Item Are the Recommended Criteria for Clinically Insignificant Prostate Cancer Applicable to 12-core Prostate Biopsy Scheme? A Multicentre Study of Urooncology Association, Turkey(GALENOS PUBL HOUSE, 2021-01-01) Celik, Serdar; Kizilay, Fuat; Yorukoglu, Kutsal; Ozen, Haluk; Akdogan, Bulent; Izol, Volkan; Bayazit, Yildirim; Aslan, Guven; Sozen, Sinan; Baltaci, Sumer; Muezzinoglu, Talha; Narter, Fehmi; Turkeri, Levent; Assoc, UrooncologyObjective: The aim of this study is to investigate the relevance of the Epstein criteria for the 12-core transrectal prostate biopsy (TRUS-Bx) scheme with the evaluation of clinicopathologic data recorded in the Urologic Cancer Database - Prostate (UroCaD-P), Urooncology Association, Turkey (UOAT). Materials and Methods: Patients with detailed pathological 12-core TRUS-Bx data for each biopsy core and who underwent RP due to PCa were included in this study. A total of 1167 patients from seven different centres were analysed. TRUS-Bx pathological findings were separately evaluated in the areas matching the sextant biopsy (6-core paramedian-lateral) scheme and in all 12-core biopsy areas (12-core biopsy scheme). Overall detection rates of PCa and ratios of clinically significant (sPCa) and insignificant PCa (insPCa) after RP were defined and compared between the biopsy schemes. Biopsy findings, according to the Epstein criteria, were also compared between the two schemes. A model for each biopsy scheme was created, including the Epstein criteria and additional biopsy findings using logistic regression analysis to predict clinically sPCa after RP. Results: There was a high correlation for the prediction of clinically insPCa between the two biopsy schemes in the same population. However, 7.3\% of PCa could not be diagnosed in the 6-core TRUS-Bx scheme. Also, 69.4\% of these had clinically sPCa according to the Epstein criteria in 12-core TRUS-Bx scheme and 51.8\% of these were clinically sPCa after RP. The presence of perineural invasion (PNI) in 12-core biopsy was also significant regarding predicting sPCa (p<0.001). Conclusion: The Epstein criteria in 12-core prostate biopsy provide a better prediction of clinically sPCa than the 6-core biopsy scheme. Biopsy PNI findings appeared to improve the effectiveness of 12-core prostate biopsy, in addition to the Epstein criteria.Item Turkey Prostate Cancer Map 2021: Turkish Urooncology Association Prostate Cancer Database Report(GALENOS YAYINCILIK, 2022-01-01) Sahin, Bahadir; Celik, Serdar; Tinay, Ilker; Eskicorapci, Saadettin; Aslan, Guven; Sozen, Sinan; Ataus, Suleyman; Turkeri, LeventObjective: This study aimed to present the data of patients with prostate cancer (PCa) whose detailed information was stored in the Urologic Cancer Database-Prostate, Urooncology Association, Turkey with the title of ``Turkey Prostate Cancer Map 2021.{''} Materials and Methods: Patient data between 1995 and 2020 were retrospectively scanned. The age of the patients, their distribution according to age groups, symptoms during diagnosis, examination findings {[}digital rectal examination (DRE)], prostate-specific antigen (PSA) values, biopsy methods in the diagnosis, metastatic disease rates, treatment methods, and progression rates at follow-up were examined. These results were compared with the results of the previous report, namely ``Prostate Cancer Incidence (Incidence) in Turkey,{''} by the Urooncology Association in Turkey in 2009. Results: This study analyzed the data of 5040 patients from 19 different centers. The mean patient age was 63.6 (37-97) years. The age distribution examination revealed that most patients (49.8\%) were aged 60-69 years. Of the patients, 51.8\% were symptomatic at the time of diagnosis. The presence of symptoms was determined in 88.6\% in 2009 data. The ORE of patients revealed that 25\% of patients had malignancy findings. The PSA distribution examination revealed a >10 ng/mL PSA value in 37.5\% of patients. With the increasing use of magnetic imaging resonance (MRI) in PCa diagnosis over the years, increased MR-fusion biopsy rates have been observed. Considering the biopsy