以脑转移症状为首发表现的老年肺癌36例临床分析

Clinical analysis of 36 elderly lung cancer patients with first symptoms of brain metastases

目的探讨以脑转移为首发表现的老年肺癌的临床特点。方法分析１９８６～１９９６年收治的以脑转移症状为首发表现的３６例老年肺癌患者。结果腺癌、小细胞肺癌较鳞癌多，外周型肺癌远多于中央型，非手术组中位生存期５个月，手术组中位生存期１４个月，误诊率达７７．８％。结论本形式肺癌误诊率高，预后差，放疗、化疗有一定帮助。

Objective To explore the clinical characteristics of elderly lung cancer patients with first symptoms of brain metastases. Methods The authors analysed the records of 36 elderly lung cancer patients who manifested firstly by brain metastases hospitalized between 1986 and 1996. Results Adenocarcinoma and small cell lung cancers were more common than squamous lung cancer;peripheral lung cancer was much more common than central lung cancer.The median survival time in patients with surgical treatment was 14 months and in patients without surgical treatment was 5 months. Conclusions Lung cancer of this type is easily misdiagnosed with a poor prognosis.Radiation therapy and chemotherapy are of benefit to the disease.Patients with surgical treatment have a better prognosis.
