Why do men reject adjuvant radiotherapy following radical prostatectomy? A systematic survey.

Purpose To investigate non-adherence rates to adjuvant radiotherapy (aRT) after radical prostatectomy (RP) and to obtain patient reported reasons for rejecting aRT despite recommendation by a multidisciplinary team discussion (MTD). Methods In a retrospective monocentric analysis, we identified 1197 prostate cancer patients who underwent RP between 2014-2022 at our institution, of which 735 received a postoperative MTD recommendation. Patients with a recommendation for aRT underwent a structured phone interview with predefined standardised qualitative and quantitative questions and were stratified into "adherent" (aRT performed) and "non-adherent" groups (aRT not performed). Results Of 55 patients receiving a recommendation for aRT (7.5% of all RP patients), 24 (44%) were non-adherent. Baseline tumour characteristics were comparable among the groups. "Fear of radiation damage" was the most common reason for rejection, followed by "lack of information", "feeling that the treating physician does not support the recommendation" and "the impression that aRT is not associated with improved oncological outcome". Salvage radiotherapy (sRT) was performed in 25% of non-adherent patients. Conclusion High rates of non-adherence to aRT after RP were observed, and reasons for this phenomenon are most likely multifactorial. Multidisciplinary and individualized patient counselling might be a key for increasing adherence rates.

Prevalence of reported penicillin allergy and associations with perioperative complications, length of stay, and cost in patients undergoing elective cancer surgery.

Objective: Up to 10% of patients report penicillin allergy (PA), although only 1% are truly affected by Ig-E-mediated allergies. PA has been associated with worse postoperative outcomes, but studies on the impact of reported PA in cancer patients are lacking, and especially in these multimorbid patients, a non-complicated course is of utmost importance. Methods: Retrospective analysis of patients undergoing elective oncological surgery at a tertiary reference center. Data on surgical site infections (SSI), postoperative complications (measured by Clavien-Dindo classification and Comprehensive Complication Index (CCI)), hospitalization duration, and treatment costs were collected. Results: Between 09/2019 and 03/2020, 152 patients were identified. 16/152 patients (11%) reported PA, while 136/152 (89%) did not. There were no differences in age, BMI, Charlson Comorbidity Index, and smoking status between groups (p > 0.4). Perioperative beta-lactam antibiotics were used in 122 (89.7%) and 15 (93.8%) patients without and with reported PA, respectively. SSI and mean numbers of infections occurred non-significantly more often in patients with PA (p = 0.2 and p = 0.47). The median CCI was significantly higher in PA group (26 vs. 51; p = 0.035). The median hospitalization duration and treatment costs were similar between non-PA and PA groups (4 vs 3 days, p = 0.8; 16'818 vs 17'444 CHF, p = 0.4). Conclusions: In patients undergoing cancer surgery, reported PA is common. Failure to question the unproven PA may impair perioperative outcomes. For this reason, patient and provider education on which reactions constitute a true allergy would also assist in allergy de-labeling. In addition, skin testing and oral antibiotic challenges can be performed to identify the safe antibiotics and to de-label appropriate patients.

Comparing Oncological and Perioperative Outcomes of Open versus Laparoscopic versus Robotic Radical Nephroureterectomy for the Treatment of Upper Tract Urothelial Carcinoma: A Multicenter, Multinational, Propensity Score-Matched Analysis.

OBJECTIVES: To identify correlates of survival and perioperative outcomes of upper tract urothelial carcinoma (UTUC) patients undergoing open (ORNU), laparoscopic (LRNU), and robotic (RRNU) radical nephroureterectomy (RNU). METHODS: We conducted a retrospective, multicenter study that included non-metastatic UTUC patients who underwent RNU between 1990-2020. Multiple imputation by chained equations was used to impute missing data. Patients were divided into three groups based on their surgical treatment and were adjusted by 1:1:1 propensity score matching (PSM). Survival outcomes per group were estimated for recurrence-free survival (RFS), bladder recurrence-free survival (BRFS), cancer-specific survival (CSS), and overall survival (OS). Perioperative outcomes: Intraoperative blood loss, hospital length of stay (LOS), and overall (OPC) and major postoperative complications (MPCs; defined as Clavien-Dindo > 3) were assessed between groups. RESULTS: Of the 2434 patients included, 756 remained after PSM with 252 in each group. The three groups had similar baseline clinicopathological characteristics. The median follow-up was 32 months. Kaplan-Meier and log-rank tests demonstrated similar RFS, CSS, and OS between groups. BRFS was found to be superior with ORNU. Using multivariable regression analyses, LRNU and RRNU were independently associated with worse BRFS (HR 1.66, 95% CI 1.22-2.28, p = 0.001 and HR 1.73, 95%CI 1.22-2.47, p = 0.002, respectively). LRNU and RRNU were associated with a significantly shorter LOS (beta -1.1, 95% CI -2.2-0.02, p = 0.047 and beta -6.1, 95% CI -7.2-5.0, p < 0.001, respectively) and fewer MPCs (OR 0.5, 95% CI 0.31-0.79, p = 0.003 and OR 0.27, 95% CI 0.16-0.46, p < 0.001, respectively). CONCLUSIONS: In this large international cohort, we demonstrated similar RFS, CSS, and OS among ORNU, LRNU, and RRNU. However, LRNU and RRNU were associated with significantly worse BRFS, but a shorter LOS and fewer MPCs.

