Active clinical trials for "Bone Neoplasms"

The aim of this study is to identify demographic & disease characteristics in pediatric oncology patients diagnosed with soft tissue & bone tumors involving the extremities & treatment outcomes in these patients.

If cancer spreads to bones it can be very painful, especially when trying to move around. One of the best treatments is radiotherapy, which has to be given in a cancer centre. Even with this treatment, only about half of people will get good pain relief, and that can take up to 6 weeks to work fully. If we know who is unlikely to benefit , then we can explore other forms of pain relief sooner, without having to go through radiotherapy unnecessarily. We have found that there may be a very simple way to identify patients likely to get good pain relief, using a test of changes in temperature sensation over the painful bone. This study will explore whether this simple bedside test can be used in a community setting to identify which patients suffering from cancer induced bone pain will get good pain relief from radiotherapy.

The aim of the present study is to identify deregulated miRNAs in oncological patients with bone metastases present within the circulating exosomes and responsible for the biological mechanisms involved in the process of bone metastasis, in order to obtain a panel of biomarkers predictive of this risk. Through appropriate molecular screening methods a specific panel of significantly deregulated miRNAs will be identified; subsequently bioinformatics analyzes through the use of dedicated databases will be carried out, based on literature data and predicted protein targets in order to identify their potential role in tumor progression, and especially in the onset of bone metastases. Attention, therefore, may be focused on the individual miRNAs identified through individual analysis analyzes of gene expression. These biomarkers could also serve as therapeutic targets, allowing to improve the effectiveness of current therapies and to undertake timely and appropriate therapeutic choices, developed on the basis of the patient's molecular characteristics

Cancer which has spread to the bone, causing bone metastases (bone tumours) can weaken bone health and increase risk of fractures (breaks). Consequently, patients can be unsure whether to exercise and health professionals can be unsure what exercise advice is suitable. Despite this, it is well known that exercise improves quality-of-life for patients with bone metastases and therefore it is important that exercise is prescribed to these patients. This study aims to increase understanding of the link between daily exercise and risk of fracture in patients with bone metastases.

The aim of this study is to identify demographic & disease characteristics in pediatric oncology patients diagnosed with Ewing Sarcoma Family of Tumors (ESFT) & treatment outcomes in these patients.

This is a retrospective observational real-world study, which evaluates the efficacy and safety of denosumab and non-denosumab therapies in the treatment of Chinese populations of surgically unsalvageable or severe post-surgery morbidity associated giant cell tumor of bone (GCTB), collectively referred to as unresectable GCTB, during 2013-2021 in three medical centers, serving as the external control for a single arm phase Ib/II trial on JMT103 treatment of GCTB. 301 patients were enrolled and divided into 2 groups according to their actual previous exposures. Group 1 (n=135) was denosumab group. Group 2 (n=166) included two types of exposures other than denosumab: other anti-GCTB drug therapies, or no therapy on GCTB patients. The dosage, route, frequency and other administration methods was collected according to the actual previous treatment records. The primary outcome measure was the tumor response rate [radiographic tumor response (CR/PR evaluated by ICDs or EORTC criteria) within 12 weeks, or at least 90% reduction of osteoclast like giant cells compared with baseline]. The key secondary endpoint was the tumor response rate [radiographic tumor response (CR/PR evaluated by ICDS or EORTC criteria), or at least 90% reduction of osteoclast like giant cells compared with baseline]. Other secondary Outcome Measures include: proportion of patients whose tumors was surgically resectable; median duration of tumor response (DOR), disease control rate (DCR), and time to disease progression (TTP); and types and proportion of key adverse reactions.

Setting: Oral mucositis is a very common complication of cancer treatment, accounting, often at increased risk for infections and even the interruption of treatment, interfering with the prognosis of the disease. The low intensity laser therapy has been proposed as an alternative for the treatment and prevention of this side effect, with good results in terms of clinical and functional, speeding up the process of wound healing and reducing pain. Objective: To evaluate the effectiveness of using low power laser in the prevention of oral mucositis in patients with hematological cancer, undergoing chemotherapy for bone marrow transplantation. Methods: There will be a Clinical Trial Randomized, double-blind study to evaluate the effectiveness of using low power laser in the prevention of oral mucositis in patients with hematological cancer, undergoing chemotherapy for bone marrow transplantation. Participate in the study, patients who are in the condition mentioned above accepting participate and have aged over 18. Will be excluded from the study patients who have autoimmune disease, which present sensitivity to laser or who have already started treatment for oral mucositis prior to this study.The study variables are:-independent variable: whether or not the red laser of low power-dependent variables: oral mucositis, degree of mucositis, chemotherapy regimen, type of blood cancer. For determining the association between the independent variable and the dependent will be used chi-square tests of association (Pearson) and Fisher's exact test, if necessary. Will calculate the risk ratio (RR) as a measure of relative risk, with the confidence interval at 95% (IC95%).Also be calculated NNT (number needed to treat to obtain benefit) and NNH (number needed to harm getting). Will be adopted a significance level of 5%. The project was approved by the Ethics and Research iMIP. All patients will be appropriately informed about the objectives of the project and will only be included if they voluntarily agree to participate by signing the consent form. Keywords: laser, prevention and control; oral mucositis, bone marrow transplant.

The purpose of this study is to compare 18F-Fluoride PET bone scans to traditional 99mTc-MDP bone scan to determine if one is better for diagnosing bone metastases.

The purpose of this study is to determine if denosumab is non-inferior to zoledronic acid in the treatment of bone metastases in subjects with advanced breast cancer.

In this study a previously described structured multimodality image report system for the characterization of focal bone lesions is evaluated in a larger patient population. The objective of this study is to evaluate the performance of this tool stratifying the malignancy risk of bone tumors.
