Filter by:Background: Cancers of the nasal cavity or skull base are rare. They often are not diagnosed until they are at an advanced stage, and they often spread to other parts of the body. These cancers may have mutations in a gene called IDH2. Researchers want to find out if a drug (enasidenib) that targets the IDH2 mutation can help people with these cancers. Objective: To test enasidenib in people with cancers of the nasal cavity or skull base. Eligibility: People aged 18 years and older with rare cancers of the nasal cavity or the base of the skull. Their cancer must have an IDH2 gene mutation, and it must have recurred locally or spread to other parts of the body. These cancers can include sinonasal undifferentiated carcinoma; olfactory neuroblastoma; sinonasal large-cell neuroendocrine carcinoma; poorly differentiated sinonasal adenocarcinoma; or chondrosarcoma. Design: Participants will be screened. They will have a physical exam with blood and urine tests and tests of their heart function. They will have imaging scans of their brain, skull base, neck, chest, abdomen, and pelvis. A sample of tumor tissue will be collected. Enasidenib is a tablet taken by mouth with a glass of water. Participants will take the drug once a day, every day, in 28-day cycles. They will not have resting periods between cycles. Participants will visit the clinic on the first day of each cycle to receive the tablets they will need to take at home until the beginning of the next cycle. They will keep a diary to record the time of each dose they take. Participants may remain in the study as long as the drug is helping them....
Study CL3-95031-007 (CHONQUER) is a Phase 3, international, multicenter, double-blind, randomized, placebo-controlled study of orally administered ivosidenib. Participants are required to have a histopathological diagnosis consistent with isocitrate dehydrogenase-1 (IDH1) gene-mutated, locally advanced or metastatic conventional chondrosarcoma Grades 1, 2, or 3 and not eligible for curative resection. IDH1 mutant status will be determined during pre-screening/screening phase. Participant must have radiographic progression/recurrence of disease according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) and have received 0 to 1 prior systemic treatment regimen in the advanced/metastatic setting for conventional chondrosarcoma. The primary endpoint is progression-free survival (PFS) in Grades 1 and 2 participants. Key secondary endpoints are PFS in all randomized participants, overall survival (OS) in Grades 1 and 2 participants, and OS in all randomized participants. Participants who meet enrollment criteria will be randomized 1:1 to receive oral ivosidenib 500mg once daily, or a matching placebo once daily.
Taking part in medical research usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This study will admit a wide range of data on the clinical trial experience of chondrosarcoma patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future chondrosarcoma patients.
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.
The project is planned as a phase II clinical trial with a low level of intervention, for the prospective evaluation of the clinical results of radical or adjuvant treatment by proton therapy in chordomas and chondrosarcomas of the skull base using hypofractionation schemes in 5 fractions, with the aim of consolidating the scientific evidence that exists with high-precision techniques with photons, increasing this evidence by adapting this treatment scheme to the proton technique. In addition, a cross-sectional prospective evaluation of the quality parameters of the dosimetry of hypofractionated proton therapy and an evaluation of the quality of life of these patients will be carried out. - Primary Objective 1. - Toxicity according to CTCAE-v5 criteria 2. - Local control determined by Magnetic Resonance with Gadolinium. - Secondary Objectives 1. To evaluate the quality of life of the patients, 3 months after the end of the treatment, using a specific questionnaire. 2. To evaluate the dosimetric benefits using techniques that allow an improvement in the dose gradient, improving the coverage of the CTV (Clinical Tumor Volume) and decreasing the dose in surrounding risk organs.
This phase II trial compares the effect of immunotherapy with ipilimumab and nivolumab alone to their combination with cabozantinib in treating patients with soft tissue sarcoma that has spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply and may also prevent the growth of new blood vessels that tumors need to grow. By these actions it may help slow or stop the spread of cancer cells. Adding cabozantinib to the combination of ipilimumab and nivolumab may be better in stopping or slowing the growth of tumor compared to ipilimumab and nivolumab alone in patients with advanced soft tissue sarcoma.
The objective of this study is to describe adherence to a personalised home exercise program in patients undergoing resection and reconstruction of lower limb for bone tumor and neoadjuvant chemotherapy treatment in the first six months after surgery intervention and investigate possible prognostic factors.
The Registry For Children, Adolescents And Adults With Osteosarcoma And Biologically Related Bone Sarcomas (COSS-Registry) is a non-interventional, multicentric, international, clinical and epidemiologic patient registry. The COSS-Registry collects key data on osteosarcomas or biologically related bone sarcomas. With that data collection we want to gain new scientific insights and results about this tumor disease, prognosis, surveillance and long-term effects. Besides the data collection we would also like to foster the collection of biomaterial (tumor specimen and blood samples) for scientific research. The stored material will be used to perform cell and molecular biological analyses to identify the causes of osteosarcoma, the prognosis and possible new treatment options. As a starting point the donated biomaterial of registered patients will be analyzed firstly for the presence of a tumor predisposition by germline mutations. In case of detected genetic variations that are related to the tumor disease and which may affect the patient's health and follow-up care (because of the potentially increased risk of developing other malignant tumors), affected patients will be informed and referred to genetic counseling. Registry patients will be asked at the time of diagnosis if they wish to be informed about germline variants detected as part of the study procedures.
Periosteal chondrosarcoma is a low-grade, malignant cartilaginous bone neoplasm that arises on the surface of bone, predominantly in the metaphysis of long bones. Periosteal chondrosarcoma is an infrequent chondrosarcoma subtype which accounts for less than 1% of all chondrosarcomas (1) and has a peak incidence in the fourth decade (2). It has a reported incidence of local recurrences of 13-28% and a low metastatic potential, with distant recurrences occurring mostly in lungs (3). Contrary to conventional chondrosarcomas, grading of periosteal chondrosarcomas seems not to predict prognosis. IDH1 and IDH2 mutations, characteristics of central chondromas/chondrosarcomas, have been also found in a subset of periosteal chondrosarcomas (1, 4). These observations are based on the results from smaller series of cases (1, 5, 6), although the impact of histopathological characteristics on survival, local recurrence and metastases should be assessed in larger series of cases. The aim of the present study is to review all the cases with a diagnosis of primary periosteal chondrosarcoma treated at the Rizzoli Institute from 1900 up to 31 December 2019, retrospectively. The study will exam all the clinical, radiological, and histological features of this tumor with regard importance of medullary involvement, the IDH1/2 gene status, the types of treatment, the status of surgical margins, the presence of progression (dedifferentiation) areas and the relationship of these factors to individual outcome.