Is conservative management safe in patients with acute ureterolithiasis and perirenal stranding?

In patients presenting with ureterolithiasis, perirenal stranding is frequently observed in non-contrast computed tomography. Because perirenal stranding may be caused by tears in the collecting system, previous studies have described an increased risk of infectious complications and suggested broad empiric antibiotic therapy and immediate decompressing of the upper urinary tract. We hypothesized that these patients can also be managed conservatively. Therefore, we retrospectively identified patients with ureterolithiasis and perirenal stranding and compared diagnostic and treatment characteristics as well as treatment outcomes between patients undergoing conservative versus interventional management by ureteral stenting, percutaneous drainage or primary ureteroscopic stone removal. We classified perirenal stranding as mild, moderate or severe based on its radiological extent. Of 211 patients, 98 were managed conservatively. Patients in the interventional group had larger ureteral stones, more proximal ureteral stone location, more severe perirenal stranding, higher systemic and urinary infectious parameters, higher creatinine levels, and received more frequent antibiotic therapy. The conservatively managed group experienced a spontaneous stone passage rate of 77%, while 23% required delayed intervention. In the interventional and conservative groups, 4% and 2% of patients, respectively, developed sepsis. None of the patients in either group developed a perirenal abscess. Comparison of perirenal stranding grade between mild, moderate and severe in the conservatively treated group showed no difference in the spontaneous stone passage and infectious complications. In conclusion, conservative management without prophylactic antibiotics for ureterolithiasis and perirenal stranding is a valid treatment option as long as no clinical or laboratory signs of renal failure or infections are observed.

Predictive and Prognostic Role of the Neutrophil-to-Lymphocyte Ratio in Muscle Invasive Bladder Cancer Treated With Neoadjuvant Chemotherapy and Radical Cystectomy.

INTRODUCTION: There is a persistent lack of validated biomarkers that identify patients most likely to benefit from neoadjuvant chemotherapy (NAC) in urothelial carcinoma of the bladder (UCB). Therefore, the purpose of this study was to investigate the predictive and prognostic impact of the pretreatment neutrophil-to-lymphocyte ratio (NLR) in UCB patients treated with NAC and radical cystectomy (RC). PATIENTS AND METHODS: We conducted a retrospective analysis of an international-multicenter database comprising 404 UCB patients staged cT2-4N0-3M0. The cohort was split into low and high NLR using an optimal cutoff value determined by maximizing Youden's index. Logistic and Cox regression analyses were performed with respect to several clinical endpoints. The discriminative ability of the models and the additive discriminative value of NLR was assessed by calculating the area under receiver operating characteristics curves, C-index, and decision curve analysis (DCA). RESULTS: A total of 169 patients (41.8%) had a high NLR, which was associated with a decreased probability of complete response (CR, OR: 0.24 [95% CI, 0.13-0.42], P < .001) and/or partial response (PR, OR: 0.33 [95% CI, 0.21-0.49], P < .001). Adding the NLR to predictive reference models significantly improved their accuracy for the prediction of both CR and PR. A high NLR was associated with poor survival outcomes in the pretreatment setting, however, it didn't meaningfully change the C-index based on the model. CONCLUSION: We confirmed that an elevated NLR is an independent and clinically significant predictor of response to NAC and adverse pathological features in UCB treated with NAC plus RC. The accuracy of this biomarker in the age of immunotherapy warrants further evaluation.

Diagnostic Accuracy of Clinical Lymph Node Staging for Upper Tract Urothelial Cancer Patients: A Multicenter, Retrospective, Observational Study.

