Use of complementary and alternative medicine by cancer patients at the University of Nigeria Teaching Hospital, Enugu, Nigeria.
BACKGROUND
The use of Complementary and Alternative Medicine (CAM) by cancer patients is very common and varies between populations. The referenced English literature has no local study from Africa on this subject. This study was conducted to define the prevalence, pattern of use, and factors influencing the use of CAM by cancer patients at the University of Nigeria Teaching Hospital Enugu (UNTH-E), Nigeria


METHODS
Face-to-face interviews using semi-structured questionnaire were used to determine the use of CAM by cancer patients. All consenting cancer patients were interviewed as they presented at the core surgical units of the UNTH- E, from June 2003 to September 2005.


RESULTS
160 patients were interviewed; 68 (42.5%) were males and 94 (57.5%) were females. Ages ranged from 13-86 years. Breast, urogenital system, gastrointestinal system, and soft tissue cancers predominated. One hundred and four patients (65.0%) have used CAM at some time during their current cancer illness; 56 (35.0%) patients have not used any form of CAM. There were more females than males among the non-CAM users. The use of CAM was not affected by age, marital status, level of education, religious affiliation, or socioeconomic status. The most frequently used CAMs were herbs (51.9%), faith/prayer healing (49.4%), aloe vera (23.1%), Forever Living Products (16.3%), medicinal tea (14.4%), and Blackstone (12.5%). Over 23% of those who used CAM were satisfied, but 68.3% were disappointed. Most users (67.3%) did not see any benefit from the CAM, but 25% could describe some specific benefits. More than 21% of users reported various unwanted effects. While 86.5% of CAM users will use orthodox medicine instead of CAM in the future, 9.6% will use the two together to help each other. Most users (79.8%) will not repeat CAM or recommend its use for cancer. The majority of patients (55.8%) did not mention their use of CAM to their doctors - mostly because the doctor did not ask.


CONCLUSIONS
CAM use is common among cancer patients in Nigeria. Most users do not obtain the expected benefits, and adverse events are not uncommon. Every clinician in the field of oncology should ask his/her patients about the use of CAM; this knowledge will enable them to better counsel the patients.
