RESUMO

OBJECTIVE: Prostate cancer is the most common malignancy among men and following a positive prostate-specific antigen (PSA) screening test, patients may undergo more expensive diagnostic testing. However, testing-related out-of-pocket costs (OOPCs), which may preclude patients from completing the screening process, have not been previously quantified. OOPCs for follow-up diagnostic testing (i.e., prostate biopsy and/or magnetic resonance imaging [MRI]) in patients with private insurance undergoing prostate cancer screening were estimated. METHODS: Men ages 55 to 69 years old who underwent PSA-based prostate cancer screening from 2010 to 2020 from the IBM Marketscan database were identified. The number of patients undergoing follow-up diagnostic testing within 12 months of screening was tabulated, dividing patients into three groups: (1) biopsy only, (2) MRI only, and (3) MRI + biopsy. Over the study period, patients with nonzero cost-sharing and calculated inflation-adjusted OOPCs, adding copayment, coinsurance, and deductible payments, for each group were identified. RESULTS: Among screened patients (n = 3,075,841) from 2010 through 2020, 91,850 had a second PSA test and an elevated PSA level, of which 40,329 (43.9%) underwent subsequent diagnostic testing. More than 75% of these patients experienced cost-sharing, and median OOPCs rose substantially over the study period for patients undergoing biopsy only ($79 to $214), MRI only ($81 to $490), and MRI and biopsy ($353 to $620). CONCLUSIONS: OOPCs from diagnostic testing after prostate cancer screening are common and rising. This work aligns with the recent position statement from the American Cancer Society, that payers should eliminate cost-sharing, which may undermine the screening process, for diagnostic testing following cancer screening.

RESUMO

OBJECTIVE: To examine the impact of increased compliance to contemporary perioperative care measures, as outlined by enhanced recover after surgery (ERAS) guidelines, among patients undergoing radical cystectomy (RC). PATIENTS AND METHODS: From the National Surgical Quality Improvement Program database we captured patients undergoing RC between 2019 and 2021. We identified five perioperative care measures: regional anaesthesia block, thromboembolism prophylaxis, ≤24 h perioperative antibiotic administration, absence of bowel preparation, and early oral diet. We stratified patients by the number of measures utilised (one to five). Statistical endpoints included 30-day complications, hospital length of stay (LOS), readmissions, and optimal RC outcome. Optimal RC outcome was defined as absence of any postoperative complication, re-operation, prolonged LOS (75th percentile, 8 days) with no readmission. Multivariable regressions with Bonferroni correction were performed to assess the association between use of contemporary perioperative care measures and outcomes. RESULTS: Of the 3702 patients who underwent RC, 73 (2%), 417 (11%), 1010 (27%), 1454 (39%), and 748 (20%) received one, two, three, four, and five interventions, respectively. On multivariable analysis, increased perioperative care measures were associated with lower odds of any complication (odds ratio [OR] 0.66, 99% confidence interval [CI] 0.6-0.73), and shorter LOS (ß -0.82, 99% CI -0.99 to -0.65). Furthermore, patients with increased compliance to contemporary care measures had increased odds of an optimal outcome (OR 1.38, 99% CI 1.26-1.51). CONCLUSIONS: Among the measures we assessed, greater adherence yielded improved postoperative outcomes among patients undergoing RC. Our work supports the efficacy of ERAS protocols in reducing the morbidity associated with RC.

RESUMO

AbstractThe American Urological Association (AUA) and American College of Surgeons (ACS) codes of professionalism require surgeons to disclose the specific roles and responsibilities of trainees to patients during the informed consent process. The objective of this study is to analyze how these requirements are met by urology training programs. An anonymous electronic survey was distributed to the program directors (PDs) of the 143 Accreditation Council for Graduate Medical Education urology residency programs in the United States in 2021. Information was collected regarding program demographics, aspects of the program's consent process, and the disclosure to patients of the role and participation of residents in their surgery. There were 49 responses to the survey (34.3% response rate). Nearly 70 percent of PDs reported that attending physicians lead the consent process. The topics covered during consent discussion include possible complications (25%), expected recovery time (23%), length of the surgery (22%), the people involved (18%), and their specific roles (7%). Many PDs do not explicitly discuss trainee involvement (48.8%) or when a resident is to perform the majority of the case (87.8%). The majority of PDs (78.8%) communicate medical student involvement, but 73.2 percent reported having a patient decline participation of a trainee after describing their role. Despite the AUA and ACS codes of professionalism, many urologists do not disclose resident involvement in surgery to patients. Further discussions are needed to explore how to better balance resident education and patient autonomy.

