The Impact of Preoperative Double-J Stent on Perioperative Complications, Recurrence, and Quality of Life in Adult Patients Undergoing Pyeloplasty.

PURPOSE: This study aimed to evaluate the impact of preoperative double-J stent (DJ) in pyeloplasty patients on perioperative complications, recurrence, and quality of life (QoL). METHODS: Pyeloplasties due to ureteropelvic junction obstructions between January 2010 and December 2020 were consecutively identified. A standardized follow-up questionnaire was used. Tabulation was made according to preoperative DJ versus no DJ. Subgroup analyses addressed primary robotic pyeloplasties. RESULTS: Of 95 pyeloplasty patients, 62% received a preoperative DJ. Patients with preoperative DJ exhibited higher rates of Clavien-Dindo (CD) 2 (22 vs. 11%) complications, but not of CD3 (8.5 vs. 8.3%, p = 0.5). After a median follow-up of 61 months, 9 patients exhibited a recurrence, of whom 7 had a preoperative DJ. In QoL assessment, comparable findings were made between patients with and without preoperative DJ. In robotic pyeloplasty patients (n = 73), patients with preoperative DJ (58%, n = 42) experienced higher CD3 complication rates, compared to patients without preoperative DJ (12 vs. 6.5%). Moreover, higher rates of recurrences were observed in preoperative DJ patients (12 vs. 3.2%). CONCLUSION: In a contemporary pyeloplasty cohort, the midterm success rate was good with 91%. Our findings suggest that preoperative DJ is associated with higher recurrence rates. However, QoL did not differ between patients with and without preoperative DJ.

Where Is the Value in Ambulatory Versus Inpatient Surgery?

OBJECTIVE: The aim of this study was to estimate the effect of index surgical care setting on perioperative costs and readmission rates across 4 common elective general surgery procedures. SUMMARY BACKGROUND DATA: Facility fees seem to be a driving force behind rising US healthcare costs, and inpatient-based fees are significantly higher than those associated with ambulatory services. Little is known about factors influencing where patients undergo elective surgery. METHODS: All-payer claims data from the 2014 New York and Florida Healthcare Cost and Utilization Project were used to identify 73,724 individuals undergoing an index hernia repair, primary total or partial thyroidectomy, laparoscopic cholecystectomy, or laparoscopic appendectomy in either the inpatient or ambulatory care setting. Inverse probability of treatment weighting-adjusted gamma generalized linear and logistic regression was employed to compare costs and 30-day readmission between inpatient and ambulatory-based surgery, respectively. RESULTS: Approximately 87% of index surgical cases were performed in the ambulatory setting. Adjusted mean index surgical costs were significantly lower among ambulatory versus inpatient cases for all 4 procedures (P < 0.001 for all). Adjusted odds of experiencing a 30-day readmission after thyroidectomy [odds ratio (OR) 0.70, 95% confidence interval (CI), 0.53-0.93; P = 0.03], hernia repair (OR 0.28, 95% CI, 0.20-0.40; P < 0.001), and laparoscopic cholecystectomy (OR 0.37, 95% CI, 0.32-0.43; P < 0.001) were lower in the ambulatory versus inpatient setting. Readmission rates among ambulatory versus inpatient-based laparoscopic appendectomy were comparable (OR 0.63, 95% CI, 0.31-1.26; P = 0.19). CONCLUSIONS: Ambulatory surgery offers significant costs savings and generally superior 30-day outcomes relative to inpatient-based care for appropriately selected patients across 4 common elective general surgery procedures.

Workplace absenteeism amongst patients undergoing open vs. robotic radical prostatectomy, hysterectomy, and partial colectomy.

