Associations Between Chemotherapy-Induced Nausea in Patients With Genitourinary, Sarcoma or Melanoma Cancers and Changes in Gut Microbiome: Potential for Precision Therapeutics

Investigation of Associations Between Chemotherapy-Induced Nausea in Patients With Genitourinary, Sarcoma or Melanoma Cancers and Changes in Gut Microbiome: Potential for Precision Therapeutics

The objective of this pilot cohort study is to investigate associations between CIN and changes in gut microbiome composition profiles.

The long-term goal of this study is to alleviate the occurrence of CIN and to improve chemotherapy treatment outcomes. The identification of associations between CIN and chemotherapy-induced changes in gut microbiome composition profiles will increase our understanding of these mechanisms that underlie CIN. An increased understanding of the underlying mechanisms will provide targets for the development of novel interventions to help alleviate CIN.
