[Adjuvant treatment of kidney tumors - a more successful future?] / Vesedaganatok adjuváns kezelése ­ sikeresebb jövo?

Considering the data of the past years, the number of kidney tumor patients grows constantly. These patients are usually found incidentally with the help of common imaging procedures. The classic triad - lower back pain, bloody urine, and palpable flank terime - occurs rarely. Their presence foresees an advanced disease. In our article, in addition to the mentioning of the epidemiological and etiological data, symptoms, surgical therapy and histological types of the kidney tumors, we present the adjuvant treatment options, their types and effectiveness.

[Prostate cancer screening - past, present, future]. / A prosztatarák szurése ­ múlt, jelen, jövo.

Prostate cancer is one of the most significant cancers among men. In addition to epidemiological and etiological data, this summary provides a description of the most important features of prostate specific antigen, used most, and other markers that can make easier to diagnose the disease. It presents the major international and Hungarian studies dealing with prostate cancer screening, including the economic aspects. Genetic tests, DNA- and RNAbased biomarkers are gaining more and more space, they can even help us in screening and avoiding overdiagnosis. The main goal of the future researches should be to develop methods that can be used to detect prostate cancer at an early, curable stage.

Circulating and tissue IMP3 levels are correlated with poor survival in renal cell carcinoma.

Tissue protein expression of IMP3 is emerging as a promising prognostic factor in renal cell carcinoma (RCC). The most commonly used immunohistochemical (IHC) antibody has been criticized for its low specificity. In addition, blood levels of IMP3 have not yet been analyzed in RCC. Therefore, we compared the prognostic performance of two different IMP3 IHC antibodies and assessed the prognostic relevance of IMP3 plasma levels in RCC. IMP3 levels were assessed in an overall number of 425 RCC (344× clear cell [ccRCC], 63× papillary [pRCC], 18× chromophobe [chRCC]) patients in three partly overlapping cohorts. Plasma IMP3 concentrations were determined by ELISA in 98 RCC (79× ccRCC, 15× pRCC, 4× chRCC) patients and 20 controls. IMP3 mRNA expression levels were analyzed in 73 frozen tissue samples (55× ccRCC, 12× pRCC, 6× chRCC), while protein expressions were assessed in 366 FFPE samples (294× ccRCC, 56× pRCC, 16× chRCC) using the M3626 and N-19 antibodies. IMP3 plasma and mRNA expression levels were significantly higher in patients compared to controls and in high-grade compared to low-grade tumors. In addition, IMP3 plasma and tissue protein levels (by M3626) were higher and IMP3 mRNA expression levels tended to be higher in patients with distant metastasis. Multivariate analyses in clear cell RCC revealed high IMP3 plasma concentration and mRNA expression as independent predictors of disease-specific survival. IMP3 immunostainings by M3626 but not by N-19 were independently associated with poor overall and disease-specific survival. High plasma and tissue levels of IMP3 are independently associated with poor RCC prognosis. The applied antibody significantly impacts the prognostic performance of analysis. IMP3 analysis may improve risk-stratification of RCC patients and therefore could help to optimize therapeutic and follow-up decisions.
