Filter by:This is a perspective multicentric study for the treatment of patients aged equal or less than 60 years and submitted to an allogeneic hematopoietic stem cell transplantation from an HLA compatible related or unrelated donor because affected by resistent or refractory or relapsed after autologous stem cell transplantation Ewing Sarcoma or Soft tissues sarcoma who did not benefit from conventional therapy.
Ewing Sarcoma Primary objectives: Standard Risk R1: in a randomised trial, to examine whether add-on treatment with zoledronic acid in addition to induction and maintenance chemotherapy improves event-free survival in patients with localised Ewing sarcoma and good histological response or with initial tumour volume <200 mL compared to no add-on treatment. *High Risk R2: in a randomised trial, to examine whether high-dose chemotherapy using busulfan-melphalan with autologous stem cell reinfusion, compared with standard chemotherapy, improves event-free survival in patients with localised Ewing sarcoma and poor histological response or tumour volume ≥200 mL (R2loc). In patients with pulmonary metastases high dose busulfan-melphalan chemotherapy with autologous stem cell reinfusion is randomised versus standard chemotherapy plus whole lung irradiation (R2pulm). Very High Risk R3: in a randomised trial, to examine whether the addition of high dose chemotherapy using treosulfan-melphalan followed by autologous stem cell reinfusion to eight cycles of standard adjuvant chemotherapy, compared to eight cycles of standard adjuvant chemotherapy alone, improves event-free survival in patients with primary disseminated disease. *R2 accrual discontinued on December 1st 2015.
Patients with relapsed solid tumors such as sarcomas and neuroblastoma have a poor survival, generally < 20%. There is an urgent need for new treatments that are safe and effective. HSV1716, an oncolytic virus, is a mutant herpes simplex virus (HSV) type I, deleted in the RL1 gene which encodes the protein ICP34.5, a specific determinant of virulence. Mutants lacking the RL1 gene are capable of replication in actively dividing cells but not in terminally differentiated cells - a phenotype exploited to selectively kill tumor cells. In previous clinical studies, HSV1716 has been shown to be safe when injected at doses up to 10^5 plaque forming units (pfu) directly into human high-grade glioma and into normal brain adjacent to tumour, following excision of high-grade glioma. In an extension study, HSV1716 has been shown to be safe when injected at a dose of up to 10^6 pfu directly into brain tumours. Replication of HSV1716 in human glioblastoma in situ has been demonstrated. Following a single administration of HSV1716 by direct injection into active recurrent tumor or brain adjacent to tumor, some patients have lived longer than might have been expected. This study seeks to evaluate the safety of a single injection of HSV1716 in the treatment of extracranial solid tumors in adolescents and young adults. HSV1716 has also proved safe when given by direct intra-tumoural injection in patients with squamous carcinoma of the head and neck, and in patients with malignant melanoma. Replication of HSV mutants in human sarcomas and neuroblastoma in cultured cells and human xenograft models has been demonstrated. This study is designed in two parts. PART 1 of the study specifies a single dose of virus. Participants who experience at least stable disease or relapse following a determination of stable disease, may qualify for subsequent doses in PART 2. PART 2 requires signing of a separate consent.

Background: - Informed consent is the process by which prospective participants in clinical trials learn about clinical research in order to decide whether they want to enroll in the study. It consists of meetings and discussions with the health care team. - Phase I clinical trials are designed to determine what dose of an investigational agent is safe to administer to patients. Objectives: - To study communication, comprehension and decision-making during the informed consent process. - To examine ethical, psychological, social, and educational issues regarding informed consent. - To help researchers understand how to improve informed consent and education about clinical research. Eligibility: - Parents or guardians of children with cancer who are being considered for participation in phase I clinical trials - Prospective patients for pediatric phase I clinical trials who are between 14 and 21 years of age. - Members of the research team who obtain consent from patients and families for pediatric phase I clinical trials Design: - Research assistants observe and record the informed consent conference held with the research team and the parents and children. - After the conference, the research assistant interviews the parents in a private area about their experience during the conference and their decision-making process. They are asked about their thoughts and opinions during the informed consent conference, including the decision-making process, communication and trust in the medical team. - With their parent's permission, patients are interviewed privately to discuss their experience during the informed consent conference. - After parents and patients have made their decision about participation in the study, they are interviewed again about how they made the decision, aspects of the communication during the conference, and how they feel about the doctor. This interview is also recorded. - Parents may be contacted 6 months to 2 years from the time of their participation to be part of a parent advisory group about the informed consent process.
This research study is collecting and storing samples of tumor tissue, bone marrow, and blood from patients with Ewing sarcoma. Collecting and storing samples of tumor tissue, bone marrow, and blood from patients with cancer to test in the laboratory may help the study of cancer in the future.
This laboratory study is collecting and storing tissue, blood, and bone marrow samples from young patients with cancer. Collecting and storing samples of tissue, blood, and bone marrow from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer.

The purpose of this study is to test the usefulness of imaging with radiolabeled methionine in the evaluation of children and young adults with tumor(s). Methionine is a naturally occurring essential amino acid. It is crucial for the formation of proteins. When labeled with carbon-11 (C-11), a radioactive isotope of the naturally occurring carbon-12, the distribution of methionine can be determined noninvasively using a PET (positron emission tomography) camera. C-11 methionine (MET) has been shown valuable in the monitoring of a large number of neoplasms. Since C-11 has a short half life (20 minutes), MET must be produced in a facility very close to its intended use. Thus, it is not widely available and is produced only at select institutions with access to a cyclotron and PET chemistry facility. With the new availability of short lived tracers produced by its PET chemistry unit, St. Jude Children's Research Hospital (St. Jude) is one of only a few facilities with the capabilities and interests to evaluate the utility of PET scanning in the detection of tumors, evaluation of response to therapy, and distinction of residual tumor from scar tissue in patients who have completed therapy. The investigators propose to examine the biodistribution of MET in patients with malignant solid neoplasms, with emphasis on central nervous system (CNS) tumors and sarcomas. This project introduces a new diagnostic test for the noninvasive evaluation of neoplasms in pediatric oncology. Although not the primary purpose of this proposal, the investigators anticipate that MET studies will provide useful clinical information for the management of patients with malignant neoplasms.
This phase II trial is studying the side effects and how well cixutumumab works in treating patients with relapsed or refractory solid tumors. Monoclonal antibodies, such as cixutumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.
The purpose of the study is to assess the functional outcome, quality of life and late sequelae in a representative sample of 600 long-term survivors of Ewing sarcoma and to build a unique clinical and functional data pool of the underlying cohort of 3000 Ewing sarcoma patients with a follow-up of 3 decades.
