  • CCG-0924: PIXY 321 at doses of 500/750/1000 mcg/m² SC once per day or 500 mcg/m² SC twice per day, starting on day 5 and to continue until day 18 unless ANC reached 20,000/μL or platelet count is at least 900 x 10⁹/L for 2 days between days 13 to 18, or until ANC is at least 1000/μL and platelet count is at least 100 x 10⁹/L, whichever comes later

Chemotherapy

• Vincristine (Oncovin) 2 mg/m² IV once on day 1

• Dactinomycin (Cosmegen) 1.25 mg/m² IV once on day 1, once cumulative doxorubicin dose received by the patient exceeds 375 mg/m²

21-day cycle for 17 cycles

Local therapy

Local therapy is planned to take place on week 9, as follows:

• Surgical removal of tumors is done when possible.
• External beam radiotherapy to all metastatic sites of disease in addition to any radiation planned for primary tumor.
• If only radiation therapy is used, External beam radiotherapy 4500 cGy is administered to the tumor volume plus a 3 cm margin, followed by 1080 cGy to only the preradiation tumor volume, for a total dose of 5580 cGy
• Residual tumor after surgery and lung metastases are treated with "dose-volume guidelines for gross residual disease"
