RESUMEN

Background: Cardiovascular disease (CVD) incidence is higher in men with prostate cancer (PC) than without. Objectives: We describe the rate and correlates of poor cardiovascular risk factor control among men with PC. Methods: We prospectively characterized 2,811 consecutive men (mean age 68 ± 8 years) with PC from 24 sites in Canada, Israel, Brazil, and Australia. We defined poor overall risk factor control as ≥3 of the following: suboptimal low-density lipoprotein cholesterol (>2 mmol/L if Framingham Risk Score [FRS] ≥15 and ≥3.5 mmol/L if FRS <15), current smoker, physical inactivity (<600 MET min/wk), suboptimal blood pressure (BP) (≥140/90 mm Hg if no other risk factors, systolic BP ≥120 mm Hg if known CVD or FRS ≥15, and ≥130/80 mm Hg if diabetic), and waist:hip ratio >0.9. Results: Among participants (9% with metastatic PC and 23% with pre-existing CVD), 99% had ≥1 uncontrolled cardiovascular risk factor, and 51% had poor overall risk factor control. Not taking a statin (odds ratio [OR]: 2.55; 95% CI: 2.00-3.26), physical frailty (OR: 2.37; 95% CI: 1.51-3.71), need for BP drugs (OR: 2.36; 95% CI: 1.84-3.03), and age (OR per 10-year increase: 1.34; 95% CI: 1.14-1.59) were associated with poor overall risk factor control after adjustment for education, PC characteristics, androgen deprivation therapy, depression, and Eastern Cooperative Oncology Group functional status. Conclusions: Poor control of modifiable cardiovascular risk factors is common in men with PC, highlighting the large gap in care and the need for improved interventions to optimize cardiovascular risk management in this population.

RESUMEN

PURPOSE: Gleason grade (GG) on prostate biopsy is important for risk stratification and clinical decision making. Multiparametric MRI (mpMRI) improved detection of clinically significant disease and some studies suggest that MRI-fusion biopsy combined with systematic biopsy results in fewer upgrades on final surgical pathology. However, the downgrade rate is unclear and there is controversy in the literature. The objectives of this study are to assess the concordance of combination biopsy with final surgical pathology, and furthermore, to specifically determine downgrade rates. MATERIALS AND METHODS: In our institutional mpMRI-ultrasound fusion biopsy database, 173 underwent targeted and systematic biopsy followed by radical prostatectomy (RP). GG on targeted, systematic and combination (targeted and systematic) biopsy were compared with GG on RP. Concordance rates between biopsy types were compared with the McNemar test. Proportion of GG upgrade or downgrade at the time of RP was also evaluated. RESULTS: Surgical pathology was concordant with 44.5% of systematic biopsies, 46.8% of targeted biopsies, and 56.7% of combination biopsies. Combination biopsy significantly overestimated the final GG on RP compared to systematic biopsy (16.8% vs. 8.7% RR 1.93, 95% CI 1.36-2.75, P < 0.001). Downgrade rate from unfavorable to favorable intermediate-risk disease was 46.2%, and from high-risk to intermediate-risk disease was 45.1%. CONCLUSIONS: Combination (targeted and systematic) biopsy is associated with the highest concordance rate between biopsy and RP pathology when compared with systematic or targeted biopsy alone. However, targeting MRI lesions and therefore the higher risk components, may at times overestimate the final surgical pathology which can result in overtreatment of what may truly be less aggressive disease.

