Genomics in active surveillance and post-prostatectomy patients: A review of when and how to use effectively.

PURPOSE OF REVIEW: Prostate cancer (PCa) represents a significant health burden globally, ranking as the most diagnosed cancer among men and a leading cause of cancer-related mortality. Conventional treatment methods such as radiation therapy or radical prostatectomy have significant side effects which often impact quality of life. As our understanding of the natural history and progression of PCa has evolved, so has the evolution of management options. RECENT FINDINGS: Active surveillance (AS) has become an increasingly favored approach to the management of very low, low, and properly selected favorable intermediate risk PCa. AS permits ongoing observation and postpones intervention until definitive treatment is required. There are, however, challenges with selecting patients for AS, which further emphasizes the need for more precise tools to better risk stratify patients and choose candidates more accurately. Tissue-based biomarkers, such as ProMark, Prolaris, GPS (formerly Oncotype DX), and Decipher, are valuable because they improve the accuracy of patient selection for AS and offer important information on the prognosis and severity of disease. By enabling patients to be categorized according to their risk profiles, these biomarkers help physicians and patients make better informed treatment choices and lower the possibility of overtreatment. Even with their potential, further standardization and validation of these biomarkers is required to guarantee their broad clinical utility. Active surveillance has emerged as a preferred strategy for managing low-risk prostate cancer, and tissue-based biomarkers play a crucial role in refining patient selection and risk stratification. Standardization and validation of these biomarkers are essential to ensure their widespread clinical use and optimize patient outcomes.

Diversity, Equity, and Inclusion: Advancing Curricular Development and Recruitment.

PURPOSE OF REVIEW: Currently, the increasing diversity of our society is poorly reflected in the urology workforce. In this review, we sought to address this disparity by highlighting key components involved in forming an academic urology department and training program that is focused on diversity, equity, and inclusion (DEI) as well as recruitment and retention of underrepresented in medicine (URiM) trainees and faculty. RECENT FINDINGS: We identified obstacles and provided approaches to enhance the ability of a department in creating a DEI-based curriculum and recruitment strategy with a key focus on understanding and addressing unconscious biases and microaggressions in the workplace. Substantive changes in the level of diversity within the urologic community can be made through the organization of a structured approach to increasing DEI. It starts with a commitment from each department to form achievable goals surrounding early mentorship of URiM students and trainees, an inclusive curriculum that is rooted in DEI, and targeted benchmarks for recruitment and retention of diverse staff.

The value of residency program characteristics changes throughout urology training.

INTRODUCTION: The purpose of this study was to determine which characteristics of urology residency programs are most highly valued by medical students and residents, and how these change during training. MATERIALS AND METHODS: We distributed a survey to urology residents and medical students interested in urology via program director email and social media. The survey collected demographic data, future career plans, and asked respondents to rank the relative importance of six categories of residency program characteristics and specific characteristics within each category. RESULTS: Among the six categories of residency characteristics, resident experience was ranked most important by both medical students and residents, followed by geography and clinical experience which were tied. Medical students ranked clinic experience and formal mentorship with greater importance while residents placed higher value on the active role of clinical faculty and help from advanced practice providers. Trainees planning for an academic career ranked research experiences and resident diversity as more important than those entering private practice. CONCLUSIONS: Residents and medical students mostly agreed on the relative importance of residency program characteristics. The differences observed suggest that as trainees gain experience they place greater importance on informal relationships with faculty and value characteristics that enhance surgical training such as support from advanced practice providers and less time in clinic. These findings may guide programs on what information to include on their websites and presentations.

Definitive treatment choice among Black immigrants with prostate cancer: Analysis of patient surveys distributed at a single safety-net institution.

