ABSTRACT

OBJECTIVE: To assess recurrence-free survival (RFS) in patients with undetectable tumour-informed circulating tumour DNA (ctDNA) before radical cystectomy (RC) and evaluate if those who converted from detectable to undetectable ctDNA status after RC have similar RFS outcomes as those with persistently undetectable ctDNA status. PATIENTS AND METHODS: Patients who underwent RC had prospectively and longitudinally collected tumour-informed ctDNA analyses during 2021-2023. ctDNA status was informed from the pre-RC specimen. The minimal residual disease (MRD) window was defined as the initial 90 days after RC. RFS was evaluated using the Kaplan-Meier method. Cox regression analysis was performed to find predictors of disease recurrence. RESULTS: The cohort included 135 patients with 647 ctDNA analyses. The median (interquartile range [IQR]) age was 71 (63-77) years. Over a median (IQR) follow-up of 11 (7-18) months, 41 patients (30%) had a recurrence. Pre-RC undetectable ctDNA status was found in 54 patients (40%). The RFS rates at 6, 12, and 21 months were 98%, 93%, and 82%, respectively. Of 77 patients with undetectable ctDNA status at the MRD window available for conversion dynamics analysis, 43 had persistently undetectable ctDNA status (both at pre-RC and MRD window) and 31 converted from pre-RC detectable to MRD undetectable status (conversion group). The persistently undetectable group had significantly better RFS than the conversion group (log-rank, P < 0.001), with 12-month RFS rates of 97% vs 51%, and 18-month RFS rates of 88% vs 51%, respectively. On Cox multivariate analysis, only the conversion group status predicted disease recurrence. CONCLUSIONS: Patients with undetectable pre-RC ctDNA status have a favourable prognosis and may be candidates for treatment de-escalation. Those with persistently undetectable ctDNA had superior RFS compared to the conversion group. Pre-RC ctDNA status should be incorporated into trials examining ctDNA use in clinical decision-making.

ABSTRACT

OBJECTIVE: To analyse surgical, functional, and mid-term oncological outcomes of robot-assisted nephroureterectomy (RANU) in a contemporary large multi-institutional setting. PATIENTS AND METHODS: Data were retrieved from the ROBotic surgery for Upper tract Urothelial cancer STtudy (ROBUUST) 2.0 database, an international, multicentre registry encompassing data of patients with upper urinary tract urothelial carcinoma undergoing curative surgery between 2015 and 2022. The analysis included all consecutive patients undergoing RANU except those with missing data in predictors. Detailed surgical, pathological, and postoperative functional data were recorded and analysed. Oncological time-to-event outcomes were: recurrence-free survival (RFS), metastasis-free survival (MFS), cancer-specific survival (CSS), and overall survival (OS). Survival analysis was performed using the Kaplan-Meier method, with a 3-year cut-off. A multivariable Cox proportional hazard model was built to evaluate predictors of each oncological outcome. RESULTS: A total of 1118 patients underwent RANU during the study period. The postoperative complications rate was 14.1%; the positive surgical margin rate was 4.7%. A postoperative median (interquartile range) estimated glomerular filtration rate decrease of -13.1 (-27.5 to 0) mL/min/1.73 m2 from baseline was observed. The 3-year RFS was 59% and the 3-year MFS was 76%, with a 3-year OS and CSS of 76% and 88%, respectively. Significant predictors of worse oncological outcomes were bladder-cuff excision, high-grade tumour, pathological T stage ≥3, and nodal involvement. CONCLUSIONS: The present study contributes to the growing body of evidence supporting the increasing adoption of RANU. The procedure consistently offers low surgical morbidity and can provide favourable mid-term oncological outcomes, mirroring those of open NU, even in non-organ-confined disease.