RESUMEN

PURPOSE: There exists a growing debate as to whether multiparametric magnetic resonance imaging with fusion transrectal ultrasound guided prostate biopsy alone without a standard template biopsy is sufficient to evaluate patients with suspected prostate cancer. Our objective was to describe our experience with fusion targeted prostate biopsy and assess whether it could obviate the need for concomitant standard 12-core template prostate biopsy. MATERIALS AND METHODS: We retrospectively reviewed our prospectively collected database of patients who underwent fusion transrectal ultrasound guided prostate biopsy. All images and lesions were graded according to the Prostate Imaging Reporting and Data System, version 2. All patients underwent targeted biopsy followed by standard 12-core double sextant biopsy within the same session. Clinically significant prostate cancer was defined as Grade Group 2 or greater prostate cancer. RESULTS: A total of 506 patients were included in analysis. Indications were elevated prostate specific antigen with a previous negative prostate biopsy in 46% of cases, prostate cancer on active surveillance in 35%, elevated prostate specific antigen without a prior prostate biopsy in 15% and an isolated abnormal digital rectal examination in 3%. For standard vs fusion prostate biopsy the overall cancer detection rate was 57.7% vs 54.0% (p=0.12) and the clinically significant prostate cancer detection rate was 24.7% vs 30.8% (p=0.001). Of the 185 patients diagnosed with clinically significant prostate cancer 29 (16%) would have been missed if only targeted fusion prostate biopsy had been performed. CONCLUSIONS: Fusion targeted prostate biopsy is associated with a higher detection rate of clinically significant prostate cancer compared to standard double sextant biopsy. However, standard double sextant biopsy should still be performed as part of the routine fusion targeted prostate biopsy procedure to avoid missing a significant proportion of clinically significant prostate cancer.

RESUMEN

INTRODUCTION: We aimed to assess the contemporary knowledge of human papillomavirus (HPV) and its association with penile cancer in a nationwide cohort from the U.S. METHODS: We used the Health Information National Trends Survey (HINTS), a cross-sectional telephone survey performed in the U.S. initiated by the National Cancer Institute. The most recent iteration, HINTS 4 Cycle 4, was conducted in mail format between August 19 and November 17, 2014. Primary endpoints included knowledge of HPV and its causal relationship to penile cancer. Baseline characteristics included sex, age, education, race and ethnicity, income, residency, personal or family history of cancer, health insurance status, and internet use. Multivariable logistic regression assessed predictors of HPV and penile cancer knowledge. RESULTS: An unweighted sample of 3376 respondents was extracted from the HINTS 4, Cycle 4. Whereas 64.4% of respondents had heard of HPV, only 29.5% of these were aware that it could cause penile cancer. Men were significantly less likely to have heard of HPV than women (odds ratio [OR] 0.32; 95% confidence interval [CI] 0.24-0.43). Older age; African-American, Asian, and "other race"; being married; from a lower education bracket; having a personal cancer history; and those without internet access were significantly less likely to have heard of HPV. None of our examined variables were independent predictors for the knowledge of the association of penile cancer and HPV. CONCLUSIONS: Our analysis of a large, nationally representative survey demonstrates that the majority of the American public is familiar with HPV, but lack a meaningful understanding between this virus and penile cancer. Primary care providers and specialists should be encouraged to intensify counselling about this significant association as a primary preventive measure of this potentially fatal disease.

RESUMEN

PURPOSE: Use of androgen deprivation therapy may increase the risk of cognitive impairment in men with prostate cancer. We performed a systematic review of the risk of overall cognitive impairment as an outcome in men receiving androgen deprivation therapy for prostate cancer. MATERIALS AND METHODS: Studies were identified through PubMed®, MEDLINE®, PsycINFO®, Cochrane Library and Web of Knowledge/Science™. Articles were included if they 1) were published in English, 2) had subjects treated for prostate cancer with androgen deprivation therapy, 3) incorporated longitudinal comparisons and 4) used control groups. In addition, prospective studies were required to assess an established cognitive related end point using International Cognition and Cancer Task Force criteria defining impaired cognitive performance as scoring 1.5 or more standard deviations below published norms on 2 or more tests, or scoring 2.0 or more standard deviations below published norms on at least 1 test. The effect of androgen deprivation therapy on cognitive impairment was pooled using a random effects model. RESULTS: Of 221 abstracts 26 were selected for full text review, and 2 prospective and 4 retrospective studies were analyzed. Androgen deprivation therapy was not associated with overall cognitive impairment when the prospective cohort studies were pooled (OR 1.57, 95% CI 0.50 to 4.92, p = 0.44) with significant heterogeneity between estimates (I2 = 83%). In retrospective data the relative risk of any cognitive impairment, including senile dementia and Alzheimer disease, was increased in men receiving androgen deprivation therapy, although the difference was not statistically significant (HR 1.28, 95% CI 0.93 to 1.76, p = 0.13) with moderate heterogeneity between estimates (I2 = 67%). CONCLUSIONS: Analyses between overall cognitive impairment and use of androgen deprivation therapy defined according to International Cognition and Cancer Task Force criteria in a pooled analysis were inconclusive. In retrospective cohort studies the risk of overall cognitive impairment after androgen deprivation therapy was not significant. Better prospective studies need to be designed for the assessment of this end point.

