Abstract
PURPOSE This retrospective study aimed to assess the correlation between preoperative sarcopenia and long-term oncologic outcomes in patients undergoing radical cystectomy for bladder cancer. METHODS We included 528 patients who underwent radical cystectomy for bladder cancer between 2000 and 2010 at Asan Medical Center, Seoul, Korea. Preoperative skeletal muscle mass was quantified by analyzing computed tomography images at the third lumbar vertebra. Sarcopenia was defined based on the skeletal muscle index. We evaluated various clinical and pathological factors to analyze the association between sarcopenia and long-term oncologic outcomes. RESULTS The median follow-up time was 104 months. Sarcopenia was identified in 37.9% of the patients. Although no significant differences were observed in traditional pathological factors between the sarcopenic and non-sarcopenic groups, sarcopenia was significantly associated with worse oncologic outcomes. Compared to the non-sarcopenic groups, the sarcopenic group had lower overall survival rates (52.0% vs. 67.1% at 5 years, 35.5% vs. 52.7% at 10 years) and higher cancer-specific mortality (63.3% vs. 74.3% at 5 years, 50.7% vs. 67.4% at 10 years). Multivariable Cox regression analysis demonstrated that sarcopenia was an independent predictor of cancer-specific survival (hazard ratio: 1.49, 95% confidence interval: 1.11-2.01, p = 0.008), alongside body mass index, tumor stage, lymph node metastasis, and lymphovascular invasion. CONCLUSION Sarcopenia was significantly associated with poor cancer-specific survival in patients undergoing radical cystectomy for bladder cancer. Detecting sarcopenia may assist in preoperative risk stratification and long-term management after radical cystectomy.

Abstract
PURPOSE The study aimed to investigate the impact of adjuvant chemotherapy on time to recurrence (TTR) and overall survival (OS) in patients with histologic variants of upper tract urothelial carcinoma (VUTUC) following radical nephroureterectomy (RNU). MATERIALS AND METHODS A retrospective review of 131 VUTUC patients' medical records, from a pool of 368 non-metastatic localized or locally advanced UTUC cases, treated at a single tertiary referral center between January 2011 and January 2021. The intervention was adjuvant chemotherapy administration post-RNU. TTR and OS were evaluated using Kaplan-Meier and Cox proportional hazard regression, covariates adjusted for age, postoperative GFR, history of neoadjuvant chemotherapy, T and N stage with stabilized inverse probability of treatment weighting (sIPTW). RESULTS The application of adjuvant chemotherapy showed a significant extension in TTR (P = .01), but no substantial impact on OS (P = .19) after sIPTW adjustment for covariates. Multivariate analysis revealed adjuvant chemotherapy, tumor size, and lymphovascular invasion as significant prognostic factors for TTR. In contrast, only tumor size and perineural invasion were significant for OS. Adjuvant chemotherapy reduced the progression risk in certain VUTUC subtypes (squamous or glandular/micropapillary), but not in sarcomatoid variants. CONCLUSIONS Adjuvant chemotherapy appears to improve TTR, albeit without a significant effect on OS, in nonmetastatic localized and locally advanced VUTUC patients post-RNU. While beneficial to some VUTUC subtypes, it did not yield significant advantages for sarcomatoid variants. Despite adjustments for known confounders, the study's findings may be subject to potential selection bias and unmeasured confounding factors.

Abstract
Non-gonococcal sexually transmitted infections (STIs) include chlamydia, syphilis, and chancroids. Chlamydia is the most common STI caused by Chlamydia trachomatis and is mainly transmitted through sexual intercourse or vertical transmission at birth. Although symptoms are mostly absent or mild, untreated chlamydial infections in females can lead to pelvic inflammatory disease, chronic pelvic pain, and infertility due to the narrowing of fallopian tubes. Syphilis is caused by Treponema pallidum and is divided into phase I, phase II, latent syphilis, and phase III. The incidence of syphilis, including congenital syphilis, has significantly increased in the United States in recent years. The chronic status of this disease can significantly increase morbidity and potentially affect almost all body organs, which, in rare cases, can lead to death. Additionally, untreated maternal syphilis can lead to fetal death and fatal congenital infections in newborns. Chancroid is an STI caused by Haemophilus ducreyi, and its prevalence is gradually decreasing in Korea and worldwide. The symptoms include shallow genital ulcers with suppurative granulomatous inflammation and tender inguinal lymphadenopathy. Chancroids can be differentiated from syphilitic chancres based on their appearance. In contrast to painless chancres, chancroids are painful. Ureaplasma urealyticum, Ureaplasma parvum, and Mycoplasma hominis are considered symbiotic bacteria. Infections caused by these bacteria are usually not considered STIs and do not require treatment unless they are suspected of being associated with infertility. This article presents the 2023 Korean STI guidelines for non-gonococcal bacterial infections.

Abstract
We investigated the therapeutic potential of bone marrow-derived mesenchymal stem cell-conditioned medium (BMSC-CM) on immortalized renal proximal tubule epithelial cells (RPTEC/ TERT1) in a fibrotic environment. To replicate the increased stiffness characteristic of kidneys in chronic kidney disease, we utilized polyacrylamide gel platforms. A stiff matrix was shown to increase α-smooth muscle actin (α-SMA) levels, indicating fibrogenic activation in RPTEC/TERT1 cells. Interestingly, treatment with BMSC-CM resulted in significant reductions in the levels of fibrotic markers (α-SMA and vimentin) and increases in the levels of the epithelial marker E-cadherin and aquaporin 7, particularly under stiff conditions. Furthermore, BMSC-CM modified microRNA (miRNA) expression and reduced oxidative stress levels in these cells. Our findings suggest that BMSC-CM can modulate cellular morphology, miRNA expression, and oxidative stress in RPTEC/TERT1 cells, highlighting its therapeutic potential in fibrotic kidney disease.

