RESUMO

OBJECTIVE: To investigate impact of body mass index (BMI) on survival across different histologies and stages of renal cell carcinoma (RCC). METHODS: We conducted a retrospective multicenter analysis of clear cell (ccRCC) and non-ccRCC. Obesity was defined according to the WHO criteria (non-Asian BMI >30 Kg/m2, Asian BMI >27.5 Kg/m2). Multivariable analysis (MVA) via Cox regression model was conducted for all-cause (ACM), cancer-specific mortality (CSM) and recurrence. RESULTS: A total of 3,880 patients with a median follow-up of 31 (IQR 9-64) months were analyzed. Overall, 1,373 (35.3%) were obese; 2,895 (74.6%) were ccRCC and 985 (25.3%) were non-ccRCC (chRCC 246 [24.9%], pRCC 469 [47.6%] and vhRCC 270 [27.4%]). MVA in ccRCC revealed obesity associated with decreased risk of ACM, CSM and recurrence (hazard ratio [HR] 0.80, P = 0.044; HR 0.71, P = 0.039; HR 0.73, P = 0.012, respectively), while in non-ccRCC was not associated with decreased risk of ACM, CSM, and recurrence (P = 0.84, P = 0.53, P = 0.84, respectively). Subset analysis in stage IV ccRCC demonstrated obesity as associated with a decreased risk of ACM, CSM, and recurrence (HR 0.68, P = 0.04; HR 0.59, P = 0.01; HR 0.59, P = 0.01, respectively), while in stage I-III ccRCC was not (P = 0.21; P = 0.30; P = 0.19, respectively). CONCLUSION: Our findings refute a broad "obesity paradox" for RCC. Obesity was not associated with improved survival in non-ccRCC and in nonmetastatic ccRCC, while metastatic ccRCC patients with obesity had improved survival outcomes.

RESUMO

PURPOSE: American Urological Association guidelines recommend testicular prosthesis discussion prior to orchiectomy. Utilization may be low. We compared outcomes and care utilization between concurrent implant (CI) and staged implant (SI) insertion after radical orchiectomy. MATERIALS & METHODS: The MarketScan Commercial claims database (2008-2017) was queried for men ages >18 years who underwent radical orchiectomy for testicular mass, stratified as orchiectomy with no implant, CI, or SI. 90-day outcomes included rate of reoperation, readmission, emergency department (ED) presentation, and outpatient visits. Regression models provided rate ratio comparison. RESULTS: 8803 patients (8564 no implant, 190 CI, 49 SI; 2.7% implant rate) were identified with no difference in age, Charlson Comorbidity Index, insurance plan, additional cancer treatment, or metastasis. Median perioperative cost at orchiectomy (+/- implant) for no implant, CI, and SI were $5682 (3648-8554), $7823 (5403-10973), and $5380 (4130-10521), respectively (p<0.001). Median perioperative cost for SI at implantation was $8180 (4920-14591) for a total cost (orchiectomy + implant) of $13650 (5380 + 8180). CI patients were more likely to have follow-up (p = 0.006) with more visits (p = 0.030) compared to the SI group post-implantation but had similar follow-up (p = 0.065) and less visits (p = 0.025) compared to the SI patients' post-orchiectomy period. Overall explant rates were 4.7% for CI and 14.3% for SI (p = 0.04) with a median time to explant of 166 (IQR: 135-210) and 40 days (IQR: 9.5-141.5; p = 0.06). Median cost of removal was $2060 (IQR: 967-2880). CONCLUSIONS: CI placement has less total perioperative cost, lower explant rate, and similar postoperative utilization to SI.

