摘要：OBJECTIVES Depression, which is the most common comorbidity in breast cancer (BC) patients, has adverse effects on patients’ quality of life, disease progress, and survival. METHODS The protocol of this study was registered in PROSPERO (registration No. CRD42019121494). We electronically searched published studies through January 2019 with the aim of finding articles that investigated the prevalence of depression among BC survivors. Web of Science, Scopus, PubMed/MEDLINE, Science Direct, and Google Scholar were searched to obtain relevant published studies. This review included 14 cross-sectional and 4 cohort studies published from 2000 to 2018. We used a random-effects model to conduct the meta-analysis and generated a summary estimate for the pooled prevalence with 95% confidence intervals (CIs). A subgroup analysis was also conducted based on the depression assessment tool used and the study design. RESULTS The total sample size of the studies contained 2,799 women with BC, including 1,228 women who were diagnosed with depression. The pooled prevalence of depression among Iranian women with BC was 46.83% (95% CI, 33.77 to 59.88) with significant heterogeneity (I 2 =98.5%; p<0.001). The prevalence of depression ranged from 14.00% (95% CI, 4.91 to 23.09) to 95.90% (95% CI, 91.97 to 99.83). The results of the subgroup analyses suggested that the depression assessment tool, year of publication, and study design were sources of heterogeneity. CONCLUSIONS Our findings indicate a high prevalence of depression among BC patients, underscoring the urgent need for clinicians and health authorities to provide well-defined social and psychological supportive care programs for these patients.