Abstract
PURPOSE This study aimed to evaluate the prognostic impact of the preoperative C-reactive protein to albumin ratio (CAR) on progression-free survival (PFS) and cancer-specific survival (CSS) in patients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU). METHODS A retrospective analysis was conducted using data from a single-center nephroureterectomy registry between January 2011 and December 2017. Participants were categorized into high and low CAR groups based on the optimal CAR cut-off value determined using the Youden index. The primary endpoint was PFS, the time from RNU to metastasis or disease recurrence. The secondary endpoint was CSS, the time from RNU to UTUC-related death. Median PFS and CSS were compared between the high and low CAR groups using Kaplan-Meier analysis and log-rank test. Multivariable Cox proportional hazard regression analysis was performed to assess the prognostic significance of CAR, adjusting for known prognostic factors. RESULTS We included 491 patients with UTUC in the analysis. The optimal CAR cut-off value was determined to be 0.036, which resulted in classifying 49.3% (242/491) of patients into the high CAR group. The high CAR group had older patients (69.8 vs. 67.4, p-value = 0.01), advanced T and N stages (p-value<0.001), high-grade tumor (p-value = 0.03), and a higher incidence of preoperative hydronephrosis (p-value < 0.01) than the low CAR group. The high CAR group demonstrated significantly inferior median PFS (78.3 vs. 100.3 months, p-value < 0.01) and CSS (73.2 vs. 96.1 months, p-value < 0.01) than the low CAR group. Moreover, high CAR independently increased the risk of disease progression (hazard ratio [HR]: 1.80, 95% confidence interval [CI]: 1.23-2.64, p < 0.01) and UTUC-related mortality (HR: 1.79, 95% CI: 1.15, p < 0.01). CONCLUSION Pre-operative CAR is independently associated with poor PFS and CSS in patients with UTUC undergoing RNU. Moreover, CAR may be an independent UTUC prognostic factor, offering a cost-effective and minimally invasive marker. However, further validation through large-scale, multi-center studies is necessary to confirm these findings and determine the optimal CAR cut-off value.

Abstract
Purpose To investigate p16 effects on diffusion image metrics and associations with tumor progression in patients with locally advanced head and neck cancers. Methods Diffusion images pretreatment and after 20 Gy (2wk) of RT were analyzed in patients with cT4/N3 p16+ oropharynx cancer (OPSCC) (N=51) and locoregionally advanced head and neck squamous cell carcinoma (LAHNSCC) (N=28), enrolled onto a prospective adaptive RT trial. Mean ADC values, subvolumes with ADC <1.2 um2/ms (TVLADC), and peak values of low (µL) and high (µH) components of ADC histograms in primary and total nodal gross tumor volumes were analyzed for prediction of freedom from local, distant, or any progression (FFLP, FFDP or FFLRDP) using multivariate Cox proportional-hazards model with clinical factors. P value with false discovery control <0.05 was considered as significant. Results With a mean follow up of 36 months, 18 of LAHNSCC patients and 16 of p16+ OPSCC patients had progression. After adjusting for p16, small µL and ADC values, and large TVLADC of primary tumors pre-RT were significantly associated with superior FFLRDP, FFLP and FFDP in the LAHNSCC (p<0.05), but no diffusion metrics were significant in p16+ oropharynx cancers. Post ad hoc analysis of the p16+ OPSCC only showed that large TVLADC of the total nodal burden pre-RT was significantly associated with inferior FFDP (p=0.05). Conclusion ADC metrics were associated with different progression patterns in the LAHNSCC and p16+ OPSCC, possibly explained by differences in cancer biology and morphology. A deep understanding of ADC metrics is warranted to establish imaging biomarkers for adaptive RT in HNSCC.

Abstract
PURPOSE To extend the indications of kidney-sparing surgery (KSS) for ureter cancer by comparing the oncological outcomes between patients with upper tract urothelial carcinoma (UTUC) who underwent radical nephroureterectomy (RNU) or KSS. METHODS We retrospectively reviewed 708 patients with UTUC who underwent RNU (N = 646) or KSS (N = 62) between 2011 and 2019 to analyze the oncologic outcomes and prognostic factors. Subgroup analyses were performed for patients with unifocal ureteral urothelial carcinoma (UC). RESULTS No significant difference was observed in the overall survival (OS) or cancer-specific survival (CSS) between RNU and KSS (distal ureterectomy with reimplantation (N = 33), ureterectomy with ileal ureter (N = 14), ureteroscopic tumor resection (N = 10), and ureterectomy with ureteroureterostomy (N = 5)). Among 269 (38.0%) patients with unifocal ureteral UC, 219 and 50 patients underwent RNU and KSS, respectively. OS and CSS were not significantly different between these two groups. Pathologic stage was a significant risk factor in multivariate analysis (hazard ratio = 2.621; p = 0.000). Among 646 RNU patients, 219 (33.9%) had unifocal ureteral UC, 40 (18.3%) with low-grade tumors. Among these, 13 (5.9%) patients with unifocal, low-grade and small (< 2 cm) tumors received nephroureterectomy. CONCLUSION Kidney-sparing surgery should be regarded as an important alternative to RNU for patients with unifocal ureteral UC thought to have noninvasive disease to preserve renal function and reduce overtreatment.

Abstract
BACKGROUND This study aimed to investigate the role of radical prostatectomy (RP) among clinical nodal metastasis prostate cancer and whether histological confirmation of lymph node metastasis through surgery can help with treatment. PATIENTS AND METHODS After excluding patients with distant metastatic prostate cancer or neoadjuvant androgen deprivation therapy, 42 patients with clinical nodal metastasis who underwent RP at our institution were included in the study. We classified them as having or not having pathological lymph node metastasis. Clinicopathologic data were analyzed in this retrospective chart review. Kaplan-Meier analysis was used to calculate the estimated castration-resistant prostate cancer (CRPC)-free survival, biochemical recurrence (BCR)-free survival, and cancer-specific survival (CSS). RESULTS There is no significant difference in age, presence of diabetes mellitus, hypertension, BCR time, CRPC time, overall survival, salvage RT rate, and initial prostate-specific antigen level between the two groups. However, there is a significant difference in the pathology N1 group in terms of pathological T stage, pathologic Gleason score, BCR rate, CRPC rate, and CSS. A multivariate Cox proportional hazard regression analysis was used to identify predictors of CRPC-free survival. Patients with pathological lymph node metastasis had a shorter CRPC-free survival [hazard ratio (HR) 4.87; 95% confidence interval (CI) 1.25-19.00, p = 0.02]. CONCLUSION Radical prostatectomy can confirm lymph node metastasis. Although pathologic diagnosis has no effect on time to BCR and CPRC, because it affects BCR rate, CRPC rate, and CSS, an accurate pathological diagnosis obtained through surgery is beneficial in the treatment of clinical lymph node metastasis prostate cancer.