BACKGROUND: Large-scale prostate cancer (PCa) database reviews have found a consistent discrepancy in the mortality rate in Black patients compared to their White counterparts. Furthermore, differences in PCa treatment and outcomes among Black men of different ethnic origins have also been identified. Due to the heterogeneity of PCa-impacted communities and the unclear impact of patient immigration status on treatment outcomes, we sought to determine the demographic factors associated with treatment choice for definitive treatment of PCa in our single institution's patient population of Black immigrants. METHODS: We distributed surveys to all patients in the Kings County Hospital Center urologic oncology clinic from February 2019 to February 2020 and collected relevant health information via EMR. The survey collected demographic information regarding age, education, health insurance, employment status, socioeconomic status, country of birth, and years living in the United States (US). RESULTS: Out of the 253 patients surveyed, the majority of patients surveyed were Black and foreign born. There were no significant differences in demographic data between US-born and foreign-born patients except number of years living in the United States. In the intermediate risk group, patients living in the United States for <10 years chose surgery significantly more often than US-born patients (90.9% vs. 50.0%, p = 0.036). On multivariate analysis, patients that chose surgery were more likely to be older when diagnosed (odds ratio [OR] = 1.21) and less likely to be born in the United States than in African or Caribbean countries (OR = 0.054). CONCLUSIONS: In our study of a majority-Black population, we found that patients born in the United States were less likely than their foreign counterparts to opt for surgery, as previous studies have shown. The choice of definitive treatment modality for Black men with intermediate risk PCa was found to be influenced by age at diagnosis and immigration status.

Determinants of neoadjuvant chemotherapy for urothelial muscle-invasive bladder cancer: Does location matter?

INTRODUCTION: Bladder cancer care has been increasingly concentrated in high-volume metropolitan medical centres (ie, "regionalisation" of care). We aimed to assess the potential role of geographic factors, including facility region and distance to treatment centre, as determinants of neoadjuvant chemotherapy (NAC) delivery in patients with non-metastatic urothelial muscle-invasive bladder cancer (MIBC) using nationally representative data from the United States. METHODS: We queried the National Cancer Database to identify patients with cT2-cT4a, N0M0 urothelial MIBC who underwent radical cystectomy (RC) from 2006 to 2015. Patients who received radiation therapy, single-agent chemotherapy, adjuvant chemotherapy or systemic therapies other than multi-agent chemotherapy were excluded. Multivariate logistic regression analysis was performed to identify independent predictors of receiving NAC. RESULTS: A total of 5986 patients met the criteria for inclusion, of whom 1788 (29.9%) received NAC and 4108 received RC alone. Younger age, increased Charlson-Deyo score, increased cT stage, increased annual income, increased distance from cancer treatment centre, treatment at an Academic Research Program or Integrated Network Cancer Program and a later year of diagnosis were independently predictive of NAC receipt. Older age, Medicare insurance and treatment in the East South Central or West South Central regions were independently associated with decreased odds of NAC receipt. CONCLUSIONS: Distance to treatment centre and United States geographic region were found to affect the likelihood of NAC receipt independently of other established predictors of success in this quality-of-care metric. Access to transportation and related resources merits consideration as additional pertinent social determinants of health in bladder cancer care.

Assessing the role of race in pathological upstaging of renal cell carcinoma: Results from the National Cancer Database.

PURPOSE: Pathologic upstaging in renal cell carcinoma (RCC) is common and confers a significant risk of poor surgical and survival outcomes. Preoperative predictors of upstaging are of great clinical relevance but empirical evidence specific to racial minorities remains scarce. METHODS: National Cancer Database (NCDB) analysis of T3a-specific upstaging among White, African-American, Hispanic and Asian Pacific Islander (API) patients with AJCC cT1N0M0 RCC who underwent partial or radical nephrectomy between 2010 and 2015. Independent preoperative predictors of tumour upstaging were identified using multivariate logistic regression analyses. RESULTS: A total of 81 002 patients met the criteria for inclusion (5.6% T3a-specific upstaging). Increased age, increased Charlson-Deyo comorbidity index, clinical stages cT1b and unspecified cT1, and increased Fuhrman nuclear grade were identified as independent risk factors for upstaging. Independent protective factors for upstaging were younger age, female sex, African-American race and papillary, chromophobe, and unspecified RCC histologic subtypes. Significant risk factors and protective factors within individual racial subgroups were highly consistent with those observed in the overall study sample. All independent factors identified on race-specific subgroup analyses were significant in the same direction relative to the overall study sample. Variables found to be non-significant in the overall study sample remained non-significant across all racial subgroup analyses. CONCLUSION: The present study of nationally representative data found no clinically significant differences in upstaging risk across individual racial subgroups relative to the overall study sample. Preoperative factors that can be used to predict pT3a-specific tumour upstaging in CT1N0M0 RCC likely persist across different racial groups.