RESUMO

BACKGROUND: The Surgery in Early Metastatic Seminoma (SEMS) trial examined retroperitoneal lymph node dissection as first-line treatment for patients with isolated 1-3 cm retroperitoneal lymphadenopathy. To date, the standard of care for these patients has been either chemotherapy or radiotherapy. Herein, we evaluated the relative cost-effectiveness of these management strategies. METHODS: A microsimulation model assessed the cost-effectiveness of retroperitoneal lymph node dissection, chemotherapy, and radiotherapy for stage IIA seminoma. Sensitivity analyses were performed to evaluate model robustness. Retroperitoneal lymph node dissection recurrence probabilities were obtained from the SEMS trial. All other probability and utility values were obtained from published literature. Primary outcomes included costs from a commercial insurer's perspective, effectiveness (quality adjusted life-years [QALYs]), and incremental cost-effectiveness ratios using a willingness-to-pay threshold of $100 000/QALY. RESULTS: At a lifetime horizon, the mean costs per patient for retroperitoneal lymph node dissection, radiotherapy, and chemotherapy were $58 469, $98 783, and $104 096, and the mean QALYs were 40.61, 40.70, and 39.15, respectively. Retroperitoneal lymph node dissection was found to be the most cost-effective approach because of high costs and accrued disutility of chronic toxicities associated with radiotherapy (cost-effectiveness ratios = $433 845/QALY) and chemotherapy (dominated). On 1-way sensitivity analyses, retroperitoneal lymph node dissection was no longer cost-effective if the probabilities of infertility and cardiovascular toxicity after radiotherapy were less than 13% and 16%, respectively, or if the 2-year probability of progression after retroperitoneal lymph node dissection was more than 26%. CONCLUSIONS: Retroperitoneal lymph node dissection was the most cost-effective treatment approach for stage IIA seminoma. These findings support clinical guideline consideration of including retroperitoneal lymph node dissection as a treatment option for well-selected patients with stage IIA seminoma.

RESUMO

INTRODUCTION: We sought to determine whether loss of renal function increases risk of recurrence and metastases in renal cell carcinoma (RCC), and whether this impact was age-related. MATERIALS AND METHODS: We performed a retrospective analysis of the International Marker Consortium for Renal Cancer (INMARC) registry. Patients were separated into younger (<65 years old) and elder (≥65 years old) age groups, and rates of de novo estimated glomerular filtration rate (eGFR<45 mL/min/1.73m2 [eGFR<45]) were calculated. Multivariable analysis (MVA) was conducted for predictors of progression-free survival (PFS) and all-cause mortality (ACM). Kaplan-Meier Analysis (KMA) was conducted for PFS and overall survival (OS) in younger and elder age groups stratified by functional status. RESULTS: We analyzed 1805 patients (1113 age<65, 692 age≥65). On MVA in patients <65, de novo eGFR<45 was independently associated with greater risk for worsened progression (HR=1.61, P=.038) and ACM (HR=1.82, P=.018). For patients ≥65, de novo eGFR<45 was not independently associated with progression (P=.736), or ACM (P=.286). Comparing patients with de novo eGFR<45 vs. eGFR ≥45, KMA demonstrated worsened 5-year PFS and OS in patients <65 (PFS: 68% vs. 86%, P<.001; OS: 73% vs. 90%, P<.001), while in patients ≥65, only 5-year OS was worsened (77% vs. 81%, P<.021). CONCLUSION: Development of de novo eGFR<45 was associated with more profound impact on patients <65 compared to patients ≥65, being an independent risk factor for PFS and ACM. The mechanisms of this phenomenon are unclear but underscore desirability for nephron preservation when safe and feasible in younger patients.

