title: Doxorubicin and cisplatin with granulocyte colony-stimulating factor as adjuvant chemotherapy for osteosarcoma: phase II trial of the European Osteosarcoma Intergroup.
abstract: OBJECTIVE
  This report describes the toxicity and feasibility of administering doxorubicin (DOX) and cisplatin (CDDP) at 2-week intervals with granulocyte colony-stimulating factor (G-CSF) to patients with osteosarcoma and the compatibility of this regimen with endoprosthetic surgery performed after three cycles.
  
  
  METHODS
  Twenty-four patients with biopsy-proven osteosarcoma were treated with three preoperative cycles of DOX 25 mg/m2/d on days 1 to 3 and CDDP 100 mg/m2 on day 1 with G-CSF 5 micrograms/kg/d on days 4 to 14. Surgery was scheduled at week 6 to be followed by three further cycles of chemotherapy at 2-week intervals.
  
  
  RESULTS
  Two-week chemotherapy was feasible, but delays and dose reductions only allowed 74% and 78% of the intended dose-intensity of DOX and CDDP to be administered. Thrombocytopenia accounted for 50% of delays. Significant toxicity included neutropenic sepsis, severe mucositis, prolonged nausea and vomiting, and electrolyte disturbances. Twenty-one limb-salvage procedures and one amputation were performed. There were eight episodes of excessive perioperative bleeding.
  
  
  CONCLUSIONS
  Intensive 2-week chemotherapy with intercurrent surgery is feasible and allows a greater dose-intensity of chemotherapy to be administered compared with the same regimen administered at 3-week intervals without G-CSF. The toxicity is considerable, but manageable.
