[Complementary and alternative medicine use in two French pediatric oncology centers: A common practice]

Background: The use of complementary and alternative medicine (CAM) in children with cancer is commonly used. However, studies and data on this topic are still scarce in France.

Methods: Our aim was to investigate the prevalence of CAM usage in pediatric cancer patients and describe the modality of use. Our study population comprised children and young people treated from 2011 to 2012 in 2 French centers (Nantes, Paris). An anonymous self-administered questionnaire was addressed to families and data was collected from them and from the medical record.

Results: Out of the 202 patients selected for the study, 111 families answered the questionnaire (55%). Fifty-four (48.6%) of respondents reported CAM used. Forty-seven (87%) patients used CAM during initial therapy of cancer. Thirty-two (59.3%) of them talked about their CAM usage with health professionals, whose 25 (75.8%) with their oncologist. The three most common therapies used were homeopathy (75.8%), chiropractic (31.5%) and faith healing (42.6%). The main reason for the use of CAM was to control the side effects of conventional treatment (85.2%). Overall perceived satisfaction was rated 7.4/10.

Conclusion: The prevalence of complementary and alternative medicines administration is high, even if scientific evidence is limited regarding the effects, mechanisms of action and security of CAM. Research is necessary to improve the communication and council quality to the family, optimize supportive cares and reinforce the pharmacovigilance.
