Filter by:The aim of the present study is to describe the course of functional recovery of patients with musculoskeletal tumours and undergone resection and reconstruction operations of lower limbs in the first six months post-surgery, differentiating them on the basis of the anatomical level involved.
In this observational study patients treated at European Institute of Oncology with radiotherapy to limbs will be included
Malignant tumor of bone is rare with poor prognosis. Surgery is the main treatment for non- metastatic bone tumor. Although neoadjuvant chemotherapy for non-metastatic bone tumor cannot improve survival rate based on adjuvant chemotherapy, it can reduce and clarify tumor boundary. Control of local recurrence rate is the core objective of oncotherapy. Surgery way and boundary have a significant effect on prognosis of non- metastatic bone tumor. Narlumosbartmab, a RANKL inhibitor, can make tumor boundary clear and reduce surgical difficulty by inhibiting osteoclast. This is a prospective, randomized, controlled, two-arm, open, single-center clinical trial to compare the efficacy and safety of narlumosbartmab combined with neoadjuvant chemotherapy and neoadjuvant chemotherapy alone in bone-derived malignancies with bone lytic lesions and multinucleated giant cells. Investigators mainly observe the local recurrence rate to evaluate the survival benefit for patients with poor prognosis.
Technologies 3D are demonstrating enormous potential for innovation in the field of surgery,introducing the concept of "treatment customization" (from planning surgery to implant design and manufacturing) on the patient's anatomy, simply by taking advantage of the patient's own common diagnostic images and the flexibility of 3D printing. In fact, this new construction technology allows the construction of the complex anatomical geometries with economy, simplicity and on scales of production unattainable by other traditional technologies.

The purpose of this non-randomized, prospective study is to assess the feasibility of planning and delivering conventional palliative radiotherapy to bone metastases on previously available diagnostic CT scans (dCT). Objectives:1) dosimetric accuracy of palliative radiotherapy designed on a dCT compared to a CT simulation 2) assess suitability of patient set up using surface landmarks and kilo voltage (kV) imaging 3) determine the proportion of patients who can receive radiotherapy designed on a dCT 4) confirm eligibility criteria for appropriate patients in clinical practice All enrolled patients will undergo a CT simulation with tattoos as per current standard of care.The radiation oncologist will place fields on the dCT and CT simulation. Radiotherapy will be planned on both CT scans and reviewed for quality by both the radiation oncologist and medical physicist.
This is a phase Ⅲ, multicenter, randomized, double-blind, study to evaluate the efficacy and safety of JMT103 in patients with bone metastases from malignant solid tumors. The purpose of this study is to determine if JMT103 is non-inferior to zoledronic acid.
This study aims to evaluate the osseointegration of 3D printed porous collars in hip and knee resection prostheses, in order to eliminate one of the causes of diaphyseal osteolysis, which often lead to loosening of the implants, and therefore to guarantee a further improvement in fixation of the implants in terms of both primary and secondary stability.
This study is looking at whether patients with cancer that has aggressively spread to the spine can be treated with stereotactic body radiation therapy only and avoid a large spine surgery
Background : Vertebral fracture is the most common complication of osteoporosis. Vertebroplasty is a widespread treatment modality for osteoporotic vertebral fractures, providing consolidation, rapid pain relief and preventing secondary vertebral collapse. Performing a biopsy at the same time as the operation does not lengthen the procedure or increase the risk of complications. The question therefore arises as to whether it is cost-effective diagnostically: are non-osteoporotic vertebral lesions detected when biopsies are taken? Methods: The investigators carried out a single-centre retrospective study at Nice University Hospital. From January 2016 to March 2022, 1729 biopsies were performed during 1439 vertebroplasty procedures on 1120 patients. The pre-operative laboratory work-up included a blood count, a C-reactive protein assay and a coagulation test. The imaging work-up systematically included MRI, unless contraindicated, in which case CT alone was performed. Vertebroplasty was performed in an interventional CT suite under dual CT and fluoroscopic guidance. The systematic biopsy sample was then sent to the anatomopathology department for analysis. Findings : The samples detected cancer in 35 patients, including 5 (0.44%) for whom the pre-operative work-up had not raised any suspicion. All the incidental findings were haemopathies, including 4 myelomas and one lymphoma. Conclusion : These results highlight the good performance of MRI in distinguishing osteoporotic vertebral fractures from solid tumour metastases. However, an exhaustive pre-operative work-up does not seem to be able to formally rule out an underlying malignant lesion. The investigators therefore recommend that biopsies be taken systematically when performing vertebroplasty.
The purpose of this clinical trial is to explore the impact of En bloc surgery and separation surgery combined with radiation therapy on the prognosis and survival of patients with spinal oligometastatic cancer, describe the clinical results, and optimize future treatment goals
