Active clinical trials for "Bone Neoplasms"

The aims of this work were to assess the feasibility, efficacy, short-term outcome and safety of microwave ablation in the treatment of malignant bone, lung and renal tumors.

This purpose of this study is to assess the feasibility of FLASH radiotherapy for the palliative treatment of painful bone metastases. FLASH radiotherapy is radiation treatment delivered at ultra-high dose rates compared to conventional radiation treatment.

Primitive malignant bone tumor or mixt tumor (compounded of soft tissues and bone) is a rare pathology particularly within the pelvis, the sacrum or the hip (between 25 and 80 new cases in France per year). The reference treatment is a surgical "en bloc" resection associated or not to a medical treatment. This surgery remains highly challenging because of the complex three-dimensional geometry of the pelvic bone and the proximity of important organs and neurovascular structures. The local recurrence rate is significantly increased when the resection does not respect a safe tissues margin (R0 margin). A new technology has been developed and used in different reference sites the Patient Specific Instrument (PSI), manufactured by 3D-Side. The PSI allows for a more secure and reliable surgical gesture, leading to more frequent R0 margins. The main objective of this study is to compare the efficiency of the PSI for bone tumor resections within the pelvis with respect to the reference method.

The purpose of the study is to investigate effectiveness of stereotactic body radiotherapy in patients with bone metastatic disease.

Literature has shown that hypofractionated radiotherapy regimens are efficacious in patients with complicated bone metastases and have a low potential for severe treatment-related toxicities. There is a clear need for hypofractionated schedules in the complicated bone metastases population, especially when considering the overarching aim of palliative radiotherapy and the clinical features of this patient population. As well, current research examining hypofractionated approaches in bone metastases patients with impending or pathologic fractures, neuropathic pain or accompanying soft tissue masses has been markedly scarce.

Pain from bone metastases of breast cancer origin is treated with localized radiation. Modulating doses and schedules has shown little efficacy in improving results. Given the synergistic therapeutic effect reported for combined systemic chemotherapy with local radiation in anal, rectal, and head and neck malignancies, the investigators sought to evaluate the tolerability and efficacy of combined capecitabine and radiation for palliation of pain due to bone metastases from breast cancer Hypothesis: Given the hypothesis that regimens employing greater intensity radiation yield higher rates of pain relief, radiosensitization using a tumor targeted drug like Xeloda should improve the rate of complete pain relief as compared to radiosensitization with 5FU alone. Primary Objective: To determine the frequency and duration of pain relief and narcotic relief for the proposed regimen. Secondary Objective: To determine the toxicity of concurrent Capecitabine and radiotherapy in breast cancer patients with bone metastases.

The goal of this study is to collect comparative data on safety and efficacy of MR Guided Focused Ultrasound and External Beam Radiation for treatment of metastatic bone tumors or multiple myeloma.

Highly selective irradiation requires accurate target definition by high-resolution three-dimensional imaging. Co-registration of FDG-PET and high-resolution CT might be the imaging modality of choice. This choice might target radiation therapy precisely to the intra-osseous volume that is responsible for pain and to spare selectively healthy bone in the vicinity of the metastasis. This strategy could result in equal anti-pain efficacy as conventional large volume radiotherapy, but could allow bone remodeling and preservation of bone structural strength in the vicinity and could lead to reduced toxicity to neighboring organs.

A multicenter prospective study to assess the efficacy and safety of ZOMETA® in treatment of high-level NTX non small cell lung cancer with bone metastasis.

Zoledronic acid (Zometa) belongs to a class of drugs called bisphosphonates. Bisphosphonates are used in bone metastases to keep the cancerous lesion under control in the bone and to help prevent calcium level elevations in the blood. Cancer cell-culture studies at the Cleveland Clinic showed that zoledronic acid and radiation together have more cell killing effect than either one used alone. The purpose of this study is to monitor the healing of bone lesions when using zoledronic acid together with radiation treatment.