RESUMO

PURPOSE OF REVIEW: The genomic and immunologic profiling of renal cell carcinoma (RCC) has provided the impetus for advancements in systemic treatments using combination therapy - either with immune check point inhibitor (ICI) + ICI or with ICI + targeted therapy. This approach has been examined in several landmark trials, treating both clear cell (ccRCC) and nonclear cell (nccRCC) histologies. In this review, we highlight systemic therapy advancements made in this new decade, the 2020s. RECENT FINDINGS: Targeting the programmed death receptor 1/PD-L1 pathway has created more tolerable and effective immunotherapy regimens, expanding the applications of ICIs. These new applications, paired with trial data, include ICI monotherapy in nccRCC and adjuvant pembrolizumab in resected, high-risk RCC. In addition, ICI + ICI and ICI + TKI combination therapy have demonstrated oncologic efficacy in advanced ccRCC and sarcomatoid RCC. Similar progress has been noted regarding new targeted therapies. Along the hypoxia inducible factor pathway, belzutifan has received FDA approval in von Hippel-Lindau-associated RCC. In addition, in papillary RCC, agents such as cabozantinib target the MET proto-oncogene pathway and have demonstrated impressive oncologic outcomes. SUMMARY: The 2020s utilize the molecular profiling of advanced RCC as a scaffold for recent trials in immunotherapy and targeted therapies. Going forward, emphasizing patient-reported outcomes and careful clinical trial construction remain critical to improve systemic therapy in RCC.

RESUMO

PURPOSE: The American Urological Association (AUA) Annual Meeting serves as the premier platform for presenting unpublished research in urology. Among selected abstracts, podium presentations represent the most impactful submissions. While podium presentations receive a large audience through conference attendance and social media posts, it is unclear how often they manifest as publications in peer-reviewed journals. MATERIALS AND METHODS: Podium presentations from the 2017 AUA Annual Meeting were reviewed. Abstracts were assessed for publication between January 1, 2015 and May 31, 2020 allowing for a 3-year window of publication and accounting for publications prior to the submission deadline. Abstract authors were individually searched with key terms being added sequentially until <30 results were generated in PubMed®. Abstracts were deemed published if at least 1 author and 1 conclusion matched a manuscript. Publication rate, time to publication, and 2019 journal impact factor were collected. Statistical analysis was performed by linear and logistic regression. RESULTS: Of 872 podium presentations, 453 (51.9%) were published within 3 years. Median time from submission to publication was 12.5 months (IQR: 7.5-20.5). The number of articles published at 1, 2 and 3 years from submission was 203, 368 and 430, respectively. The median journal impact factor of publications was 3.2 (IQR: 2.0-5.8). Oncology studies (OR=1.21 [95% CI: 0.91-1.60], p=0.186) had similar rates of publication compared to non-oncology studies. CONCLUSIONS: While AUA podium presentations disseminate valuable data, approximately half were not published in peer-reviewed journals within 3 years. Therefore, care must be taken when promoting findings or adopting new practices based on these presentations alone.

