Summary
Elevated ferritin levels (≥100 ng/mL) in patients receiving 5-fluorouracil (5-FU) chemotherapy may indicate potential cardiotoxicity and treatment failure. Routine iron studies are recommended alongside echocardiography for monitoring.
Area of Science:
- Oncology
- Cardiology
- Biochemistry
Background:
- Fluoropyrimidines, like 5-fluorouracil (5-FU), are vital in treating gastrointestinal cancers but are linked to cardiotoxicity.
- The exact mechanism of 5-FU-induced cardiotoxicity is unclear, though studies show increased myocardial iron in rat models.