BACKGROUND: There is controversy regarding the widespread uptake of robotic surgery across several surgical disciplines. While it has been shown to confer clinical benefits such as decreased blood loss and shorter hospital stays, some argue that the benefits of this technology do not outweigh its high cost. We performed a retrospective insurance-based analysis to investigate how undergoing robotic surgery, compared to open surgery, may impact the time in which an employed individual returns to work after undergoing major surgery. METHODS: We identified a cohort of US adults with employer-sponsored insurance using claims data from the MarketScan database who underwent either open or robotic radical prostatectomy, hysterectomy/myomectomy, and partial colectomy from 2012 to 2016. We performed multiple regression models incorporating propensity scores to assess the effect of robotic vs. open surgery on the number of absent days from work, adjusting for demographic characteristics and baseline absenteeism. RESULTS: In a cohort of 1157 individuals with employer-sponsored insurance, those undergoing open surgery, compared to robotic surgery, had 9.9 more absent workdays for radical prostatectomy (95%CI 5.0 to 14.7, p < 0.001), 25.3 for hysterectomy/myomectomy (95%CI 11.0-39.6, p < 0.001), and 29.8 for partial colectomy (95%CI 14.8-44.8, p < 0.001) CONCLUSION: For the three major procedures studied, robotic surgery was associated with fewer missed days from work compared to open surgery. This information helps payers, patients, and providers better understand some of the indirect benefits of robotic surgery relative to its cost.

The impact of underinsurance on bladder cancer diagnosis, survival, and care delivery for individuals under the age of 65 years.

BACKGROUND: Health insurance is a key mediator of health care disparities. Outcomes in bladder cancer, one of the costliest diseases to treat, may be especially sensitive to a patient's insurance status. METHODS: The Surveillance, Epidemiology, and End Results registry and the National Cancer Data Base were used to identify individuals younger than 65 years who were diagnosed with bladder cancer from 2007 to 2014. The associations between the insurance status (privately insured, insured by Medicaid, or uninsured) and the following outcomes were evaluated: diagnosis with advanced disease, cancer-specific survival, delay in treatment longer than 90 days, treatment in a high-volume hospital, and receipt of neoadjuvant chemotherapy (NAC). RESULTS: Compared with those with private insurance, uninsured and Medicaid-insured individuals were nearly twice as likely to receive a diagnosis of muscle-invasive bladder cancer (odds ratio [OR] for uninsured individuals, 1.90; 95% confidence interval [CI], 1.70-2.12; OR for Medicaid-insured individuals, 2.03; 95% CI, 1.87-2.20). They were also more likely to die of bladder cancer (adjusted hazard ratio [AHR] for uninsured individuals, 1.49; 95% CI, 1.31-1.71; AHR for Medicaid-insured individuals, 1.61; 95% CI, 1.46-1.79). Delays in treatment longer than 90 days were more likely for uninsured (OR, 1.36; 95% CI, 1.12-1.65) and Medicaid-insured individuals (OR, 1.22; 95% CI, 1.03-1.44) in comparison with the privately insured. Uninsured patients had lower odds of treatment at a high-volume facility, and Medicaid-insured patients had lower odds of receiving NAC (P < .001 for both). CONCLUSIONS: Compared with privately insured individuals, uninsured and Medicaid-insured individuals experience worse prognoses and poorer care quality. Expanding high-quality insurance coverage to marginalized populations may help to reduce the burden of this disease.

Facility-Level Variation in Pelvic Lymphadenectomy During Radical Prostatectomy and Effect on Overall Survival in Men with High-Risk Prostate Cancer.

PURPOSE: This study was designed to examine facility-level variation in the extent of pelvic lymphadenectomy and to determine whether more extensive lymphadenectomy is associated with a survival benefit among men with localized high-risk prostate cancer. METHODS: Using data from the National Cancer Data Base, we identified 13,652 men with a high predicted probability of 10-year survival (≤ 65 years of age and Charlson Comorbidity Index score of 0) who underwent radical prostatectomy at 1023 facilities for biopsy-confirmed localized high-risk prostate cancer diagnosed between January 2004 and December 2011. Multilevel, multinomial logistic regression was fitted to predict facility-level probability of receiving different extents of lymphadenectomy. Inverse probability of treatment weighting-adjusted Cox regression model with Bonferroni correction was fitted to compare risk of overall mortality. RESULTS: Overall, 11,284 (82.7%), 1601 (11.7%), and 767 (5.6%) men who underwent radical prostatectomy underwent concomitant none/limited lymphadenectomy (0-9 lymph nodes), standard lymphadenectomy (10-16 lymph nodes), and extended lymphadenectomy (≥ 17 lymph nodes), respectively. Extended lymphadenectomy was not associated with a survival benefit relative to standard lymphadenectomy (hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.48-1.23; p = 0.4) nor no/limited lymphadenectomy (HR 0.77, 95% CI 0.87-2.20; p = 0.29) at a median follow-up of 83.3 months. Risk-adjusted facility-level predicted probabilities of extended, standard, or no/limited lymphadenectomy ranged from 0.01 to 52.6%, 3.3-53.3%, and 17.8-96.3%, respectively. CONCLUSIONS: We found significant facility-level variation in the extent of pelvic lymphadenectomy during radical prostatectomy despite no apparent survival benefit associated with more extensive lymphadenectomy. Further prospective data are needed to reevaluate the role of lymphadenectomy in the management of clinically localized prostate cancer.

