Filter by:The goal of this clinical trial was to assess the diagnostic performance and safety of Sodium Fluoride F-18 Positron Emission Tomography / Computed Tomography (18F-NaF-PET/CT) in bone metastases of malignant tumors compared with Technetium[99mTc] Methylenediphosphonate Bone Scintigraphy ± Single Photon Emission Computed Tomography (99mTc-MDP-BS±SPECT). The enrolled subjects were randomly assigned to two sequences A and B at a ratio of 1:1. Within 7 days, 18F-NaF-PET/CT and 99mTc-MDP-BS±SPECT bone imaging were performed alternately. The sensitivity, specificity, positive and negative predictive value of 18F-NaF-PET/CT and 99mTc-MDP-BS±SPECT were calculated respectively based on the diagnostic data of standard of truth.
Fitting into the group of 90 cases of this study was to henan tumor hospital bone prosthesis replacement of surgical treatment of bone malignant tumors patients, evaluate watch trill to be bone prosthesis replacement surgery treatment of malignant bone tumor patients perioperative anxiety, depression, pain, explore watch trill to bone prosthesis replacement surgery treatment of malignant bone tumor patients of postoperative complications.
The purpose of this study is to investigate whether zoledronic acid-loaded bone cement (4mg ZOL+ gentamicin PMMA ) as adjuvant method can decrease local recurrence in patients with giant cell bone tumor following intralesional curettage surgery. The hypothesis is that patients with local administration of zoledronic acid to the bone cement has lower relapse rate compared those with traditional bone cement(gentamicin PMMA ).
The purpose of this study is to assess toxicities of FLASH radiotherapy treatment and pain relief in subjects with painful thoracic bone metastases. FLASH radiotherapy is radiation treatment delivered at ultra-high dose rates compared to conventional radiation treatment.
non-intervention、real world study； Effect of timing and regular treatment of zoledronic acid on the incidence of SREs in breast cancer patients
In the population suffering from cancer, children and teenagers are in the majority. For children with rapid development of body and mind, with the change of cognitive ability, they will feel anxiety and fear about the expected potential negative events. Painting art therapy is a kind of non-verbal psychological therapy through the interaction between the painter, the painting work and the therapist, with the painting creation activity as the intermediary. The purpose is to develop symbolic language, touch the inner subconscious, and integrate into the personality, so as to produce cognitive and behavioral changes. Painting therapy and psychological analysis can improve the treatment compliance of children bone tumor patients, make psychological nursing and health education of patients more targeted, and promote the cooperation between medical care and patients.
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.
Spinal metastases account for 60% of all malignant bone metastases and represent a medically important treatment goal. For patients with malignant tumors diagnosed at this stage, performing En bloc spondylectomy with wide margin of resection facilitate the improvement in quality of life including ambulatory ability, daily activities independence and attenuation of bone pain. However, En bloc spondylectomy is a major operation with long operation time and frequent hemodynamic instability during the operation. Therefore, the anesthetic care plays an important role and an enhanced recovery after surgery (ERAS) is the goal. For the ERAS anesthesia protocol for En bloc spondylectomy, we propose two major components to achieve this goal: (1) an encephalographic spectrum guided multimodal anesthesia combined with ultrasound-guided nerve block and (2) the advanced machine-learning algorithm index, namely the hypotension predictive index (HPI) guided hemodynamic protocol.
To investigate, whether multi-fraction stereotactic body radiation therapy (SBRT) within 3 treatment fractions is non-inferior to the current standard of care of 5 fraction SBRT regarding pain response at 3 months after radiotherapy.
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.
