目的 :探讨延边地区朝鲜族胃癌的流行病学特点。方法 :1985年 1月～ 1999年 5月间内镜检出胃癌 110 1例 ,将其分成朝鲜族和汉族两组进行对比分析。结果 :胃癌检出率 ,两组 80年代均明显高于 90年代 (P <0 .0 1) ,朝鲜族较汉族低且 90年代有显著差异 (P <0 .0 5 )。胃癌百分比 ,胃窦部汉族明显高于朝鲜族 (P <0 .0 5 )。胃体部朝鲜族明显高于汉族 (P <0 .0 1)。两组胃癌均以胃窦癌、BorrmannⅡ型和低分化腺癌最多 ,胃鳞癌均为胃底贲门癌 ,汉族明显多于朝鲜族 (P <0 .0 5 )。结论 :本地区朝鲜族胃癌有自己的流行病学特点 ,这对防治本病有重要意义。
Objective: To investigate the epidemiological characteristics of Korean gastric cancer in Yanbian area. Methods: One hundred and one cases of gastric cancer were detected by endoscopy from January 1985 to May 1999, which were divided into Korean and Han nationality for comparative analysis. Results: The detection rate of gastric cancer in both groups was significantly higher than that in the 1990s in the 1980s (P <0.01). The Korean nationality was lower than the Han nationality in the 1980s and was significantly different in the 1990s (P <0.05). The percentage of gastric cancer was significantly higher in gastric antrum Han than in Korean (P <0.05). The gastric body was significantly higher than the Korean Han (P <0.01). Gastric cancer in both groups were gastric cancer, Borrmann Ⅱ type and poorly differentiated adenocarcinoma, gastric squamous cell carcinoma were gastric cardia cancer, Han significantly more than Koreans (P <0.05). Conclusion: There are epidemiological characteristics of Korean gastric cancer in our region, which is of great significance for the prevention and treatment of this disease.