Abstract
PURPOSE To evaluate the impact of preoperative renal impairment on the oncological outcomes of patients with urothelial carcinoma who underwent radical cystectomy. MATERIALS AND METHODS We retrospectively reviewed the medical records of patients with urothelial carcinoma who underwent radical cystectomy from 2004 to 2017. All patients who underwent preoperative 99mTc-diethylenetriaminepentaacetic acid renal scintigraphy (DTPA) were identified. We divided the patients into two groups according to their glomerular filtration rates (GFRs): GFR group 1, GFR≥90 mL/min/1.73 m²; GFR group 2, 60≤GFR<90 mL/min/1.73 m². We included 89 patients in GFR group 1 and 246 patients in GFR group 2 and compared the clinicopathological characteristics and oncological outcomes between the two groups. RESULTS The mean time required for recurrence was 125.5±8.0 months in GFR group 1 and 85.7±7.4 months in GFR group 2 (p=0.030). The mean cancer-specific survival was 131.7±7.8 months in GFR group 1 and 95.5±6.9 months in GFR group 2 (p=0.051). The mean overall survival was 123.3±8.1 months in GFR group 1 and 79.5±6.6 months in GFR group 2 (p=0.004). CONCLUSIONS Preoperative GFR values in the range of 60≤GFR<90 mL/min/1.73 m² are independent prognostic factors for poor recurrence-free survival, cancer-specific survival, and overall survival in patients after radical cystectomy compared with GFR values of ≥90 mL/min/1.73 m².

Abstract
Purpose This study aims to evaluate the association of serum lipid profile on prostate cancer (PC) risk and aggressiveness. Methods Men who underwent prostate biopsy between January 2005 and December 2015 were retrospectively analyzed. The association between lipid profile and the risk, stage, and Gleason grade group (GG) of the PC were investigated. Sensitivity analysis was conducted using univariate and multivariate quantile analysis for lipide profile on the risk and stage of PC. Results Of the 1740 study populations, 720 men (41.4%) were diagnosed as PC. From multivariate logistic regression analysis, age, prostate specific antigen, triglyceride (odds ratio (OR):1.05, confidence interval (CI):1.03-1.07, p-value<0.001) significantly increased PC risk, while total cholesterol (OR:0.96, CI:0.92-0.99, p-value=0.011) significantly decreased the PC risk. The increase of serum triglyceride increased the risk of both of locally advanced (OR:1.03, CI:1.00-1.07, p-value=0.025) and metastatic PC (OR:1.14, CI:1.04-1.25, p-value=0.004). The increase of serum triglyceride increased the risk of GG2-3 (OR:1.03, CI:1.00-1.06, p-value=0.027) and GG4-5 (OR:1.04, CI:1.01-1.08, p-value=0.027). Univariate quartile analysis founded serum triglyceride increasing risk of locally advanced disease than organ confined disease. (OR: 1.00, 1.25, 2.04, 4.57 for 1st, 2nd, 3rd and 4th quartile, p-value<0.001). Adjusted multivariate quartile analysis confirmed statistically significant increasing PC risk of triglyceride (OR: 1.00, 1.25, 2.04, 4.57 for 1st, 2nd, 3rd and 4th quartile, p-value<0.001). Conclusions This study findings suggested increased in triglyceride level increased the risk PC. Increased in triglyceride level also associated with aggressive presentation of PC, with higher stage and GG.

Abstract
We present a study on molecular-frame photoelectron angular distributions (MFPADs) of small molecules using circularly polarized synchrotron light. We find that the main forward-scattering peaks of the MFPADs are slightly tilted with respect to the molecular axis. This tilt angle is directly connected to the molecular bond length by a simple, universal formula. We apply the derived formula to several examples of MFPADs of C 1s and O 1s photoelectrons of CO, which have been measured experimentally or obtained by means of ab initio modeling. In addition, we discuss the influence of the back-scattering contribution that is superimposed over the analyzed forward-scattering peak in the case of homo-nuclear diatomic molecules such as N2.

Abstract
Immediate implant placement has the advantages of shortening the operation time, reducing the treatment cycle and cost. At present, this technology has been used widely, but the indications of immediate implantation are still limited. Here, a novel type of root analog implant (RAI) was manufactured by selective laser melting technology to address the limitation. Under optimized condition, RAIs were printed with the internal density of 99.73% and the uniform surface roughness of 11 μm (Sa). Besides, the deviation between RAI specimen and design models is controlled within 0.15 mm after optimizing scanning parameters. The substrate printed could promote human bone marrow stromal cell proliferation, spreading, and osteogenic differentiation. The bone-implant contact (BIC, 75% ± 7%) and bone volume/total volume (BV/TV, 74% ± 7%) of RAIs were significantly higher than that of conventional implants (BIC, 66% ± 5%; BV/TV, 62% ± 5%) in in vivo experiments. Further, customized abutments were designed for the RAIs, improving the masticatory ability of the beagle dogs after crown restoration. This study aims to design a personalized 2-stage RAI with compact structure and uniform roughness, in order to achieve better fracture resistance, initial osseointegration efficiency, and dispersed stress in immediate implantation. It provides a certain guiding value for standardizing the manufacture and clinical application of RAI in immediate implantation.

Abstract
PURPOSE We evaluated the performance of a new multi-degree-of-freedom articulating laparoscopic instrument, ArtiSential, and compared it with that of a straight-shaped instrument and the da Vinci surgical system, in renal surgery using porcine model. MATERIALS AND METHODS Nine female Yorkshire pigs were equally divided into three groups. The three groups were compared at each surgical step in terms of objective and subjective parameters. RESULTS The median operative times for renal pedicle clamping and ureter dissection were significantly shorter in ArtiSential group than robotic group (1.3 min vs. 4.7 min, p=0.002; 8.1 min vs. 11.1 min, p=0.015). The median operative time for bladder repair was significantly longer in ArtiSential group than robotic and straight-shaped groups (17.9 min vs. 5.5 min, p=0.002; 17.9 min vs. 9.3 min, p=0.026). There were no significant differences among groups in terms of blood loss or intraoperative complications. ArtiSential device was less useable for renorrhaphy (p=0.009) and bladder repair (p=0.002) compared to the robotic system. ArtiSential group was less accurate than robotic group in terms of tumor resection, renorrhaphy, and bladder repair. During ureter dissection, bladder cuff excision, and bladder repair, the surgeon experienced greater wrist discomfort but lesser back discomfort in ArtiSential group than robotic group. CONCLUSIONS For most steps, ArtiSential performed as well as robotic and straight-shaped instruments. The development of specialized surgical techniques for ArtiSential will maximize the advantages of these instruments.

