Background: Intestinal dysfunction is frequent in cancer and during anti-cancer treatment. Glucagon-like peptide-2 (GLP-2) is secreted in a nutrition-dependent manner from the intestinal enteroendocrine L-cells. It accelerates crypt cell proliferation and nutrient absorption, inhibits enterocyte apoptosis and decreases mucosal permeability. Lack of GLP-2 may increase the risk of malabsorption and intestinal bacterial translocation. The aim of this study is to evaluate meal stimulated secretion of GLP-2 in children with cancer undergoing anti-cancer treatment.

Methods: Plasma-GLP-2 analysis after an overnight fast and 1 hour after intake of a mixed test meal. Data on gastrointestinal toxicity, blood neutrophile counts and food records were included in the analysis.

Results: Forty-four meal stimulation tests were performed in 25 children (median age, 6.0 years; range, 2.5-19) during anti-cancer treatment. Median GI toxicity score was 5 (range, 0-15), and mean energy intake was 62.4% of recommended values. P-GLP-2 values increased from mean (SD) 38 (18) to 63 (51) pmol/l (P < 0.0001). Twelve of the meal stimulation tests (28%) resulted in a p-GLP-2 increase >2 fold, which is assumed to be the lower limit of normal values. The increase was strongly dependent on the energy intake (r = 0.62, P < 0.0001), while toxicity score and neutrophile count had no significant influence (multiple regression).

Conclusion: In children treated with anti-cancer therapy, GLP-2 secretion seems to be normal if the enteral energy intake is sufficient. Insufficient GLP-2 secretion could influence the gastrointestinal problems seen in the children with a low enteral energy intake.
