Abstract
PURPOSE To analyze the recurrence in patients with clinic stage T1 renal cell carcinoma (RCC) who were upstaged to stage T3a after partial nephrectomy (PN) using a new sub-classification criterion. METHODS A retrospective study of pathological characteristics was performed in patients who were upstaged to pT3a on the basis of fat invasion (FI). RESULTS After analyzing the pathological findings, we proposed the following new sub-classification criteria for pT3a RCC with FI: (1) renal tumor invades the pseudo-capsule and contacts the perinephric adipose tissue directly or the tumor protrudes into the perinephric adipose tissue like a tongue (Type A); and (2) tumor nodules are distributed in perinephric adipose tissues (Type B). A significant difference was observed in the recurrence rate between the two subtypes A and B. For Type B, the recurrence rate after radical nephrectomy (RN) and PN was 15.79% and 63.64%, respectively. The recurrence rates for Types A and B after PN were 11.11% and 63.64%, respectively. CONCLUSIONS T3a RCC with tumor nodules in perinephric adipose and/or an irregular tumor protruding into the adipose tissues lead to a higher recurrence rate. We recommend that T3a RCC be carefully analyzed and patients be treated on an individual basis.

Intensity-Modulated Radiation Therapy with Simultaneous Integrated Boost for Clinically Node-Positive Prostate Cancer: A Single-Institutional Retrospective Study. Cancers (Basel) 2021; 13:cancers13153868. [PMID: 34359768 PMCID: PMC8345592 DOI: 10.3390/cancers13153868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 07/23/2021] [Accepted: 07/27/2021] [Indexed: 11/17/2022] Open
Abstract
Simple Summary Recently, it has been shown that radiation therapy (RT) together with androgen-depletion therapy (ADT) might be more beneficial compared with ADT alone for clinically node-positive (cN1) prostate cancer. However, there are a limited number of studies that have addressed specific RT techniques and analyzed their clinical results. The present study was a retrospective analysis of cN1 prostate cancer patients treated with intensity-modulated radiation therapy with simultaneous integrated boost (SIB-IMRT), in addition to ADT, in our hospital. The present study suggests that ADT plus SIB-IMRT for cN1 prostate cancer treatment was safe and effective, was well tolerated, and had acceptable rates of late toxicity. Further prospective multicenter studies would be required to confirm the robustness of the present results. Abstract This study aimed to evaluate clinical outcomes and the toxicity of intensity-modulated radiation therapy with simultaneous integrated boost (SIB-IMRT) combined with androgen-deprivation therapy for clinically node-positive (cN1) prostate cancer. We retrospectively analyzed 97 patients with cN1 prostate cancer who received SIB-IMRT between June 2008 and October 2017 at our hospital. The prescribed dosages delivered to the prostate and seminal vesicle, elective node area, and residual lymph nodes were 69, 54, and 60 Gy in 30 fractions, respectively. Kaplan–Meier analysis was used to determine 5-year biochemical relapse-free survival (bRFS), relapse-free survival (RFS), overall survival (OS), and prostate cancer-specific survival (PCSS). Toxicity was evaluated using the Common Terminology Criteria for Adverse Events ver. 4.0. Over a median follow-up duration of 60 months, the 5-year bRFS, RFS, OS, and PCSS were 85.1%, 88.1%, 92.7% and 95.0%, respectively. Acute Grade 2 genito-urinary (GU) and gastro-intestinal (GI) toxicities were observed in 10.2% and 2.1%, respectively, with no grade ≥3 toxicities being detected. The cumulative incidence rates of 5-year Grade ≥2 late GU and GI toxicities were 4.7% and 7.4%, respectively, with no Grade 4 toxicities being detected. SIB-IMRT for cN1 prostate cancer demonstrated favorable 5-year outcomes with low incidences of toxicity.

Abstract
Advances in radiotherapy technology and technique over the last 3 decades have revolutionized radiation treatment options for genitourinary malignancies. The development of more focused and accurate radiation treatment has facilitated safe delivery of dose-escalated treatment that improves disease control and the development of shorter-duration hypofractionated treatment regimens that are more convenient for patients and improve access to treatment. The management of oligometastatic disease is evolving with ablative treatment of oligometastasis and the primary for select patients and shorter-duration palliative treatment regimens. Work is ongoing to personalize radiation treatment regimens for genitourinary malignancies based on molecular biomarkers.

Abstract
The Urologic Oncology Journal was founded 25 years ago and we reviewed the literature since that time in the area of urothelial cancer to see the progress and pitfalls we have made over this time period. A comprehensive literature search was conducted by the authors involved who are all actively involved in research, clinical trials, and treatment for urothelial cancer and the results were summarized over the past 25 years. The field of urothelial cancer has evolved tremendously in the last 25 years with the incorporation of molecular subtyping, novel imaging, immunotherapy, and robotic surgery. However, treatments such as BCG and radical cystectomy have remained steadfast over the last 25 years. Although we have a better understanding of the biology of bladder cancer, we still have a long way from being able to cure patients with bladder cancer and eliminate morbidity from treatments. Nevertheless, considerable progress has been made since the founding of the Urologic Oncology Journal 25 years ago.

Oncological outcomes of concomitant carcinoma in situ at radical cystectomy in pure urothelial bladder cancer and in histological variants. Urol Oncol 2021; 40:61.e9-61.e19. [PMID: 34334293 DOI: 10.1016/j.urolonc.2021.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 06/14/2021] [Accepted: 07/02/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION The presence of carcinoma in situ at transurethral resection is known to increase the risk of recurrence and progression to invasive disease. However, the evidence regarding the prognostic role of concomitant carcinoma in situ after radical cystectomy due to bladder cancer is controversial. Moreover, concomitant carcinoma in situ was found to be significantly associated with bladder histological variants. The aim of our study is to evaluate whether the presence of concomitant carcinoma in situ at radical cystectomy, impacts on recurrence and survival outcomes in pure urothelial bladder cancer, compared to histological variants. METHODS We evaluated 410 consecutive patients diagnosed with non-metastatic bladder cancer and treated with radical cystectomy at a single tertiary referral centre between January 2009 and May 2019. Patients were stratified according to the presence of carcinoma in situ. The Kaplan-Meier method was used to compare recurrence free, cancer specific and overall survival in pure urothelial and histological variants. Cox proportional hazards regression analyses model was used to predict recurrence, cancer specific and overall mortality in pure urothelial and histological variants bladder cancer, according to pathological stage. RESULTS Median age was 71 years. 340 patients (82%) were male. At a median follow-up of 32 months, disease recurrence, cancer specific mortality and overall mortality were, 37% (155 patients), 32.9% (135 patients) and 46.6% (191 patients), respectively. Concomitant and pure carcinoma in situ were found in 39% and 19% of radical cystectomy specimens, respectively. Concomitant carcinoma in situ was more frequent in patients with histological variants (50.9%) compared to pure urothelial bladder cancer (35.4%) (P-value <.001) and was associated with worst pathological features (lymphovascular invasion, lymph node involvement and non-organ confined disease). Recurrence free survival at Kaplan-Meyer analyses was significantly higher in patients with pure carcinoma in situ compared to those with concomitant or no carcinoma in situ (all P <.001), similarly for patients without carcinoma in situ compared with those with concomitant Cis (P =.02) at radical cystectomy. Cancer specific and overall survival were significantly higher in patients with pure carcinoma in situ compared to those with concomitant or no carcinoma in situ (all P <.001). Conversely no significant difference was found between patients without carcinoma in situ and with concomitant carcinoma in situ (P>0.1) at radical cystectomy Moreover, concomitant carcinoma in situ at radical cystectomy in histological variants is associated with higher free recurrence rate compared to the other groups. At multivariate Cox proportional hazards regression analyses the presence of carcinoma in situ at radical cystectomy was not associated with any survival effect or recurrence (all P > .05) in the overall population and when patients are stratified according to histology. However, concomitant carcinoma in situ represents an independent predictor of recurrence in the subgroup of patients with organ confined disease in case of urothelial bladder cancer and histological variants. CONCLUSION Concomitant carcinoma in situ should be considered a proxy of aggressiveness in bladder cancer after radical cystectomy. Based on its prognostic implications, concomitant carcinoma in situ should be considered for strict follow-up in patients with organ confined disease which may deserve adjuvant treatment both in pure urothelial bladder cancer and histological variants.

Abstract
BACKGROUND The Charlson Comorbidity Index is a poor predictor of mortality in men with castration resistant prostate cancer (CRPC). To improve this prediction, we created a comorbidity index based on filled prescriptions intended to be used in registry-based studies. MATERIALS AND METHODS In a population-based cohort of men with CPRC a drug comorbidity index (DCI-CRPC) was calculated based on prescriptions filled during a 365-day period before the date of CRPC diagnosis to predict mortality. Five risk categories for men with CRPC were defined based on PSA kinetics. Mortality rates were described by Kaplan-Meier curves. The predictive ability of the DCI-CRPC was compared in univariable models to that of the original DCI, derived from men in the general population, and to that of the Charlson Comorbidity Index. RESULTS In 1,885 men with CRPC the median overall survival ranged from 3.0 years (95% confidence interval [CI] 2.8 to 3.4) in the first tertile of the DCI-CRPC, to 1.0 year (95% CI 0.9 to 1.1) in the third tertile of the DCI-CRPC. The index had higher discriminative ability (C-index 0.667) than the Charlson Comorbidity Index (C-index 0.508). The discriminative ability of the DCI-CRPC was highest in the subgroup with least aggressive cancer (C-index 0.651) and lowest in men with most aggressive cancer (C-index 0.618). The performance of the DCI-CRPC was comparable to that of the original DCI. CONCLUSION Our newly created comorbidity index using filled prescriptions predicted death in men with CRPC better than the Charlson Comorbidity Index.

