RESUMO
AIM AND BACKGROUND: Intestinal alkalization could prevent irinotecan associated diarrhea modulating some chemical equilibria between irinotecan metabolites. The aim of this study was to evaluate the efficacy of this procedure in advanced gastrointestinal cancer patients (GICP). MATERIALS AND METHOD: In this prospective study advanced GICP, receiving irinotecan based chemotherapy regimens, were well trained to add sodium bicarbonate to the water intake in order to accomplish intestinal alkalization. RESULTS: A total of twenty four advanced GICP were enrolled. Grade III-IV diarrhea has been observed in four patients (16%), some of whom had several risk factors for diarrhea. Only one out of seventeen colorectal cancer patients, receiving the irinotecan combination as first line therapy, had grade III-IV diarrhea. No side effects of the procedure have been appreciated. CONCLUSIONS: Intestinal alkalization may be effective as a preventive treatment for irinotecan associated diarrhea in chemotherapy regimens used in GICP. This procedure deserves further investigation.