RESUMEN

OBJECTIVES: Over the past decade, robot-assisted radical cystectomy (RARC) has gained traction as an alternative to the conventional open approach open radical cystectomy (ORC). However, the benefits of RARC over ORC remain unclear. Our objective was to conduct a comparative effectiveness analysis between RARC and ORC using data from the National Cancer Data Base. MATERIALS AND METHODS: Within the National Cancer Data Base, we identified patients with localized muscle-invasive bladder cancer who underwent RC between 2010 and 2013. Patients were stratified according to surgical approach: ORC vs. RARC. Intraoperative endpoints included: the presence of positive surgical margins, the performance of a pelvic lymph node dissection, and number of lymph nodes (LN) removed. Postoperative endpoints included: length of stay (LOS), 30- and 90-day postoperative mortality (POM) rates, 30-day readmission rate, and overall survival (OS). To minimize selection bias, observed differences in baseline characteristics between RARC vs. ORC patients were controlled for using weighted propensity scores. Binary endpoints and OS were assessed using propensity score-adjusted logistic and Cox regression analyses, respectively. POM was assessed using propensity score weighted Kaplan-Meier survival estimates at 30 and 90 days after RC. RESULTS: Of 9,561 patients who underwent RC, 2,048 (21.4%) and 7,513 (78.6%) underwent RARC and ORC, respectively. The use of RARC increased over time, from 16.7% in 2010 to 25.3% in 2013. With regard to intraoperative outcomes, RARC was associated with equivalent rates of positive surgical margins (9.3% vs. 10.7%, odds ratio [OR] = 0.86, 95% CI: 0.72-1.03; P = 0.10), higher rates of pelvic lymph node dissection (96.4% vs. 92.0%, OR = 2.30, 95% CI: 1.67-3.16; P<0.001), higher median LN count (17 vs. 12, P<0.001), higher rates of LN count above the median (56.8% vs. 40.4%, OR = 1.94, 95% CI: 1.55-2.42, P<0.001). With regard to postoperative outcomes, receipt of RARC was associated with a shorter median LOS (7 vs. 8, P<0.001), and lower rates of pLOS (45.0% vs. 54.8%, OR = 0.68, 95% CI: 0.58-0.79; P<0.001). The 30- and 90-day POM rates were 2.8%, 6.7% for ORC, and 1.4%, 4.8% for RARC, respectively (hazard ratio [HR] = 0.48, 95% CI: 0.29-0.80, P = 0.005 and HR = 0.71, 95% CI: 0.54-0.93; P = 0.014). Finally, with a mean follow-up of 26.9 months, on IPTW-adjusted Cox regression analysis, RARC vs. ORC was associated with a benefit in OS (HR = 0.79, 95% CI: 0.71-0.88; P<0.001). CONCLUSIONS: Our large contemporary study found an increased adoption of RARC between 2010 and 2013, with more than 1 out of 4 patients undergoing RARC by the end of the study period. We found that RARC was associated with higher LN counts, shorter LOS, and lower POM. Our results allude to potential benefits of RARC while we wait for more definitive answers from randomized trials.