Abstract
PURPOSE To report long-term oncological outcomes after penile-sparing surgery (PSS) for superficial (Ta-Tis) or initially invasive (T1) penile cancer patients. METHODS We retrospectively analysed 85 patients with Ta/Tis/T1cN0cM0 penile cancer (1996-2018). All patients underwent PSS: circumcision, excision or laser ablation. First, Kaplan-Meier plots and multivariable Cox regression models tested tumor recurrence rates (any local/regional/metastatic). Second, Kaplan-Meier plots depicted progression-free survival (≥T2 or N1-3 or M1 disease). RESULTS Median (IQR) follow-up time was 64 (48-95) months. Overall, 48 (56%) patients experienced tumor recurrence. Median (IQR) time to tumor recurrence was 34 (7-52) months. Higher recurrence rates were observed for Tis (65%) and T1 (64%), compared to Ta (40%), but these differences were not significant on multivariable Cox regression analyses (HR:2.0 with 95% CI [0.9-5.1] and HR:2.2 with 95% CI [0.9-5.9], respectively). Moreover, higher recurrence rates were observed for G2-3 tumors (74%), compared to G1 (57%), but these differences were not significant on multivariable Cox regression analyses (HR:1.6; 95% CI [0.8-3.2]). During follow-up, 15 (17.5%) vs. 18 (21.2%) vs. 10 (11.5%) patients underwent 1 vs. 2 vs. ≥3 PSS. Moreover, 26 (30.6%) and 4 (4.7%) men were treated with glansectomy and partial/total penile amputation due to local progression, tumor size or patient preference. Additionally, 24 (28%) men underwent invasive nodal staging. Last, 22 (25.9%) patients experienced disease progression. Median (IQR) time to disease progression was 51 (31-82) months. CONCLUSION Patients treated with PSS for newly diagnosed superficial or initially invasive squamous cell carcinoma of the penis should be informed about the non-negligible risk of tumor recurrence and disease progression over time. In consequence, strict follow-up protocols are needed.

Prognostic relevance of ABO blood group system in non-metastatic renal cell carcinoma: An analysis of two independent European cohorts with long-term follow-up. Urol Oncol 2021; 39:736.e9-736.e16. [PMID: 34247906 DOI: 10.1016/j.urolonc.2021.06.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 06/02/2021] [Accepted: 06/08/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The ABO blood group system has been previously discussed as a risk factor to develop, as well as a prognostic factor in non-metastatic renal cell carcinoma (RCC). Controversial findings have been reported in different populations of RCC patients with rather short follow-up periods. In this study, we aimed to clarify the distribution and prognostic role of ABO blood groups upon 15 years of median follow-up in non-metastatic RCC patients. MATERIALS AND METHODS We evaluated the distribution and prognostic significance of ABO blood group system in two independent cohorts (n = 405 and n = 1473) of non-metastatic RCC patients, who underwent curative (partial or total) nephrectomy between 1998 and 2012 at two tertiary academic centers. Cancer-specific survival, metastasis-free survival, as well as overall survival (OS) were assessed using the Kaplan-Meier method, univariable- and multivariable Cox regression models were applied, respectively. RESULTS In the two cohorts, blood groups were not associated with any clinical endpoints (for cohort 2: Cancer-specific survival (HR = 1.233; 95%CI 0.998-1.523, P = 0.052), metastasis-free survival (HR = 1.161; 95%CI 0.952-1.416, P = 0.142) and OS (HR = 1.037; 95%CI 0.890-1.208, P = 0.641), respectively). Compared to 250.298 healthy blood-donors of the Styrian state, the distribution of blood groups was (624 (42.4%) versus 106.861 (42.7%) in group A, 191 (13%) vs. 34.164 (13.7%) in group B, 575 (39%) versus 93.579 (37.4%) in group O and 83 (5.6%) vs. 15.694 (6.3%), P = 0.467). CONCLUSION In this large study with the longest period of follow-up reported to date, the ABO blood group system could not be validated as a prognostic factor in predicting important clinical endpoints in non-metastatic RCC patients.

Abstract
Objectives: The objectives of the study were to compare the operative features, complication rates, functional, and pathological outcomes of laparoscopic partial nephrectomy (LPN) and robotic-assisted partial nephrectomy (RPN). Methods: The demographics, perioperative, and follow-up data of patients who underwent partial nephrectomy between January 2007 and April 2020 with minimally invasive methods were retrospectively analyzed. Patients with minimum 3 months follow-up were enrolled in the present study. Perioperative and pathological outcomes were compared between the patients underwent LPN and RPN. Results: A total of 85 patients (65 LPN and 20 RPN) were included in the present study. The mean patient age at the time of surgery was 56.31±10.48 years. Female-to-male ratio was 30/55. Patients in the RPN group had higher R.E.N.A.L. and PADUA scores (p=0.039 and p=0.030, respectively). Median warm ischemia time, median operation time, median intraoperative estimated blood loss, mean post-operative hemoglobin change, and median hospitalization time were similar between groups (p=0.133, p=0.753, p=0.079, p=0.882, and p=0.473, respectively). Artery-only clamping rate was significantly higher in RPN group (p=0.033). The cost of RPN was significantly greater than LPN (p<0.001). Transfusion rates, post-operative complication rates, percent of estimated glomerular filtration rate change at the last follow-up, and trifecta achievement were similar between the groups (p=0.622, p=0.238, p=0.428, and p=0.349, respectively). Conclusion: In this series, similar perioperative and functional outcomes were achieved by RPN compared to LPN in more complex renal masses.

Abstract
INTRODUCTION This study aimed to evaluate the chronologic changes in renal function after laparoscopic partial (LPN) or radical nephrectomy (LRN) in patients with clinical T1 renal cell carcinoma. METHODS In this retrospective study, patients with clinical stage T1 renal cell carcinoma who underwent LPN or LRN were divided into three groups, namely, LPN-A group including LPN patients with WIT ≤25 minutes, LPN-B group including LPN patients with WIT >25 minutes, and LRN group. Perioperative complications that occurred within 30 days after surgery were retrieved. All patients were followed-up every 3 months to evaluate the estimated glomerular filtration rate. The primary endpoint of this study was to assess the chronological changes in renal function after surgery. RESULTS A total of 153 patients were enrolled in this study. The change in estimated glomerular filtration rate between day 1 and 2 weeks after surgery was significantly lower in the LPN-B group than in the LPN-A group (p<0.005). Both LPN-A and -B groups achieved eGFR ≥90% 2 weeks after surgery. In addition, the estimated glomerular filtration rate decline from post-operative day 1 through 24 months in the LPN-A group or the LPN-B group was significantly smaller than that in the LRN group (P < 0.001, P < 0.001, respectively). CONCLUSION Our results demonstrate the efficacy and safety of LPN in patients with T1 renal cell carcinoma. Although complication rates were similar in both groups, post-operative renal function was not different between the LPN-A and -B groups.

Abstract
INTRODUCTION Bladder pleomorphic giant cell carcinoma is a rare and aggressive malignancy with a poor prognosis. There are no reports of immune checkpoint inhibitors for bladder pleomorphic giant cell carcinoma to date. CASE PRESENTATION A 72-year-old man presented with gross hematuria due to multiple bladder cancers. Despite transurethral bladder resection and intravesical injection of Bacillus Calmette-Guérin, bladder cancer recurred. Nineteen months later, he underwent total cystectomy. Pathological examination revealed bladder giant cell carcinoma. Twenty-eight months later, pembrolizumab was administered due to para-aortic lymph node metastasis. Forty-four months later, the lymph node metastasis disappeared, and pembrolizumab administration was terminated. Fifty-eight months later, the patient has remained in remission at the time of writing. CONCLUSION Immune checkpoint inhibitors manifest a therapeutic potential in bladder pleomorphic giant cell carcinoma.

Abstract
INTRODUCTION -The purpose was to propose an update of the French guidelines from the national committee ccAFU on upper tract urothelial carcinomas (UTUC). METHODS - A systematic Medline search was performed between 2018 and 2020, as regards diagnosis, options of treatment and follow-up of UTUC, to evaluate different references with levels of evidence. RESULTS - The diagnosis of this rare pathology is based on CT-scan acquisition during excretion and ureteroscopy with histological biopsies. Radical nephroureterectomy (RNU) remains the gold standard for surgical treatment, nevertheless a conservative endoscopic approach can be proposed for low risk lesion: unifocal tumor, possible complete resection and low grade and absence of invasion on CT-scan. Close monitoring with endoscopic follow-up (flexible ureteroscopy) in compliant patients is therefore necessary. After RNU, bladder instillation of chemotherapy is recommended to reduce risk of bladder recurrence. A systemic chemotherapy is recommended after RNU in pT2-T4 N0-3 M0 disease. CONCLUSION - These updated guidelines will contribute to increase the level of urological care for diagnosis and treatment for UTUC.

