目的:为探讨天津市近20 a胃恶性肿瘤的发病趋势及特点, 为临床和病理医生提供有价值的诊断思路. 方法:材料来自天津医科大学总医院及第二医院病理科1981/2000年外科病理检查胃恶性肿瘤资料,以Microsoft excel表格形式存储.列统计图表显示胃恶性肿瘤20 a检出趋势.并分别计算各型恶性肿瘤的构成比和平均确诊年龄, 对不同类型,不同性别的胃恶性肿瘤患者年龄进行方差分析(ANOVA)和t检验(或u检验). 结果:20 a来胃恶性肿瘤无论男、女检出数均呈逐年递增趋势,2000年达到顶峰;检出男3 121例,女1 323例,男女之比为2.36:1.前10 a为1 923例,后10 a为2 542例, 前后10 a之比为0.76:1.其中胃癌所占比例最大96.19%, 确诊年龄也最大(58.3岁).组织学类型中以腺癌最多;男女两性确诊年龄不同,男性(59.8岁)高于女性(54.5岁). 结论:胃恶性肿瘤尤其胃癌的发生与环境危险因素的增多和人口老龄化等有关,所以,做好早期防治工作任重而道远.
Objective: To provide valuable diagnostic ideas for clinicians and pathologists in order to explore the trend and characteristics of gastric malignancies in recent 20 years in Tianjin.Methods: Materials were obtained from Department of Pathology, Tianjin General Hospital and Second Hospital, 1981/2000 Pathological examination of gastric malignant tumor data in the form of Microsoft Excel table column statistical charts show the detection of gastric cancer 20 a trend and were calculated for each type of malignant tumor composition and the average age of diagnosis of different types and genders of the stomach The ANOVA and t test (or u test) were used to analyze the age of patients with malignant tumor.Results: The number of male and female patients with gastric malignancies in 20 years showed an increasing trend year by year and peaked in 2000; There were 1 323 cases of female and female, the ratio of male to female was 2.36: 1. The first 10 a was 1 923 cases, the second 10 a was 2 542 cases, the ratio of anterior to posterior 10 a was 0.76: 1. Among them, the proportion of gastric cancer was 96.19% The diagnosis of adenocarcinoma was the most common among histological types, while the male and the female were 59.5 years old (54.5 years old) .Conclusion: The incidence of gastric cancer, especially gastric cancer and environmental risk factors Increase and aging population Therefore, it is a long way to go before we can make good prevention and control work.
