对无神经系症状,各种常规检查无转移性病变的非小细胞肺癌患者术前24～48小时的脑部CT进行了前瞻性研究。患者158例,年龄40～80(平均64.1)岁。鳞癌79例,间变型鳞癌28例,腺癌36例,鳞腺癌、支气管肺泡癌和未定型癌各5例。脑部CT检查结果:真阳性5例,经开颅活检术确诊;假阳性1例,活检为胶质瘤。术后随访149例,在12个月内发生神经系症状,脑部CT复查确定为脑转移为假阴性,共5例。真阳性包括腺癌3例,鳞癌和鳞腺癌
For non-small cell lung cancer patients with no neurological symptoms, 24 hours to 48 hours before surgery, a prospective study was performed on non-small cell lung cancer patients with conventional scans. There were 158 patients aged 40-80 (mean 64.1) years old. There were 79 cases of squamous cell carcinoma, 28 cases of metastatic squamous cell carcinoma, 36 cases of adenocarcinoma, and 5 cases of squamous cell carcinoma, bronchoalveolar carcinoma, and 5 unaltered carcinomas. Brain CT examination results: 5 cases were true positive, confirmed by craniotomy; 1 case was false positive, and biopsy was glioma. A total of 149 patients were followed up and neurological symptoms occurred within 12 months. Brain CT scans confirmed that brain metastases were false negatives. There were 5 cases. True positives include 3 adenocarcinomas, squamous cell carcinoma and squamous cell carcinoma
