Successful Treatment of Cisplatin Overdose with Plasma Exchange

Abstract EN

Accidental cisplatin overdose has been occurring with an increasing frequency due to expanding usage of the agent.

However, the optimal strategy to treat such patients remains to be established.

Here, we report a case of large cisplatin overdose, successfully managed by plasma exchange, intravenous hydration, granulocyte colony-stimulating factor (G-CSF) administration, and other supportive care.

A 67-year-old man with esophageal carcinoma received a large cisplatin overdose of 240 mg/m2, when he received adjuvant therapy following subtotal esophagectomy.

On day 4, he experienced frank cisplatin toxicities and emergency plasma exchange was initiated.

With 7 cycles of plasma exchange, the cisplatin concentration decreased from 2,350 to 110 ng/mL.

Severe bone marrow suppression with high fever ensued on day 10, which was successfully treated with G-CSF and antibiotics.

Despite moderate hearing sense reduction, he recovered without significant complications.

Immediate plasma exchange with hydration and other care was efficacious in quickly lowering cisplatin concentrations.
