中文摘要:目的:分析影响应用表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)治疗非小细胞肺癌骨转移患者预后的相关临床因素。方法:回顾分析复旦大学附属中山医院和同济大学附属上海市肺科医院2009年1月—2010年12月应用EGFR-TKI治疗的132例非小细胞肺癌骨转移患者临床资料,用卡普兰-迈耶统计法估计患者1、2 年生存率,单因素分析( Log-rank 检验) 筛选影响患者预后的风险因素, 用Cox 多因素分析模型进一步确认独立风险因素。结果:132例患者中位生存期15.9个月,1年、2年生存率分别为63.9%、41.5%。单因素分析显示:女性、不吸烟者、血白蛋白值正常者中位生存期显著延长(P<0.05)。多因素分析显示:血白蛋白值是影响患者生存的独立预后因素。结论:对于女性、不吸烟的非小细胞肺癌骨转移患者,应用EGFR-TKI治疗有延长中位生存期的趋势,血白蛋白值低是影响预后的不利因素。
英文摘要:Objective: To analyze the prognostic factors of non-small cell lung carcinoma patients with bone metastases treated with epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI). Methods: The clinical data of 132 non-small cell lung carcinoma patients with bone metastases treated with EGFR-TKI, admitted in Zhongshan Hospital of Fudan University and Shanghai Pulmonary Hospital of Tongji University during January 2009 to December 2010, were retrospectively researched. Kaplan-Meier analysis was used to estimate the 1-year and 2-year survival rates of patients. Log-rank test was used to screen the survival influencing factors and Cox regression was further used to confirm the independent factors. Results: The median survival of the 132 patients was 15.9 months. The 1-year and 2-year survival rates were 63.9% and 41.5%, respectively. Univariate analysis showed that female, nonsmoker, normal serum albumin lever were associated with the good prognosis of patients (P<0.05), while multivariate analysis only revealed that serum albumin level was the independent factor of prognosis. Conclusions: The treatment with EGFR-TKI tends to prolong the median survival time of non-small cell lung carcinoma patients with bone metastases who are female and nonsmokers. Low serum albumin level is an unfavorable prognostic factor.
