This pilot trial will examine the feasibility of administering induction high-dose therapy with antimetabolites, followed with consolidation using high-dose single alkylating agent therapy and finally intensification therapy with sequential cycles of very high doses of the natural products (paclitaxel followed by doxorubicin) to patients with metastatic breast cancer (stage IV), and to patients with lesser stage disease at high risk for relapse (patients with four or more positive nodes (stage II), locally advanced breast cancer (stage III)), and patients with locally or regionally recurrent breast cancer. Patients will receive induction therapy with antimetabolite agents (methotrexate, leucovorin and 5-fluorouracil) for four cycles. Patients will then receive consolidation therapy with three cycles of high-dose alkylating agents. First, patients will receive one cycle of high-dose cyclophosphamide administered with growth factor support. PBPCs will be harvested during the recovery phase of the cyclophosphamide cycle. The next cycle will consist of high-dose single agent thiotepa. Hematopoietic stem cells mobilized and collected during the previous cyclophosphamide cycles will be reinfused following treatment with thiotepa to augment recovery of bone marrow function. After recovery, intensification with natural product chemotherapy will be administered, consisting of four cycles of paclitaxel given as a 24-hour infusion followed by four cycles of single agent doxorubicin. This protocol combines several highly active chemotherapeutic agents in an attempt to improve upon response rates achieved with current combinations. For high-risk stage II and III patients, this chemotherapy regimen (without genetic manipulation of PBPCs) will serve as a chemotherapy backbone onto which a companion immunotherapy protocol will be offered. An identical chemotherapy regimen will be offered to stage four patients as a backbone for a trial of retroviral transduction of the MDR1 and NeoR genes into harvested PBPCs.

Cette section fournit des détails sur le plan de l'étude, y compris la manière dont l'étude est conçue et ce qu'elle évalue.
Détails du design

55 participants à inclure

Nombre total de participants que l'essai clinique vise à recruter.

Traitement

Cette étude teste un ou plusieurs traitements pour évaluer leur efficacité contre une maladie ou un problème de santé spécifique. L'objectif est de voir si un nouveau médicament ou une thérapie fonctionne mieux, ou provoque moins d'effets secondaires que les options existantes.

Critères

DISEASE CHARACTERISTICS: Histologically proven AR and ESFT which includes: Classical, atypical and extraosseous Ewing's sarcoma, primitive peripheral neuroectodermal tumors, peripheral neuroepithelioma, primitive sarcoma of bone, and ectomesenchymoma. Confirmed presence of tumor-specific infusion protein by documented RT-PCR which corresponds to one of the tumor specific peptides available for vaccination. Measurable tumor. No prior or current CNS metastases. PRIOR/CONCURRENT THERAPY: ARM A PATIENTS: May be enrolled on the protocol for the first phase in the absence of RT PCR documentation of a tumor-specific fusion protein which corresponds to one of the tumor-specific peptides available for vaccination. However, RT PCR documentation at the time of tumor recurrence must occur prior to administration of immunotherapy. At time of initial tumor diagnosis, prior to any cytoreductive therapy. ARM B PATIENTS: Tumor recurrence occurring during or after receiving at least first line cytoreductive therapy for ESFT and AR. No more than two post-recurrence salvage regimens unless peripheral CD4+T cell number is greater than 400 cells per millimeter cubed. At least 6 weeks since any treatments and recovered from all acute toxic effects from time in which immunotherapy will be started for this study. No concurrent estrogen therapy during immunotherapy section of study. PATIENT CHARACTERISTICS: Age: 2-25 (at time of initial diagnosis of alveolar rhabdomyosarcoma). Weight: Greater than 15 kg (at time of apheresis). Performance status: ECOG 0-2. Life expectancy: At least 8 weeks. Hematopoietic: ANC greater than 100,000/mm(3). Hemoglobin greater than 9.0 g/dL. Platelet count greater than 50,000/mm(3). Hepatic: Bilirubin less than 2.0 mg/dL (unless related to involvement by tumor). Transaminases less than 3 times normal (unless related to involvement by tumor). Renal: Creatinine less than 1.5 mg/dL or creatinine clearance greater than 60 mL/min. Cardiovascular: No major disorder of cardiovascular system. Cardiac ejection fraction greater than 40%. Pulmonary: No major disorder of pulmonary system. OTHER: Not pregnant or nursing. HIV negative. Hepatitis B or C negative. No patients requiring daily oral corticosteroid therapy. If allergic to eggs, egg products, or thimerosal, or have a history of Guillain-Barre syndrome, ineligible to receive influenza vaccine.