ABSTRACT

INTRODUCTION: The combination of sequential intravesical gemcitabine and docetaxel (Gem/Doce) chemotherapy has been considered a feasible option for BCG (Bacillus Calmette-Guérin) treatment in non-muscle invasive bladder cancer (NMIBC), gaining popularity during BCG shortage period. We seek to determine the efficacy of the treatment by comparing Gem/Doce induction alone vs induction with maintenance, and to evaluate the treatment outcomes of two different dosage protocols. METHODS: A bi-center retrospective analysis of consecutive patients treated with Gem/Doce for NMIBC between 2018 and 2023 was performed. Baseline characteristics, risk group stratification (AUA 2020 guidelines), pathological, and surveillance reports were collected. Kaplan-Meier survival analysis was performed to detect Recurrence-free survival (RFS). RESULTS: Overall, 83 patients (68 males, 15 females) with a median age of 73 (IQR 66-79), and a median follow-up time of 18 months (IQR 9-25), were included. Forty-one had an intermediate-risk disease (49%) and 42 had a high-risk disease (51%). Thirty-seven patients (45%) had a recurrence; 19 (23%) had a high-grade recurrence. RFS of Gem/Doce induction-only vs induction + maintenance was at 6 months 88% vs 100%, at 12 months 71% vs 97%, at 18 months 57% vs 91%, and at 24 months 31% vs 87%, respectively (log-rank, p < 0.0001). Patients who received 2 g Gemcitabine with Docetaxel had better RFS for all-grade recurrences (log-rank, p = 0.017). However, no difference was found for high-grade recurrences. CONCLUSION: Gem/Doce induction with maintenance resulted in significantly better RFS than induction-only. Combining 2 g gemcitabine with docetaxel resulted in better RFS for all-grade but not for high-grade recurrences. Further prospective trials are necessary to validate our results.

ABSTRACT

BACKGROUND: Robotic-assisted radical cystectomy (RARC) offers decreased blood loss during surgery, shorter hospital length of stay, and lower risk for thromboembolic events without hindering oncological outcomes. Cutaneous ureterostomies (UCS) are a seldom utilized diversion that can be a suitable alternative for a selected group of patients with competing co-morbidities and limited life expectancy. OBJECTIVE: To describe operative and perioperative characteristics as well as oncological outcomes for patients that underwent RARC + UCS. METHODS: Patients that underwent RARC + UCS during 2013-2023 in 3 centers (EU = 2, US = 1) were identified in a prospectively maintained database. Baseline characteristics, pathological, and oncological outcomes were analyzed. Descriptive statistics and survival analysis were performed using R language version 4.3.1. RESULTS: Sixty-nine patients were included. The median age was 77 years (IQR 70-80) and the median follow-up time was 11 months (IQR 4-20). Ten patients were ASA 4 (14.5%). Nine patients underwent palliative cystectomy (13%). The median operation time was 241 min (IQR 202-290), and the median hospital stay was 8 days (IQR 6-11). The 30-day complication rate was 55.1% (grade ≥ 3a was 14.4%), and the 30-day readmission rate was 17.4%. Eleven patients developed metastatic recurrence (15.9%), and 14 patients (20.2%) died during the follow-up period. Overall survival at 6, 12, and 24 months was 84%, 81%, and 73%, respectively. CONCLUSIONS: RARC + UCS may offer lower complication and readmission rates without the need to perform enteric anastomosis, it can be considered in a selected group of patients with competing co-morbidities, or limited life expectancy. Larger prospective studies are necessary to validate these results.

