Core Tip

Core Tip: Managing glycemic control and nutritional status is challenging in colorectal cancer patients with type 2 diabetes mellitus undergoing chemotherapy. This retrospective study demonstrates that adding personalized exercise training to standard care significantly improves glycemic control (reduced fasting plasma glucose, postprandial glucose, glycosylated hemoglobin, and variability), enhances nutritional biomarkers (albumin, prealbumin, hemoglobin, transferrin), and positively modulates intestinal permeability markers (zonulin, occludin) compared to standard care alone. Individualized exercise training was safe, with no increased adverse events. Personalized exercise is a beneficial adjunctive therapy for improving metabolic and nutritional outcomes in this high-risk population during chemotherapy.
