Purpose: We investigated the predictive factors for acute urinary retention (AUR) after transperineal template-guided mapping biopsy (TTMB). Materials and Methods: We retrospectively reviewed the records of 459 patients who had undergone TTMB between May 2017 and July 2020. Overall complications after TTMB were analyzed and categorized according to the Clavien-Dindo classification. Factors that were likely to affect AUR were analyzed using a logistic regression model. Results: Overall complications after TTMB were observed in 95 of the 459 patients (20.7%), of which AUR was the most commonly reported (17.4%, n=80), followed by hematuria (3.1%, n=14). Hematuria in one patient was categorized as Clavien-Dindo grade IIIa. All remaining complications were Clavien-Dindo grade I. In the multivariate regression model, age ≥65 (odds ratio, 2.44; 95% confidence interval [CI], 1.42–4.17; p=0.001), prostate volume ≥30 mL (odds ratio, 3.72; 95% CI, 1.19–11.62; p<0.02), and number of biopsy cores ≥30 (odds ratio, 2.89; 95% CI, 1.29–6.43; p=0.01) were identified as the predictors for AUR after TTMB. Conclusions: AUR is the most common complication after TTMB. Age ≥65 years, prostate volume ≥30 mL, and number of biopsy cores ≥30 were significant predictors of AUR following TTMB.

Purpose: To analyze and compare the results of robotic partial nephrectomy (RPN) at a single center with the previous large-scale studies in terms of perioperative and oncological outcomes. Materials and Methods: We retrospectively evaluated 1,013 cases of RPN in our center database from December 2008 to August 2018. Total 11 cases were excluded in final analysis. We evaluated perioperative outcomes as the Trifecta achievement, which is defined as no positive surgical margin (PSM), no perioperative complications greater than Clavien-Dindo classification I and a warm ischemia time of <25 minutes. In addition, we analyzed pathological and oncological outcomes; recurrence, metastasis, all-cause deaths, cancer-specific deaths, and 5-year survival rates. Results: In 1,002 cases, the Trifecta achievement was 61.1% (n=612). The postoperative complication was 18.4% (n=184) but most were grade 2 or less (14.9%, n=145). Ninety-three cases (9.28%) had benign and 907 cases (90.5%) had malignant pathologies. A local recurrence were 14 cases (1.54%) and distant metastasis were 20 cases (2.2%) during follow-up periods. All-cause death rate was 1.2% (n=11) and cancer-specific death rate was 0.2% (n=2). The median follow-up period was 39 months. A 5-year recurrence-free survival rate, cancer-specific survival rate, and overall survival rate were 95.2%, 99.7%, and 98.4%. Conclusions: In summary, our data shows comparable perioperative outcomes to other large-scale studies of RPN in terms of the Trifecta achievement with similar baseline characteristics. In terms of oncological outcomes, there was lower rate of PSM and similar recurrence free survival rate.

Purpose: To determine whether systemic inflammatory response (SIR), particularly platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR), has different prognostic role between patients with metastatic renal cell carcinoma (mRCC) receiving first-line tyrosine kinase inhibitors (TKI). Materials and Methods: We retrospectively reviewed 547 patients with mRCC who were diagnosed and treated with a first-line TKI between 2007 and 2015. The primary endpoint was overall survival (OS) and secondary endpoint was progression-free survival (PFS). We evaluated differences in survival outcomes according to SIR and identified predictors of OS and PFS. Results: In synchronous mRCC, patients with a higher PLR had significantly worse OS and PFS. Moreover, a higher NLR was also associated with both worse OS and PFS in these patients. However, PLR was not associated with either OS or PFS in metachronous mRCC patients. While metachronous mRCC patients with a higher NLR had worse OS compared to those with lower NLR, there was no difference in PFS according to the status of NLR. On multivariate analysis, PLR was identified as predictive factor for OS (hazard ratio [HR], 1.55) as well as PFS (HR, 1.39) in patients with synchronous mRCC, but not in patients with metachronous mRCC. Additionally, higher NLR was also remained as predictive factor of both OS (HR, 1.83) and PFS (HR, 1.57) in patients with synchronous mRCC. Conclusions: Our study indicates that simple biomarkers of SIR, particularly PLR and NLR, can be more useful predictors of survival outcomes in patients with synchronous mRCC rather than metachronous mRCC.

