Abstract
Amifostine has emerged as a pancytoprotectant shown protection against nephrotoxicity, neurotoxicity and ototoxicity in preclinical studies. Methods: We designed a prospective comparative randomized trial to evaluate the cytoprotective effects of amifostine in patients with osteosarcoma receiving cisplatin and doxorrubicin. Patients were evaluated for renal, hearing and cardiac toxicity. Results: We included 28 patients, mean age was 11.6 years, five had metastatic disease. Fifteen patients received amifostine and 13 did not. 20% of patients receiving amifostine developed renal toxicity compared to 30% in the control group (p = 0.318). Grade 1 and 2 audiologic toxicity was present in 100% of the experimental group against 85% of the controls (p = 0.501). Grade 1 cardiac toxicity was present in 2 patients in the control group (p = 0.175). There were no statistical significant differences between the two groups for chemotherapy-related toxicity. Response to chemotherapy was significantly better in the amifostine group. Conclusion: amifostine did not reduce the ototoxicity and nephrotoxicity of our treatment regime. It was not well tolerated due to emesis. It is a selective cytoprotectant without reducing the effect of chemotherapy.
