Complementary and alternative medicine use among patients with cancer in Mongolia: a National hospital survey.

Background: Complementary and alternative medicine (CAM) use is popular in former Soviet Central Asian countries including Mongolia. However, no studies are available on CAM use among patients with cancer in countries of this region. The aim of this research is to describe the prevalence and patterns of CAM use by patients with cancer in Mongolia.

Methods: A cross-sectional study was conducted using data from 482 cancer patients attending the National Cancer Center in Mongolia from September 2015 to February 2016. The survey instrument included 25 questions regarding CAM used, factors associated with use of CAM, cancer-related characteristics, and participants' socio-demographic profile.

Results: Among 482 respondents (response rate, 95.6%), 47.9% reported using one or more CAM modalities. Products of animal origin were the most popular modalities of CAM, followed by herbal products. Half of the users used CAM while receiving conventional treatment of cancer. Among users, only 29% discussed the CAM use with their doctors. Female gender, younger age, higher education, shorter disease duration, and prior use of CAM were significantly associated with CAM use.

Conclusions: CAM appears to be widely accepted by patients with cancer in Mongolia. The findings support the urgent need for further in-depth study into commonly used oral CAM products and their potential effects on health of patients with cancer in Mongolia. High prevalence of CAM use among cancer patients in our study warrants further studies in other countries of Central Asia.