RESUMO

OBJECTIVES: To evaluate effects of worsening surgically induced chronic kidney disease (CKD-S) on oncological and non-oncological survival outcomes in renal cell carcinoma (RCC). PATIENTS AND METHODS: We performed a retrospective analysis of patients who underwent partial (PN) or radical nephrectomy (RN) and were free of preoperative CKD (estimated glomerular filtration rate [eGFR] ≥60 mL/min/1.73 m2 ). Patients were stratified by CKD stage at last follow-up: no CKD-S (eGFR ≥60 mL/min/1.73 m2 ), de novo CKD-S 3a (eGFR 45-59 mL/min/1.73 m2 ), CKD-S 3b (eGFR <45 and ≥30 mL/min/1.73 m2 ) and CKD-S 4 (eGFR <30 and ≥15 mL/min/1.73 m2 ). The primary outcome was all-cause mortality (ACM). Secondary outcomes included non-cancer mortality (NCM), cancer-specific mortality (CSM) and de novo CKD-S Stage 3/4. Multivariable analysis (MVA) was utilised to identify risk factors for outcomes. Kaplan-Meier analysis (KMA) was utilised to evaluate overall (OS), non-cancer (NCS), and cancer-specific survival with respect to CKD-S categories. RESULTS: We analysed 3239 patients. The mean preoperative and last-follow-up eGFRs were 87.4 and 69.5 mL/min/1.73 m2 , respectively. On last follow-up, 57.9% (n = 1876) had no CKD-S, 18.7% (n = 606) had CKD-S 3a, 15.1% (n = 489) had CKD-S 3b and 8.3% (n = 268) had CKD-S 4. On MVA, de novo CKD-S 3b and 4 were independently associated with ACM (hazard ratios [HRs] 1.3-2.1, P = 0.003-0.001) and NCM (HRs 1.5-2.8, P = 0.021-0.001), but not CSM (P = 0.219-0.909); de novo CKD-S 3a was not predictive for any mortality outcomes (P = 0.102-0.81). RN was independently associated with CKD-S 3-4 (HRs 1.78-1.99, P < 0.001-0.035). Comparing no CKD-S, CKD-S 3a, CKD-S 3b and CKD-S 4, KMA demonstrated worsening outcomes with progressive CKD-S stage: 5-year OS 84% vs 78% vs 71% vs 60% (P < 0.001) and 5-year NCS 93% vs 87% vs 83% vs 72% (P < 0.001). CONCLUSION: Development of CKD-S Stage 3b and 4, but not 3a, was associated with worsened ACM and NCM. The decision to proceed with nephron preservation via PN should be individualised based on oncological risk and risk of functional decline to CKD-S 3b or 4, and not CKD-S 3a.

RESUMO

Background: Several markers of inflammation have been associated with oncologic outcomes. Prognostic markers are not well-defined for renal cell carcinoma (RCC). We sought to investigate the association of preoperative neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and De Ritis ratio with mortality in RCC. Methods: Multi-center retrospective analysis of patients undergoing surgery for RCC. Primary outcome of interest was all-cause mortality (ACM). Secondary outcomes were non-cancer mortality (NCM) and cancer-specific mortality (CSM). Elevated NLR was defined as ≥2.27, elevated PLR as ≥165, and elevated De Ritis ratio as ≥ 2.72. Multivariable cox regression analysis (MVA) was conducted to elucidate risk factors for primary and secondary outcomes, and Kaplan-Meier analysis (KMA) was used to evaluate survival outcomes comparing elevated and non-elevated NLR, PLR, and De Ritis ratio. Results: 2656 patients were analyzed (874 patients had elevated NLR; 480 patients had elevated PLR and 932 patients had elevated De Ritis). Elevated NLR was a significant predictor of ACM (HR 1.32, 95% CI: 1.07-1.64, p=0.003) and NCM (HR 1.79, 95% CI: 1.30-2.46, p<0.001) in MVA. Elevated De Ritis was a significant predictor of ACM (HR 2.04, 95% CI: 1.65-2.52), NCM (HR 1.84, 95% CI: 1.33-2.55, p<0.001), and CSM (HR 1.97, 95% CI:1.48-2.63, p<0.001). KMA revealed significant difference in 5-year overall survival (OS) (48% vs. 68%, p<0.001), non-cancer survival (NCS) (69% vs. 87%, p<0.001), and cancer-specific survival (CSS) (60% vs. 73%, p<0.001) for elevated versus non-elevated NLR. For PLR, there was a difference in 5-year OS (51% vs. 61%, p<0.001) and CSS (60% vs. 73%, p<0.001) with KMA. Conclusions: Elevated NLR was independently associated with worse ACM and NCM, while elevated De Ritis was predictive for CSM in addition to ACM and NCM. These differences may be useful in refining risk stratification with respect to cancer-related and non-cancer mortality in RCC patients and deserve further investigation.