Racial Differences in Incident Genitourinary Cancer Cases Captured in the National Cancer Database.

Background and Objectives: The National Cancer Database (NCDB) captures nearly 70% of all new cancer diagnoses in the United States, but there exists significant variation in this capture rate based on primary tumor location and other patient demographic factors. Prostate cancer has the lowest coverage rate of all major cancers, and other genitourinary malignancies likewise fall below the average NCDB case coverage rate. We aimed to explore NCDB coverage rates for patients with genitourinary cancers as a function of race. Materials and Methods: We compared the incidence of cancer cases in the NCDB with contemporary United States Cancer Statistics data. Results: Across all malignancies, American Indian/Alaskan Natives subjects demonstrated the lowest capture rates, and Asian/Pacific Islander subjects exhibited the second-lowest capture rates. Between White and Black subjects, capture rates were significantly higher for White subjects overall and for prostate cancer and kidney cancer in White males, but significantly higher for bladder cancer in Black versus White females. No significant differences were observed in coverage rates for kidney cancer in females, bladder cancer in males, penile cancer, or testicular cancer in White versus Black patients. Conclusions: Differential access to Commission on Cancer-accredited treatment facilities for racial minorities with genitourinary cancer constitutes a unique avenue for health equity research.

Expression of Small Noncoding RNAs in Urinary Exosomes Classifies Prostate Cancer into Indolent and Aggressive Disease.

PURPOSE: This is the first report of the development and performance of a platform that interrogates small noncoding RNAs (sncRNA) isolated from urinary exosomes. The Sentinel™ PCa Test classifies patients with prostate cancer from subjects with no evidence of prostate cancer, the miR Sentinel CS Test stratifies patients with prostate cancer between those with low risk prostate cancer (Grade Group 1) from those with intermediate and high risk disease (Grade Group 2-5), and the miR Sentinel HG Test stratifies patients with prostate cancer between those with low and favorable intermediate risk prostate cancer (Grade Group 1 or 2) and those with high risk (Grade Group 3-5) disease. MATERIALS AND METHODS: sncRNAs were extracted from urinary exosomes of 235 participants and interrogated on miR 4.0 microarrays. Using proprietary selection and classification algorithms, informative sncRNAs were selected to customize an interrogation OpenArray™ platform that forms the basis of the tests. The tests were validated using a case-control sample of 1,436 subjects. RESULTS: The performance of the miR Sentinel PCa Test demonstrated a sensitivity of 94% and specificity of 92%. The Sentinel CS Test demonstrated a sensitivity of 93% and specificity of 90% for prediction of the presence of Grade Group 2 or greater cancer, and the Sentinel HG Test demonstrated a sensitivity of 94% and specificity of 96% for the prediction of the presence of Grade Group 3 or greater cancer. CONCLUSIONS: The Sentinel PCa, CS and HG Tests demonstrated high levels of sensitivity and specificity, highlighting the utility of interrogation of urinary exosomal sncRNAs for noninvasively diagnosing and classifying prostate cancer with high precision.

Rates of clinically significant prostate cancer in African Americans increased significantly following the 2012 US Preventative Services Task Force recommendation against prostate specific antigen screening: A Single Institution Retrospective Study.

