INTRODUCTION: Currently used tools for breast cancer prognostication and prediction may not adequately reflect a young patient's prognosis or likely treatment benefit because they were not adequately validated in young patients. Since breast cancers diagnosed at a young age are considered prognostically unfavourable, many treatment guidelines recommend adjuvant systemic treatment for all young patients. Patients cured by locoregional treatment alone are, therefore, overtreated. Lack of prognosticators for young breast cancer patients represents an unmet medical need and has led to the initiation of the PAtients with bReAst cancer DIaGnosed preMenopausally (PARADIGM) initiative...

Programmed death ligand 1 (PD-L1) expression is a predictive biomarker of the success of PD-1/PD-L1 inhibitor therapy for patients with advanced non-small cell lung cancer (NSCLC) but its role as a prognostic marker for early stage resectable NSCLC remains unclear. Here, we studied PD-L1 expression and tumor infiltrating lymphocytes (TILs) in surgically resectable NSCLC and correlate the finding with clinicopathological features and patient outcomes. Total of 170 archival samples of resectable NSCLC were probed for PD-L1 expression using the clone 22C3 pharmDx kit...

BACKGROUND: Equine ocular diseases pose a medical challenge due to long-lasting and cost-consuming therapies as well as economic issues associated with potential decrease in value of affected horses. The scale of the problem is significant but difficult to precisely define because epidemiological data is limited and lacks consistency in presentation. To date, no retrospective studies specifically investigating Arabian horses have been published. RESULTS: The aim of this cross-sectional study was to investigate the prevalence of ocular lesions and define the ocular diseases present in Arabian horses from breeding farms in Poland...

BACKGROUND: Although metastatic disease is commonly seen in high grade carcinomas of gynecologic origin, it also occurs in low to intermediate grade endometrioid carcinomas (LGEMCAs), and may even be the primary presentation of disease. Tissue confirmation is necessary to guide therapy, but performing biopsies might not always be feasible or practical. In such instances, fine needle aspiration (FNA) is a safe and efficient alternative. No comprehensive series describing the cytomorphologic features of metastatic LGEMCA on FNA samples has been published...

Metastatic tumors to the breast are rare but constitute a major diagnostic dilemma. Of these, non-mammary carcinomatous metastases to the breast are particularly challenging and, without a clinical history, may be extremely difficult to distinguish from primary breast carcinoma (PBC). We specifically studied metastatic tumors of pulmonary origin, as the lung is one of the major primary sites for carcinomatous metastasis to breast. Sixteen metastatic lung tumors to the breast were identified in our archives between 1996 and 2017 including 12 non-small cell lung carcinomas (NSCLC), one large-cell neuroendocrine, one atypical carcinoid, and two small-cell carcinomas...

Pseudomyogenic hemangioendothelioma (PHE) is an uncommon neoplasm with propensity for local recurrence. The tumor mimics epithelioid hemangioendothelioma and epithelioid sarcoma, representing a possible diagnostic pitfall. We investigated the clinicopathological, immunohistochemical and fluorescence in situ hybridization features of PHEs. Eight cases of PHE were retrieved from our pathology archives. The clinical and outcome information was available in six patients. In six cases the tumors were located in the lower limb while the upper limb was involved in two cases...

Infantile fibrosarcoma and congenital mesoblastic nephroma are tumors of infancy traditionally associated with the ETV6-NTRK3 gene fusion. However, a number of case reports have identified variant fusions in these tumors. In order to assess the frequency of variant NTRK3 fusions, and in particular whether the recently identified EML4-NTRK3 fusion is recurrent, 63 archival cases of infantile fibrosarcoma, congenital mesoblastic nephroma, mammary analog secretory carcinoma and secretory breast carcinoma (tumor types that are known to carry recurrent ETV6-NTRK3 fusions) were tested with NTRK3 break-apart FISH, EML4-NTRK3 dual fusion FISH, and targeted RNA sequencing...

Tissue-based cancer studies can generate large amounts of histology data in the form of glass slides. These slides contain important diagnostic, prognostic, and biological information and can be digitized into expansive and high-resolution whole-slide images using slide-scanning devices. Effectively utilizing digital pathology data in cancer research requires the ability to manage, visualize, share, and perform quantitative analysis on these large amounts of image data, tasks that are often complex and difficult for investigators with the current state of commercial digital pathology software...

