Clinical Trials [3049 Associated Clinical Trials listed on BioPortfolio]

IMC-A12 in Treating Young Patients With Relapsed or Refractory Ewing Sarcoma/Peripheral Primitive Neuroectodermal Tumor or Other Solid Tumor

RATIONALE: Monoclonal antibodies, such as IMC-A12, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help k...

Exatecan Mesylate in Treating Patients With Ewing's Sarcoma, Primitive Neuroectodermal Tumor, or Desmoplastic Small Round Cell Tumor

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of exatecan mesy...

A Pilot Study for the Treatment of Patients With Metastatic and High Risk Sarcomas and Primitive Neuroectodermal Tumors

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...

Studying DNA in Tumor Tissue Samples From Patients With Localized or Metastatic Osteosarcoma

RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers relate...

18F-FLT Positron Emission Tomography and Diffusion-Weighted Magnetic Resonance Imaging in Planning Surgery and Radiation Therapy and Measuring Response in Patients With Newly Diagnosed Ewing Sarcoma

This pilot trial studies fluorine F 18 fluorothymidine (18F-FLT) positron emission tomography and diffusion-weighted magnetic resonance imaging in planing surgery and radiation therapy and...

Clinical features and long-term outcome of primary intracranial Ewing sarcoma/peripheral primitive neuroectodermal tumors: 14 cases from a single institution.

Primary intracranial Ewing sarcoma (ES)/peripheral primitive neuroectodermal tumors (pPNETs) are extremely rare, and only a few studies have reported more than four cases of this disease. The purpose ...

Risk stratification by somatic mutation burden in Ewing sarcoma.

Up to one-third of patients with localized Ewing sarcoma (ES) develop recurrent disease, but current biomarkers do not accurately identify this high-risk group. Therefore, the objective of this study ...

An elderly lady with intracranial peripheral primitive neuroectodermal tumor arising from the clivus with intracranial metastasis: A case report with review of literature.

Intracranial Peripheral Primitive Neuroectodermal Tumor(pPNET) are rare lesions, accounting for only 1% of all pPNET and usually arise from bone and soft tissue. These are tumours primarily affecting ...

Timing of Local Therapy Impacts Survival in Ewing Sarcoma.

We aimed to investigate the relationship between survival and time to local therapy following initiation of upfront chemotherapy in the treatment of localized Ewing sarcoma patients.

Long-term outcomes of surgical resection with or without adjuvant therapy for treatment of primary spinal peripheral primitive neuroectodermal tumors.

We sought to assess the use of surgical treatment, the effect of postoperative adjuvant therapy, and the prognostic factors for survival of patients with primary spinal peripheral primitive neuroectod...

Medical and Biotech [MESH] Definitions

A group of highly cellular primitive round cell neoplasms which occur extracranially in soft tissue and bone and are derived from embryonal neural crest cells. These tumors occur primarily in children and adolescents and share a number of characteristics with Ewing's Sarcoma (SARCOMA, EWING'S). They may arise from the chest wall, skin, orbit, kidney, and other structures and tend to be locally invasive or metastasize, although relatively benign forms may occur. Characteristic histologic features include a tendency to form Homer-Wright rosettes and to stain positively with neuron-specific enolase and vimentin. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2113; J Clin Oncol 1998 Mar;16(3):1150-7)

A ubiquitous hnRNP protein found in the CELL NUCLEUS and the CYTOPLASM. Translocations that result in the formation of fusion proteins containing parts of RNA-binding protein EWS may play a role in neoplastic processes such as Ewing Sarcoma (SARCOMA, EWING'S).

A trans-activator and member of the erythroblast transformation-specific family of transcriptions factors that contain a characteristic ETS MOTIF. It is required for PLATELET CELL ADHESION to the subendothelium and associates with CHIMERIC ONCOGENE PROTEINS in PROSTATE CANCER; EWING'S SARCOMA; and ACUTE MYELOID LEUKEMIA.

A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2059)

Body of knowledge related to the use of organisms, cells or cell-derived constituents for the purpose of developing products which are technically, scientifically and clinically useful. Alteration of biologic function at the molecular level (i.e., GENETIC ENGINEERING) is a central focus; laboratory methods used include TRANSFECTION and CLONING technologies, sequence and structure analysis algorithms, computer databases, and gene and protein structure function analysis and prediction.
