ABSTRACT

OBJECTIVE: To solicit information/suggestions from prostate cancer survivors to improve survivorship experiences specific to work/workability. DESIGN: The study employed a qualitative/phenomenological approach. Black/African-American and white prostate cancer survivors who: (1) had prostatectomy or radiation therapy 6-36 months prior, (2) were working for pay within 30 days before having treatment, and (3) expected to be working for pay 6 months later (n = 45) were eligible for this study. Survivors were engaged in 60-to-90-minute structured interviews. Content analysis was used to ascertain prominent themes. RESULTS: Participants had the following recommendations for survivors: ask about research on treatment options and side effects; speak with other survivors about cancer diagnosis; and inform family/friends and employers about needed accommodations. Considerations for family/friends emphasized the significance of instrumental (e.g. help finding information) and emotional support (e.g. encouragement). Employer/co-worker considerations most often related to work-related accommodations/support and avoiding stigmatization of the survivor. Considerations for healthcare providers commonly included the provision of unbiased, plain-language communication about treatment options and side effects. No major differences existed by race. CONCLUSIONS: Needs of employed PrCA survivors, regardless of their race or treatment type, are commonly related to their desire for informational, instrumental, and/or emotional support from family/friends, employers/co-workers, and healthcare providers. The requested supports are most often related to the side effects of prostate cancer treatment.

ABSTRACT

INTRODUCTION: Prostate cancer screening has routinely identified men with very low- or low-risk disease, per the National Comprehensive Cancer Network guidelines. Current literature has demonstrated that the most appropriate management strategy for these patients is active surveillance (AS). The mainstay of AS includes periodic biopsies and biannual prostate-specific antigen tests. However, multiparametric magnetic resonance imaging (mpMRI) is uniquely posed to improve patient surveillance. This study aimed to evaluate the utility of an annual mpMRI in patients on AS, focusing on radiologic upgrading and Prostate Imaging-Reporting and Data System (PI-RADS) trends as indicators of clinically significant disease. METHODS: This prospective, single intuition, study enrolled 208 patients on AS who had at least two biopsies and 1 mpMRI with a median follow-up of 5.03 years. The main outcome variable was time to Gleason grade (GG) reclassification. RESULTS: After delineating patients on their initial PI-RADS score, men with score 3 and 5 lesions at first MRI had comparable GG reclassification-free survival to their counterparts. Conversely, men with initial PI-RADS 4 lesions showed a lower 5-year GG reclassification-free survival compared to those with PI-RADS score 1-2. The cohort was then subset to 70 patients who obtained ≥2 mpMRIs on protocol. Men experiencing uptrending mpMRI scores had an increased risk of GG reclassification, with a 35.4% difference in 5 year GG reclassification-free survival probability on the Kaplan-Meier curve analysis. CONCLUSION: In conclusion, this study demonstrates that for men on AS with stable recapitulated disease, an annual MRI may replace repeat biopsies after confirmatory sampling has been obtained. On the other hand, men who initiate AS with PI-RADS 4 and/or who display uptrending mpMRI scores require periodic biopsies along with repeat imaging. This study highlights the utility of integrating an annual MRI into AS protocols, thus promising a more effective approach to management.

ABSTRACT

INTRODUCTION: This study aimed to evaluate if race impacted outcomes or risk of disease progression in men on active surveillance (AS) for prostate cancer. We present the results from our majority African-American cohort of men in an equal access setting over a 5-year follow-up period. PATIENTS AND METHODS: All patients who elected AS for prostate cancer at the Southeast Louisiana Veterans Health Care System are entered into a prospectively managed observational database. Patients were divided into groups based on self-reported race. Grade group progression was defined as pathologic upgrading above International Society of Urological Pathology Grade Group 1 disease on subsequent biopsies following diagnostic biopsy. All tests were 2 sided using a significance of .05. RESULTS: A total of 228 men met inclusion criteria in the study, including 154 non-Hispanic African American and 74 non-Hispanic Caucasian American men, with a median follow-up of 5 years from the initiation of AS. Race was not predictive of Gleason grade progression, AS discontinuation, or biochemical recurrence on Cox multivariate analysis (HR = 1.01, 0.94, 0.85, P = .96, .79, .81, respectively). On Kaplan-Meier analysis at 5 years, African-American progression-free, AS discontinuation free, and overall survival probability was comparable to their Caucasian American counterparts (P > .05 for all). CONCLUSIONS: Active surveillance is a safe treatment option for low and very low risk prostate cancer, regardless of race. African-American and Caucasian-American men did not have any significant difference in Gleason grade group progression in our cohort with 5-year follow-up.

ABSTRACT

Prostate cancer is the most common malignancy in American men following skin cancer, with approximately one in eight men being diagnosed during their lifetime. Over the past several decades, the treatment of prostate cancer has evolved rapidly, so too has screening. Since the mid-2010s, magnetic resonance imaging (MRI)-guided biopsies or 'targeted biopsies' has been a rapidly growing topic of clinical research within the field of urologic oncology. The aim of this publication is to provide a review of biparametric MRI (bpMRI) utilization for the diagnosis of prostate cancer and a comparison to multiparametric MRI (mpMRI). Through single-centered studies and meta-analysis across all identified pertinent published literature, bpMRI is an effective tool for the screening and diagnosis of prostate cancer. When compared with the diagnostic accuracy of mpMRI, bpMRI identifies prostate cancer at comparable rates. In addition, when omitting dynamic contrast-enhanced (DCE) protocol to the MRI, patients incur reduced costs and shorter imaging time while providers can offer more tests to their patient population.

