目的分析肺结核合并肺癌的临床特征与影像学特点,提高肺结核合并肺癌的诊断率。方法回顾性分析118例肺结核合并肺癌患者的临床特征和影像学表现,并与同期单纯肺癌96例、单纯肺结核120例进行对照分析。结果肺结核合并肺癌组胸痛、呼吸困难少于单纯肺癌组,乏力、盗汗多于单纯肺癌组;与单纯肺结核组比较发热少于单纯肺结核组,刺激性咳嗽、持续性胸痛和血性胸水多于单纯肺结核组,有显著性差异(P<0.01)。影像上肺结核合并肺癌组斑片索条影、钙化影多于单纯肺癌组;团块影伴分叶、毛刺、小泡征并肺不张多于单纯肺结核组,小结节影,空洞、空腔影少于单纯肺结核组,有显著性差异(P<0.01)。结论临床医师在关注肺结核患者时,应警惕并发恶性变的可能,并尽早进行多种检查,以提高肺结核合并肺癌的诊断率。
Objective To analyze the clinical characteristics and imaging features of pulmonary tuberculosis complicated with lung cancer and to improve the diagnostic rate of pulmonary tuberculosis complicated with lung cancer. Methods A retrospective analysis of 118 cases of pulmonary tuberculosis with lung cancer in patients with clinical features and imaging findings, and 96 cases of simple lung cancer over the same period, simple tuberculosis 120 cases were compared. Results Compared with simple lung cancer group, pulmonary tuberculosis complicated with lung cancer had less chest pain and dyspnea than simple lung cancer group, fatigue and night sweat were more than simple lung cancer group. Compared with simple pulmonary tuberculosis group, fever was less than simple pulmonary tuberculosis group, irritating cough, persistent chest pain and bloody pleural effusion more than simple tuberculosis Group, there was significant difference (P <0.01). Image on pulmonary tuberculosis with lung cancer group patch cord, calcification more than simple lung cancer group; block shadow with lobe, burr, vesicles levy and atelectasis more than tuberculosis group, small nodules, empty, empty Cavity less than simple pulmonary tuberculosis group, there was a significant difference (P <0.01). Conclusions Clinicians should pay attention to the possibility of malignant transformation when paying attention to patients with pulmonary tuberculosis. And they should conduct various examinations as soon as possible to improve the diagnosis rate of pulmonary tuberculosis complicated with lung cancer.
