    Abstract:
    We have critically reviewed the scientific literature examining the effect of psychosocial interventions on survival and well-being among adult cancer patients. Only studies using randomization and including a control-group not receiving psychosocial intervention were reviewed. Six studies examined the effect on prognosis. In four of these studies survival increased significantly in the intervention group as compared to the control group. All of these studies, however, have methodological flaws, leaving a possible prognostic effect to be clarified in larger, well-controlled future studies. The effect of psychosocial intervention on various psychosocial variables (such as anxiety and depression) was evaluated in 20 studies. Differences in patient populations, intervention strategies, and outcomes decrease the comparability of the results, and the majority of these studies suffer from methodological flaws as well. A positive effect on anxiety and depression immediately following the intervention is, however, reported in the majority of these studies. It is thus possible that the level of anxiety and depression may be decreased by integrating psychosocial intervention in the overall treatment of cancer.
