Capecitabine-induced cerebellar toxicity in a patient with metastatic colorectal cancer.

INTRODUCTION: Capecitabine is an oral fluoropyrimidine that was designed to allow selective activation in tumour tissues, thus reducing toxicity. The neurologic toxicity of 5-fluorouracil, the original fluoropyrimidine, including an ataxic cerebellar syndrome is well described. However, only a few case reports exist describing a similar syndrome associated with capecitabine administration. CASE REPORT: We report a case of reversible cerebellar toxicity during chemotherapy with a combination of capecitabine and oxaliplatin. DISCUSSION: Rare fluoropyrimide-related toxicities are increasingly being reported in association with capecitabine. Clinical vigilance is required to ensure appropriate investigation and treatment.