PURPOSE: We determined the impact of the 2012 US Preventative Services Task Force recommendation against prostate specific antigen screening on detection rates and biopsy patterns in African American and Caucasian patients. MATERIALS AND METHODS: Demographics, PSA, transrectal ultrasonography volume and pathologic data were collected on patients who underwent their first ultrasound-guided prostate biopsy between January 2007 and June 2018 at a New York City Veteran Affairs Hospital. RESULTS: 609 biopsies were analysed preguideline (113 per year), and 487 were analysed postguideline (81 per year). There was no significant difference in the detection rates of low, intermediate or high grade PCa in Caucasians. In contrast, African Americans were significantly more likely to be diagnosed with PCa in the postguideline group (56% pre vs 66% post, P = .016), and significantly more likely to be diagnosed with intermediate-high grade PCa (38% pre vs 47% post, P = .038). Before the 2012 USPSTF recommendation, African American and Caucasian patients undergoing their first biopsy were equally likely to be diagnosed with high-grade PCa (11% AA vs 11% CA). After the 2012 decision, we found that African Americans were 50% more likely than Caucasians to be diagnosed with high-grade PCa on first biopsy (10% AA vs 15% CA, P = .008). CONCLUSIONS: In the 6 years following the 2012 USPSTF recommendation, detection rates of intermediate-high risk disease remained unchanged for Caucasian patients but have increased significantly for African Americans. The results of our study strongly support the role of routine PSA screening, particularly in higher risk patients such as African Americans.

Timing of blood transfusion and oncologic outcomes in patients treated with radical nephroureterectomy for upper tract urothelial carcinoma.

PURPOSE: To evaluate the impact of timing of blood transfusion in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). METHODS: Outcomes of consecutive patients with UTUC treated with RNU were analyzed. Clinicopathologic factors were compared using Fisher's exact test or the Wilcoxon rank-sum test between patients who received any transfusion and no transfusion, and between patients receiving intraoperative transfusion only and patients receiving no transfusion. Cancer-specific and overall survival were estimated and multivariable analyses were performed to assess the impact of timing of transfusion on clinical outcomes. RESULTS: Among 402 patients included in this study, 71 (17.6%) patients received a transfusion at any point and 27 (6.7%) patients received an intraoperative blood transfusion. Transfusion at any time, patient comorbidity, high grade, advanced stage, positive surgical margins, low preoperative hemoglobin, longer operative duration, and increased blood loss were significantly associated with cancer-specific survival (DSS) on univariable analysis (HR 1.85, 95% CI 1.20-2.85, p < 0.005). In the multivariable analysis, transfusion at any point was not a prognostic factor (HR 1.00, 95% CI 0.60-1.68, p = 0.99). When examining intraoperatively transfusion only, transfusion was significantly associated with DSS (HR 1.91, 95% CI 1.01-3.59, p = 0.045) but no longer significant in multivariable analysis (HR 0.72, 95% CI 0.32-1.65, p = 0.440). CONCLUSIONS: Our study indicates that the administration of blood transfusion either intraoperatively or postoperatively is not associated with clinical or oncological outcomes in patients with upper tract urothelial carcinoma when adjusted for other factors in multivariable analysis. Further study is required.

Changes observed in prostate biopsy practices in an inner city hospital with a high risk patient population following the 2012 uspstf psa screening recommendations.

