PurposeAnti-programmed cell death receptor-1 (PD-1) antibodies have demonstrated antitumor activity in many cancer entities. Hepatic adverse events (AEs) are one of its major side effects, but the overall risks have not been systematically evaluated. Thus, we conducted this meta-analysis to investigate the overall incidence and risk of developing hepatic AEs in cancer patients treated with PD-1 inhibitors.MethodsPubMed, Embase, and oncology conference proceedings were searched for relevant studies. Eligible studies were randomized controlled trials of cancer patients treated with PD-1 inhibitors with adequate data on hepatic AEs.ResultsA total of nine randomized controlled trials with a variety of solid tumors were eligible for the meta-analysis. The use of PD-1 inhibitors significantly increased the risk of developing all-grade hepatic AEs but not for high-grade hepatic AEs in comparison with chemotherapy or everolimus control. Additionally, the risk of all-grade and high-grade hepatic AEs with a nivolumab/ipilimumab combination was substantially higher than ipilimumab. No significant differences in the risk of all-grade and high-grade hepatic AEs were found between PD-1 inhibitors monotherapy and ipilimumab.ConclusionWhile the use of PD-1 inhibitors is associated with an increased risk of developing hepatic AEs in cancer patients, this is primarily for lower grade events.
Objective: To investigate whether patients with epithelial ovarian cancer were affected by delayed chemotherapy during the coronavirus disease pandemic in 2020. Materials and Methods: A delay of more than 21 days in the planned chemotherapy was defined as "delayed chemotherapy." Forty-five patients with epithelial ovarian, fallopian tube, and peritoneal cancer were delayed between January 1 and March 30, 2020 in the First Affiliated Hospital of Chongqing Medical University. Thirty-two cases were enrolled in this study. Neoadjuvant chemotherapy was used in 8 cases; palliative chemotherapy was used in 5 cases; and maintenance chemotherapy was used in 19 cases. Data included age, pathological type, surgical pathological stage, chemotherapy time and CA125 levels were collected. The half-life of CA125 and the decrease in CA125 levels before and after delayed chemotherapy were calculated. Results: No patient got coronavirus disease. Compared with patients of ovarian cancer, fallopian tube epithelial cancer and peritoneal epithelial cancer in the same periods in 2019, the half-life of CA125 in neoadjuvant chemotherapy group and recurrence chemotherapy group were more than 20 days, but there was no significant difference. Only when the delayed chemotherapy took place before CA125 turned negative, accompanied by an interval of more than 60 days, the CA125 half-life and the decreased range of CA125 were totally affected. Conclusion:There was no evidence to support that once chemotherapy was delayed it would influence the decrease of CA125, but whether it would affect the long-term effects such as recurrence and five-year survival rate remains to be further followed up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
