Patients and 2 Methods: Between July 2007 and May 2012 we evaluated 62 ROLE OF HIGH GRADE INTRAEPITHELIAL patients (range 56-76 years) who underwent consecutive RP NEOPLASIA AS A RISK FACTOR (48 with the open technique and 14 with the laparoscopic FOR PROSTATIC CANCER technique) with recovery of biochemical disease (PSA >0.2 Lucio Dell’ Atti , Gian Rosario Russo ng/ml). The pathologic stages of patients were: 27pT2, 33pT3 and 2pT4 respectively. All patients had negative lymph nodes Urologia, Azienda Ospedaliero-Universitaria Arcispedale S. and only one pT4 had positive surgical margins. All patients Anna, Ferrara, Italy with suspected local recurrence were subjected to rectal examination and transrectal ultrasound-guided biopsy Introduction: High grade prostatic intraepithelial neoplasia perianastomotic (BTP) using an “end-fire” multi-frequency (HGPIN) is traditionally considered as a precancerous convex probe under local anesthesia with lidocaine spray conditions. The majority of patients with diagnosed HGPIN are (10g/100ml). Results: Patients were divided into two groups. expected to develop prostate cancer (PC) within 10 years (1). Group A: 33 patients with mean PSA 2.3 ng / ml, subjected to The degree of association between HGPIN and PC in different BTP: 14/33 (42%) and 19/33 (57%) respectively four and six sources of literature ranges between 22% and 80% (2, 3).There biopsies. Group B: 29 patients with mean PSA 1.4 ng / ml is a controversy regarding the role of HGPIN as a risk factor underwent a standard eight biopsies. Among patients in the for PC. The aim of the present study was to evaluate the role of latter group, three had already undergone four biopsies. One HGPIN in prediction of adverse pathology in patients patient belonging to group B did not complete the entire biopsy undergoing a radical prostatectomy (RP). Patients and procedure because of discomfort. In the first group signs of Methods: We retrospectively analysed 210 patients who local recurrence were observed in 11/33 (33%), while in 22/33 underwent a RP (open or laparoscopic) between July 2007 and (66%) residual benign prostate tissue was found in six biopsies December 2010 at a single referral center. Exclusion criteria and fibrous tissue and scar in sixteen. In Group B: 22/29 (76%) were any preoperative treatment protocol, active surveillance, were found with prostate cancer relapsed, whereas 7/29 (24%): hormone therapy and radiotherapy. The relationship between prostate tissue residue was found in two biopsies fibrous tissue HGPIN and the presence of positive surgical margins (PSM), and scar in five biopsies. Discussion and Conclusion: The extracapsular disease (ECD), seminal vesicle invasion (SVI) present study raises the possibility that residual and benign and lymph node invasion (LNI) was analysed. Patients were tissue, resulting from unintentional disruption of the prostatic stratified into low (PSA <10 ng/ml, cT1, biopsy Gleason sum capsule during surgery, may be responsible for a detectable ≤6), high (cT3 or biopsy Gleason 8-10 or PSA >20 ng/ml) and postoperative PSA. The clinical significance of prostatic intermediate risk (all the remaining patients). The prognostic residual tissue in follow-up is most important since it can be value of HGPIN was estimated in each risk group separately. responsible for biochemical failure and can increase in size, Results: The median age was 66.7 years (range 48-77) and simulating in this way a local recurrence. Although there was median PSA was 8.5 ng/ml (range 2.5-16). Based on the no evidence of a significant correlation between PSA levels to preoperative clinical staging, 139 (66%) patients were T1c, local recurrence, Gleason score and positive biopsy, the BTP 51(24%) T2a, 17(8%) T2b and 3(1.5%)T2c.

Furthermore, miRNAs correlation was found between HGPIN and preoperative PSA might be potential targets for novel therapeutic strategies, (p= 0.025) and patients’age ( p= 0.030).

Materials and Methods: Analysis of PSA. However, there was no significant difference in the tumor miR501-5p expression was performed by real time RT-PCR. grade and pathological stage between groups.