RESUMO

PURPOSE: Retroperitoneal lymph node dissection (RPLND) for men with clinical stage (CS) I or II testicular nonseminomatous germ cell tumor (NSGCT) has both staging and therapeutic implications. We aimed to investigate the impact of lymph node count (LNC) on outcome after primary RPLND for men with CS I or II NSGCT using a nationally representative data set. MATERIALS AND METHODS: A retrospective analysis of men who received a primary RPLND for CS I or II NSGCT was performed using the National Cancer Database. The Kaplan-Meier method was used to determine overall survival (OS) according to LNC. Logistic regression analyses were used to identify factors associated with LNC >20 and factors predictive of lymph node-positive (pN+) disease after primary RPLND. RESULTS: Of 1,376 men who comprised our analytical cohort, 50.1% and 49.9% had 1-20 lymph nodes (LNs) and >20 LNs removed, respectively. Five-year OS rates were 96.4% and 99.1% for men with 1-20 and >20 LNs resected, respectively (p=0.004). A higher proportion of men with >20 LNs removed were treated at academic centers, had private insurance, presented with higher AJCC (American Joint Committee on Cancer) CS and were more likely to have pN+ disease, compared to those with 1-20 LNs removed. Factors significantly associated with pN+ disease after RPLND include higher AJCC CS and LNC (per 10-count increase). CONCLUSIONS: Higher LNC after primary RPLND significantly increases the likelihood of identifying pN+ disease and is associated with improved OS. Our data support the therapeutic implications of a thoroughly performed RPLND in the primary setting.

RESUMO

PURPOSE OF REVIEW: As molecular profiling of renal cell carcinoma (RCC) continues to elucidate novel targets for nonclear cell histologies, understanding the landscape of these targets is of utmost importance. In this review, we highlight the genomic landscape of nonclear cell RCC and its implications for current and future systemic therapies. RECENT FINDINGS: Several genomic studies have described the mutational burden among nonclear cell histologies. These studies have highlighted the importance of MET in papillary RCC and led to several clinical trials evaluating the efficacy of MET inhibitors for papillary RCC. The success of immune checkpoint inhibitors, such as ipilimumab and nivolumab, in clear cell RCC has led to ongoing trials evaluating these novel therapeutics in nonclear cell RCC. SUMMARY: Genomic profiling has allowed for the evaluation of novel targets for nonclear cell RCC. This evolving therapeutic landscape is being explored in promising, ongoing trials that have the potential for changing how nonclear cell RCC is managed.

RESUMO

OBJECTIVES: The aetiology of primary chronic pain syndromes (CPS) is highly disputed. We performed a systematic review and meta-analysis aiming to assess differences in circulating cytokine levels in patients with diffuse CPS (fibromyalgia) vs healthy controls (HC). METHODS: Human studies published in English from the PubMed, MEDLINE/Scopus and Cochrane databases were systematically searched from inception up to January 2020. We included full text cross-sectional or longitudinal studies with baseline cytokine measurements, reporting differences in circulating cytokine levels between fibromyalgia patients and HC. Random-effects meta-analysis models were used to report pooled effects and 95% CIs. This study is registered with PROSPERO (CRD42020193774). RESULTS: Our initial search yielded 324 papers and identified 29 studies (2458 participants) eligible for systematic review and 22 studies (1772 participants) suitable for meta-analysis. The systematic analysis revealed reproducible findings supporting different trends of cytokine levels when fibromyalgia patients were compared with HC, while the chemokine eotaxin, was consistently raised in fibromyalgia. Meta-analysis showed significantly increased TNF-α [standardized mean difference (SMD) = 0.36, 95% CI: 0.12, 0.60, P = 0.0034; I2 = 71%, Q2P = 0.0002], IL-6 (SMD = 0.15, 95% CI: 0.003, 0.29, P = 0.045; I2 = 39%, Q2P = 0.059), IL-8 (SMD = 0.26, 95% CI: 0.05, 0.47, P = 0.01; I2 = 61%, Q2P = 0.005) and IL-10 (SMD = 0.61, 95% CI: 0.34, 0.89, P < 0.001; I2 = 10%, Q2P = 0.34) in fibromyalgia patients compared with HC. CONCLUSION: We found evidence of significant differences in the peripheral blood cytokine profiles of fibromyalgia patients compared with HC. However, the distinctive profile associated with fibromyalgia includes both pro-inflammatory (TNF-α, IL-6, IL-8) and anti-inflammatory (IL-10) cytokines in pooled analysis, as well as chemokine (eotaxin) signatures. Further research is required to elucidate the role of cytokines in fibromyalgia.

