Summary

This study looks at whether eating more fiber helps melanoma patients respond better to immunotherapy. Researchers will track the fiber intake of 60 patients using a special questionnaire and see if those who eat more fiber have less cancer recurrence or progression. The goal is to understand the link between diet, gut bacteria, and treatment success.
