Malignant pleural effusion (MPE) is a major problem associated with advanced non-small cell lung cancer for which an optimum treatment strategy has yet to be determined. Notably, vascular endothelial growth factor (VEGF) signaling has been found to influence MPE, and bevacizumab, a VEGF ligand inhibitor, can effectively control MPE. Ramucirumab, a human monoclonal antibody specific for VEGF receptor-2, has recently been approved for advanced non-small cell lung cancer. However, it remains unclear which of these agents more effectively control MPE.We describe a case of a 68-year-old man with advanced non-small cell lung cancer in whom ramucirumab plus docetaxel-refractory MPE was responsive to bevacizumab plus docetaxel combination therapy. The patient's MPE progressed after two cycles of ramucirumab plus docetaxel second-line chemotherapy. After switching to bevacizumab plus docetaxel, a computed tomography scan revealed a decreased MPE after two cycles of treatment.Bevacizumab may be more effective for treating MPE. However, further investigations are still warranted to determine the optimal VEGF-targeted agent for this condition.
恶性胸腔积液(MPE)是晚期非小细胞肺癌相关的一个主要问题,目前尚未确定最佳治疗策略。值得注意的是,已发现血管内皮生长因子(VEGF)信号传导会影响MPE,而VEGF配体抑制剂贝伐单抗可有效控制MPE。雷莫西尤单抗是一种针对VEGF受体-2的人源单克隆抗体,最近已被批准用于晚期非小细胞肺癌。然而,目前尚不清楚这些药物中哪一种能更有效地控制MPE。我们描述了一例68岁晚期非小细胞肺癌男性患者,其雷莫西尤单抗联合多西他赛治疗难治性MPE对贝伐单抗联合多西他赛联合治疗有反应。该患者在接受两个周期的雷莫西尤单抗联合多西他赛二线化疗后MPE进展。改用贝伐单抗联合多西他赛后,计算机断层扫描显示在两个周期的治疗后MPE减少。贝伐单抗可能对治疗MPE更有效。然而,仍有必要进行进一步研究以确定针对这种情况的最佳VEGF靶向药物。
