Filter by: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.
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
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.