Abstract
Background and Objectives We compared the efficacy and safety of human bone marrow-derived mesenchymal stem cells (hBMSC), delivered at different doses and via different injection routes in an animal model of chronic kidney disease. Methods and Results A total of ninety 12-week-old rats underwent 5/6 nephrectomy and randomized among nine groups: sham, renal artery control (RA-C), tail vein control (TV-C), renal artery low dose (RA-LD) (0.5×106 cells), renal artery moderate dose (RA-MD) (1.0×106 cells), renal artery high dose (RA-HD) (2.0×106 cells), tail vein low dose (TV-LD) (0.5×106 cells), tail vein moderate dose (TV-MD) (1.0×106 cells), and tail vein high dose (TV-HD) (2.0×106 cells). Renal function and mortality of rats were evaluated after hBMSC injection. Serum blood urea nitrogen was significantly lower in the TV-HD group at 2 weeks (p<0.01), 16 weeks (p<0.05), and 24 weeks (p<0.01) than in the TV-C group, as determined by one-way ANOVA. Serum creatinine was significantly lower in the TV-HD group at 24 weeks (p<0.05). At 8 weeks, creatinine clearance was significantly higher in the TV-MD and TV-HD groups (p<0.01, p<0.05) than in the TV-C group. In the safety evaluation, we observed no significant difference among the groups. Conclusions Our findings confirm the efficacy and safety of high dose (2×106 cells) injection of hBMSC via the tail vein.

Abstract
BACKGROUND Solo-surgery can be defined as a practice of a surgeon operating alone using a camera holder, without other surgical members except for a scrub nurse. This study was designed to evaluate the feasibility and safety of solo-surgeon pure laparoscopic donor nephrectomy. METHODS The study protocol was approved by the Institutional Review Board of Asan Medical Center, Seoul, Korea. The brief study protocol was registered on the Clinical Research Information Service site of the Korea Centers for Disease Control and Prevention. Candidates fulfilling all inclusion and exclusion criteria were enrolled in the clinical trial and underwent solo-surgeon pure laparoscopic donor nephrectomy. The feasibility was assessed by the proportion of subjects who could undergo solo-surgeon pure laparoscopic donor nephrectomy without difficulty. The perioperative complications were identified to assess the safety of solo-surgeon pure laparoscopic donor nephrectomy. RESULTS Of the 47 potential candidates from November 2018 to August 2019, 40 were enrolled in the clinical trial and seven excluded due to declining participation. The feasibility of solo-surgeon pure laparoscopic donor nephrectomy was 100%, without an occasion of any difficulty requiring conversion to the human assisted pure laparoscopic donor nephrectomy. Fourteen intraoperative complications occurred in 10 patients. The most common intraoperative complication was spleen injury. Two of three cases classified as the Satava classification grade II were due to the incomplete stapling of endoscopic stapler. Seventy-eight postoperative complications occurred in 34 patients. The most common postoperative complication was nausea/vomiting and followed by aspartate aminotransferase/alanine aminotransferase elevation. Most postoperative complication was independent of the solo-surgery itself. CONCLUSIONS Solo-surgeon pure laparoscopic donor nephrectomy using passive camera holder is technically feasible. In terms of safety, it is necessary to adjust the scope of surgery performed alone. Trial Registration CRIS, KCT0003458.

Abstract
A multiple receptor tyrosine kinase inhibitor, sunitinib, is a first-line therapy for clear cell renal cell carcinoma (CCRCC). Unfortunately, it has the major challenges of low initial response rate and resistance after about one year of treatment. Here we evaluated a microRNA (miRNA) and its target responsible for sunitinib resistance. Using miRNA profiling, we identified miR-96-5p upregulation in tumors from sunitinib-resistant CCRCC patients. By bioinformatic analysis, PTEN was selected as a potential target of miR-96-5p, which showed low levels in tumors from sunitinib-resistant CCRCC patients. Furthermore, PTEN and miR-96-5p levels were negatively correlated in a large The Cancer Genome Atlas kidney renal clear cell carcinoma cohort and high miR-96 and low PTEN represented poor prognosis in this cohort. Additionally, four-week sunitinib treatment increased miR-96-5p and decreased PTEN only in tumors from a sunitinib-resistant patient-derived xenograft model. We found a novel miR-96-5p binding site in the PTEN 3′ UTR and confirmed direct repression by luciferase reporter assay. Furthermore, we demonstrated that repression of PTEN by miR-96-5p increased cell proliferation and migration in sunitinib-treated cell lines. These results highlight the direct suppression of PTEN by miR-96-5p and that high miR-96-5p and low PTEN are partially responsible for sunitinib resistance and poor prognosis in CCRCC.

Abstract
Purpose Owing to the safety and cost effectiveness of conditioned medium (CM), its therapeutic effects have attracted significant attention from many researchers. To date, numerous studies have been conducted on CM; however, little has been done with regard to erectile dysfunction (ED). In this research, the potential of human mesenchymal stem cell-derived CM (MSC-CM) for the treatment of ED was investigated. Materials and Methods A high concentration of MSC-CM was prepared through 3D spheroid culturing with bone marrow-derived MSCs and cut-off filtering. The composition of CM was analyzed using biochemical assays, and the effect of the preparation process on the quality of CM was investigated. The therapeutic effects of MSC-CM were evaluated through animal studies using a cavernous nerve (CN) injury rat model. Results 3D spheroid culturing afforded a 278-fold increase in the total protein content of CM, as compared to that from 2D cultures; the protein concentration increased by 19 times on increasing the centrifugation time for cut-off filtering. Biochemical assays indicated that the CM contains various xlink:types of angiogenic, neurotrophic, and anti-inflammatory factors. Histological assay results showed that MSC-CM has angio- and neuro-trophic effect in a CN injury rat model in vivo, and these therapeutic effects appear in a dose-dependent manner. Conclusions The experimental results confirmed the therapeutic effect of MSC-CM in healing damaged cavernosal tissue and restoring erectile function. These results successfully demonstrated that MSC-CM has significant potential for the treatment of ED.

