Microwave ablation combined with cementoplasty under real-time temperature monitoring in the treatment of 82 patients with recurrent spinal metastases after radiotherapy.

BackgroundThe spine is the most frequently affected part of the skeletal system to metastatic tumors. External radiotherapy is considered the first-line standard of care for these patients with spine metastases. Recurrent spinal metastases after radiotherapy cannot be treated with further radiotherapy within a short period of time, making treatment difficult. We aimed to evaluate the effectiveness and safety of MWA combined with cementoplasty in the treatment of spinal metastases after radiotherapy under real-time temperature monitoring.MethodsIn this retrospective study, 82 patients with 115

Treatment of pathologic spinal fractures with combined radiofrequency ablation and balloon kyphoplasty.

BACKGROUND: In oncologic patients with metastatic spinal disease, the ideal treatment should be well tolerated, relieve the pain, and preserve or restore the neurological function.The combination of fluoroscopic guided radiofrequency ablation (RFA) and kyphoplasty may fulfill these criteria. METHODS: We describe three pathological vertebral fractures treated with a combination of fluoroscopic guided RFA and kyphoplasty in one session: a 62-year-old man suffering from a painful L4 pathological fracture due to a plasmocytoma, a 68-year-old man with a T12 pathological fracture from metastatic he

Minimally Invasive Surgical Techniques for Management of Painful Metastatic and Primary Spinal Tumors.

Patients with metastatic spinal disease are affected by disabling pain. The treatment of spinal metastases is focused on pain reduction and improvement in quality of life. Until recently, many patients with metastatic spinal disease did not qualify as surgical candidates due to the risks of surgery and length of recovery period. However, recent advances in minimally invasive surgery such as kyphoplasty and vertebroplasty allow patients to safely undergo surgery for pain relief with a short recovery period. The studies reviewed here suggest that vertebral augmentation is successful in reducing

Neurotropin alleviates rat osteocarcinoma pain via P2X3 receptor activation in the midbrain periaqueductal gray.

ObjectivesClinically effective analgesia treatment for patients afflicted with osteocarcinoma lessens the intensity of pain. The midbrain periaqueductal gray (PAG) plays a critical role in pain modulation, and activation of P2X3 receptors in this region mediates pain processing. Neurotropin is a small molecule drug used for analgesic treatment of a number of chronic pain conditions. The present study aims at determining whether P2X3 receptor activation in PAG is responsible for the analgesic effect of neurotropin in rats with osteocarcinoma pain.Materials and methodsThe tibia of female Sprague

Surgical Approach and Laser Applications in BRONJ Osteoporotic and Cancer Patients.

Bisphosphonates-related Osteonecrosis of the Jaw (BRONJ) has been reported with increasing frequency in literature over last years, but its therapy is still a dilemma. One hundred ninety patients affected by BRONJ were observed between January 2004 and November 2011 and 166 treated sites were subdivided in five groups on the basis of the therapeutical approach (medical or surgical, traditional or laser-assisted approach, with or without Low Level Laser Therapy (LLLT)). Clinical success has been defined for each treatment performed as clinical improvement or complete mucosal healing. Combinatio

Case Report: Abblation как новая х терапия в режиме слабого гематологического расстройства с внематологическими повреждениями.

Гематологические заболевания как категория злокачественных опухолей, происходящих из гематопоиетической системы, давно полагаются на такие виды лечения, как химиотерапия, радиотерапия и трансплантация стволовых клеток. Вместе с тем по-прежнему сохраняются проблемы, связанные с устранением местных прогрессивных повреждений, рецидивов/обезболивающих повреждений и участием специальных анатомических объектов, особенно в недееспособности. Технология абляции, которая представляет собой минимально инвазивный метод лечения на местном уровне, непосредственно уничтожает поврежденные ткани с помощью физи

Comparison of treatment options with long intramedullary nail and dynamic hip screws for metastatic subtrochanteric fracture: A cohort study.

BACKGROUND: Pathological subtrochanteric fractures pose challenges due to the high biomechanical demands of this region and the systemic complexity of metastatic disease. At present, the optimal fixation method remains controversial, particularly between intramedullary nailing (IMN) and dynamic hip screw (DHS) fixation. This study compared the mechanical, oncological, and functional outcomes of these two treatment strategies. METHODS: This retrospective study reviewed patients treated for metastatic subtrochanteric fractures at a single tertiary referral center between 2002 and 2018. Demograp

Surgery of the tumors of the spine.

Spinal tumors encompass a heterogeneous group of primary and metastatic lesions requiring individualized management strategies based on tumor biology, patient prognosis, and mechanical stability. Decision-making frameworks, such as NOMS, SINS, and Tokuhashi score, provide structured guidance for selecting metastatic patients for surgery and defining individualized treatment strategies. En bloc resection remains the gold standard for selected primary malignant tumors, whereas separation surgery combined with stereotactic radiosurgery represents the cornerstone of modern metastatic spine disease

From Nanoparticles to Cancer Nanomedicine: Old Problems with New Solutions.

Anticancer nanomedicines have been studied over 30 years, but fewer than 10 formulations have been approved for clinical therapy today. Despite abundant options of anticancer drugs, it remains challenging to have agents specifically target cancer cells while reducing collateral toxicity to healthy tissue. Nanocompartments that can be selective toward points deeply within malignant tissues are a promising concept, but the heterogeneity of tumor tissue, inefficiency of cargo loading and releasing, and low uniformity of manufacture required from preclinical to commercialization are major obstacle

Radiofrequency Ablation in Vertebral Body Metastasis with and without Percutaneous Cement Augmentation: A Systematic Review Addressing the Need for SPINE Stability Evaluation.

Vertebral body metastases (VBM) are one of the most frequent sites of bone metastasis, and their adequate therapeutic management still represents an insidious challenge for both oncologists and surgeons. A possible alternative treatment for VBM is radiofrequency ablation (RFA), a percutaneous technique in which an alternating current is delivered to the tumor lesion producing local heating and consequent necrosis. However, RFA alone could alter the biomechanics and microanatomy of the vertebral body, thus increasing the risk of post-procedure vertebral fractures and spine instability, and inde

Cold Atmospheric Plasma in the Treatment of Osteosarcoma.

Human osteosarcoma (OS) is the most common primary malignant bone tumor occurring most commonly in adolescents and young adults. Major improvements in disease-free survival have been achieved by implementing a combination therapy consisting of radical surgical resection of the tumor and systemic multi-agent chemotherapy. However, long-term survival remains poor, so novel targeted therapies to improve outcomes for patients with osteosarcoma remains an area of active research. This includes immunotherapy, photodynamic therapy, or treatment with nanoparticles. Cold atmospheric plasma (CAP), a hig

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives.

Immunotherapy has achieved remarkable clinical success in certain cancers, particularly through adoptive cell therapy (ACT), where T cell engineering with chimeric antigen receptor (CAR) has driven major clinical breakthroughs in the treatment of hematologic malignancies. However, efficacy against solid tumors remains limited due to multiple barriers, including the scarcity of tumor-specific antigens, antigen heterogeneity, immunosuppressive tumor microenvironment, and physical obstruction of T cell infiltration by dense extracellular matrix. Nanoparticle (NP)-based approaches can overcome the