INTRODUCTION: We compared characteristics of patients undergoing prostate biopsy in a high-risk inner city population before and after the 2012 USPSTF recommendation against PSA based prostate cancer screening to determine its effect on prostate biopsy practices. MATERIALS AND METHODS: This was a retrospective study including patients who received biopsies after an abnormal PSA measurement from October 2008-December 2015. Patients with previously diagnosed prostate cancer were excluded. Chi-square tests of independence, two sample t-tests, Mann-Whitney U tests, and Fisher's exact tests were performed. RESULTS: There were 202 and 208 patients in the pre-USPSTF and post-USPSTF recommendation cohorts, respectively. The post-USPSTF cohort had higher median PSA (7.8 versus 7.1ng/mL, p=0.05), greater proportion of patients who were black (96.6% versus 90.5%, p=0.01), and greater percentage of biopsy cores positive for disease (58% versus 29.5%, p<0.001). Multivariable analysis supported that the increase in PSA was independent of the increase in the proportion of patients who were black. The proportion of patients who were classified as D'Amico intermediate and high-risk disease increased in the post-USPSTF cohort and approached statistical significance (70.1% versus 58.8%, p=0.12). CONCLUSIONS: Our study suggests that the USPSTF recommendations may have led to na increase in pre-biopsy PSA as well as greater volume of disease. Also, a greater proportion of patients were being classified with intermediate or high risk disease. While the clinical significance of these findings is unknown, what the data suggests is somewhat troubling. Future research should further examine these changes in a larger cohort as well as resultant long-term outcomes.

Association between lymph node yield and survival among patients undergoing radical nephroureterectomy for urothelial carcinoma of the upper tract.

BACKGROUND: Prior studies examining the value of lymph node (LN) dissection (LND) in patients with urothelial carcinoma of the upper urinary tract (UTUC) have produced conflicting results. The objective of the current study was to assess the relationship between LN yield and survival among patients undergoing radical nephroureterectomy (RNU). METHODS: The National Cancer Data Base was used to identify patients with non-metastatic UTUC who were treated with RNU between 2004 and 2012. The association between LN yield and overall survival (OS) was assessed using Cox proportional hazards regression, with adjustment for patient, tumor, and facility characteristics. RESULTS: Of the 14,472 patients, 2926 (20%) underwent LND. The median yield was 2 LNs (interquartile range 1-6 LNs). Among the entire cohort and the LN-negative (pN0) subgroup, a higher LN yield was associated with lower all-cause mortality (multivariable hazard ratio [HR] 0.94 per 5 LNs removed, 95% confidence interval [95% CI] 0.89-1.00 [P = .034] for the entire cohort and HR 0.86, 95% CI 0.79-0.94 [P = .001] for the pN0 subgroup). Among patients with positive LNs (pN+), there was no association noted between LN yield and OS; however, positive and negative LN counts were found to be independent predictors of OS (HR 1.27 per 5 positive LNs, 95% CI 1.16-1.39 [P<.001] and HR 0.90 per 5 negative LNs, 95% CI 0.82-1.00 [P = .049]). CONCLUSIONS: In this large, contemporary cohort of patients with UTUC, LND was found to be used infrequently despite evidence that a higher LN yield is associated with lower all-cause mortality.

Validation and genomic interrogation of the MET variant rs11762213 as a predictor of adverse outcomes in clear cell renal cell carcinoma.

BACKGROUND: The exonic single-nucleotide variant rs11762213 located in the MET oncogene has recently been identified as a prognostic marker in clear cell renal cell carcinoma (ccRCC). This finding was validated with The Cancer Genome Atlas (TCGA) cohort, and the biologic implications were explored. METHODS: The genotype status for rs11762213 was available for 272 patients. Paired tumor-normal data, genomic data, and clinical information were acquired from ccRCC TCGA data sets. Cancer-specific survival (CSS) was analyzed with the competing risk method, and Cox proportional hazards regression was used for the analysis of the time to recurrence (TTR). Multivariate competing risk models were fitted to adjust for the validated Mayo Clinic Stage, Size, Grade, and Necrosis (SSIGN) score. RESULTS: The variant allele of rs11762213 was detected in 10.3% of the cohort. After adjustments for the SSIGN score, the risk allele remained a significant predictor for adverse CSS (hazard ratio [HR], 3.88; 95% confidence interval [CI], 1.99-7.56; P < .0001) and for TTR (OR, 2.97; 95% CI, 1.43-6.2; P = .003). The mapping of rs11762213 to regulatory regions within the genome suggested that it might affect a DNA enhancer region. RNA and protein sequencing data for MET did not reveal differences in steady-state expression with stratification by risk allele. CONCLUSIONS: The exonic MET variant rs11762213 is an independent predictor of adverse CSS and TTR in ccRCC and should be integrated into clinical practice for prognostic stratification. Genomic analysis suggests that the single-nucleotide polymorphism may affect an enhancer region located in the coding region of MET. Further biological mechanistic interrogation is currently underway.