PURPOSE: Treatment options for the management of upper tract urothelial cancer are based on accurate staging. However, the performance of conventional cross-sectional imaging for clinical lymph node staging (N-staging) remains poorly investigated. This study aims to evaluate the diagnostic accuracy of conventional cross-sectional imaging for upper tract urothelial cancer N-staging. MATERIALS AND METHODS: This study was a multicenter, retrospective, observational study. We included 865 nonmetastatic (M0) upper tract urothelial cancer patients treated with curative intended surgery and lymph node dissection who had been staged with conventional cross-sectional imaging before surgery. We compared clinical (c) and pathological (p) N-staging results to evaluate the concordance of node-positive (N+) and node-negative (N0) disease and calculate cN-staging's diagnostic accuracy. RESULTS: Conventional cross-sectional imaging categorized 750 patients cN0 and 115 cN+. Lymph node dissection categorized 641 patients pN0 and 224 pN+. The cN-stage was pathologically downstaged in 6.8% of patients, upstaged in 19%, and found concordant in 74%. The sensitivity and specificity of cN-staging were 25% (95% CI 20; 31) and 91% (95% CI 88; 93). Positive and negative likelihood ratios were 2.7 (95% CI 2.0; 3.8) and 0.83 (95% CI 0.76; 0.89). The area under the receiver operating characteristics curve (0.58, 95% CI 0.55; 0.61) revealed low diagnostic accuracy. CONCLUSIONS: Conventional cross-sectional imaging had low sensitivity in detecting upper tract urothelial cancer pN+ disease. However, cN+ increased the likelihood of pN+ by almost threefold. Thus, conventional cross-sectional imaging is a rule-in but not a rule-out test. Lymph node dissection should remain the standard during extirpative upper tract urothelial cancer surgery to obtain accurate N-staging. cN+ could be a strong argument for early systemic treatment.

The Role of Additional Epididymis Resection during Hydrocelectomy: Is It of Any Benefit in Comparison to Simple Hydrocelectomy?

INTRODUCTION: Open hydrocelectomy via scrotal incision is the standard approach for secondary hydroceles. Traditionally, the Swiss urologic community offer hydrocelectomy with additional resection of the epididymis in elderly men with completed family planning. It is believed that the additional resection of the epididymis reduces the postoperative recurrence rate of hydroceles. However, there is no evidence supporting this theory. Therefore, the aim of this study was to compare the recurrence and complication rates for patients with secondary hydroceles undergoing either pure hydrocelectomy (puH) or hydrocelectomy with additional resection of the epididymis (HRE). MATERIALS AND METHODS: We reviewed all male patients who underwent surgical therapy for secondary hydroceles between May 2003 and February 2019 at our institution. Patient's baseline and perioperative characteristics as well as postoperative characteristics including complications and recurrence rates were gathered and compared between different surgical techniques. RESULTS: A total of 234 patients were identified. puH was performed in 93 (40%) cases and HRE in 141 (60%) patients. Patients in the HRE group were older (median age: 62 vs. 38 years, p < 0.001), had a higher ASA-Score (p < 0.001), were more often on platelet aggregation inhibitors (19% vs. 7.5%, p = 0.01), and had a longer median operative time (75 vs. 64 min, p < 0.001). During a median follow-up of 46 months, a similar number of recurrent hydroceles were found for puH (7 [7.5%]) and HRE (6 [4.5%]) (p = 0.3). Complications were observed in 19 (20%) cases after puH compared to 25 (18%) cases after HRE (p = 0.6). Patients after puH experienced more often severe complications (Clavien-Dindo Grade 3b) compared to the HRE group (5 vs. 12%, p = 0.046). CONCLUSION: puH and HRE showed similar results in terms of overall low recurrence rates and also in terms of postoperative complications, even though patients who underwent puH experienced slightly higher severe complications. Both procedures are safe and effective, but it seems that HRE does not provide a relevant clinical benefit in comparison to puH for the management of men with secondary hydroceles.

Quality indicators for the management of muscle-invasive bladder cancer in the perioperative setting of radical cystectomy: a narrative review.

Background and Objective: Identifying evidence-based and measurable quality-of-care indicators is crucial for optimal management of patients requiring radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). RC with urinary diversion and lymphadenectomy is the standard treatment for patients with MIBC. Preoperatively, neoadjuvant chemotherapy (NAC) with cisplatin-based combinations improves survival outcomes and is the recommended standard of care for eligible patients. Intraoperatively, lymph node dissection (LND) by, at least, following a standard pelvic lymph node template improves overall- and recurrence-free survival and allows for accurate tumour staging. Avoiding positive soft tissue surgical margins (STSM) should be a main target intraoperatively since they are almost universally associated with mortality. Implementing enhanced recovery after surgery (ERAS) programs can reduce lengths of hospital stay (LOS) and postoperative complication rates without increasing readmission rates after RC. Moreover, several studies have shown that smoking negatively affects local and systemic treatment outcomes in bladder cancer (BC) patients. Therefore, smoking cessation counselling for smokers should be an essential part of bladder cancer management regardless of the disease state. Methods: We performed a comprehensive, non-systematic review of the latest literature to define indicators representing the best evidence available for optimal care of MIBC patients treated with RC. Key Content and Findings: In this review, we propose five major quality indicators that are easily implementable for optimized management of MIBC patients treated with RC, including: usage of cisplatin-based NAC in eligible patients, ensurance of negative STSM, performance of (at least) a standard pelvic template LND, implementation of ERAS strategies, and professional smoking cessation counselling. Conclusions: Optimal management of MIBC needs to be framed by evidence-based, reproducible, and measurable quality indicators that will allow for guidance and comparative effectiveness assessment of clinical practices; adherence to them is likely to improve patients' prognoses by a tensible margin. For the treatment of MIBC patients with RC, we identified five essential quality indicators. Keywords: Assessment; bladder cancer (BC); muscle-invasive bladder cancer (MIBC); cystectomy; radical cystectomy (RC); quality.

