NCT ID NCT07315412
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether chewing ginger-mint or cinnamon gum can reduce nausea and vomiting after a specific chemotherapy procedure (PIPAC) for colorectal cancer that has spread to the abdomen. 75 adults will be randomly assigned to chew one of the two flavored gums or receive standard care only. The goal is to find a simple, drug-free way to improve comfort and recovery after treatment.
