This population-based retrospective study compares the efficacy of cisplatin (cis-RT) vs cetuximab (cetux-RT) with concurrent radiation as definitive treatment in patients with oropharyngeal carcinoma (OPC).
Patients with OPC treated in Alberta with cis-RT or cetux-RT between 2006 and 2016 were evaluated. Median disease-free survival (DFS) and overall survival (OS) were assessed using the Kaplan-Meier method. Multivariable analysis (MVA) was completed with a Cox proportional hazards model.
Among 546 patients with OPC, 431 (78.9%) received cis-RT and 115 (21.1%) cetux-RT. Patients treated with cetux-RT were more likely to develop a recurrence after treatment compared to cis-RT (25% vs 15%, P = .01). On MVA, current smoking, human papillomavirus (HPV)-negative status, higher Charlson comorbidity index (CCI), T-stage, and cetux-RT predicted for worse DFS and OS. Outcomes in older patients with a higher CCI still favored cis-RT.
Our data reaffirm results from randomized studies showing better survival outcomes with cis-RT compared to cetux-RT even among those who are >65 with CCI ≥3.
这项基于人群的回顾性研究比较了顺铂(顺铂同步放疗)与西妥昔单抗(西妥昔单抗同步放疗)联合同步放疗作为口咽癌(OPC)患者确定性治疗的疗效。
对2006年至2016年间在艾伯塔省接受顺铂同步放疗或西妥昔单抗同步放疗的OPC患者进行评估。采用Kaplan-Meier方法评估无病生存期(DFS)和总生存期(OS)的中位数。使用Cox比例风险模型完成多变量分析(MVA)。
在546例OPC患者中,431例(78.9%)接受顺铂同步放疗,115例(21.1%)接受西妥昔单抗同步放疗。与顺铂同步放疗相比,接受西妥昔单抗同步放疗的患者治疗后更易复发(25%对15%,P = 0.01)。在多变量分析中,当前吸烟、人乳头瘤病毒(HPV)阴性状态、较高的Charlson合并症指数(CCI)、T分期和西妥昔单抗同步放疗预示着DFS和OS较差。CCI较高的老年患者的结局仍有利于顺铂同步放疗。
我们的数据再次证实了随机研究的结果,表明即使在CCI≥3的65岁以上患者中,顺铂同步放疗的生存结局也优于西妥昔单抗同步放疗。
