Etiosarc: Environmental Aetiology of Sarcomas From a Multicenter French Population-based Case-control Study Among Adults

Introduction: Sarcomas are rare tumors of connective tissue. The exact overall incidence of sarcomas is unknown due to diagnostic difficulties and the various histological subtypes (over 80 subtypes). However, the apparent increasing incidence of sarcomas suggests environmental causes such as pesticides. Except for some specific factors (i.e. ionizing radiation, vinyl chloride, dioxin, and genetic predispositions) the scientific knowledge on the aetiology of sarcomas is sparse and inconsistent. France is a particularly appropriate country to set up a study investigating the causes of sarcoma occurrence due to the French organization in treatment and care of sarcoma patients, which is highly structured and revolved around national expert networks. The main objective of the ETIOSARC project is to study the role of lifestyle, environmental and occupational factors in the occurrence of sarcomas among adults from a multicentric population-based case-control study. Methods and analysis: Cases will be all incident cases (older than 18 years old) identified in 15 districts of France covered by a cancer registry and/or a reference center in sarcoma's patient care over a three-year period with an inclusion start date ranging from the 1st October 2018 to the 1st January 2020 and histologically confirmed by a second review of the diagnosis. Two controls will be individually-matched by sex, age (5-years group), and districts of residence and randomly selected from electoral list. A standardized questionnaire will be administered by a trained interviewer in order to gather information about occupational and residential history, demographic and socioeconomic characteristics and lifestyle factors. At the end of the interview, a saliva sample will be systematically proposed. This study will permit to validate or not already suspected risk factors for sarcomas such as phenoxyherbicides, chlorophenol and to generate new hypothesis to increase our understanding about the genetic and environmental contributions in the carcinogenicity process.

HER2 Chimeric Antigen Receptor (CAR) T Cells in Combination With Checkpoint Blockade in Patients With Advanced Sarcoma

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.

Feasibility and Preliminary Efficacy of a Mindfulness-based Intervention for Children and Young Adults With High Grade or High-Risk Cancer and Their Caregivers

Background: People cope with cancer in different ways. Mindfulness means focusing on the present moment with an open mind. Researchers want to see if this can help children and young adults with a high-grade high-risk cancer with poor prognosis. Objective: To learn if mindfulness is feasible and acceptable for children and young people with high-grade high-risk cancer with poor prognosis and their caregivers. Eligibility: Children ages 5 24 with a high-grade or high-risk cancer, with a caregiver who agrees to do the study Must have internet access (participants may borrow an iPod for the study) Must speak English Design: All participants will complete questionnaires. These will be about feelings, physical well-being, quality of life, and mindfulness. Researchers will review children s medical records. Participants will be randomly put in the mindfulness group or the standard care group. Participants in the standard care group will: Get general recommendations for coping with cancer Have check-in sessions 1 and 3 weeks after starting. These will last about 10 minutes each. After participants finish the standard care group, they may be able to enroll in the mindfulness group. Participants in the mindfulness group will: Attend an in-person mindfulness training session. The child participant will meet with one research team member for 90 minutes while the parent participant meets with another. Then they will come together for a half hour. Practice mindfulness exercises at least 4 days a week for 8 weeks. Be asked to respond to weekly emails or texts asking about their mindfulness practice Get a mindfulness kit with things to help them do their mindfulness activities at home. Have a 30-minute check-in with their coach 1 and 3 weeks after starting. This can be in person or by video chat. All participants (from both groups) will be asked to answer follow-up questions about 8 and 16 weeks after starting the study. Participants will be paid $20 for each set of questionnaires they complete to thank them for their time. ...

PLX3397 in Children and Young Adults With Refractory Leukemias and Refractory Solid Tumors Including Neurofibromatosis Type 1 (NF1) Associated Plexiform Neurofibromas (PN)

Background: - Some people with cancer have solid tumors. Others have refractory leukemia. This doesn t go away after treatment. Researchers want to see if a drug called PLX3397 can shrink tumors or stop them from growing. Objectives: - To find the highest safe dose and side effects of PLX3397. To see if it helps treat certain types of cancer. Eligibility: People ages 3 22 with a solid tumor or leukemia that has returned or not responded to cancer therapies. For Phase II, people ages 3 31 with a Neurofibromatosis Type 1 (NF1) Associated Plexiform Neurofibroma (PN) that cannot be removed with surgery. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Heart tests Scans or other tests of the tumor Participants will take PLX3397 as a capsule once daily for a 28-day cycle. They can do this for up to 2 years. During the study, participants will have many tests and procedures. They include repeats of the screening tests. Participants will keep a diary of symptoms. Participants with solid tumors will have scans or x-rays. Participants with NF1 PN will have MRI scans. Participants with leukemia will have blood tests. They may have a bone marrow sample taken. Some participants may have a biopsy. When finished taking PLX3397, participants will have follow-up visits. They will repeat the screening tests and note side effects. Phase II will follow the same procedures as Phase I above, but participants will also fill out questionnaires about their pain and quality of life.
