Abstract
The outcomes of osteosarcoma with poor prognostic factors, such as poor responders, metastatic disease at diagnosis, and relapsed or refractory disease, are poor. We reviewed the clinical records of the patients diagnosed with osteosarcoma at our institute between 2004 and 2018 who received high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) in our institute. Ten patients of osteosarcoma with poor responder, refractory status, and metastatic disease at diagnosis received high-dose chemotherapy followed by ASCT. Four patients underwent high-dose chemotherapy followed by ASCT with the conditioning regimen consisted of thiotepa and melphalan (MEL). Five patients underwent high-dose chemotherapy followed by ASCT with the conditioning regimen consisted of intravenous busulfan (BU) and MEL. One patient underwent tandem high-dose chemotherapy followed by ASCT with BU and MEL followed by carboplatin and etoposide. None of the ten patients died of regimen related toxicities. None of the five patients with poor responders who underwent high-dose chemotherapy followed by ASCT as part of consolidation therapy died of disease after ASCT. High-dose chemotherapy followed by ASCT might be effective for poor responder...Continue Reading
