[INTRODUCTION - Authors present six cases of intramural oesophageal metastases of adenocarcinomas located in the gastro-oesophageal junction. The tumours and metastases were diagnosed by endoscopic examinations. PATIENTS AND METHODS - Between 01. 01. 1994. and 31. 12. 2000. a total number of 143 patients were examined with the diagnosis of adenocarcinoma of the gastro-oesophageal junction. In six patients (4,19 %), intramural oesophageal metastases were verified. In each case the diagnosis was confirmed by histological examination. TNM stage of the tumours was assessed considering the results of endoscopic ultrasound examination, the findings at initial operation and the pathological data in all cases, where resection was performed. The tumours were localized according to Siewert- Stein’s classification. RESULTS - In six patients who had adenocarcinoma of the gastro-oesophageal junction, the diagnosis of intramural oesophageal metastases was confirmed. The histological structure of the primaer tumours and metastases were the same. Metastases were detected by endoscopic ultrasound examination in three cases of the four examined patients as submucosal masses. All of the cardiac tumours proved to be well advanced: four of them classified as T4N1 by endoscopic ultrasound. Intramural metastases were diagnosed in each Siewert-Stein subgroups. CONCLUSION - Endoscopic examination is of crucial importance in the diagnosis of adenocarcinomas of the gastro-oesophageal junction and in their intramural metastases as well. Beside the endoscopic identification the primary tumour, the thorough examination of the proximal part of the oesophagus seems to be of great importance. These metastatic cancers appeared in the advanced stage of the disease. Endoscopic ultrasound examination is of great help in these cases to identify whether the mass causing oesophageal impression is outside of the wall of the organ, or in which layer it is localized. Endoscopic ultrasound examination also gives the possibility for preoperative assessment of the TNM stage of the disease.]

[Primary haemostasis in atherothrombotic processes]

UDVARDY Miklós

[It is now generally accepted, that the majority (>90%) of acute coronary and carotid syndromes are caused by thrombosis secondary to atheromatous plaque disruption, and approximately 75% of stroke cases are also of thrombotic origin. The prothrombotic changes in blood coagulation and in the primary haemostatic system may contribute substantially to the risk of occlusive arterial thrombotic events. The imbalance in the endothelium-platelet interaction seems to play crucial role in vessel wall response to injuries. Careful and complex analysis of platelet and clotting alterations may result in better understanding of arterial thrombotic processes and also in greater success of primary and secondary prevention by accelerating the development of better antithrombotic drugs.]

[Platelet aggregation inhibitors in the prevention of coronary coronary artery disease. „Handle with care!"]

NAGY Viktor

[Platelets play pivotal role in the pathophysiology of unstable angina, acute myocardial infarction and in complications following percutaneous coronary intervention. Three classes of platelet-inhibiting drugs, aspirin, thienopyridines and platelet glycoprotein IIb/IIIa inhibitors are now commonly used for the prevention and treatment of the disorders of coronary artery thrombosis. For the last several decades, aspirin has been the sole option for antiplatelet therapy in the treatment and prevention of the manifestations of cardiovascular disease. However, a wider selection of antiplatelet agents, including the thienopyridines (ticlopidine and clopidogrel) and the platelet glycoprotein IIb/IIIa receptor antagonists are available today. This review summarizes these drugs and scientific data that have led to their use in primary and secundary prevention, unstable angina, myocardial infarction and percutaneous coronary intervention.]

[Endo-sonographic anatomy of the ventricular system]

REISCH Róbert, RESCH Klaus, PERNECZKY Axel

[A preclinical cadaver study was performed to test a transendoscopic sonographic probe for neurosurgery. In 25 fresh post-mortem adult human cadaver with a total of 39 endo-sonographic dissections in the ventricular system were carried out. A sonograph with an outer diameter of 6 F was used and radial sonograms were made by a realtime image technique. First results showed precise imaging, comparable to a CT in a neighbouring area of 3 cm. In this publication, the authors describe the endo-neurosonographic anatomy of the ventricular system. The sonographic probe was advanced through the working canal of a ventriculoscope, then the endoscopic and sonographic imaging were compared. Results were documented by paralell sonographic and endoscopic photo and video recordings. Based on the authors experience, it is revealed that the additional sonographic view could also be used as a navigation tool.]

