Brain metastasis is synchronous to the diagnosis of renal cell carcinoma (RCC). The prognosis of brain metastasis in RCC with the current treatment options is dismissal. Therefore, we present a case of an elderly female patient with RCC showing a partial response of brain metastasis after 18 months of 600 mg once daily sorafenib treatment who underwent right-sided nephrectomy. Further, withdrawal of sorafenib resulted in psychiatric changes along with increased metastasis lesions, which were recovered upon resuming the treatment, proposing that oral sorafenib can be used safely and efficiently for treatment of brain metastasis in advanced RCC.

Background: Reaching parenchymal segments of the lateral lenticulostriate artery (LSA) perforators, which represent the medial resection limit in insular gliomas (IG), remains a challenge. The currently described methods are indirect and sometimes, imprecise.
Methods: We report an antegrade direct skeletonization technique to identify these tiny arteries at the medial end of IGs with an illustrative case of grade 2 astrocytoma.

The manuscript conducts a comparative analysis to assess the impact of noise on medical images using a proposed threshold value estimation approach. It applies an innovative method for edge detection on images of varying complexity, considering different noise types and concentrations of noise. Five edges are evaluated on images with low, medium, and high detail levels.

Glutaminase controls the first step in glutaminolysis, impacting bioenergetics, biosynthesis and oxidative stress. Two isoenzymes exist in humans, GLS and GLS2. GLS is considered prooncogenic and overexpressed in many tumours, while GLS2 may act as prooncogenic or as a tumour suppressor.

Gliomas are the most common and lethal forms of malignant brain tumors. We attempted to identify the role of the aging-suppressor gene and Klotho protein in the immunopathogenesis of gliomas. We examined genetic variants by PCR-RFLP and measured serum Klotho levels using the ELISA method.

Glioblastoma (GB) is one of the most aggressive and treatment-resistant cancers due to its complex tumor microenvironment (TME). We previously showed that GB progression is dependent on the aberrant induction of chaperone-mediated autophagy (CMA) in pericytes (PCs), which promotes TME immunosuppression through the PC secretome. The secretion of extracellular matrix (ECM) proteins with anti-tumor (Lumican) and pro-tumoral (Osteopontin, OPN) properties was shown to be dependent on the regulation of GB-induced CMA in PCs.
