Background and objective: The prognosis for patients with lung cancer and brain metastases remains poor, with approximately 6 months of survival, despite active measures after treatment. In this study, we determined and analyzed clinical parameters that affect the survival of patients with lung cancer and brain metastases to provide clinical guidance.
Methods: Lung cancer cases with brain metastases were retrospectively collected during 2002 and 2008 from Shanghai Chest Hospital, Shanghai Jiao Tong University. Kaplan-Meier method and Cox regression were performed for univariate and multivariate analyses, respectively, to explore independent predictors influencing the survival of patients with lung cancer and brain metastases.
Results: Age, Eastern Cooperative Oncology Group performance status (ECOG PS), metastasis interval, number of metastasis, treatment method, treatment period, symptoms of brain metastases, extracranial metastasis, and brain metastasis order were factors that affect the survival of patients with brain metastases as confirmed through the Kaplan-Meier method. Treatment periods and extracranial metastasis were independent survival predictors in patients with lung cancer and brain metastasis as indicated by Cox proportional hazard model.
Conclusions: Treatment periods and extracranial metastasis were independent predictors of survival of patients with lung cancer and brain metastasis. Treatment periods and extracranial metastasis were independent predictors of survival of patients with lung cancer and brain metastasis.
背景与目的 脑转移的肺癌患者预后差，采取积极治疗措施后也仅有约6个月的生存时间。本研究对可能影响肺癌脑转移生存的临床因素进行收集和分析，以期为指导临床实践提供一定的研究证据。方法 回顾性收集上海交通大学附属胸科医院2002年-2008年有病理组织确诊并发生脑转移的肺癌病例。采用Kaplan-Meier生存曲线、Cox多因素生存分析模型进行生存分析，得到影响脑转移生存的独立预测因素。结果 年龄、美国东部肿瘤协作组体能状态（Eastern Cooperative Oncology Group Performance Status, ECOG PS）评分、转移间隔时间、转移数目、治疗方法、治疗周期、脑转移症状、颅外转移、脑转移次序能够影响到肺癌脑转移患者的生存。采用Cox多因素回归分析得到治疗周期和颅外转移是肺癌脑转移生存时间的独立预测因素。结论 治疗周期和颅外转移是肺癌脑转移生存时间的独立预测因素。.
