Leucovorin calcium, 5-fluorouracil, and oxaliplatin (FOLFOX) therapy is a standard chemotherapy regimen used to treat colorectal cancer. Peripheral nerve disorder and myelosuppression are frequently reported treatment-related adverse events. With modified FOLFOX6 (mFOLFOX6) therapy, adverse events of an altered mental state with reversible posterior leukoencephalopathy and hypoammonemia have been reported, while lactic acidosis is uncommon. We describe a case of mFOLFOX6 - induced lactic acidosis in a 64-year-old man with colorectal cancer who underwent pelvic exenteration following chemotherapy. Postoperative histopathological analysis revealed residual cancer. Following the commencement of mFOLFOX6 therapy, the patient experienced emesis, hiccupping, and an altered mental state. Laboratory testing revealed only severe lactic acidosis, while diagnostic imaging was unrevealing. All symptoms quickly improved upon the administration of intravenous infusion of sodium bicarbonate.
