Cancer - Prostate(구연) (E-112) MR fusion biopsy는 초보자의 경험의 차이를 극복할수 있게 해줄까? 부산대학교 의과대학 비뇨기과학 교실 이권경, 박시균, 강병진, 박지훈, 김경환, 구자윤, 하홍구 MR fusion targeted biopsy can overcome adversity versus experted Prostate biopsy Introduction & objectives> As is well known, it is understood that the Cancer detection rate(CDR) in prostate biopsy varies according to the experience. Besides that, MR fusion Targeted biopsy(MRBx) is known to be more effective in the detection of clinically significant PCA (csPCA, GS>6) than clinically insignificant PCA (GS=6) Thus, we analyzed the effectiveness of Sono-guided Systematic biopsy(SBx) and MRBx, and assessed whether MRBx can help beginners overcome differences in experience. Materials & Methods> We have monitored 1,561 prostate biopsy samples, which were performed between 2017.03 and 2019.02. Of these, only biopsy performed by A, B and C was classified and only the patients under PSA10, which is gray zone, were included. <Table 1> Result> If you look at A and C, who tried more MR fushions as a beginner, gradually between 20 and 40 cases, the overall CDR and cs PCA DR do not show much difference. B, on the other hand, shows gradual increase to 100 cases. (Row1,2) What`s more surprising is that only 10th case of MRBx by A & C show significant increases in overall CDRs and csPCA DR (Row4 A,C) This is because A & C tried more MRBx as a beginner, obviously (Row1 A,C) But because why B tried MRBx more after 100 cases(Row1 B), he get only gradual increase in overall CDRs and csPCA DR(Row2 B) Concluision> It can be possible that More try MRBx at the begin, Eariler you get experts hands keywords : MR fusion biopsy, Systematic biopsy, beginner
