Filter by:RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining chemotherapy with biological therapy may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy with or without biological therapy in treating patients who have newly diagnosed high-risk Ewing's sarcoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Radiation therapy uses high-energy x-rays to damage tumor cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy, peripheral stem cell transplantation, and radiation therapy in treating patients with recurrent metastatic Ewing's sarcoma, peripheral primitive neuroectodermal tumor, or rhabdomyosarcoma.
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 drug with surgery and radiation therapy may kill more tumor cells. It is not yet known which combination chemotherapy regimen is most effective in treating patients with Ewing's sarcoma. PURPOSE: Randomized phase III trial to compare various combination chemotherapy regimens plus surgery and radiation therapy in treating patients who have Ewing's sarcoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug or combining chemotherapy with radiation therapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by radiation therapy in treating patients with peripheral neuroectodermal tumors, Ewing's sarcoma, Wilms' tumor, or bone cancer.
This protocol is designed to evaluate children with cancer who appear to be probable candidates for future protocol entry or have disease manifestations that are of unique scientific importance or educational value.
This is a single arm study. The tumor specimen is analyzed for the presence of a fusion protein which corresponds to available peptides. Patients undergo T cell harvest 10 days after an initial priming peptide-pulsed antigen presenting cell (APC) vaccine is performed. Fresh APCs are utilized for initial priming vaccination. All subsequent vaccinations will use cryopreserved APCs. Minimum number of APCs administered per vaccination is 100,000/kg and maximum is 100,000,000/kg. Patients undergo cytoreductive therapy for the treatment of their particular malignancy. This therapy usually consists of multiagent chemotherapy in the context of a separate protocol. Following chemotherapy, infusion of harvested T cells followed by infusion of peptide-pulsed APC vaccinations occurs every 6 weeks for a total of 3 post-priming vaccinations. Influenza vaccine is administered by intramuscular injection concurrent to peptide-pulsed APC vaccines. Interleukin -2 (IL-2) is administered as a continuous intravenous (IV) infusion for 4 days/week for 3 successive weeks starting on the same day as T cell /peptide-pulsed infusions.
Arm A: Peripheral blood apheresis by harvesting chemotherapy-naive T cells and populations enriched for professional APCs. T cells and APCs are separated from the apheresis product using countercurrent centrifugal elutriation and a monocyte rich fraction is collected. Autologous T cell transplantation during immunotherapy. Arm B: Cell harvesting is performed as soon as possible. Both Arm A and B: Patients receive intravenous infusion of irradiated peptide-pulsed antigen presenting cell vaccination (APC) products as well as intramuscular injection of influenza vaccine on the same day. Recombinant human IL-2 is administered within 4 hours of the peptide pulsed vaccine by continuous intravenous infusion for 4 days per week for 3 successive weeks. Primary toxic effect of this therapy is expected to be related to the IL-2 therapy. Patients with Grade 2 neurologic or cardiac or any Grade 3 or 4 toxic effects will discontinued IL-2 therapy. If toxic effect is not resolved in 72-hours, the patient may remain on study but will not receive any further IL-2.
The prognosis for patients with metastatic Ewing's sarcoma family of tumors (ESF), rhabdomyosarcoma (RMS), and neuroblastoma (NBL) remains dismal, with less than 25% long-term disease-free survival. Though less grave, the prognosis for cure for other high-risk patients is approximately 50%. New treatment strategies, including the identification of highly active new agents, maximizing the dose intensity of the most active standard drugs, and the development of improved methods of consolidation to eradicate microscopic residual disease, are clearly needed to improve the outcome of these patients. This protocol will address these issues by commencing with a Phase II window, for the highest risk patients, to evaluate a series of promising drugs with novel mechanisms of action. All patients will then receive 5 cycles of dose-intensive "best standard therapy" with doxorubicin (adriamycin), vincristine, and cyclophosphamide (VAdriaC). Patients at high risk of relapse will continue onto a phase I consolidation regimen consisting of three cycles of dose-escalated Melphalan, Ifosfamide, Mesna, and Etoposide (MIME). Peripheral blood stem cell transfusions (PBSCT) and recombinant human G-CSF will be used as supportive care measures to allow maximal dose-escalation of this combination regimen.
This protocol is designed to test the feasibility of the administration of vincristine, adriamycin and cytoxan, alternating with the newly developed regimen ifosfamide VP-16 as well as the efficacy of this therapy in addition to radiotherapy in producing complete responses and disease-free survival in patients with Ewing's sarcoma, primitive sarcoma of bone, peripheral neuroepithelioma, and soft tissue sarcoma. This will not be a randomized study but will be comparable to the large data base of similar patients treated on successive Pediatric Branch studies.