Purpose: The efficacy of nivolumab in metastatic renal cell carcinoma (mRCC) has been proven. However, the nivolumab experience in Korean patients with mRCC is still poorly reported. We report initial experiences with the efficacy and safety of nivolumab in patients with mRCC. Materials and Methods: We retrospectively reviewed records for 25 patients with mRCC who had failed targeted therapy and were treated by nivolumab (2 ㎎/㎏, every 2 weeks) at a single institution. The primary endpoint was objective response rate (ORR), and secondary endpoints were progression-free survival (PFS), safety profiles, and ORR in a programmed cell death receptor ligand 1 (PD-L1) expression subgroup. Results: The median age was 60 years and 16 patients (64%) were male. Objective responses were achieved in 8 patients (32.0%) (complete response, 1; partial response, 7). Median PFS was 3.0 months (95% confidence interval, 1.46–4.53). Treatment-related adverse events (AEs) of any grade were observed in 19 patients (76.0%) with 6 (24.0%) experiencing grade 3 to 4 treatment-related AEs. In subgroups by PD-L1 expression levels classified as 1% or greater and less than 1%, ORR was 50% and 0%, respectively. Conclusions: This study showed the efficacy and safety of initial experiences with nivolumab in Korean patients with mRCC who had failed targeted therapy. Our results were comparable to recent clinical trials on nivolumab in mRCC.

Purpose: There remains a lot of unmet need to increase understanding of node-positive (ypN+) muscle invasive bladder cancer (MIBC) after neoadjuvant chemotherapy and radical cystectomy to decide the appropriate therapeutics. Materials and Methods: In a retrospective study using the center cancer chemotherapy registry, we found 113 MIBC patients who were treated with neoadjuvant chemotherapy involving gemcitabine and cisplatin (GP) followed by radical cystectomy between 2010 and 2014. Disease-free survival (DFS) and overall survival (OS) were compared according to the pathologic node positivity (ypN- vs. ypN+). Among a total of 165 patients with MIBC who received neoadjuvant chemotherapy involving GP, 118 underwent radical cystectomy. In 46 patients with ypN+ disease, DFS and OS were evaluated according to administration of adjuvant GP. Results: After neoadjuvant chemotherapy and radical cystectomy, 41% of patients had ypN+ disease, which showed significantly shorter DFS (median, 7.4 months; 95% confidence interval [CI], 5.3–9.6 months) and OS (median, 20.0 months; 95% CI, 13.4–26.6 months) compared to those with ypN- disease. The patients with ypN+ disease had a high risk of recurrence or death, regardless of the administration of adjuvant chemotherapy or adjuvant regimen. Conclusions: Within the limitations of this retrospective study, MIBC patients with ypN+ disease despite neoadjuvant chemotherapy and radical cystectomy had a poor prognosis. Further studies involving novel, effective adjuvant treatment including immunotherapy agents are needed to reduce the high risk of recurrence or death in these patients.

Purpose: Partial nephrectomy has a similar oncologic outcome to radical nephrectomy while reducing cardiac and metabolic morbidity. However, previous studies reported that partial nephrectomy had been underutilized. The purpose of this study is to analyze trends in the use of partial nephrectomy in Korea and evaluate which individual factors and hospital factor influenced the operative approach. Materials and Methods: Using URO-PDS database, 11560 patients underwent nephrectomy for renal cell carcinoma between 2006 and 2010 were identified. International Classification of Disease (ICD-9) diagnosis codes were applied to target subject of interest. Logistic regression was applied to identify determinants of partial nephrectomy. Results: Over the study period, the proportion of partial nephrectomies has steadily increased from 9.4% in 2006 to 30.4% in 2010 (p<0.001). Deviation of utilization in partial nephrectomy has been observed based on the area (p<0.001) and type of surgery (p<0.001). Individual of younger age, as well as male, were more likely to be treated with partial nephrectomy (p<0.001 for each). Furthermore, Patient treated at hospitals with higher nephrectomy volume were more prone to be treated with partial nephrectomy (p<0.001 for each). Conclusions: Partial nephrectomies have been increasingly performed over the study period but are still underutilized.

