Active clinical trials for "Osteosarcoma"

This study will enroll patients who have a diagnosis of locally advanced, unresectable or metastatic soft tissue or bone sarcoma (except gastrointestinal stromal tumors and Kaposi's sarcoma) from any site.

To find a recommended dose of donated NK cells that can be given with lymphodepleting chemotherapy to patients with advanced renal cell carcinoma, mesothelioma, or osteosarcoma. The effects of this therapy will also be studied.

Thanks to the intrinsic qualities of the proton beam, proton therapy will reduce adverse effects of irradiation. The Proteus®One is the latest generation of proton therapy equipment, enabling the Centre Antoine Lacassagne to expand its range of treatments by carrying out new proton therapy treatments. It has an innovative compact isocentric rotating head (Gantry) that allows the radiation beam to be directed at different angles around the patient. In some cases, two beams are used to treat tumours, and by convention, both beams are delivered during the same session. However, it is necessary to position the patient before each beam, which is time-consuming because 2 beams have to be positioned very precisely each day. The aim of this study is therefore to assess the toxicity of proton therapy delivered by a single daily beam compared with proton therapy delivered by two daily beams, which is the conventional technique.

To find a recommended dose of attIL2-T cell therapy that can be given to patients with soft tissue or bone sarcomas and to see if it can help to control the disease.

This is a single-arm, phase II study that will enroll a total of 45 subjects. All subjects will have a confirmed diagnosis of metastatic or unresectable soft tissue sarcoma or bone sarcoma. All subjects must have intact Rb, identified at the time of screening, by immunohistochemistry testing of submitted tumor specimen. Subjects will receive Abemaciclib 200 mg twice daily until progression or discontinuation criteria are met.

In this study, the investigators aim to reduce complications in orthopedic malignancy surgeries and to increase the quality of life of patients who will be operated on.

investigator will see the efficacy of tranexamic acid in limb salvage surgery patients which will prevent blood loss and help in conservation of blood products.

This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.

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 is a prospective study that will conduct a series of focus groups with non-Hispanic Black and Hispanic childhood cancer survivors to obtain their input on culturally adapting a mobile CBT program for chronic pain and tDCS procedures. Once this adaptation process is completed, the investigators will conduct a feasibility trial with non-Hispanic Black, Hispanic and non-Hispanic White childhood cancer survivors of bone sarcoma with chronic pain. The feasibility study will assign eligible participants to either culturally adapted mobile CBT + active tDCS to the dorsolateral prefrontal cortex or culturally adapted mobile CBT + sham tDCS. We anticipate approximately 60 participants for the focus groups and approximately 30 participants for the feasibility study for a total of about 90 participants.