data, 91\% of patients were diagnosed with a classical transrectal ultrasound-guided biopsy, whereas 9\% were diagnosed with MR-Fusion biopsy. Fusion biopsies revealed that 23\% of patients with Prostate Imaging-Reporting and Data System (PI-RADS) 4 lesion and 57\% with PI-RADS 5 lesion were diagnosed with cancer. Of the patients, 8.9\% of patients had metastases during the initial diagnosis. This rate was 17\% in 2009 data. The treatment methods examination after the diagnosis revealed that 73.9\% of patients had undergone radical prostatectomy. This rate was 51.8\% in 2009. Robotic and laparoscopic approaches, which are among the surgical modalities, have increased over the years. However, the most frequently applied modality in our country was open radical prostatectomy with 62.6\%. Considering the follow-up data after treatment, 8.9\% of patients had progression, of which 62.6\% was biochemical, 30.2\% was radiological, and 6.9\% was a clinical progression. Conclusion: Technological advancements for PCa diagnosis (MRI and MR-guided biopsies) are becoming a routine part of daily practice compared to the results of the ``Prostate Cancer Incidence in Turkey{''} project in 2009. The comparative study results revealed that the rate of symptomatic and metastatic disease decreases at the time of diagnosis, and laparoscopic and robotic surgery methods are used at increasing rates for localized disease.Item Comparison of TRUS and combined MRI-targeted plus systematic prostate biopsy for the concordance between biopsy and radical prostatectomy pathology(WILEY, 2021-01-01) Aslan, Guven; Celik, Serdar; Sozen, Sinan; Akdogan, Bulent; Izol, Volkan; Bilen, Cenk Yucel; Sahin, Bahadir; Turkeri, Levent; Assoc, UrooncologyAim: To evaluate the accuracy in histologic grading of MRI/US image fusion biopsy by comparing conventional 12-core TRUS-Bx at radical prostatectomy specimens (RP). Methods: Consecutive patients diagnosed prostate cancer (127 with combination of both targeted biopsy (TBx) plus systematic biopsies (SBx) and separate patient cohort of 330 conventional TRUS-Bx without mpMRI) with a PSA level of <20 ng/mL prior to RP were included. The primary end point was the grade group concordance between biopsy and RP pathology according to biopsy technique. Results: Clinically significant prostate cancer detection was 51.2\% for TRUS-Bx, 49.5\% for SBx, 67\% for TBx and 75.7\% for TBx + SBx. Upgrading and downgrading of at least one Gleason Grade Group (GGG) was recorded in 43.3\%/ 6.7\% patients of the TRUS-Bx and in 20.5\%/ 22\% of the TBX + SBx group, respectively (all P <.001). Concordance level was detected to be significantly higher for ISUP 1 in combined TBx + SBx method compared to conventional TRUS-Bx (61.3\% vs 37.9\%, P =.014). In ISUP 1 exclusively, significant upgrading was seen in TRUS-Bx (62.1\%) when compared to TBx (41.4\%) and TBx + SBx (38.7\%). Conclusions: MRI-targeted biopsies detected more significant PCa than TRUS-Bx but, superiority in significant cancer detection appears as a result of inadvertant selective sampling of small higher grade areas. Within an otherwise low grade cancer and does not reflect accurate GGG final surgical pathology. TBx + SBx has the greatest concordance in ISUP Grade 1 with less upgrading which is utmost important for active surveillance.Item Management of Patients with Urological Cancers in Turkey during the COVID-19 Pandemic: Recommendations of Uro-oncology Association(GALENOS YAYINCILIK, 2020-01-01) Celik, Serdar; Tinay, Ilker; Narter, Fehmi; Eskicorapci, Saadettin; Ataus, Suleyman; Turkeri, Levent; Baltaci, SumerCoronavirus disease-19 (COVID-19) has been declared as a pandemic by the World Health Organization. The number of cases has increased over time in correlation with the increasing number of testing worldwide. In order to use the available resources for COVID-19 treatment, urological practice has been limited only to emergency procedures and certain uro-oncological surgeries. In this report, we aim to share our recommendations for the daily uro-oncology practice in light of local circumstances in Turkey.
