Abstract: |
Comments on an article by David Spiegel et al. (see record 2008-13355-009). Based on a very small subsample of 25 estrogen receptor (ER)- negative women with breast cancer, 13 of whom received group therapy, Spiegel et al. conducted an exploratory analysis that found increased survival for these women. They have argued that these women were not protected by hormonal therapies. We tried to replicate their analytic method exactly. Given our inability to replicate their latest exploratory finding, we conclude that it is a chance finding. Women should not be swayed into false hope, but appreciate that strong evidence has emerged that group therapy does not prolong survival. Group therapy does prevent depression and improve quality of life, thus representing a wonderful adjunctive psychosocial treatment for those with cancer.
