摘要
背景PD-1和PD-L1抑制剂已成为治疗头颈部鳞状细胞癌(HNSCC)患者的有效方法:方法:对PD-1和PD-L1抑制剂在HNSCC中的应用进行系统回顾和荟萃分析。结果:中位总生存期(mOS)、中位无进展生存期(mPFS)、实体瘤反应评价标准(RECIST)和治疗相关不良事件(TRAEs):11项试验报告了1088名患者的数据(平均年龄59.9岁,范围18-90岁)。总生存期为 7.97 个月(范围:6.0-16.5)。所有研究的平均 mPFS 为 2.84 个月(范围:1.9-6.5)。与PD-L1抑制剂相比,PD-1抑制剂的RECIST进展期病变率较低(42.61%,95%置信区间[CI]:36.29-49.06 vs. PD-L1抑制剂):36.29-49.06 vs. 56.79%,95% 置信区间 [CI]:49.18-64.19,P 结论:Meta分析表明了PD-1和PD-L1抑制剂在HNSCC中的疗效,并提示PD-1和PD-L1抑制剂在某些RECIST标准上可能存在差异。未来有必要研究这些发现的临床意义。
Programmed death 1 (PD-1) and ligand (PD-L1) inhibitors in head and neck squamous cell carcinoma: A meta-analysis.
Background: PD-1 and PD-L1 inhibitors have emerged as promising treatments for patients with head and neck squamous cell carcinoma (HNSCC).
Methods: Systematic review and meta-analysis of PD-1 and PD-L1 inhibitors in HNSCC. Outcomes: median overall survival (mOS), median progression-free survival (mPFS), Response Evaluation Criteria in Solid Tumors (RECIST) and treatment-related adverse events (TRAEs).
Results: Eleven trials reported data on 1088 patients (mean age: 59.9 years, range: 18-90). The total mOS was 7.97 months (range: 6.0-16.5). Mean mPFS for all studies was 2.84 months (range: 1.9-6.5). PD-1 inhibitors had a lower rate of RECIST Progressive Disease than PD-L1 inhibitors (42.61%, 95% confidence interval [CI]: 36.29-49.06 vs. 56.79%, 95% CI: 49.18-64.19, P < 0.001). The rate of TRAEs of any grade (62.7%, 95% CI: 59.8-65.6) did not differ.
Conclusions: Meta-analysis shows the efficacy of PD-1 and PD-L1 inhibitors in HNSCC and suggests a possible difference in certain RECIST criterion between PD-1 and PD-L1 inhibitors. Future work to investigate the clinical significance of these findings is warranted.