RESUMEN

INTRODUCTION: Given the ongoing controversies regarding its benefit, prostate specific antigen based prostate cancer screening should be offered with patient preferences in mind. Understanding subsets of men who may or may not choose prostate specific antigen screening and their associated characteristics may allow more efficient care and may identify subsets of patients for whom additional counseling is warranted. METHODS: We analyzed male participants from the 2001 to 2010 cycles of the NHANES (National Health and Nutrition Examination Survey) who were 40 years old or older, and without a history of prostate cancer, recent prostate manipulation or hormone therapy use (8,133). All men were given an opportunity to undergo or refuse prostate specific antigen testing after a standardized explanation about prostate cancer screening from a physician. Univariable and multivariable logistic regressions were conducted after adjusting for survey weights to identify independent sociodemographic and clinical predictors for opting out of prostate specific antigen testing. RESULTS: A total of 7,732 men met the inclusion criteria. Overall 95.64% of the study cohort elected to undergo prostate specific antigen testing. The odds of declining prostate specific antigen testing were significantly higher in men 80 years old or older (OR 1.78, p=0.008), black men (OR 3.23, p <0.001), divorced/separated men (OR 1.66, p=0.002) and men with a preexisting nonprostate malignancy (OR 1.65, p=0.012). CONCLUSIONS: In the setting of the NHANES program, between 2001 and 2010 the majority of men who were offered prostate cancer screening underwent prostate specific antigen testing. Black men, a subgroup subject to more aggressive prostate cancer, were more likely to refuse prostate specific antigen testing.

RESUMEN

BACKGROUND: The use of neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) is supported by results from several randomized control trials, including SWOG-8710. OBJECTIVE: To look at the effectiveness of NAC before RC in current real world practice in the USA. DESIGN, SETTING, AND PARTICIPANTS: We used the National Cancer Data Base (NCDB) to identify patients with nonmetastatic muscle-invasive urothelial carcinoma of the bladder who underwent RC between 2004 and 2012. INTERVENTION: Receipt of NAC before RC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was overall survival (OS). Secondary endpoints were rates of complete pathologic response (pT0), positive pathologic lymph nodes (pN+), and margin status. Using a landmark analysis to adjust for an immortal-time bias, OS comparison was performed using Cox regression analysis. Furthermore, logistic regression models examining secondary outcomes were fitted. To adjust for potential selection bias, propensity score-weighted analyses were performed. RESULTS AND LIMITATIONS: Of 8732 patients who underwent RC, 1619 (19%) received NAC. Following propensity score adjustment, receipt of NAC was not associated with an OS benefit (hazard ratio 0.97; p=0.591). On secondary outcome analysis, higher pT0 rates (odds ratio 5.03; p<0.001) were recorded among patients who received NAC, although rates of pT0 were lower than for patients treated with NAC within the SWOG-8710 trial (13% vs 38%). Limitations include the retrospective design and limited details available regarding type of chemotherapy. CONCLUSIONS: Important baseline differences between patients from the SWOG-8710 trial and those in general urologic practice exist. After adjusting for immortal-time bias, we did not find a clear survival advantage of NAC before RC when compared to RC alone in current general urology practice in the USA. PATIENT SUMMARY: The benefit of chemotherapy before radical cystectomy is supported by few randomized control trials. In this study, using a large national data set from the USA we found that preoperative chemotherapy is not associated with a survival benefit in all patients in general urology practice. Hence, better selection criteria are needed to determine who will benefit the most from chemotherapy before radical cystectomy.

