Active clinical trials for "Bone Neoplasms"

This phase I trial studies the side effects and best dose of cord blood-derived expanded allogeneic natural killer cells (donor natural killer [NK] cells) and how well they work when given together with cyclophosphamide and etoposide in treating children and young adults with solid tumors that have come back (relapsed) or that do not respond to treatment (refractory). NK cells, white blood cells important to the immune system, are donated/collected from cord blood collected at birth from healthy babies and grown in the lab. Drugs used in chemotherapy, such as cyclophosphamide and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving NK cells together with cyclophosphamide and etoposide may work better in treating children and young adults with solid tumors.

Aim of the study is to assess efficacy of a short course radiation treatment in patients with complicated bone metastases

New drug efficacy in ES has been disappointing in the last decades and no new drugs have been successfully introduced up to now in front line treatment. Among the tested drugs, early clinical data suggest that strategies using multi-targeted tyrosine kinase inhibitors (TKI) with anti-angiogenic activities are among the most efficient and may be beneficial in the treatment of patients with ES. Several TKI have been and are currently being tested as single-agent in patients with relapsed/refractory ES with encouraging results in phase II trials. Regorafenib has shown promising activity in Ewing sarcoma relapse setting, Nevertheless, regorafenib has never been combined with the intensive chemotherapy VDC/IE schedule and therefore this combination needs to be evaluated in order to avoid dose reduction of the current standard treatment and hence its efficacy. The current clinical trial has been therefore designed to test the feasibility of regorafenib with ES conventional chemotherapy. It consists of a phase Ib that will only recruit patients with multi-metastatic (other than lungs/pleura only) ES, that present the highest unmet medical need (2 year EFS: 33%, similar to patients with relapse/refractory ES).

The purpose of this study is to investigate whether zoledronic acid-loaded bone cement (4mg ZOL+ gentamicin PMMA ) as adjuvant method can decrease local recurrence in patients with giant cell bone tumor following intralesional curettage surgery. The hypothesis is that patients with local administration of zoledronic acid to the bone cement has lower relapse rate compared those with traditional bone cement(gentamicin PMMA ).

The purpose of the clinical study is to investigate whether the local delivery of bisphosphonate as a surgical adjuvant can decrease the chance of a giant cell tumor of bone coming back to the same location. The hypothesis is that the local administration of bisphosphonate will decrease the rate of the tumor returning compared to traditional aggressive surgical removal of the tumor.

To investigate, whether multi-fraction stereotactic body radiation therapy (SBRT) within 3 treatment fractions is non-inferior to the current standard of care of 5 fraction SBRT regarding pain response at 3 months after radiotherapy.

The purpose of this study is to assess toxicities of FLASH radiotherapy treatment and pain relief in subjects with painful thoracic bone metastases. FLASH radiotherapy is radiation treatment delivered at ultra-high dose rates compared to conventional radiation treatment.

Spinal metastases account for 60% of all malignant bone metastases and represent a medically important treatment goal. For patients with malignant tumors diagnosed at this stage, performing En bloc spondylectomy with wide margin of resection facilitate the improvement in quality of life including ambulatory ability, daily activities independence and attenuation of bone pain. However, En bloc spondylectomy is a major operation with long operation time and frequent hemodynamic instability during the operation. Therefore, the anesthetic care plays an important role and an enhanced recovery after surgery (ERAS) is the goal. For the ERAS anesthesia protocol for En bloc spondylectomy, we propose two major components to achieve this goal: (1) an encephalographic spectrum guided multimodal anesthesia combined with ultrasound-guided nerve block and (2) the advanced machine-learning algorithm index, namely the hypotension predictive index (HPI) guided hemodynamic protocol.

18F-sodium fluoride (18F-NaF) was already investigated numerous times in the last 40 years as a PET alternative to standard 99m-technetium-derived bone scintigraphy. However, lack of universal tracer availability and higher costs contributed to the failure of 18F-NaF to systematically supplant bone scintigraphy as a standard of care. Recently, an isotope shortage crisis occurred and evidenced the need to have non-reactor-derived alternatives for many nuclear medicine procedures, including bone scintigraphy. Since 18F-NaF is cyclotron-produced, it could become a necessary alternative to bone scintigraphy in case of another worldwide isotope shortage. The study aims to evaluate the safety profile of 18F-NaF injection. Moreover, a patient registry will be compiled in order to perform sub-studies on 18F-NaF diagnostic performance on diverse bone and articular diseases.

To evaluate the current medical practice and its influence on health-related quality of life, in patients who are treated with injectable bone antiresorptive drugs (biphosphonates or denosumab) for at least one year.