Abstract
Purpose To investigate the relationship between the width of spared neurovascular bundle (NVB) measured during robot-assisted laparoscopic prostatectomy and postoperative sexual outcomes. Methods Patients with localized prostate cancer with erectile hardness score ≥2 (N = 105) who underwent NVB-sparing robot-assisted laparoscopic prostatectomy were included. Patients were divided into three groups [first (Q1) vs. second and third (Q2-3) vs. fourth (Q4) quartile] according to width of spared NVB measured with a flexible ruler after prostate removal. Preoperative and postoperative sexual function was evaluated according to erectile hardness score and Expanded Prostate Cancer Index Composite questionnaires. Results The proportion of patients with postoperative erectile hardness score ≥2 at postoperative 6 months was as follows: 38.9% (Q1), 48.6% (Q2–3), and 83.3% (Q4) (P = 0.016). The preoperative/postoperative 6-month sexual function score was 40.7/16.9 (Q1), 48.1/19.0 (Q2–3), and 51.2/28.1 (Q4). Postoperative sexual function was significantly associated with preoperative sexual function in Q4 (P = 0.006) and Q2–3 (P = 0.030) but not in Q1. On multivariate analysis, the width of spared NVB was a significant predictor for postoperative 6-month erectile hardness score ≥2. Limitation includes selection bias and short follow-up duration. Conclusions Not only the performance but also the degree and quality of NVB sparing thought to be important for postoperative sexual function. Measurement of the width of NVB during surgery could be an easy intraoperative method for assessing the quality of NVB sparing.

Abstract
BACKGROUND We aimed to describe the effect of preoperative sarcopenia on oncologic outcomes of organ-confined renal cell carcinoma (RCC) after radical nephrectomy. PATIENTS AND METHODS A total of 632 patients with pT1-2 RCC who underwent radical nephrectomy between 2004 and 2014 were retrospectively analyzed. From preoperative computerized tomography (CT) scans, skeletal muscle index (SMI) was measured and gender-specific cutoff values at third lumbar vertebra of 52.4 cm2/m2 for men and 38.5 cm2/m2 for women were used to define sarcopenia. Survivals were compared and associations with sarcopenia were analyzed using Kaplan-Meier log rank tests and Cox proportional hazard regression models. Median follow-up was 83 months. RESULTS Of 632 patients, 268 (42.4%) were classified as sarcopenic. The sarcopenic group was more advanced in age (57 versus 53 years) and more predominantly male (71.3% versus 59.9%). Sarcopenic patients had lower body mass index (BMI, 23.0 versus 25.9 kg/m2), but there was no difference in tumor size, stage, or nuclear grade. Sarcopenia was associated with poorer overall survival (OS) and cancer-specific survival (CSS; OS 94.0% versus 82.1%; p < 0.001 and CSS 97.5% versus 91.8%; p < 0.001). On multivariate analysis, sarcopenia was an independent risk factor for all-cause mortality [hazard ratio (HR) 2.58; 95% CI 1.02-6.54] and cancer-specific mortality (HR 3.07; 95% CI 1.38-6.83). CONCLUSIONS Sarcopenia at diagnosis was an independent risk factor for all-cause and cancer-specific mortality after radical nephrectomy for pT1-2 RCC. These findings underscore the importance of assessing presence of sarcopenia for risk stratification even among surgical candidates.

Abstract
To compare the outcomes of patients with high-risk prostate cancer treated by primary radical prostatectomy (RP) and primary androgen deprivation therapy (ADT).The study included patients with high-risk or very high-risk prostate cancer. Patients treated with definitive radiation therapy and those with clinical N1 and M1 disease were excluded. The RP group was divided into sub-cohorts of patients treated with ADT and those who received ADT after biochemical recurrence post-RP. Cancer-specific survival (CSS) and overall survival (OS) were analyzed using the Kaplan-Meier method and the Cox proportional hazards model.The study analyzed 859 patients divided into the RP group (n = 654) and ADT group (n = 205). Castration-resistant prostate cancer was detected in 23 (3.5%) patients in the RP group and 43 (21.0%) patients in the ADT group. Mortality cases included 63 (9.6%) patients in the RP group and 91 (44.4%) patients in the ADT group. CSS (P = .0002) and OS (P < .0001) were significantly higher in the RP group than in the ADT group. In the sub-cohort, CSS did not differ significantly between the RP and ADT groups, whereas OS was significantly higher in the RP group than in the ADT group (P < .0001). In the multivariate analysis, primary ADT increased CSS (hazard ratio, 2.068; P = .0498) and OS (hazard ratio, 3.218; P < .0001) compared with RP.In clinically localized high-risk prostate cancer patients, primary RP was associated with better CSS and OS than primary ADT. Comprehensive counseling in this cohort of patients will help the selection of treatment.

Abstract
BACKGROUND AIMS The efficacy of phosphodiesterase type 5 inhibitors (PDE5Is), which are commonly used to treat erectile dysfunction (ED), is not satisfactory in patients with denervation of the cavernous nerve due to pelvic surgeries and diabetes mellitus (DM). Pre-clinical studies using bone marrow-derived mesenchymal stem cells (BMSCs) to treat ED have shown promising results. The authors conducted a phase 1 clinical trial with autologous BMSCs in patients with ED due to radical prostatectomy or DM. METHODS Ten patients (five with post-prostatectomy ED and five with DM-associated ED) who could not perform sexual activity despite taking the maximum dose of a PDE5I were enrolled. The brief clinical trial protocol was registered with the US National Institutes of Health on ClinicalTrials.gov (NCT02344849). The primary outcome was the safety of stem cell therapy, and the secondary outcome was the improvement of erectile function. RESULTS Of the 13 patients screened, 10 were registered in the clinical trial and received autologous BMSCs and nine completed the clinical trial. One patient with post-prostatectomy ED experienced two treatment-emergent adverse events (TEAEs) (pyrexia and back pain), and two patients with DM-associated ED experienced a total of five TEAEs (one case each of viral upper respiratory tract infection, prostatitis and pruritus and two cases of hyperglycemia). Of these patients, one with DM-associated ED experienced two serious TEAEs (two instances of hyperglycemia). All TEAEs were considered not to be related to autologous BMSC therapy. In addition, no clinical significance was identified related to other safety measures, such as laboratory tests and vital signs. The mean International Index of Erectile Function score increased significantly at 1 month versus baseline (24.9 versus 18.1, P = 0.0222). CONCLUSIONS This phase 1 clinical trial confirmed the safety and potential efficacy of autologous BMSC therapy in patients with ED. The authors' results need to be confirmed by a phase 2 clinical trial.