Contemporary evaluation and management of renal trauma.

INTRODUCTION: Renal trauma occurs in approximately 1%-5% of all trauma cases. Improvements in imaging and management over the last two decades have caused a shift in the treatment of this clinical condition. MATERIALS AND METHODS: A systematic search of PubMed was performed to identify relevant and contemporary articles that referred to the management and evaluation of renal trauma. RESULTS: Computed tomography remains a mainstay of radiological evaluation in hemodynamically stable patients. There is a growing body of literature showing that conservative, non-operative management of renal trauma is safe, even for Grade IV-V renal injuries. If surgical exploration is planned due to other injuries, a conservative approach to the kidney can often be utilized. Follow up imaging may be warranted in certain circumstances. Urinoma, delayed bleeding, and hypertension are complications that require follow up. CONCLUSION: Appropriate imaging and conservative approaches are a mainstay of current renal trauma management.

Pathological Stage T3a Significantly Increases Disease Recurrence across All Tumor Sizes in Renal Cell Carcinoma.

PURPOSE: Tumor size and stage are important prognostic parameters in renal cell carcinoma. While pathological stage T1 and T2 are defined by size alone, the presence of certain intrinsic features can up stage a tumor to pathological stage T3a regardless of size. We investigate the effect of pathological tumor stage on the relationship between tumor size and risk of disease recurrence. MATERIALS AND METHODS: Data were reviewed on patients who underwent nephrectomy at our institution between 2006 and 2013 to identify all those with pathological stage T1, T2 and T3a tumors. A proportional hazards Cox model was built with time to recurrence as outcome, and pathological stage and tumor size as covariates. An interaction term for stage and tumor size was included. RESULTS: The final cohort included 1,809 patients. On multivariable analysis, when adjusted for tumor size, patients with pT3a tumors had a greater risk of tumor recurrence compared to those with pT1/T2 tumors (HR 3.70; 95% CI 2.31, 5.92; p <0.0001). The risk of disease recurrence increased more rapidly as tumor size increased only with the presence of perinephric fat invasion (p=0.006). CONCLUSIONS: Using the AJCC 2010 staging criteria we validated pathological stage T3a as a poor prognostic factor in renal cell carcinoma regardless of tumor size. Our results also demonstrated an increased rate of risk of recurrence with perinephric fat invasion. Given this increased risk of recurrence, even in tumors less than 4 cm, closer surveillance is warranted in such cases and the role of perinephric involvement necessitates further investigation.

Non-squamous cell carcinoma of the penis: single-center, 15-year experience.

PURPOSE: Penile cancer is a rare malignancy with less than 5 % being non-squamous cell carcinoma (SCC) primary malignancies. We report our 15-year experience of treating non-SCC penile cancer at a tertiary care cancer center. METHODS: We identified 12 patients with non-SCC of the penis from 1996 to 2012. Demographic and clinical data were abstracted, including histological type, surgical treatment, adjuvant therapy, and clinical course. RESULTS: Five patients had sarcoma (three leiomyosarcoma, one spindle cell carcinoma, and one epithelioid sarcoma), four had melanoma, two had extramammary Paget's disease (EPD), and one had sebaceous carcinoma. Median follow-up was 37.5 months (mean 45.8 months). Tumor staging for melanoma was pT1aN3, pTisNx, pTxNxM1b, and pT3bN0. Patients with melanoma were treated with penile sparing surgery; two are alive without disease, one is alive with disease, and one patient with metastasis at presentation died of disease at 16.3 months. The patients with sarcoma and deep-seated or node-positive disease died of disease at a mean of 49.7 months. Two patients with EPD were treated with wide local excision of the lesions and were both pT1Nx. The remaining patient had sebaceous carcinoma treated with excisional biopsy and was free of disease at 32.0 months. CONCLUSIONS: Non-SCC of the penis is primarily treated surgically, with the goal of complete excision at the time of treatment. The utilization of lymphadenectomy is less clear in these malignancies, but aggressive approaches should be considered in appropriate patients. Tumor stage and nodal status are important in determining patient outcomes.

