Combination Chemotherapy, Surgery, and Radiation Therapy in Treating Children With Advanced Soft Tissue Sarcoma

Combination Chemotherapy, Surgery, and Radiation Therapy in Treating Children With Advanced Soft Tissue Sarcoma

Phase II Study of Neoadjuvant Vincristine, Ifosfamide, Doxorubicin, and AND G-CSF in Children With Advanced Stage Non-Rhabdomyosarcoma Soft Tissue Sarcomas

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining more than one chemotherapy drug with radiation therapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, surgery, and radiation therapy in treating children who have advanced soft tissue sarcoma.

OBJECTIVES: I. Assess the response to vincristine/ifosfamide/doxorubicin (VID) with granulocyte colony-stimulating factor support in children with newly diagnosed, inoperable or metastatic non-rhabdomyosarcoma soft tissue sarcomas. II. Estimate the 2-year and event-free survival rates in children treated with VID plus radiotherapy and/or surgery. III. Establish a bank of frozen tumor and peripheral blood tissue for use in further molecular studies. OUTLINE: The following acronyms are used: DOX Doxorubicin, NSC-123127 G-CSF Granulocyte Colony-Stimulating Factor (Amgen), NSC-614629 IFF Ifosfamide, NSC-109724 Mesna Mercaptoethane sulfonate, NSC-113891 VCR Vincristine, NSC-67574 VID VCR/IFF/DOX Induction: 3-Drug Combination Chemotherapy. VID. Local Control: Surgery and/or Radiotherapy plus 3-Drug Combination Chemotherapy. Excision of the primary tumor and pulmonary metastases; and/or irradiation of the primary tumor and pulmonary metastases using x-rays or Co60 beam energies of at least 4 MV (electrons or iridium-192 implant allowed for boost); plus VID. Continuation: 3-Drug Combination Chemotherapy. VID. PROJECTED ACCRUAL: A total of 40 patients will be entered over 2.7 years if there are at least 7 responses in the first 20 patients.

Induction (Weeks 1-6) Vincristine sulfate (1.5 mg/m2) day 1, Ifosfamide (3 grams/m2) days 1-3, Doxorubicin (30 mg/m2) days 1-2, filgrastim day 4. Weeks 2 and 3 - Vincristine sulfate (1.5 mg/m2) IV day 1, week 5 no chemotherapy. Evaluate for response. Local Control (Weeks 7-13) Conventional surgery and radiation therapy. Vincristine sulfate (1.5 mg/m2) IV day 1, Ifosfamide (3 grams/m2) days 1-3, Doxorubicin (30 mg/m2) days 1-2, filgrastim day 4. Treatment continues per protocol.

Estimate the response rate to the combination of vincristine, ifosfamide, and doxorubicin (VID), with G-CSF support

To estimate the response rate to the combination of vincristine, ifosfamide, and doxorubicin (VID), with G-CSF support, in children with newly diagnosed inoperable or metastatic non-rhabdomyosarcoma soft tissue sarcomas.

To estimate the 2-year survival and event-free survival of children treated with VID in combination with radiotherapy and/or surgery

To establish a bank of frozen tissue (tumor and peripheral blood) for use in further molecular studies.