Minimally invasive cancer surgery is associated with a lower risk of venous thromboembolic events.

BACKGROUND: Venous thromboembolism (VTE) is a significant source of postoperative morbidity and mortality in patients undergoing common oncologic procedures. We sought to estimate the effect of surgical approach on the risk of developing a VTE. METHODS: IBM Watson Health Marketscan Database was used to conduct this retrospective study. In total, 12 938 patients who underwent either a radical prostatectomy, partial colectomy, or hysterectomy via a minimally invasive or open approach. We used a propensity-weighted logistic regression analysis to assess the independent effect of surgical approach on VTE. The primary outcome of interest was the 90-day rate of VTE after surgery. RESULTS: Patients undergoing minimally invasive surgery across all three surgical procedures were noted to have a lower odds of developing a VTE: (radical prostatectomy, odds ratio [OR]: 0.667, 95% confidence interval [CI]: 0.500-0.891; P = .006 |partial colectomy: OR, 0.620, 95% CI: 0.477-0.805; P < .001| hysterectomy: OR, 0.549 95% CI: 0.353-0.854; P = .008). CONCLUSION: We found that a minimally invasive approach was associated with significantly lower odds of VTE compared with undergoing the same open procedure. This study highlights how surgical approach may be an independent risk factor for development of VTE and may elucidate potential risk mitigation strategy.

Association of surgical approach and prolonged opioid prescriptions in patients undergoing major pelvic cancer procedures.

BACKGROUND: The rise in deaths attributed to opioid drugs has become a major public health problem in the United States and in the world. Minimally invasive surgery (MIS) is associated with a faster postoperative recovery and our aim was to investigate if the use of MIS was associated with lower odds of prolonged opioid prescriptions after major procedures. METHODS: Retrospective study using the IBM Watson Health Marketscan® Commerical Claims and Encounters Database investigating opioid-naïve cancer patients aged 18-64 who underwent open versus MIS radical prostatectomy (RP), partial colectomy (PC) or hysterectomy (HYS) from 2012 to 2017. Propensity weighted logistic regression analyses were used to estimate the independent effect of surgical approach on prolonged opioid prescriptions, defined as prescriptions within 91-180 days of surgery. RESULTS: Overall, 6838 patients underwent RP (MIS 85.5%), 4480 patients underwent PC (MIS 61.6%) and 1620 patients underwent HYS (MIS 41.8%). Approximately 70-80% of all patients had perioperative opioid prescriptions. In the weighted model, patients undergoing MIS were significantly less likely to have prolonged opioid prescriptions in all three surgery types (Odds Ratio [OR] 0.737, 95% Confidence Interval [CI] 0.595-0.914, p = 0.006; OR 0.728, 95% CI 0.600-0.882, p = 0.001; OR 0.655, 95% CI 0.466-0.920, p = 0.015, respectively). CONCLUSION: The use of the MIS was associated with lower odds of prolonged opioid prescription in all procedures examined. While additional studies such as clinical trials are needed for further confirmation, our findings need to be considered for patient counseling as postoperative differences between approaches do exist.

Impact of adjuvant chemotherapy in patients with adverse features and variant histology at radical cystectomy for muscle-invasive carcinoma of the bladder: Does histologic subtype matter?