Comparative Outcomes of Primary Versus Recurrent High-risk Non-muscle-invasive and Primary Versus Secondary Muscle-invasive Bladder Cancer After Radical Cystectomy: Results from a Retrospective Multicenter Study.

Background: Radical cystectomy (RC) is indicated in primary or secondary muscle-invasive bladder cancer (primMIBC, secMIBC) and in primary or recurrent high- or very high-risk non-muscle-invasive bladder cancer (primHR-NMIBC, recHR-NMIBC). The optimal timing for RC along the disease spectrum of nonmetastatic urothelial carcinoma remains unclear. Objective: To compare outcomes after RC between patients with primHR-NMIBC, recHR-NMIBC, primMIBC, and secMIBC. Design setting and participants: This retrospective, multicenter study included patients with clinically nonmetastatic bladder cancer (BC) treated with RC. Outcome measurements and statistical analysis: We assessed oncological outcomes for patients who underwent RC according to the natural history of their BC. primHR-NMIBC and primMIBC were defined as no prior history of BC, and recHR-NMIBC and secMIBC as previously treated NMIBC that recurred or progressed to MIBC, respectively. Log-rank analysis was used to compare survival outcomes, and univariable and multivariable Cox and logistic regression analyses were used to identify predictors for survival. Results and limitations: Among the 908 patients included, 211 (23%) had primHR-NMIBC, 125 (14%) had recHR-NMIBC, 404 (44%) had primMIBC, and 168 (19%) had secMIBC. Lymph node involvement and pathological upstaging were more frequent in the secMIBC group than in the other groups (p < 0.001). The median follow-up was 37 mo. The 5-year recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) were 77.9%, 83.2%, and 72.7% in primHR-NMIBC, 60.0%, 59%, and 48.9% in recHR-NMIBC, 60.9%, 64.5%, and 54.8% in primMIBC, and 41.3%, 46.5%, and 39% in secMIBC, respectively, with statistically significant differences across all survival outcomes except between recHR-NMIBC and primMIBC. On multivariable Cox regression, recHR-NMIBC was independently associated with shorter RFS (hazard ratio [HR] 1.64; p = 0.03), CSS (HR 1.79; p = 0.01), and OS (HR 1.45; p = 0.03), and secMIBC was associated with shorter CSS (HR 1.77; p = 0.01) and OS (HR 1.57; p = 0.006). Limitations include the biases inherent to the retrospective study design. Conclusions: Patients with recHR-NMIBC and primHR-MIBC had similar survival outcomes, while those with sec-MIBC had the worst outcomes. Therefore, early radical intervention may be indicated in selected patients, and potentially neoadjuvant systemic therapies in some patients with recHR-NMIBC. Patient summary: We compared cancer outcomes in different bladder cancer scenarios in a large, multinational series of patients who underwent removal of the bladder with curative intent. We found that patients who experienced recurrence of non-muscle-invasive bladder cancer (NMIBC) had similar survival outcomes to those with initial muscle-invasive bladder cancer (MIBC), while patients who experienced progression of NMIBC to MIBC had the worst outcomes. Selected patients with non-muscle-invasive disease may benefit from early radical surgery or from perioperative chemotherapy or immunotherapy.

Radiation therapy compared to radical prostatectomy as first-line definitive therapy for patients with high-risk localised prostate cancer: An updated systematic review and meta-analysis.

Objective: To present an update of the available literature on external beam radiation therapy (EBRT) with or without brachytherapy (BT) compared to radical prostatectomy (RP) for patients with high-risk localised prostate cancer (PCa). Methods: We conducted a systematic review and meta-analysis of the literature assessing the survival outcomes in patients with high-risk PCa who received EBRT with or without BT compared to RP as the first-line therapy with curative intent. We queried PubMed and Web of Science database in January 2021. Moreover, we used random or fixed-effects meta-analytical models in the presence or absence of heterogeneity per the I2 statistic, respectively. We performed six meta-analyses for overall survival (OS) and cancer-specific survival (CSS). Results: A total of 27 studies were selected with 23 studies being eligible for both OS and CSS. EBRT alone had a significantly worse OS and CSS compared to RP (hazard ratio [HR] 1.38, 95% confidence interval [CI] 1.16-1.65; and HR 1.55, 95% CI 1.25-1.93). However, there was no difference in OS (HR 1.1, 95% CI 0.76-1.34) and CSS (HR 0.69, 95% CI 0.45-1.06) between EBRT plus BT compared to RP. Conclusion: While cancer control affected by EBRT alone seems inferior to RP in patients with high-risk PCa, BT additive to EBRT was not different from RP. These data support the need for BT in addition to EBRT as part of multimodal RT for high-risk PCa.Abbreviations: ADT: androgen-deprivation therapy; BT: brachytherapy; CSS: cancer-specific survival; HR: hazard ratio; MFS, metastatic-free survival; MOOSE: Meta-analyses of Observational Studies in Epidemiology; OR: odds ratio; OS: overall survival; PCa: prostate cancer; RR: relative risk; RP: radical prostatectomy; RCT: randomised controlled trials; (EB)RT: (external beam) radiation therapy.

