Efficacy and safety of low-dose olaparib combined with bevacizumab in elderly patients with recurrent platinum-sensitive ovarian cancer
摘要
Abstract
Objective To investigate the efficacy and safety of low-dose olaparib combined with bevacizumab in elderly patients with recurrent platinum-sensitive ovarian cancer.Methods A total of 102 elderly patients with recurrent platinum-sensitive ovarian cancer admitted to our hospital from January 2021 to January 2023 were selected and divided into 3 groups using the random number table method,with 34 cases in each of the control group,low-dose group and high-dose group.All patients in the three groups received bevacizumab maintenance therapy.On this basis,patients in the low-dose group received oral olaparib at 150 mg twice daily,whereas those in the high-dose group received oral olaparib at 300 mg twice daily.Treatment was administered in 4-week cycles for a total of six maintenance cycles.Clinical efficacy was compared between the two groups,along with changes in tumor marker levels and immune function indices(CD3+,CD4+,and CD8+)before and after treatment.Quality of life was evaluated using the QLQ-C30 questionnaire before and after treatment,and adverse events were recorded.Results The objective response rate(ORR)in both the low-dose and high-dose groups was higher than that in the control group(P＜0.05).After treatment,serum levels of HE4,CA125,and CA199 in the high-dose group were lower than those in the low-dose and control groups(P＜0.05).In all groups,HE4,CA125,and CA199 levels decreased significantly compared with baseline(P＜0.05).Moreover,the reductions in HE4,CA125,and CA199 levels were greater in the high-dose group than in the low-dose and control groups(P＜0.05).Post-treatment CD3+and CD4+levels in the low-dose group were higher than those in the high-dose and control groups(P＜0.05),whereas CD8+levels were lower(P＜0.05).After treatment,CD3+and CD4+levels decreased and CD8+levels increased in all groups compared with baseline(P＜0.05).The magnitude of change in CD3+,CD4+,and CD8+levels was smaller in the low-dose group than in the high-dose and control groups(P＜0.05).Following treatment,scores for physical functioning,global health status,activity,and daily living behavior in the low-dose group were higher than those in the high-dose and control groups(P＜0.05).All groups showed significant improvements in these scores compared with baseline(P＜0.05).Furthermore,the increases in these scores were greater in the low-dose group than in the high-dose and control groups(P＜0.05).Conclusion Low-dose olaparib combined with bevacizumab exhibits comparable efficacy to the high-dose regimen in elderly patients with recurrent platinum-sensitive ovarian cancer,and is superior in improving immune function and quality of life while maintaining a favorable safety profile.关键词
