Filter by: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 trial will be a pilot study to find out if zoledronic acid improves the response to chemotherapy in high grade osteosarcoma. In arm A of the study, 40 adult patients will be randomised into two groups. One group will get standard chemotherapy and the other group will get Zoledronic acid in addition to chemotherapy. The investigators will assess the histological necrosis as well as disease status for up to 2 years. In Arm B, adult patients with relapsed disease or advanced disease who are unable to take any other therapy and are given only symptomatic care will be given 6 doses of zoledronic acid and followed up for disease status. This will be to determine the role of zoledronic acid as a single agent.
Curcumin as well as the ashwagandha extract are ingredients from traditional indian medicine and have been shown to be potent anti-cancer compounds in laboratory as well as animal studies. This study will test the safety and efficacy of a curcumin formulation and the ashwagandha extract in high grade relapsed or metastatic osteosarcoma where no other second line chemotherapy is being given. The pharmacokinetics will be studied along with response as measured on CT scans and PET scans as well as the quality of life and any toxicity.
Data involving orthopaedic conditions and rehabilitation aspects of musculoskeletal and neuromuscular disorders will be collected and stored as part of the normal clinical care of patients seen in the University of Florida (UF) and Shands Orthopaedics and Sports Medicine Institute.
This is a phase II study to determine the antitumor activity of Vinorelbine and Cyclofosfamide association among patients with refractory tumours or in relapse with rhabdomyosarcomas and other soft tissue tumours, Ewing tumours, osteosarcomas, neuroblastomas or medulloblastomas.
