REVIEW
Chandra Diwakarla, Katherine Hannan, Nadine Hein, Desmond Yip
Pancreatic ductal adenocarcinoma is a devastating disease with a poor prognosis regardless of stage. To date the mainstay of therapy for advanced disease has been chemotherapy with little incremental improvements in outcome. Despite extensive research investigating new treatment options the current practices continue to utilise fluorouracil or gemcitabine containing combinations. The need for novel therapeutic approaches is mandated by the ongoing poor survival rates associated with this disease. One such approach may include manipulation of ribosome biogenesis and the nucleolar stress response, which has recently been applied to haematological malignancies such as lymphoma and prostate cancer with promising results...

Although potent androgen receptor pathway inhibitors (ARPI) improve overall survival of metastatic prostate cancer patients, treatment-induced neuroendocrine prostate cancer (t-NEPC) as a consequence of the selection pressures of ARPI is becoming a more common clinical issue. Improved understanding of the molecular biology of t-NEPC is essential for the development of new effective management approaches for t-NEPC. In this study, we identify a splice variant of the MYST/Esa1-associated factor 6 (MEAF6) gene, MEAF6-1, that is highly expressed in both t-NEPC tumor biopsies and neuroendocrine cell lines of prostate and lung cancers...

The differential diagnosis of benign and malignant changes in the prostate presents still definite difficulties; the antibody panel existing for these purposes is imperfect. Fatty acid synthase (FASN) is an androgen-regulated enzyme required for de novo lipogenesis. A number of studies have noted increased expression of the gene encoding this protein in tumors and precancerous lesions of different locations. AIM: Тo estimate the diagnostic value of analyzing the expression of FASN in prostate neoplasias...

Prostate cancer involving the anterior urethra is rare with few cases describing isolated recurrence to the anterior urethra. This case describes a patient with a history of metastatic prostate cancer who subsequently developed advanced prostate cancer involving the entire urethra with extension from the prostatic urethra to the urethral meatus. This will help future healthcare providers recognize this metastatic pattern as a possibility and explore this option when presented with a bleeding mass at the urethral meatus of unknown origin...

The E3 ubiquitin ligase adaptor speckle-type POZ protein (SPOP) is frequently dysregulated in prostate adenocarcinoma (PC), via either somatic mutations or mRNA downregulation, suggesting an important tumour suppressor function. To examine its physiologic role in the prostate epithelium in vivo, we generated mice with prostate-specific biallelic ablation of Spop. These mice exhibited increased prostate mass, prostate epithelial cell proliferation, and expression of c-MYC protein compared to littermate controls, and eventually developed prostatic intraepithelial neoplasia (PIN)...

BACKGROUND: Patients with previous malignancies could be at increased risk of non-small cell lung cancer (NSCLC). However, the extent of the risk is unknown for many cancer types; thus, it is unclear who might benefit from screening. MATERIALS AND METHODS: The Surveillance, Epidemiology, and End Results data set from 1992 to 2012 was used to identify patients with previous malignancies who received a diagnosis of NSCLC ≥ 6 months after their initial cancer diagnosis...

The aim of this study was to expand our knowledge about anticancer activity of some polyamine derivatives with quinoline or chromane as terminal moieties. Tested compounds were evaluated in vitro towards metastatic human prostate adenocarcinoma (PC3), human carcinoma (DU145) and mammary gland adenocarcinoma (MCF7) cell lines. Cell viability was estimated on the basis of mitochondrial metabolic activity using water-soluble tetrazolium WST1 to establish effective concentrations of the tested compounds under experimental conditions...

Current treatments for castration-resistant prostate cancer (CPRC) that target androgen receptor (AR) signaling improve patient survival, yet ultimately fail. Here we provide novel insights into treatment response for the anti-androgen abiraterone by analyses of a genetically-engineered mouse model (GEMM) with combined inactivation of Trp53 and Pten, which are frequently co-mutated in human CRPC. These NPp53 mice fail to respond to abiraterone, and display accelerated progression to tumors resembling treatment-related CRPC with neuroendocrine differentiation (CRPC-NE) in humans...

Dural prostate metastases (DPM) are a rare manifestation of metastatic prostate cancer seen in approximately one to six percent of cases. Presenting symptoms may include signs of elevated intracranial pressure, headache, altered mental status, or cranial nerve palsies. Hearing loss, sensory changes, dysarthria, and dysphagia are rare symptoms in DPM that were present in our patient. We present a case of a 58-year-old male with a known diagnosis of adenocarcinoma of the prostate presenting with symptoms of acute exacerbation of chronic obstructive pulmonary disease (COPD), sub-acute right-sided hearing loss, and right-sided facial paralysis...

Repair of DNA damage is critical for genomic stability, and DNA-dependent protein kinase (DNA-PK) has an important role in repairing double-strand breaks. We examined whether the DNA-PK activity of peripheral blood lymphocytes (PBLs) was related to biochemical (prostate-specific antigen: PSA) relapse and radiation toxicity in prostate cancer patients who have received radiotherapy. A total of 69 patients with localized adenocarcinoma of the prostate participated in this study. Peripheral blood was collected 2 years or later after radiotherapy and centrifuged, then DNA-PK activity was measured by a filter binding assay...