Purpose: High Gleason score (8 to 10) is a poor prognostic factor regardless of treatment. Pathological downgrading sometimes occurs in high grade prostate cancer. The aim of this study is to evaluate treatment outcomes in patients with high grade prostate cancer on biopsy who were pathological downgrading after radical prostatectomy (RP). The impact on outcomes according to changes in the Gleason score after RP was evaluated. Materials and Methods: Of 3,236 men who underwent RP between September 1995 and December 2014, 541 patients with biopsy Gleason score 8 to 10 were retrospectively reviewed. We analyzed incidence and biochemical recurrence (BCR) free probability in this downgraded group according to the Gleason grade of cancer in the RP specimen. Results: Of 541 patients had a prostate biopsy Gleason score of 8 to 10. Two hundred ten patients showed pathological downgrading after RP (38.8%). Five-year BCR-free probability of patients who had Gleason score of 7 or less after RP was 46.8%. However, 5-year BCR-free probability of patients who remained Gleason scores 8 to 10 after RP was 28.5%. There was a significantly higher BCR-free probability in pathological downgrading group (p<0.001). On multivariate analysis, biopsy Gleason 8, lower PSA, clinical T2 stage was a significant predictor of downgrading. Conclusions: In this study, 38.8% of patients with high grade prostate cancer had a Gleason score of 7 or less in the RP specimen. Downgraded prostate cancer had more favorable treatment outcome. Serum PSA, clinical stage and biopsy Gleason score were the predictive factors for pathological downgrading.

Purpose: To evaluate the performance of combining prostate health index (PHI) and Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) for detection of clinically significant prostate cancer (csPCa). Materials and Methods: We retrospectively reviewed patients who underwent prostate biopsy for elevated prostate-specific antigen (PSA) ≥2.5 ng/mL and/or abnormal digital rectal examination. Serum markers for PSA, free PSA (fPSA), and [-2] proPSA (p2PSA) were measured, and PHI was calculated as ([p2PSA/fPSA]×[PSA]<SUP>1/2</SUP>). Multiparametric magnetic resonance imaging was performed using a 3.0T scanner and scored using PI-RADSv2. csPCa was defined as either grade group (GG) ≥2 disease or GG1 cancer detected in >2 cores or >50% of positive on biopsy. Univariable and multivariable logistic regression modelling, along with receiver-operating characteristic (ROC) curve analysis was used to predict the probability of csPCa. Results: Of the total 358 patients, 159 (44.4%) were diagnosed with csPCa. On univariable analysis, age, PSA density (PSAD), PHI and PI-RADSv2 were associated with csPCa. The area under the ROC curve (AUC) of baseline model incorporating age and PSAD was 0.663. The AUC of combining PHI and PI-RADSv2 to baseline model was higher than that of PHI alone to baseline model (0.884 vs. 0.807, p<0.0001) and PI-RADSv2 alone to baseline model (0.884 vs. 0.846, p=0.0002), respectively. If biopsy was restricted to patients with PI-RADS 5 as well as PI-RADS 3 or 4 and PHI ≥27, 36.0% of unnecessary biopsy could be avoided at the cost of missing 4.7% of csPCa. Conclusions: The combination of PHI and PI-RADSv2 to baseline model incorporating age and PSAD had higher accuracy for detection of csPCa compared with PHI or PI-RADSv2 alone.
