RESUMO

PURPOSE: Immigrants constitute 14% of the U.S. population, and this group is especially vulnerable to poor health care access. Prior research demonstrates U.S. immigrants have low rates of guideline-concordant breast and colorectal screening, but prostate cancer screening has not previously been evaluated. We sought to characterize screening behaviors among U.S. immigrants and to consider possible mechanisms to enhance PSA-based screening for this population. MATERIALS AND METHODS: Data were obtained from the 2010, 2013, 2015, and 2018 National Health Interview Survey reports, which were the recent survey years that included questions about PSA testing. Complex samples logistic regression was performed to assess the relationship between immigrant-specific characteristics including region of birth, citizenship status, length of residence within the U.S., English language proficiency, and history of PSA testing. RESULTS: There were 22,997 survey respondents; 3,257 were foreign-born and 19,740 were U.S.-born. Rates of PSA testing were much lower among the foreign-born population compared to the U.S.-born population (43% vs 60%). Citizenship status, length of residence in the U.S. for more than 15 years, and English proficiency were directly linked to increased rates of PSA testing. There was significant variability in PSA testing among immigrant subgroups and Asian immigrants had the lowest rate of PSA testing. Annual physician visits and English language proficiency were associated with increased PSA testing among the U.S. immigrant population. CONCLUSIONS: Immigrants have relatively low rates of PSA testing. Improving health care utilization and language services may help to narrow the gap in guideline-concordant prostate cancer screening between immigrants and nonimmigrants.

RESUMO

BACKGROUND: Prostate cancer (PrCa) is one of the most genetically driven solid cancers with heritability estimates as high as 57%. Men of African ancestry are at an increased risk of PrCa; however, current polygenic risk score (PRS) models are based on European ancestry groups and may not be broadly applicable. The objective of this study was to construct an African ancestry-specific PrCa PRS (PRState) and evaluate its performance. METHODS: African ancestry group of 4,533 individuals in ELLIPSE consortium was used for discovery of African ancestry-specific PrCa SNPs. PRState was constructed as weighted sum of genotypes and effect sizes from genome-wide association study (GWAS) of PrCa in African ancestry group. Performance was evaluated using ROC-AUC analysis. RESULTS: We identified African ancestry-specific PrCa risk loci on chromosomes 3, 8, and 11 and constructed a polygenic risk score (PRS) from 10 African ancestry-specific PrCa risk SNPs, achieving an AUC of 0.61 [0.60-0.63] and 0.65 [0.64-0.67], when combined with age and family history. Performance dropped significantly when using ancestry-mismatched PRS models but remained comparable when using trans-ancestry models. Importantly, we validated the PRState score in the Million Veteran Program (MVP), demonstrating improved prediction of PrCa and metastatic PrCa in individuals of African ancestry. CONCLUSIONS: African ancestry-specific PRState improves PrCa prediction in African ancestry groups in ELLIPSE consortium and MVP. This study underscores the need for inclusion of individuals of African ancestry in gene variant discovery to optimize PRSs and identifies African ancestry-specific variants for use in future studies.

RESUMO

PURPOSE: Medicaid expansion under the Patient Protection and Affordable Care Act occurred almost concurrently with 2012 U.S. Preventive Services Task Force recommendations against prostate specific antigen screening. Here the relative influence on prostate specific antigen screening rates by 2 concurrent and opposing system-level policy initiatives is investigated: improved access to care and change in clinical practice guidelines. MATERIALS AND METHODS: Behavioral Risk Factor Surveillance System data from years 2012 to 2018 were analyzed for trends in self-reported prostate specific antigen screening and insurance coverage. Subanalyses included state Medicaid expansion status and respondent federal poverty level. Multivariable logistic regression was performed to evaluate factors associated with prostate specific antigen screening. RESULTS: From 2012 to 2018 prostate specific antigen screening predominantly declined with a notable exception of an increase of 7.3% for men at <138% federal poverty level between 2011 and 2013 in early expansion states. Initial increases did not continue, and screening trends mirrored those of nonexpansion states by 2018. Notably, 2014 planned expansions states did not follow this trend with minimal change between 2015 and 2017 compared to declines in early expansion states and nonexpansion states (-0.4% vs -6.7% and -8.6%, respectively). CONCLUSIONS: Medicaid expansion was associated with increased rates of insured men at <138% federal poverty level from 2012 to 2018 in early expansion states. In this group, initial increases in prostate specific antigen screening were not durable and followed the trend of reduced screening seen across the United States. In planned expansions states the global drop in prostate specific antigen screening from 2016 to 2018 was offset in men at <138% federal poverty level by expanding access to care. Nonexpansion states showed a steady decline in prostate specific antigen screening rates. This suggests that policy such as U.S. Preventive Services Task Force recommendations against screening competes with and often outmatches access to care.

