Fluorouracil Treatment Via Colon for Colorectal Cancer

Fluorouracil (5-FU) is a commonly used drug for colorectal cancer (CRC). Thermosensitive hydrogel presents a promising carrier for 5-FU to address challenges encountered with traditional administration methods. We propose an integrated approach utilizing colonic transendoscopic enteral tubing to cover the entire colon flexibly, coupled with a thermo-sensitive gel to enhance the adhesion of 5-FU. This clinical trial aims to assess the feasibility, safety, and efficacy of this approach for treating CRC.
