Background/aim: This study aims to compare the success rates of rigid registration (RR) and elastic registration (ER) systems in diagnosing all cancers and clinically significant prostate cancer (csPC) in software-based targeted prostate biopsies (TPBs) by performing matching analysis. Materials and methods: The data of 2061 patients from six centers where software-based TPB is performed were used. All cancer and csPC detection rates of the RR and ER systems were compared following Mahalanobis distance matching with the propensity score caliper method. Logistic regression analysis was applied to identify factors predicting clinically insignificant prostate cancer (ciPC) and csPC diagnoses. Additionally, the International Society of Urological Pathology Grade Group (ISUP GG) upgrade rates of RR and ER systems were compared between biopsy and radical prostatectomy pathologies. Results: The matched sample included 157 RR and 157 ER patients. No statistically significant difference was found between ER and RR in terms of csPC detection rate (28.0% vs. 22.3% respectively, p = 0.242). The detection rate of all cancers by ER compared to RR was found to be significantly higher (54.8% vs. 35.7% respectively p < 0.001,). No statistically significant difference was found between the ER and RR groups regarding pathological upgrade (39.7% vs. 24.2% respectively, p = 0.130). In the logistic regression analysis performed to determine the factors predicting ciPC, decreased prostate volume and ER system use were found to be independent predictive factors. Conclusion: While the detection rate of csPC was similar for the RR and ER systems, the detection rate of all cancers and ciPC was significantly higher with the ER systems. [ABSTRACT FROM AUTHOR]

Objective: To assess the impact of surgical delay in localized prostate cancer (PCa) on adverse pathological features and oncological outcomes. Materials and Methods: Patients who underwent surgery for localized PCa were included from the Turkish Urooncology Association PCa database. History of previous treatment or active surveillance was considered an exclusion criterion. Patients were divided into two groups according to the time period between the diagnosis and surgery; less than or equal to 90 days (group 1) or longer than 90 days (group 2). Surgical pathology results and oncological outcomes were compared between the groups. Results: In total, 2454 out of 3646 patients were assessed. Pathological findings of radical prostatectomy specimens were similar between the two groups. However, there was slightly more seminal vesicle invasion in the final surgical pathology in group 1 (12.9% vs. 9.3%, respectively p=0.042). The 5-year biochemical recurrence-free survival times were similar across all D'Amico risk categories between the two groups. The regression analysis demonstrated seminal vesicle invasion as the only factor affecting the time to prostate-specific antigen progression in high-risk patients (p<0.001 HR=2.51 confidence interval=1.58-4.45). Conclusion: In conclusion, our results in this large cohort suggest that surgical delay does not cause a deterioration in PCa surgical outcomes, even in high-risk patients. These findings may be helpful for planning limited healthcare resources especially in conditions like the coronavirus disease-2019 pandemic where the availability and optimal use of healthcare system resources are crucial.

Objective: To investigate the effect of the International Society of Urological Pathology (ISUP) grade group 4 (GG4) and ISUP GG5 subgroups according to prostate biopsy on biochemical recurrence (BCR). Materials and Methods: Patients who underwent radical prostatectomy (RP) after being diagnosed with GG4 and GG5 prostate cancer according to prostate biopsy and who had follow-up data were retrospectively evaluated. Patient data were obtained from the Urologic Cancer Database-Prostate of the Turkish Urooncology Association. GG4 and GG5 pathologies were evaluated using Gleason subgroups. The effect of clinicopathological parameters on BCR after RP was investigated separately in the GG4 and GG5 patient groups. Results: In GG4, 73 of 188 patients developed BCR. When GG4 patients were evaluated for BCR, only lymphovascular invasion was significant for BCR (p=0.004). In addition, seminal vesicle invasion (SVI) and high ISUP grade according to RP pathology were significant in patients with BCR (p=0.004 and p=0.005). In the follow-up of 145 patients with GG5, 80 patients developed BCR. When GG5 patients were evaluated for BCR, no predictive factor was found for developing BCR. However, surgical margin positivity, extraprostatic extension, and SVI after RP were found to be significant in patients with BCR (p=0.031, p=0.011 and p=0.007). Conclusion: According to our results, the ISUP GG system, which does not include Gleason subgroups, is an appropriate classification system for GG4 and GG5 patients for the prediction of BCR in the Turkish patient population, in parallel with the current literature.

