RESUMEN
PROBLEM IDENTIFICATION: Anxiety and depression are more prevalent in hematological cancer patients who experience unpredictable illness trajectories and aggressive treatments compared to solid tumor patients. Efficacy of psychosocial interventions targeted at blood cancer patients is relatively unknown. This systematic review examined trials of physical health and psychosocial interventions intending to improve levels of anxiety, depression, and/or quality of life in adults with hematological cancers. LITERATURE SEARCH: PubMed and CINAHL databases were used to perform a systematic review of literature using PRISMA guidelines. DATA EVALUATION/SYNTHESIS: Twenty-nine randomized controlled trials of 3232 participants were included. Thirteen studies were physical therapy, nine psychological, five complementary, one nutritional and one spiritual therapy interventions. Improvements were found in all therapy types except nutritional therapy. CONCLUSIONS: Interventions that included personal contact with clinicians were more likely to be effective in improving mental health than those without. IMPLICATIONS FOR PSYCHOSOCIAL ONCOLOGY: Various psychosocial interventions can be offered but interactive components appear crucial for generating long-standing improvements in quality of life, anxiety and depression.