ABSTRACT

PURPOSE: To assess the impact of neoadjuvant and adjuvant chemotherapy on survival outcomes, within a large multicenter cohort of Upper tract urothelial carcinoma patients treated with Nephroureterectomy. METHODS: A multicenter retrospective analysis utilizing the Robotic surgery for Upper Tract Urothelial Cancer Study registry was performed. Baseline, preoperative, perioperative, and pathologic variables of three groups of patients receiving surgery only, neoadjuvant or adjuvant chemotherapy were compared. Categorical and continuous variables among the three subgroups were compared with Chi square and ANOVA tests. The impact of perioperative chemotherapy on survival outcomes was assessed with the Kaplan Meier method. Univariable and multivariable Cox regression analyses were performed to identify predictors of survival. RESULTS: Overall, 1,994 patients were included. Overall and Clavien grade ≥3 complications rates were comparable among the three subgroups (p = 0.65 and p = 0.92). At Kaplan Meier analysis, neoadjuvant chemotherapy significantly improved cancer-specific survival (p = 0.03) and overall survival (p = 0.03) probabilities of patients with cT ≥ 3 tumors and of those with positive cN (p = 0.03 and p = 0.02). On multivariable analysis, neoadjuvant chemotherapy was independently associated with an improvement of cancer-specific survival in cT ≥ 3 patients (HR 0.44; p = 0.04), and of both cancer-specific survival (HR 0.50; p = 0.03) and overall survival (HR 0.53; p = 0.02) probabilities in positive cN patients. CONCLUSIONS: This large multicenter retrospective analysis suggests significant survival benefit in Upper tract urothelial carcinoma patients with either locally advanced or clinically positive nodes disease receiving neoadjuvant chemotherapy. These findings can be regarded as "hypothesis generating", stimulating future trials focusing on such advanced stages.

ABSTRACT

PURPOSE OF REVIEW: Tumor-informed circulating tumor DNA (ctDNA) is an emerging biomarker in urothelial carcinoma. Recent clinical trials have investigated the integration of ctDNA into clinical decision-making in patients with muscle-invasive bladder cancer, their findings suggest that ctDNA may potentially revolutionize the way we stratify patients to different treatment modalities. RECENT FINDINGS: ctDNA informed from TURBT specimens was found to be prognostic of disease outcomes among patients with localized nonmetastatic bladder cancer. Detectable precystectomy ctDNA status was associated with worse survival outcomes. Additionally, ctDNA status was predictive of adverse disease on radical cystectomy, including the likelihood of disease upstaging, lymph node involvement, and having a locally advanced disease (≥pT3a). In the postcystectomy minimal residual disease (MRD) period, ctDNA status may refine patient selection to adjuvant therapy, and if validated by ongoing clinical trials, patients with undetectable postcystectomy ctDNA status may forgo adjuvant treatment, regardless of pathological stage. On the contrary, patients with pre or postcystectomy detectable ctDNA status may benefit from treatment intensification. SUMMARY: The integration of ctDNA in clinical decision-making has the potential to revolutionize the way we manage urothelial carcinoma by refining patient selection to different treatment modalities. This approach could ultimately lead to personalization of oncological care, with the potential to reduce both treatment-related and financial toxicity.

ABSTRACT

OBJECTIVES: To compare the safety and efficacy of oral apixaban with that of injectable enoxaparin after robot-assisted radical cystectomy (RARC) for venous thromboembolism (VTE) thromboprophylaxis. MATERIALS AND METHODS: We conducted a retrospective review of prospectively collected data for all RARC patients treated at our tertiary care centre between 2018 and 2022. The study included two groups: patients who were subject to a prospectively implemented protocol from October 2021 to the present, comprising a 21-day postoperative course of apixaban 2.5 mg twice daily after discharge, and patients treated prior to October 2021 who received enoxaparin 40 mg daily. Baseline demographics and clinical characteristics, such as VTE (defined as deep vein thrombosis and pulmonary embolism), were analysed. The primary outcome was incidence of symptomatic VTE confirmed with definitive imaging within 90 days of RARC. Secondary outcomes included major bleeding, complications, readmission, and mortality within 30 days postoperatively. Descriptive statistics included baseline patient characteristics, operative information and complications. Differences in baseline characteristics and postoperative data were compared between groups. Multivariate logistic regression was used to determine associations between variables and the primary outcome. RESULTS: A total of 124 patients received apixaban and 250 patients received enoxaparin prophylaxis. Ten patients (2.7%) experienced a VTE within 90 days postoperatively (two [1.6%] apixaban group vs eight [3.2%] enoxaparin group; P = 0.5). After patient stratification into European Association of Urology risk groups, no statistically significant difference in VTE rates was seen between groups in the apixaban (2.7% high- + intermediate-risk group vs 1.1% low-risk group; P = 0.5) and enoxaparin cohorts (4.3% high- + intermediate-risk group vs 2.5% low-risk group; P = 0.5). On multivariate logistic regression, no variables were associated with the development of the primary outcome. CONCLUSION: Prophylaxis with apixaban and enoxaparin showed no statistically significant differences in VTE rates among RARC patients. Apixaban appears to be safe and effective for VTE prophylaxis after RARC.

