Active clinical trials for "Sarcoma"

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 looking at tumor samples from patients with Ewing sarcoma. 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

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.

The primary objective of this research project is to estimate the number of patients with sarcoma or melanoma attending an outpatients clinic that are in pain or have unmet pain needs.

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.

To determine the seroprevalence of Kaposi's sarcoma-associated herpesvirus (KSHV/HHV8) in blood donors from Texas. Also to examine the donors' demographic characteristics and to characterize the KSHV using polymerase chain reaction.

This protocol is designed to evaluate children with cancer who appear to be probable candidates for future protocol entry or have disease manifestations that are of unique scientific importance or educational value.

The main objectives of this study are the following: to describe the prognostic factors of survival of synovial sarcoma in patients treated by the orthopedic surgery unit oncologic of the orthopedic surgery and traumatology service of the Hospital de Sant Pau during the years 1983-2016.

For bone lesions treated with chemotherapy or targeted therapy, particularly for sarcomas that originate in bones, Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 is spurious because bone lesions are typically located in irregularly shaped bones, are difficult to measure accurately, and usually respond more slowly to treatment than soft tissue lesions. Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) allows for response to be measured in the absence of anatomic changes through assessment of metabolic activity. It does not, however, account for morphologic changes. This study evaluated whether clinical imaging findings of sarcomas after preoperative chemotherapy correlate with tumor responses by pathological evaluation using the rate of necrosis to develop reliable and quantitative clinical response criteria.

Sarcomas are aggressive malignant tumors issued from mesenchymatous cells. Their curative treatment is mainly surgical, especially in soft tissue sarcomas, which are mostly localized in limbs. Surgical margins remain a major prognosis factor and are directly linked to recurrence risk. Curative surgery applies resection margins removing healthy tissue surrounding the tumor and is meticulously planned thanks to tight cooperation between expert surgeons and radiologist, based on pre-operative Magnetic resonance imaging(MRI). Resection planning optimizes chances to perform a safe carcinological resection procedure sparing these structures. Resection planning is based upon conservation (or sacrifice) of anatomic compartments limited by fascia and routine MRI might also be outdated in some cases to predict whether the fascia is involved in the tumor or not. Such uncertainties complexify the surgical procedure, lead to unnecessary healthy tissue sacrifices and increase functional impairments, which can be significant. A new MRI offering higher spatial resolution could allow tumoral satellites, previously undetected on conventional MRI, which might explain some of the observed recurrences. Ultra-high field MRI, considered as harmless and without pharmaceutical agent injection, could bring benefits to tumoral extension comprehension and should be considered as a breakthrough in medical oncology field. This is particularly true in soft tissue sarcoma pathology field, where the only curative treatment to date remains surgery. It will be propose in this project to determine the contribution of ultra-high field MRI in Soft tissue sarcomas management and to evaluate for the first time the potential superiority of 7 Tesla imaging over routine MRI through usual data comparison in 20 patients between 1,5Tesla and 7 Tesla MRI.
