Input: Ten RCTs with 1378 women were identified. Of the seven RCTs on group psychological interventions, three were on cognitive behavioural therapy and four were on supportive-expressive group therapy. The remaining three studies were individual based and the types of psychological interventions were not common to either cognitive behavioural or supportive-expressive therapy. A clear pattern of psychological outcomes could not be discerned as a wide variety of outcome measures and durations of follow-up were used in the included studies. The overall effect of the psychological interventions across six studies, on one-year survival, favoured the psychological intervention group with an odds ratio (OR) of 1.46 (95% confidence interval (CI) 1.07 to 1.99). Pooled data from four studies did not show any survival benefit at five-years follow-up (OR 1.03, 95% CI 0.42 to 2.52). There was evidence of a short-term benefit for some psychological outcomes and improvement in pain scores. Psychological interventions appear to be effective in improving survival at 12 months but not at longer-term follow-up, and they are effective in reducing psychological symptoms only in some of the outcomes assessed in women with metastatic breast cancer. However, findings of the review should be interpreted with caution as there is a relative lack of data in this field, and the included trials had reporting or methodological weaknesses and were heterogeneous in terms of interventions and outcome measures.
Output:

This review examined the studies to date to see what effect psychological treatments had on women with metastatic breast cancer. We found 10 studies with a total of 1378 women with metastatic breast cancer. Three of the studies used a psychological treatment known as cognitive behavioural therapy (CBT), four studies used supportive-expressive group therapy (SEGT), while the remaining three studies used treatments that were delivered on an individual basis and were neither CBT nor SEGT. We performed statistical analysis and found that the odds ratio (a measure of association between an intervention and an outcome) for survival of women with metastatic breast cancer one year after receiving psychological treatment was 1.46, suggesting that there was an association between the psychological treatment and improved survival. This finding was not found when looking at the odds ratio of survival at five years. We also found some evidence that psychological treatments in the short term (for example, one year) may produce a small reduction in pain and improve some psychological symptoms. However, making comparisons across these studies was difficult as they differed in their conduct, treatments and measures used. Moreover, we cannot rule out that the psychological treatments could also cause psychological harm.