ABSTRACT

Extracellular vesicles (EVs)-including apoptotic bodies, microvesicles, and exosomes-are released by almost all cell types and contain molecular footprints from their cell of origin, including lipids, proteins, metabolites, RNA, and DNA. They have been successfully isolated from blood, urine, semen, and other body fluids. In this review, we discuss the current understanding of the predictive value of EVs in prostate and renal cancer. We also describe the findings supporting the use of EVs from liquid biopsies in stratifying high-risk prostate/kidney cancer and advanced disease, such as castration-resistant (CRPC) and neuroendocrine prostate cancer (NEPC) as well as metastatic renal cell carcinoma (RCC). Assays based on EVs isolated from urine and blood have the potential to serve as highly sensitive diagnostic studies as well as predictive measures of tumor recurrence in patients with prostate and renal cancers. Overall, we discuss the biogenesis, isolation, liquid-biopsy, and therapeutic applications of EVs in CRPC, NEPC, and RCC.

ABSTRACT

PURPOSE: We sought to evaluate outcomes of lymph node dissection (LND) in patients with upper tract urothelial carcinoma. MATERIALS AND METHODS: We performed a multicenter retrospective analysis utilizing the ROBUUST (for RObotic surgery for Upper Tract Urothelial Cancer Study) registry for patients who did not undergo LND (pNx), LND with negative lymph nodes (pN0) and LND with positive nodes (pN+). Primary and secondary outcomes were overall survival (OS) and recurrence-free survival (RFS). Multivariable analyses evaluated predictors of outcomes and pathological node positivity. Kaplan-Meier analyses (KMAs) compared survival outcomes. RESULTS: A total of 877 patients were analyzed (LND performed in 358 [40.8%]/pN+ in 73 [8.3%]). Median nodes obtained were 10.2 for pN+ and 9.8 for pN0. Multivariable analyses noted increasing age (OR 1.1, p <0.001), pN+ (OR 3.1, p <0.001) and pathological stage pTis/3/4 (OR 3.4, p <0.001) as predictors for all-cause mortality. Clinical high-grade tumors (OR 11.74, p=0.015) and increasing tumor size (OR 1.14, p=0.001) were predictive for lymph node positivity. KMAs for pNx, pN0 and pN+ demonstrated 2-year OS of 80%, 86% and 42% (p <0.001) and 2-year RFS of 53%, 61% and 35% (p <0.001), respectively. KMAs comparing pNx, pN0 ≥10 nodes and pN0 <10 nodes showed no significant difference in 2-year OS (82% vs 85% vs 84%, p=0.6) but elicited significantly higher 2-year RFS in the pN0 ≥10 group (60% vs 74% vs 54%, p=0.043). CONCLUSIONS: LND during nephroureterectomy in patients with positive lymph nodes provides prognostic data, but is not associated with improved OS. LND yields ≥10 in patients with clinical node negative disease were associated with improved RFS. In high-grade and large tumors, lymphadenectomy should be considered.

