Summary
Continuous infusion 5-fluorouracil caused angioneurotic edema in a patient with oral cancer and cirrhosis. Standard allergy treatments failed, leading to fatal disease progression after chemotherapy was stopped.
Area of Science:
- Oncology
- Pharmacology
- Immunology
Background:
- A patient with recurrent oral cavity carcinoma, cirrhosis, and cisplatin-induced renal impairment received continuous infusion 5-fluorouracil chemotherapy.
- The patient had a history of complex medical conditions, including liver cirrhosis and kidney dysfunction.
Observation:
- An allergic reaction, specifically angioneurotic edema, manifested during the sixth and seventh cycles of chemotherapy.
- The allergic reaction was a severe adverse event associated with the administration of 5-fluorouracil.
- Attempts to manage the reaction with oral diphenhydramine and prednisone were unsuccessful in preventing recurrence.
Findings:
- Continuous infusion 5-fluorouracil can induce severe allergic reactions like angioneurotic edema.
- Standard antihistamine and corticosteroid treatments may be ineffective for chemotherapy-induced allergic reactions.
- Discontinuation of effective chemotherapy due to adverse events can lead to poor patient outcomes.
Implications:
- Clinicians should be vigilant for allergic reactions during 5-fluorouracil chemotherapy, especially in patients with comorbidities.
- Alternative chemotherapy regimens or desensitization protocols may be necessary for patients experiencing severe allergic reactions.
- Managing adverse drug reactions is critical for maintaining treatment continuity and improving survival in cancer patients.
