[The frequency of colorectal cancer is increasing all over the world. It is the second most frequent oncological disease leading to death in both sexes in Hungary. The main part of colorectal cancer develope after the age of 50. In case of patients having higher risk we have to calculate with the earlier appearance of the tumour and detectable molecular genetic disorders. The development of colorectal cancer needs a long time. Before the appearance of the cancer, precancerous processes (adenomas, polyps) can be detected in the large intestine. The development of colorectal cancer can be prevented by the removal of the adenomas (polypectomy). There are many different and efficient methods to detect the precancerous and early disorders. For increasing the compliance to screening programs the common efforts of the society, the National Health Care Services and medical doctors are necessary. The education of the population and the medical services would also be helpful. The colorectal cancer screening programs are costeffective and supported by the different health services independently from the type of the insurance. Screening the patients having higher risk is one of most important task. In these cases the use of colonoscopy is the most frequent method for the screening and follow up as well.]

[NEUROFIBROMATOSIS, MALIGNANT MELANOMA AND HYPERTHYREOIDISM IN A HCV POSITIVE PATIENT]

FOLHOFFER Anikó, HORVÁTH Andrea, CSÁK Tímea, NÉBENFÜHRER László, TELKES Márta, IVÁNYI András, SZALAY Ferenc

[INTRODUCTION - Similar occirrence of neurofibromatosis and malignant melanoma is rare. We report a patient with neurofibromatosis, cutaneous melanoma, hyperthyreoidism and HCV positivity. CASE REPORT - A 43-year-old woman has been under care for neurofibromatosis for 16 years when she presented with increased serum ?- glutamyltransferase, alkaline phosphatase activity and anti-HCV antibody positivity at regular checkup. A pigmented lesion removed from her back histologically proved to be cutan melanoma. Interferon treatment was applied. She lost 8 kilograms in half a year which was caused not by the tumor progression, but hyperthyreoidism. A rapid clinical and laboratory improvement was observed for thyreostatic treatment and she regained her bodyweight. One year later she presented with a cough caused by pulmonary tumor. The tumor was surgically removed and histologically diagnosed as metastasis of melanoma. Cytostatic treatment was applied and she became asymptomatic. Four years after the diagnosis of melanoma she died of apoplexy. During the autopsy there was no sign of either melanoma or liver disease. CONCLUSIONS - The careful investigation of skin should be emphasised even in case of long established neurofibromatosis. The presented case shows an association of malignant melanoma and neurofibromatosis. In the background of loss of bodyweight even in a patient with history of malignant disease other causes should also be searched such as hyperthyreoidism especially during interferon therapy.]

[CURRENT STATUS OF THE DIAGNOSTICS AND THERAPY OF UROLOGICAL TUMOURS]

ROMICS Imre

[Significant amount of urological patients have malignant disease. Prostate cancer is the second most frequent cancer in males associated with high mortality and decreased quality of life. Hence the importance of early diagnosis. Furthermore, diagnostical protocols, operative and conservative therapeutic modalities are summarised. Hematuria is the most frequent sign of bladder cancer. Diagnostical, surgical and adjuvant therapeutical differencies of the superficial and muscle invasive bladder cancers are discussed. The urinary deviation after cystectomy could be associated with complications therefore regular follow up of patients is necessary. The standard therapy of renal cancer is surgical. Unfortunately its mortality has not change during past years. Testicular cancer is the disease of young males. If diagnosed early, most cases are curable. Therapy is complex, involving surgical, chemoand radiation therapy as well. Penis cancer is a rare disease, but highly malignant. In advanced stage patients are incurable.]

[Experiences about the breast diagnostic methods are accumulating year-to-year, rapidly. Therefore the current examination algorithm is changing continuously. New diagnostic and therapeutic modalities are entering into the daily practice. Some of them became obsolete, so far their application is becoming a faulty decision. Some other methods become obligatory steps in the diagnostics. These are the reasons why the up-to-date knowledge of the literature is mandatory. Systematic review of the most recent articles of the last two years (January 2005-December 2006) of breast radiological diagnostics and the actual place of the imaging and interventional methods are presented. The following topics are summarized: breast cancer screening with conventional and digital mammography, computer assisted diagnostics (CAD), high risk patients' screening, US, MRI, MSCT, PET/CT, diagnostic interventions, differential diagnostics, percutaneous tumour ablation, therapy-related questions in the diagnostic work up.]

[Why don’t immune checkpoint inhibitors work in colorectal cancer?]

SHI Yuequan, ZOU Zifang, KERR David

[In recent years, immune checkpoint inhibitors have been shown to be effective in treating manifold types of cancer but less robust in colorectal cancer (CRC). While, the subgroup of CRC with microsatellite instability (MSI; also termed as mismatch repair defi cient) showed a moderate response to Pembrolizumab in a single arm phase II clinical trial, microsatellite stable (MSS) cancers were unresponsive. Possible mechanisms that affect immune response in colorectal cancer will be reviewed in this article. We will also propose that histone deacetylase (HDAC) inhibition may reverse the immune editing commonly seen in advanced CRC and render them sensitive to immune checkpoint blockade.]

[The beneficial effects of angiotensin-converting enzyme inhibitors on biochemical and vascular markers have been proven by many experimental studies. Reduction of the angiotensin-II level has a positive effect on oxidative stress, lipid peroxidation, apoptosis, inflammatory and prothrombotic processes. Two large multicentric trials, EUROPA and HOPE, showed that perindopril and ramipril significantly reduce mortality and the risk of both fatal and non-fatal cardiovascular events in patients with atherosclerosis, thereby making them the base drugs of secondary prevention of coronary artery disease.]

[The importance of recognition and proper treatment of hypertension and the maintenance of adherence in hypertension care]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Hypertension is the leading cause of death and disability-adjusted life years. In the United States hypertension accounts for more cardiovascular (CV) deaths than any other modifiable CV disease risk factor and was second only to cigarette smoking as a preventable cause of death for any reason. In our country the situation is similar. In Hungary the number of subjects with hypertension is approximately 3.5 million and this high prevalence contributes markedly to the poor Hungarian CV morbidity and mortality figures. The recognition of hypertension, the initiation of drug therapy and the long-term follow- up of the patients is mainly the task of primary care. Besides that it inheres high responsibility, this is also a grateful commitment, as hypertension in most of the cases can be treated properly with lifestyle-changes and medications leading to a marked decrease of CV complications, especially stroke. In our review article we would like to focus on the high prevalence of hypertension worldwide as well as in our country, the exact implementation of screening, the risk reduction potential of the proper treatment and the importance of the long-term maintenance of treatment adherence.]

[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.]
