To determine whether a single dose of double immune checkpoint blockade (induction chemoimmunotherapy (ICIT)) adds benefit to induction single-cycle platinum doublet (induction chemotherapy (IC)) in locally advanced head and neck squamous cell carcinoma (HNSCC), patients treated with cisplatin 30 mg/m d1-3 and docetaxel 75 mg/m d1 combined with durvalumab 1500 mg fixed dose d5 and tremelimumab 75 mg fixed dose d5 (ICIT) within the CheckRad-CD8 trial were compared with a retrospective cohort receiving the same chemotherapy (IC) without immunotherapy. The endpoint of this analysis was the complete response rate (CR). A total of 53 patients were treated with ICIT and 104 patients with IC only. CR rates were 60.3% for ICIT and 40.3% for IC ( = 0.018). In the total population ( = 157), the most important predictor to achieve a CR was treatment type (OR: 2.21 for ICIT vs. IC; = 0.038, multivariate analysis). The most diverse effects in CR rates between ICIT and IC were observed in younger (age ≤ 60) patients with HPV-positive OPSCCs (82% vs. 33%, = 0.176), while there was no difference in older patients without HPV-positive OPSCCs (53% vs. 48%). The analysis provides initial evidence that ICIT could result in higher CR rates than IC. Young patients with HPV-positive OPSCCs may have the greatest benefit from additional immune checkpoint inhibitors.
为了确定单剂量双重免疫检查点阻断(诱导化疗免疫疗法(ICIT))是否能为局部晚期头颈部鳞状细胞癌(HNSCC)的诱导单周期铂类双联化疗(诱导化疗(IC))带来更多益处,在CheckRad-CD8试验中,将接受顺铂30mg/m² d1-3和多西他赛75mg/m² d1联合度伐利尤单抗1500mg固定剂量d5以及曲美木单抗75mg固定剂量d5(ICIT)治疗的患者与接受相同化疗(IC)但未进行免疫治疗的回顾性队列进行了比较。该分析的终点是完全缓解率(CR)。共有53例患者接受了ICIT治疗,104例患者仅接受了IC治疗。ICIT组的CR率为60.3%,IC组为40.3%(P = 0.018)。在总人群(n = 157)中,实现CR的最重要预测因素是治疗类型(ICIT与IC相比的OR:2.21;P = 0.038,多变量分析)。在年轻(年龄≤60岁)的HPV阳性口咽鳞状细胞癌(OPSCC)患者中,观察到ICIT和IC之间CR率的差异最大(82%对33%,P = 0.176),而在无HPV阳性OPSCC的老年患者中没有差异(53%对48%)。该分析提供了初步证据,表明ICIT可能比IC导致更高的CR率。年轻的HPV阳性OPSCC患者可能从额外的免疫检查点抑制剂中获益最大。
