Epileptic seizures associated with cisplatin administration.

Area of Science:

• Oncology
• Neuroscience

Background:

• Cisplatin is a cornerstone chemotherapy agent for germ cell tumors and ovarian carcinoma.
• Neurotoxicity is a known side effect of platinum-based chemotherapy, but seizures are rare.

Purpose of the Study:

• To investigate the occurrence of epileptic seizures in patients treated with cisplatin-containing chemotherapy.
• To identify potential risk factors associated with cisplatin-induced seizures.

Main Methods:

• Retrospective analysis of 81 patients with germ cell tumors or ovarian carcinoma treated with cisplatin-based chemotherapy over 4 years.
• Documentation of seizure events occurring during or within 3 months of chemotherapy.
• Assessment of potential contributing factors including hyponatremia and renal function.

Main Results:

• Eight patients (9.8%) experienced epileptic seizures.
• Seizures occurred during or within 3 months of chemotherapy.
• Potential contributing factors identified include hyponatremia and impaired renal function.

Conclusions:

• Cisplatin-containing chemotherapy may be associated with an increased risk of epileptic seizures in patients with germ cell tumors and ovarian carcinoma.
• Hyponatremia and pre-existing renal impairment may predispose patients to seizures.
• Further investigation is warranted to establish a definitive causal link and elucidate mechanisms.