RESUMO

PURPOSE OF REVIEW: Pheochromocytoma and paraganglioma (PPGLs) are neuroendocrine tumors with diverse clinical presentations. PPGLs can be sporadic but often are associated with various syndromes, which can have variable clinical presentations. A thorough workup is therefore critical for staging, treatment, and follow-up. Imaging is an essential part of the workup and diagnosis of PPGLs. RECENT FINDINGS: Improvements in cross-sectional imaging with radionuclides have increased specificity and sensitivity for identifying and treating PPGLs. Furthermore, a variety of targets on PPGLs has allowed for optimal imaging with radionuclides that can be used for staging and treatment. Currently, radionuclides are being evaluated for staging and treatment of PPGLs. Developing novel radionuclides that can identify disease sites and target them simultaneously provides a potential for improving survival and outcomes in patients with PPGLs. Given the clinical diversity among PPGLs, expanding the therapeutic arsenal against locally advanced or metastatic PPGLs can allow clinicians to evaluate and treat PPGLs thoroughly.

RESUMO

BACKGROUND: Stage III renal cell carcinoma (RCC) encompasses both lymph node-positive (pT1-3N1M0) and lymph node-negative (pT3N0M0) disease. However, prior institutional studies have indicated that among patients with stage III disease, those with lymph node disease have worse oncologic outcomes and experience survival that is similar to that of patients with American Joint Committee on Cancer (AJCC) stage IV disease. The objective of the current study was to validate these findings using a large, nationally representative sample of patients with kidney cancer. METHODS: Patients with AJCC stage III or stage IV RCC were identified using the National Cancer Data Base (NCDB). Patients were categorized as having lymph node-positive stage III (pT1-3N1M0), lymph node-negative stage III (pT3N0M0), or stage IV metastatic (pT1-3 N0M1) disease. Cox proportional hazards models compared outcomes while adjusting for comorbidities. Kaplan-Meier estimates illustrated relative survival when comparing staging groups. RESULTS: A total of 8988 patients met the inclusion criteria, with 6587 patients classified as having lymph node-negative stage III disease, 2218 as having lymph node-positive stage III disease, and 183 as having stage IV disease. Superior survival was noted among patients with lymph node-negative stage III disease, but similar survival was noted between patients with lymph node-positive stage III and stage IV RCC, with 5-year survival rates of 61.9% (95% confidence interval [95% CI], 60.3%-63.4%), 22.7% (95% CI, 20.6%-24.9%), and 15.6% (95% CI, 11.1%-23.8%), respectively. CONCLUSIONS: Current RCC staging systems group pT1-3N1M0 and pT3N0M0 disease as stage III disease. However, the results of the current validation study suggest the need for further stratification and even placement of patients with pT1-3N1M0 disease into the stage IV category. Staging that accurately reflects oncologic prognosis may help clinicians better counsel and select patients who might derive the most benefit from lymphadenectomy, adjuvant systemic therapy, more rigorous imaging surveillance, and clinical trial participation.

RESUMO

OBJECTIVES: To explore the comparative effectiveness of partial nephrectomy (PN), radical nephrectomy (RN), ablative therapies (ablation) and active surveillance (AS) for small renal masses (SRMs; tumour diameter ≤4.0 cm) in the domains of survival, renal function and quality of life (QoL) using the prospectively maintained Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) Registry. PATIENTS AND METHODS: Estimated glomerular filtration rate (eGFR) was calculated from creatinine values to determine renal function. QoL was measured using the Short Form 12 (SF-12) questionnaire. The Kaplan-Meier method and Cox proportional hazards regression were used for survival analysis. The mixed-effects model was used for renal function and QoL analysis. RESULTS: Of 638 patients, 231 (36.2%) chose PN, 41 (6.4%) RN, 27 (4.2%) ablation and 339 (53.1%) AS. Cancer-specific survival at 7 years was 98.8% in PN patients and 100% in all other groups. Overall survival (OS) at 7 years was 87.9%, 90.2%, 83.5% and 66.1% in PN, RN, ablation and AS patients, respectively. The OS rate was significantly worse in the AS group than other groups and likely attributable to older age and increased comorbidities. The eGFR was lowest in RN patients but comparable in all other groups. QoL was lowest in AS patients due to lower physical health scores, but mental health scores were similar in all groups. CONCLUSIONS: With excellent oncological outcomes in all groups, nephron-sparing approaches, like PN and ablation, are preferred over RN when intervention is indicated for SRMs. AS is a reasonable option for select patients, given the comparable oncological and mental health outcomes.