RESUMO

PURPOSE: Implementation of survivorship care plans has been emphasized as a key component to improving care for cancer survivors. Our objective was to determine the prevalence of survivorship care plan receipt for survivors of genitourinary malignancy including kidney, prostate and bladder cancer, and evaluate whether receipt was associated with a measurable health benefit. MATERIALS AND METHODS: Data from the Behavioral Risk Factor Surveillance System Cancer Survivorship modules in 2012, 2014, 2016 and 2017 were analyzed. The proportion of patients with bladder, kidney or prostate cancer receiving a survivorship care plan was calculated. Complex samples multivariable logistic regressions were performed to determine the association of survivorship care plan receipt with sociodemographic variables, and assess the relationship between survivorship care plan receipt and self-reported health status (general, physical and mental). RESULTS: Survivorship care plan distribution increased from 27.5% in 2012 to 39.5% in 2017. Patients with low income, less formal education and extremes of age were less likely to receive a survivorship care plan. Those receiving a survivorship care plan were less likely to report poor physical health (OR 0.70, CI 0.52-0.96, p=0.026). Subanalysis showed a similar result for physical health of patients with prostate cancer (OR 0.68, CI 0.48-0.96, p=0.030) and general health of patients with kidney cancer (OR 0.37, CI 0.19-0.75, p=0.006). CONCLUSIONS: Distribution of survivorship care plans to genitourinary malignancy survivors has increased since 2012 in response to advocacy from national organizations. Nonetheless, utilization is low and there is heterogeneity in the populations likely to receive a survivorship care plan. There is a measurable association between survivorship care plans and improved health status but further study is needed to determine causality.

RESUMO

OBJECTIVES: Early surgical resection remains the recommended treatment option for most small renal mass (≤4 cm). We examined the long-term overall survival (OS) of patients managed with delayed and immediate nephrectomy of cT1a renal cancer. PATIENT AND METHODS: We utilized the National Cancer Database (2005-2010) to identify 14,677 patients (immediate nephrectomy: 14,050 patients vs. late nephrectomy: 627 patients) aged <70 years with Charlson Comorbidity Index 0 and cT1aN0M0 renal cell carcinoma. Immediate nephrectomy and late nephrectomy were defined as nephrectomy performed <30 days and >180 days from diagnosis, respectively. Inverse probability of treatment weighting-adjusted Kaplan-Meier curves and Cox proportional hazards regression analyses were used to compare OS of patients in the 2 treatment arms. Influence of patient age and Charlson Comorbidity Index on treatment effect was tested by interactions. Sensitivity analysis was performed to explore the outcome of delaying nephrectomy for >12 months. RESULTS: Median patient age was 55 years with a median follow-up of 82.5 months. Inverse probability of treatment weighting-adjusted Kaplan-Meier curves suggest no significant difference between treatment arms (immediate nephrectomy [<30 days] vs. delayed nephrectomy [>180 days]) (Hazard ratio 0.96; 95% confidence interval 0.73-1.26; P = 0.77). This outcome was consistent between all patients regardless of age (P = 0.48). Sensitivity analysis reports no difference in OS even if nephrectomy was delayed by >12 months (P = 0.60). CONCLUSIONS: We report that delayed and immediate nephrectomy for cT1a renal cell carcinoma confers comparable long-term OS. These findings suggest that a period of observation of between 6 and 12 months is safe to allow identification of renal masses, which will benefit from surgical resection.