Abstract
Prostate cancer is a common malignancy, but only some tumors are lethal. Accurately identifying these tumors will improve clinical practice and instruct research. Aggressive cancers often have distinctive pathologies, including intraductal carcinoma of the prostate (IDC-P) and ductal adenocarcinoma. Here, we review the importance of these pathologies because they are often overlooked, especially in genomics and preclinical testing. Pathology, genomics, and patient-derived models show that IDC-P and ductal adenocarcinoma accompany multiple markers of poor prognosis. Consequently, "knowing what is growing" will help translate preclinical research to pinpoint and treat high-risk prostate cancer in the clinic.

High IL-22RA1 gene expression is associated with poor outcome in muscle invasive bladder cancer. Urol Oncol 2021; 39:499.e1-499.e8. [PMID: 34134925 DOI: 10.1016/j.urolonc.2021.05.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 05/03/2021] [Accepted: 05/05/2021] [Indexed: 01/05/2023]
Abstract
BACKGROUND The cell surface interleukin 22 (IL-22) receptor complex is mainly expressed in epithelial and tissue cells like pancreatitis cells. Recent studies described that IL-22R was overexpressed in malignant diseases and was associated with a poor overall survival (OS). The role of IL-22RA1 gene expression in muscle invasive bladder cancer (MIBC) has not been investigated, yet. OBJECTIVES The aim of this study was to analyze the role of IL-22RA1 gene expression in patients with MIBC. METHODS In a cohort of 114 patients with MIBC who underwent radical cystectomy, IL-22RA1 gene expression was analyzed with qRT-PCR and correlated with clinical parameters. Furthermore, Kaplan-Meier and Cox regression analysis were performed. For validation, an in silico dataset (TCGA 2017, n=407) was reanalyzed. RESULTS IL-22RA1 gene expression was independent of clinicopathological parameters like age (P=0.2681), T stage (P=0.2130), nodal status (P=0.3238) and lymph vascular invasion (LVI, P=0.5860) in patients with MIBC. A high expression of IL-22RA1 was associated with a shorter OS (P=0.0040) and disease-specific survival (P=0.0385). Furthermore, a shorter disease-free survival (DFS) was also associated with a high expression of IL-22RA1 (P=0.0102). In the multivariable analysis, IL-22RA1 expression was an independent prognostic predictors regarding OS (P=0.0096, HR=0.48). In the TCGA cohort, IL-22RA1 expression was independent regarding to OS and DFS. CONCLUSION A high IL-22RA1 gene expression was associated with worse outcome. Furthermore, IL-22RA1 represented an independent predictor regarding OS in our cohort and therefore might be used for risk stratification in patients with MIBC.

Abstract
OBJECTIVES To evaluate the impact of using clinical stage assessed by multiparametric magnetic resonance imaging (mpMRI) on the performance of two established nomograms for the prediction of pelvic lymph node involvement (LNI) in patients with prostate cancer. PATIENTS AND METHODS Patients undergoing robot-assisted extended pelvic lymph node dissection (ePLND) from 2015 to 2019 at three teaching hospitals were retrospectively evaluated. Risk of LNI was calculated four times for each patient, using clinical tumour stage (T-stage) assessed by digital rectal examination (DRE) and by mpMRI, in the Memorial Sloan Kettering Cancer Centre (MSKCC; 2018) and Briganti (2012) nomograms. Discrimination (area under the curve [AUC]), calibration, and the net benefit of these four strategies were assessed and compared. RESULTS A total of 1062 patients were included, of whom 301 (28%) had histologically proven LNI. Using DRE T-stage resulted in AUCs of 0.71 (95% confidence interval [CI] 0.70-0.72) for the MSKCC and 0.73 (95% CI 0.72-0.74) for the Briganti nomogram. Using mpMRI T-stage, the AUCs were 0.72 (95% CI 0.71-0.73) for the MSKCC and 0.75 (95% CI 0.74-0.76) for the Briganti nomogram. mpMRI T-stage resulted in equivalent calibration compared with DRE T-stage. Combined use of mpMRI T-stage and the Briganti 2012 nomogram was shown to be superior in terms of AUC, calibration, and net benefit. Use of mpMRI T-stage led to increased sensitivity for the detection of LNI for all risk thresholds in both models, countered by a decreased specificity, compared with DRE T-stage. CONCLUSION T-stage as assessed by mpMRI is an appropriate alternative for T-stage assessed by DRE to determine nomogram-based risk of LNI in patients with prostate cancer, and was associated with improved model performance of both the MSKCC 2018 and Briganti 2012 nomograms.

Abstract
Cystoscopic examination remains the gold standard technique for initial diagnosis of bladder cancer (BCa). Despite significant progress in enhanced cystoscopic techniques, blue light cystoscopy and narrow band imaging are the only ones well supported by high-level evidence and, if available, should be used during initial staging of BCa. Multiparametric MRI could be an important imaging tool in local staging of BCa. With ever-expanding targeted therapy and immunotherapy options in both muscle-invasive and non-muscle-invasive BCa, molecular subtyping could become an essential part of initial histologic staging in the near future.

Abstract
Signaling through chemokine receptor, C-X-C chemokine receptor type 4 (CXCR4) regulates essential processes in normal physiology, including embryogenesis, tissue repair, angiogenesis, and trafficking of immune cells. Tumors co-opt many of these fundamental processes to directly stimulate proliferation, invasion, and metastasis of cancer cells. CXCR4 signaling contributes to critical functions of stromal cells in cancer, including angiogenesis and multiple cell types in the tumor immune environment. Studies in animal models of several different types of cancers consistently demonstrate essential functions of CXCR4 in tumor initiation, local invasion, and metastasis to lymph nodes and distant organs. Data from animal models support clinical observations showing that integrated effects of CXCR4 on cancer and stromal cells correlate with metastasis and overall poor prognosis in >20 different human malignancies. Small molecules, Abs, and peptidic agents have shown anticancer efficacy in animal models, sparking ongoing efforts at clinical translation for cancer therapy. Investigators also are developing companion CXCR4-targeted imaging agents with potential to stratify patients for CXCR4-targeted therapy and monitor treatment efficacy. Here, pre-clinical studies demonstrating functions of CXCR4 in cancer are reviewed.

Abstract
Clinically node-positive prostate cancer is often found at the time of diagnosis by cross-sectional imaging and remains poorly understood. Advanced imaging modalities such as magnetic resonance imaging nanoparticles or positron emission tomography-based molecular imaging stand to rapidly change the field and hopefully will bring better diagnostic clarity. This will allow for prospective clinical trials using radiographic, clinical, or molecular parameters to establish who may benefit from both localized and systemic treatment intensification and who may avoid overtreatment. Recent advances in metastatic hormone-sensitive disease may offer clues, but direct studies for nodal disease patients remain.

Abstract
OBJECTIVE The number of cycles of platinum-based first-line chemotherapy associated with the maximum tumor response in patients with advanced urothelial carcinoma is not yet established. We investigated the association between the number of cycles and the maximum radiological response of first-line chemotherapy. METHODS We retrospectively evaluated 167 patients with advanced urothelial carcinoma treated with platinum-based first-line chemotherapy between May 2003 and December 2020. The primary outcome was estimating the number of cycles associated with the maximum radiological response and progression disease rate within the 6 cycles. The radiological response was evaluated by the RECIST v1.1. The secondary outcomes included the difference in radiological response rate and the impact on overall survival between the cisplatin-based and carboplatin-based regimens. RESULTS The maximum radiological response was -22% at Cycles 2. It was significantly decreased at Cycles 4 (-15%) compared with Cycles 2 (P < 0.001). The progression disease rate within the first 2, 4, and 6 cycles were 21% and 63%, and 84%, respectively. Radiological response was no significant difference between the cisplatin-based and carboplatin-based regimens. However, it was significantly decreased in the carboplatin-based regimen at Cycles 4 (-17%) compared with Cycles 2 (-22%; P = 0.004). Background-adjusted overall survival was not significantly different in between the cisplatin-based and carboplatin-based regimens (hazard rate 1.27; P = 0.337). CONCLUSION The maximum radiological response was -22% at Cycles 2. The radiological response was significantly different between Cycle 2 and 4. More than half of patients had disease progression within the first 4 cycles.

Abstract
Multilocular cystic nephroma is a rare benign kidney tumor, which is typically characterized by a unilateral, multicystic renal mass without solid elements. Cystic nephroma has a bimodal distribution and two-thirds of tumors involve children aged between 3 months and 2 years, with male predominance; a second peak affects the age group >30 years old, in which females are predominantly affected. The incidence rate for this rare tumor in patients aged 5-30 years is only 5%. The present study reports a case of a 31-year-old woman affected by a multilocular cystic nephroma in the upper pole of the right kidney, with direct tumor extension into the renal pelvis through a calyx. After a partial nephrectomy on the patient, the pathological examination confirmed a multilocular cystic nephroma in the right renal specimens.