RESUMO

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.

RESUMO

OBJECTIVE: To determine the impact of health care system access on outcomes for Hispanic and Non-Hispanic White patients with renal cell carcinoma (RCC). METHODS: We retrospectively analyzed Hispanic and non-Hispanic White patients diagnosed with localized RCC between 2007 and 2020. We used Health Resources and Services Administration criteria to identify patients living in Medically Underserved Areas (MUA). Primary outcome all-cause mortality and cancer-specific survival using Log Rank test on Kaplan Meier Analysis. Secondary outcome was all-cause mortality and cancer specific survival on Cox Regression when adjusting for risk factors. RESULTS: We analyzed 774 patients, 246 (31.8%) Hispanic patients and 528 (68.2%) Non-Hispanic White patients. Hispanic ethnicity was associated with lower risk of ACM (HR 0.53, P = 0.019) and there was no difference for cancer specific survival (HR 0.57, P = 0.059). Living in a MUA was associated with worse all-cause mortality (P = 0.010) but not cancer specific survival (CSS) (P = 0.169). Comparing Hispanic and Non-Hispanic Whites, KMA revealed no difference in 5-year all-cause mortality (83.1% vs. 78.8%, P = 0.254) and 5-year CSS (85.7% vs. 85.4%, P = 0.403). CONCLUSIONS: Hispanics had lower all-cause mortality risk and no significant differences in 5-year overall survival and CSS compared to non-Hispanic Whites. Our findings indicate that tertiary referral centers may help mitigate inequalities in access to care.

RESUMO

Over the last decade, an increasing number of immune checkpoint inhibitors (ICIs) have been assessed for therapeutic efficacy in urothelial carcinoma (UC). The high cost has prompted multiple cost-effectiveness analyses for the various disease stages, with no established consensus. We reviewed the literature to assess the available cost-effectiveness studies and summarize their findings. Studies were filtered for a calculated incremental cost-effectiveness ratio (ICER) to standardize comparison. Over 2600 articles were narrowed to eight primary investigations: one for BCG-refractory non-muscle invasive (NMI), one for neoadjuvant therapy in muscle-invasive (MI), and six for advanced disease. Cost-effectiveness was not achieved for NMI disease. Atezolizumab met the willingness-to-pay (WTP) threshold as neoadjuvant therapy for MI disease compared to chemotherapy, but with multiple limitations on the interpretation. Of the six studies on advanced disease, the results were mixed. This was at least partially attributable to varied methodologies including extrapolated time horizons, inconsistent cost inputs, and different WTP thresholds. Overall, the aggregate results were not compelling enough to establish ICIs as cost-effective compared to conventional chemotherapy. Value may improve with continued investigation into long-term outcomes, refined patient selection, and pricing discounts.

RESUMO

OBJECTIVE: To evaluate the potential impact of alterations in 'patient' position on laser-induced ureteric stone retropulsion in an in vitro model. MATERIALS AND METHODS: A ceramic (phantom) stone was placed in a water-filled clear polymer tube and subjected to continuous laser energy until the stone had retropulsed a distance of 10 cm. The trial was stopped after 60 s if the stone had not reached 10 cm. The time and total energy needed to cause 10 cm of retropulsion were recorded at incline angles of 0°, 10°, 20°, and 40°; 10 trials at each angle were completed. The study was then repeated with pure calcium phosphate brushite stones. RESULTS: Retropulsion decreased with increasing incline angle of the saline-filled clear polymer tube. At 0° of incline the phantom stone reached a distance of 10 cm after 7.4 s. At 10°, 20° and 40°, the phantom stone migrated a mean maximum distance of 3.1, 1.2 and 0.7 cm, respectively, and the trial was stopped after 60 s. For the calcium phosphate stone, at 0° and 10° of incline, the stone reached 10 cm after 6.9 and 42.8 s, respectively (P < 0.05). At 20° and 40°, the calcium phosphate stone moved a mean maximum distance of 2.4 and 1 cm, and the trial was stopped after 60 s. CONCLUSION: Alterations in the angle of inclination reduced stone retropulsion during ureteroscopic lithotripsy in an in vitro model to <1 cm. Increasing the incline angle of a patient may effectively preclude retropulsion when performing laser lithotripsy of ureteric stones.

