摘要
背景与目的肺癌是现今全世界发病率和死亡率最高的恶性肿瘤。由于部位特殊和检查方法的局限,周围型肺癌诊断较困难,应用经支气管镜肺活检(TBLB)技术,旨在评价TBLB对周围型肺癌的诊断价值。方法78例周围型肺癌,经支气管镜常规检查无法观察到病变,采用TBLB证实42例。对于未获得诊断的36例周围型肺癌患者,其中22例通过CT引导下经皮肺活检(PNLB)证实,另外14例患者依次经外科手术、淋巴结活检、胸膜活检、胸水细胞学检查等获取标本,经病理学或细胞学检查证实。结果已经病理学或细胞学确诊为肺癌78例,经支气管镜肺活检、刷检的阳性率分别为53.8%、8.9%,联合后总阳性率为57.7%;两种取材方法中,以TBLB的阳性率最高,与刷检相比,差异有统计学意义(P<0.01);随着病灶逐渐增大,活检阳性率逐渐增高;右肺活检阳性率高于左肺,两下叶活检阳性率高于上叶;病例越靠近肺内带和肺门,TBLB的活检阳性率越高;PNLB并发症发生率高于TBLB。结论经支气管镜肺活检检查是确诊周围型肺癌的重要手段之一,联合应用多种取材方法和技术可提高周围型肺癌的诊断准确率。
Background and objective Lung cancer is the leading cause of cancer-related death worldwide. Because the locations of peripheral lung cancer are special, diagnosis of peripheral lung cancer is difficult. The aim of this study was to evaluate diagnostic value of transbronchial lung biopsy （TBLB） in peripheral lung cancer. Methods Transbronehial lung biopsy （TBLB） were performed in 78 cases of peripheral lung cancer which could not be observed by bronchoscope, 42 cases among whom were diagnosed by pathology and cytologic examination. Thirty-six cases of peripheral lung cancer were not able to be diagnosed by TBLB, 22 cases among them were diagnosed by percutaneous lung biopsy （PNLB）, and 14 cases being left were diagnosed by surgical operation, lymphadeuopathy biopsy, pleura biopsy and sputum cytologic examination successively. Results The positive rate produced by transbronchial lung biopsy, brush biopsy were 53.8% and 8.9% respectively. The total positive rate was 57.7%. The positive rate produced by TBLB was higher than that of brush biopsy （P〈0.01）. Along with tumor＇s diameter enlarge, the positive rate of diagnosis was higher. The positive rate of right lung was higher than that of left lung. The positive rate of inferior lung was higher than that of upper lung. The lesions near the inner belt and hilus pulmonis, had the higher positive rate. Complicatin frequency in PNLB was much higher than that in TBLB. Conclusion Transbronchial lung biopsy is an important method in diagnosing of peripheral lung cancer. Combination of TBLB can increase the diagnostic positive rate of peripheral lung cancer.
