5-Hydroxyindoleacetic acid (5-HIAA) and cortisol excretion as predictors of chemotherapy-induced emesis

Abstract

This study evaluated the relationship between prechemotherapy cortisol and 5-hydroxyindoleacetic acid (5-HIAA) excretion and chemotherapy-induced emesis. The urinary excretion of cortisol and the serotonin metabolite 5-HIAA in the night before chemotherapy administration were measured in 28 and 49 female patients receiving > 300 mg m-2 carboplatin. Vomiting and nausea were documented over a 3 day observation period. Lower basal cortisol excretion was significantly correlated with vomiting with or without nausea occurring within the observation period. 5-HIAA showed only a weak correlation with emesis on days 1-3, but low 5-HIAA excretion was correlated with a higher proportion of patients vomiting on days 2-3 following chemotherapy. Low basal cortisol excretion might be useful as a predictor for chemotherapy-induced emesis and therefore should be evaluated prospectively in future studies.