To assess the incidence, risk factors, and timing of specific causes of reoperations following PVP. A retrospective analysis of data on men who underwent GreenLight PVP between 2004 and 2019 in a single center and required surgical intervention for bladder neck contracture (BNC), urethral stricture (US), or persistent/recurrent prostate adenoma. The overall rate of reoperations was 13.8% during a 61-month median follow-up of 377 patients. Reoperations were due to BNC, US, and adenoma in 7.7%, 5.6%, and 4.8% of cases, respectively. The median interval until reoperation for US (11 months) was significantly shorter. None of the risk factors had any relevance to US. In patients who underwent reoperation for BNC, lasing time and energy were significantly lower, and the prostate volume was smaller; however, the multivariate analysis only identified shorter lasing time as a predictor. In patients who had reoperation for persistent/recurrent adenoma, the PSA was increased, while the prostate volume was non-significantly high, and performance by less-experienced surgeons was associated with a higher rate of reoperations (p < 0.05). A longer lasing time predicted an increased risk of reoperation for adenoma in multivariate analysis. An unselective utilization of PVP may result in a relatively high rate of reoperations. The correlation of BNC with shorter lasing time may imply a higher risk after PVP of smaller prostates. A longer lasing time predicts an increased risk of reoperation due to persistent/recurrent adenoma, which may be related to higher prostate volumes and inefficient PVP by less-experienced surgeons.

Objective: To evaluate clinicopathological features of patients with serum prostate-specific antigen (PSA) level of ≤3 ng/mL and diagnosed with prostate cancer (PCa). Materials and Methods: A total of 34 male patients diagnosed with PCa by either prostate needle biopsy (PNB) or transurethral resection of the prostate (TUR-P) were included in this study between January 2010 and June 2021. Patients whose preoperative serum PSA level was >3 ng/mL and those with missing clinical data were excluded. Preoperative clinical characteristics of the patients and pathological findings of PNB, TUR-P, and radical prostatectomy (RP) specimens were evaluated. Results: The median age of the patients was 65 (60-69) years. The median preoperative serum PSA level was 1.98 (1.45-2.64) ng/mL. PCa was detected by "systematic prostate biopsy (SBx) only", combined prostate biopsy [SBx following multiparametric magnetic resonance imaging-targeted prostate biopsy (TBx)], and "TUR-P" in 6 (17.6%), 17 (50.0%), and 11 (32.4%) patients, respectively. In combination of both biopsy, PCa was detected in "SBx specimens only", "TBx specimens only", and "both TBx and SBx specimens" in 3 (8.8%), 5 (14.7%), and 9 (26.5%) patients, respectively. Clinically significant (cs) PCa was in 52.9% of the TBx (9/17) and 60.9% of the SBx (14/23) specimen. Twenty (58.8%) patients treated with RP. csPCa in RP specimens was observed in 17/20 (85.0%) patients. Upgrading in RP specimens compared with PNB specimens was observed in 5/11 (45.5%) of the TBx and 9/17 (52.9%) of the SBx specimen. At the final RP pathology, International Society of Urologic Pathology-grade group >3 or non-organ confined disease were observed in 8 (40%) and 8 (40.0%) patients, respectively. Conclusions: Adverse pathological outcomes in RP specimens are frequent in patients with PCa with a serum PSA level of ≤3 ng/mL at the time of diagnosis, and physicians should be aware of the limitations of pre-set PSA cut-off levels.

Objective: In this study, we investigated the correlation between prostate imaging reporting and data scoring system (PIRADS) grades of patients' prostate lesions detected by multiparametric prostate magnetic resonance imaging (MpMRI) and prostate specific antigen (PSA) values obtained before prostate biopsy and its role in predicting clinically significant cancer in prostatectomy specimens. Materials and Methods: Patients who underwent biopsy and were diagnosed with prostate cancer (PCa) because of positive or negative MpMRI were evaluated. Histopathological factors were recorded, and the relationship between the PIRADS grading system and PSA values was analyzed in patients who underwent radical prostatectomy and preoperative MpMRI. PSA cut-off values predicting clinically significant PCa (CSPCa) in MpMRI were calculated. Results: A total of 1,319 patients were included in the study. MR-fusion biopsy was performed in 58% of the patients, and malignant histopathology was detected in 49% of the patients. While 87% of the patients had CSPCa, 13% had clinically insignificant PCa. The sensitivity and specificity of the PSA 4 ng/mL cut-off value were 88.6% and 15.1% in all patient groups, respectively. In predicting CSPCa, sensitivity was 88.9% and specificity was 18.8% for PSA 4 ng/mL cut-off value in MpMRI-negative patients. If PSA >4 ng/mL in MpMRI-negative patients, there is a >45% PCa detection rate in biopsy, but biopsy is more appropriate for PSA >10 ng/mL for CSPCa. In MpMRI-positive patients, if PSA is >2.5 ng/mL, biopsy provides a >50% PCa and >30% CSPCa diagnosis. If there are PIRADS 5 lesions and PSA is >2.5 ng/mL, biopsy has a >70% PCa and >60% CSPCa detection rate. Conclusions: It may be appropriate to consider higher PSA cut-off values (PSA >10 ng/mL) to make a biopsy decision in patients with negative MpMRI, whereas it may be possible to detect CSPCa at lower PSA values in patients with positive MpMRI findings and high PIRADS grade.