RESUMO

Depression and sleep problems are highly prevalent disorders that are often comorbid with other medical disorders. We evaluated the prevalence and associations of these conditions in patients presenting to a Men's Health clinic. In this retrospective study, 124 patients presenting to a Men's Health clinic completed three urological questionnaires (International Index of Erectile Function [IIEF-5], International Prostate Symptom Score [IPSS], and Androgen Deficiency in Aging Males [ADAM]); and four non-urological questionnaires (Patient Health Questionnaire for depression [PHQ-9], STOP-BANG Sleep Apnea [OSA STOP-BANG], Insomnia Severity Index [ISI], and Epworth Sleepiness Scale [ESS]). Questionnaire results were evaluated in conjunction with patient clinical history and associated laboratory values via univariate and multivariate analysis. The mean age of the study participants was 54.1 years (SD 16). Comorbidities included hypertension (22.5%), vascular disease (15%), and diabetes mellitus (13.3%). Body Mass Index (BMI) was >25 in 77.3%. IIEF-5 scores were moderate-severe in 47.9%, ADAM questionnaire was positive in 79%, and IPSS scores were moderate-severe in 42.9% of patients. PHQ-9 demonstrated mild-severe depression in 38.6%, STOP-BANG showed intermediate-high risk for sleep apnea in 55.2%, ISI indicated moderate-severe insomnia in 18.1%, and ESS revealed mild-severe sleepiness in 16.6% of participants. On univariate analysis, BMI was associated with scores on the PHQ-9 (p = 0.035), STOP-BANG (p < 0.001), and ESS (p < 0.006). On multivariate analysis, positive ADAM questionnaire was associated with STOP-BANG (OR 3.29, 95% CI: 1.012-10.69), and IPSS with PHQ-9 (OR 4.64, 95% CI: 1.40-15.43) and ISI (OR 3.27, 95% CI: 1.06-10.1). Overall, patients presenting to a Men's Health Clinic were found to have high prevalence rates for risk of depression, insomnia and sleep apnea. Risks were elevated in older subjects, and those with increased BMI, hypogonadism, and lower urinary tract symptoms. Appropriate screening and referral to appropriate specialists are encouraged.

RESUMO

INTRODUCTION: Variability in the success rates for the endoscopic correction of vesicoureteral reflux (VUR) has prompted a debate regarding the use of routine postoperative voiding cystourethrogram (VCUG). This study examines the predictive performance of intraoperative mound morphology (IMM) and the presence of a postoperative ultrasound mound (PUM) on radiologic success, as well as investigates the role of using these two predictive factors as a composite tool to predict VUR resolution after endoscopic treatment. METHODS: This retrospective study included children with primary VUR who underwent endoscopic correction with a double hydrodistension-implantation technique (HIT) and dextranomer/hyaluronic acid copolymer. IMM was assessed intraoperatively. The presence of a PUM and VUR resolution were assessed by postoperative ultrasound (US) and VCUG, respectively. Radiologic success was defined as VUR resolution. RESULTS: A total of 70 children (97 ureters) were included in the study. The overall radiologic success rate was 83.5%. There was no statistically significant association between radiologic success and IMM (85.2% with excellent and 87.5% with "other" morphology; p=0.81). The sensitivity and specificity of PUM for radiologic success in this study was 98% and 71%, respectively, while the sensitivity and specificity of the combined prediction model were 81.9% and 85.7%, respectively. CONCLUSIONS: We objectively demonstrated that IMM was a poor predictor of radiologic success and should be used with caution. In addition, the performance of a combined prediction model was inferior to the presence of a PUM alone. As such, selective use of postoperative VCUG may be guided solely by the presence of a PUM.

