IV Ascorbic Acid in Peritoneal Metastatic Colorectal Cancer

Previous preclinical study has shown that high levels of ascorbic acid (AA) possesses the ability to kill human colorectal cancer cells and high expression of GLUT3 will augment the efficacy of AA. To date, no previous studies have investigated the therapeutic role of AA in peritoneal metastatic colorectal cancer with high expression of GLUT3. This protocol is a randomized controlled study of AA infusions combined with FOLFOXIRI +/- bevacizumab versus treatment with FOLFOXIRI +/- bevacizumab alone in peritoneal metastatic colorectal cancer patients with high expression of GLUT3.