Accuracy of Transurethral Resection of the Bladder in Detecting Variant Histology of Bladder Cancer Compared with Radical Cystectomy. Eur Urol Focus 2021; 8:457-464. [PMID: 33867307 DOI: 10.1016/j.euf.2021.04.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Revised: 03/04/2021] [Accepted: 04/04/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Correct identification of variant histologies (VHs) of bladder cancer (BCa) at transurethral resection of the bladder (TURB) could drive the subsequent treatment. OBJECTIVE To evaluate the concordance in detecting VHs between TURB and radical cystectomy (RC) specimens in BCa patients. DESIGN, SETTING, AND PARTICIPANTS We retrospectively analyzed 1881 BCa patients who underwent TURB and subsequent RC at seven tertiary care centers between 1980 and 2018. VHs were classified as sarcomatoid, lymphoepithelioma-like, neuroendocrine, squamous, micropapillary, glandular, adenocarcinoma, nested, and other variants. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Concordance between TURB and RC was defined as the ability to achieve histological subtypes at TURB confirmed at RC specimen, and was expressed according to Cohen's kappa coefficient. RESULTS AND LIMITATIONS Of the patients, 14.6% and 21% were diagnosed with VH at TURB and RC specimens, respectively. The most common VHs at TURB were squamous, neuroendocrine, and micropapillary carcinoma (5.2%, 1.5%, and 1.5%, respectively). At RC, the most frequent VHs were squamous, micropapillary, and sarcomatoid carcinoma (7.2%, 3.0%, and 2.7%, respectively). The overall concordance in detecting VH was defined as slight concordance (coefficient: 0.18). Moderate concordance was found for neuroendocrine, adenocarcinoma, and squamous carcinoma (coefficient: 0.49, 0.47, and 0.41, respectively). Micropapillary, glandular, and other variants showed slight concordance (coefficient: 0.05, 0.17, and 0.12, respectively), while nested and sarcomatoid carcinoma showed fair concordance (coefficient: 0.32 and 0.26, respectively). Results may be limited by the absence of centralized pathological analysis. CONCLUSIONS A non-negligible percentage of patients were diagnosed with VH at both TURB and RC. TURB showed relatively low accuracy, ranging from poor to moderate, in detecting VHs. Our study underlines the need of additional diagnostic tools in order to identify VHs properly at precystectomy time and to improve patient survival outcomes. PATIENT SUMMARY In this report, we underlined the low accuracy of transurethral resection of the bladder in detecting variant histologies and the need for additional diagnostic tools.

Neuropilin-2 and Its Transcript Variants Correlate with Clinical Outcome in Bladder Cancer. Genes (Basel) 2021; 12:genes12040550.

Abstract
Urothelial bladder cancer ranks among the 10 most frequently diagnosed cancers worldwide. In our previous study, the transmembrane protein neuropilin-2 (NRP2) emerged as a predictive marker in patients with bladder cancer. NRP2 consists of several splice variants; the most abundant of these, NRP2a and NRP2b, are reported to have different biological functions in lung cancer progression. For other cancer types, there are no published data on the role of these transcript variants in cancer progression and the clinical outcome. Here, we correlate NRP2 and its two most abundant transcript variants, NRP2A and NRP2B, with the clinical outcome using available genomic data with subsequent validation in our own cohort of patients with muscle-invasive bladder cancer. In addition to NRP2, NRP1 and the NRP ligands PDGFC and PDGFD were studied. Only NRP2A emerged as an independent prognostic marker for shorter cancer-specific survival in muscle-invasive bladder cancer in our cohort of 102 patients who underwent radical cystectomy between 2008 and 2014 with a median follow-up time of 82 months. Additionally, we demonstrate that high messenger expression of NRP2, NRP1, PDGFC and PDGFD associates with a more aggressive disease (i.e., a high T stage, positive lymph node status and reduced survival).

Abstract
Simple Summary Testicular germ cell tumors (GCTs) are the most common malignancies in young males. The current treatment regimens are usually highly effective and curative. Nevertheless, a portion of patients presents with recurrence or succumbs due to the disease. There is an undoubtful necessity to investigate new prognostic markers to stratify the risk of such events. The current study aimed to evaluate the prognostic significance of markers of the tumor microenvironment and systemic inflammation markers in GCTs. We found that low expression of immune checkpoint proteins VISTA (V-domain Ig suppressor of T cell activation) and PD-L1 (programmed death-ligand 1) on tumor-associated immune cells and elevated inflammatory marker platelet-to-lymphocyte ratio are associated with a higher risk of events in testicular GCTs. It indicates a role of both local anti-tumor immune response and systemic inflammation in these tumors. Abstract In the current study, we aimed to investigate whether expression of immune checkpoint proteins (V-domain Ig suppressor of T cell activation (VISTA) and programmed death-ligand 1 (PD-L1)) and markers of systemic inflammation could predict progression/relapse and death in the cohort of 180 patients with testicular germ-cell tumors (GCTs). Expression of PD-L1 and VISTA was assessed by immunohistochemistry utilizing tissue microarrays. To estimate systemic inflammation neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) were calculated. We found high PD-L1 and VISTA expression on tumor-associated immune cells (TAICs) in 89 (49.44%) and 63 (37.22%) of GCTs, respectively, whereas tumor cells besides trophoblastic elements were almost uniformly negative. High PD-L1 was associated with seminomatous histology and lower stage. Relapses in stage I patients occurred predominantly in cases with low numbers of PD-L1 and VISTA-expressing TAICs. In stage II/III disease, the combination of low VISTA-expressing TAICs and high PLR was identified as predictor of shorter event-free survival (HR 4.10; 1.48–11.36, p = 0.006) and overall survival (HR 15.56, 95% CI 1.78–135.51, p = 0.001) independently of tumor histology and location of metastases. We demonstrated that the assessment of immune checkpoint proteins on TAICs may serve as a valuable prognostic factor in patients with high-risk testicular GCTs. Further study is warranted to explore the predictive utility of these biomarkers in GCTs.

Pathological predictors of metastatic disease in testicular non-seminomatous germ cell tumors: which tumor-node-metastasis staging system? Mod Pathol 2021; 34:834-841. [PMID: 33319858 DOI: 10.1038/s41379-020-00717-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 11/03/2020] [Accepted: 11/06/2020] [Indexed: 11/08/2022]
Abstract
Pathological risk factors for metastatic disease in patients with testicular non-seminomatous germ cell tumors are debated. The tumor-node-metastasis (TNM) classification eighth edition for testicular cancers includes divergent versions, by the International Union Against Cancer (UICC) and by the American Joint Committee for cancer (AJCC). We investigated pathological predictors of metastatic disease at presentation in 219 non-seminomatous germ cell tumors with reference to both classifications. Age, tumor size, percentage of embryonal carcinoma, lymphovascular invasion, invasion of stromal rete testis, hilar soft tissue, epididymis, spermatic cord, and tunica vaginalis, as well as tumor at spermatic cord margin, were assessed and correlated with clinical stage at presentation. Of the 219 NSGCT cases, 151 (69%) were clinical stage I, 68 (31%) were clinical stage II/III. On univariate analysis, tumor size (P = 0.028), percentage of embryonal carcinoma (P = 0.004), lymphovascular invasion (P = 0.001), stromal rete testis invasion (P = 0.001), hilar soft tissue invasion (P = 0.010), epididymis invasion (P = 0.010), direct spermatic cord invasion (P = 0.001), and tumor at spermatic cord margin ((P = 0.009) were associated with higher clinical stage. On multivariate analysis, lymphovascular invasion (P = 0.003), tumor size (P = 0.005), percentage of embryonal carcinoma (P = 0.005), stromal rete testis invasion (P = 0.008) remained significant. A tumor size of 6 cm and an embryonal carcinoma percentage of 70% were the significant cut-off values. We conclude that in addition to lymphovascular invasion, stromal rete testis invasion, tumor size, and embryonal carcinoma percentage are strong predictors of metastatic disease at presentation and their inclusion should be considered in any future TNM revision. Further, our results support the changes in the AJCC TNM eighth edition as invasion of the epididymis and hilar soft tissue were both univariately significant.

Abstract
Introduction: We evaluated incidence ofprostate-specific antigen (PSA) positivity (>4ng/mL) and cancer detection rate on prostate biopsy in two populations of men, one undergoing opportunistic testing for lower urinary tract symptoms and another during routine health checks. Methods: Data regarding PSA screening, rectal examination (RE), transrectal ultrasound-guided biopsy, clinical stage, and risk assessment grouping according to NCCN guidelines were studied. Group A included patients with lower urinary tract symptoms (LUTS) (opportunistic screening) at SGPGIMS, Lucknow and Group B included healthy men who had executive health check-up with PSA testing at Medanta the Medicity, Gurugram. Results: PSA positivity rate in 9906 symptomatic men for LUTS (Group A) and 24919 healthy men (Group B) was 28.4% and 3% respectively. In group A, PSA positivity rate was 28.4% but only around half of all men with an indication underwent a biopsy. Among men with PSA of 4–10 ng/mL, cancer was detected in 93 of 241 who underwent a biopsy (38.5%). In Group B, only 69 men (9.3% of those with an elevated PSA) underwent a prostate biopsy, of which 38/57 (with PSA of 4–10 had cancer. In Group A, the cancers was metastatic in 61.5% men, while none in-Group B had metastatic disease. Conclusion: Opportunistic screening and executive health check with PSA identifies a significant number of men with PSA positivity and may help decrease the proportion of men diagnosed in metastatic prostate cancer.

