Abstract: Introduction: Mortality of prostate carcinoma can be significantly decreased by the use of modern diagnostic and therapeutic options. Patients in early stages can be cured by radical surgery or radiotherapy. Aim: Overview and comparison of previous and present diagnostic and therapeutic methods regarding accuracy of diagnosis, improvement of efficiency and decrease of toxicities. We also aimed to explore general correlations in case of serious complications. Method: By the help of two prostate cancer patients we demonstrate the importance of accuracy and change of histological diagnosis, significance of proper imaging techniques, and also show parameters of conventional and modern radiotherapy and their acute and chronic complications. Differences of previous and present methods and their consequences were analyzed. Results: By now, histological findings in the patients’ diagnosis have changed. Both patients received conventional three-dimensional definitive radiotherapy in 2009–2011, and their prostate cancer was cured. In one case, urinary bladder also received radiotherapy because prostate carcinoma had infiltrated it. In the other case, the contemporary radiotherapy involved urinary bladder’s fundus due to safety margins. Although acute grade 2 cystitis developed in both cases and recovered in several weeks, as late complication bladder shrinkage developed, which after the ineffectiveness of conventional therapies had to be cured by radical cystoprostatectomy – in order to cease bleeding and to cure incontinence. Conclusions: In case of prostate carcinomas, serious complications can be avoided by the improvement of diagnostic and therapeutic options. Synthesis of data could be more successful if they were analyzed in the light of previous experiences. Orv Hetil. 2018; 159(32): 1317–1325.
