AbstractThe purpose of this study was to investigate the feasibility and efficacy of pirarubicin (THP)-cisplatin (DDP) chemotherapy for refractory and recurrent high-grade osteosarcoma. Between 2008 and 2010, 23 patients with refractory and recurrent high-grade osteosarcoma were included in this analysis. THP was given at a dose of 50 mg/m(2) i.v. d1 and DDP 100-120 mg/m(2) i.v. d2-3 every 3 weeks. Treatment was continued until evidence of disease progression or unacceptable toxicity. Tumor response was usually evaluated every two chemotherapy cycles by CT/MRI scan. The primary end point was overall response rate, secondary endpoint including progression-free survival (PFS), overall survival (OS), disease control rate, and toxicities. A total of 68 cycles were given, median 2 per patient (range 2-7). Overall response rate was 13% and disease control rate was 34.5%, with 3 partial responses and 5 stable diseases. Median time to progression and overall survival time were 2 (95%CI 2-11) and 10 months (95%CI 6-23), respectively. Major severe toxicities were grade 3 or 4 leucopenia occurred 12 times (17.7%) in total cycles; Mild toxicities included grade 1 or 2 nausea and vomiting (80.9%), leucopenia (61.8%), fatigue (50.0%), and alopecia (79.4%). THP-DDP regimen chemotherapy represents an active and well-tolerated treatment for Chinese refractory and recurrent high-grade osteosarcoma patients. Further assessment is necessary to confirm the safety and efficacy of this treatment.
