Abstract

BACKGROUND

Brain metastases are a common complication of advanced non-small cell lung cancer (NSCLC). Patients with brain metastases were excluded from the registration trials of bevacizumab that showed a survival benefit with the use of angiogenesis inhibition.

METHODS

In this study, we pooled data from two separate trials designed to evaluate the risk of central nervous system (CNS) hemorrhage in patients with stable treated brain metastases to look specifically at both the safety and efficacy of bevacizumab and pemetrexed when used as second-line treatment in NSCLC patients with stable treated brain metastases.

RESULTS

We report acceptable safety and promising efficacy from our analysis.

CONCLUSIONS

Our study adds further evidence of safety of administering pemetrexed and bevacizumab to patients with stable brain metastases. There is increasing roles for systemic therapies to treat stable brain metastases for patients with advanced NSCLC.

摘要

背景

脑转移是晚期非小细胞肺癌(NSCLC)的常见并发症。脑转移患者被排除在贝伐单抗的注册试验之外,该试验显示使用血管生成抑制可带来生存获益。

方法

在本研究中,我们汇总了两项独立试验的数据,这些试验旨在评估经治疗病情稳定的脑转移患者发生中枢神经系统(CNS)出血的风险,以专门研究贝伐单抗和培美曲塞在病情稳定的NSCLC脑转移患者中用作二线治疗时的安全性和疗效。

结果

我们的分析显示安全性可接受且疗效有望令人满意。

结论

我们的研究进一步证明了对病情稳定的脑转移患者给予培美曲塞和贝伐单抗的安全性。对于晚期NSCLC患者,全身治疗在治疗病情稳定的脑转移方面发挥着越来越重要的作用。