RESUMO

PURPOSE: Gleason 6 (3+3) is the most commonly diagnosed prostate cancer among men with prostate specific antigen screening, the most histologically well differentiated and is associated with the most favorable prognosis. Despite its prevalence, considerable debate exists regarding the genetic features, clinical significance, natural history, metastatic potential and optimal management. MATERIALS AND METHODS: Members of the Young Urologic Oncologists in the Society of Urologic Oncology cooperated in a comprehensive search of the peer reviewed English medical literature on Gleason 6 prostate cancer, specifically focusing on the history of the Gleason scoring system, histological features, clinical characteristics, practice patterns and outcomes. RESULTS: The Gleason scoring system was devised in the early 1960s, widely adopted by 1987 and revised in 2005 with a more restrictive definition of Gleason 6 disease. There is near consensus that Gleason 6 meets pathological definitions of cancer, but controversy about whether it meets commonly accepted molecular and genetic criteria of cancer. Multiple clinical series suggest that the metastatic potential of contemporary Gleason 6 disease is negligible but not zero. Population based studies in the U.S. suggest that more than 90% of men newly diagnosed with prostate cancer undergo treatment and are exposed to the risk of morbidity for a cancer unlikely to cause symptoms or decrease life expectancy. Efforts have been proposed to minimize the number of men diagnosed with or treated for Gleason 6 prostate cancer. These include modifications to prostate specific antigen based screening strategies such as targeting high risk populations, decreasing the frequency of screening, recommending screening cessation, incorporating remaining life expectancy estimates, using shared decision making and novel biomarkers, and eliminating prostate specific antigen screening entirely. Large nonrandomized and randomized studies have shown that active surveillance is an effective management strategy for men with Gleason 6 disease. Active surveillance dramatically reduces the number of men undergoing treatment without apparent compromise of cancer related outcomes. CONCLUSIONS: The definition and clinical relevance of Gleason 6 prostate cancer have changed substantially since its introduction nearly 50 years ago. A high proportion of screen detected cancers are Gleason 6 and the metastatic potential is negligible. Dramatically reducing the diagnosis and treatment of Gleason 6 disease is likely to have a favorable impact on the net benefit of prostate cancer screening.

RESUMO

PURPOSE: Cancer control of partial nephrectomy for high-risk localized renal cell carcinoma is unclear. To assess whether PN provides adequate cancer control in high-risk disease (HRD), survival outcomes were compared in both a population-based cohort and an institutional cohort. METHODS: Surveillance, Epidemiology, and End Results database and a prospectively maintained institutional database were queried for patients with RCC who underwent PN or RN for a localized tumor ≤7 cm and were found to have high-grade and/or high-stage disease (HRD). Cancer-specific (CSS) or recurrence-free survival (RFS) and overall survival (OS) were primary outcomes measured and were compared between those who underwent PN and RN using multivariable Cox proportional hazards and propensity analysis. RESULTS: The population cohort consisted of 12,757 (24.9 %) patients with HRD, 85.2 and 14.8 % of which underwent RN and PN, respectively. RN was not associated with CSS (HR 1.23, p = 0.08) but was independently associated with poor OS (HR 1.16, p = 0.031). Propensity analysis showed that RN resulted in a 20 % increased risk of death from all causes (p = 0.008). In the institutional cohort, of 317 patients, 35.9 % had HRD, 56 and 52 of which underwent RN and PN, respectively. Adjusting for age-adjusted Charlson index, RN was a predictor of poor OS (OR 6.20, p = 0.041). Propensity analysis showed that RFS and OS were not related to nephrectomy type (RN HR 0.65, p = 0.627 and RN HR 1.70, p = 0.484). CONCLUSIONS: In patients with pathologic high-risk RCC, partial excision is associated with similar cancer control as compared to radical excision.

