Filter by: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.
The purpose of the study is to investigate effectiveness of stereotactic body radiotherapy in patients with bone metastatic disease.
Bone metastases are frequent distant manifestations of cancer, with pain as a common and devastating consequence. The primary treatment for painful bone metastases, external beam radiation therapy, is moderately effective: about 60% of patients who undergo conventional radiotherapy experience (partial) pain relief. Several factors associated with treatment failure have been identified, but no attempts have been made to collapse these factors into a clinically useful prediction tool to predict treatment response. In addition, to aid in therapy selection based on expected survival time, development of survival models is essential. Finally, we need innovative treatments as alternatives or additive to standard treatment options to improve quality of life (QoL). For these reasons, we set up the PRESENT cohort study, recruiting patients at the departments of radiation oncology and orthopedic surgery. We aim to provide detailed information about clinical data, create an infrastructure for efficient, fast and pragmatic evaluation and implementation of innovative interventions, as well as development of accurate new prediction tools.
This pilot clinical trial studies how well copper Cu 64-tetra-azacyclododecanetetra-acetic acid (DOTA)-trastuzumab positron emission tomography (PET) works in predicting response to treatment with ado-trastuzumab emtansine in patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer that has spread to other places in the body. Copper Cu 64-DOTA-trastuzumab is a chemotherapy drug (trastuzumab) attached to a radioactive substance. Diagnostic procedures using PET may allow scanners to take pictures of where the drug travels in the body and may help doctors identify which patients may benefit from treatment with ado-trastuzumab emtansine.
This study will examine biomarkers involved in osteomimicry in bone metastases and circulating tumor cells (CTCs) of men with mCRPC before and during therapy with the bone-targeting radiopharmaceutical radium-223. This study will also examine the bio-distribution of radium-223 in bone and bone metastases of men with mCRPC. The investigators hypothesize that bone metastases and CTCs in men with mCRPC will commonly express markers of EMT/plasticity and osteomimicry, not just in the normal surrounding osteoblastic stroma but in the epithelial tumor cells themselves and that radium-223 will target both of these compartments including the more mesenchymal/osteoblastic tumor cells and the surrounding osteoblasts in the active bone microenvironment, with a relative sparing of normal bone and bone marrow.
The goal of this clinical research study is to learn if 1 large dose of radiation therapy is better at controlling pain from cancer that has spread to the bones than 10 smaller doses of radiation. Researchers also want to learn if 1 large dose of radiation therapy can help decrease the use of drugs to control the pain, and if it can help to control the disease.
The aim of the trial is to test the hypothesis that the benefit of denosumab is maintained if administered only every 12 weeks as compared to every 4 weeks.
This study will evaluate baseline uptake on a FDG PET/CT scan in patients with breast cancer that has spread to the bones. A repeat FDG PET/CT scan will be done 4 weeks after the start of new breast cancer hormone treatment and again at 12 weeks after treatment start. The baseline uptake and change in uptake after the repeat scans will be compared to clinical long term outcomes such as time to progression and overall survival. In addition the uptake will be compared to the incidence of skeletal related events that are common occurrences in patients with cancer that has spread to the bones.
This pilot clinical trial studies fludeoxyglucose F18 (FDG)-positron emission tomography (PET) in imaging patients with prostate cancer treated with ranolazine. Diagnostic procedures, such as FDG-PET, may help find prostate cancer and find out how far the disease has spread. Giving ranolazine may enhance FDG-PET imaging by increasing the amount of glucose available for uptake by the scan.
The aim of this study is to evaluate effectiveness of the Philips Sonalleve MR-HIFU device for the palliation of pain in patients with bone metastases. Magnetic Resonance Imaging-guided High Intensity Focused Ultrasound (MR-HIFU) uses ultrasound to palliate pain caused by bone metastases. The main palliative mechanism of the method is due to local bone denervation, caused by the heat denaturation of the periosteum layer in the treated area. The importance of this therapy is that it offers a non-invasive, focal therapy, avoiding side-effects to surrounding normal tissue that occur with radiation therapy or the need for needle insertion as with radio-frequency(RF)ablation. The study hypothesis is that MR-HIFU will be effective in treating the pain associated with bone metastases
