新疆不同民族青年肺癌99例临床分析

目的探讨新疆青年肺癌的临床病理特点及民族分布情况。方法收集自1989年9月至2001年7月间我院收治的99例青年肺癌临床资料，按性别、民族、误诊情况和组织学类型进行分析。结果①女性所占比例增高，即男：女为1．75：1；②汉族比例较高；③大部分青年肺癌患者有较明显的临床症状(97．0%)；④细胞类型以腺癌和小细胞未分化癌为居多，占71．1%；⑤误诊率为61．6%。结论青年肺癌发病的性别差异较老年患者小；新疆不同民族发病情况不同，汉族发病相对较多；恶性程度高；晚期患者多；误诊率高。

Clinical analysis of 99 young patients with lung cancer in different nationalities in Xinjiang

Objective To study clinicopathological characteristics and national distribution of lung cancer in patients who were younger than 40 years of age in Xinjiang. Methods The records of 99 patients who were younger than 40 years of age with lung cancer who were diagnosed in our hospital from September, 1989 to July, 2001 were reviewed. Analyses as to gender, nationalities, misdiagnosis and pathological types were performed. Results The female had higher prevalence than the male did, the ratio of male to female was 1.75 to 1. The Han race had higher prevalence than other races did. Most of the patients had clinical manifestations (97.0%). Adenocarcinoma and small cell lung cancer were predominant histologic types, which accounted for about 71.1%. The misdiagnostic rate was 61.6%. Conclusion In young patients with lung cancer, the diffe-rence of incidence between different genders is smaller than that in senile patients. The prevalence of lung can-cer in young people varies in different races in Xinjiang and Han race has the highest prevalence. The malignancy of lung cancer in young patients is high, and most cases are in advanced stage. The misdiagnostic rate is high.
