This feasibility randomized controlled trial aims to evaluate the effectiveness and usability of a newly designed supportive corset for patients receiving continuous 5-Fluorouracil (5-FU) infusion therapy. The corset is intended to stabilize the infusion pump and serum set, reduce physical and psychological discomfort, and improve overall quality of life. Forty colorectal cancer patients were randomized into two groups: an intervention group using the corset and a control group receiving standard care. Outcomes include infusion-related experiences (measured by Visual Analog Scale) and quality of life (assessed by EORTC QLQ-C30).
