Cisplatin (CDDP) is a potent anticancer drug, and neurotoxicity is one of its most important dose-limiting toxicities. In this study we investigated the role of recombinant human erythropoietin (rhuEPO) for protection against CDDP-induced neurotoxicity. All experiments were conducted on female Wistar-albino rats. Animals were randomly assigned to three groups. Group A received only CDDP, group B received CDDP plus rhuEPO, and group C received only rhuEPO. Electroneurography (ENG) was done in the beginning and at the end of 7 wk, then the rats were sacrificed and the sciatic nerve was removed for histopathological examination. The mean initial latency was 2.7438 ms in group A, 2.4875 ms in group B, and 2.62 ms in group C. After 7 wk of treatment, the latency was 2.4938, 2.6313, and 2.3900 ms, respectively. The difference in latencies was not statistically significant. The amplitude of compound muscle action potential (CMAP) was 12.8125 mV, 14.3875 mV, and 14.5600 mV before the treatment and 8.4875, 12.8250, and, 13.0800 mV after treatment, respectively. Amplitude of CMAP was significantly greater in rhuEPO-treated groups (groups R and C) compared to cisplatin only Group A. The mean area of CMAP was 12.2625, 12.3500, and, 12.2800 mV s before the treatment and 5.7125, 10.6463, and 9.1600 mV s after the treatment, respectively. The area of CMAP was significantly larger in rhuEPO-treated groups. In histopathological studies thick, thin, and total number of nerve fibers were 4053, 5050, and 9103, in group A, 5100, 823 1, and 13331 in group B, and 5264, 6010, and 11274, in group C respectively. In the microscopic examination active myelinization process was observed in rhuEPO-treated groups. We concluded that at the given dose and schedule CDDP-induced motor neuropathy and rhuEPO prevented this neuropathy by sparing the number of normal nerve fibers and by protecting the amplitude and area of CMAR We concluded that rhuEPO may also play a role in active myelinization and it is an active agent in protection against CDDP-induced peripheral neuropathy, warranting further clinical studies.