Abstract
OBJECTIVE Long non-coding ribonucleic acids X-inactive specific transcript (lncRNA XIST) is one lncRNAs which involved in multiple human cancers. However, the functions and potential molecular regulatory mechanisms of XIST/microRNA-137 (miR‑137) in pancreatic cancer (PC) still need to explore. PATIENTS AND METHODS PC tissues and cell lines were analyzed for XIST, miR-137 and Notch1 expressions through quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Nude mouse xenograft tumor assay was used to detect XIST effects on pancreatic tumorigenesis in vivo. Cell Counting Kit (CCK-8) assay was performed to detect PC cell proliferation. Dual-Luciferase reporter assay, qRT-PCR, RNA immunoprecipitation (RIP) and Western blot assays were applied to validate the target relationship of XIST, miR‑137 and Notch1. RESULTS Results demonstrated that XIST expression was increased in PC tissues and cells. XIST knockdown inhibited PC cell proliferation in vitro and also repressed the tumor growth in vivo. XIST directly interacted with miR-137 and negatively regulated its expression. Notch1 was identified as a target gene of miR-137 and XIST acted as a competitive endogenous RNA (ceRNA) to positively regulate Notch1 expression by suppressing miR-137. In addition, we detected miR-137 was negatively correlated with XIST and Notch1 respectively, and a positive correlation between Notch1 and XIST expression in PC tissues. Furthermore, Notch1 overexpression could offset the suppressing effect of XIST knockdown or miR-137 overexpression on cell proliferation. Therefore, XIST may play an important role in promoting cell proliferation through miR‑137 and Notch1 pathway in PC. CONCLUSIONS To sum up, these results proposed that XIST functioned as an endogenous sponge in promoting PC cell proliferation through competing for miR-137 to regulate Notch1 expression, and may provide more therapeutic targets for the patients with PC.

Abstract
PURPOSE We report our preliminary experience of using a hybrid ileal pouch, assessing oncologic outcomes, complications, voiding, and renal function. METHODS The study included 25 patients with bladder cancer treated with radical cystectomy with a hybrid ileal pouch with concomitant anti-refluxing and refluxing anastomosis, performed by a single surgeon. The patients were divided into two groups (first and last cases) according to the surgery date. Postoperative complications, separate renal function by renal scan, voiding function by uroflowmetry with residual urine, and oncologic outcomes were assessed. RESULTS The surgery duration was shorter in the last cases than the first cases. The voiding volume increased with time. There were 23 cases of grade 3 complication in 12 patients and one case of grade 4 complication (sepsis). In the first cases, ureterovesical stenosis occurred in five cases, whereas in the last cases, there were no cases of stenosis. In separate renal function, there was no difference between the left and right side or between the first and last cases. CONCLUSIONS The hybrid ileal pouch showed acceptable oncologic and functional outcomes and complications; therefore, it can be used according to the appropriate surgical situation with a relatively short bowel segment during neobladder construction.

Abstract
PURPOSE A Gleason score ≥ 8, metastatic tumor burden, and visceral metastasis are known prognostic factors for patients with metastatic hormone-sensitive prostate cancer (mHSPC). Notably, however, these indicators have not been fully validated internationally. We aimed in this present study to further analyze the factors that influence the prognosis of mHSPC. METHODS In this retrospective study, we identified 201 patients with newly diagnosed mHSPC between 2008 and 2014 and collected their clinical information. Cox proportional hazard regression models were used to identify prognostic factors in mHSPC. RESULTS The mean age of the patients at presentation was 70 years (interquartile range (IQR), 64-76 years). The prostate-specific antigen level was 141 ng/mL (IQR, 58.8-464.5 ng/mL). Of the 201 study patients, 191 (94.5%) and 131 (65.2%) cases had a biopsy Gleason score ≥ 8 and grade 5, respectively. More than 4 metastases were detected in 134 patients. Castration-resistant prostate cancer (CRPC) was evident in 160 cases after a mean follow-up period of 46.6 months. By multivariable analysis, a Gleason grade of 5 and bone metastasis lesion count ≥ 4 were found to be significantly associated with CRPC-free survival (hazard ratio (HR), 1.45; 95% confidence interval (CI), 1.01-2.07) and (HR 2.02; 95% CI 1.39-2.92) and overall survival (HR 1.67 95%; CI 1.16-2.42) and (HR 1.67 95%; CI 1.16-2.41). CONCLUSIONS Bone metastases ≥ 4 and a Gleason grade 5 are independent prognostic factors for CRPC-free and overall survival in mHSPC. A Gleason grade 5 is therefore a new prognostic indicator in mHSPC.

Abstract
OBJECTIVE To evaluate the efficacy and tolerability of a self-expandable covered metallic stent in patients with malignant prostatic obstruction secondary to prostate cancer (PC). METHODS We reviewed 22 cases of insertion of self-expandable covered metallic stents with barbs. Data were collected about PC status. Uroflowmetry variables, residual urine volume, International Prostate Symptom Score (IPSS), quality of life (QOL), and duration from stent insertion to removal were surveyed. These clinical parameters were compared before and after stent insertion. RESULTS The patients with PC showed a mean age of 75.5 ± 6.5 years and mean 5.1 ± 1.9 Charlson comorbidity index. The average flow rate (2.4 ± 1.9 vs 5.9 ± 2.4 mL/s, P = .005), peak flow rate (6.9 ± 6.2 vs 14.1 ± 5.5 mL/s, P = .003), flow time (54.6 ± 29.1 vs 23.6 ± 13.7 s, P = .002), residual urine volume (178.7 ± 195.5 vs 7.0 ± 7.1 mL, P = .004), IPSS (26.2 ± 8.1 vs 8.0 ± 6.5 points, P = .001), and QOL (4.7 ± 1.3 vs 2.4 ± 2.1 points, P = .030) improved between before and after stent insertion, respectively. Pain was the most common complication, but 60% of the patients were managed without any intervention. There were hematuria, urinary retention, urinary frequency, obstruction, and urinary incontinence. However, there was no urinary tract infection due to the stent. The median time to stent removal was 5.7 months. CONCLUSIONS The stent was maintained for about 6 months with improved objective and subjective outcomes. The patients with PC, who had a poor comorbidity index and advanced PC status showed a tolerable maintenance period. Self-expandable covered metallic stents can be used for PC patients with a short life expectancy and unsuitability for general anesthesia.

