Influence of a High-fiber Diet on the Microbiota and the Response to Immunotherapy in Patients Treated for Melanoma.

The underlying hypothesis of the study is that melanoma patients treated with immunotherapy, whether in an adjuvant or curative setting, who consume more fiber would respond better to immunotherapy: either no recurrence in the case of adjuvant treatments, or no progression (disease stability, partial or complete response) in the case of curative treatments. The primary objective is to evaluate the association between total dietary fiber intake quantified using the FiberTAG questionnaire and response to immunotherapy treatment in patients treated for melanoma in a curative or adjuvant setting