BACKGROUND: The use of adjuvant chemotherapy (AC) in pure urothelial carcinoma of the bladder is established. Regarding variant histology, there is a gap in knowledge concerning the optimal treatment after radical cystectomy (RC). The objective of this study was to assess the effect of AC on overall survival (OS) in patients who had pure urothelial carcinoma, urothelial carcinoma with concomitant variant histology, or another pure variant histology. METHODS: Within the National Cancer Data Base, 15,397 patients who underwent RC for nonmetastatic, localized carcinoma of the bladder and had positive lymph nodes (T2N+) or locally advanced stage (≥T3N0/N+) were identified, excluding those who had previously received neoadjuvant chemotherapy. Multivariable Cox regression models were used to examine the specific effect of AC on OS stratified by each distinct histologic subtype, including pure urothelial carcinoma, micropapillary or sarcomatoid differentiation, squamous cell carcinoma, adenocarcinoma, and neuroendocrine tumors. To account for immortal time bias, Cox regression analyses and Kaplan-Meier analyses were conducted with a landmark at 3 months. RESULTS: In multivariable landmark analyses, AC compared with initial observation was associated with an OS benefit for patients who had pure urothelial carcinoma (hazard ratio, 0.87; 95% confidence interval, 0.82-0.91), whereas no differences were observed with regard to those who had variant histology. CONCLUSIONS: Multivariable Cox regression landmark analysis revealed a survival benefit from AC for patients with a pure urothelial carcinoma. However, a survival benefit of AC for patients who had urothelial carcinoma with concomitant variant histology or other pure variant histology was not demonstrated.

Quality of Care in the Treatment of Localized Intermediate and High Risk Prostate Cancer at Minority Serving Hospitals.

PURPOSE: We investigated the quality of care at minority serving hospitals compared to other institutions for men with localized intermediate and high risk prostate cancer. MATERIALS AND METHODS: Using the National Cancer Database we identified 536,539 men 40 years old or older who presented with localized intermediate and high risk prostate cancer in the United States between 2004 and 2015. Institutions were ranked according to the proportion of black and Hispanic patients treated at a given institution, and the top decile institutions were defined as minority serving hospitals. We used multivariable analyses to characterize the association between minority serving hospitals and 3 end points, including receipt of definitive treatment, time to definitive treatment and receipt of androgen deprivation therapy in young (65 years or younger) and healthy (no comorbidity) men treated with external beam radiation therapy. RESULTS: A total of 162 and 1,168 hospitals were defined as minority and nonminority serving hospitals, respectively. On multivariable analyses treatment at minority serving hospitals was associated with decreased odds of receiving definitive treatment (adjusted OR 0.73, 95% CI 0.62-0.85, p <0.001). Adjusted mean ± SE time to treatment was significantly longer at minority serving hospitals compared to nonminority serving hospitals (4.9 ± 2.2 days, p = 0.024). Among young and healthy men there was no association between treatment at a minority serving hospital and receipt of androgen deprivation therapy in conjunction with external beam radiation (AOR 0.90, 95% CI 0.75-1.09, p = 0.291). CONCLUSIONS: Treatment at a minority serving hospital was associated with lower odds of receiving definitive therapy and longer time to definitive therapy for localized intermediate and high risk prostate cancer despite adjustment for race. This suggests that some racial disparities in prostate cancer may be explained by the sites at which racial and/or ethnic minorities receive care.

Comparing the Association Between Insurance and Mortality in Ovarian, Pancreatic, Lung, Colorectal, Prostate, and Breast Cancers.

BACKGROUND: Insurance coverage is associated with better cancer outcomes; however, the relative importance of insurance coverage may differ between cancers. This study compared the association between insurance coverage at diagnosis and cancer-specific mortality (CSM; insurance sensitivity) in 6 cancers. PATIENTS AND METHODS: Using the SEER cancer registry, data were abstracted for individuals diagnosed with ovarian, pancreatic, lung, colorectal, prostate, or breast cancer in 2007 through 2010. The association between insurance coverage at diagnosis and CSM was modeled using a Fine and Gray competing-risks regression adjusted for demographics. An interaction term combining insurance status and cancer type was used to test whether insurance sensitivity differed between cancers. Separate models were fit for each cancer. To control for lead-time bias and to assess whether insurance sensitivity may be mediated by earlier diagnosis and treatment, additional models were fit adjusting for disease stage and treatment. RESULTS: Lack of insurance was associated with an increased hazard of CSM in all cancers (P<.01). The magnitude of the effect differed significantly between cancers (Pinteraction=.04), ranging from an adjusted hazard ratio of 1.13 (95% CI, 1.01-1.28) in ovarian and 1.19 (95% CI, 1.11-1.29) in pancreatic cancer to 2.19 (95% CI, 2.02-2.37) in breast and 2.98 (95% CI, 2.54-3.49) in prostate cancer. The benefit of insurance was attenuated after adjusting for stage and treatment (eg, screening/early treatment effect), with the largest reductions in prostate, breast, and colorectal cancers. CONCLUSIONS: Greater insurance sensitivity was seen in screening-detected malignancies with effective treatments for early-stage disease (eg, prostate, breast, and colorectal cancers). Given that this differential is significantly reduced after adjusting for stage and treatment, our results suggest that a significant portion (but not all) of the benefit of insurance coverage is due to detection and treatment of certain curable early-stage cancers.

