Active clinical trials for "Osteosarcoma"

The aim of the study is to assess the accuracy of dynamic contrast enhanced and diffusion-weighted MR Imaging in evaluating response to chemotherapy in osteosarcoma.

This clinical trial studies genetic biomarkers in tissue samples from patients with osteosarcoma. Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer

After Institutional Review Board approval, adult patients scheduled for total knee arthroplasty (TKA) will be enrolled into the study after obtaining informed consent over a 24 month period. Interim analyses of cases who have completed the 6 month follow up as on 31st October, 2017 will be analyzed as part of the co- principle investigator's thesis. All consenting patients will be assessed for pain preoperatively, the first 3 post-operative days, at 1, 4 and 6 months from the date of surgery. Pain scores will be assessed using the Numerical Rating Scale during the 3 postoperative days. Pain will be managed by the Acute Pain Service team as per standard protocols. The Brief pain inventory (BPI) (short form with translations, obtained with permission from MD Anderson), which assesses pain severity and its impact on daily functions will be administered to the patient in a language familiar to them, preoperatively, at 1, 4 and 6 months postoperatively. The Musculoskeletal Tumour Society Score (MSTS) which evaluates the functional condition (impairment) after completed tumour treatment will be estimated at the end of 6 months from the date of surgery The painDETECT questionnaire (PD-Q) a quick, simple and reliable screening tool to identify the likelihood of a neuropathic pain component in patients and validated in various languages including Hindi and Marathi will be administered preoperatively and at 1, 4 and 6 months after surgery. Details of postoperative chemotherapy and radiation will also be obtained from patient's notes and the electronic medical record. If the patient cannot follow up at the said intervals, the pain scores would be obtained telephonically and the BPI and PD-Q forms in prepaid envelopes would be given to them at discharge which they would have to duly fill in and post them to the given address at the appropriate intervals if they cannot visit the pain clinic. At the 6th month of follow up, they would be requested to visit the pain clinic for an assessment of MSTS score and completing the BPI and PD-Q. INCLUSION CRITERIA:- Adult patients above 18 years of age, undergoing TKR Literate: able to read and write in at least one of the following languages English, Hindi and Marathi Willing to fill forms and post them and/or answer questions on phone EXCLUSION CRITERIA:- Refusal of consent Cognitively impaired Revision TKRs (including cases with wound wash and nail spacer cementing)

The purpose of this study is to collect and store samples of blood and tumor tissue from patients with osteosarcoma. Collecting and storing samples of tumor tissue and blood from patients to test in the laboratory may help the study of cancer in the future.

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.

To establish a serial ascertainement of specimens from patients with bone sarcomas to be used in ongoing cytogenetic and molecular genetic analyses. These data will be integrated and correlated with the established Orthopaedic Service clinical database.

The purpose of this work is to carry out an exhaustive analysis of the characteristics of osteosarcoma in patients with an age equal to or greater than 40 years, in the Hospital de la Santa Creu and Sant Pau in Barcelona, during the years 1986-2016, with the objective to establish the factors that determine the disease and survival, as well as to evaluate the rates of limb salvage and amputation after neodyuvant chemotherapy. With the result of the results, the report of osteosarcoma and the age less than 40 years, with the aim of providing new information that is related to the appearance of osteosarcoma is available from 40 years.

This research study is studying biomarkers in predicting response to chemotherapy in samples from young patients with osteosarcoma. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.

using a contrast-enhanced (CE) cardiac magnetic resonance imaging(CMR) which included the measurement of T1 mapping, T2 mapping, T2* mapping and late gadolinium enhancement(LGE) sequences, as well as LVEF and extracellular volume(ECV) to evaluate the respective changes before and after anthracycline chemotherapy.