Abstract
V-domain immunoglobulin suppressor of T cell activation (VISTA) is an immune checkpoint molecule expressed in hematopoietic cells, granulocytes, macrophages, and monocytes. However, few studies to date have investigated VISTA expression, especially its clinical utility, in bladder cancer. The present retrospective study aimed to examine VISTA, programmed death ligand-1 (PD-L1), and CD45 expression by immunohistochemical and immunofluorescence staining of archived pathological tissue samples from 159 patients with primary bladder cancer. The correlation between VISTA expression in immune cells (ICs) and clinicopathologic variables including PD-L1 expression in ICs was examined. Briefly, the rates of VISTA-positive ICs and VISTA-positive tumor cells were 67.9% (108/159) and 30.8% (49/159), respectively. The VISTA expression in ICs of patients with bladder cancer, including those with non-muscle-invasive bladder cancer (NMIBC), was positively correlated with tumor stage, grade, size, and multiplicity. The VISTA expression in ICs was stronger in bladder cancer cases with PD-L1-positive ICs than in those with PD-L1-negative ICs (p < 0.001). The mean intravesical recurrence-free survival was shorter in NMIBC cases with VISTA-positive ICs than in those with VISTA-negative ICs (34.0 vs 39.9 months, p = 0.03, log-rank test). In this first study to investigate VISTA expression in bladder cancer, these results implicate VISTA as a potential immunotherapeutic target and immunologic biomarker in bladder cancer.

Abstract
Although microRNAs are described as promising biomarkers in many tumor types, little is known about their role in PSCC. Thus, we attempted to identify miRNAs involved in tumor development and metastasis in distinct histological subtypes considering the impact of HPV infection. In a first step, microarray analyses were performed on RNA from formalin-fixed, paraffin-embedded tumor (22), and normal (8) tissue samples. Microarray data were validated for selected miRNAs by qRT-PCR on an enlarged cohort, including 27 tumor and 18 normal tissues. We found 876 significantly differentially expressed miRNAs (p ≤ 0.01) between HPV-positive and HPV-negative tumor samples by microarray analysis. Although no significant differences were detected between normal and tumor tissue in the whole cohort, specific expression patterns occurred in distinct histological subtypes, such as HPV-negative usual PSCC (95 differentially expressed miRNAs, p ≤ 0.05) and HPV-positive basaloid/warty subtypes (247 differentially expressed miRNAs, p ≤ 0.05). Selected miRNAs were confirmed by qRT-PCR. Furthermore, microarray data revealed 118 miRNAs (p ≤ 0.01) that were significantly differentially expressed in metastatic versus non-metastatic usual PSCC. The lower expression levels for miR-137 and miR-328-3p in metastatic usual PSCC were validated by qRT-PCR. The results of this study confirmed that specific miRNAs could serve as potential diagnostic and prognostic markers in single PSCC subtypes and are associated with HPV-dependent pathways.

Abstract
Matrix metalloproteinase-7 (MMP-7) is a small proteolytic enzyme that secretes zinc and calcium endopeptidases. It can degrade a variety of extracellular matrix substrates and other substrates and plays important regulatory roles in many human pathophysiological processes. Since its discovery, MMP-7 has been recognized as a regulatory protein in wound healing, bone growth, and remodeling. Later, MMP-7 was reported to regulate the occurrence and development of cancers and mediate the proliferation, differentiation, metastasis, and invasion of several types of cancer cells via various mechanisms. Thus, matrix metalloproteinase-7 may be a promising tumor biomarker and therapeutic target. The expression of MMP-7 correlates with the clinical characteristics of cancer patients, and its expression profile is a new diagnostic and prognostic biomarker for a variety of human diseases. Hence, manipulating the expression or function of MMP-7 may be a potential treatment strategy for different diseases including cancers. This review summarizes the role played by MMP-7 in carcinogenesis of several human cancers, underlying mechanisms, and its clinical significance of the occurrence and development of cancers.

Abstract
Clinically, patients with urothelial carcinoma of the bladder (UCB) with tumor metastasis are incurable. To find new therapeutic strategies, the mechanisms underlying UCB invasion and metastasis should be further investigated. In this study, zinc finger and homeobox 3 (ZHX3) was first screened as a critical oncogenic factor associated with poor prognosis in a UCB dataset from The Cancer Genome Atlas (TCGA). These results were also confirmed in a large cohort of clinical UCB clinical samples. Next, we found that ZHX3 could promote the migration and invasion capacities of UCB cells both in vitro and in vivo. Mechanistically, coimmunoprecipitation (coIP) and mass spectrometry (MS) analysis indicated that ZHX3 was a target of tripartite motif 21 (TRIM21), which mediates its ubiquitination, and subsequent degradation. Notably, RNA‐seq analysis showed that ZHX3 repressed the expression of regulator of G protein signaling 2 (RGS2). Generally, our results suggest that ZHX3 plays an oncogenic role in UCB pathogenesis and might serve as a novel therapeutic target for UCB.

Abstract
OBJECTIVES To assess the impact of the presence of bland thrombus (BT) on prognosis of patients treated with resection of renal cell carcinoma (RCC) with inferior vena cava tumor thrombus (IVCTT). MATERIALS AND METHODS The medical records of a total of 145 consecutive postsurgical RCC patients with level I-IV IVCTT were reviewed from January 2008 to August 2018. Associations of BT with clinicopathological variables were estimated by chi-square test or Student's t-test. Kaplan-Meier method and multivariate Cox proportional hazard model were used. The eighth TNM staging system, "Spiess PE" model, University of California at Los Angeles Integrated Staging System and Stage, Size, Grade, and Necrosis (SSIGN) score were selected to assess whether BT could improve their predictive abilities. RESULTS BT was observed in 34 (23.4%) patients and was significantly associated with increased levels of IVCTT (P = 0.004) and invasion of IVC wall (P = 0.030). Multivariable Cox analyses revealed that tumor grade, T stage, M stage, tumor thrombus consistency and BT were independent risk factors for both progression-free survival and overall survival. The concordance indexes ranged from a low of 0.652 in TNM to a high of 0.731 in SSIGN, and integrating BT into each base model led to an increased predictive accuracies of 6.2% for TNM (P = 0.025), 4.0% for "Spiess PE" model (P = 0.069), 2.1% for University of California at Los Angeles Integrated Staging System (P = 0.149) and 1.2% for SSIGN (P = 0.290), respectively. CONCLUSIONS Presence of BT was independently associated with survival in postsurgical patients with RCC-IVCTT. Routine consideration of BT as an adjunct to TNM staging system may be suggested.

Clinical advantages of robot-assisted partial nephrectomy versus laparoscopic partial nephrectomy in terms of global and split renal functions: A propensity score-matched comparative analysis. Int J Urol 2021; 28:630-636. [PMID: 33660374 DOI: 10.1111/iju.14525] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 01/17/2021] [Indexed: 01/20/2023]
Abstract
OBJECTIVES To identify predictors of renal function preservation, and to compare the global and split renal function outcomes of robot-assisted partial nephrectomy and laparoscopic partial nephrectomy. METHODS Demographic, operative and pathological data, as well as renal function outcomes, of 251 patients who underwent laparoscopic (n = 104) and robot-assisted (n = 147) partial nephrectomy between 2008 and 2018 were retrospectively analyzed. Propensity score matching (1:1) was carried out to adjust for potential baseline confounders. Functional outcomes were assessed based on the estimated glomerular filtration rate and dynamic renal scintigraphy (using 99m Tc-mercaptoacetyltriglycine), including renal volumetric analysis. RESULTS A total of 98 patients were allocated to each partial nephrectomy group. Ischemic (laparoscopic vs robot-assisted partial nephrectomy: 29 vs 15 min, P < 0.001) and operative times (181 vs 100 min, P < 0.001) were shorter in robot-assisted partial nephrectomy. The preservation ratio of global renal function at 3 months (88.3% vs 91.4%, P = 0.040) and 12 months (87.8% vs 91.5%, P = 0.010) postoperatively, and the renal function of the operated kidney (80.3% vs 88.2%, P < 0.001) were greater after robot-assisted partial nephrectomy. In robot-assisted partial nephrectomy, the volume of resected parenchyma was significantly smaller (27.2 vs 15.5 mL, P < 0.001), resulting in greater postoperative normal parenchymal volumes (120 vs 132 mL, P < 0.001) and a greater parenchymal preservation ratio (81.1% vs 90.1%, P < 0.001). The parenchymal preservation ratio was the strongest predictor of renal function preservation after surgery (P < 0.001, odds ratio 6.02). CONCLUSIONS Robot-assisted partial nephrectomy allows better preservation of split renal function than laparoscopic partial nephrectomy by increasing the parenchymal preservation ratio. This translates into better postoperative global renal function.

