Emergency treatment of severe fluorouracil toxicity

Emergency treatment of severe fluorouracil toxicity refers to urgent therapeutic intervention for life-threatening acute poisoning or systemic overexposure to fluorouracil (or its prodrug capecitabine) This critical state arises in adult or pediatric oncology patients following an accidental chemotherapy overdose or from standard dosing in patients with impaired drug clearance, most notably congenital dihydropyrimidine dehydrogenase (DPD) deficiency It affects multiple rapidly dividing tissues a...

Emergency treatment of severe fluorouracil toxicity refers to urgent therapeutic intervention for life-threatening acute poisoning or systemic overexposure to fluorouracil (or its prodrug capecitabine) Clinically, it manifests as early-onset, severe encephalopathy, acute cardiotoxicity, intractable gastrointestinal mucositis or diarrhea, and life-threatening myelosuppression, demanding rapid intervention to prevent fatal multi-organ failure

This critical state arises in adult or pediatric oncology patients following an accidental chemotherapy overdose or from standard dosing in patients with impaired drug clearance, most notably congenital dihydropyrimidine dehydrogenase (DPD) deficiency Clinically, it manifests as early-onset, severe encephalopathy, acute cardiotoxicity, intractable gastrointestinal mucositis or diarrhea, and life-threatening myelosuppression, demanding rapid intervention to prevent fatal multi-organ failure

It affects multiple rapidly dividing tissues and vital organ systems, characterized pathophysiologically by profound antimetabolite-induced cellular damage

Clinically, it manifests as early-onset, severe encephalopathy, acute cardiotoxicity, intractable gastrointestinal mucositis or diarrhea, and life-threatening myelosuppression, demanding rapid intervention to prevent fatal multi-organ failure
