原发性支气管癌,简称为肺癌,是指一种发于支气管黏膜腺体或上皮组织的恶性肿瘤,临床上发病率较高。据报道,肺原位癌临床治愈率较好,高达95%以上;基于5年生存率,Ⅰ期患者的60%~90%显著高于Ⅲ期及Ⅳ期,因此尽可能在肺癌早期进行诊断及治疗不仅能够有效提高生存率,还能降低医疗成本[1]。肺癌影像学检查结果通常为肺部出现占位性病变,多半可通过进一步检查支气管镜、痰脱落细胞学检查,或经皮肺
Primary bronchial cancer, referred to as lung cancer, refers to a malignant tumor of the bronchial mucosa gland or epithelial tissue, the clinical incidence of higher. According to reports, the clinical cure rate of lung cancer in situ is good, up to 95% or more; based on the 5-year survival rate, 60% to 90% of stage Ⅰ patients were significantly higher than those in stage Ⅲ and Ⅳ, so as far as possible in the early diagnosis of lung cancer And treatment can not only effectively improve the survival rate, but also reduce medical costs [1]. Lung cancer imaging findings usually occur in the lung lesions, mostly through further examination of bronchoscopy, sputum cytology, or percutaneous lung