Characterizing trends in treatment modalities for localized muscle-invasive bladder cancer in the pre-immunotherapy era.

INTRODUCTION: Muscle-invasive bladder cancer (MIBC) is an aggressive disease for which treatment strategies are continuously evolving. We characterized trends in treatment modalities for MIBC from 2004 to 2013 (the "pre-immunotherapy era") and identified predictors of receiving the current standard of care treatment: neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC). METHODS: We used the National Cancer Database to identify individuals diagnosed with clinically localized MIBC from 2004 to 2013. We calculated the yearly prevalence of NAC followed by RC, RC as first treatment, trimodal therapy, chemotherapy and/or radiation alone, and no treatment. We then identified factors associated with receiving NAC prior to RC. RESULTS: There was a notable increase in the use of NAC followed by RC over the study period, from 3.68% in 2004 to 14.83% in 2013 (P < 0.001). Factors associated with decreased odds of receiving this regimen included being older, Black, uninsured, less educated, and more burdened by comorbidities. Rates of trimodal therapy and chemotherapy and/or radiation alone remained relatively constant (approximately 5 and 17%, respectively). There was a consistent decline in the proportion of patients who did not receive any treatment, down to 34.20% in 2013. CONCLUSION: Trends in localized MIBC treatment have evolved substantially since the early 2000s, and certain patient characteristics are associated with lower odds of receiving the current standard of care. This serves as a foundation from which to judge the impact of the upcoming immunotherapy era on the treatment landscape for this disease.

An external validation of the nocera nomogram: Predicting non-organ confined stage of ≥pT3 in cT1 clear cell renal cell carcinoma.

Background: Only one previously published study by Nocera et al. addressed the risk of upstaging to ≥pT3 in cT1 clear cell renal cell carcinoma (ccRCC) by using characteristics of the R.E.N.A.L and PADUA score (age, tumor size, rim location, exophytic rate, polar involvement) developing an accurate nomogram. However, this nomogram has never been externally validated yet. Material and methods: The study cohort consisted of 288 patients with cT1a-b ccRCC, diagnosed between 2008-2021 at the University Hospital Frankfurt, Germany. Analyses addressed clinical, tumor and radiographic characteristics. The external validation of the nomogram relied on accuracy calculations derived from the area under the curve of the receiver operator characteristic analysis. Results: Overall, 11.8% (n=34) patients harbored ≥pT3 ccRCC. Median radiographic tumor size (3.6 vs. 5.3cm), R.E.N.A.L. (8 vs. 9 points) and PADUA score (9 vs. 11 points), as well as proportions of renal sinus involvement (82.4% vs. 51.6%), renal hilus involvement (44.1 vs. 13.0%), and medial rim location significantly differed between the pT1-2 and ≥pT3 group (all p ≤ 0.01). In subgroup analyses of small renal mass ccRCC patients (<4cm, cT1a), only 3.8% (n=6) patients had ≥pT3 pathology. Upstaged patients were significantly older and more frequently had endophytic tumor than pT1-2 counterparts (p<0.05). The external validation of the Nocera nomogram showed a good accuracy of 76.6%. Using the suggested cut-off of 21%, 26.5% of patients exhibited ≥pT3 ccRCC. Conversely, within patients below cut-off, 5.9% patients exhibited ≥pT3 ccRCC. Conclusion: We reported the first external validation of the nomogram addressing the risk of ≥pT3 in cT1 ccRCC patients, demonstrating a good accuracy, with a low false-negative rate. Therefore, the nomogram can accurately be used for patients' counselling and treatment decision making.

