Impact of Cooking Education and Adapted Physical Activity on Nutritional Status and Quality of Life of Patients Treated by Allo Stem Cell Transplantation

Bone marrow transplantation is the main strategy to cure leukemia and others hematopoietic malignancies. It includes a first step of chemotherapy during several days (combined sometimes to radiotherapy), a second step of stem cells infusion and a third step of management of complications during several months: side effects, infections or graft versus host disease (GvHD). Symptoms are cutaneous, hepatic and digestive (nausea, diarrhea, vomiting) and could be unfortunately followed by the death of the patients.

Nutritional status is known to be important during the treatment of all cancers. After bone marrow transplantation, patients could have some digestive disorders that could induce malnutrition that could have an impact of time of hospitalization, intensity of complications and outcome of these ones.

When patients go back home after allo stem cell transplantation, they take several medicines, they have digestive side effects of past treatments could alter mucous, taste and all digestive tracts. During at least 100 days, patients take immunosuppressive therapies and they are going to develop new immune system. Therefore, they must follow some food rules to avoid infectious diseases. Patients feel some difficulties to eat good food and refuse often social activities. All of these have an impact on quality of life and induce an increase of malnutrition observed already directly after allo stem cell transplantation. Some complications could also increase malnutrition like digestive GvHD or digestive infections. Malnutrition could also induce physical troubles. Patients need until one year to recover physical conditions before the disease.

The aims of the study are to improve nutritional status and physical activity of patients after allo stem cell transplantation.

The investigators propose at all patients included in the study cooking education and adapted physical activity every twice week in alternance. Cooking education will be performed by two famous chefs in their kitchens. Patients (until 3 months after bone marrow transplantation) and one member of their family are invited to cook and taste. They will receive lot of advice to make several recipes at home and will adapt their cooking methods to respect food rules. Adapted physical activity will be performed by a sportive coach at home. The coach will give them some physical exercises to do between two sessions.