Hematological prognosticators in metastatic renal cell cancer treated with immune checkpoint inhibitors: a meta-analysis.

Aim: We aimed to assess the prognostic value of pretreatment hematological biomarkers in patients with metastatic renal cell carcinoma (mRCC) treated with immune checkpoint inhibitors (ICIs). Methods: PubMed, Web of Science and Scopus databases were searched for articles according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Results: Fifteen studies comprising 1530 patients were eligible for meta-analysis. High levels of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein and lactate dehydrogenase were significantly associated with worse progression-free survival. High NLR and PLR were significantly associated with worse overall survival. Conclusion: High pretreatment NLR and PLR appear to be hematological prognostic factors of progression and overall mortality in mRCC patients treated with ICIs. These findings might help in the design of correlative biomarker studies to guide the clinical decision-making in the immune checkpoint inhibitor era.

Identifying the predictive/prognostic factors that can be applied to daily clinical practice is mandatory to facilitate the use of immune checkpoint inhibitors. Some pretreatment hematological markers used in daily clinical practice appear to be prognostic factors in metastatic renal cell carcinoma patients treated with immune checkpoint inhibitors. We believe that the findings of the present meta-analysis might help researchers to design prospective correlative biomarker studies to guide clinical decision-making in the immunotherapy era.

Prognostic impact of insulin-like growth factor-I and its binding proteins, insulin-like growth factor-I binding protein-2 and -3, on adverse histopathological features and survival outcomes after radical cystectomy.

OBJECTIVES: Insulin-like growth factor-I and its binding proteins are involved in cancer development, progression, and metastasis. In urothelial carcinoma, the impact of this pathway is still poorly investigated. The present large cohort study aimed to evaluate the association of preoperative circulating levels of insulin-like growth factor-I, insulin-like growth factor-I binding protein-2 and -3 on outcomes after radical cystectomy. METHODS: A retrospective cohort study of the plasma specimens from 1036 consecutive urothelial carcinoma patients who were treated with radical cystectomy. The primary and secondary outcomes were adverse histopathological features and survival outcomes. Binominal logistic regression and multivariable Cox regression analyses were performed to assess the association of plasma levels of insulin-like growth factor-I, insulin-like growth factor-I binding protein-2 and -3 with outcomes. RESULTS: On multivariable analysis adjusting for the effects of preoperative variables, lower insulin-like growth factor-I binding protein-2 levels were associated with an increased risk of lymph node metastasis and (any non-organ confined disease) any non-organ confined disease. Insulin-like growth factor-I binding protein-3 levels were also inversely independently associated with lymph node metastasis. Receiver operating characteristic curve analysis showed that the addition of insulin-like growth factor-I binding proteins biomarkers to a reference model significantly improved the discriminating ability for the prediction of lymph node metastasis (+10.0%, P < 0.001). On multivariable Cox regression models, lower levels of both insulin-like growth factor-I binding protein-2 and -3 plasma levels were associated with recurrence-free survival, cancer-specific survival, and overall survival. insulin-like growth factor-I binding protein-2 and -3 levels and improved the discrimination of a standard reference model for the prediction of recurrence-free survival, cancer-specific survival, and overall survival (+4.9%, 4.9%, 2.3%, respectively). CONCLUSIONS: Preoperative insulin-like growth factor-I binding protein-2 and -3 are significantly associated with features of biologically and clinically aggressive urothelial carcinoma. These biomarkers improved prognostic urothelial carcinoma models.

Risk factors for concomitant positive midstream urine culture in patients presenting with symptomatic ureterolithiasis.