Sex-specific Differences in the Quality of Treatment of Muscle-invasive Bladder Cancer Do Not Explain the Overall Survival Discrepancy.

BACKGROUND: While bladder cancer is less common among women, female sex is associated with worse oncological outcomes. OBJECTIVE: To evaluate sex-specific differences in initial presentation and treatment patterns of muscle-invasive bladder cancer. DESIGN, SETTING, AND PARTICIPANTS: A retrospective study using the National Cancer Database to identify individuals diagnosed with muscle-invasive bladder cancer (cT2-T4aN0M0) between 2004 and 2013. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable logistic regression and negative binomial regression with Bonferroni correction were used to investigate seven treatment measures: care at a high-volume facility, receipt of definitive therapy, delayed treatment, receipt of neoadjuvant or adjuvant chemotherapy, receipt of pelvic lymph node dissection, and number of lymph nodes removed. The secondary outcome was overall survival. RESULTS AND LIMITATIONS: We identified 27525 patients, 27.4% of whom were females. Females were diagnosed significantly more often with nonurothelial carcinoma (15.1% vs 9.9%, p<0.001), with squamous carcinoma being the most prevalent variant (46.9%). After Bonferroni correction, there was no difference in six out of seven treatment quality measures. Females were significantly less likely to experience delayed treatment (odds ratio 0.89, 95% confidence interval [CI] 0.84-0.93, p<0.001). Females had significantly worse overall survival compared with males (hazard ratio 1.04, 95% CI 1.00-1.07, p=0.030). Limitations arise from the retrospective design of the study. CONCLUSIONS: Despite little difference in treatment quality measures, female sex is associated with worse overall survival among individuals with muscle-invasive bladder cancer. Our findings suggest that differences in treatment patterns are unlikely to explain the differences in overall survival. Future initiatives should focus on root causes for gender-specific differences in pathological staging and features at diagnosis. PATIENT SUMMARY: In this study, we did not find differences in the treatment of bladder cancer between men and women that could readily explain why women diagnosed with this disease are more likely to die.

Contemporary Treatment Patterns for Non-muscle-invasive Bladder Cancer: Has the Use of Radical Cystectomy Changed in the BCG Shortage Era?

OBJECTIVE: To examine recent treatment trends for non-muscle-invasive bladder cancer (NMIBC), and specifically, to assess whether there was a change in use radical cystectomy (RC) between 2008 and 2015 using data from the Surveillance, Epidemiology, and End Results database. METHODS: We identified patients presenting with high-grade T1 (T1HG) NMIBC at diagnosis during the study period. Treatment was dichotomized into "RC" and "local treatment" (which included transurethral resection and intravesical therapies). We then employed multivariable logistic regression models to assess the odds of undergoing RC across the study period. Additionally we examined the rates of RC for T1HG NMIBC during the period of BCG-shortage, defined as 2012-2015. RESULTS: We identified 21,817 individuals diagnosed with T1HG bladder cancer during the study period. The majority of patients underwent local treatment (94.5%). During the shortage period, the rate of RC for T1HG NMIBC was significantly lower compared to the preshortage era (5.1% vs 5.9%, P = .007). Across the study period, the utilization of RC for T1HG NMIBC decreased significantly (odds ratio 0.99 per quarter, 95% confidence interval 0.98-0.99, P = .017). CONCLUSION: In our cohort of patients diagnosed with T1HG bladder cancer, we found a significant decrease in the use of radical cystectomy across the study period. Contrary to the hypothesis of increasing rates of RC in the face of BCG shortage, the rate of RC was significantly higher in the pre-shortage era. Further examination of NMIBC treatment patterns will be necessary to assess the impact of BCG availability on therapeutic pathways and oncologic outcomes in patients with high-grade NMIBC.

Recovery from minimally invasive vs. open surgery in kidney cancer patients: Opioid use and workplace absenteeism.

