Active clinical trials for "Sarcoma"

RATIONALE: Gathering information about how often metabolic syndrome occurs in young survivors of childhood cancer may help doctors learn more about the disease. PURPOSE: This clinical trial is studying metabolic syndrome in survivors of childhood cancer and in their healthy sisters and brothers.

The purpose of this study is to evaluate the impact on overall survival of an intensive follow-up protocol (as practiced today at TMH) against a more cost effective follow-up protocol in patients operated for extremity sarcoma.

The purpose of this study is to develop imaging techniques to determine the density of blood vessels and the amount of blood flow in Kaposi s sarcoma (KS) tumors. KS tumors depend on the formation of new blood vessels for their growth. Some experimental therapies for KS are directed at reducing the amount of blood vessels and blood flow in these lesions. Measurement of blood vessel density and blood flow in these lesions could be useful in evaluating the effectiveness of both standard and experimental treatments for this disease. Patients 18 years of age or older with Kaposi's sarcoma involving the skin may be eligible for this study. Participants will have photographs taken of their lesions and will undergo three imaging procedures (described below) at the beginning of the study (baseline) and then about once every 3 months or so while on the study (up to 2 years) to compare the test results over time. (Imaging may be done at more or less frequent intervals depending on the findings.) A small amount of blood (less than a tablespoon) will be drawn the day of each imaging procedure. Laser Doppler imaging This technique measures the amount of blood flow in KS lesions by scanning the lesions with a low-power laser beam. Each lesion takes about 3 minutes to scan. The imaging may be done before and after a blood pressure cuff around the arm is inflated for a short time (usually less than 30 seconds). Multi-spectral imaging This technique uses light to measure the total blood volume in each lesion and how much oxygen is in the blood. Oxygen is carried to the body s cells by a protein in red blood cells called hemoglobin. The light on the multi-spectral imaging instrument is absorbed differently depending on whether the hemoglobin has oxygen attached to it or not. It takes about 2 minutes to scan each lesion. Infrared thermal imaging This test uses a special camera to take digital infrared pictures of the skin. Images formed of the temperature of the KS lesions are used to assess blood flow in the lesions. This imaging takes about 1 minute per lesion. ...

The study is a first step of a process to establish the standard chemotherapy treatment with the aim to improve outcome for patients with these rare tumours. For this reason the study will be non-controlled clinical trial. In this regard, the study aims to determine the feasibility of intensive chemotherapy in this age group, and/or separate efficacy analyses according to the different histologic categories and whether the number of patients recruited by the co-operating groups permits future randomised studies.

RATIONALE: Studying samples of tissue 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 understand how well patients respond to treatment. PURPOSE: This research study is studying biomarkers in tissue samples from patients with Ewing sarcoma.

RATIONALE: Studying samples of blood and 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. PURPOSE: This research study is studying genes in samples from younger patients with desmoplastic small round cell tumor registered on COG-D9902 or COG-ABTR01B1.

We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.

Well-designed observational studies of individuals with rare tumors are needed to improve patient care, clinical investigations, and the education of healthcare professionals. The patterns of care, outcomes, and prognostic factors of a cohort of 2225 patients with metastatic soft tissue sarcomas who were diagnosed between 1990 and 2013 and documented in the prospectively maintained database of the French Sarcoma Group will be analyzed with a focus on : number/frequency of systemic treatments per patient, number/frequency of patients with locoregional treatment of the metastasis, number/frequency of patients with chemotherapy, number/frequency of patients with an off-label drug. Outcome (time-to-next treatment [TNT] and overall survival [OS]) will be reported according to histological subtype, as well as the association between TNT and OS. Prognostic factors of OS will be investigated.

The objectives of this trial is to evaluate efficacy and safety of treatment with Trabectedin in a large cohort of German patients with soft tissue and bone sarcomas.

Pilot, prospective, monocentric study aimed at evaluating the rate of patients with circulating "cancer cell/macrophage" hybrid cells in the peripheral blood. The study will be conducted on a population of patients with sarcoma and treated in the context of routine care. For each included patient, blood samples will be collected during baseline visit and after the initiation therapy. At the end of the 2nd blood collection, the patient will have completed his participation in the study.
