Filter by:The purpose is to evaluate if sodium fluoride PET in patients having already undergone a choline PET negative for bone extension (non-metastatic status) modifies the status of patients concerning the existence or not of bone metastases. Secondary purposes are: - To evaluate if detection of bone metastasis by sodium fluoride PET, not detected by choline PET, leads to change of treatment - To evaluate inter-technique concordance (choline vs sodium fluoride PET) of results (metastatic status and number of lesions) - To evaluate the inter-judge concordance of interpretation of sodium fluoride PET - To study the discordance of metastatic status of 2 techniques.
Rationale: Bone metastases arise in 50% of all patients dying from carcinoma, increasing up to 70% in patients with breast and prostate cancer. The lesions can cause pain and fractures, leading to diminished quality of life and poorer survival. Current knowledge concerning adequate, personalized treatment of metastatic lesions of the long bones in patients with disseminated cancer is insufficient and inconclusive due to lack of large, prospective series with patient reported outcome measures. Objective: The OPTIMAL cohort aims to describe the quality of life and pain perception of patients after local treatment (radiotherapy and/or surgery) of metastases of the long bones, for both the entire cohort as well as for specific treatments separately. With this a more personalized treatment for metastases in the long bones based on expected survival and impending fracture risk can be provided in order to improve functioning and the quality of life for the remaining lifetime in patients with disseminated cancer. Study design: Observational, prospective, multicentre cohort study. Study population: All patients with metastases of the long bones visiting a radiation oncologist or orthopaedic surgeon. Main study parameters/endpoints: Primary endpoints are patient reported quality of life (including functioning) and pain levels. Complications and survival are secondary endpoints. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients in the OPTIMAL cohort will perhaps not directly benefit from their participation. Participation will contribute to deriving patient-specific treatment modalities for future patients with bone metastases of the long bones. Risks associated with participation in the prospective cohort are considered negligible due to the observational nature of the study. The burden for the patients lies in completion of questionnaires, which is considered to be in proportion with the potential value of this research.
The clinical trial is a stage 3 study to determine the role of fentanyl transmucosal in the prevention of pain induced by mobilization in patients receiving a bone metastasis radiation for bone metastasis irradiations
Bone metastasis causes bone destruction and skeletal related events (SRE) including compression fracture, hypercalcemia, and spinal cord compression. Therefore, palliative treatments for pain control and local control have become important and multidisciplinary multimodality approach is needed for treatment of bone metastasis. The efficacy of radiotherapy (RT) for bone metastasis is well known. And the results that bisphosphonate decreases SRE in patients with solid tumor and multiple myeloma reported. In previous retrospective reports, the combination of local RT and systemic bisphosphonate was more effective than RT alone. Therefore, the investigators designed a phase II study to evaluate the efficacy of RT in combination with zoledronic acid on pain relief and the safety of RT in bone metastasis patients with gastrointestinal tumors.
