Active clinical trials for "Osteosarcoma"

Hu14.18K322A is a monoclonal antibody developed at St. Jude Children's Research Hospital (SJCRH) that is made to bind to cancer cells that have a molecule called GD2 on their surface. Sometimes the human body will make an antibody to the therapeutic antibody (like hu14.18K322A) that is being given for treatment. These are called human anti-human antibodies (HAHA). When testing for HAHA in a previous cohort of patients who received hu14.18K322A, it was found that some patients tested positive for high levels of an antibody before receiving hu14.18K322A or any other anti-GD2 antibody. In this study, investigators would like to know more about the nature of this pretreatment antibody, how often is it present, and if in the laboratory it increases the killing of tumor cells. OBJECTIVES: To determine whether pretreatment anti-therapeutic antibodies (PATA) represent antibodies reactive against an epitope (allotypic determinant) found on the anti-GD2 antibody hu14.18K322A To determine if PATA increases the anti-tumor efficacy of anti-GD2 antibodies in vitro

This application proposes a prospective clinical trial to evaluate the impact of adding a focused physical therapy (PT) intervention to the preoperative regimen of individuals diagnosed with a malignancy of the lower extremity (LE). The primary aim will be to determine if individuals diagnosed with a malignancy of the LE can participate in a 10 week preoperative strengthening, stretching, and aerobic exercise regimen.

This trial studies biomarker expression in tissue samples from patients with bone sarcomas. Studying biomarker in tissue samples from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer

The aim of the proposed project is to study the long-term impact of adjuvant systemic multi- agent chemotherapy (cisplatin, anthracyclines, vincristine, methotrexate, alkylating agents) in survivors (treated between 1992 and 2014 in UZ Leuven) of paediatric bone or soft tissue sarcomas on neurocognitive functioning.

This study is a prospective, non-randomized observational study. Freshly isolated tumor cells will be tested for chemosensitivity to the standard of care drugs as single agents and in combinations using state-of-the-art viability assay designed for ex-vivo high-throughput drug sensitivity testing (DST). In addition, the genetic profile of the tumor will be obtained from the medical records and correlated with drug response.

Post-authorization, observational, multicenter and prospective study in patients between 2 and 30 years old diagnosed with non-metastatic high-grade osteosarcoma of the extremities. All patients included in the study will receive the initial neoadjuvant treatment prescribed by the doctor of each center, according to standard practice (involving methotrexate, cisplatin, and adriamycin). This initial treatment precedes surgical treatment. After surgical treatment, the histological response to neoadjuvant chemotherapy will be evaluated. The histological response to primary chemotherapy will be expressed as a percentage of tumor necrosis. In the case of tumor necrosis above 90% the patient is defined as a "good responder" in case of a lower percentage as a "poor responder". As an adjuvant treatment, the following options may be given according to standard practice in each center: - If there is overexpression of ABCB1 / P-glycoprotein and poor response to induction treatment, in many sites ifosfamide at high doses and MTP-PE, is incorporated in addition to adriamycin. - If there is overexpression of ABCB1 / P-glycoprotein and a good response to induction treatment, in many centers the option of additional administration of methotrexate, CDDP and adriamycin will be chosen. - If there is no overexpression of ABCB1 / P-glycoprotein, the administration of methotrexate, adriamycin and cisplatin will be chosen in many sites. In some sites they will consider the non-administration of MTP-PE or the non-administration of high doses of ifosfamide. And, in some hospitals, they will consider administering MTP-PE to all patients.

This research trial studies blood samples from patients with osteosarcoma. Studying the genes found in samples of blood from patients with osteosarcoma may help doctors identify biomarkers related to the disease.

Patients who are being considered for participation in a NCI Pediatric Oncology Branch research study will be screened for eligibility under this protocol. For every NCI research study, patients must meet defined medical criteria in order to ensure the integrity of the research study and to maximize patient safety. Tests and procedures required for determining eligibility depend on the specific study for which the patient is being considered. Some of the more common tests and procedures are: History and physical examination Blood and urine samples for routine laboratory tests and possibly research studies Quality of life assessment questionnaire Magnetic resonance imaging (MRI) scan uses a magnetic field and radio waves to produce pictures of body structures, including tumors Computerized tomography (CT) scan uses radiation to produce multiple detailed pictures of body structures X-rays uses radiation to provide a single picture of a body part Nuclear medicine scans uses a chemical tagged with a radioactive substance to detect tumors, measure kidney or heart function, or monitor the flow of cerebrospinal fluid (fluid that bathes the brain and spinal cord) Electrocardiogram (EKG) uses electrodes placed on the skin to evaluates heart rate and rhythm by measuring electrical impulses from the heart Echocardiogram uses high-frequency sound waves to evaluate heart structure and function Lumbar puncture tests for cancer cells and other substances in cerebrospinal fluid. Involves placing a needle into the lower back between the bones of the spine and withdrawing a fluid sample from the fluid-containing space below the spinal cord Ommaya reservoir surgically implanted catheter inserted into the fluid-filled ventricles of the brain, used to withdraw spinal fluid samples and to give medication Eye examination vision test and eye examination Biopsies removal of a small piece of tissue, by needle or by surgery, for examination under the microscope. An area of skin over the biopsy site is numbed with an anesthetic. For a needle biopsy, a needle is inserted into the tumor, tissue or bone marrow to pull out a small sample. A surgical biopsy may be done in the operating room, clinic, or hospital room, depending on the biopsy location. The tissue or tumor is removed by cutting a small piece of it with a sharp knife or scalpel and the area will be closed with sutures or staples.

The goal of this type of observational study is to investigate the preliminary effect of 3D printed personalized extendable prosthesis replacement on limb salvage in children with osteosarcoma. The main question it aims to answer is: Is 3D printed personalized extendable prosthesis replacement has a good outcome in limb salvage pediatric osteosarcoma？
