Active clinical trials for "Sarcoma, Synovial"

Patients with a diagnosis listed under "conditions" below are eligible to be considered for the EAP. These conditions must be serious or life-threatening at the time of enrollment and appropriate, comparable, or satisfactory alternative treatments must have been tried without clinical success. Patients with conditions not listed under "conditions" below are not eligible for the tazemetostat EAP.

The sarcomas represent 1% of all cancers in adults, 8% in adolescents and young people, and 10% in children. Even though it is a rare cancer, it contributes to a significant loss of years of life in comparison with other types of cancer, due the fact that it affects children and young people. The diagnosis and treatment are difficult, considering the diversity and rarity of this disease. In addition, on average, more than 50% of patients with high-grade sarcoma present tumor relapse and distant recurrence is considered the main cause of death. The presence of Circulating Tumor Cells (CTCs) in the blood of patients with sarcoma may be an early marker of tumor invasion, because it is known that the CTCs circulate in the blood for months or years before the development of metastases. The CTCs can be used to monitor the response of the tumor to treatment, in order to match time, dose, and type of therapy. Objectives: collect blood from patients with different types of sarcoma (leiomyosarcoma, synovial sarcoma, pleomorphic sarcoma and liposarcoma) in order to isolate and quantify CTCs. The investigators also have an intention to identify genes of resistance to treatment in these cells.