Radiotherapy is widely used in cancer treatment, however the benefits can be limited by radiation-induced damage to neighboring normal tissues. Parthenolide (PTL) exhibits anti-inflammatory and anti-tumor properties and selectively induces radiosensitivity in prostate cancer cell lines, while protecting primary prostate epithelial cell lines from radiation-induced damage. Low doses of radiation have also been shown to protect from subsequent high-dose-radiation-induced apoptosis as well as DNA damage. These properties of PTL and low-dose radiation could be used to improve radiotherapy by killing more tumor cells and less normal cells...

High-quality genomic analysis is critical for personalized pharmacotherapy in patients with cancer. Tumor-specific genomic alterations can be identified in cell-free DNA (cfDNA) from patient blood samples and can complement biopsies for real-time molecular monitoring of treatment, detection of recurrence, and tracking resistance. cfDNA can be especially useful when tumor tissue is unavailable or insufficient for testing. For blood-based genomic profiling, next-generation sequencing (NGS) and droplet digital PCR (ddPCR) have been successfully applied...

Prostate cancer is one of the most common cancers in men and a leading cause of cancer death worldwide, displaying a broad range of heterogeneity in terms of clinical and molecular behavior. Increasing evidence suggests that classifying prostate cancers into distinct molecular subtypes is critical to exploring the potential molecular variation underlying this heterogeneity and to better treat this cancer. In this study, the somatic mutation profiles of prostate cancer were downloaded from the TCGA database and used as the source nodes of the random walk with restart algorithm (RWRA) for generating smoothed mutation profiles in the STRING network...

This review focuses on histopathological aspects of carcinoma of the prostate. A tissue diagnosis of adenocarcinoma is often essential for establishing a diagnosis of prostate cancer, and the foundation for a tissue diagnosis is currently light microscopic examination of hematoxylin and eosin (H&E)-stained tissue sections. Markers detected by immunohistochemistry on tissue sections can support a diagnosis of adenocarcinoma that is primary in the prostate gland or metastatic. Histological variants of carcinoma of the prostate are important for diagnostic recognition of cancer or as clinicopathologic entities that have prognostic and/or therapeutic significance...

The rhodium(III)-catalyzed redox-neutral coupling reaction of N-acyl ketimines generated in situ from 3-hydroxyisoindolinones with various activated olefins is described. This approach leads to the synthesis of bioactive spiroisoindolinone derivatives in moderate to high yields. In the case of internal olefins such as maleimides, maleates, fumarates, and cinnamates, spiroindanes were obtained by the [3 + 2] annulations reaction. In sharp contrast, acrylates and quinones displayed the β-H elimination followed by Prins-type cyclization furnishing spiroindenes...

Prostate cancer is a common cancer in elderly men and it frequently metastasizes to regional lymph nodes and sometimes to bone. Very rarely in some of the cases it also shows involvement of non-regional lymph nodes like supra-diaphragmatic lymph nodes. In our report, we present a 60-year-old male, initially misdiagnosed as Chronic Obstructive Pulmonary Disease (COPD) with cervical lymph node involvement may be due to infective region or inflammatory pathology, which was later found to have prostatic adenocarcinoma metastatic to supraclavicular lymph nodes...

PURPOSE: Doublecortin and CaM kinase-like-1 (DCLK1) regulates microtubule polymerization in migrating neurons. Recently, DCLK1 has been reported to act as an intestinal tumor stem cell marker and has been shown to be expressed in cancer cells and in the stroma of breast, colon, pancreatic, and prostate cancers. Here, we studied DCLK1 expression in non-small cell lung cancer (NSCLC) by immunohistochemistry in association with clinicopathological factors and patient prognosis. METHODS: DCLK1 expression was analyzed by immunohistochemical staining of surgical specimens from 232 patients with pathological stage I NSCLC, including 187 adenocarcinomas...

REVIEW
Giovanni Branca, Antonio Ieni, Valeria Barresi, Giovanni Tuccari, Rosario Alberto Caruso
Cribriform is a histopathological term used to describe a neoplastic epithelial proliferation in the form of large nests perforated by many quite rounded different-sized spaces. This growth pattern may be seen in carcinomas arising in different organs, and shows important prognostic implications. Therefore, recent data in literature suggest that cribriform carcinoma is a histologically and clinically distinctive type of tumour that should be separated from other similar tumour types. In this article, the pathology of cribriform adenocarcinoma of the prostate, lung, breast, stomach, colon, thyroid, and skin is discussed with particular reference to morphologic and immunohistochemical features, differential diagnosis, and clinical behaviour...

BACKGROUND: The rate of incidental prostate adenocarcinoma (PCa) detection in radical cystoprostatectomy (RCP) varies widely, ranging from 15% to 54%. Such variability may be explained by institutional differences in prostate grossing protocols. Either partial or complete submission of the prostate gland in RCP may result in detection of clinically insignificant or significant incidental PCa. The aim of the study was to compare the clinical significance of PCa in RCP specimens in partial versus complete sampling...
