Cancer patients who use alternative medicine die sooner
Many cancer patients use some form of complementary and alternative medicine (CAM), mostly as an adjunct to conventional cancer therapies to improve the symptoms of the disease or to alleviate the side-effects of the often harsh cancer-therapy. The hope is that this approach leads to less suffering and perhaps even longer survival - but is this really so? In a recently published study, Korean researchers evaluated whether CAM-use influenced the survival and health-related quality of life (HRQOL) of terminal cancer patients. From July 2005 to October 2006, they prospectively studied a cohort study of 481 cancer patients. During a follow-up of 163.8 person-years, they identified 466 deceased patients. Their multivariate analyses of these data showed that, compared with non-users, CAM-users did not have better survival. Using mind-body interventions or prayer was even associated with significantly worse survival. CAM users reported significantly worse cognitive functioning and more
