Active clinical trials for "Bone Neoplasms"

The outcome of patients with metastatic Ewings Sarcoma is poor with current standard of care chemotherapy, with less than 30% survival. Based on recent encouraging pediatric literature we have designed this trial to improve the outcome of patients with metastatic Ewings sarcoma using Irinotecan and Temozolomide in addition to standard chemotherapy.

The giant cell tumor (GTC) is an aggressive benign bone tumor, growing at the metaphyseal-epiphyseal regions of long bones, especially around the knee and the distal radius.It is responsible for bony destruction in para-articular zone fracture and leading to the breakdown and destruction of the underlying joint. Histologically, the tumor cell contains a contingent of monocytic cells round, a contingent of giant type cell of type osteoclastic responsible for bone resorption that accompanies these tumors and a contingent of lengthened cells fibroblast-like considered to be contingent tumor. The treatment is exclusively surgical; or by resection of the lesion which takes away tumour and its environment, solution which, if it prevents local recurrence, imposes an important bony and articular reconstruction, always limited and deteriorating rapidly over time in these young patients; or by curettage of lesion, by "hollowing-out" of the bone, creating a hole which it will be necessary to fill up by a bony grafting or a substitute of the bone (cement). This last solution, if it preserves a better function, exposes at risk of local recurrence,putting into play the prognosis of articulation near, most often the knee.Despite different local adjuvants treatments used during surgical operation, after having curetted the cavity and before filling it up, the recidivism rates vary from 12 % to 41 % (average 25 %) in literature. The beneficial effect of the adjuvants therapeutics suggests the concept broadly accepted by a tumoral microscopic residual at the origin of the local recidivism .Biphosphonates (BP) is molecules which settle in vivo on the hydroxyapatite of the bone; they inhibit the recruitment of the osteoclast forerunners and the activity of mature osteoclast. Besides, biphosphonates containing some nitrogen (N-BP), leads to the apoptose of mature osteoclast. These molecules also have a direct effect on tumor cells , causing apoptosis of neoplastic cells of myeloma, of breast cancer. Clinical controlled studies confirm the experimental data of N-BP. Two work also showed their effect on osteoclasts and stroma cells of tumours with giant cells but no clinical study assessed potential on the prevention of the local recurrence. The investigators offer a study phase 2 of the effectiveness of N-BP (acid zoledronique) on the prevention of the local recurrence of tumours with primary huge cells after surgical treatment by curettage - filing by a surgeon referent in oncologic orthopedic surgery. Number of patients: 24

This study will evaluate the clinical response and safety of cone beam computed-tomography guided percutaneous cryoablation in bone metastases from thyroid, adrenal and neuroendocrine tumors in 30 patients.

This is an open label, pharmacodynamics, intrapatient dose escalation phase 1B study.

This phase I trial studies the side effects and best dose of hydroxychloroquine in treating patients with solid tumors undergoing radiation therapy for bone metastases. Drugs, such as hydroxychloroquine, may make tumor cells more sensitive to radiation therapy

Massive bone tumour resection is often associated with important postoperative bleeding. This may determine systemic (anaemia), as well as local complications (wound healing, seroma, haematoma). The objective of this study is to determine whether the use of topical tranexamic acid or topical Evicel® will reduce the perioperative bleeding comparing it with usual haemostasis.

This is a multicenter, randomised phase II trial in patients with high risk GCT. Primary objective: Determine if adjuvant zoledronic acid improves the 2 years recurrence rate of 'high risk' GCT as compared to standard care Secondary objectives: Determine the relapse free survival Evaluate the usefulness of bone remodelling markers in diagnosing and monitoring GCT

Translational research aimed at improving diagnostic accuracy of musculoskeletal infection and musculoskeletal tumours using machine learning applied to clinical data, histopathological sections and genomic sequencing.

The aim of the study is to describe, through a minimum follow-up of 18 months, the quality of life of patients undergoing salvage surgery of lower limb for musculoskeletal tumors and to identify possible prognostic factor correlated. Quality of life will be evaluated with Bt-DUX (Bt=bone tumor)

Fitting into the group of 90 cases of this study was to henan tumor hospital bone prosthesis replacement of surgical treatment of bone malignant tumors patients, evaluate watch trill to be bone prosthesis replacement surgery treatment of malignant bone tumor patients perioperative anxiety, depression, pain, explore watch trill to bone prosthesis replacement surgery treatment of malignant bone tumor patients of postoperative complications.