RESUMEN

Purpose There is limited evidence to support the use of adjuvant chemotherapy (AC) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Against this backdrop, we hypothesized that such treatment is associated with overall survival (OS) benefit in patients with locally advanced and/or positive regional lymph node disease. Patients and Methods Within the National Cancer Database (2004 to 2012), we identified 3,253 individuals who received AC or observation after RNU for pT3/T4 and/or pN+ UTUC. Inverse probability of treatment weighting (IPTW) -adjusted Kaplan-Meier curves and Cox proportional hazards regression analyses were used to compare OS of patients in the two treatment groups. In addition, we performed exploratory analyses of treatment effect according to age, gender, Charlson comorbidity index, pathologic stage (pT3/T4N0, pT3/T4Nx and pTanyN+), and surgical margin status. Results Overall, 762 (23.42%) and 2,491 (76.58%) patients with pT3/T4 and/or pN+ UTUC received AC and observation, respectively, after RNU. IPTW-adjusted Kaplan-Meier curves showed that median OS was significantly longer for AC versus observation (47.41 [interquartile range,19.88 to 112.39] v 35.78 [interquartile range, 14.09 to 99.22] months; P < .001). The 5-year IPTW-adjusted rates of OS for AC versus observation were 43.90% and 35.85%, respectively. In IPTW-adjusted Cox proportional hazards regression analysis, AC was associated with a significant OS benefit (hazard ratio, 0.77 [95% CI, 0.68 to 0.88]; P < .001). This benefit was consistent across all subgroups examined (all P < .05), and no significant heterogeneity of treatment effect was observed (all Pinteraction > .05). Conclusion We report an OS benefit in patients who received AC versus observation after RNU for pT3/T4 and/or pN+ UTUC. Although our results are limited by the usual biases related to the observational study design, we believe that the present findings should be considered when advising post-RNU management of advanced UTUC, pending level I evidence.

RESUMEN

INTRODUCTION: To evaluate perioperative outcomes related to resident involvement (RI) in a large and prospectively collected multi-institutional database of patients undergoing orchiectomy for testicular cancer. MATERIALS AND METHODS: Using current procedural terminology and ICD-9 codes, information about patients with testicular cancer were abstracted from the American College of Surgeons National Surgical Quality Improvement Program database (2006-2013). Multivariable analyses evaluated the impact of RI on outcomes after orchiectomy. Prolonged operative time (pOT) and prolonged length of stay were defined by the 75th percentile (59 min) and postoperative inpatient stay ≥2 days, respectively. RESULTS: Overall, 267 patients underwent orchiectomy either with (38.6%) or without (61.4%) RI. In all, 89.1% of patients underwent an outpatient procedure. The median body mass index was 26.8 and baseline characteristics between the 2 groups were similar. Overall complications, re-intervention, and bleeding-related complication rates were 2.6, 0.7, and 0.4%, respectively. Although there was no difference in terms of overall complications between the groups (3.9 vs. 1.8%; p = 0.44), RI resulted in pOT (32 vs. 19.5%; p = 0.028). In multivariable analyses, RI predicted pOT (OR 1.89, 95% CI 1.06-3.37; p = 0.031), without association with prolonged length of stay and overall complications. CONCLUSIONS: RI during orchiectomy for testicular cancer does not undermine patient safety at the cost of pOT.

RESUMEN

Purpose Evidence from studies of other malignancies has indicated that aggressive local treatment (LT), even in the presence of metastatic disease, is beneficial. Against a backdrop of stagnant mortality rates for metastatic urothelial carcinoma of the bladder (mUCB) at presentation, we hypothesized that high-intensity LT of primary tumor burden, defined as the receipt of radical cystectomy or ≥ 50 Gy of radiation therapy delivered to the bladder, affects overall survival (OS). Patients and Methods We identified 3,753 patients within the National Cancer Data Base who received multiagent systemic chemotherapy combined with high-intensity versus conservative LT for primary mUCB. Patients who received no LT, transurethral resection of the bladder tumor alone, or < 50 Gy of radiation therapy delivered to the bladder were included in the conservative LT group. Inverse probability of treatment weighting (IPTW) -adjusted Kaplan-Meier curves and Cox regression analyses were used to compare OS of patients who received high-intensity versus conservative LT. Results Overall, 297 (7.91%) and 3,456 (92.09%) patients with mUCB received high-intensity and conservative LT, respectively. IPTW-adjusted Kaplan-Meier curves showed that median OS was significantly longer in the high-intensity LT group than in the conservative LT group (14.92 [interquartile range, 9.82 to 30.72] v 9.95 [interquartile range, 5.29 to 17.08] months, respectively; P < .001). Furthermore, in IPTW-adjusted Cox regression analysis, high-intensity LT was associated with a significant OS benefit (hazard ratio, 0.56; 95% CI, 0.48 to 0.65; P < .001). Conclusion We report an OS benefit for individuals with mUCB treated with high-intensity versus conservative LT. Although the findings are subject to the usual biases related to the observational study design, these preliminary data warrant further consideration in randomized controlled trials, particularly given the poor prognosis associated with mUCB.