Abstract
We investigated the relationship between positive surgical margin (PSM)-related factors and biochemical recurrence (BCR) and the ability of intraoperative frozen sections to predict significant PSM in patients with prostate cancer. The study included 271 patients who underwent robot-assisted laparoscopic prostatectomy with bilateral nerve sparing and maximal urethral preservation. Intraoperative frozen sections of the periurethra, dorsal vein, and bladder neck were analyzed. The ability of PSM-related factors to predict BCR and significant PSM was assessed by logistic regression. Of 271 patients, 108 (39.9%) had PSM and 163 (60.1%) had negative margins. Pathologic Gleason score ≥8 (18.9% vs 7.5%, P = 0.015) and T stage ≥T3a (51.9% vs 24.6%, P < 0.001) were significantly more frequent in the PSM group. Multivariate analysis showed that Gleason pattern ≥4 (vs <4; hazard ratio: 4.386; P = 0.0004) was the only significant predictor of BCR in the PSM cohort. Periurethral frozen sections had a sensitivity of 83.3% and a specificity of 84.2% in detecting PSM with Gleason pattern ≥4. Multivariate analysis showed that membranous urethra length (odds ratio [OR]: 0.79, P = 0.0376) and extracapsular extension of the apex (OR: 4.58, P = 0.0226) on magnetic resonance imaging (MRI) and positive periurethral tissue (OR: 17.85, P < 0.0001) were associated with PSM of the apex. PSM with Gleason pattern ≥4 is significantly predictive of BCR. Intraoperative frozen sections of periurethral tissue can independently predict PSM, whereas sections of the bladder neck and dorsal vein could not. Pathologic examination of these samples may help predict significant PSM in patients undergoing robot-assisted laparoscopic prostatectomy with preservation of functional outcomes.

Abstract
Purpose We aimed to define the feasibility of the omission of routine insertion of a drain after pure laparoscopic donor nephrectomy (PLDN). We compared the outcomes between those with and without routine drain insertion. Materials and Methods From July 2014 to October 2018, 178 PLDN were consecutively performed by a single surgeon. Since October 2016, we stopped routine insertion of a drain after PLDN. Thus, the former 80 drained routinely were defined as the Drainage group and the latter 98 were defined as the Non-drainage group. One patient drained non-routinely in the Non-drainage group was excluded from the final analysis. Operative and convalescence parameters and intra- and postoperative complications were compared between the groups. Intra- and postoperative complications within 90 days of surgery were graded using the Satava and Clavien–Dindo classifications, respectively. Results Baseline characteristics were similar between the groups, except for concomitant surgery, American Society of Anesthesiologists score, and preoperative glomerular filtration rate. All operative and convalescence parameters were similar between the groups, except for postoperative glomerular filtration rate. The rates of overall intra- (22.5% versus 28.9%, p=0.337) and postoperative (62.5% versus 59.8%, p=0.713) complications were similar between the groups. The rates of potentially drain-related postoperative complications were also similar between the groups (36.3% versus 33.0%, p=0.650). Two patients per group suffered from major drain-related complications (2.5% versus 2.1%). Conclusions PLDN without routine drainage can be performed safely without an increase in postoperative morbidity.

Abstract
OBJECTIVE To investigate the usefulness of magnetic resonance imaging (MRI) with Prostate Imaging Reporting and Data System version 2 (PI-RADSV2) and clinical parameters in predicting seminal vesicle invasion (SVI). MATERIAL AND METHODS In this retrospective study, we identified 569 prostate cancer patients who underwent radical prostatectomy with MRI before surgery. SVI was interpreted with PI-RADSV2. Clinical parameters such as the prostate-specific antigen (PSA) and Gleason score (GS) were analyzed for the prediction of SVI. Logistic regression models and receiver operating characteristic (ROC) curves were used to evaluate SVI based on clinical parameters and MRI with PI-RADSV2. RESULTS The median age at presentation was 67 years (43-85 years). The median PSA level was 6.1 ng/mL (2.2-72.8 ng/mL). There were 113 patients with a biopsy GS of ≥ 8. A total of 34 patients (6.0%) were interpreted to have SVI by MRI of which 20 were true positive, and 52 patients (9.1%) had true SVI in the final pathologic analysis. In multivariable analysis, PSA (HR: 1.03, 95% CI: 1.00-1.07), biopsy GS ≥ 8 (HR: 4.14, 95% CI: 2.12-8.09), and MRI with PI-RADSV2 (HR: 14.67, 95% CI: 6.34-33.93) were significantly associated with pathologic SVI. The area under the curve of the model based on the clinical parameters PSA and GS plus MRI (0.862) was significantly larger than that of the model based on clinical parameters alone (0.777, p < 0.001). CONCLUSIONS MRI with PI-RADSV2 using the clinical parameters PSA and GS was effective in predicting SVI.

PURPOSE To define how much of renal function was determined by the preserved renal parenchymal volume and the ischemic insult during partial nephrectomy (PN) long after surgery. METHODS We analyzed the data of 530 consecutive patients who had undergone PN. For all patients, renal function was measured preoperatively and again at 3 postoperative months, then annually using 99mTc-diethylenetriaminepentaacetic acid renal scan. Perioperative variables potentially affecting the long-term ipsilateral glomerular filtration rate (GFR) and their time-varying contribution were assessed using a linear mixed model. RESULTS The mean preoperative ipsilateral GFR was 42.9 ml/min, which decreased by 27.3% at 3 months but began to recover thereafter continuing until 4 years (Δ% GFR at 1, 2, 3, 4, and 5 years: 22.3%, 18.5%, 14.7%, 10.0%, and 9.6%, respectively). Parenchymal volume reduction and ischemic time were significantly associated with postoperative ipsilateral GFR throughout observation period unvarying with time. Diabetes and proteinuria were not significant determinants of ipsilateral function at 3 months but became significant at 5 years. In multivariate analysis regarding recovery slope, volume reduction (β = -0.026, SE 0.006, P < 0.0001), preoperative ipsilateral GFR (β = -0.021, SE 0.007, P = 0.0012), proteinuria (β = -0.942, SE 0.372, P = 0.0116), and diabetes (β = -0.396, SE 0.197, P = 0.0447) were independently significant. CONCLUSION Ipsilateral renal function continued to improve until 5 years after PN. Parenchymal volume loss was the major determinant and its impact on long-term ipsilateral renal function remained constant while ischemic time affected early GFR reduction with its impact diminishing over time. Patient-related factors including diabetes and proteinuria gained significance over time and became independent determinants of recovery slope.

