This summary table contains detailed information about research studies. Summary tables offer an informative look at the science behind many breast cancer guidelines and recommendations. However, they should be viewed with some caution. In order to read and interpret research tables successfully, it is important to understand some key concepts. Learn how to read a research table.
Introduction: Some randomized controlled trials have studied whether support groups improve long-term survival for women with breast cancer.
A 1989 landmark study found women with metastatic breast cancer lived an average of 18 months longer if they joined a support group . However, more recent, larger studies have found no benefit from support groups on breast cancer survival [2-7].
Support may still be important to survival. Some data suggest women with breast cancer who have more social support have better survival (see Table 53).
The differences in results may be due to the types of social support studied.
Cohort studies have mostly studied the social support people get from social networks, such as friends and family. Randomized trials have mostly studied social support from strangers, such as support groups.
Further studies are needed to know whether there is a difference between these two kinds of social support and breast cancer survival.
Study selection criteria: Randomized controlled trials with at least 50 participants and meta-analyses.