RESUMO

BACKGROUND: In this era of precision medicine, the DNA damage response (DDR) pathway has been shown to be a viable target of intervention in metastatic castration-resistant prostate cancer (CRPC) as approximately one-third of CRPC patients harbor DDR pathway mutations. To determine whether DDR pathway is a potential therapeutic target in localized disease, we analyzed The Cancer Genome Atlas (TCGA) in the present study. METHODS: TCGA is a publically available cancer genome database that is sponsored by the United States National Cancer Institute. Total of 455 cases were available in the database at the time of this analysis. RESULTS: DDR pathway gene mutations or copy number alterations were present in 136 (29.9%) of the 455 cases. On a univariate analysis, DDR pathway status did not correlate with serum prostate specific antigen, tumor stage or grade. However, among patients with high-risk features post-operatively (pathologic stage ≥ T3, Gleason score ≥ 8, or PSA > 20 ng/ml), DDR pathway alteration was associated with a lower overall survival (p = 0.0291). CONCLUSIONS: Collectively these results suggest that DDR pathway alterations may also be significant in localized prostate cancer and agents such as PARP inhibitors should be considered in patients with a high-risk disease.

RESUMO

OBJECTIVES: To determine the performance of Prostate Health Index (PHI) density (PHID) combined with MRI and prior negative biopsy (PNB) status for the diagnosis of clinically significant prostate cancer (PCa). PATIENTS AND METHODS: Patients without a prior diagnosis of PCa, with elevated prostate-specific antigen and a normal digital rectal examination who underwent PHI testing prospectively prior to prostate biopsy were included in this study. PHID was calculated retrospectively using prostate volume derived from transrectal ultrasonography at biopsy. Univariable and multivariable logistic regression modelling, along with receiver-operating characteristic (ROC) curve analysis, was used to determine the ability of serum biomarkers to predict clinically significant PCa (defined as either grade group [GG] ≥2 disease or GG1 PCa detected in >2 cores or >50% of any one core) on biopsy. Age, PNB status and Prostate Imaging Reporting and Data System (PI-RADS) score were incorporated into the regression models. RESULTS: Of the 241 men who qualified for the study, 91 (37.8%) had clinically significant PCa on biopsy. The median (interquartile range) PHID was 0.74 (0.44-1.24); it was 1.18 (0.77-1.83) and 0.55 (0.38-0.89) in those with and without clinically significant PCa on biopsy, respectively (P < 0.001). On univariable logistic regression, age and PNB status were associated with clinically significant cancer. Of the tested biomarkers, PHID demonstrated the highest discriminative ability for clinically significant disease (area under the ROC curve [AUC] 0.78 for the univariable model). That continued to be the case in multivariable logistic regression models incorporating age and PNB status (AUC 0.82). At a threshold of 0.44, representing the 25th percentile of PHID in the cohort, PHID was 92.3% sensitive and 35.3% specific for clinically significant PCa; the sensitivity and specificity were 93.0% and 32.4% and 97.4% and 29.1% for GG ≥2 and GG ≥3 disease, respectively. In the 104 men who underwent MRI, PI-RADS score was complementary to PHID, with a PI-RADS score ≥3 or, if PI-RADS score ≤2, a PHID ≥0.44, detecting 100% of clinically significant disease. For that subgroup, of the biomarkers tested, PHID (AUC 0.90) demonstrated the highest discriminative ability for clinically significant disease on multivariable logistic regression incorporating age, PNB status and PI-RADS score. CONCLUSIONS: In this contemporary cohort of men undergoing prostate biopsy for the diagnosis of PCa, PHID outperformed PHI and other PSA derivatives in the diagnosis of clinically significant cancer. Incorporating age, PNB status and PI-RADS score led to even further gains in the diagnostic performance of PHID. Furthermore, PI-RADS score was found to be complementary to PHID. Using 0.44 as a threshold for PHID, 35.3% of unnecessary biopsies could have been avoided at the cost of missing 7.7% of clinically significant cancers. Despite these encouraging results, prospective validation is needed.