RESUMO

INTRODUCTION: Antenatal hydronephrosis is a steady source of urology referrals since the era of routine fetal ultrasonography. Although most resolve, there are no guidelines for follow-up. OBJECTIVE: Our goal is to define safe parameters with which patients can be discharged early and avoid unnecessary follow-up. METHODS: We retrospectively reviewed all patients referred to a single children's referral hospital center for isolated antenetal hydronephrosis between 2010 and 2012. We looked at patients and renal units separately and divided the cohort into two groups for comparison. Our analysis endpoint is progression. That is, if the initial postnatal anterior-posterior diameter (APD) is less than 10 mm, progression occurs if the APD increases to 10 mm or above upon follow-up. Conversely, if the initial APD is 10 mm or more in at least one renal unit, progression occurs if the APD remains at 10 mm or above upon follow-up. RESULTS: There majority of the 186 patients and 308 renal units included in the analysis, were classified in the APD less than 10 mm group. Most renal units in the APD of less than 10 mm group were of SFU grades 0-2 (92.1%) and most of the renal units in the APD of 10 mm or greater group were of SFU grades 3-4 (60%) (Table). Only 19 renal units (6.2%) underwent pyeloplasty, and they were all from the APD of 10 mm or greater group and classified as SFU grade 3-4. No renal unit with an APD of less than 10 mm, nor any with an APD of 10 mm or greater and a SFU grade 0-2 underwent pyeloplasty. More than half of the renal units' hydronephrosis resolved in the APD of 10 mm or greater group, in comparison with 96.1% of the APD of less than 10 mm group. On multivariate analysis, patients with an APD of 10 mm or greater were 7.76 times more likely to show progression (p = 0.0006). CONCLUSION: An initial postnatal APD of 10 mm or greater, with a SFU grade 3-4, merits follow-up. However, all patients with an APD of less than 10 mm, especially when with a SFU grade 1-2, can be safely discharged as they are unlikely to experience complications.

RESUMO

PURPOSE OF REVIEW: Rhodiola rosea extracts have been used as a dietary supplement in healthy populations, including athletes, to non-specifically enhance the natural resistance of the body to both physical and behavior stresses for fighting fatigue and depression. We summarize the information with respect to the new pharmacological activities of Rhodiola rosea extracts and its underlying molecular mechanisms in this review article. RECENT FINDINGS: In addition to its multiplex stress-protective activity, Rhodiola rosea extracts have recently demonstrated its anti-aging, anti-inflammation, immunostimulating, DNA repair and anti-cancer effects in different model systems. Molecular mechanisms of Rhodiola rosea extracts's action have been studied mainly along with one of its bioactive compounds, salidroside. Both Rhodiola rosea extracts and salidroside have contrast molecular mechanisms on cancer and normal physiological functions. For cancer, Rhodiola rosea extracts and salidroside inhibit the mTOR pathway and reduce angiogenesis through down-regulation of the expression of HIF-1α/HIF-2α. For normal physiological functions, Rhodiola rosea extracts and salidroside activate the mTOR pathway, stimulate paracrine function and promote neovascularization by inhibiting PHD3 and stabilizing HIF-1α proteins in skeletal muscles. In contrast to many natural compounds, salidroside is water-soluble and highly bioavailable via oral administration and concentrated in urine by kidney excretion. SUMMARY: Rhodiola rosea extracts and salidroside can impose cellular and systemic benefits similar to the effect of positive lifestyle interventions to normal physiological functions and for anti-cancer. The unique pharmacological properties of Rhodiola rosea extracts or salidroside deserve further investigation for cancer chemoprevention, in particular for human urinary bladder cancer.
