Morphological and functional alterations of the prostate tissue during clinical progression in hormonally-na ïve, hormonally-treated and castration-resistant patients with metastatic prostate cancer.

Morphological and functional alterations of the prostate tissue during clinical progression in hormonally-naïve, hormonally-treated and castration-resistant patients with metastatic prostate cancer. Oncol Lett. 2020 Nov;20(5):201 Authors: Korček M, Sekerešová M, Makarevich AV, Gavurová H, Olexíková L, Pivko J, Barreto L Abstract Since commony used tools in oncological practice for the diagnosis of castration-resistent prostatic acinar adenocarcinoma are based on clinical criteria, such as castrate testosterone level, continuous rise in serum prostate-specific antigen, progression of preexisting disease or appearance of new metastases, it is important to identify reliable histopathological markers for the identification of this disease. Therefore, the aim of the present study was to determine the association between results from histological analysis, ultrastructural analysis and apoptosis in the prostate of patients with metastatic acinar prostatic adenocarcinoma (mPC). Patients were treated with androgen deprivation therapy (ADT), abiraterone acetate (Abi) therapy or received no treatment. Prostate tissue samples were divided into four groups as follows: i) Group 1, tissues from patients with benign prostatic hyperplasia (adenocarcinoma negative); ii) group 2, tissues from patients with metastatic hormone naïve prostate cancer; iii) group 3, tissues from patients with mPC treated with ADT; and iv) group 4, ti...

AbstractThe differential diagnosis of abnormalities in the prostate is broad, covering common (acinar adenocarcinoma, benign prostatic hyperplasia, chronic prostatitis, hemorrhage, cysts, calcifications, atrophy and fibrosis) and less common conditions (tumors other than acinar adenocarcinoma, granulomatous prostatitis containing tuberculosis, abscesses and other conditions, and idiopathic disorders such as amyloidosis and exophytic benign prostatic hyperplasia). Recent advances in magnetic resonance imaging (MRI) of the prostate gland and imaging guidelines, such as the Prostate Imaging Reporting and Data System version 2...

CIP2A expression in high grade prostatic intraepithelial neoplasia and prostate adenocarcinoma: a tissue mıcroarray study. Malays J Pathol. 2020 Aug;42(2):227-236 Authors: Celikden SG, Baspinar S, Ozturk SA, Karaibrahimoglu A Abstract INTRODUCTION: CIP2A is an oncoprotein involved in the progression of several human malignancies. It has recently been described as a prognostic marker in many cancers. The present study aimed to investigate the immunohistochemical expression of CIP2A in benign prostatic hyperplasia (BPH), high grade prostatic intraepithelial neoplasia (HGPIN) and prostate cancer (PC), an...

Authors: Janiczek M, Szylberg Ł, Antosik P, Kasperska A, Marszałek A Abstract Prostate cancer (PCa) is the second most commonly diagnosed malignant tumor and the fifth leading cause of cancer death in men in the world. The most common types of tumors are adenocarcinomas. Prostate cancer is a slow-growing cancer. The incidence increases with age. Evaluation of proinflammatory factors such as IL-17A, IL-17F, IL-17RA, and IL-17RC expression makes it possible to assess the impact of inflammatory process on progression of PCa. The aim of the study was to retrospectively assess the histological material of PCa divided ...

This study aimed at identifying the cell type/s, if any, expressing PDE5 in human healthy or pathological prostate sections in order to further validate the rationale of PDE5 inhibitor (PDE5i) treatment of benign prostatic hyperplasia (BPH) and their safety in the treatment of erectile dysfunction following prostate cancer (PCa) surgery.Materials and methodsBy immunohistochemical analysis, we studied PDE5 expression in tissue microarrays containing sections obtained from healthy, BPH, and PCa samples.ResultsOur results showed that PDE5 is barely expressed in the epithelial or stromal compartment of normal human prostates, ...

This study is an important step forward in highlighting C1q as a new prognostic candidate biomarker for a range of carcinomas. Methods Oncomine Database Analysis The expression levels of C1QA, C1QB, and C1QC genes in various carcinomas were analyzed using Oncomine (, a cancer microarray database and web-based data mining platform from genome-wide expression analyses (22, 23). We compared the differences in mRNA level between normal tissue and carcinoma. The mRNA expression levels in neoplastic tissues compared to the healthy tissues were obtained as the parameters of p-value 2, and gene ranking in the t...

CONCLUSIONS: Expression of miR-301a could be a valuable adjunct tool for stratifying patients with elevated prostate-specific antigen, as well as those diagnosed with CaP. Including the miR-301a as an additional variable in MSKCC post-prostatectomy nomogram improved its ability in facilitating clinical decision-making. PMID: 30195463 [PubMed - as supplied by publisher]

Abstract Oxidative stress is a primary cause of vascular endothelial damage. In the prostate, ischemia increases the levels of reactive oxygen species, growth factors and cytokines, and induces the development of angiogenesis, which results in cancer progression. The expression levels of an oxidative stress marker, 8-hydroxyguanosine (8-OHdG), were compared between prostate cancer and non-neoplastic prostate tissues. A prostate tissue microarray composed of 10 cases of prostatic adenocarcinoma and 70 cases of benign prostatic hyperplasia was immunohistochemically stained for 8-OHdG. All cases expressed 8-OHdG. The...
