The effect of psychological interventions on fear of cancer recurrence in breast cancer survivors: A systematic review and meta‐analysis

To evaluate the effectiveness of psychological interventions in reducing fear of cancer recurrence in breast cancer survivors.A systematic review and meta-analysis.PubMed, Embase, Cochrane Central Register of Controlled Trials, CINAHL, Scopus, PsycINFO, Web of Science and ClinicalTrials.gov were searched for relevant studies published from 1 January 1976 to 28 November 2020.Eligible randomized controlled trials on psychological interventions for reducing fear of cancer recurrence in breast cancer survivors were included in meta-analysis. Review Manager 5.4 was used to conduct the meta-analysis, and the fear of cancer recurrence score was calculated by using standardized mean differences and 95% confidence intervals. Risk of bias was assessed with the Cochrane risk-of-bias tool. Quality of evidence, sensitivity analyses, and subgroup analyses were also conducted.This systematic review included 16 randomized controlled trials. We found psychological interventions significantly reduced fear of cancer recurrence. Subgroup analyses indicated that mindfulness and acceptance therapy-based interventions reduced fear of cancer recurrence, whereas cognitive-behavioural therapy combined with psychoeducation did not. Interventions with three to eight sessions were effective, while interventions with nine or more sessions were not. Face-to-face interventions were effective, whereas online interventions were not. The quality of evidence for fear of cancer recurrence was evaluated as moderate due to moderate heterogeneity in the included studies.Psychological interventions were effective in reducing fear of cancer recurrence in breast cancer survivors. Mindfulness and acceptance therapy-based interventions and short-term interventions are recommended. Future well-designed randomized controlled trials aiming to examine the effectiveness of psychological interventions in reducing fear of cancer recurrence are needed.The findings of this systematic review may guide the development of psychological interventions and encourage the use of psychological interventions for reducing fear of cancer recurrence in breast cancer survivors.
