Active clinical trials for "Sarcoma"

This pilot study aims to investigate the PSMA expression in the biopsy material of advanced soft tissue sarcomas and advanced urothelial cell carcinomas, and in case of high PSMA expression (as defined by previous literature), to investigate whether this correlates with high tracer uptake on PSMA-targeted PET. This way, (a subset of) patients can be selected that could benefit from radionuclide targeted therapy in the future.

This rollover protocol allows continued access to seclidemstat (SP-2577) for patients who are still receiving clinical benefit on completed or closed Salarius sponsored studies.

The goal of this clinical trial is to explore the potential survival benefits of neoadjuvant chemotherapy combined with target treatments followed by radical surgery in patients with primary high-risk/grade retroperitoneal sarcoma. The main questions it aims to answer are: Whether the 1,3-year progression-free survival time(PFS) is prolonged in the neoadjuvant therapy group, compared with the surgery-only group. The Overall survival time in the two groups. The safety and tolerance in the neoadjuvant therapy group. Participants will be allocated into two groups once they meet the inclusion criteria. Surgery-only Group: Patients will directly undergo surgeries after the confirmation of diagnosis through pre-operative biopsy. Neoadjuvant therapy group: Patients will receive the neoadjuvant chemotherapy combined with target treatment for three circles before the following sarcoma resectional surgeries.

A prospective, open-label, phase 2 study to explore CAIX expression through 89Zirconium-labelled girentuximab deferoxamine (89Zr-girentuximab) PET/CT imaging in patients with solid tumors.

This is a biology driven, monocentric study, designed to identify biomarkers of activity of trabectedin in patients with advanced non-L soft-tissue sarcoma. The aim of this study is to implement high-throughput profiling technologies to identify predictive biomarkers of trabectedin efficacy through sequential tumor biopsies and blood sample collection in sarcoma patients.

This is a study comparing two methods of dressing a post operative wound that are currently in practice. One method is a traditional dry gauze dressing. The other method is using a negative pressure dressing that provides gentle suction on the wound. The investigators will attempt to determine how well the use of post-operative negative pressure dressing reduces wound healing problems in patients who have surgery after radiation for a sarcoma in the thigh or leg.

Tumor margin confirmation is important to confirming appropriate disease excision. Current standard of care is to take select margin samples to pathology for intra-operative readings. However, this is expensive, time consuming, and only assesses the margin contained within the specific sample. In prior work the investigators have determined that indocyanine green (ICG) is highly specific to the tumor bed when injected shortly before surgery. The investigators hypothesize that ICG will be able to accurately identify residual positive tumor margins during sarcoma excision procedures.

Primitive bone sarcoma are rare tumors with low options of therapy for patient treatment. OSTEOSARCOMA VERY POOR RESPONDER COHORT. Necrosis on primitive localized osteosarcoma represents one of the principal prognostic factors. Nowadays, for localized osteosarcoma there is no maintenance therapy that have shown to be effective. In ISG-OS1 study in patients with necrosis < 60% had an event free survival (EFS) at 3 yrs of 20% (Ferrari S ) in a more recent analysis (Tsuda Y 2020) patients with a necrosis <60% had a 3 y EFS of 35% . OSTEOSARCOMA AND EWING'S SARCOMA AFTER FIRST RELAPSE Maintenance therapy after Complete Remission occurring after Ewing's sarcoma or osteosarcoma patients is not a standard rule. These patients when free from disease, after first relapse, are more likely to face a second relapse. EFS at ONE YEAR after first relapse in osteosarcoma is shown in literature to be around 21% (Leary SE 2013) and 16% (Tirtei E 2017). The EFS at ONE YEAR after first relapse in Ewing's sarcoma is inferior to 20% (Barker 2005, Ferrari S 2015). A maintenance therapy with low toxicity in these high risk patients could be an option. Metformin has been reported to a reduce the incidence of different type of cancer in diabetic patients. Metformin is well tolerated in diabetics an it is used in other conditions in non diabetic, as ovarian polycystic syndrome, metabolic syndrome and obesity. Metformin has been employed as chemoprevention related to its mechanism of action in breast cancer (NCT01101438 ) and in pediatric cancer together with chemotherapy (NCT01528046). This study aim to explore the effectiveness of metformin (a low cost and well tolerated drug) as maintenance therapy in osteosarcoma and Ewing sarcoma patients at high risk of relapse.

This clinical trial evaluates whether patients with deep soft tissue sarcomas who receive a tailored prehabilitation exercise regimen during standard radiotherapy and prior to standard of care surgery have better recovery and surgical outcomes than those who do not. Patients undergoing surgery to soft tissue sarcomas are at high risk for post-operative disability, which is associated with high rates of depression and poor health-related quality of life. Prehabilitation is the practice of exercising before surgery to ensure that the patient is in the best possible condition. It allows patients to prepare their bodies for recovery after surgery, which may result in better surgical outcomes, recovery, and quality of life after surgery.

This is a randomized (1:1 ratio), prospective, comparative, controlled, open-label study. The aim is to compare the efficacy of negative pressure therapy (PREVENA™) versus standard postoperative wound management on the wound healing after surgery for previously irradiated Soft Tissue Sarcoma (STS)
