Active clinical trials for "Chondrosarcoma"

Phase I/II multicenter and prospective trial of nilotinib and adriamycin as neoadjuvant treatment in liposarcomas and leiomyosarcomas of retroperitoneum. The main objective of this study is to improve relapse-free survival (RFS)and overall survival (OS) decreasing from 50% to 30% the relapse percentage at 5 years in patients with resected sarcoma of retroperitoneum. Secondary objectives include the analysis of antitumoral activity through response rate (RECIST and tissular changes), the assessment of positive correlation between biomarkers and clinical results, the study of long term overall survival, and the analysis of the safety profile of the nilotinib-adriamycin combination. The trial hypothesis is that the nilotinib-adriamycin combination is synergistic and therefore better response results are expected (from 20% as P0 to 40% as P1). The study seeks to find a positive correlation between biomarkers and clinical results in retroperitoneal liposarcoma and leiomyosarcoma treated with the mentioned combination. The study involves the participation of 20 hospitals of the Spanish Sarcoma Group (GEIS). The treatment consists of 4 neoadjuvant cycles of nilotinib-adriamycin on patients with resectable retroperitoneal sarcoma. The research comprises a robust translational study as well as histological and radiological reviews.

The purpose of this study is to collect information from medical records to see what effects proton beam radiation has on cancer and analyze possible side effects.

This application proposes a prospective clinical trial to evaluate the impact of adding a focused physical therapy (PT) intervention to the preoperative regimen of individuals diagnosed with a malignancy of the lower extremity (LE). The primary aim will be to determine if individuals diagnosed with a malignancy of the LE can participate in a 10 week preoperative strengthening, stretching, and aerobic exercise regimen.

Forty patients with advanced pancreatic cancer, osteosarcoma, soft tissue sarcoma, and breast cancer will receive DeltaRex-G intravenously at a dose of 1-4 x 10e11 colony forming units (cfu) or equivalent 0.6-1.8 x 10e10 RV copies per dose one to three times a week. DeltaRex-G may or may not be given with one or more FDA approved cancer therapies/immunotherapies. Based on previous Phase 1/2 US based clinical studies, DeltaRex-G does not suppress the bone marrow or cause serious organ dysfunction, and enhanced immune cell trafficking in tumors may cause the tumors to appear larger or new lesions to appear on CT, PET or MRI. Further, tumor stabilization/regression/remission may occur later during the treatment period. Therefore, DeltaRex-G will be continued regardless of CT, PET or MRI results if the patient has clinical benefit and does not have symptomatic disease progression.

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.

single institution cases series review of histological, radiological and clinical data

The purpose of this project is to verify possible clinical and radiological findings with regard to distinguishing enchondroma from low grade chondrosarcoma of the long bones. In addition, this study presents the outcome of patients with enchondroma and low grade chondrosarcoma of the long bones who were treated with curettage (intralesional surgery).

Patients with a diagnosis listed under "conditions" below are eligible to be considered for the EAP. These conditions must be serious or life-threatening at the time of enrollment and appropriate, comparable, or satisfactory alternative treatments must have been tried without clinical success. Patients with conditions not listed under "conditions" below are not eligible for the tazemetostat EAP.
