Using sensitive markers (such as thyroglobulin, etc) to evaluate the efficacy of strontium-89 chloride (Sr-89) in differentiated thyroid cancer with bone metastases with an aim to breaking out of its palliation effect for bone pain.
The primary aim of the study is to investigate the effects of supervised exercise, telerehabilitation and home-based exercise on patient perception in patients who have undergone bone tumor resection. The secondary aim of the study is to identify the barriers to starting exercise in these patients.
This is a prospective, single-center, randomized study directly comparing outcomes after MR guided high intensity focused ultrasound (MR HIFU) or external beam radiation therapy (EBRT) treatment of painful bone metastases.
In the treatment of malignant bone tumors, it may be necessary to remove large areas of the femur. To replace these large parts of missing bone, a prosthesis can be used. One innovative technology developed by Biomet is the Compress® Compliant Pre-Stress System (CPS; Zimmer-Biomet, Warsaw, USA). This fixation device uses compression, via a short traction bar, to stimulate osteointegration at the bone-prosthetic interface, promote hypertrophy of the loaded bone, and avoid stress bypass of the host bone around a stiff intramedullary stem. Young patients cured of tumors have a long life expectancy and a compelling need for prosthetic fixation that is equally durable. Good bone fixation is a prerequisite for implant longevity. Although the initial results are encouraging, there is a need for additional mid- to long-term survival data from larger patient series showing longevity of the system, as well as reporting of functional outcome. Furthermore, to the best of our knowledge, no study examining the survival of the device using prospective data already exists. In addition, no studies were found examining the quality of life of the patients with the CPS system.
The great promise of PET/MR for assessment of skeletal metastatic involvement is derived from the extensive experience with stand- alone MR, but initial data on the use of PET/MR for assessment of bone pathology indicate that PET/MR introduces unique issues that should be addressed when determining its role in this clinical scenario. In this study cohort includes 150 patients 18 years or older, having metastatic skeletal involvement on baseline PET/CT prior to treatment. Baseline studies and follow up studies of the patients referred post treatment, will be reviewed. The main goal of the study is to asses the accuracy of PET/MR in detection and monitoring response of bone metastases.
Bone radioiodine (RAI) uptake without structural abnormality in thyroid cancer (TC) patients may be related to false positive or to microscopic foci of metastatic tissue. In such cases, outcome is reported to be excellent. Indeed, Robenshtok et al. reported a serie of patients with RAI-avid bone metastases of TC without structural abnormality on imaging studies who have more favorable long-term prognosis than those harbouring structurally visible bone metastases and do not undergo skeletal-related complications. The investigators report the case of Mrs D., who had been operated for a pathologic tumor stage 3: pT3(m) poorly differentiated TC at the age of 43. The first post-therapeutic whole body scan revealed 3 foci of bone uptake (right clavicle, L2, L3). The elevated level of thyroglobulin (157ng/mL) favoured the hypothesis of bone metastases despite the absence of any structural lesion on CT and MRI. She received 7 courses of radioiodine therapy. The right clavicle RAI uptake persisted, and subsequent CT disclosed an osteolytic lesion which was treated by radiofrequency and external beam radiation. Twenty-five years after the diagnosis, she has a persistent morphological disease with a 30x8mm progressive lesion on the right clavicle, for which surgery is planned. The aim of the present study is to describe the natural history and evolution of radioiodine avid bone metastases from thyroid cancer without structural abnormalities and to identify prognosis factors.
In the present study, we will prospectively evaluate the pain response and treatment failure rate to determine the most favorable radiation dose in single fraction stereotactic radiotherapy using the modern highly conformal technique for bone metastases. Our findings should be able to provide evidence-based recommendation to support the utilization of single fraction radiotherapy for value-based oncology practice.
Bone metastases appear in many cancers. They are associated with severe pain that is refractory to standard treatment. Improving the quality of life and better pain relief is therefore an essential goal of the treatment of metastatic disease. The most common site of long bone metastases is the superior femoral epiphysis. The usual management of patients with bone metastases in the superior femoral epiphysis is based on gamma implant osteosynthesis when there is a known risk of fracture (Mirels score> 8). Nonetheless this surgery is only accessible to a few patients because of the associated morbidities. Percutaneous cementoplasty has been developed to treat patients who are not eligible for conventional surgery. It consists in a filling of the bone cavity created by metastasis using an acrylic resin. However, these approaches do not completely prevent the risk of upper femoral epiphyseal fracture due to the low mechanical resistance of the resin to shear movements. The Y-STRUT® implantable medical device was developed to overcome this risk of superior femoral epiphyseal fracture by the biomechanical strengthening of the proximal femur in addition to cementoplasty. It has been successfully tested in more than 70 patients with cancer but access to reimbursement and the APHP market have been postponed due to lack of sufficient clinical evidence. The investigators propose this prospective phase 2a study in order to provide evidence of the performance of the Y-STRUT® implant.
This is an interventional randomized controlled trial that will compare patients who underwent segmental hip replacement using mega-implants with either porous collar or porous collar with HA. Patient recruitment will continue for 18 months. Parameters to be investigated are radiographic measures of bone incorporation into the implants, as well as patient functional outcomes. Clinical follow-up will last for 24 months for each patient.
