793例云南籍肺癌患者特征分析

Characteristics of 793 Cases of Lung Cancer in Yunnan Province

目的了解云南籍肺癌患者的流行病学特征,为云南省肺癌的防治提供参考.方法回顾性分析2009年12月至2011年12月云南省肿瘤医院收治的793例云南籍肺癌患者的病理类型、性别、发病年龄等流行病学特征.结果肺腺癌353例(44.5%)、肺鳞癌241例(30.4%)、小细胞肺癌88例(11.1%)、其他类型111例(14.0%);肺癌患者男女比例为2.7:1,腺癌男女之比为1.45:1,鳞癌高达12.39:1,小细胞肺癌为3.89:1,其他病理类型为2.36:1;肺癌的平均发病年龄为(57.56±0.417)岁,发病高峰集中在41～60岁(50.94%).结论(1)肺腺癌的发病率高,超过了鳞癌;(2)肺癌患者男性居多,男性患者以肺鳞癌为常见病理类型,女性肺癌患者以腺癌多见;(3)肺癌患者发病年轻化,女性患者更加明显.

Objective To understand the epidemiologic features of lung cancer in Yunnan Province,so as to provide reference for the prevention and treatment of lung cancer in Yunnan Province.Method A retrospective study was performed to learn the pathology types,gender and age of 793 lung cancer patients who were admitted in our hospital between 2009 and 2011.Results Adenocarcinoma accounted for 44.5%,followed by squamous cell carcinoma（30.4%）,and small cell carcinoma（11.1%）,other lung cancer patients accounted for 14.0%.The total ratio of male to female was 2.7：1 in lung cancer patients,the ratio was 1.45：1 in cases of adenocarcinoma, 12.39：1 in Squamous cell carcinoma,3.89：1 in small cell carcinoma and 2.36：1 in other pathology types.The average age of lung cancer patients at diagnosis was（57.56±0.417） years,and peak age was between 41 years to 60 years（50.94%）.Conclusions（1） The incidence of adenocarcinoma is higher than squamous cell carcinoma.（2） The percent of male lung cancer patients is higher than that in female,especially in squamous cell carcinoma, while adenocarcinoma more common in female patients.（3） The admitted age is earlier than before,especially in female lung cancer patients.
