Abstract
English
Prostate carcinoma is the most frequently diagnosed cancer in men in Germany. It is crucial to recognise clinically significant carcinomas at an early stage. Prostate biopsy is the preferred diagnostic method for this. Targeted samples are sometimes taken as part of the MRITRUS fusion biopsy. In order to be able to plan and remove the targeted punch cylinders, the surgeon is supported in advance with as much information as possible about the suspicious lesions. The aim of this study is to examine whether MRI findings with a higher amount of information can contribute to an increased detection rate in the context of MRI-TRUS fusion biopsy. The study examined 222 male patients who underwent MRI/TRUS fusion biopsy of the prostate at the Department of Urology at the University Medical Centre Göttingen between 1 January 2016 and 31 December 2017. The available findings were evaluated using a score and then grouped. Subsequently, the overall collective and the respective groups of findings were analysed. In the group (N=192) with the highest score, the targeted punch biopsy detected PCa in 16% and significant PCa in 37%. This difference was significant in the paired comparison. In the groups with an average information density (N=22) according to the score, 22 % PCa and 14 % significant PCa were detected in the targeted punch biopsies. 13 % significant PCa were detected in the group with less information (N=8). The present study was able to show that findings with a higher information content exhibit increased detection in targeted punch biopsies of prostate carcinomas, especially significant prostate carcinomas.
