％[4/71]),and the pathological type was mainly squamous cell carcinoma(90.14％[64/71]).The pathological types of gastric cancer were adenocarcinoma,and the most common sites were antrum 45.05％(91/202),body of stomach 21.29％(43/202),angle of stomach 19.8％(40/202)and cardia 13.86％(28/202).The mean detection age of esophageal cancer and gastric cancer was(71.43±7.14)and(66.85±11.06)years,respectively.The overall detection age of gastric cancer was lower than that of esophageal cancer,and the difference was statistically significant(t=2.566,P=0.013).The mean age of esophageal cancer detection in males and females was(71.05±7.37)and(74.21±7.89)years,respectively.The age of esophageal cancer de-tection in males was lower than that in females,and the difference was statistically significant(t=2.557,P=0.031).The mean age of detection of gastric cancer in men and women was(66.43±10.58)and(66.84±12.53)years,respectively.There was no significant difference in age between the two groups(t=1.145,P=0.257).Conclusion According to the epidemiological survey from Haimen Hospital Affiliated to Nantong University,the upper gastrointestinal malignant tumor are mainly nesophageal cancer and gastric cancer.The incidence rate in men is higher than that in women and 65-＜75 years old is the highest incidence of upper gastrointestinal malignant tumor.The age of incidence of gastric cancer is lower than esophageal cancer.The age of incidence of esophageal cancer in males is lower than females,and there is no significant difference in the age incidence of gastric cancer between males and females.The younger incidence of gastric cancer and the lower diagnostic rate of early cancer should be emphasized.
