Prevalence of Complementary and Alternative Medicine-use by UK Cancer Patients: A Systematic Review of Surveys

Abstract

Background: Cancer patients seem to frequently use Complementary and Alternative Medicine (CAM). However, estimates of the level of usage vary widely. This systematic review is aimed at determining the prevalence of CAM-use in cancer patients of the United Kingdom (UK). Method: Five databases were searched for English language peer-reviewed surveys published between 01 January 2000 and 07 October 2011. In addition, relevant book chapters and our own departmental files were handsearched.

Results: 25 surveys were included with a total sample size of 6798. Across all studies, the median prevalence rate of CAM-use was 30.5 (standard deviation=10.3). Herbal medicine was the most popular CAM modality, followed by homeopathy, aromatherapy, reflexology and relaxation. Conclusions: Many UK cancer patients use CAM. Oncologists need to be aware of these numbers as they can impact daily practice on the management of cancer patients.
