Use of Complementary and Alternative Medicines among Cancer Patients: A Single-Center Study.

It is usual for cancer patients to use complementary and alternative medicines (CAMs) and yet the literature evaluating their efficacy in cancer patients is very limited. The objective of the present study was to report on the nature, frequency of use, and patient-reported outcome of CAMs in a single-center study. All the consecutive patients treated between November 2017 and June 2018 at the Lucien Neuwirth Cancer Institute (France) were screened. Their reasons for using CAMs and their usage habits were collected. Patients evaluated their benefit. Of the 209 patients screened, 200 patients were included. CAMs ranged from osteopathy, homeopathy, acupuncture, healing touch, magnetism, naturopathy, suction cups, Chinese medicine, reflexology, to hypnosis. CAMs were widely used (n = 166, 83%), the first being osteopathy (n = 99, 49.5%), the second homeopathy (n = 78, 39.0%), and finally acupuncture (n = 76, 38.0%). Whatever the CAM, high satisfaction rates were reported (median satisfaction: 61-81%). CAMs were mainly used to prevent/treat side effects of anticancer treatments (81.2% for healing touch), increase well-being (55.4% for naturopathy), improve the immune system (16.9% for homeopathy), and treat cancer (n = 3, 5.1% for homeopathy). Patients could easily consider using CAMs, as up to 50.8% would have accepted a consultation. The reasons for using CAMs differed among patients. They praised CAMs and kept asking for more information although there is limited evidence about their efficacy in the literature. Thus, prospective randomized controlled trials exploring the safety and efficacy of CAMs in cancer patients are needed.
