The efficacy of interventions to improve psychosocial outcomes following surgical treatment for breast cancer: a systematic review and meta-analysis

This is the first meta-analysis to demonstrate the efficacy of interventions on a range of psychosocial outcomes following breast cancer surgery. The meta-analysis highlighted that cognitive behavioral therapy was consistently the most effective psychosocial intervention promoting improvements in anxiety, depression, and quality of life. However, there are shortcomings in existing studies; the length of the follow-up period is typically short and the generalizability of findings was limited by small samples, both of which should be addressed in future studies.