RESUMO

OBJECTIVE: To examine the rates of hospitalization in patients with metastatic prostate cancer (mCaP), as well as the effect of hospice utilization on the cost patterns of mCaP. Over the past decade, dramatic changes in the management of advanced prostate cancer have proceeded alongside changes in end-of-life care. But, the impact of these contemporary advances in management of mCaP and its implications on US health care expenditure remains unknown. METHODS: Patients hospitalized with mCaP from 1998 to 2010 were extracted from the Nationwide Inpatient Sample (n = 100,220). Temporal trends in incidence and charges were assessed by linear regression. Complex samples logistic regression models were used to identify the predictors of in-hospital mortality, elevated hospital charges beyond the 75th percentile and hospice utilization. RESULTS: Between 1998 and 2010, admissions for mCaP decreased at a rate of -5.95% per year (P <.001), whereas per-incident charges increased at the rate of 6.1% (P <.001) annually; the national economic burden of care was stable. Over the study period, hospice use increased 488.0% per year (P <.001) but was significantly lower among black (odds ratio [OR], 0.73; P = .01) and Hispanic (OR, 0.65; P = .03) patients. In multivariable analyses, hospice utilization was associated with decreased odds of elevated hospital charges beyond the 75th percentile (OR, 0.84; P = .02). CONCLUSION: Despite a decline in hospitalizations for mCaP, the economic burden of care has remained stable. Increasing use of hospice services has moderated the effect of rising per-incident hospital charges, highlighting the importance of promoting access to hospice in the right clinical setting. These findings have important policy implications, particularly as advances in treatment are expected to further increase expenditures related to the inpatient management of mCaP.

RESUMO

BACKGROUND: Intracorporeal urinary diversion (ICUD) has the potential benefits of a smaller incision, reduced pain, decreased bowel exposure, and reduced risk of fluid imbalance. OBJECTIVE: To compare the perioperative outcomes of patients undergoing extracorporeal urinary diversion (ECUD) and ICUD following robot-assisted radical cystectomy (RARC). DESIGN, SETTING, AND PARTICIPANTS: We reviewed the database of the International Robotic Cystectomy Consortium (IRCC) (18 international centers), with 935 patients who had undergone RARC and pelvic lymph node dissection (PLND) between 2003 and 2011. INTERVENTION: All patients within the IRCC underwent RARC and PLND as indicated. The urinary diversion was performed either intracorporeally or extracorporeally. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Demographic data, perioperative outcomes, and complications in patients undergoing ICUD or ECUD were compared. All patients had at least a 90-d follow-up. The Fisher exact test was used to summarize categorical variables and the Wilcoxon rank sum test or Kruskal-Wallis test for continuous variables. RESULTS AND LIMITATIONS: Of 935 patients who had RARC and PLND, 167 patients underwent ICUD (ileal conduit: 106; neobladder: 61), and 768 patients had an ECUD (ileal conduit: 570; neobladder: 198). Postoperative complications data were available for 817 patients, with a minimum follow-up of 90 d. There was no difference in age, gender, body mass index, American Society of Anesthesiologists grade, or rate of prior abdominal surgery between the groups. The operative time was equivalent (414 min), with the median hospital stay being marginally longer for the ICUD group (9 d vs 8 d, p=0.086). No difference in the reoperation rates at 30 d was noted between the groups. The 90-d complication rate was not significant between the two groups, but a trend favoring ICUD over ECUD was noted (41% vs 49%, p=0.05). Gastrointestinal complications were significantly lower in the ICUD group (p ≤ 0.001). Patients with ICUD were at a lower risk of experiencing a postoperative complication at 90 d (32%) (odds ratio: 0.68; 95% confidence interval, 0.50-0.94; p=0.02). Being a retrospective study was the main limitation. CONCLUSIONS: Robot-assisted ICUD can be accomplished safely, with comparable outcomes to open urinary diversion. In this cohort, patients undergoing ICUD had a relatively lower risk of complications.

RESUMO

OBJECTIVE: To investigate gender effects on the type of nephrectomy performed for a stage I renal mass and differences that might account for disparity in treatment patterns according to gender. METHODS: Using a single-institution database, patients who underwent nephrectomy at a tertiary referral center for a localized, solitary tumor, ≤ 7 cm with a normal contralateral kidney were identified. Variables thought to affect selection for type of nephrectomy were compared between male and female patients. Using multivariable logistic regression, the effect of gender on the likelihood of radical vs partial nephrectomy and the likelihood of malignancy were assessed. Renal function outcomes were also compared. RESULTS: No difference between genders was seen in age, race, smoking status, body mass index, tumor size, RENAL score or operating surgeon. Only Charlson index and preoperative creatinine significantly differed with women having a more favorable comorbidity profile (Charlson >1 in 38% vs 50%; P = .027) and lower mean preoperative creatinine (0.09 ± 0.3 vs 1.1 ± 0.3; P <.001). Despite lower creatinine, women had inferior preoperative renal function with a mean estimated glomerular filtration rate of 71.4 ± 21 vs 78.9 ± 21 mL/min/1.73 m2 in men (P <.001). Multivariable analysis indicated that female patients were 2.5 times more likely to undergo radical nephrectomy compared with their male counterparts (P = .022). Women were less likely to have malignancy (odds ratio male gender 2.50; P = .013). CONCLUSION: Women are more likely than men to undergo radical vs partial excision of a localized renal mass, despite less comorbid burden, inferior renal function, and increased likelihood of benign disease.