Abstract
Penile squamous cell carcinoma (PSCC) is a rare cancer, with approximately 2000 new cases in the United States and 35,000 globally every year. Multiple risk factors are involved in PSCC, but most importantly, the high-risk human papillomavirus infection is thought to be present in approximately 50% of cases. Penile squamous cell carcinoma presents as localized or locally advanced disease. Multiple prognostic markers have been explored over the past 3 decades, but lymph node status remains the strongest predictor of clinical outcomes. Surgical decisions are based on the primary tumor pathologic findings, nodal clinical examination, and imaging results. Most patients with high-risk advanced PSCC benefit from a multimodal treatment approach combining chemotherapy with consolidation surgical treatment. The role of neoadjuvant chemotherapy with radiation therapy has not been well explored in PSCC. Prospective clinical studies, like the International Penile Advanced Cancer Trial, have been launched to provide high-level evidence for multimodal treatment. The International Penile Advanced Cancer Trial is the first randomized clinical trial among patients with PSCC and is currently accruing, with the expectation to generate results in 2023. Unfortunately, most patients with high-risk locally advanced PSCC will have relapsed or refractory cancer after cisplatin-based combination chemotherapy. These patients have dismal outcomes with salvage chemotherapy, highlighting the major unmet need to expand our knowledge of the disease's biology and develop clinical trials that use novel systemic agents. This narrative review synthesizes relevant publications retrieved from PubMed. Our aim is to discuss current approaches in the management of PSCC, summarize ongoing efforts to improve care, and identify future areas for enhancing our understanding of the disease.

Abstract
BACKGROUND Vesical Imaging Reporting and Data System (VI-RADS) is a useful tool for evaluating muscle layer invasion of bladder cancer (BCa) on magnetic resonance imaging (MRI). PURPOSE To evaluate the diagnostic performance of bladder MRI to detect the muscle layer invasion of BCa using VI-RADS score and quantitative MRI parameters. METHODS Preoperative bladder MRI was performed in 73 BCa patients. Two observers independently evaluated the MR blinded to histopathological data and classified the tumors according to VI-RADS criteria. Moreover, the quantitative parameters (maximum tumor diameter; Dmax, tumor contact length; TCL, and tumor apparent diffusion coefficient; ADC values) were independently measured by observers. The diagnostic performance of the VI-RADS score and quantitative values were evaluated by using receiver operating characteristic (ROC) analysis. Interobserver agreement was evaluated using the weighted-kappa coefficient (κ). RESULTS For the VI-RADS score, the AUC (area under the curve) was 0.968 and accuracy was 90.4% for Observer 1, and AUC was 0.953, accuracy was 89% for Observer 2. The AUC of TCL, TCL/DMax, and ADC values was 0.918, 0.675, and 0.832. In patients with a VI-RADS score ≥ 3, when a threshold value of TCL > 19.5 mm is used as complementary to the VI-RADS score, the accuracy of MRI for Observer-1 increases 100% and 97.26% for Observer-2. There was a good-excellent agreement between the observers in assessing the VI-RADS scores and quantitative parameters. CONCLUSION Evaluation of bladder MRI using both VI-RADS criteria and TCL is successful and highly reproducible for detecting muscle layer invasion in patients with BCa.

Abstract
OBJECTIVE. The purpose of this study was to determine if contrast enhancement is necessary for MRI surveillance of clinical T1a (cT1a) solid renal masses. MATERIALS AND METHODS. With institutional review board approval, 36 patients who underwent two or more contrast-enhanced (CE) MRI examinations (median, four examinations; range, two to 10 examinations) for surveillance of 39 cT1a solid renal masses between 2009 and 2019 (median time between scans, 2 years; range, 1-7 years) were evaluated. Two radiologists independently measured renal mass size and assessed tumor stage in two sessions for baseline and follow-up examinations using T1-weighted nephrographic phase CE-MRI and unenhanced single-shot T2-weighted MRI in mixed order with a 4-week washout period. Comparisons were performed using the Wilcoxon sign-rank test and Pearson correlation. Bland-Altman and intraclass correlation determined interobserver agreement. RESULTS. Mean size ± SD of renal masses on CE-MRI and T2-weighted MRI were 18 ± 5 mm (range, 9-37 mm) and 18 ± 5 mm (range, 9-37 mm) for radiologist 1 and 19 ± 7 mm (range, 10-39 mm) and 19 ± 6 mm (range, 10-39 mm) for radiologist 2 with near perfect correlation (for radiologist 1, β = 0.9897; for radiologist 2, β = 0.9317; p < .001). Interob-server agreement for measurements comparing radiologist 1 and radiologist 2 on CEMRI and T2-weighted MRI and intraobserver agreement for measurements on CE-MRI and T2-weighted MRI were excellent. Mean growth rate of renal masses measured on CE-MRI and T2-weighted MRI were 2 ± 2 mm (range, -5 to 8 mm) and 2 ± 3 mm (range, -3 to 8 mm) for radiologist 1 and 3 ± 5 mm (range, -1 to 18 mm) and 3 ± 6 mm (range, -1 to 24 mm) for radiologist 2 with high correlation (for radiologist 1, β = 0.8313 [p < .001]; for radiologist 2, β = 0.848 [p = .002]). At baseline, all tumors were subjectively cT1a on CE-MRI and T2-weighted MRI (p > .99, intraclass correlation coefficient [ICC] = 1). During follow-up, one mass progressed to T3 on CE-MRI and T2-weighted MRI for radiologist 1 and radiologist 2 (p > .99, ICC = 1). CONCLUSION. In this study, size measurements on unenhanced T2-weighted MRI had near perfect correlation to measurements using CE-MRI in cT1a solid renal masses undergoing surveillance, with high agreement between and within observers. Clinical staging did not differ comparing T2-weighted MRI and CE-MRI, with near perfect agreement. Contrast enhancement is not necessary for follow-up size measurements in cT1a solid renal masses with MRI.

Abstract
BACKGROUND We sought to analyze the usefulness of pretreatment C-reactive protein (CRP) as a predictor of survival and oncological outcomes in patients with renal cell carcinoma (RCC). METHODS Retrospective international analysis of patients with RCC with pretreatment CRP values from 2006 to 2017. A CRP of more than >5 mg/L was deemed elevated. The cohort was subdivided into 2 groups for analysis (normal CRP ≤5 mg/L; elevated CRP >5). Primary outcome was overall survival (OS) and secondary outcome was recurrence-free survival (RFS). Kaplan-Meier analyses (KMA) and multivariable analyses (MVA) were used to delineate survival outcomes and their predictors. RESULTS We analyzed 2445 patients (1641 male/804 female; normal CRP 1056/elevated CRP 1389; mean follow-up 36 months). Patients with elevated CRP had a higher incidence of hypertension (P = .001), higher body mass index (P < .001), and larger tumor size (6.0 cm vs 3.9 cm; P < .001). MVA for RFS demonstrated elevated CRP (hazard ratio [HR], 1.85; P = .005), tumor size (HR, 1.1; P < .001), and high tumor grade (HR, 3.1; P < .001) to be independent risk factors. For normal vs elevated CRP, KMA for RFS of stages 1-4 RCC revealed a 5-year RFS of 93% vs 88% (P = .001), 95% vs 83% (P = .163), 84% vs 62% (P = .001), and 58% vs 60% (P = .513), respectively. KMA MA KMA for OS of stages 1-4 RCC revealed a 5-year OS of 98% vs 81% (P = .001), 94% vs 80% (P = .103), 94% vs 65% (P = .001), and 99% vs 38% (P < .001), respectively. CONCLUSIONS Pretreatment CRP was an independent predictor of RFS and OS in an international multicenter cohort of patients with RCC.

Abstract
Penile squamous cell carcinoma (PSCC) is a rare cancer with orphan disease designation and a prevalence of 0.1-1 per 100,000 men in high-income countries, but it constitutes up to 10% of malignancies in men in some African, Asian and South American regions. Risk factors for PSCC include the absence of childhood circumcision, phimosis, chronic inflammation, poor penile hygiene, smoking, immunosuppression and infection with human papillomavirus (HPV). Several different subtypes of HPV-related and non-HPV-related penile cancers have been described, which also have different prognostic profiles. Localized disease can be effectively managed by topical therapy, surgery or radiotherapy. As PSCC is characterized by early lymphatic spread and imaging is inadequate for the detection of micrometastatic disease, correct and upfront surgical staging of the inguinal lymph nodes is crucial in disease management. Advanced stages of disease require multimodal management. Optimal sequencing of treatments and patient selection are still being investigated. Cisplatin-based chemotherapy regimens are the mainstay of systemic therapy for advanced PSCC, but they have poor and non-durable responses and high rates of toxic effects, indicating a need for the development of more effective and less toxic therapeutic options. Localized and advanced penile cancers and their treatment have profound physical and psychosexual effects on the quality of life of patients and survivors by altering sexual and urinary function and causing lymphoedema.