RESUMEN

PURPOSE: The role of cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) has become unclear since the introduction of targeted therapies (TT). We sought to evaluate contemporary utilization rates of CN and to examine the survival benefit of CN compared with non-CN patients treated with TT. METHODS: We used the National Cancer Data Base to identify patients with clinical mRCC treated with TT between 2006 and 2013. The intervention of interest was CN. Multivariable logistic regression predicting receipt of CN was performed. Overall survival (OS) was examined using Cox regression models and incremental survival analyses were performed. Sensitivity analyses using propensity scores were conducted. RESULTS: Of 15,390 patients treated with TT, 5,374 (35%) underwent CN between 2006 and 2013. Patients who were younger, privately insured, treated at an academic center, and had lower tumor stage and cN0 disease were more likely to undergo CN. The median OS of CN versus non-CN patients was 17.1 (95% CI, 16.3 to 18.0 months) versus 7.7 months (95% CI, 7.4 to 7.9 months; P < .001). In sensitivity analyses using propensity scores adjustment in addition to other available covariates, CN patients had a lower risk of any death (hazard ratio, 0.45; 95% CI, 0.40 to 0.50; P < .001). The survival benefit of CN was +0.7 and +3.6 months in patients who survived ≤ 6 and ≤ 24 months, respectively, versus no CN. CONCLUSION: CN is performed in three of 10 patients with mRCC who are receiving TT. Several patient and sociodemographic characteristics were associated with receipt of CN. When feasible, CN may offer an OS benefit when combined with TT.

RESUMEN

INTRODUCTION: We compare the complication rates and length of stay (LOS) of laser transurethral resection of the prostate (L-TURP) versus electrocautery transurethral resection of the prostate (E-TURP) in a population-based cohort. L-TURP has shown enhanced intraoperative safety and equivalent efficacy relative to E-TURP in several high volume centres. METHODS: Relying on the Florida Datafile as part of the Healthcare Cost and Utilization Project State Inpatient Databases (SID) between 2006 and 2008, we identified 8066 men with benign prostate hyperplasia who underwent L-TURP or E-TURP. Chi-square and Mann-Whitney tests were used to compare baseline characteristics. A multivariable linear regression model was used to analyze the effect of L-TURP versus E-TURP on complication rates and LOS. RESULTS: Overall complication rates did not differ significantly for L-TURP compared to E-TURP in univariable (8.8 vs. 7.4%, p = 0.1) and multivariable analyses (odds ratio [OR]: 1.06, confidence interval [CI]: 0.85-1.32, p = 0.6). Individuals undergoing E-TURP were less likely to experience a LOS in excess of 1 day (46.2 vs. 59.7%, p < 0.001). A lower risk to experience a LOS in excess of 1 day was confirmed for patients undergoing L-TURP after a multivariable linear regression model (OR: 0.37, CI: 0.23-0.58, p < 0.001), but not for a LOS in excess of 2 days (OR: 0.96, CI: 0.83-1.10, p = 0.2). CONCLUSIONS: Patient characteristics and perioperative safety were similar for L-TURP and E-TURP patients. However, LOS patterns demonstrated a modest benefit for L-TURP compared to E-TURP patients.

