A rare intoxication caused by the prolonged, low-dose administration of 5-fluorouracil, which is the mainstay of both adjuvant and advanced-disease chemotherapy regimens in colon cancer. 5-fluorouracil poisoning is characterized by gastrointestinal (nausea, emesis, diarrhea, anorexia, stomatitis) and hematologic (myelosuppression) toxicities as well as mucositis, alopecia and, occasionally, palmar-plantar dysesthesia (more commonly known as hand-foot syndrome). Women have been reported to experience more 5-fluorouracil-related toxicity than men.
