This study compares carbon ion therapy, surgery, and proton therapy to determine if one has better disease control and fewer side effects. There are three types of radiation treatment used for pelvic bone sarcomas: surgery with or without photon/proton therapy, proton therapy alone, and carbon ion therapy alone. The purpose of this study is to compare quality of life among patients treated for pelvic bone sarcomas across the world, and to determine if carbon ion therapy improves quality of life compared to surgery and disease control compared with proton therapy.
The purpose of this study is to learn whether it is safe to give HER2-CAR T cells in combination with an immune checkpoint inhibitor drug (pembrolizumab or nivolumab), to learn what the side effects are, and to see whether this therapy might help patients with sarcoma. Another goal of this study is to study the bacteria found in the stool of patients with sarcoma who are being treated with HER2 CAR T cells and immune checkpoint inhibitor drugs to see if the types of bacteria influence how well the treatment works. The investigators have found from previous research that they can put a new gene into T cells that will make them recognize cancer cells and kill them. They now want to see if they can put a new gene in these cells that will let the T cells recognize and kill sarcoma cells. The new gene that the investigators will put in makes an antibody specific for HER2 (Human Epidermal Growth Factor Receptor 2) that binds to sarcoma cells. In addition, it contains CD28, which stimulated T cells and make them last longer. After this new gene is put into the T cell, the T cell becomes known as a chimeric antigen receptor T cell or CAR T cell. In another clinical study using these CAR T cells targeting HER2 as well as other studies using CAR T cells, investigators found that giving chemotherapy before the T cell infusion can improve the effect the T cells can have. Giving chemotherapy before a T cell infusion is called lymphodepletion since the chemotherapy is specifically chosen to decrease the number of lymphocytes in the body. Decreasing the number of the patient's lymphocytes first should allow the infused T cells to expand in the body, and potentially kill cancer cells more effectively. The chemotherapy used for lymphodepletion is a combination of cyclophosphamide and fludarabine. After the patient receives the lymphodepletion chemotherapy and CAR T cells during treatment on the study, they will receive an antibody drug called an immune checkpoint inhibitor, pembrolizumab or nivolumab. Immune checkpoint inhibitors are drugs that remove the brakes on the immune system to allow it to act against cancer.
3CAR is being done to investigate an immunotherapy for patients with solid tumors. It is a Phase I clinical trial evaluating the use of autologous T cells genetically engineered to express B7-H3-CARs for patients ≤ 21 years old, with relapsed/refractory B7-H3+ solid tumors. This study will evaluate the safety and maximum tolerated dose of B7-H3-CAR T cells.The purpose of this study is to find the maximum (highest) dose of B7-H3-CAR T cells that are safe to give to patients with B7-H3-positive solid tumors. Primary objective To determine the safety of one intravenous infusion of autologous, B7-H3-CAR T cells in patients (≤ 21 years) with recurrent/refractory B7-H3+ solid tumors after lymphodepleting chemotherapy Secondary objective To evaluate the antitumor activity of B7-H3-CAR T cells Exploratory objectives - To evaluate the tumor environment after treatment with B7-H3-CAR T cells - To assess the immunophenotype, clonal structure and endogenous repertoire of B7-H3-CAR T cells and unmodified T cells - To characterize the cytokine profile in the peripheral blood after treatment with B7-H3-CAR T cells
This phase I/II trial evaluates the highest safe dose, side effects, and possible benefits of tegavivint in treating patients with solid tumors that has come back (recurrent) or does not respond to treatment (refractory). Tegavivint interferes with the binding of beta-catenin to TBL1, which may help stop the growth of tumor cells by blocking the signals passed from one molecule to another inside a cell that tell a cell to grow.
Observational prospective trial aimed to collect the collect demographic, clinical, surgical, pathological and molecular characteristics and treatment from patients affected by skeletal Ewing Sarcoma
This is a pilot study of LTLD with MR-HIFU hyperthermia followed by ablation in subjects with refractory/relapsed solid tumors.
Primitive bone sarcoma are rare tumors with low options of therapy for patient treatment. 1. 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% . 2. 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.
Osteosarcoma and Ewing sarcoma treatment has not changed in the last 30 years. For other types of cancer the epidemiologic and prognostic correlations between dietary behavior, lifestyle and metabolic alterations (i.e.obesity, insulin-resistance) are well known (breast cancer, prostate cancer, colon cancer). However, no epidemiological or prognostic data are available about the metabolic profile and lifestyle behaviors in patients with osteosarcoma and Ewing'sarcoma and only few preclinical studies are available. An in vitro study showed a higher glucose and glutamine consumption from metastatic osteosarcoma cells compared to primary tumor osteosarcoma cells. The effect of the intestinal microbiota into the metabolism of nutrients, drugs, inflammation, epigenetic and immune response was found not only correlated to gastrointestinal tumors but also to other tumors outside gastrointestinal system as well The aim of this study is to investigate if there are differential dietary habits, metabolome, microbiota or immune profile in patients with bone sarcoma compared to a control population in a 1:2 multicenter study.
INTRODUCTION: Approximately 44% of cancer survivors experience a deteriorated quality of life 5 years after diagnosis due to late onset of complications related to cancer treatments. The objective of the study is to evaluate the incidence rates of treatment-related complications, identify sub-clinical abnormalities and risk factors in patients participating in the PASCA post-treatment program. METHOD: PASCA is a single-center, interventional cohort study of adult patients who received at least chemotherapy and with a complete remission to a testicular germ cell tumor, primary non-metastatic invasive breast carcinoma, high-grade soft tissue sarcoma, osteosarcoma, Ewing's sarcoma, acute myeloid leukemia, Hodgkin's or aggressive non-Hodgkin's lymphoma. Four assessment visits will be scheduled at 1 month (T1), 6 months (T2), 24 months (T3) and 60 months (T4) after completion of treatment. During these visits, 22 complications will be screened and follow-up care will be systematically offered to the health professional concerned by the complication in case of a positive result. The screening will contain the following elements: screening self-questionnaires, quality of life questionnaire, 12 biological parameters, a urinalysis evaluating hematuria, proteinuria, and leukocyturia, a spirometry, an electrocardiogram, 5 tests evaluating physical condition, vital signs and the perimetric measurement between both arms. DISCUSSION: This systematic screening could highlight a number of complications occurring after cancer treatments. Sub-clinical abnormalities and new risk factors could also be identified. This new organization of care could improve the quality of life of adult cancer survivors.