[Extracellular matrix of intracerebral tumors with different invasion activity]

KLEKNER Álmos, VARGA Imre, BOGNÁR László, HUTÓCZKI Gábor, KENYERES Annamária, TÓTH Judit, HANZÉLY Zoltán, SCHOLTZ Beáta

[Objectives - Ineffective surgical and radiotherapy of glioblastoma is mainly due to its intensive infiltrating behavior. Contrarily, brain metastases of anaplastic carcinomas are well-circumscribed intracerebral lesions that can be easily exstirpated in most cases. The molecules of the extracellular matrix (ECM) play a pivotal role in the peritumoral infiltration. In this study the mRNA expression of the ECM components was investigated in two types of intracerebral malignoma with different invasion activity. Our aim was to identify the ECM molecules that are responsible for the different intensity of peritumoral infiltration of tumors from different origin. Methods - The mRNA expression of twenty-three ECM molecules was determined by quantitative reverse transcriptase polymerase chain reaction. Four pieces of glioblastoma and four pieces of intracerebral lung adenocarcinoma metastasis from neurosurgical operation were investigated. Immunohistochemical investigations were performed in case of five molecules. Results - The mRNA expression of nine molecules (brevican, neurocan, neuroglycan-C, syndecan-1,2,4, tenascin-C, versican and matrix-metalloproteinase-[MMP]2) differed significantly by comparison of the two tumor types. By immunohistochemistry, neurocan, syndecan, versican and MMP-2 showed alteration in staining intensity according to the mRNA expression, while MMP-9 showed higher staining intensity in the metastatic tumor. Conclusions - The identified molecules can play an important role in the different infiltration activity of tumors from different origin. Thus these ECM-components could serve as targets for anti-invasion therapy in the future.]

FORRAI Gábor, BODOKY György

[Authors reviewed the recent results of pancreas tumour radiological diagnostics and the place of the imaging and interventional methods. Systematical review of the most recent articles were summarized (July 2003-December 2004) in the following subjects: the etiology and clinico-pathology, general diagnostic and therapeutical questions of early pancreatic neoplasms, abdominal ultrasound, computed tomography, multidetector computed tomography, magnetic resonance imaging, MR-cholangiopancreatography, endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, intraductal ultrasound, endoscopic ultrasound-guided cytology, percutaneous biopsy, positron emission tomography, positron emission tomography - computed tomography, special pancreatic tumours. Experiences about the pancreas diagnostic methods are accumulating year-to-year rapidly. Therefore the current examination algorithm is changing continuously. New diagnostic and therapeutic modalities are entering in the daily practice. These are the reasons why the up-to-date knowledge of the literature is mandatory.]

[Systemic adjuvant pharmacotherapy of colorectal cancer]

BODOKY György

[Colorectal cancer is one of the most frequent cancer in the postindustrial world; its most common form is adenocarcinoma. In Hungary, colorectal cancer has the second highest mortality among tumours. If diagnosed early, it might be successfully treated by surgery, however, chemotherapy is necessary to prevent tumor relapse and development of metastases and achieve adequate palliation. In the past few years, adjuvant treatment of colorectal cancer has improved substantially. Many new drugs have been developed, which are also being used in combination with previously known agents. This article will discuss the novelties in the field of adjuvant chemotherapy for colorectal cancer and the main guidelines of adjuvant treatment.]

[MANAGEMENT OF GASTROINTESTINAL DISEASES DURING PREGNANCY]

NOVÁK János, TAKÁCS Tamás, ÚJSZÁSZY László, BENE László, OLÁH Attila, RÁCZ István

[Medical treatment of gastrointestinal diseases has developed dramatically in the past 10 years. However, management of gastrointestinal disorders in pregnancy is still a serious challenge and requires special expertise. This paper provides recommendations on the indications of gastrointestinal endoscopy and treatment options based on the best available evidence, primarily from large retrospective studies and case reports. Currently there are no generally applicable, widely accepted, evidence-based guidelines available on the treatment of pregnant women. The risks of the gastrointestinal disease versus those of the medications used to treat it should be considered with regard to the health of both the mother and the foetus in each individual case. The risks and benefits of treatment and the consequences of withholding treatment should be discussed with the patient, the obstetrician and any other clinicians involved, and should be carefully documented.]