Objective: Testicular tumors can be seen bilaterally in 2-3% of cases as synchronous or metachronous. The long cancer-specific survival in early-stage testicular cancer requires consideration for fertility and quality of life issues because of organ loss in these patients. In the present case series, the surgical outcome and histopathological features of testis-sparing surgery were evaluated using bench work after a standard radical orchiectomy in testicular tumor patients with normal contralateral testis. Materials and Methods: Patients with a testicular mass confirmed by ultrasonography and/or magnetic resonance imaging and normal contralateral testis were included in the study. All patients underwent standard radical orchiectomy. Partial orchiectomy was performed on a separate operating table (bench) following radical orchiectomy. After visual evaluation of the removed tumor mass, seven biopsies were taken from the tumor bed for frozen section examination (FSE). If a residual tumor was found in the tumor bed because of FSE, parenchymal resection was performed until a negative margin was achieved. The patients' age, tumor marker levels, tumor type, tumor diameter, rete testis invasion, epididymis and spermatic cord invasion, necrosis, and presence of lymphatic-vascular invasion were recorded. Results: Sixteen patients were included in the study. The mean age of the patients was 31.6±11.6 years. The mean tumor diameter was 26.9±15.3 mm, and the mean tumor-testicular-volume ratio was 33.2±24.9 percentage. The surgical margin was positive in 12.5% (n=2/16) patients in the FSE. In these two patients, the tumor-testicular volume ratio was above 50%, the tumor diameter was greater than 50 mm, and necrosis and invasion of the tunica albuginea were observed in the final histopathology. The tumor histopathology of patients was pure seminoma, non-seminomatous germ cell tumors, mixed germ cell tumor, sex cord stromal tumor, and fibrosis in 50% (n=8/16), 12.5% (n=2/16), 25% (n=4/16) 6.5% (n=1/16) and 6.5% (n=1/16) of the cases, respectively. Histopathological examination revealed 37.5% (n=6/16) intratubular germ cell neoplasia in the adjacent testicular tissue. Conclusion: Our experience in the present case series shows that testis-sparing surgery is technically straightforward. Surgical margin positivity can be detected in patients with a large tumor or a high tumor-testicular-volume ratio. FSE is useful for detecting surgical margin positivity. [ABSTRACT FROM AUTHOR]

Objective: This report examined the approaches to low-risk patients using the data from the Urologic Cancer Database - Prostate, Urooncology Association. Materials and Methods: In this study, there were 920 patients with low-risk prostate cancer according to the current guidelines of the European Urology Association. Patient data were obtained from the Urological Cancer Database - Prostate, the Turkish Urooncology Association (UroCaD-P) from records of the years 1995-2021. Ethics committee approval was obtained for this study to publish in the form of a database report. Results: Our study was conducted with 920 patients with low-risk prostate cancer. Therefore, at the time of diagnosis, all patients in the study were ISUP 1, had a prostate specific antigen (PSA) level lower than 10 ng/mL, and clinically T1-T2a. Surgical treatment was used in 750 (81.5%) of the patients. At the time patients were retrieved from the database for the study, 140 patients (15.2%) were in the active surveillance (AS) process. Thirty patients (3.2%) in the study received their local treatment as radiotherapy (RT). The mean age value at cancer detection in the study was 61.9. The mean ages of the patients who were under AS and who underwent radical prostatectomy (RP) were 61.3 and 61.7 years, respectively. In the RT group, the mean age was 66.7 years. The mean PSA value of the whole group was 5.81 ng/mL. While it was 5.94 in AS patients, it was calculated as 5.89 in patients who underwent radical surgery. The mean PSA value of the RT group was 5.40. The pathological upgrade was detected in 225 patients (30%) after surgery. Surgical margin positivity was in 160 of the patients (21.3%) who underwent surgery. In addition, 100 patients (13.3%) had extracapsular disease. The seminal vesicle invasion was detected in 25 patients (3.3%) after surgery. Conclusion: We predict that the incidence of low-risk prostate cancer will increase over time due to the aging of the population, the use of PSA, advances in imaging modalities, and increasing biopsy success rates. Therefore, the importance of the existence of multicentric databases containing this patient group is undeniable. More studies are needed with these databases, including both patient demographics and treatment outcomes. Hopefully, this database report will be an important step in this direction.