RESUMO

PURPOSE: While retroperitoneal lymph node dissection (RPLND) is traditionally reserved for nonseminomatous germ cell tumors, recent efforts to reduce long-term toxicities of radiation and chemotherapy have turned attention to its application for testicular seminomas. Currently, RPLND is reserved for the post-chemotherapy for stage II testicular seminomas; we aimed to describe current utilization of RPNLD for testicular seminomas by stage and implications for survival. METHODS: A national sample of men diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminoma (1988-2013) was evaluated from SEER Program registries. Stage-specific utilization of RPLND was determined. Cox proportional hazards models, adjusted for age, race, and radiotherapy, evaluated overall (OS) and cancer-specific survival (CSS) for the RPLND cohort. Adjusted models assessed predictors of RPLND. RESULTS: A total of 17,681 men (mean age 38.1 years) with testicular seminoma were included with low utilization of RPLND for stage I disease (1.3% overall) and higher rates for stage II disease (10.6% overall). There were no appreciable trends over time. Patients receiving RPLND did not appear to have worse OS or CSS on adjusted stage-by-stage analysis. Higher stage disease (IIA-IIC) was associated with greater need for RPLND while radiotherapy was associated with decreased use [OR 0.40 (0.32-0.51), p < 0.001]. CONCLUSIONS: Utilization of RPLND for testicular seminomas in the post-chemotherapy setting has remained stable over a 25-year period. Patients undergoing RPLND are a higher risk cohort but stage-by-stage survival outcomes appeared comparable to men not undergoing RPLND. Upcoming trials implementing RPLND as a first-line modality for testicular seminoma or isolated retroperitoneal relapse will help better quantify relative recurrence and survival.

RESUMO

OBJECTIVE: To assess textbook outcomes by hospital teaching status following major surgery for urologic cancers. METHODS: We used 100% national Medicare Provider Analysis and Review files from 2017-2020 to assess rates of textbook outcomes in patients undergoing bladder (ie, radical cystectomy), kidney (ie, radical or partial nephrectomy), and prostate (ie, radical prostatectomy) surgery for genitourinary malignancies. The extent of integration of learners into each hospital's workforce-defined as major, minor, and non teaching hospitals-was the primary exposure. A textbook outcome, measured at the patient level, was defined as the absence of in-hospital mortality and mortality within 30days of surgery, no readmission 30days following discharge, no postoperative complication, and no prolonged length of stay. RESULTS: Textbook outcomes were achieved in 51% (8564/16,786) of patients after bladder cancer surgery, 70% (39,938/57,300) of patients after kidney cancer surgery, and 82% (50,408/61,385) of patients after prostate cancer surgery. After adjusting for patient- and hospital-level characteristics, teaching hospitals had higher rates of textbook outcomes in those undergoing bladder (50.7% vs 44.0%; P = .001), kidney (72.0% vs 69.7%; P = .02), and prostate (85.3% vs 81.0%; P <.001) surgery. This effect was attenuated, but not eliminated, by surgical volume in additional sensitivity analyses for bladder (OR: 1.20, 95% CI: 1.00-1.42; P = .04) and prostate (OR: 1.15, 95% CI: 1.00-1.32; P = .04) surgery. There were no significant differences in kidney cancer surgery outcomes after adjusting for hospital volume (OR: 1.03, 95% CI: 0.93-1.14; P = .6). CONCLUSION: Undergoing major cancer surgery at a teaching hospital was associated with an increased likelihood of achieving a textbook outcome. This effect was attenuated by volume but persisted for bladder and prostate surgery.