Adaptations to stress can occur through epigenetic processes and may be a conduit for informing offspring of environmental challenge. We employed ChIP-sequencing for H3K4me3 to examine effects of early maternal deprivation (peer-rearing, PR) in archived rhesus macaque hippocampal samples (male, n = 13). Focusing on genes with roles in stress response and behavior, we assessed the effects of rearing on H3K4me3 binding by ANOVA. We found decreased H3K4me3 binding at genes critical to behavioral stress response, the most robust being the oxytocin receptor gene OXTR, for which we observed a corresponding decrease in RNA expression...

Clear cell carcinoma (CCC) is a low-grade malignancy that commonly arises in minor salivary glands of the oropharynx and other sites. EWSR1-ATF1 gene fusions seem to be specific for this salivary neoplasm. Testing for EWSR1-ATF1 has expanded the histologic spectrum of CCC. As one important example, many CCCs have a predominantly squamous phenotype with few clear cells, a finding that can cause confusion with squamous cell carcinoma (SqCC). P16 immunohistochemical staining to determine human papillomavirus (HPV) status has become standard practice for all oropharyngeal carcinomas showing squamous differentiation...

BACKGROUND: Multiple oncogenic viruses including, mouse mammary tumor virus, bovine leukemia virus, human papilloma virus, and Epstein Barr virus, have been identified as separate infectious pathogens in human breast cancer. Here we demonstrate that these four viruses may be present in normal and benign breast tissues 1 to 11 years before the development of same virus breast cancer in the same patients. METHODS: We combined the data we developed during investigations of the individual four oncogenic viruses and breast cancer...

PURPOSE: Due to the fact that the internal carotid artery (ICA) is responsible for nourishing two thirds of the brain volume, our aim was to inspect the morphofunctional consequences of the bilateral lack of this artery. METHODS: In order to examine this condition, we referred to both the library archive of our Faculty of Medicine and electronic databases of anatomical and clinical reports that included the following keywords: "absence," "aplasia," or "agenesis" in combination with "internal carotid artery," "common carotid artery," or only "carotid artery...

BACKGROUND: The incidence of thyroid cancer is increasing worldwide, and there is an emerging need to develop accurate tools for diagnosis. Fine needle aspiration biopsy has greatly improved evaluation of thyroid nodules, but challenges with indeterminate lesions remain in up to 25% of biopsies. Novel tissue biomarkers may assist in improved nodule characterization. Microcalcifications occurring in thyroid cancers suggest proteins involved in bone formation may play a role in thyroid carcinogenesis...

STUDY DESIGN: A cross-sectional MR imaging study. OBJECTIVE: To classify and characterize endplate defects using routine lumbar MR images, and to determine associations of endplate defects with Modic Changes (MCs) and disc degeneration. SUMMARY OF BACKGROUND DATA: Previously, a cadaveric study revealed that endplate lesions were common and associated with back pain history. New in vivo approaches appropriate for clinical studies are needed to further this potentially important line of research on the clinical significance of endplate lesions, including their relation with MCs, disc degeneration and back pain...

Objectives The bronchial lumen to pulmonary artery (BA) ratio is utilized to evaluate pulmonary pathology on CT images. The BA ratio may be unreliable when changes are present in bronchial and pulmonary arteries concurrently. Bronchial lumen to vertebral body (BV) and pulmonary artery to vertebral body (AV) ratios have been established in normal cats and may serve as an alternative. This study aimed to evaluate the BV, AV and BA ratios in cats before and after infection with Dirofilaria immitis, with and without selamectin administration, and to characterize the distribution of disease...

Background: The diagnosis of glomerular diseases is based on the evaluation of histological lesions in renal tissue by means of light and electronic microscopy, and immunofluorescence technique. Frozen and archival formalin-fixed paraffin-embedded kidney biopsies represent a stored resource for high-throughput technologies. Transcriptomics makes it possible to study the whole gene-expression profile of cells and tissues in a specific period and/or condition. The results, whether considered alone or integrated with other omics data, could help to improve existing knowledge about the pathogenetic mechanisms of glomerulopathies...

OBJECTIVE: Autofluorescence induced interference is one of the major drawbacks in immunofluorescence analysis of formalin-fixed paraffin-embedded tissues, as it decreases the signal-to-noise ratio of specific labeling. Apart from aldehyde-fixation induced artifacts; collagen and elastin, red blood cells and endogenous fluorescent pigment lipofuscin are prime sources of autofluorescence in vascular and aging tissues. We describe herein, an optimized indirect-immunofluorescence method for archival formalin-fixed paraffin-embedded tissues tissues and cryo sections, using a combination of 3-reagents in a specific order, to achieve optimal fluorescence signals and imaging...