RESUMO

BACKGROUND: Complication reporting is highly variable and nonstandardized. Therefore, it is imperative to determine the surgical outcomes of major oncologic procedures. OBJECTIVE: To describe the complications after robot-assisted radical cystectomy (RARC) using a standardized and validated reporting methodology. DESIGN, SETTING, AND PARTICIPANTS: Using the International Robotic Cystectomy Consortium (IRCC) database, we identified 939 patients who underwent RARC, had available complication data, and had at least 90 d of follow-up. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Complications were analyzed and graded according to the Memorial Sloan-Kettering Cancer Center (MSKCC) system and were defined and stratified by organ system. Secondary outcomes included identification of preoperative and intraoperative variables predicting complications. Logistic regression models were used to define predictors of complications and readmission. RESULTS AND LIMITATIONS: Forty-one percent (n=387) and 48% (n=448) of patients experienced a complication within 30 and 90 d of surgery, respectively. The highest grade of complication was grade 0 in 52%, grade 1-2 in 29%, and grade 3-5 in 19% patients. Gastrointestinal, infectious, and genitourinary complications were most common (27%, 23%, and 17%, respectively). On multivariable analysis, increasing age group, neoadjuvant chemotherapy, and receipt of blood transfusion were independent predictors of any and high-grade complications, respectively. Thirty and 90-d mortality was 1.3% and 4.2%, respectively. As a multi-institutional database, a disparity in patient selection, operating standards, postoperative management, and reporting of complications can be considered a major limitation of the study. CONCLUSIONS: Surgical morbidity after RARC is significant when reported using a standardized reporting methodology. The majority of complications are low grade. Strict reporting of complications is necessary to advocate for radical cystectomy (RC) and helps in patient counseling.

RESUMO

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Lymph node dissection and it's extend during robot-assisted radical cystectomy varies based on surgeon related factors. This study reports outcomes of robot-assisted extended lymphadenectomy based on surgeon experience in both academic and private practice settings. OBJECTIVE: To evaluate the incidence of, and predictors for, extended lymph node dissection (LND) in patients undergoing robot-assisted radical cystectomy (RARC) for bladder cancer, as extended LND is critical for the treatment of bladder cancer but the role of minimally invasive surgery for extended LND has not been well-defined in a multi-institutional setting. PATIENTS AND METHODS: Used the International Robotic Cystectomy Consortium (IRCC) database. In all, 765 patients who underwent RARC at 17 institutions from 2003 to 2010 were evaluated for receipt of extended LND. Patients were stratified by age, sex, clinical stage, institutional volume, sequential case number, and surgeon volume. Logistic regression analyses were used to correlate variables to the likelihood of undergoing extended LND. RESULTS: In all, 445 (58%) patients underwent extended LND. Among all patients, a median (range) of 18 (0-74) LNs were examined. High-volume institutions (≥100 cases) had a higher mean LN yield (23 vs 15, P < 0.001). On univariable analysis, surgeon volume, institutional volume, and sequential case number were associated with likelihood of undergoing extended LND. On multivariable analysis, surgeon volume [odds ratio (OR) 3.46, 95% confidence interval (CI) 2.37-5.06, P < 0.001] and institution volume [OR 2.65, 95% CI 1.47-4.78, P = 0.001) were associated with undergoing extended LND. CONCLUSIONS: Robot-assisted LND can achieve similar LN yields to those of open LND after RC. High-volume surgeons are more likely to perform extended LND, reflecting a correlation between their growing experience and increased comfort with advanced vascular dissection.