Abstract
The use of human mesenchymal stem cells (hMSCs) in clinical applications requires large-scale cell expansion prior to administration. However, the prolonged culture of hMSCs results in cellular senescence, impairing their proliferation and therapeutic potentials. To understand the role of microRNAs (miRNAs) in regulating cellular senescence in hMSCs, we globally depleted miRNAs by silencing the DiGeorge syndrome critical region 8 (DGCR8) gene, an essential component of miRNA biogenesis. DGCR8 knockdown hMSCs exhibited severe proliferation defects and senescence-associated alterations, including increased levels of reactive oxygen species (ROS). Transcriptomic analysis revealed that the antioxidant gene superoxide dismutase 2 (SOD2) was significantly downregulated in DGCR8 knockdown hMSCs. Moreover, we found that DGCR8 silencing in hMSCs resulted in hypermethylation in CpG islands upstream of SOD2. 5-aza-2'-deoxycytidine treatment restored SOD2 expression and ROS levels. We also found that these effects were dependent on the epigenetic regulator DNA methyltransferase 3 alpha (DNMT3A). Using computational and experimental approaches, we demonstrated that DNMT3A expression was regulated by miR-29a-3p and miR-30c-5p. Overexpression of miR-29a-3p and/or miR-30c-5p reduced ROS levels in DGCR8 knockdown hMSCs and rescued proliferation defects, mitochondrial dysfunction, and premature senescence. Our findings provide novel insights into hMSCs senescence regulation by the miR-29a-3p/miR-30c-5p/DNMT3A/SOD2 axis.

Abstract
OBJECTIVE To examine the association between Bacillus Calmette-Guerin (BCG) shortage and bladder cancer recurrence in high-risk non-muscle-invasive bladder cancer (NMIBC) patients. MATERIALS AND METHODS This retrospective study included 333 BCG-naive patients who underwent transurethral resection of bladder tumor for high-risk NMIBC between January 2014 and December 2017. The primary outcome was disease recurrence after operation. The secondary outcomes were trends in BCG shortages and differences in post-transurethral resection of bladder tumor intravesical treatments according to shortage. Multivariable Cox regression modeling was used to assess outcomes. RESULTS Among 333 patients (median age, 67 years; men, 270 [81.1%]), 94 (28.2%) experienced BCG shortage (BCG shortage group). Eleven episodes of BCG shortage occurred during the study period (median 10 days, range 2-97 days). Although we observed no statistically significant differences in clinical and pathological characteristics, there were significant differences in post-transurethral resection of bladder tumor intravesical treatments between the shortage and control groups (BCG: 28.7% vs. 68.1%, mitomycin/epirubicin: 27.7% vs. 1.7%, P < 0.001). The 3-year recurrence-free survival rate was significantly lower in the shortage group than that in the control group (38.0% vs. 60.2%, log-rank test, P = 0.010). In multivariable analysis, shortage (hazard ratio [HR] = 1.55, 95% confidence interval [CI] 1.09-2.21, P = 0.016) and tumor multiplicity (HR = 1.55, 95% CI 1.05-2.29, P = 0.028) were independent factors associated with the recurrence of bladder cancer. CONCLUSIONS High-risk NMIBC patients who experienced BCG shortage had a high risk of bladder cancer recurrence. Clinical trials of alternative treatment strategies and efforts to increase BCG supply are required.

Abstract
OBJECTIVE Long intergenic non-protein coding RNA 518 (LINC00518) was reported to be implicated and aberrantly expressed in multiple cancers. However, the pathogenic implications of LINC00518 in cervical cancer (CC) are still unclear. In this study, we focused on LINC00518 and investigated its expression pattern, clinical significance, and biological function in CC. PATIENTS AND METHODS The expression levels of LINC00518 in CC tissues and cell lines were determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR), and its clinical significance was assessed by statistical analysis. Cell apoptosis was determined by flow cytometry. The cell proliferation was evaluated by MTT assay and colony forming assay, and the migration and invasion were evaluated by wound healing assays and transwell assay. Western blot was used to detect the expression of relative proteins, including EMT markers and the JAK/STAT3 signaling markers. RESULTS We found that LINC00518 was upregulated in CC tissues and associated with International Federation of Gynaecology and Obstetrics (FIGO) stage, lymph node metastasis, depth of cervical invasion and poor survival of CC patients. Univariate and multivariate Cox regression analysis showed that LINC00518 played a significant role of independent prognostic markers in overall survival rates. Furthermore, knocking down LINC00518 expression significantly suppressed CC cell proliferation, migration and invasion, and induced apoptosis in vitro. Mechanistically, the downregulation of LINC00518 suppressed JAK/STAT3 activation and subsequently decreased N-Cadherin and Vimentin. CONCLUSIONS The present work first suggests that LINC00518 acts as an oncogene in CC via regulation of the JAK/STAT3 signaling pathway. In the future, LINC00518 may serve as a predictive biomarker and potential therapeutic target for CC patients.

Abstract
Purpose This study aimed to examine the causes of death in Korean patients who underwent radical prostatectomy for prostate cancer and investigate the relationship between comorbidity and mortality. Materials and Methods We conducted a retrospective multicenter cohort study including 4,064 consecutive patients who had prostate cancer and underwent radical prostatectomy between January 1998 and June 2013. The primary endpoint of this study was all-cause mortality, and the secondary endpoints were cancer-specific mortality (CSM) and other-cause mortality (OCM). Charlson comorbidity index (CCI) was calculated to assess the comorbidities of each patient. Results Of 4,064 patients, 446 (11.0%) died during follow-up. The cause of death was prostate cancer in 132 patients (29.6%), other cancers in 121 patients (27.1%), and vascular disease in 57 patients (12.8%) in our cohort. The overall 10-year CSM rate was lower than the OCM rate (4.6% vs. 10.5%). The 10-year CSM rate was lower than the OCM rate in low- to intermediate-risk group patients (1.2% vs. 10.6%), whereas they were similar in high-risk group patients (11.8% vs. 10.1%). In the multivariable analysis, CCI was independently associated with all-cause mortality after radical prostatectomy, regardless of age and pathologic features. Conclusion Death from prostate cancer was rare in Korean men who underwent radical prostatectomy. Clinicians should be aware of the possibility of overtreatment of low-risk prostate cancer in men with significant comorbidity. Our findings may help to facilitate counseling and plan management in this patient group.
