肺癌是全球最常见的恶性肿瘤之一,具有很高的发病率和死亡率,在中国一直是威胁人类健康的主要原因。近年来发现青年人的肺癌发病率有较稳定的上升趋势,然而先前关于青年人肺癌临床特点以及预后的统计资料存在很大的差异。由于大量的研究存在对青年人肺癌年龄的不同界定,因此我们很难比较在青年人肺癌研究中所得到的结果。本文就目前青年人肺癌的临床特点及诊治研究结果的差异作一综述。 Lung cancer, one of the most common malignant tumors in the world, has a high morbidity and mortality rate and has been a major cause of threat to human health in China. In recent years, the incidence of lung cancer in young people has been found to have a relatively steady upward trend. However, there are great differences in the previous statistics on the clinical features and prognosis of young people with lung cancer. Because of the large number of studies that define different age groups for lung cancer in young people, it is difficult to compare the results obtained in studies of lung cancer in young people. In this paper, the current clinical features of young people with lung cancer and diagnosis and treatment of the differences between the results are reviewed.