In patients with symptomatic ureterolithiasis, immediate treatment of concomitant urinary tract infection (UTI) may prevent sepsis. However, urine cultures require at least 24 h to confirm or exclude UTI, and therefore, clinical variables may help to identify patients who require immediate empirical broad-spectrum antibiotics and surgical intervention. Therefore, we divided a consecutive cohort of 705 patients diagnosed with symptomatic ureterolithiasis at a single institution between 2011 and 2017 into a training (80%) and a testing cohort (20%). A machine-learning-based variable selection approach was used for the fitting of a multivariable prognostic logistic regression model. The discriminatory ability of the model was quantified by the area under the curve (AUC) of receiver-operating curves (ROC). After validation and calibration of the model, a nomogram was created, and decision curve analysis (DCA) was used to evaluate the clinical net-benefit. UTI was observed in 40 patients (6%). LASSO regression selected the variables elevated serum CRP, positive nitrite, and positive leukocyte esterase for fitting of the model with the highest discriminatory ability. In the testing cohort, model performance evaluation for prediction of UTI showed an AUC of 82 (95% CI 71.5-95.7%). Model calibration plots showed excellent calibration. DCA showed a clinically meaningful net-benefit between a threshold probability of 0 and 80% for the novel model, which was superior to the net-benefit provided by either one of its singular components. In conclusion, we developed and internally validated a logistic regression model and a corresponding highly accurate nomogram for prediction of concomitant positive midstream urine culture in patients presenting with symptomatic ureterolithiasis.

Pentafecta for Radical Nephroureterectomy in Patients with High-Risk Upper Tract Urothelial Carcinoma: A Proposal for Standardization of Quality Care Metrics.

Background: Measuring quality of care indicators is important for clinicians and decision making in health care to improve patient outcomes. Objective: The primary objective was to identify quality of care indicators for patients with upper tract urothelial carcinoma (UTUC) and to validate these in an international cohort treated with radical nephroureterectomy (RNU). The secondary objective was to assess the factors associated with failure to validate the pentafecta. Design: We performed a retrospective multicenter study of patients treated with RNU for EAU high-risk (HR) UTUC. Outcome measurements and statistical analysis: Five quality indicators were consensually approved, including a negative surgical margin, a complete bladder-cuff resection, the absence of hematological complications, the absence of major complications, and the absence of a 12-month postoperative recurrence. After multiple imputations and propensity-score matching, log-rank tests and a Cox regression were used to assess the survival outcomes. Logistic regression analyses assessed predictors for pentafecta failure. Results: Among the 1718 included patients, 844 (49%) achieved the pentafecta. The median follow-up was 31 months. Patients who achieved the pentafecta had superior 5-year overall- (OS) and cancer-specific survival (CSS) compared to those who did not (68.7 vs. 50.1% and 79.8 vs. 62.7%, respectively, all p < 0.001). On multivariable analyses, achieving the pentafecta was associated with improved recurrence-free survival (RFS), CSS, and OS. No preoperative clinical factors predicted a failure to validate the pentafecta. Conclusions: Establishing quality indicators for UTUC may help define prognosis and improve patient care. We propose a pentafecta quality criteria in RNU patients. Approximately half of the patients evaluated herein reached this endpoint, which in turn was independently associated with survival outcomes. Extended validation is needed.

Prognostic Role of Preoperative Vascular Cell Adhesion Molecule-1 Plasma Levels in Urothelial Carcinoma of the Bladder Treated With Radical Cystectomy.

BACKGROUND: Angiogenesis-related marker vascular cell adhesion molecule-1 (VCAM-1) has been shown to be elevated in urothelial carcinoma of the bladder (UCB), but its predictive/prognostic role has not been determined. Thus, this study aimed to investigate the predictive/prognostic role of VCAM-1 for patients who have UCB treated with radical cystectomy (RC). METHODS: The study enrolled 1036 patients with clinically non-metastatic advanced UCB who underwent RC, and plasma VCAM-1 was evaluated preoperatively. The correlation of plasma VCAM-1 with pathologic and survival outcomes was assessed using binominal logistic regression and multivariable Cox regression analyses. Discrimination was assessed using the area under the curve and concordance indices. The clinical net benefit was evaluated using decision curve analysis (DCA). RESULTS: Preoperative VCAM-1 was significantly elevated in patients with adverse pathologic features. Higher VCAM-1 levels were independently associated with increased risk of lymph-node-metastasis (LNM), ≥pT3 disease, and non-organ-confined disease (NOCD (p < 0.001 for each). Preoperative plasma VCAM-1 was independently associated with recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) in pre- and postoperative multivariable models. Adding VCAM-1 to these predictive models improved their discriminatory ability to predict all outcomes by a significant margin. In the DCA, VCAM-1 addition to the reference models for prediction of LNM, NOCD, RFS, and CSS resulted in relevant improvement. CONCLUSIONS: Elevated plasma VCAM-1 was associated with biologically and clinically aggressive UCB disease features. After validation, preoperative VCAM-1 may serve as a biomarker to help identify patients likely to benefit from intensified/multimodal therapy. In addition, VCAM-1 improved the discriminatory power of predictive/prognostic models and can be used to refine personalized clinical decision-making.

Neoadjuvant Chemotherapy in Elderly Patients With Upper Tract Urothelial Cancer: Oncologic Outcomes From a Multicenter Study.

