Purpose: The aim of this study was to provide some useful insights into the clinical and imaging presentations, treatment and prognostic factors in patients with neurological deficit caused by clear cell renal cell carcinoma (CCRCC) spinal metastases for the sake of designing individualized therapeutic plans for such patients.
Methods: A total of 30 patients with neurological deficit due to CCRCC spinal metastases who received surgery in our department were identified during an 8-year period from 2003 to 2012 and used for discussion of treatment options for CCRCC spinal metastases on the basis of literature review and our own experience.
Results: Univariate analysis showed that age (≤45 years/>45 years), visceral metastasis, Tomita score (3-5/6-8), Tokuhashi score (4-9/10-12) and radiotherapy were suggested as the potential prognostic factors. However, the multivariate Cox regression model showed that only Tokuhashi score was an independent prognostic factor.
Conclusions: Tokuhashi score 10 or more is a favorable prognostic factor of CCRCC spinal metastasis.

Background: The Spinal Instability Neoplastic Score (SINS) is used in determining instability in patients with spinal metastases. Intermediate scores of 7 to 12 suggest possible instability, but there are no clear guidelines to address patients with these scores.
Methods: We searched in PubMed, EMBASE, and Cochrane databases for studies that included patient demographics, tumor histology, surgical or radiotherapy management, and outcomes of patients with intermediate SINS.

Objective: This review aims to formulate the most current, evidence-based recommendations regarding radiation therapy, radiosurgery, and chemotherapy for patients with metastatic spine tumors.
Methods: A systematic literature using PRISMA methodology was performed from 2010-2023 using the search terms "radiosurgery," "radiation therapy," "external beam radiation therapy," or "stereotactic body radiation therapy" in conjunction with "spinal," "spine," "metastasis," "metastases," or "metastatic."
Results: Spinal metastases should be managed in a multidisciplinary team consisting of spine surgeons, radiation oncologists, radiologists and oncologists.

(1) Background: Testicular cancer, although accounting for only 0.5% to 1% of all solid male cancers, is the most common malignancy in males aged 15 to 35 years. Non-seminomatous germ cell tumors (NSGCT) represent nearly half of all testicular germ cell tumors and are associated with a more aggressive clinical course.