ABSTRACT

OBJECTIVES: To prospectively analyse robotically administered transperitoneal transversus abdominis plane (robot-assisted transversus abdominis plane [RTAP]) compared with both ultrasonography-guided transversus abdominis plane (UTAP) and local anaesthesia (LA) with regard to pain control and narcotic use in patients undergoing robot-assisted prostatectomy (RARP) or robot-assisted partial nephrectomy (RAPN). SUBJECTS/PATIENTS AND METHODS: Patients undergoing RARP or RAPN were randomized in a single-blind 2:2:1 fashion to RTAP:UTAP:LA, with the study powered to evaluate superiority of UTAP to LA and non-inferiority of RTAP to UTAP. We compared time to deliver the block, operating room time, postoperative pain scores using the visual analogue scale, and intra-operative and postoperative analgesia consumption. RESULTS: A total of 143 patients were randomized and received treatment. There was no significant difference in patient baseline characteristics. UTAP did not demonstrate superiority to LA in terms of pain control. RTAP and LA were faster to administer than UTAP (time to perform block 2.5 vs 2.5 vs 6.25 min; P < 0.001). There was no difference in postoperative narcotic, acetaminophen, ketorolac or ondansetron requirements among the three groups (P > 0.05). The study was terminated early due to the unexpected efficacy of LA. CONCLUSION: This study showed that UTAP and RTAP do not provide superior pain control to LA. The efficiency, effectiveness, and ease of administration of LA make it an excellent option for first-line therapy for postoperative analgesia.

ABSTRACT

PURPOSE: Minimally invasive partial nephrectomy (MIPN) and radical nephrectomy (MIRN) have successfully resulted in shorter length of stay (LOS) for patients. Using a national cohort, we compared 30-day outcomes of SDD (LOS = 0) versus standard-length discharge (SLD, LOS = 1-3) for MIRN and MIPN. METHODS: All patients who underwent MIPN (CPT 50,543) or MIRN (CPT 50,545) in the ACS-NSQIP database from 2012 to 2019 were reviewed. SDD and SLD groups were matched 1:1 by age, sex, race, body mass index, American Society of Anesthesiologists score, and medical comorbidities. We compared baseline characteristics, 30-day Clavien-Dindo (CD) complications, reoperations, and readmissions between SDD and SLD groups. Multivariable logistic regressions were used to evaluate predictors of adverse outcomes. RESULTS: 28,140 minimally invasive nephrectomy patients were included (SDD n = 237 [0.8%], SLD n = 27,903 [99.2%]). There were no significant differences in 30-day readmissions, CD I/II, CDIII, or CD IV complications before and after matching SDD and SLD groups. On multivariate regression analysis, SDD did not confer increased risk of 30-day complications or readmissions for both MIPN and MIRN. CONCLUSION: SDD after MIPN and MIRN did not confer increased risk of postoperative complications, reoperation, or readmission compared to SLD. Further research should explore optimal patient selection to ensure safe expansion of this initiative.

ABSTRACT

PURPOSE: Intravesical recurrence (IVR) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) has an incidence of approximately 20%-50%. Studies to date have been composed of mixed treatment cohorts-open, laparoscopic and robotic. The objective of this study is to assess clinicopathological risk factors for intravesical recurrence after RNU for UTUC in a completely minimally invasive cohort. MATERIALS AND METHODS: We performed a multicenter, retrospective analysis of 485 patients with UTUC without prior or concurrent bladder cancer who underwent robotic or laparoscopic RNU. Patients were selected from an international cohort of 17 institutions across the United States, Europe and Asia. Univariate and multiple Cox regression models were used to identify risk factors for bladder recurrence. RESULTS: A total of 485 (396 robotic, 89 laparoscopic) patients were included in analysis. Overall, 110 (22.7%) of patients developed IVR. The average time to recurrence was 15.2 months (SD 15.5 months). Hypertension was a significant risk factor on multiple regression (HR 1.99, CI 1.06; 3.71, p=0.030). Diagnostic ureteroscopic biopsy incurred a 50% higher chance of developing IVR (HR 1.49, CI 1.00; 2.20, p=0.048). Treatment specific risk factors included positive surgical margins (HR 3.36, CI 1.36; 8.33, p=0.009) and transurethral resection for bladder cuff management (HR 2.73, CI 1.10; 6.76, p=0.031). CONCLUSIONS: IVR after minimally invasive RNU for UTUC is a relatively common event. Risk factors include a ureteroscopic biopsy, transurethral resection of the bladder cuff, and positive surgical margins. When possible, avoidance of transurethral resection of the bladder cuff and alternative strategies for obtaining biopsy tissue sample should be considered.

