Stereotactic body radiation therapy (SBRT) also referred to as stereotactic ablative radiotherapy (SABR), is a technique which has emerged over the past two decades due to improvements in radiation technology. Unlike conventional external beam radiotherapy (cEBRT) which traditionally delivers radiation in small doses [approximately 2 Gray (Gy) per fraction] over several weeks, SBRT, typically delivered in one to eight fractions, is a technique whereby potentially ablative doses of radiotherapy (usually 7.5-20 Gy per fraction) can be delivered with steeper dose gradients and sub millimetre precision, minimising risk to surrounding normal tissues...

A Tomasian, T J Hillen, R O Chang, J W Jennings
BACKGROUND AND PURPOSE: Percutaneous radiofrequency ablation combined with vertebral augmentation has emerged as a minimally invasive treatment for patients with vertebral metastases who do not respond to or have contraindications to radiation therapy. The prevalence of posterior vertebral body metastases presents access and treatment challenges in the unique anatomy of the spine. The purpose of this study was to evaluate the safety and efficacy of simultaneous bipedicular radiofrequency ablation using articulating bipolar electrodes combined with vertebral augmentation for local tumor control of spinal metastases...

BACKGROUND: Bone is the most predominant site of distant metastasis in prostate cancer(PCa) and patients have limited therapeutic options at this stage. EXPERIMENTAL DESIGN: We performed a system-wide quantitative proteomic analysis of bone metastatic prostate tumors from 22 patients operated to relief spinal cord compression. At the time of surgery, most patients had relapsed after androgen-deprivation therapy, while 5 were previously untreated. An extended cohort of prostate cancer bone metastases (n=65) was used for immunohistochemical validation...

Circulating tumor cells (CTCs) are promising biomarkers in prostate cancer (PC) because they derive from primary tumor and metastatic tissues. In this study, we used quantitative real-time PCR (qPCR) to compare the expression profiles of 41 PC-related genes between paired CTC and spinal column metastasis samples from 22 PC patients that underwent surgery for spinal cord compression. We observed good concordance between the gene expression profiles in the CTC and metastasis samples in most of the PC patients...

Percutaneous image-guided ablation is used for treatment of both benign and malignant osseous lesions often leading to substantial pain relief and local tumor control. Paired with vertebral augmentation of the affected vertebra, patients can often become functional and experience significant pain reduction. However, bone ablation must be paired with various modalities of treatment as it only provides pain relief and local tumor control and does not address systemic metastatic disease. We describe a case of metastatic prostate cancer with epidural extension treated with percutaneous image-guided radiofrequency ablation and vertebral augmentation leading to substantial pain relief as well as resolution of the epidural disease as evidenced by short-term follow-up magnetic resonance imaging (MRI)...

RATIONALE: Benign metastasizing leiomyoma (BML) is rare condition involving distant metastases secondary to benign uterine leiomyoma, and it is most commonly found in the lungs. It rarely metastasizes to the spine to cause osteolytic damage and spinal canal compression. PATIENT CONCERNS: A 51-year-old woman with low back and bilateral leg pain and paresthesia was admitted to our ward. She has a previous medical history of uterine leiomyomas. Magnetic resonance imaging of the lumbar spine revealed vertebral body osteolytic destruction and soft tissue mass in the L4/5 with a secondary lumbar spinal stenosis...

BACKGROUND: Recently, molecule-targeting and bone-modifying agents have improved the treatment outcomes of lung cancer-derived metastatic spine tumors. Therefore, the prognostic factors for such tumors were examined, and novel scoring systems for predicting the life expectancy of patients with such tumors were proposed. METHODS: In 207 patients with lung cancer-derived metastatic spine tumors (surgery 49; conservative therapy 158), we retrospectively examined the factors that influenced the post-treatment survival time (age, sex, the affected site, pathology, general condition, the number of extraspinal bone metastases, the number of spinal metastases, the presence/absence of major internal organ metastasis, paralysis state, the total Tokuhashi score, the serum alkaline phosphatase level, the serum carcinoembryonic antigen level, molecule-targeting drug treatment, and bone-modifying agent treatment)...

An epidermoid cyst is a benign tumor, accounting for 0.2-1.8% of all brain tumors. Histologically, an epidermoid cyst has a wall consisting of squamous epithelium with keratinization and without skin components. An epidermoid cyst tends to develop in the cerebellopontine angle(CPA), middle cranial fossa, pituitary fossa, spinal cord, and other locations. We describe a rare case of malignant transformation of an epidermoid cyst with cerebrospinal fluid(CSF)dissemination. A 54-year-old man was referred to our hospital with chief complaints of dysesthesia of the right leg, persisting for 6 months, and dizziness and dysarthria for 2 months...

Objective: The incidence rate of thoracic metastasis from breast cancer is increasing. Microwave ablation is one type of clinical therapy used to treat metastatic spine disease, although it can cause protein denaturation and immediate cell death, and coagulative necrosis can occur. Minimally invasive open decompression is associated with lower rates of surgical complications in comparison to traditional open surgery. Therefore, it is an alternative therapeutic option for spinal metastases...
