目的探讨青年人肺癌的临床及病理学特征。方法对56例40岁以下青年人肺癌及63例中老年人肺癌进行回顾性分析,比较两组临床及病理学特征。结果与中老年组相比,青年组中女性多(P<0.05),平均误诊时间长(P<0.005),误诊率高(P<0.005);小细胞未分化癌23例(41.1%),为主要病理类型(P<0.001)。结论青年人肺癌临床表现复杂多样,误诊率高,病理学特征也明显不同于中老年人肺癌。提高对青年人肺癌的认识,对于减少误诊及早期诊治有临床意义。
Objective To investigate the clinical and pathological features of lung cancer in young people. Methods Fifty-six lung cancer patients younger than 40 years old and 63 middle-aged and elderly patients with lung cancer were retrospectively analyzed. The clinical and pathological features of the two groups were compared. Results There were more women in the youth group (P <0.05), longer average misdiagnosis time (P <0.005), higher misdiagnosis rate (P <0.005), 23 (41.1%) small cell undifferentiated carcinoma, As the main pathological type (P <0.001). Conclusion The clinical manifestations of lung cancer in young people are complex and diverse, the rate of misdiagnosis is high, and the pathological features are also obviously different from those of middle-aged and elderly patients with lung cancer. Raising awareness of lung cancer in young people is clinically significant for reducing misdiagnosis and early diagnosis and treatment.
