摘要 目的探讨影响非小细胞肺癌非单发脑转移患者立体定向放疗效果的因素。方法选取接受立体定向放疗的非小细胞肺癌非单发脑转移患者52例,放疗结束后28~35 d内采用WHO实体瘤疗效评价标准计算客观有效率(ORR)、疾病控制率(DCR);随访2年,统计颅内病灶无进展时间(iPFS)、总生存时间(OS)。以ORR、DCR为短期疗效指标,iPFS、OS为长期疗效指标,分析不同临床特征患者ORR、DCR、iPFS、OS差异,采用多因素Logistic回归模型、Cox等比例风险模型分析影响患者短期疗效和长期疗效的因素。结果是否接受靶向治疗、不同GPA评分、不同转移灶最大径、不同转移灶总体积及瘤周水肿带直径患者ORR、iPFS、OS比较差异有统计学意义(P均<0.05)。多因素分析显示,颅外病灶控制情况、原发灶控制情况、是否靶向治疗、GPA评分、转移灶最大径、转移灶总体积是影响OS、iPFS的主要因素(P均<0.05)。结论是否靶向治疗、GPA评分、转移灶最大径和转移灶总体积与非小细胞肺癌非单发脑转移患者放疗的临床疗效相关。
