Suramin therapy for cancer can cause severe polyneuropathy, a nerve disorder. Monitoring suramin blood levels is recommended to prevent this neurotoxicity risk.

Area of Science:

  • Neuroscience
  • Oncology
  • Pharmacology

Background:

  • Suramin is an investigational antineoplastic agent.
  • Severe polyneuropathy is a potential adverse effect of suramin therapy.

Purpose of the Study:

  • To report the development of polyneuropathy in patients treated with suramin.
  • To investigate the correlation between suramin plasma levels and neurotoxicity.

Main Methods:

  • Observational study of 38 patients receiving parenteral suramin.
  • Electromyography (EMG) and nerve conduction studies were performed.
  • Cerebrospinal fluid (CSF) protein levels were monitored.

Main Results:

  • Four of 38 patients developed polyneuropathy, with two experiencing severe paralysis.

  • Neuropathy correlated with maximum plasma suramin levels (≥350 µg/ml).
  • Elevated CSF protein was observed during the acute phase of neuropathy.

    • Conclusions:

    • Suramin can induce severe sensorimotor polyneuropathy.
    • Neurotoxicity appears related to plasma concentration, not total dose or duration.
    • Serial monitoring of plasma suramin levels is recommended during treatment.
