Complementary therapies in cancer patients: prevalence and patients' motives.

BACKGROUND

Data relating to the use of complementary/alternative medicine (CAM) in cancer patients have been published for a number of European countries. No recent data are available for Austria.

AIM

To ascertain the extent of CAM use by cancer patients, what patients' motives are, what methods are used and who the CAM providers are.

DESIGN

Self-administered questionnaire; cross-sectional study.

PATIENTS AND METHODS

A sample of 231 cancer patients who had consulted the Viennese Cancer League. Chi-square and Mantel-Haenszel tests were used for the statistical evaluation.

RESULTS

27.3% of the cancer patients had received CAM therapy: 33.1% of the female and 20.5% of the male participants (p = 0.045). Those who were below the median of the age categories (53.8 years) had used CAM to a statistically higher degree (35.5% vs. 21.1%; p = 0.023). The most important motives were the enhancement of "nature" and the GPs' recommendation. CAM was administered in 44.4% of cases by the family doctor, in 39.7% by patients themselves, in 6.3% by a hospital doctor, in 6.3% by a lay-practitioner or "non-medical practitioner against payment" and in 4.8% of cases by a practising oncologist.

CONCLUSION

From the high percentage of patients who use CAM without consulting a physician or who follow the advice of others, it would seem highly probable that conventional and complementary methods are rarely effectively coordinated. To rectify this we conclude that oncologists and GPs should have a basic knowledge of CAM and address the issue when counselling their cancer patients.