INTRODUCTION: Although upper tract urothelial carcinoma (UTUC) is more common in the elderly, outcomes of neoadjuvant chemotherapy (NAC) in this population have never been explored. The objective of the study was to assess the impact of NAC on pathologic response and oncological outcomes stratified by age. PATIENTS AND METHODS: This multicenter study included 164 patients treated with NAC and radical nephroureterectomy (RNU) for clinically non-metastatic, high-risk UTUC. The cohort was stratified into two groups according to median age. Patients received either cisplatin-based or non-cisplatin-based chemotherapies. Pathologic responses were defined as pathologic objective response (pOR; ≤ ypT1N0) and pathologic complete response (pCR; ypT0N0). Univariable and multivariable logistic and Cox regression analyses were performed to identify predictors for pathologic response and survival outcomes. RESULTS: The cohorts' median age was 68 years with the elderly group (> 68 years) comprising 74 patients. Neoadjuvant chemotherapy included methotrexate-vinblastine-doxorubicin-cisplatin (MVAC) in 66 (40%), gemcitabine cisplatin (GC) in 66 (40%) and non-cisplatin chemotherapy in 32 patients (20%). Younger patients received more often MVAC (50% vs. 28%) while elderly received more GC (34% vs. 47%) or non-cisplatin chemotherapy (16% vs. 24%) (P = .02). Overall, pOR and pCR were similar across age groups (52% vs. 47%; P = .5 and 10% vs. 8%; P = .7). While GC and non-cisplatin chemotherapy showed a lower pCR of 5% and 3%, respectively, MVAC revealed a pCR of 17% (P = .03) and was independently associated with a higher pCR (OR 4.31; P = .03). Kaplan-Meier analysis showed no difference in recurrence-free and cancer-specific survival, whereas a lower rate was seen in overall survival for the elderly. CONCLUSION: Elderly patients with high-risk UTUC eligible for cisplatin-based NAC prior to RNU may benefit from this multimodal therapy equally as their younger counterparts. Cisplatin-ineligible patients undergoing non-cisplatin-based NAC appeared to have lower response rates and should be considered for immediate RNU.

Comparison of short-term and long-term neoadjuvant hormone therapy prior to radical prostatectomy: a systematic review and meta-analysis.

PURPOSE: This study aimed to evaluate the efficacy of long-term neoadjuvant androgen-deprivation therapy (ADT) before radical prostatectomy (RP). METHODS: We conducted meta-analyses and network meta-analyses, which included randomized controlled trials that assessed patients with prostate cancer (PC) who received either short-term (<6 months) or long-term (≥6 months) neoadjuvant ADT before RP. RESULTS: Thirteen articles with 2778 patients were eligible for analysis. Short-term neoadjuvant ADT was neither associated with biochemical recurrence (OR 1.19, 95% CI, 0.93-1.51, p = 0.17), metastasis (OR 0.73, 95% CI, 0.45-1.19, p = 0.21), nor overall mortality (OR 0.72, 95% CI 0.43-1.21, p = 0.22); no study investigated survival outcomes in patients on long-term neoadjuvant ADT. In terms of pathologic outcomes, long-term neoadjuvant ADT was significantly associated with a reduced risk of positive surgical margin (SM) and an increased rate of organ-confined disease (OCD) compared to short-term neoadjuvant ADT (OR 0.56, 95% CI 0.39-0.80, p = 0.001, and OR 1.48, 95% CI 1.10-1.99, p = 0.009, respectively). These findings were confirmed in the network meta-analyses. Meanwhile, only a non-significant trend favoring long-term neoadjuvant ADT was observed for pathologic complete response (OR 1.98, 95% Crl 1.00-3.93). CONCLUSION: Long-term neoadjuvant ADT was associated with more favorable pathologic outcomes, but whether these findings translate into favorable survival outcomes still remains unproven due to very limited evidence. Since there are no reliable survival data, long-term neoadjuvant ADT before RP should not be used in clinical practice until more robust evidence arises from ongoing trials.

Influence of steep Trendelenburg position on postoperative complications: a systematic review and meta-analysis.

Intraoperative physiologic changes related to the steep Trendelenburg position have been investigated with the widespread adoption of robot-assisted pelvic surgery (RAPS). However, the impact of the steep Trendelenburg position on postoperative complications remains unclear. We conducted a meta-analysis to compare RAPS to laparoscopic/open pelvic surgery with regards to the rates of venous thromboembolism (VTE), cardiac, and cerebrovascular complications. Meta-regression was performed to evaluate the influence of confounding risk factors. Ten randomized controlled trials (RCTs) and 47 non-randomized controlled studies (NRSs), with a total of 380,125 patients, were included. Although RAPS was associated with a decreased risk of VTE and cardiac complications compared to laparoscopic/open pelvic surgery in NRSs [risk ratio (RR), 0.59; 95% CI 0.51-0.72, p < 0.001 and RR 0.93; 95% CI 0.58-1.50, p = 0.78, respectively], these differences were not confirmed in RCTs (RR 0.92; 95% CI 0.52-1.62, p = 0.77 and RR 0.93; 95% CI 0.58-1.50, p = 0.78, respectively). In subgroup analyses of laparoscopic surgery, there was no significant difference in the risk of VTE and cardiac complications in both RCTs and NRSs. In the meta-regression, none of the risk factors were found to be associated with heterogeneity. Furthermore, no significant difference was observed in cerebrovascular complications between RAPS and laparoscopic/open pelvic surgery. Our meta-analysis suggests that the steep Trendelenburg position does not seem to affect postoperative complications and, therefore, can be considered safe with regard to the risk of VTE, cardiac, and cerebrovascular complications. However, proper individualized preventive measures should still be implemented during all surgeries including RAPS to warrant patient safety.

