摘要:

目的 分析全程特瑞普利单抗联合诱导化疗及同步放化疗(CCRT)治疗局部晚期鼻咽癌的临床疗效与安全性。方法 选取2021年1月至2023年12月广西科技大学第二附属医院和广西壮族自治区来宾市人民医院收治的96例初治局部晚期鼻咽癌患者为研究对象。根据是否采用免疫治疗,分为免疫治疗组(n=47)和对照组(n=49),对照组采用GP方案(吉西他滨+顺铂)诱导化疗及CCRT,免疫治疗组在对照组基础上全程联合特瑞普利单抗免疫治疗。比较两组患者的疗效。采用Kaplan-Meier生存曲线评估患者生存情况,log-rank检验比较患者2年无失败生存(FFS)率、2年总生存(OS)率、2年无远处转移生存(DMFS)率、2年局部无复发生存(LRFS)率。采用Cox比例风险回归模型进行患者FFS的影响因素分析。比较两组患者不良反应发生情况。结果 截至随访截止日期,所有患者中13例死亡,其中免疫治疗组6例(12.77%),包括1例免疫性肺炎合并感染死亡、5例鼻咽癌进展或转移导致的死亡;对照组7例(14.28%),均为鼻咽癌进展或转移导致的死亡。治疗结束后3个月,免疫治疗组完全缓解(CR)36例,部分缓解(PR)10例,病情稳定(SD)1例;对照组CR 37例,PR 10例,SD 2例。免疫治疗组客观缓解率为97.87%(46/47),对照组为95.92%(47/49);两组疾病控制率分别为100%(47/47)、100%(49/49),差异均无统计学意义(χ2=0.30,P=0.582;P>0.999)。免疫治疗组、对照组2年FFS率分别为85.10%、67.34%,差异有统计学意义(χ2=4.23,P=0.040);2年OS率分别为97.87%、93.87%,差异无统计学意义(χ2=1.10,P=0.294);2年DMFS率分别为89.36%、79.59%,差异无统计学意义(χ2=2.00,P=0.158);2年LRFS率分别为95.74%、87.75%,差异无统计学意义(χ2=2.41,P=0.121)。多因素分析显示,联合免疫治疗、年龄、性别、病理类型、T分期、N分期、美国癌症联合委员会分期、放疗时长、EBV-DNA数值、EBV抗体均不是患者FFS的独立影响因素(均P>0.05)。两组患者白细胞减少、中性粒细胞减少、血小板减少、贫血、肺炎、甲状腺功能减退、发热、乏力、体重下降、胃肠系统反应发生率差异均无统计学意义(均P>0.05)。结论 全程应用特瑞普利单抗联合诱导化疗及CCRT,虽未显著改善局部晚期鼻咽癌患者近期疗效及2年OS率、DMFS率、LRFS率,但可提高2年FFS率,且不增加不良反应。

Abstract:

Objective To analyze the clinical efficacy and safety of full-course toripalimab combined with induction chemotherapy and concurrent chemoradiotherapy (CCRT) in the treatment of locally advanced nasopharyngeal carcinoma (LANPC). Methods A total of 96 patients with initially diagnosed LANPC admitted to the Second Affiliated Hospital of Guangxi University of Science and Technology and People's Hospital of Laibin,Guangxi Zhuang Autonomous Region from January 2021 to December 2023 were enrolled. Patients were divided into the immunotherapy group (n=47) and the control group (n=49) based on whether they received immunotherapy. The control group received induction chemotherapy with the GP regimen (gemcitabine+cisplatin) and CCRT,the immunotherapy group received the same regimen as the control group,along with the addition of toripalimab immunotherapy throughout the treatment process. The therapeutic effects of the two groups of patients were compared. Kaplan-Meier survival curves were plotted to evaluate the survival status of the patients,the 2-year failure-free survival (FFS) rate,2-year overall survival (OS) rate,2-year distant metastasis-free survival (DMFS) rate and 2-year locoregional relapse-free survival (LRFS) rate were compared using the log-rank test. The influencing factors of patients' FFS were analyzed using Cox proportional hazards regression model. Adverse events were compared between the two groups. Results By the follow-up deadline,13 patients died,including 6 (12.77%) in the immunotherapy group (1 due to immune-related pneumonitis with infection,5 due to progression or metastasis of nasopharyngeal carcinoma) and 7 (14.28%) in the control group (all due to progression or metastasis of nasopharyngeal carcinoma). At 3 months after treatment,there were 36 cases of complete response (CR),10 cases of partial response (PR),and 1 case of stable disease (SD) in the immunotherapy group; and 37 cases of CR,10 cases of PR,and 2 cases of SD in the control group. The objective response rate was 97.87% (46/47) in the immunotherapy group and 95.92% (47/49) in the control group,the disease control rates of the two groups were 100% (47/47) and 100% (49/49) respectively,with no statistically significant differences (χ2=0.30,P=0.582; P>0.999). The 2-year FFS rates of the immunotherapy group and the control group were 85.10% and 67.34% respectively,with a statistically significant difference (χ2=4.23,P=0.040). The 2-year OS rates were 97.87% and 93.87% respectively,with no statistically significant difference (χ2=1.10,P=0.294). The 2-year DMFS rates were 89.36% and 79.59% respectively,with no statistically significant difference (χ2=2.00,P=0.158). The 2-year LRFS rates were 95.74% and 87.75% respectively,with no statistically significant difference (χ2=2.41,P=0.121). Multivariate analysis showed that,combined immunotherapy,age,gender,pathological type,T stage,N stage,American Joint Committee on Cancer stage,radiation duration, EBV-DNA level,and EBV antibodies were not independent influencing factors of FFS in patients (all P>0.05). There were no statistically significant differences between the two groups in the incidence of leukopenia,neutropenia,thrombocytopenia,anemia,pneumonia,hypothyroidism,fever,fatigue,weight loss,or gastrointestinal system reactions (all P>0.05). Conclusions The full-course toripalimab combined with induction chemotherapy and CCRT,although does not significantly improve the short-term efficacy,2-year OS rate,DMFS rate,or LRFS rate of patients with LANPC,it can increase the 2-year FFS rate,and not increase adverse reactions.
