摘要：

目的探讨卡瑞利珠单抗联合阿帕替尼及化疗二线或以上治疗人表皮生长因子受体-2（HER-2）阴性晚期胃癌的疗效及安全性。方法选取2018年3月至2021年9月betway必威登陆网址 附属肿瘤医院收治的一线治疗失败的HER-2阴性晚期胃癌患者66例,根据治疗方案不同将患者分为研究组（n=22例）和对照组（n=44例）,研究组采用卡瑞利珠单抗联合阿帕替尼及化疗方案治疗,对照组采用单纯化疗治疗。比较两组患者近期疗效、无进展生存期（PFS）、总生存期（OS）和不良反应发生情况,Cox回归分析患者预后的影响因素。结果治疗至少2~4个周期后,研究组和对照组患者的客观缓解率（ORR）分别为9.1%（2/22）、0（0/44）,差异无统计学意义（P=0.108）;DCR分别为77.3%（17/22）、45.5%（20/44）,差异有统计学意义（χ2=6.03,P=0.014）。研究组患者未达到中位OS,对照组患者中位OS为11.7个月,差异无统计学意义（χ2=1.59,P=0.207）;研究组患者未达到中位PFS,对照组患者中位PFS为3.2个月,差异有统计学意义（χ2=10.13,P=0.001）。多因素Cox回归分析结果显示,治疗方法是HER-2阴性晚期胃癌患者PFS的独立影响因素（HR=0.33,95%CI为0.15~0.75,P=0.008）。在不良反应方面,研究组与对照组患者谷丙转氨酶升高发生率差异有统计学意义[31.8%（7/22）vs. 6.8%（3/44）,χ2=5.32,P=0.021]。两组患者均无不良反应相关的死亡。结论与单纯化疗比较,卡瑞利珠单抗联合阿帕替尼及化疗二线或以上治疗HER-2阴性晚期胃癌,可延长患者PFS,提高DCR,但谷丙转氨酶升高发生率显著增加。

Abstract:

ObjectiveTo explore the clinical efficacy and safety of the camrelizumab combined with apatinib and chemotherapy as second-line or later therapy in human epidermal growth factor receptor-2 （HER-2） negative advanced gastric cancer.MethodsA total of 66 patients with HER-2 negative advanced gastric cancer and first-line treatment failure in Shandong Cancer Hospital Affiliated to Shandong First Medical University from March 2018 to September 2021 were selected. They were divided into study group （n=22） and control group （n=44） according to the different treatment regimens. The patients in the study group were treated with camrelizumab combined with apatinib and chemotherapy, and the patients in the control group were treated with chemotherapy alone. The short-term efficacy, progression-free survival （PFS）, overall survival （OS） and the occurrence of adverse reactions were compared, and Cox regression analysis was used to analyze the influencing factors of prognosis.ResultsAfter at least 2-4 cycles of treatment, the ORR in the study group and the control group were 9.1% （2/22） and 0 （0/44） respectively, with no statistically significant difference （P=0.108）. DCR in the two groups were 77.3% （17/22） and 45.5% （20/44） respectively, with a statistically significant difference （χ2=6.03,P=0.014）. The study group didn’t reach median OS and the median OS in the control group was 11.7 months, with no statistically significant difference （χ2=1.59,P=0.207）. The study group didn’t reach median PFS and the median PFS in the control group was 3.2 months, with a statistically significant difference （χ2=10.13,P=0.001）. Multivariate Cox regression analysis showed that treatment method was an independent influencing factor for PFS in patients with HER-2 negative advanced gastric cancer （HR=0.33, 95%CI： 0.15-0.75,P=0.008）. In terms of adverse reactions, there was a statistically significant difference in the incidence of elevated alanine aminotransferase between the study group and the control group [31.8% （7/22）vs. 6.8% （3/44）,χ2=5.32,P=0.021]. There were no adverse-related deaths in both groups.ConclusionCompared with chemotherapy alone, camrelizumab combined with apatinib and chemotherapy as a second-line or later therapy in HER-2 negative advanced gastric cancer can prolong PFS and improve DCR, but the incidence of elevated alanine aminotransferase increases significantly.
