Efficacy and safety of transarterial infusion of anti-PD-1 in the treatment of advanced or metastatic acral and mucosal melanomas.

This study aimed to evaluate the efficacy and safety of transarterial infusion of programmed cell death receptor-1 (PD-1) antibody therapy in advanced or metastatic acral and mucosal melanomas. Eleven patients with acral or mucosal melanoma were referred to the department of Internal Medicine-Oncology in Huazhong University of Science and Technology Union Shenzhen Hospital from January 2019 to August 2020. These patients received transarterial infusions of PD-1 antibody and intravenous infusions of albumin-bound paclitaxel. The median duration of follow-up was 8 months. The patients were treated with transarterial infusion of PD-1 antibody and intravenous infusion of albumin-bound paclitaxel. in study, We collected and recorded immunotherapy-related adverse events. The results showed that the response rate (RR) and the disease control rate (DCR) of the patients (seven with acral melanoma, four with mucosal melanoma) were 54.5 % and 90.9 %, respectively. No grade 3-4 adverse events or major complications were observed during the study. The median progression-free survival was 10 months. The transarterial infusion of PD-1 antibody has remission and control effects on acral and mucosal melanomas, which is important for the clinical care of these patients.

Retrospectively analysis of characteristics and risk factors of immune treatment-related hepatic adverse events in malignant tumor / 中华肿瘤杂志

Objective@#To explore the clinical features and risk factors of hepatic injury due to immune checkpoint inhibitors (CPI) therapy in malignant tumor.@*Methods@#Data of 112 patients (64 men and 48 women) who received CPI between January 2016 and March 2019 in Chinese Academy of Medical Sciences and Peking Union Medical College Shenzhen Hospital, and Huazhong University of Science and Techology Union Shenzhen Hospital were retrospectively collected. The median age of these patients was 60 years.@*Results@#Hepatic adverse events were observed in 30 patients out of 112 patients (26.8%). Among them, the incidence of grade 3-5 hepatic adverse events were 7.14% (8/112). The median time of hepatic adverse event occurrence was 3 weeks (2-30) after undergoing therapy. The results of univariate and multivariate analyses showed that liver cancer was attributed to the CPI induced hepatitis (P<0.05). Patients with severe hepatic injury got almost complete resolution after receiving methlprednisolone for 4 to 6 weeks.@*Conclusion@#Live cancer is the risk factor of CPI-related hepatic adverse events.