[PMID: 33598428 PMCID: PMC7882704 DOI: 10.3389/fonc.2020.600380] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2020] [Accepted: 12/08/2020] [Indexed: 11/22/2022] Open
Abstract
Purpose The most common disadvantage of 11C-choline positron emission tomography and computed tomography (PET/CT) in diagnosing early-stage prostate cancer (PCa) is its poor sensitivity. In spite of many efforts, this imaging modality lacks the ideal parameter of choline metabolism for the diagnosis of PCa, and the single metabolic parameter, that is, maximal standardized uptake value (SUVmax), based on this imaging modality is insufficient. 11C-choline PET/CT-based multi-metabolic parameter combination can help break this limitation. Materials and Methods Before surgery, SUVmax of choline, which is the most common metabolic parameter of 11C-choline PET/CT, mean standardized uptake value (SUVmean), prostate-to-muscle (P/M) ratio, metabolic tumor volume (MTV) and total lesion glycolysis (TLG) from 74 patients with histologically proven PCa were quantified. A total of 13 patients with focal chronic prostatitis without severe features and 30 patients with benign prostate hyperplasia were used for comparison. Univariable and multivariable analyses were performed to compare the patient characteristics and metabolic parameters of 11C-choline PET/CT. The performance of single parameters and the combination of parameters were assessed by using logistic regression models. Results The comparable c-statistics, which mean the area under the ROC curve in the logistic regression model, of SUVmax, SUVmean, and P/M ratio are 0.657, 0.667, and 0.672, respectively. The c-statistic significantly rose to 0.793 when SUVmax and SUVmean were combined with the P/M ratio. This parameter combination performed the best for PCa cases with all biochemical recurrence risks and for PCa patients grouped by different risk. The greatest improvement over a single parameter, such as P/M ratio, was noted in the group of low-risk PCa, with values of 0.535 to 0.772 for the three-parameter combination. And in the histopathological level, the Ki-67 index is positively correlated with the P/M ratio (r=0.491, p=0.002). Conclusion P/M ratio is a more ideal parameter than SUVmax as a single parameter in early-stage PCa diagnosis. According to our data, the combination of SUVmax, SUVmean, and P/M ratio as a composite parameter for diagnosis of early stage PCa improves the diagnostic accuracy of 11C-choline PET/CT.

Serum CXCL5 level is associated with tumor progression in penile cancer. Biosci Rep 2021; 41:227614. [PMID: 33458757 PMCID: PMC7843497 DOI: 10.1042/bsr20202133] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 01/09/2021] [Accepted: 01/14/2021] [Indexed: 12/01/2022] Open
Abstract
Chemokine (C-X-C motif) ligand 5 is an important regulator of tumor progression in many cancers, and could serve as potential serum cancer biomarker. Our initial analysis identified CXCL5 as a cancer-related gene highly expressed in PC. Patients with PC exhibited markedly higher preoperative serum CXCL5 levels compared with that in healthy individuals (P<0.001). The area under the curve (AUC) was 0.880 with the sensitivity of 84.0%, and specificity of 80.4% to distinguish PC. Serum CXCL5 levels were also significantly decreased following tumor resection in patients with PC (P=0.001). Preoperative serum CXCL5 level was significantly associated with clinicopathological characteristics including T stage (P=0.001), nodal status (P<0.001), and pelvic lymph node metastasis (P=0.018). Cox regression analysis showed that serum CXCL5 level could serve as an independent prognostic factor for disease-free survival with a HR of 6.363 (95% CI: 2.185–18.531, P=0.001). CXCL5 and its receptor CXCR2 exhibited correlated expression pattern in PC tissues. Differential CXCL5 expression was observed in normal penile tissues, PC cell lines, and their culture supernatants. Furthermore, knockdown of CXCL5 or CXCR2 expression markedly suppressed malignant phenotypes (cell proliferation, clonogenesis, apoptosis escape, migration, and invasion), attenuated STAT3 and AKT signaling, and reduced MMP2/9 secretion in PC cell lines. In conclusion, our findings revealed that serum CXCL5 level might serve as a potential diagnostic and prognostic cancer biomarker for penile cancer. Autocrine CXCL5/CXCR2 signaling might activate multiple downstream oncogenic signaling pathways (STAT3, AKT, MMP2/9) to promote malignant progression of PC, which may warrant further investigation in the future.

Abstract
Urothelial carcinoma of the bladder is a common urologic malignancy. Complex factors, such as local stage, tumor grade, biologic potential, and various conditions, can affect the treatment strategy for bladder cancer. However, the local stage-in particular, the presence or absence of muscle invasion-significantly influences decisions regarding treatment strategy. The role of cystoscopy for screening, diagnosis, and transurethral resection cannot be overlooked. The importance of local staging with magnetic resonance imaging is increasing; magnetic resonance imaging of the bladder is considered a useful staging modality. Moreover, a radiologic reporting system for evaluating and scoring muscle invasion of bladder cancer was recently released. This system is based on multiparametric magnetic resonance imaging and is also expected to be feasible for post-treatment follow-up of bladder cancer. In this review, we discuss the role of magnetic resonance imaging in the local staging of urothelial carcinoma of the urinary bladder and post-treatment imaging. In addition, several technical aspects for obtaining appropriate quality magnetic resonance images of the bladder will be discussed.

Abstract
BACKGROUND Long-term survival outcomes of patients who undergo endoscopic management of non-invasive upper tract urothelial carcinoma remain uncertain. The longest mean follow-up period in previous studies was 6.1 years. This study reports the long-term outcomes of patients with upper tract urothelial carcinoma who underwent ureteroscopic ablation at a single institution over a 28-year period. METHODS We identified all patients who underwent ureteroscopic management of upper tract urothelial carcinoma as their primary treatment at our institution between January 1991 and April 2011. Survival outcomes, including overall survival, cancer-specific survival, upper-tract recurrence-free survival and renal unit survival, were estimated using Kaplan-Meier methodology. RESULTS A total of 15 patients underwent endoscopic management, with a mean age at diagnosis of 66 years. All patients underwent ureteroscopy, and biopsy-confirmed pathology was obtained. Median (range; mean) follow-up was 11.7 (2.3-20.9, 11.9) years. Upper tract recurrence occurred in 87% (n = 13) of patients. Twenty percent (n = 3) of patients proceeded to nephroureterectomy. The estimated cancer-specific survival rate was 93% at 5, 10, 15 and 20 years. Estimated overall survival rates were 86, 80, 54 and 20% at 5, 10, 15 and 20 years. Only one patient experienced cancer-specific mortality. The estimated mean and median overall survival times were 14.5 and 16.6 years, respectively. The estimated mean cancer-specific survival time was not reached. CONCLUSIONS Although upper tract recurrence is common, endoscopic management of non-invasive upper tract urothelial carcinoma provides a 90% cancer-specific survival rate at 20 years in selected patients.

Abstract
OBJECTIVES To prospectively compare the diagnostic efficacy of conventional diffusion-weighted imaging (DWI) and diffusion kurtosis imaging (DKI) in differentiating between muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC). METHODS Multiple b value DWIs were performed using a 3-T magnetic resonance (MR) imaging unit in fifty-one patients with bladder cancer including MIBC and NMIBC confirmed by histopathological findings. DWI data were postprocessed using mono-exponential and DKI models to calculate the apparent diffusion coefficient (ADC), apparent diffusional kurtosis (Kapp), and kurtosis-corrected diffusion coefficient (Dapp). Receiver-operating characteristic (ROC) analysis was performed to compare the diagnostic efficacy of all diffusion parameters. RESULTS All parameters differed significantly between MIBC and NIMBC including increased Kapp, decreased Dapp and ADC (all p < 0.001). Only the combination of Dapp and Kapp was significantly higher than ADC (p < 0.05), whilst Dapp and Kapp were not statistically different from ADC. CONCLUSIONS Both conventional DWI and DKI models are beneficial in differentiating between MIBC and NMIBC, whilst the combination of Dapp and Kapp can produce a more robust value than conventional ADC value in evaluating aggressiveness of bladder cancer.

Abstract
Background Patients with prostate cancer (PCa) commonly suffer from bone metastasis during disease progression. This study aims to construct and validate a nomogram to quantify bone metastasis risk in patients with PCa. Methods Clinicopathological data of patients diagnosed with PCa between 2010 and 2015 were retrospectively retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Predictors for bone metastasis were identified by logistic regression analyses to establish a nomogram. The concordance index (c-index) and calibration plots were generated to assess the nomogram’s discrimination, and the area under the receiver operating characteristic curve (AUC) was used to compare the precision of the nomogram with routine staging systems. The nomogram’s clinical performance was evaluated by decision curve analysis (DCA) and clinical impact curves (CIC). Independent prognostic factors were identified by Cox regression analysis. Results A total of 168,414 eligible cases were randomly assigned to the training cohort or validation cohort at a ratio of 1:1. The nomogram, which was established based on independent factors, showed good accuracy, with c-indexes of 0.911 in the training set and 0.910 in the validation set. Calibration plots also approached 45 degrees. After other distant metastatic sites were included in the predictive model, the new nomogram displayed superior prediction performance. The AUCs and net benefit of the nomograms were both higher than those of other routine staging systems. Furthermore, bone metastasis prediction points were shown to be a new risk factor for overall survival. Conclusions Novel validated nomograms can effectively predict the risk of bone metastasis in patients with PCa and help clinicians improve cancer management.

