目的 :为探讨不同年龄组胃癌的发病特点。方法 :1 985年 1月～ 1 999年 5月间内镜检出胃癌 1 1 0 1例 ,将其分成 6个不同年龄组进行对比分析。结果 :≤ 40岁组胃体癌最多 ,其他年龄组均以胃窦癌最多 ,各年龄组均以 Borrmann 型和低分化腺癌最多。胃癌百分比 ,≤ 6 0岁组前 5年显著高于后 5年 ,而 >6 0岁组则相反 ,41岁～ 6 0岁组朝鲜族显著高于汉族 ,而 >6 0岁组则相反 ,≤ 5 0岁组女性显著高于男性 ,而 >5 0岁组则相反 ,分化较好的癌和 Borrmann 、 型 >70岁组显著高于≤ 40岁。结论 :不同年龄组胃癌在发病年段、性别、民族、部位和肉眼及病理类型上均有不同的发病特点。
Objective: To investigate the incidence of gastric cancer in different age groups. Methods: From January 1985 to May 1999, 1 101 cases of gastric cancer were detected by endoscopy, and divided into 6 different age groups for comparative analysis. Results: Gastric cancer was the most common in patients ≤ 40 years of age with the largest percentage of gastric cancers in other age groups, most of which were Borrmann type and poorly differentiated adenocarcinoma in all age groups. The percentage of gastric cancer was significantly higher in the first five years of age than 60 years old compared with the last five years, while in the group of> 60 years old, the Korean nationality in 41 years old to 60 years old group was significantly higher than Han nationality, while the> 60 years old group was opposite, Women ≤ 50 years old were significantly higher than men, while> 50 years old. On the contrary, well-differentiated cancers and Borrmann, type> 70 years old were significantly higher than ≤ 40 years old. Conclusion: Gastric cancer of different age groups have different incidence characteristics in the age of onset, gender, ethnicity, location, gross and pathological types.