PURPOSE: Does surgical approach (minimally invasive vs. open) and type (radical vs. partial nephrectomy) affects opioid use and workplace absenteeism. MATERIALS AND METHODS: Retrospective multivariable regression analysis of 2,646 opioid-naïve patients between 18 and 64 undergoing radical or partial nephrectomy via either a minimally invasive vs. open approach for kidney cancer in the United States between 2012 and 2017 drawn from the IBM Watson Health Database was performed. Outcomes included: (1) opioid use in opioid-naïve patients as measured by opioid prescriptions in the post-operative setting at early, intermediate and prolonged time periods and (2) workplace absenteeism after surgery. RESULTS: Patients undergoing minimally invasive surgery had a lower odds of opioid use in the early and intermediate post-operative periods (early: odds ratio [OR], 0.77; 95% confidence interval [CI], 0.62-0.97; p=0.02, intermediate: OR, 0.60; 95% CI, 0.48-0.75; p<0.01), but not in the prolonged setting (prolonged: OR, 1.00; 95% CI, 0.75-1.34; p=0.98) and had earlier return to work (minimally invasive vs. open: -10.53 days; 95% CI, -17.79 to -3.26; p<0.01). Controlling for approach, patient undergoing partial nephrectomy had lower rates of opioid use across all time periods examined and returned to work earlier than patients undergoing radical nephrectomy (partial vs. radical: -14.41 days; 95% CI, -21.22 to -7.60; p<0.01). CONCLUSIONS: Patients undergoing various forms of surgery for kidney cancer had lower rates of peri-operative opioid use, fewer days of workplace absenteeism, but no difference in long-term rates of opioid use in patients undergoing minimally invasive as compared to open surgery.

Radical Cystectomy vs. Multimodality Treatment in T2N0M0 Bladder Cancer: A Population-based, Age-matched Analysis.

BACKGROUND: Controversy still exists regarding efficacy of multimodality treatment (MMT) vs. radical cystectomy (RC) for urothelial carcinoma of the urinary bladder (UCUB). METHODS: Within the SEER database (2004-2016), we retrospectively identified patients with stage T2N0M0 UCUB. Competing risks regression (CRR) tested cancer-specific mortality (CSM) and adjusted for other-cause mortality after MMT vs. RC. Exact matching for age was applied. Subgroup analyses focused on differences in chemotherapy or lymph node dissection rates. In sensitivity analyses, we accounted for 40% understaging rate in patients who underwent MMT. RESULTS: Of 9862 patients with T2N0M0 UCUB, 2675 (27.1%) underwent MMT vs. 5751 (58.3%) RC vs. 1436 (14.6%) radiotherapy (RT) without chemotherapy. MMT rate increased (annually +3.0%, P < .01) and MMT patient age was significantly higher (median 77 years) than RC patient age (68 years). In exact age-matched analyses, 10-year CSM rates were 44.3% vs. 25.9% for MMT vs. RC (multivariate hazard ratio [HR] 0.48); 44.1% vs. 22.8% for MMT vs. RC with chemotherapy (HR 0.43); 40.5% vs. 31.1% for MMT vs. RC without lymph node dissection (HR 0.66), and 55.6% vs. 27.3% for RT without chemotherapy vs. RC (HR 0.37, all P < .001). Sensitivity analyses that addressed understaging of patients who underwent MMT resulted in virtually the same CSM rates. CONCLUSION: In patents with T2N0M0, MMT or even more so RT alone may be associated with higher CSM than RC, even in exact age-matched multivariate CRR analyses, which adjust for other-cause mortality. In consequence, patients with T2 UCUB should be informed of this possible CSM disadvantage outside of highly specialized centers.

Performance and Impact of Prostate Specific Membrane Antigen-Based Diagnostics in the Management of Men with Biochemical Recurrence of Prostate Cancer and its Role in Salvage Lymph Node Dissection.

