摘要:

目的 探究维迪西妥单抗联合特瑞普利单抗治疗肌层浸润性膀胱癌(MIBC)的临床效果。方法 将87例MIBC患者根据接受新辅助治疗方案的不同,分为对照组(吉西他滨+顺铂联合特瑞普利单抗治疗)47例和研究组(维迪西妥单抗联合特瑞普利单抗治疗)40例,每3周为1个疗程,共治疗3个疗程。计算2组3个疗程后的临床客观缓解率(ORR)和疾病控制率(DCR),以及人表皮生长因子受体2(HER-2)阳性患者的ORR和DCR。免疫组化染色检测2组治疗前后的细胞角蛋白20(CK20)、GATA结合蛋白3(GATA-3)和Ki-67阳性表达情况。酶联免疫吸附试验检测血清血管内皮细胞生长因子(VEGF)和尿液膀胱肿瘤抗原(BTA)水平变化。比较2组治疗过程中3级不良反应发生率。结果 3个疗程后,研究组ORR(75.0% vs. 51.1%)和DCR(95.0% vs. 80.9%)均高于对照组(均P<0.05);研究组HER-2阳性患者ORR高于对照组(81.25% vs. 55.17%,P<0.05),2组DCR差异无统计学意义(100.00% vs. 89.66%,P>0.05)。治疗后,研究组CK20、GATA-3、Ki-67阳性患者比例和尿液BTA、血清VEGF表达水平均低于对照组(均P<0.05)。研究组白细胞减少症3级不良反应发生率低于对照组(0.00% vs. 19.15%,P<0.05),2组中性粒细胞减少症、瘙痒、皮疹等其他3级不良反应发生率差异均无统计学意义(均P>0.05)。结论 维迪西妥单抗联合特瑞普利单抗在MIBC新辅助治疗中具有较高的ORR和DCR,且在HER-2阳性患者中获得了更高的ORR,安全性可控,总体疗效较好。

Abstract:

Objective To explore the clinical effect of disitamab vedotin combined with toripalimab in the neoadjuvant therapy of muscle-invasive bladder cancer (MIBC). Methods A total of 87 MIBC patients were divided into the control group (treated with gemcitabine+cisplatin combined with toripalimab, n=47) and the study group (treated with disitamab vedotin combined with toripalimab, n=40) based on the different neoadjuvant treatment regimens. Every 3 weeks was one course of treatment, for a total of 3 courses of treatment. The clinical objective response rate (ORR) and disease control rate (DCR) after three treatment courses were calculated in two groups, and the ORR and DCR of human epidermal growth factor receptor 2 (HER-2) in positive patients were also caculated. Immunohistochemical staining was used to detect the positive expression levels of cytokeratin 20 (CK20), GATA-binding protein 3 (GATA-3) and Ki-67 before and after treatment in the two groups. Serum vascular endothelial growth factor (VEGF) and urinary bladder tumor antigen (BTA) levels were detected by enzyme-linked immunosorbent assay. The incidence of grade 3 adverse reactions during the treatment process was compared between the two groups. Results After 3 courses of treatment, the ORR (75.0% vs. 51.1%) and DCR (95.0% vs. 80.9%) were higher in the study group than those of the control group (all P<0.05). After three courses of treatment, the ORR of HER-2 positive patients in the study group was higher than that in the control group (81.25% vs. 55.17%, P<0.05). There was no significant difference in DCR between the two groups (100.00% vs. 89.66%,P>0.05). After treatment, the proportions of patients with positive CK20, GATA-3 and Ki-67, urinary BTA, and serum VEGF expression levels were lower in the study group than those in the control group (all P<0.05). The incidence of grade 3 adverse reactions of leukopenia was lower in the research group than that in the control group (0.00% vs. 19.15%, P<0.05). There were no significant differences in the incidence of other grade 3 adverse reactions such as neutropenia, itching and rash between the two groups (all P>0.05). Conclusion Disitamab vedotin combined with toripalimab has high ORR and DCR in the neoadjuvant therapy of MIBC. Moreover, the ORR is higher in HER-2 positive patients, with controllable safety and good overall efficacy.
