91例无症状肺癌的临床特点分析

Clinical features of asymptomatic pulmonary carcinoma:An analysis of 91 patients

目的分析无症状肺癌患者的临床特点,评价体检对肺癌早期诊断的临床意义,探讨早期诊断肺癌的策略。方法对近6年在本院发现的91例无症状肺癌患者的临床资料进行回顾性分析。结果无症状肺癌中男性好发,男女比例2∶1,平均年龄(56.63±0.67)岁,在老年与非老年中的分布相近;腺癌最多见,以周围型为主,好发于右肺上叶;主要确诊方法首先是手术,其次是支气管镜检查;非小细胞肺癌早期48例(60.0%)多于晚期的32例(40.0%);12例发生2个部位以上的转移。结论无症状肺癌起病隐匿,被发现时并非完全是早期,应提倡定期体检和早期及时手术。

Objective To analyze the clinical features of patients with asymptomatic pulmonary carcinoma,evaluate the clinical significance of health check-up in early discovery of pulmonary carcinoma and investigate the way to discover the pulmonary carcinoma in its early stages.Methods The clinical data of 91 cases with asymptomatic pulmonary carcinoma in recent 6 years were retrospectively analyzed.Results The majority was men in asymptomatic lung cancer,and male/female ratio was 2：1.Average age was（56.63±0.67） years.The distribution in the elderly and non-elderly was similar. Adenocarcinoma with peripheral type of lung cancer was most common.Furthermore,the diseased were mainly located in superior lobe of right lung.The major diagnosis method was surgery while the secondary method was bronchoscopy.There were 48（60.0%） non-small cell lung cancer patients in early stages and 32（40.0%） in advanced stages.There was a significant difference between two groups.Twelve cases had more than two metastatic sites.Conclusion The outbreak of asymptomatic pulmonary carcinoma is insidious of its onset.It will not be in its early stage once it is confirmed.Accordingly,regular health check-up and timely surgical treatment should be recommended.
