Impact of fear of recurrence in patients with cancer on caregivers' psychological health: A meta-analysis

Objective: This study aims to quantitatively investigate the relationship between fear of cancer recurrence in patients with cancer and their caregivers' psychological health, examining the extent of the impact of this fear on caregivers. Methods: We conducted a comprehensive search in PubMed, EMBASE, Cochrane Library, Web of Science, CINAHL, and PsycINFO databases from inception until May 2023 for relevant English publications. Pearson correlation coefficients (r) were utilized as effect sizes to assess the overall relationship between fear of recurrence and psychological outcomes among caregivers of patients with cancer.Results: A total of 19 eligible studies were included in the analysis. The findings revealed a moderate positive correlation between fear of recurrence in patients with cancer and caregivers' fear of recurrence and depression. A relatively weaker correlation was observed between patients' fear of recurrence and caregivers' anxiety. Due to considerable heterogeneity (I2 = 91.99%, Q = 212.23), the primary outcome of fear of recurrence in patients with cancer influencing caregivers' fear of recurrence was examined through subgroup analyses.Conclusions: Our meta-analysis established a significant positive correlation between fear of recurrence in patients with cancer and negative psychological consequences among caregivers, including recurrence fear, depression, and anxiety. Future research should explore the evolution of adverse psychological outcomes in both patients with cancer and their caregivers over time and delve into the bivariate psychological impact within the patient-caregiver dyads.
