摘要: 背景 免疫治疗已成为进展期食管鳞状细胞癌(ESCC)的标准治疗方案,但目前尚缺乏明确的预测免疫相关不良反应(irAEs)的生物标志物,且irAEs与疗效的关系亦不明确。 目的 探讨进展期ESCC患者发生irAEs的预测因素及irAEs与疗效的相关性。 方法 回顾性纳入2020—2023年在南京鼓楼医院接受程序性死亡蛋白1(PD-1)抑制剂治疗的118例进展期ESCC患者为研究对象,通过查阅病历、门诊、再入院、电话等方式对入组患者进行随访,收集患者的临床资料及irAEs情况,根据治疗过程中是否发生irAEs分为irAEs阳性组和irAEs阴性组,采用单因素和多因素Logistic回归分析探讨影响irAEs发生的相关因素。疗效评价为完全缓解(CR)、部分缓解(PR)、疾病稳定(SD)、疾病进展(PD),比较两组的客观缓解率(ORR)、疾病控制率(DCR),采用Kaplan-Meier法绘制生存曲线,采用Log-rank检验比较两组患者无进展生存期(PFS)及总生存期(OS)差异。 结果 118例患者中47例(39.83%)发生irAEs,发生率较高的irAEs为皮肤毒性21例(17.80%)、内分泌毒性16例(13.56%)和肺毒性16例(13.56%)。irAEs阳性组和irAEs阴性组自身抗体谱及抗核抗体(ANA)比较,差异有统计学意义(P<0.05)。单因素Logistic分析显示,自身抗体谱阳性(OR=3.375,95%CI=1.527~7.456,P=0.003)和ANA阳性(OR=3.072,95%CI=1.404~6.722,P=0.005)是irAEs发生的危险因素(P<0.05);多因素Logistic分析结果显示,自身抗体谱阳性(OR=2.367,95%CI=0.841~6.663,P=0.103)和ANA阳性(OR=1.733,95%CI=0.621~4.837,P=0.293)与irAEs的发生无显著关联;但自身抗体谱阳性患者内分泌毒性的发生率高于自身抗体谱阴性患者,ANA阳性患者内分泌毒性和肌毒性的发生率高于ANA阴性患者(P<0.05)。且irAEs阳性组DCR高于irAEs阴性组(χ2=6.690,P=0.010);两组ORR比较,差异无统计学意义(χ2=2.628,P=0.105)。生存分析结果显示,irAEs阳性组中位PFS和中位OS长于irAEs阴性组,差异均有统计学意义(PFS:χ2=9.521,P=0.002;OS:χ2=4.254,P=0.039)。 结论 自身抗体谱或ANA阳性的ESCC患者接受免疫治疗后可能更容易发生irAEs,且irAEs的发生与更好的治疗疗效相关。

Abstract:

Background

Immunotherapy has become the standard regimen for progressive esophageal squamous cell carcinoma (ESCC), but there is a lack of clear biomarkers to predict immune-related adverse events (irAEs), and the relationship between irAEs and efficacy is also unclear.

Objective

To explore the predictive factors associated with the occurrence of irAEs in patients with progressive ESCC and the correlation between irAEs and prognosis.

Methods

A retrospective study was conducted on 118 patients diagnosed with progressive ESCC and treated with programmed death protein 1 (PD-1) inhibitors at Nanjing Drum Tower Hospital from 2020 to 2023. The enrolled patients were followed up through access to medical records, outpatient visits, re-admissions, phone calls. Clinical data and occurrence of irAEs were collected. Patients were divided into the irAEs-positive group and the irAEs-negative group based on the occurrence of irAEs during treatment. Univariate and multivariate Logistic analysis were conducted to analyze the factors influencing the occurrence of irAEs. The efficacy was evaluated as complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD). Objective remission rate (ORR), disease control rate (DCR) were compared between the two groups. Kaplan-Meier survival curve were plotted, and Log-rank test was conducted to compare the progression free survival (PFS) and overall survival (OS) between the two groups.

Results

Among the 118 patients, 47 cases (39.83%) experienced irAEs. The irAEs with higher incidence were dermal toxicity 21 cases (17.80%), endocrine toxicity 16 cases (13.56%) and pulmonary toxicity16 cases (13.56%). The comparison of autoantibody profiles and antinuclear antibody (ANA) between the irAEs-positive group and the irAEs-negative group showed a statistically significant difference (P<0.05). Univariate Logistic analysis showed that autoantibody profile positivity (OR=3.375, 95%CI=1.527-7.456, P=0.003) and ANA positivity (OR=3.072, 95%CI=1.404-6.722, P=0.005) were risk factors for the development of irAEs (P<0.05). Multivariate Logistic analysis showed that autoantibody profile positivity (OR=2.367, 95%CI=0.841-6.663, P=0.103) and ANA positivity (OR=1.733, 95%CI=0.621-4.837, P=0.293) were not significantly associated with the occurrence of irAEs. However, the incidence of endocrine toxicity was higher in autoantibody-positive patients than in autoantibody-negative patients, and the incidence of endocrine toxicity and myotoxicity was higher in ANA-positive patients than in ANA-negative patients (P<0.05). Moreover, the DCR of irAEs-positive group was longer than that of irAEs-negative group (χ2=6.690, P=0.010). Comparing the ORR of the two groups, the difference was not statistically significant (χ2=2.628, P=0.105). Survival analysis results showed that the median PFS and median OS of the irAEs-positive group were longer than those of the irAEs-negative group, all differences were statistically significant (PFS: χ2=9.521, P=0.002; OS: χ2=4.254, P=0.039).

Conclusion

Autoantibody profiles or ANA positivity may be more likely to develop irAEs after immunotherapy in patients with ESCC, and the occurrence of irAEs is associated with better efficacy.
