Investigating the effects of PTEN mutations on cGAS-STING pathway in glioblastoma tumours.

Background: PTEN is a tumour suppressor gene and well-known for being frequently mutated in several cancer types. Loss of immunogenicity can also be attributed to PTEN loss, because of its role in establishing the tumour microenvironment. Therefore, this study aimed to represent the link between PTEN and cGAS-STING activity, a key mediator of inflammation, in tumour samples of glioblastoma patients.

Molecular dynamic simulation and functional analysis of pathogenic PTEN mutations in glioblastoma.

PTEN, a dual-phosphatase and scaffold protein, is one of the most commonly mutated tumour suppressor gene across various cancer types in human. The aim of this study therefore was to investigate the stability, structural and functional effects, and pathogenicity of 12 missense mutations (R15S, E18G, G36R, N49I, Y68H, I101T, C105F, D109N, V133I, C136Y, R173C and N276S) found by next generation sequencing of the gene in tissue samples obtained from glioblastoma patients. Computational tools and molecular dynamic simulation programs were used to identify the deleterious effects of these mutations.

Composite pheochromocytoma with spindle cell sarcoma - a rare tumor of the adrenal gland: case report.

Composite pheochromocytomas with a non-pheochromocytoma component stemming from an embryological origin other than the neural crest comprise a unique entity. We present a patient diagnosed with a composite pheochromocytoma with spindle cell sarcoma, which is, to our knowledge, the first case reported in the current literature. A 45-year-old female patient with elevated blood pressure had undergone adrenalectomy for clinically and radiologically diagnosed pheochromocytoma.

Two challenging cases of pituicytoma.

CASE 1: A 58-year-old female presented with decreased vision; she was admitted to the neurosurgery department of Ege University after the detection of a pituitary macroadenoma. Magnetic resonance imaging (MRI) showed a 28 * 18 * 17-mm suprasellar mass, and laboratory tests revealed hypopituitarism.

Diagnostic performance rates of the ACR-TIRADS and EU-TIRADS based on histopathological evidence.

Purpose: In this study, we aimed to assess the effectiveness of malignancy stratification algorithms of the American College of Radiology (ACR) and European Thyroid Association (ETA) in the delineation of thyroid nodules using a database of nodules that were unequivocally diagnosed by means of histopathological examination and meticulously matched with the imaged nodules.

Methods: A total of 165 patients having 251 thyroid nodules with histopathologically proven definitive diagnoses during a 5-year period were included in this study. All patients had preoperatively undergone ultrasonography (US) examination, and US characteristics of the thyroid nodules were retrospectively analyzed and assigned in compliance with the thyroid imaging reporting and data system categories recommended by the ACR (ACR-TIRADS) and ETA (EU-TIRADS).

The Correlation of Clinicopathological Findings and Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios in Papillary Thyroid Carcinoma.

Objectives: Inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been recently introduced as potential biomarkers for tumor pathogenesis, development and prognosis in solid tumors. Our aim was to assess the correlation of clinicopathological features and NLR and PLR in patients with papillary thyroid carcinoma (PTC).

Methods: A total of 201 papillary thyroid carcinoma patients were divided into groups with a cut-off preoperative median NLR and PLR value of 1,92 and 123.