RESUMO

OBJECTIVES: The incidence of metastatic disease in patients with renal cell carcinoma (RCC) correlates with tumor size. We sought to determine the incidence of metastatic disease by tumor size, and the utilization and impact of nephron-sparing surgery on survival in those with metastatic disease. MATERIALS AND METHODS: Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, we identified 56,011 patients between 1988 and 2005 diagnosed with RCC. Patients were initially separated into two groups--those with and without metastatic disease--and stratified by tumor size. Cox proportional hazard modeling and Kaplan-Meier analyses were then utilized to evaluate the role of gender, age, grade, histology, tumor size, and type of surgery (radical vs. partial nephrectomy) on overall- and cancer-specific survival in patients with metastatic disease. RESULTS: Eight thousand four hundred ninety-eight patients (15%) had metastatic disease. Four percent of patients with tumors less than 2 cm and 5% of patients with tumors between 2 and 3 cm presented with metastatic disease. Two thousand nine hundred fifty patients (35%) with metastatic disease underwent surgery (radical or partial nephrectomy). Seventy patients (2% of those undergoing surgery) had a partial nephrectomy. Those who underwent partial nephrectomy were 0.49 times less likely to die of RCC than those who underwent radical nephrectomy (95% CI 0.35-0.69, P < 0.001). CONCLUSIONS: Albeit small, the risk of metastases in patients with small kidney tumors is distinct and should be considered in management discussions. Partial nephrectomy, when able to be done, should be utilized in the setting of metastatic disease.

RESUMO

INTRODUCTION: Treatment of the elderly patient with a small renal mass is becoming a common conundrum with scant data available to support treatment decisions. Goals were to assess risk of surgical treatment for renal cell carcinoma (RCC) in the elderly as compared to their younger counterparts. MATERIALS AND METHODS: A prospectively maintained database consisting of all renal tumors between August 2004 and November 2009 was utilized. Patients who underwent extirpative treatment for RCC were divided into groups based on age cutoff of < 75 and ≥ 75 years old. Primary outcome measures were likelihood of partial nephrectomy versus radical nephrectomy, complication rates, and overall and cancer-specific survival. A secondary outcome investigated was renal function. RESULTS: Of 347 patients identified, 273 were < 75, and 74 were ≥ 75 years old. The elderly group was less likely to undergo partial nephrectomy (26% versus 43%, p = 0.045). They also had a higher rate of pT3 disease (20% versus 11%, p = 0.018), worse baseline renal function (46 mL/min/m(2) versus 92 mL/min/m(2), p < 0.001) and a longer length of stay (3.5 days versus 2.2 days, p < 0.001). Complication rates and survival outcomes were similar between the groups. Only Eastern Cooperative Oncology Group (ECOG) ≥ 1 and Charlson index ≥ 2 predicted likelihood of experiencing a complication. CONCLUSIONS: Despite a longer length of stay, renal surgery is safe in selected elderly patients with minimal comorbidity and good functional status. The elderly have reduced baseline renal function indicating nephron sparing should be chosen whenever possible, when surgical intervention is elected.

RESUMO

OBJECTIVE: To understand the impact of cytoreductive nephrectomy on the ability to receive systemic therapy in patients with metastatic renal cell carcinoma. Causes of delayed eligibility and effect on overall survival (OS) were investigated. METHODS: Patients with metastatic renal cell carcinoma who underwent cytoreductive nephrectomy between 2002 and 2010 were identified. Those ineligible to receive systemic therapy>2 months after surgery were considered delayed. Reasons for delay and effect on OS were investigated, including a thorough analysis of surgical morbidity. RESULTS: Of 65 patients identified, 28% experienced delayed eligibility for systemic therapy. Reasons for delay were related to surgery in 33%, disease progression in 56%, and both in 11%. Of the entire cohort, pT4 and sarcomatoid disease predicted poor outcomes with median OS of 9.8 and 7.6 months, respectively. Comparison of the delay vs no delay groups revealed more intraoperative complications (P=.01), a trend toward more high-grade postoperative complications (17% vs 4%, P=.09), and a median OS of 4.8 vs 18.9 months. Controlling for grade and stage, delay and sarcomatoid features independently predicted poor OS (HR, 2.61; P=.01 and HR, 2.25; P=.02, respectively). CONCLUSION: Delay in eligibility for systemic therapy after cytoreductive nephrectomy adversely affects OS and is most commonly caused by disease-related factors, although high-grade complications may contribute. Those with evidence of T4 or sarcomatoid disease features may best be served by systemic therapy followed by cytoreductive nephrectomy only in those exhibiting response.

