Widespread use of complementary and alternative medicine among non-Hodgkin lymphoma survivors.

There are few studies examining complementary and alternative medicine (CAM) use and beliefs among non-Hodgkin lymphoma (NHL) survivors. Seven hundred and nineteen patients with NHL from the University of Iowa/Mayo Clinic Molecular Epidemiology Resource who completed the 3-year post-diagnosis questionnaire were included in this study. Altogether 636 (89%) reported ever using CAM, with 78% utilizing vitamins, 54% alternative therapies and 45% herbals. Female gender was associated with increased overall CAM use (p=0.0001) as well as use of vitamins (p=0.0001), herbals (p=0.006) and alternative therapy (p=0.0002) for cancer. Older age (>60) was associated with increased vitamin use (p=0.005) and decreased herbal use (p=0.008). Among users, 143 (20%) believed CAM assists healing, 123 (17%) believed CAM relieves symptoms, 122 (17%) believed CAM gives a feeling of control, 110 (15%) believed CAM assists other treatments, 108 (15%) believed CAM boosts immunity, 26 (4%) believed CAM cures cancer and 36 (5%) believed CAM prevents the spread of cancer.