Prognostic value of hepatocyte growth factor for muscle-invasive bladder cancer.

PURPOSE: The HGF/MET pathway is involved in cell motility, angiogenesis, proliferation, and cancer invasion. We assessed the clinical utility of plasma HGF level as a prognostic biomarker in patients with MIBC. METHODS: We retrospectively analyzed 565 patients with MIBC who underwent radical cystectomy. Logistic regression and Cox regression models were used, and predictive accuracies were estimated using the area under the curve and concordance index. To estimate the clinical utility of HGF, DCA and MCID were applied. RESULTS: Plasma HGF level was significantly higher in patients with advanced pathologic stage and LN metastasis (p = 0.01 and p < 0.001, respectively). Higher HGF levels were associated with an increased risk of harboring LN metastasis and non-organ-confined disease (OR1.21, 95%CI 1.12-1.32, p < 0.001, and OR1.35, 95%CI 1.23-1.48, p < 0.001, respectively) on multivariable analyses; the addition of HGF improved the predictive accuracies of a standard preoperative model (+ 7%, p < 0.001 and + 8%, p < 0.001, respectively). According to the DCA and MCID, half of the patients had a net benefit by including HGF, but the absolute magnitude remained limited. In pre- and postoperative predictive models, a higher HGF level was significant prognosticator of worse RFS, OS, and CSS; in the preoperative model, the addition of HGF improved accuracies by 6% and 5% for RFS and CSS, respectively. CONCLUSION: Preoperative HGF identified MIBC patients who harbored features of clinically and biologically aggressive disease. Plasma HGF could serve, as part of a panel, as a biomarker to aid in preoperative treatment planning regarding intensity of treatment in patients with clinical MIBC.

A panel of systemic inflammatory response biomarkers for outcome prediction in patients treated with radical cystectomy for urothelial carcinoma.

OBJECTIVES: To determine the predictive and prognostic value of a panel of systemic inflammatory response (SIR) biomarkers relative to established clinicopathological variables in order to improve patient selection and facilitate more efficient delivery of peri-operative systemic therapy. MATERIALS AND METHODS: The preoperative serum levels of a panel of SIR biomarkers, including albumin-globulin ratio, neutrophil-lymphocyte ratio, De Ritis ratio, monocyte-lymphocyte ratio and modified Glasgow prognostic score were assessed in 4199 patients treated with radical cystectomy for clinically non-metastatic urothelial carcinoma of the bladder. Patients were randomly divided into a training and a testing cohort. A machine-learning-based variable selection approach (least absolute shrinkage and selection operator regression) was used for the fitting of several multivariable predictive and prognostic models. The outcomes of interest included prediction of upstaging to carcinoma invading bladder muscle (MIBC), lymph node involvement, pT3/4 disease, cancer-specific survival (CSS) and recurrence-free survival (RFS). The discriminatory ability of each model was either quantified by area under the receiver-operating curves or by the C-index. After validation and calibration of each model, a nomogram was created and decision-curve analysis was used to evaluate the clinical net benefit. RESULTS: For all outcome variables, at least one SIR biomarker was selected by the machine-learning process to be of high discriminative power during the fitting of the models. In the testing cohort, model performance evaluation for preoperative prediction of lymph node metastasis, ≥pT3 disease and upstaging to MIBC showed a 200-fold bootstrap-corrected area under the curve of 67.3%, 73% and 65.8%, respectively. For postoperative prognosis of CSS and RFS, a 200-fold bootstrap corrected C-index of 73.3% and 72.2%, respectively, was found. However, even the most predictive combinations of SIR biomarkers only marginally increased the discriminative ability of the respective model in comparison to established clinicopathological variables. CONCLUSION: While our machine-learning approach for fitting of the models with the highest discriminative ability incorporated several previously validated SIR biomarkers, these failed to improve the discriminative ability of the models to a clinically meaningful degree. While the prognostic and predictive value of such cheap and readily available biomarkers warrants further evaluation in the age of immunotherapy, additional novel biomarkers are still needed to improve risk stratification.
