Currently, Morocco provides several therapeutic tools for cancer, among them chemotherapy, surgery and radiotherapy. In Morocco, there is not enough published data on the use of alternative medicine in pediatric oncology. Owing to the increased interest and lack of data on this practice, we conducted this study. It aims to evaluate the uptake, the types of therapies used, the factors influencing, the reasons for this choice and the cost of AM used by patients. An investigation through a questionnaire was carried out on thirty-four children following for cancer within the pediatric hematology and oncology department (PHO) of Marrakech. The survey was conducted over a period of one month and a half between July 25 and September 5, 2022. Data were collected through a questionnaire. From the medical files, we collected data regarding type of cancer, date of admission to PHO department and the treatment received. We asked about the type of AM used: herbs, honey, spiritual AM, zamzam water (water from a “sacred” source in Mecca). Using alternative therapies is a common practice in pediatric oncology with various reasons, among them, the declining socioeconomic level, the diversity, the cultural background, the psychological and the functional status of patients and sometimes the dissatisfaction with conventional medicine.展开更多
