Clinical Characteristics and Prognostic Analysis of 107 Patients with Bronchioloalveolar Carcinoma

OBJECTIVE To study the clinical characteristics and prognostic factors for bronchioloalveolar carcinoma. METHODS Clinical data from 107 inpatient cases at The Cancer Hospital of Tianjin Medical University, from 1990-2000, were retrospectively reviewed. RESULTS The overall 1, 3 and 5-year survival rates were 88.7, 64.8 and 48.6% respectively. The main prognostic factors were tumor diameter (P= 0.022), bronchial stump (P=0.016), TNM stage (P=0.000), T stage (P= 0.002), N stage (P=0.000) and postoperation radiotherapy (P=0.001). Cox regression analysis suggested that the TNM stage (P=0.000) and tumor diameter (P=0.015) are independent factors affecting the prognosis. CONCLUSION The overall survival rate of BAC patients was superior to those with other non-small cell lung cancer (NSCLC). The TNM stage and tumor diameter were independent factors affecting the prognosis for BAC.

107例细支气管肺泡癌临床特征及预后分析

目的:分析探讨细支气管肺泡癌(BAC)的临床特点及预后因素。方法:对1990年1月～2000年12月于我院接受手术的107例细支气管肺泡癌的临床资料进行分析。结果:细支气管肺泡癌总体1年、3年及5年生存率分别为88.7%、64.8%和48.6%。单因素分析影响预后的因素为肿瘤直径(P=0.027)、支气管断端是否阳性(P=0.016)、TNM分期(P=0.000)、T分期(P=0.002)、N分期(P=0.000)、术后是否放疗(P=0.001);Cox回归多因素分析提示,TNM分期(P=0.000)和肿瘤直径(P=0.015)是独立的预后影响因素。结论:细支气管肺泡癌总体生存率优于其它非小细胞肺癌,影响其预后的因素主要为TNM分期和肿瘤直径。