Abstract
OBJECTIVES To determine whether there is an association between blood eosinophil count and percentage with the recurrence of nonmuscle invasive bladder cancer (NMIBC) during Bacillus Calmette-Guérin (BCG) maintenance therapy with our preliminary results. METHODS A total of 53 patients with NMIBC underwent BCG immunotherapy between January 2015 and September 2018, and met our inclusion criteria were included in the study. The parameters age, gender, smoking status, comorbidity, blood neutrophil, lymphocyte and eosinophil counts, blood eosinophil percentage, previous single postoperative intravesical chemotherapy instillation, tumor characteristic, and total and maintenance dose numbers of BCG were extracted from our medical records and compared between patients with response and with recurrence. RESULTS Blood eosinophil count and percentage were significantly higher in patients with recurrence compared to patients with response (0.263 ± 0.37 vs. 0.0134 ± 0.021, p = 0.01 and 0.31 ± 0.29 vs. 0.17 ± 0.27, p = 0.01). Other parameters were similar in patients with recurrence and response. Receiver-operating characteristic analysis showed a considerable diagnostic value of blood eosinophil count and percentage in the prediction of bladder cancer recurrence during BCG immunotherapy. CONCLUSION Blood eosinophil count and percentage in patients with NMIBC can predict the disease recurrence during the BCG immunotherapy. Our research raised new questions and assumptions about the role of eosinophils during BCG immunotherapy.

Abstract
Background Growing evidence supports the pivotal role of long non-coding RNAs (lncRNAs) in the regulation of cancer development and progression. Their expression patterns and biological function in muscle invasive bladder cancer (MIBC) remain elusive. Methods Transcript levels of lncRNA miR-31 host gene (MIR31HG) and its splice variants were measured in our MIBC cohort (n = 102) by qRT-PCR, and validated in silico by the TCGA cohort (n = 370). Kaplan-Meier and multiple Cox regression analysis were conducted to evaluate the survival significance of MIR31HG and its splice variants. Functional experiments were performed to examine the proliferation and migration abilities of MIR31HG and its splice variants by knockdown approaches. Results In this study, a decreased expression of MIR31HG was found in bladder cancer cells and tissues, except in the basal subtype. Survival analysis showed that high expression of MIR31HG was associated with poor overall survival (OS) and disease-free survival (DFS) in patients with MIBC of basal subtype. Two splice variants of MIR31HG lacking exon 1 (MIR31HGΔE1) and exon 3 (MIR31HGΔE3) were identified to have specific expression patterns in different molecular subtypes of our MIBC cohort. MIR31HGΔE3 was highly expressed in basal subtype tumors. A high expression of MIR31HGΔE1 and MIR31HGΔE3 was associated with worse OS and DFS in our cohort. In vitro experiments revealed that knockdown of MIR31HG inhibits cell proliferation, colony formation, and migration in bladder cancer. Cell proliferation and migration assays after knockdown of splice variants of MIR31HG showed corresponding roles for the full-length transcript. Conclusions Our study demonstrates that MIR31HG and its splice variants could serve as biomarkers for the classification and prognosis prediction of patients with MIBC.

Abstract
The clinical parameters and the histological and immunohistochemical findings of a prospective protocolized series of 27 prostate carcinoma patients with oligometastatic disease followed homogeneously were analyzed. Lymph nodes (81.5%) and bones (18.5%) were the only metastatic sites. Local control after metastatic directed treatment was achieved in 22 (81.5%) patients. A total of 8 (29.6%) patients developed castration-resistant prostate cancer. Seventeen (63%) patients presented with non-organ confined disease. The Gleason index 8-10 was the most frequently observed (12 cases, 44.4%) combined grade. Positive immunostainings were detected with androgen receptor (100%), PGP 9.5 (74%), ERG (40.7%), chromogranin A (29.6%), and synaptophysin (18.5%) antibodies. The Ki-67 index value > 5% was observed in 15% of the cases. L1CAM immunostaining was negative in all cases. Fisher exact test showed that successful local control of metastases was associated to mild inflammation, organ confined disease, Ki-67 index < 5%, and Gleason index 3 + 3. A castration resistant status was associated with severe inflammation, atrophy, a Gleason index higher than 3 + 3, Ki-67 index ≥ 5%, and positive PGP 9.5, chromogranin A, and synaptophysin immunostainings. In conclusion, oligometastatic prostate adenocarcinoma does not have a specific clinical-pathologic profile. However, some histologic and immunohistochemical parameters of routine use may help with making therapeutic decisions.

Abstract
PURPOSE Penile cancer is highly prevalent in low- and middle-income countries, with significant morbidity and mortality rates. The first Brazilian consensus provides support to improve penile cancer patients' outcomes, based on expert's opinion and evidence from medical literature. METHODS Fifty-one Brazilian experts (clinical oncologists, radiation oncologists, urologists, and pathologists) assembled and voted 104 multiple-choice questions, confronted the results with the literature, and ranked the levels of evidence. RESULTS Healthcare professionals need to deliver more effective communication about the risk factors for penile cancer. Staging and follow-up of patients include physical examination, computed tomography, and magnetic resonance imaging. Close monitoring is crucial, because most recurrences occur in the first 2-5 years. Lymph-node involvement is the most important predictive factor for survival, and management depends on the location (inguinal or pelvic) and the number of lymph nodes involved. Conservative treatment may be helpful in selected patients without compromising oncological outcomes; however, surgery yields the lowest rate of local recurrence. CONCLUSION This consensus provides an essential decision-making orientation regarding this challenging disease.

Abstract
Radical cystectomy (RC) represents a standard treatment for non-metastatic muscle-invasive and select high-risk non-muscle invasive bladder cancer. Lymphadenectomy performed at time of RC identifies nodal metastases in up to 25% of patients despite normal imaging. There has been an increasing utilization of pelvic lymph node dissection (PLND) with RC since 1950, and in fact lymph node dissection is now recommended in contemporary National Comprehensive Cancer Network (NCCN) guidelines. Benefits of removing of nodal disease include improved staging, guidance for adjuvant treatment, and potentially improved oncologic outcomes. Advantages of dissection have been suggested among both node-negative and node-positive patients. Numerous studies have attempted to define the optimal dissection characteristics of lymphadenectomy with regard to nodal yield and anatomic boundaries of dissection. The ideal extent of lymphadenectomy remains uncertain due to the retrospective and non-randomized nature of the majority of existing reports, which are thereby limited by significant confounding and selection bias. Two randomized controlled trials have investigated this issue, one of which LEA AUO AB 25/02 recently reported its outcomes, demonstrating no significant improvement in 5-year outcomes with an extended dissection. Meanwhile, the Southwest Oncology Group 1011 trial has completed enrollment and data are maturing. While current data preclude definitive recommendations, herein we review the why, when, and how to perform a PLND for bladder cancer.

Outcomes of Robot-assisted Partial Nephrectomy for Clinical T3a Renal Masses: A Multicenter Analysis. Eur Urol Focus 2020; 7:1107-1114.

Abstract
BACKGROUND Use of partial nephrectomy (PN) in T3 renal cell carcinoma (RCC) is controversial. OBJECTIVE To evaluate quality outcomes of robot-assisted PN (RAPN) for clinical T3a renal masses (cT3aRM). DESIGN, SETTING, AND PARTICIPANTS This was a retrospective multicenter analysis of patients with cT3aN0M0 RCC who underwent RAPN. INTERVENTION RAPN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was a trifecta composite outcome of negative surgical margins, warm ischemia time (WIT) ≤25 min, and no perioperative complications. The optimal outcome was defined as achieving this trifecta and ≥90% preservation of the estimated glomerular filtration rate (eGFR) and no stage upgrading of chronic kidney disease. Multivariable analysis (MVA) identified risk factors associated with lack of the optimal outcome. Kaplan-Meier analysis was conducted for survival outcomes. RESULTS AND LIMITATIONS Analysis was conducted for 157 patients (median follow-up 26 mo). The median tumor size was 7.0 cm (interquartile range [IQR] 5.0-7.8) and the median RENAL score was 9 (IQR 8-10). Median estimated blood loss (EBL) was 242 ml (IQR 121-354) and the median WIT was 19 min (IQR 15-25). A total of 150 patients (95.5%) had negative margins. Complications were noted in 25 patients (15.9%), with 4.5% having Clavien grade 3-5 complications. The median change in eGFR was 7 ml/min/1.72 m2, with ≥90% eGFR preservation in 55.4%. The trifecta outcome was achieved for 64.3% and the optimal outcome for 37.6% of the patients. MVA revealed that greater age (odds ratio [OR] 1.06; p = 0.002), increasing RENAL score (OR 1.30; p = 0.035), and EBL >300 ml (OR 5.96, p = 0.006) were predictive of failure to achieve optimal outcome. The 5-yr recurrence-free survival, cancer-specific survival, and overall survival, were 82.1%, 93.3%, and 91.3%, respectively. Limitations include the retrospective design. CONCLUSIONS RAPN for select cT3a renal masses is feasible and safe, with acceptable quality outcomes. Further investigation is requisite to delineate the role of RAPN in cT3a RCC. PATIENT SUMMARY Robot-assisted partial nephrectomy in patients with stage 3a kidney cancer provided acceptable survival, functional, and morbidity outcomes in the hands of experienced surgeons, and may be considered as an option when clinically indicated.
