Histidine Supplementation for Antitumor Immunity in Colorectal Cancer
A Single-arm Clinical Study of Histidine Supplementation for Antitumor Immunity in Colorectal Cancer
The goal of this clinical study is to learn whether oral histidine supplementation may be safely used to support antitumor immune function during standard colorectal cancer treatment.
Participants with colorectal cancer in the supplementation group will:
Take 2g oral histidine once daily during standard colorectal cancer treatment; Provide blood samples before and after supplementation; Attend regular follow-up visits for laboratory tests, safety assessment, and treatment evaluation.
