Multiple myeloma (MM) is a plasma cell neoplasm characterized by an abnormal proliferation of clonal, terminally differentiated B lymphocytes. Current approaches for the treatment of MM focus on developing new diagnostic techniques; however, the search for prognostic markers is also crucial. This enables the classification of patients into risk groups and, thus, the selection of the most optimal treatment method.

Article Synopsis
  • Merkel cell carcinomas of unknown primary (MCC-UPs) are deep tumors lacking an obvious skin tumor origin, raising questions about whether they are primary tumors in lymph nodes or spread from skin cancers.
  • A study analyzed the immune profiles and genetic characteristics of four groups of MCCs, focusing on differences between virus-positive and virus-negative tumors in both unknown and known primary cases.
  • The results showed that MCPyV-negative MCC-UPs have unique UV-signatures hinting at cutaneous origins, while MCPyV-positive tumors exhibit high immunogenicity, suggesting different underlying mechanisms for these cancers.

The fundamental role of major, minor and trace elements in different physiological and pathological processes occurring in living organism makes that elemental analysis of biomedical samples becomes more and more popular issue. The most often used tools for analysis of the elemental composition of biological samples include Flame and Graphite Furnace Atomic Absorption Spectroscopy (F-AAS and GF-AAS), Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Each of these techniques has many advantages and limitations that should be considered in the first stage of planning the measurement procedure.

Secondary immunodeficiency is observed in all patients with chronic lymphocytic leukemia (CLL) in varying degrees. The aim of the study was to review the available literature data on patients with CLL, with particular regard to the pathogenesis of the disease and the impact of humoral immunity deficiency on the clinical and therapeutic approach. A systematic literature review was carried out by two independent authors who searched PubMed databases for studies published up to January 2020.

Background: Specific genomic profile of cutaneous melanomas is related to UVR exposure, which exerts biological and therapeutic impact. Subungual melanoma (SUM) is an exceedingly rare disease; therefore, it is not well characterized. SUM pathogenesis is not related to UVR induced DNA damage and expected to differ from other melanoma subtypes.

Gastric cancer (GC) is one of the most commonly diagnosed malignancies and, unfortunately, still has a high mortality rate. Recent research points to CAR-T immunotherapy as a promising treatment for this disease. Using genetically engineered T cells designed to target a previously selected antigen, researchers are able to harness the natural anti-tumor activity of T cells.

Despite the significant progress of modern anticancer therapies, multiple myeloma (MM) is still incurable for the majority of patients. Following almost three decades of development, chimeric antigen receptor (CAR) T-cell therapy now has the opportunity to revolutionize the treatment landscape and meet the unmet clinical need. However, there are still several major hurdles to overcome.

Objective: We assessed the status of the V600E mutation in cell-free circulating tumor DNA (cfDNA) isolated from the plasma of patients with metastatic melanoma treated with the BRAF inhibitor vemurafenib, collected at different time points during therapy to evaluate the sensitivity and specificity of quantitative polymerase chain reaction and droplet digital polymerase chain reaction (ddPCR) and the correlation between the level of plasma cfDNA p.V600E and the long-term clinical outcome.

Methods: cfDNA in patients with -mutated melanoma ( = 62) was analyzed at baseline and at 4-8 weeks from the start of vemurafenib therapy.

Introduction: Histone deacetylase inhibitors (HDIs) are a group of compounds that exhibit anticancer activity, but their significance and usefulness in breast cancer (BC) treatment are still controversial. The ability of cancer cells to invade and migrate is augmented by the acquisition of a mesenchymal phenotype - a process known as epithelial-to-mesenchymal transition (EMT). Changes in the expression level of different cadherins, so-called cadherin switches, have been used to monitor the EMT process in development and tumor progression, in particular migration and invasion potential.

Double Posterior Descending Artery Arising from a Right Coronary Artery.

Int Heart J

September 2019

Department of Anatomy, Institute of Medical Sciences, Faculty of Medicine and Health Sciences, Jan Kochanowski University.

This paper presents two cases of human hearts (a 75-year-old woman and an 88-year-old man) with double posterior descending arteries (PDA) of various sizes originating from the right coronary artery, mainly supplying the interventricular septum as well as the posterior walls of both heart ventricles in a different scope. In the analysis of the arterial vasculature, a range of aspects were considered, such as the point of exit of the right coronary artery, the course of the vessel, the range of the blood supply of the interventricular septum and both ventricles, as well as selected morphometric parameters that were simultaneously compared with one another. These atypical changes presented based on the example of the analyzed cases will certainly constitute a valuable source of information for cardiac surgeons and interventional cardiologists in planning operations.

Department of Surgery and Surgical Nursery with a Research Laboratory and Genetic Laboratory, Faculty of Medicine and Health Sciences, Jan Kochanowski University, 19, 5-317 Kielce, Poland.

Background: It is postulated that both individual genotype and environmental factors such as diet may modify the risk of developing colorectal cancer (CRC). The influences of gene polymorphism and red meat intake on CRC occurrence in the Polish population were analyzed in this study.

Methods: Genotyping was performed with the qPCR method.

Four left renal arteries - a rare variant of kidney arterial supply.

Department of Anatomy, Institute of Medical Sciences, Faculty of Medicine and Health Sciences, Jan Kochanowski University, Kielce, Poland.

We describe the arterial supply of a human kidney harvested post-mortem from a 75-year-old female volunteer body donor. The kidney was analysed with con- trast-enhanced computed tomography (CT), and corrosion casting was used to reveal the kidney's angio-architecture. In the left kidney, we observed four renal arteries, each originating directly from the abdominal aorta.

Background: Explanation of the ultimate causes of acute and chronic pancreatitis is challenging. Hence, it is necessary to seek various etiological factors, including genetic mutations that may be of importance in triggering recurrence and progression of acute to chronic pancreatitis. The aim of this study was to determine the frequency of genetic mutations in patients with acute pancreatitis and to investigate their relationship with the etiology and clinical course.

Unlabelled: Second-line therapy options that improve survival for patients with advanced non-small-cell lung cancer (NSCLC) are needed. This randomized, phase II trial (n [ 143) investigated volasertib monotherapy or in combination with pemetrexed compared with pemetrexed monotherapy in patients with NSCLC whose disease had progressed after previous platinum-based chemotherapy. The combination of volasertib with pemetrexed did not improve efficacy compared with pemetrexed monotherapy.

Here we present the case of a 73-year-old woman with an ulcerated, advanced, hepatoid, and α-fetoprotein-producing poorly differentiated (G3) primary gastric adenocarcinoma pT3 N3a M1 with multinucleated cells and evident neuroendocrine component. This tumor was consistent with giant cell tumor type gastric carcinoma with osteoclast-like giant cells (OGCs). The cancer was HER2 and E-cadherin negative, chromogranin A dispersedly and moderately positive, and strongly α-fetoprotein-positive with evident CK AE1/AE3 immunoreactivity, while OGCs expressed CD68.
