通过对术后病理确诊为肺癌的１５３例患者的术前病理分析，术前病理确诊率为５７．５２％，其中痰检阳性率为２２．２２％，纤支镜检阳性率为４９．０２％。中央型显著高于周围型，鳞癌显著高于细支气管肺泡癌。纤支镜检不能替代痰检。主张如临床及Ｘ线诊断肺癌，患者又有手术条件，应积极行开胸探查，争取根治性切除。 According to the preoperative pathological analysis of 153 patients with lung cancer diagnosed by postoperative pathology, the preoperative pathological diagnosis rate was 57.52%. The positive rate of sputum examination was 22.22%, and the positive rate of fibrobronchoscopy was 49.02. %. The central type was significantly higher than the peripheral type, and the squamous cell carcinoma was significantly higher than the bronchioalveolar carcinoma. Fibrobronchoscopy cannot replace sputum examination. Advocates such as clinical and X-ray diagnosis of lung cancer, the patient has surgical conditions, should actively open breast exploration, for radical resection.