Secondary pelvic congestion syndrome: description and radiographic diagnosis.

INTRODUCTION: Pelvic congestion syndrome (PCS) is a complex condition of the pelvic venous system leading to nonspecific pelvic pain that was initially described in females alone. The underlying abnormalities, though diverse, all result in increased pressure in the left gonadal vein which is transmitted retrograde into the pelvic venous system. Our primary aim was to describe our findings of secondary PCS as a distinct entity from primary PCS in that it has an identifiable vascular etiology and is gender nonspecific. We also aimed to assess the adequacy of late-arterial phase CT urography (CTU) as the initial imaging modality in diagnosing and evaluating secondary PCS. MATERIALS AND METHODS: We retrospectively reviewed 59 patients with PCS, 36 males and 23 females ages 24 to 63, from 2000-2011. To maximize opacification, CTU images were taken in the late-arterial phase with a 35-50 second delay after contrast administration. RESULTS: Review of our cases revealed multiple etiologies for PCS, including: Nutcracker syndrome (19 cases), cirrhosis (17), retroaortic left renal vein (11), tumor thrombosis of the IVC (5), portal vein thrombosis (4), renal cell carcinoma with left renal vein thrombosis (2), and left kidney AVF (1). The most common symptom was unexplained chronic pelvic pain. The patients in our series had clearly identifiable vascular flow abnormalities leading to the development of PCS, and were therefore diagnosed as having secondary PCS. All cases were easily identified utilizing CTU to visualize and measure dilation of the left gonadal vein and pelvic varices. This modality also proved valuable in the identification and management of the various underlying causes of secondary PCS. CONCLUSION: Secondary PCS is distinct from primary PCS in that it arises from clearly identifiable vascular flow abnormalities and occurs in both males and females. The diverse set of underlying etiologies, as well as the resulting congested varices, can be reliably and adequately visualized using CTU as the initial imaging modality.

Contemporary management of penile cancer: greater than 15 year MSKCC experience.

INTRODUCTION: Penile cancer is a rare malignancy, and few guidelines are available to define treatment paradigms. For greater understanding of the natural history of surgically treated penile cancer, we analyzed the experience at our institution. MATERIALS AND METHODS: Using an institutional database, we identified 127 patients treated for squamous cell carcinoma of the penis from 1995-2011. Cancer-specific survival (CSS) was calculated using the Kaplan-Meier method. Survival data were compared using the log-rank test. The difference in risk of cancer-specific death by lymph node status and histological grade was determined by univariate Cox regression analysis. RESULTS: Five year CSS for pTis, pT1, pT2, and pT3/4 was 100%, 84% (95% CI 58%-95%), 54% (95% CI 33%-71%), and 54% (95% CI 25%-76%), respectively (p ≤ .005). Three year CSS for patients with N0, N+, and Nx disease was 90% (95% CI 47%-99%), 65% (95% CI 47%-79%), and 86% (95% CI 73%-93%), respectively (p = .03). The receipt of neoadjuvant chemotherapy did not change per 5 year period over the 16 years of our study. Median follow up was 2.8 years. CONCLUSIONS: Penile cancer patients with advanced disease had poor survival. Tumor stage and nodal status were significant predictors of CSS. Penis-sparing approaches may be considered for most patients; however, pathological stage and grade dictate the management and ultimate outcome. Further studies are necessary to clarify the benefits of chemotherapy in this disease.