Objective: This study aimed to determine the predictive factors for patients whose International Society of Urological Pathology (ISUP) score was upgraded in radical prostatectomy (RP) pathologies with a prostate biopsy pathology of ISUP grade group 1. Materials and Methods: Among patients who underwent RP in our clinic within 10 years, 158 patients with prostate biopsy pathology of ISUP grade group 1 were examined retrospectively. Age, serum prostate-specific antigen (PSA) level, prostate biopsy ISUP grade group, number of cores taken in the prostate biopsy, number of tumor-positive cores, RP pathology ISUP grade group, and pathological stage were evaluated. Results: The mean age (± standard) of the 158 patients whose prostate biopsy pathology was ISUP grade group 1 were 64.07 (±6.6). ISUP group upgrading was detected in 47 patients (29.7%). The mean PSA value of these patients was 10.6 ng/mL (±6.9). The mean PSA value of the other 111 patients without ISUP group upgrading was 7.98 ng/mL (±4.9). The serum PSA level was significantly higher in patients with upgraded ISUP in the RP pathology (p=0.02). The percentage of tumor-positive cores in the group with ISUP group upgrading (37%) was significantly higher than that in the group without ISUP group upgrading (27%) (p=0.01). The detection rates of surgical margin positivity (42.6% vs. 18%), capsule invasion (55.3% vs. 19.8%), and seminal vesicle invasion (23.6% vs. 3.6%) were also significantly higher in the upgraded ISUP group after RP (p<0.05). Conclusion: The results of this trial suggest that active surveillance may not be an appropriate option for patients with biopsy ISUP grade group 1 with PSA level >10 ng/mL. Moreover, the presence of a higher number and percentage of tumor-positive cores constituted risks of ISUP group upgrading with concomitant poor pathological outcomes such as surgical margin positivity, capsule invasion, and seminal vesicle invasion.

Objective: 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 DRE 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.

Objective: This study aimed to assess and compare the conventional and Retzius-sparing robot-assisted radical prostatectomy (cRARP and RsRARP) in term of perioperative clinical, pathological, and oncological outcomes. Materials and Methods: This study included 238 consecutive male patients who underwent RARP between May 2008 and November 2020. RARP operations were performed by a single-surgeon. Patients were divided into groups according to the surgical approach and were statistically compared in terms of perioperative clinical, final pathological, and oncological outcomes. Results: The mean age of patients was 64±7 years. cRARP was performed in 134 (56.3%) patients, whereas RsRARP in 104 (43.7%). The frequency of patients with the American Society of Anesthesiologists Class-2 score was higher in the RsRARP group (p<0.001). The median surgery duration was 300 (270-360) min. The median surgery duration was shorter in RsRARP group (290 vs. 330 minute) (p<0.001). No difference was found between the groups in terms of estimated blood loss and postoperative complication rates (p=0.112 and p=0.182, respectively). No difference was found between the groups when they were compared for surgical margin positivity (p=0.453). Although not statistically significant, the frequency of surgical margin positivity with pT3a/pT3b disease was higher in patients who underwent cRARP (p=0.412 and p=0.261, respectively). At a median follow-up of 13 (6-36) months, no difference was found between the groups in terms of biochemical recurrence at months -3,-6,-9,-12,-18,-24, and -30, respectively (p>0.05, for each). Conclusion: RsRARP allows a safe operation with a shorter surgical time and similar surgical margin positivity, oncological outcomes, and complication rates compared to cRARP. [ABSTRACT FROM AUTHOR]

Background: Epstein criteria based on sextant biopsy are assumed to be valid for 12-core biopsies. However, very scarce information is present in the current literature to support this view. Objectives: To investigate the validity of Epstein criteria for clinically insignificant prostate cancer (PCa) in a cohort of the currently utilized 12-core prostate biopsy (TRUS-Bx) scheme in patients with low-risk and intermediate-risk PCa. Method: Pathological findings were separately evaluated in the areas matching the sextant biopsy (6-core paramedian) scheme and in all 12-core schemes. Patients were divided into 2 groups according to the final pathology report of RP as true clinically significant PCa (sPCa) and insignificant PCa (insPCa) groups. Predictive factors (including Epstein criteria) and cutoff values for the presence of insPCa were separately evaluated for 6- and 12-core TRUS-Bx schemes. Then, different predictive models based on Epstein criteria with or without additional biopsy findings were created. Results: A total of 442 patients were evaluated. PSA density, biopsy GS, percentage of tumor and number of positive cores, PNI, and HG-PIN were independent predictive factors for insPCa in both TRUS-Bx schemes. For the 12-core scheme, the best cutoff values of tumor percentage and number of positive cores were found to be ≤50% (OR: 3.662) and 1.5 cores (OR: 2.194), respectively. The best predictive model was found to be that which added 3 additional factors (PNI and HG-PIN absence and number of positive cores) to Epstein criteria (OR: 6.041). Conclusions: Using a cutoff value of "1" for the number of positive biopsy cores and absence of biopsy PNI and HG-PIN findings can be more useful for improving the prediction model of the Epstein criteria in the 12-core biopsy scheme.
