支气管肺癌胸片、CT结合纤支镜诊断对照分析

The comparative analysis of the diagnostic results obtained from chest X-ray film,CT and fibre bronchoscope for bronchopul-monary carcinoma

目的对比分析X线胸片、CT和纤维支气管镜(纤支镜)检查对支气管肺癌的诊断准确率,并评价该三种方法结合应用的意义。方法164例支气管肺癌患者包括术前活检和术后病理证实的162例和术前脑、肾CT扫描证实的2例,于1个月内均依次接受了X线胸片、CT以及纤支镜检查。结果164例患者中被发现有170个癌性病灶,126例为中心型癌灶,44例为周围型癌灶。X线胸片、CT和纤支镜对周围型肺癌的诊断准确率分别为31.82%、52.27%和63.64%,对中心型肺癌的诊断准确率分别为32.54%、60.32%和95.24%。三项检查结合对周围型肺癌的确诊率为81.82%,而纤支镜与CT并用对中心型肺癌的确诊率为98.41%。结论在支气管肺癌诊断中,纤支镜明显优于X线胸片与CT,而三项技术并用则可显著提高其确诊率。

Objective To compare the diagnostic accuracy o f chest X -ray film,CT and fibre bronchoscope(FBS)for bronchopul-monary carcinoma (BPC)and to assess the significance of com bined use of above three methods in th e diagnosis.Methods 164patients with BPC in which 162proved by preoperati ve biopsy and postopecative patholo gy and 2proved by preoperative CT sca n of brain and kidney under-went orderly the examinations of chest X -ray film,CT and FBS within one mo nth.Results170cancerous lesions of 164patient s were 44peripheral type and 126central type,respectively.The diagnostic accu racy of chest X -ray film,CT and FBS wa s respectively 31.82%,52.27%,63.64%for peripheral type a nd 32.54%,60.32%,95.24%for centra l type.The diagnostic accuracy of co mbined use by above three methods was 81.82%for peripheral type while that by CT and FBS was 98.41%for central type.Conclusion FBS is obviously superior to chest X -ray film and CT in the diagnosis of BPC,whereas the int egration of three methods can improv e significantly the diagnos-tic accuracy.[
