Abstract:
Colon cancer is one of the most common cancers and 5-fluorouracil (5-FU) has long been used as a primary chemotherapeutic agent. Lactic acidosis following systemic 5-FU exposure is rare. We report the case of a 36-year-old woman who developed lactic acidosis following mFOLFOX6 and FOLFIRI therapy for colon cancer with metastases to the liver, lungs, and brain. Two days after receiving 5-FU, the patient exhibited unconsciousness, convulsions, and a lactate level of 10 mmol/L. Her altered consciousness and convulsions improved with sodium bicarbonate treatment. In addition, we reviewed the relevant literature on lactic acidosis following 5-FU treatment in patients with colon cancer.