Up to 50% of patients initially treated for prostate cancer in a curative intent experience biochemical recurrence, possibly requiring adjuvant treatment. However, salvage treatment decisions, such as lymph node dissection or radiation therapy, are typically based on prostate specific antigen (PSA) recurrence. Importantly, common imaging modalities (e.g., computed tomography [CT], magnetic resonance imaging, and bone scan) are limited and the detection of recurrent disease is particularly challenging if PSA is low. Prostate specific membrane antigen (PSMA) positron-emission tomography/computed tomography (PET/CT) is a novel and promising imaging modality which aims to overcome the incapability of early identification of distant and regional metastases. Within this review, we summarize the current evidence related to PSMA-PET/CT in prostate cancer men diagnosed with biochemical recurrence after local treatment with curative intent. We discuss detection rates of PSMA-PET/CT stratified by PSA-levels and its impact on clinical decision making. Furthermore, we compare different image-fusion techniques such as PSMA-PET vs. F-/C-Choline-PET scans vs. PSMA-single photon emission computed tomography/CT. Finally, we touch upon the contemporary role of radio-guided-PSMA salvage lymphadenectomy.

Care Setting as a Modifiable Predictor of Perioperative Cost and Outcomes following Elective Urinary Stone Surgery.

INTRODUCTION: We sought to identify predictors of index surgical care setting and to determine if care setting influences risk adjusted perioperative costs and/or 30-day revisits following elective surgery for urinary stones. METHODS: Using 2014 HCUP (Healthcare Cost and Utilization Project) all payer claims data from New York and Florida, we retrospectively identified 29,433 patients undergoing index ureteroscopy or shock wave lithotripsy. We used inverse probability of treatment weighting adjusted multivariable logistic and gamma regression to assess the association between index surgical care setting and 30-day revisits and total costs, respectively. RESULTS: Most urinary stone procedures (70.8%) were performed in the ambulatory setting. Underinsurance was associated with lower odds of undergoing surgery in the ambulatory setting (Medicaid vs private: OR 0.44, 95% CI 0.37-0.53; p <0.001; self-pay vs private: OR 0.21, 95% CI 0.17-0.26; p <0.001). Adjusted mean index surgical and 30-day acute care costs were significantly lower among ambulatory vs inpatient/emergency department cases ($4,746.10 vs $10,669.26 and $5,434.42 vs $11,729.39, both p <0.001), respectively. Ambulatory surgery was independently associated with lower odds of experiencing a 30-day revisit (OR 0.82, 95% CI 0.72-0.94; p=0.005). CONCLUSIONS: Urinary stone cases managed surgically in an ambulatory setting had lower risk adjusted costs and odds of a 30-day revisit compared to those managed in an inpatient setting. Our findings support use of ambulatory rather than inpatient based elective surgery for uncomplicated urinary stones. We invite clinicians and policymakers alike to reconsider clinical and nonclinical factors that influence pathways of care.

Is Standardization Transferable? Initial Experience of Urethral Surgery at the University Hospital Frankfurt.

Background: Since January 2018 performance of urethroplasties is done on regular basis at the University Hospital Frankfurt (UKF). We aimed to implement and transfer an institutional standardized perioperative algorithm for urethral surgery (established at the University Hospital Hamburg-Eppendorf-UKE) using a validated Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROM) in patients undergoing urethroplasty at UKF. Materials and Methods: We retrospectively analyzed all patients who underwent urethroplasty for urethral stricture disease between January 2018 and January 2020 at UKF. All patients were offered to revisit for clinical follow-up (FU) and completion of USS-PROM. Primary end point was stricture recurrence-free survival (RFS). Secondary endpoints were functional outcomes, quality of life (QoL), and patient satisfaction. Results: In total, 50 patients underwent urethroplasty and 74 and 24% had a history of previous urethrotomy or urethroplasty, respectively. A buccal mucosal graft urethroplasty was performed in 86% (n = 43). After patient's exclusion due to lost of FU, FU <3 months, and/or a pending second stage procedure, 40 patients were eligible for final analysis. At median FU of 10 months (interquartile-range 5.0-18.0), RFS was 83%. After successful voiding trial, the postoperative median Qmax significantly improved (24.0 vs. 7.0 mL/s; p < 0.01). Conversely, median residual urine decreased significantly (78 vs. 10 mL; p < 0.01). Overall, 95% of patients stated that QoL improved and 90% were satisfied by the surgical outcome. Conclusions: We demonstrated a successful implementation and transfer of an institutional standardized perioperative algorithm for urethral surgery from one location (UKE) to another (UKF). In our short-term FU, urethroplasty showed excellent RFS, low complication rates, good functional results, improvement of QoL and high patient satisfaction. PROMs allow an objective comparison between different centers.
