在 6 个数据库（Scopus、Cochrane Central Register of Controlled Trials (CENTRAL)、PsyArticles、CINAHL、PubMed 和 Web of Science）中检索了 2000 年 1 月至 2020 年 4 月期间发表的相关文章。
纳入癌症个体反刍的干预相关实验研究（包括实验组和对照组）的结果。使用综合Meta分析进行数据分析。计算Hedges’ g 和 95% 置信区间 (CI) 以估计效果。此外，还创建了漏斗图并使用I 2检验分析了异质性。研究还使用了PRISMA。
纳入8项研究，包括 856 名癌症患者。一半的研究 ( n = 4) 是随机对照试验，其中六项进行了基于正念的干预。干预措施对癌症患者的反刍有显著影响（z = -2.356，Q = 167.663，p < 0.001，I 2 = 95.825%）。效应大小为 -0.894（95% CI = [-1.638, -0.150]）且具有统计学意义（p < 0.001）。
This study aimed to examine the effects of interventions on rumination among individuals with cancer.
A systematic review and meta-analysis.
Six databases (Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), PsyArticles, CINAHL, PubMed and Web of Science) were searched for relevant articles published between January 2000 and April 2020.
The findings of experimental studies (including both experimental and control groups) related to interventions to effect rumination of individuals with cancer were included. Comprehensive meta-analysis was used to analyse the data. Hedges’ g and 95% confidence intervals (CIs) were computed to estimate the effect. Additionally, funnel plots were created and heterogeneity was analysed using the I2 test. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was used.
Eight studies, which included a total sample of 856 individuals with cancer, were included. Half of the studies (n = 4) were randomised controlled trials, and six of them had conducted mindfulness-based interventions. The interventions had significant effects on rumination among individuals with cancer (z = −2.356, Q = 167.663, p < 0.001, I2 = 95.825%). The effect size was −0.894 (95% CI = [−1.638, −0.150]) and statistically significant (p < 0.001).
The interventions had reduced rumination among individuals with cancer. These effects should be interpreted with caution because there was a high level of heterogeneity. However, only a few studies were included, and the findings underscore the need for further research.
Many individuals are likely to benefit from rumination-focused interventions, especially mindfulness-based interventions. Nurses should utilise available opportunities to facilitate the optimal management of cancer-related rumination.