RESUMEN

OBJECTIVES: Local tumor destruction (LTD) is a recommended therapy alternative for localized T1 renal cell carcinoma for patients who are unfit for surgery. We examined patterns of use and complication rates of LTD in a large population-based cohort. MATERIALS AND METHODS: Overall, data for 5,285 patients undergoing LTD for renal cell carcinoma were extracted from the Nationwide Inpatient Sample database from 2006 to 2010. We assessed patient and hospital characteristics, as well as postoperative complications, using International Classification of Diseases, Ninth Revision codes. The effect of patient and hospital characteristics on peri-interventional complications (overall or specific) was tested using univariable or multivariable logistic regression models. RESULTS: Most patients were male (61.2%), aged 71 to 80 years (34.9%), and had 3 or more comorbidities (30.6%). Most LTDs were performed at urban (93.5%), teaching (57.7%), and low-volume (75.7%) hospitals. Overall complications were recorded in 15.4% of patients. In multivariable analyses adjusted for clustering, overall complications occurred more frequently in older, sicker patients who were treated at low-volume hospitals (all P<0.05). Similar results were recorded when each complication category was addressed individually. CONCLUSIONS: In the current population-based cohort, complications of LTD occurred in 1 of 6 patients and were more frequent in individuals with advanced age or multiple comorbidities, or both, especially if LTDs were performed at lower-volume hospitals.

RESUMEN

BACKGROUND: The gold standard for staging the local extension (T stage) and lymph node (LN) status (N stage) of esophageal cancer is endoscopic ultrasonography (EUS). When biopsy of the peritumoral LNs is performed using EUS, there is a risk of specimen contamination secondary to piercing the primary tumor; this shortcoming can be circumvented with endobronchial ultrasonography (EBUS). Moreover, EBUS allows for biopsy of LN stations not accessible with EUS. METHODS: The study consisted of a prospective clinical trial. Fifty-two consecutive patients with potentially resectable esophageal cancer referred for endoscopic staging were prospectively enrolled. Radial and convex EUS followed by convex EBUS were performed during a single staging procedure. The LNs not accessible by EUS were biopsied using EBUS. Results of the EBUS procedure were compared to those of EUS in terms of the addition of staging information, upstaging, and confirmation of stage. RESULTS: The combined EBUS-EUS procedure was performed in 42 patients. Ten patients were excluded. In all, 54 LNs were biopsied under EUS guidance and 48 LNs were biopsied under EBUS guidance. The EUS results were positive for metastatic esophageal cancer in 29 LNs (54%), and EBUS was positive in 10 LNs (21%). The addition of EBUS to EUS in the staging of esophageal cancer led to nodal and patient upstaging in 5 patients (12%) and confirmed the EUS stage with additional negative or positive LN sampling in 29 patients (69%). Positive EBUS that led to upstaging (5 patients) changed the treatment plan from potentially resectable to palliative. There was no morbidity related to EBUS. CONCLUSIONS: A combined EBUS-EUS staging procedure improves precision in staging, leads to upstaging, and can change the treatment plan in patients with esophageal cancer.

RESUMEN

Our objective was to test whether Fuhrman grade [corrected] (FG) is applicable in the context of chromophobe renal cell carcinoma patients treated with partial and radical nephrectomy. Patients (n=1862) with chromophobe renal cell carcinoma treated with partial and radical nephrectomy were identified within the Surveillance, Epidemiology, and End Results (1988-2008). Univariable and multivariable Cox regression analyses were fitted to predict cancer-specific mortality. Discriminant properties were assessed for the conventional four-tiered FG scheme. Additionally, discrimination of the three-tiered FG scheme (1-2 vs 3 vs 4) and the two-tiered FG scheme (1-2 vs 3-4) was also assessed. The statistical significance of the differences in accuracy estimates was compared using the Mantel-Haenszel test. A total of 65 of the 1862 died of the disease. The overall 5-year cancer-specific mortality-free survival rate was 94.8% (95% confidence interval: 93.5-96.2). In univariable analyses, none of the FG strata were significantly associated with cancer-specific mortality. Furthermore, FG was less informative (63%) than tumor size (72%) and tumor stage (69%), using measures of discrimination in univariable analyses. After accounting for all covariates, prediction of 5-year cancer-specific mortality was 79.0% vs 80.3% accurate, respectively, with vs without the consideration of FG (P=0.01). Similar discrimination estimates were obtained for the modified three-tiered FG scheme (78.5%; P=0.009) and the modified two-tiered FG scheme (79.5%; P=0.02). In conclusion, FG is not an informative predictor of prognosis, defined as cancer-specific mortality, after partial and radical nephrectomy for chromophobe renal cell carcinoma patients.
