Successful Treatment of Cisplatin Overdose with Plasma Exchange

We report a 48-year-old man with laryngeal cancer who received a massive cisplatin toxic overdose without intravenous prehydration through an error in prescription. He received 400 mg/m² of cisplatin over a 4-day period. On day 4, he exhibited a broad range of cisplatin toxicities and emergency plasma exchange was started. From day 5 through 19, he underwent 9 cycles of plasma exchange and his plasma cisplatin concentration decreased from 2,470 ng/ml to 216 ng/ml. He completely recovered without any sequelae. No previous reports exist in the English literature of survival without complication after the administration of such a high cisplatin dosage without prehydration.