ABSTRACT

PURPOSE: To compare functional outcomes of partial nephrectomy (PN) and active surveillance (AS) in oncocytoma. METHODS: Multicenter retrospective analysis of patients with oncocytoma managed with PN or AS (biopsy-confirmed). Primary outcome development of de novo chronic kidney disease (CKD) (eGFR < 60 mL/min/1.73m2). Cox regression Multivariable analysis (MVA) was carried out for predictors of de novo CKD. Linear regression was carried out for factors associated with increasing deltaGFR. Kaplan-Meier Analysis (KMA) was performed to analyze 5-year CKD-free survival. RESULTS: 295 patients were analyzed (224 PN/71 AS, median follow-up 37.4 months). No differences were noted for clinical tumor size (AS 2.6 vs. PN 2.9 cm, p = 0.108), and baseline eGFR (AS 79.6 vs. PN 77, p = 0.9670). Median change in tumor diameter for AS was 0.42 cm. Compared to PN, AS had deltaGFR (-15.3 vs. -6.4 mL/min/1.73m2, p < 0.001) and de novo CKD (28.2% vs. 12.1%, p = 0.002). AS patients who developed CKD had higher RENAL score (p = 0.005) and lower baseline eGFR (73 vs. 91.2 mL/min/1.73m2, p < 0.001) than AS patients who did not. MVA demonstrated increasing age (OR = 1.03, p = 0.025), tumor size (HR = 1.26, p = 0.032) and AS (HR = 4.91, p < 0.001) to be predictive for de novo CKD. Linear regression demonstrated AS was associated with larger decrease in deltaGFR (B = -0.219, p < 0.001). KMA revealed 5-year CKD survival was higher in PN (87%) vs. AS (62%, p < 0.001). CONCLUSION: AS was associated with greater functional decline than PN in oncocytoma. PN may be considered to optimalize renal functional preservation in select circumstances. Further investigation into mechanisms of functional decline in oncocytoma is requisite.

ABSTRACT

OBJECTIVE: To describe the natural history of untreated muscle-invasive bladder cancer (MIBC) and compare the oncological outcomes of treated and untreated patients. PATIENTS AND METHODS: We utilised a database encompassing all patients with newly diagnosed bladder cancer in Stockholm, Sweden between 1995 and 1996. The median follow-up for survivors was 14.4 years. Overall, 538 patients were diagnosed with bladder cancer of whom 126 had clinically localised MIBC. Patients were divided into two groups: those who received radical cystectomy or radiation therapy, and those who did not receive any form of treatment. Multivariable Cox or competing-risks regressions were adopted to predict metastasis, overall survival (OS), and cancer-specific mortality (CSM), when appropriate. Analyses were adjusted for age at diagnosis, sex, tumour stage, clinical N stage, and treatment. RESULTS: In all, 64 (51%) patients did not receive any definitive local treatment. In the untreated group, the median (interquartile range) age at diagnosis was 79 (63-83) vs 69 (63-74) years in the treated group (P < 0.001). Overall, 109 patients died during follow-up. At 6 months after diagnosis, 38% of the untreated patients had developed metastatic disease and 41% had CSM. The 5-year OS rate for untreated and treated patients was 5% (95% confidence interval [CI] 1, 12%) vs 48% (95% CI 36, 60%), respectively. Patients not receiving any treatment had a 5-year cumulative incidence of CSM of 86% (95% CI 75, 94%) vs 48% (95% CI 36, 60%) for treated patients. Untreated patients had a higher risk of progression to metastatic disease (hazard ratio [HR] 2.40, 95% CI 1.28, 4.51; P = 0.006), death from any cause (HR 2.63, 95% CI 1.65, 4.19; P < 0.001) and CSM (subdistribution HR 2.02, 95% CI 1.24, 3.30; P = 0.004). CONCLUSIONS: Untreated patients with MIBC are at very high risk of near-term CSM. These findings may help balance the risks vs benefits of integrating curative intent therapy particularly in older patients with MIBC.

