D-Dimer as a Potential Prognostic Marker

Malignant tumors are often accompanied by increased risk for procoagulant activity, thrombosis and embolism. As a marker indicating such disturbancies is D-dimer, a product of fibrinolysis. In this retrospective study almost 300 patients with malignant tumors were evaluated. During LMWH treatment (as thromboprophylaxis) the highest frequency of VTE with worst prognosis occurred in pancreatic cancer (partly due to the late discovery) followed by ovarian, colonic and breast cancers. Also, increased D-dimer level correlated with progression (stages) and high mortality rate. Furthermore, D-dimer showed very similar or better prognostic activity than the clinically widely used classic tumor markers and suggested to use it as an additional value..     

mRNA expression, functional profiling and multivariate classification of colon biopsy specimen by cDNA overall glass microarray

INTRODUCTION mRNA expression array analysis is usually performed on high volume surgery or blood samples. However, evaluation of routine biopsy specimens could yield information, as to how the local pathological processes differ from healthy counterparts.…     

The First 5 Years of the Newest Eurotransplant Member State: Hungarian Results of International Organ Exchange From 2014 to 2018

IntroductionHungary joined Eurotransplant International (ET) to improve the chance of transplantation for Hungarian patients and patient outcomes, including access and graft and patient survival. After 5 years of full membership, the evaluation of numbers and quality indicators is possible.MethodA comparison was made between 5 years prior to a preliminary cooperation agreement (2007-2011) and 5 years after full ET membership (2014-2018). During the 2 study periods, we analyzed numbers and circumstances of deceased organ donors, multiorgan donors, donated organs, and transplantations in Hungary and development of waiting lists along with international organ exchanges.ResultThe number of actual organ donors increased by 22.09% (729 vs 890), an additional 823 organ removals represents an increase of 42.71% (1927 vs 2750). There were 46.51% more transplants managed in the selected periods (1561 vs 2287). The number of new patients on the waiting list increased (2305 vs 3247; 40.87%). The mean kidney mismatch number decreased from 3.21 to 2.96.ConclusionJoining ET has been an effective and efficient in terms of increasing access to organs and the lives of patients on the Hungarian waiting list posttransplant. It is also a benefit for patients with special needs because the number of organ transplants is greater than the increased number of donors.     

Progression of head and neck squamous cell cancer

Squamous cell cancer in the head and neck region (HNSC) is unique concerning its progression since it remains locoregional for long time and visceral metastases develop only in a later stage of the disease. Accordingly, molecular markers of the local invasion and the lymphatic dissemination both have critical importance. HNSC progression is associated with deregulated control of cell proliferation and apoptosis but it seems equally significant the disregulation of the proteolytic machineries. Here we outline the lymphatic metastatic cascade for HNSC to depict key molecular determinants as possible prognostic factors or therapeutic targets identifying immunological selection as a major feature. Unlike in local spreading, invasive potential of cancer cells seems to be less significant during lymphatic dissemination due to the anatomical properties of the lymphatic vessels and tissues. There is a general believe that HNSC is one disease however, data indicate that the anatomical localization of the tumor (the soil) such as oral, lingual, glottic or pharyngeal has a significant effect on the gene expression profile and corresponding biological behavior of HNSC. Furthermore, even the endocrine milieu of the host was proved to be influential in modulating the progression of HNSC. Gene expression profiling techniques combined with proteomics could help to define and select usefull genetic and biomarkers of progression of HNSC, some of them could well be potential novel therapeutic target.