RESUMO

Objective. Present our experience managing bladder cancer following liver and renal transplantation. Methods. Single institution retrospective review of patients diagnosed with bladder urothelial carcinoma (BUC) following solid organ transplantation between January 1992 and December 2007. Results. Of the 2,925 renal and 2,761 liver transplant recipients reviewed, we identified eleven patients (0.2%) following transplant diagnosed with BUC. Two patients with low grade T1 TCC were managed by TURBT. Three patients with CIS and one patient with T1 low grade BUC were treated by TURBT and adjuvant BCG. All four are alive and free of recurrence at a mean follow-up of 51 ± 22 months. One patient with T1 high grade BUC underwent radical cystectomy and remains disease free with a follow-up of 98 months. Muscle invasive TCC was diagnosed in four patients at a median of 3.6 years following transplantation. Two patients are recurrence free at 24 and 36 months following radical cystectomy. Urinary diversion and palliative XRT were performed in one patient with un-resectable disease. Conclusions. Bladder cancer is uncommon following renal and liver transplantation, but it can be managed successfully with local and/or extirpative therapy. The use of intravesical BCG is possible in select immunosuppressed patients.

RESUMO

BACKGROUND: Black and Hispanic men have a lower prostate cancer (PCa) survival rate than white men. This racial/ethnic survival gap has been explained in part by differences in tumor characteristics, stage at diagnosis, and disparities in receipt of definitive treatment. Another potential contributing factor is racial/ethnic differences in the timely and accurate detection of lymph node metastases. The current study was conducted to examine the association between race/ethnicity and the receipt of pelvic lymph node dissection (PLND) among men with localized/regional PCa. METHODS: Logistic regression was used to estimate the adjusted odds of undergoing PLND among men who were diagnosed during 2000 to 2002 with PCa, who underwent radical prostatectomy or PLND without radical prostatectomy, and who were diagnosed in regions covered by the Surveillance, Epidemiology, and End Results database (n = 40,848). RESULTS: Black men were less likely to undergo PLND than white men (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.84-0.98). When the analysis was stratified by PCa grade, black men with well differentiated PCa (OR, 0.48; 95% CI, 0.27-0.84) and poorly differentiated PCa (OR, 0.73; 95% CI, 0.60-0.89) were less likely to undergo PLND than their white counterparts, but racial differences were not observed among men with moderately differentiated PCa (OR, 0.96; 95% CI, 0.88-1.05). CONCLUSIONS: Among men with poorly differentiated PCa, failure to undergo PLND was associated with worse survival. Racial disparities in the receipt of PLND, especially among men with poorly differentiated PCa, may contribute to racial differences in prostate cancer survival.

RESUMO

OBJECTIVES: Surgical outcomes for a simplified LPN technique using a single-layer closure were reviewed for central and peripheral renal tumors. METHODS: A total of 159 consecutive patients who underwent LPN were identified using a single-institution database. Renal tumors abutting the collecting system or renal sinus were considered central. After tumor excision, the tumor bed was repaired using a single layer closure by passing partially straightened CPX needles beneath the entire cut surface. Pathologic and postoperative outcomes were compared between the central tumor group (CTG) and the peripheral tumor group (PTG). RESULTS: There were 83 and 76 patients in the CTG and PTG, respectively. When compared with the PTG, the CTG had a larger mean tumor size (3.4 vs 2.3 cm, P <.0001) and greater depth of tumor invasion (2.3 vs 1.1 cm, P <.0001). In the CTG, 66 tumors were malignant, and 2 patients had a positive margin. In the PTG, 50 tumors were malignant, and 1 patient had a positive margin. There was no statistically significant difference between the groups in operative times, estimated blood loss, transfusion rates, complications, positive margins, and length of hospital stays. The CTG had a longer warm ischemia time (24 vs 18 minutes, P = .0002), but this did not result in a significant difference in postoperative creatinine clearance (86 vs 87, P = .842). CONCLUSIONS: During LPN, a single-layer closure without bolsters is safe and effective, and early surgical outcomes are similar for central and peripheral tumors.