ABSTRACT

This study aims to describe the acceptability and feasibility of an educational and training experiential intervention (ETEI) we developed to enhance muscle invasive bladder cancer (MIBC) patients with treatment decision-making and post-operative self-care. Twenty-five patients were randomized to a control group (N = 8) or ETEI group (N = 17). ETEI group participated in a nurse-led session on MIBC education. The control group received diet and nutrition education. Study questionnaires were completed at baseline and at 1-month post-intervention. Our results showed acceptable recruitment (58%) and retention rates (68%). The ETEI group reported increased knowledge (82% vs. 50%), improved decisional support (64% vs. 50%), improved communication (73% vs. 50%), and increased confidence in treatment decisions (73% vs. 50%) compared to the control group. Patients in the control group reported improved diet (50% v. 27%) as well as maintaining a healthy lifestyle (67% vs. 45%) compared to the ETEI group. Patients in the ETEI group reported a significant decrease in cancer worries and increases in self-efficacy beliefs over time compared to the control group. The ETEI was feasible, acceptable, and showed a potential for inducing desired changes in cancer worries and efficacy beliefs.

ABSTRACT

BACKGROUND: Achieving a pathologic complete response (pCR) with neoadjuvant chemotherapy (NAC) in patients with muscle-invasive bladder cancer (MIBC) has been associated with improved overall survival (OS). This study was aimed at evaluating the impact of pathologic downstaging (pDS; ie, a pT stage at least 1 stage lower than the pre-NAC cT stage) on the OS of patients with MIBC treated with NAC. METHODS: The Retrospective International Study of Cancers of the Urothelial Tract (RISC) and the National Cancer Database (NCDB) were queried for cT2-4N0M0 patients treated with NAC. A multivariable Cox model including either pDS or pCR was generated. A nested model was built to evaluate the added value of pDS (excluding patients achieving a pCR) to a model including pCR alone. C indices were computed to assess discrimination. NCDB was used for validation. The treatment effect of NAC versus cystectomy alone in achieving pDS was estimated through an inverse probability-weighted regression adjustment. RESULTS: Overall, 189 and 2010 patients from the RISC and NCDB cohorts, respectively, were included; pDS and pCR were achieved by 33% and 35% and by 20% and 15% in RISC and NCDB, respectively. In both data sets, pDS and pCR were associated with better OS and C indices. Adding pDS excluding pCR to the model with pCR fit the data better (likelihood ratio, P = .019 for RISC and P < .001 for NCDB), and it yielded better discrimination (incremental C index, 4.2 for RISC and 1.6 for NCDB). The treatment effect of NAC in achieving pDS was 2.07-fold (P < .001) in comparison with cystectomy alone. CONCLUSIONS: A decrease of at least 1 stage from the cT stage to the pT stage is associated with improved OS in patients with MIBC treated with NAC.

ABSTRACT

Open radical nephroureterectomy (NU) with removal of the ureter and bladder cuff is the 'gold standard' in the treatment of high-grade urothelial cancers of the upper urinary tract. A salient issue is the management of the distal ureter and bladder cuff at time of surgery. Which technique confers superior oncologic benefit is of particular interest since this disease process is notoriously plagued with high intravesical recurrence rates. Although open radical NU is the 'gold standard', the maturation of minimally invasive surgery formidably challenges approaches considered 'gold standard'. We thus sought to critically review the literature comparing perioperative and oncologic outcomes in the approaches used to manage the distal ureter and bladder cuff in patients undergoing radical NU.

ABSTRACT

Adrenocortical carcinoma (ACC) is a rare malignancy associated with poor prognosis despite available treatments. In patients with localized or locally advanced disease, complete resection with negative margins offers the only potential for cure. Unfortunately, most patients develop local and distant recurrence following initial resection highlighting the importance of meticulous surgical technique in the hands of an experienced surgeon. While minimally invasive surgery (MIS) has supplanted open surgery for small to medium-sized benign adrenal tumors, controversy surrounds the use of MIS for resection of ACC. We sought to provide an overview of the key oncological principles in the surgical management of ACC and to critically review the literature comparing outcomes between the open and MIS approaches.
