This analysis compared the quality-adjusted survival and clinical outcomes of albumin-bound paclitaxel+carboplatin (nab-PC) vs solvent-based paclitaxel+carboplatin (sb-PC) as first-line therapy in advanced non-small-cell lung cancer (NSCLC) in older patients.
Using age-based subgroup data from a randomised Phase-3 clinical trial, nab-PC and sb-PC were compared with respect to overall response rate (ORR), overall survival (OS), progression-free survival (PFS), quality of life (QoL), safety/toxicity, and quality-adjusted time without symptoms or toxicity (Q-TWiST) with ages ⩾60 and ⩾70 years as cut points.
Among patients aged ⩾60 years (N=546), nab-PC (N=265) significantly increased ORR and prolonged OS, despite a non-significant improvement in PFS, vs sb-PC (N=281). Nab-PC improved QoL and was associated with less neuropathy, arthralgia, and myalgia but resulted in more anaemia and thrombocytopenia. Nab-PC yielded significant Q-TWiST benefits (11.1 vs 9.8 months; 95% CI of gain: 0.2-2.6), with a relative Q-TWiST gain of 10.8% (ranging from 6.4% to 15.1% in threshold analysis). In the ⩾70 years age group, nab-PC showed similar, but non-significant, ORR, PFS, and Q-TWiST benefits and significantly improved OS and QoL.
Nab-PC as first-line therapy in older patients with advanced NSCLC increased ORR, OS, and QoL and resulted in quality-adjusted survival gains compared with standard sb-PC.
本分析比较了白蛋白结合型紫杉醇+卡铂(nab-PC)与溶剂型紫杉醇+卡铂(sb-PC)作为老年晚期非小细胞肺癌(NSCLC)一线治疗的质量调整生存和临床结局。
利用一项随机3期临床试验的年龄亚组数据,以年龄≥60岁和≥70岁为切点,比较nab-PC和sb-PC在总缓解率(ORR)、总生存期(OS)、无进展生存期(PFS)、生活质量(QoL)、安全性/毒性以及无症状或无毒性的质量调整时间(Q-TWiST)方面的差异。
在年龄≥60岁的患者中(N=546),与sb-PC(N=281)相比,nab-PC(N=265)显著提高了ORR并延长了OS,尽管PFS改善不显著。Nab-PC改善了QoL,且与较少的神经病变、关节痛和肌痛相关,但导致更多的贫血和血小板减少。Nab-PC产生了显著的Q-TWiST益处(11.1个月对9.8个月;获益的95%CI:0.2-2.6),相对Q-TWiST获益为10.8%(阈值分析中范围为6.4%至15.1%)。在≥70岁年龄组中,nab-PC显示出相似但不显著的ORR、PFS和Q-TWiST益处,并显著改善了OS和QoL。
与标准的sb-PC相比,nab-PC作为老年晚期NSCLC患者的一线治疗可提高ORR、OS和QoL,并带来质量调整生存获益。