ABSTRACT

OBJECTIVE: To evaluate the risk upgrading of active surveillance (AS), we reviewed the outcomes of African American men (AA) after electing AS. AS is the standard of care for men with low-grade prostate cancer (PCa). AA are known to have more advanced PCa features and are more likely to die from PCa, thus subsequent disease progression for AA on AS is unclear. METHODS: A prospectively maintained AS database from the Southeast Louisiana Veterans Administration Medical Center, New Orleans, Lousiana was queried. We identified men with low- and very low-risk PCa (Gleason 3 + 3, PSA <10, ≤CT2a) who had undergone at least 2 prostate biopsies, including initial diagnostic and subsequent confirmatory prostate biopsies. Descriptive and comparative statistical analysis was performed using R version 3.5.1. RESULTS: From a total of 274 men on AS (70% AA), 158 men met inclusion criteria (104 AA [66%]). All patients underwent at least 2 biopsies, and 29% underwent 3 or more biopsies. The median follow-up was 2.7 years. At 3 years on AS protocol, 57% AA and 61% Caucasians demonstrated no evidence of upgrading or treatment. No significant difference was observed between upgrading or progression to treatment when comparing racial groups. Seven (4%) patients in this cohort died from non PCa-specific causes, but no patients demonstrated metastasis or death from PCa over the course of study. CONCLUSION: AA men with low-risk PCa can be safely followed with the same AS protocol as non-AA men. Further analysis with longer follow up is ongoing.

ABSTRACT

INTRODUCTION: Neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte ratios (PLR) are useful clinical biomarkers for prognosis in several malignancies. Their predictive value has been less clearly demonstrated with prostate cancer (PCa), particularly, their utility within active surveillance (AS) protocols. We aim to evaluate NLR and PLR in AS patients. METHODS: We identified 98 patients who met inclusion criteria in our cohort of 274 men diagnosed with PCa on AS. Patients were then categorized into high and low NLR and PLR groups. RESULTS: The 2.5 and 5-year Gleason upgrading free probability for our high NLR cohort was 73.9%(CI 56.3% to 97.0%) and 46.2%(CI 22.4% to 95.1%) compared to 76.3%(CI 65.7% to 88.7%) and 61.7%(CI 47.7% to 80.0%) in the low NLR cohort(p = .73). The 2.5 and 5-year Gleason upgrading free probability for our High PLR cohort was 73.5%(CI 57.3% to 94.2%) and 60.1(CI 41.4% to 87.4%) compared to 76.8%(CI 65.8% to 89.65) and 58.1%(CI 42.2% to 80.1%) in our low PLR group(p = .41). A multivariant analysis demonstrated these groups were not significant predictors of upgrading or treatment. CONCLUSION: Despite their usefulness in many types of malignancy, NLR and PLR were not predictors of upgrading or treatment in men on AS for localized PCa in our cohort.

ABSTRACT

Development of ureteroanastamotic strictures (UAS) after urinary diversion is not uncommon, but is challenging to treat. Poor outcomes are likely with endoscopic and radiologic management, and definitive surgical treatment can cause significant morbidity. The comparative advantages of an operative approach have not yet been fully described in the literature. We retrospectively reviewed the prospectively maintained Tulane University Department of Urology quality assurance database of 12 patients who underwent operative UAS repair between 2012 and 2018. Data were reviewed for operative approach, demographics, baseline disease characteristics, operative variables, and perioperative and pathological outcomes. Of the 12 patients analyzed, 5 underwent open repair (OR) (2 bilateral, 2 right, 1 left) and 7 underwent robotic repair (RR) (3 right, 4 left). One robotic case required conversion to open due to significant intestinal and peri-ureteral adhesions. The median ages were 59 years in OR and 60 years in RR. Two patients in each group had failed previous endoscopic repair. Median time from cystectomy to treatment of enteroanastamotic stricture was 13 months for OR and 10 months for RR (p = 0.25). Median estimated blood loss was 80 mL in both OR and RR (p = 1.0), median operative time was 260 min in OR and 255 min in RR (p = 0.13), and median hospital stay was 8 and 4 days, respectively (p = 0.06). There were two intra-operative and one post-operative complication in the OR group, one of whom required further surgical intervention, and no complications in the robotic cohort. A minimally invasive, robotic approach offers a non-inferior alternative to OR with similar outcomes for appropriately selected patients with UAS. High success rates combined with minimal morbidity may provide definitive therapy at an earlier stage of the stricture state.

ABSTRACT

INTRODUCTION: The objective of this study was to characterize the demographic, prognostic, and treatment factors for patients with primary adenocarcinoma of the bladder by analyzing the impact of histologic subtype in a large sample size and interpreting newly released Surveillance, Epidemiology, and End Results (SEER) chemotherapy data. MATERIALS AND METHODS: The SEER 18 Registry was utilized to identify cases of primary adenocarcinoma diagnosed from 1973 to 2015. Demographic data, tumor and disease characteristics, treatment information, and survival outcome data were collected. Overall survival and disease-specific survival were determined using Kaplan-Meier curve analysis. Univariate and multivariate Cox regression analysis were then completed using SAS JMP. RESULTS: A total of 2305 cases of primary adenocarcinoma of the bladder were identified. Overall survival at 2-, 5- and 10-year intervals was 54.8%, 36.1%, and 25.4%, respectively. Disease-specific survival at 2-, 5- and 10-year intervals was 62.0%, 47.1%, and 40.1%, respectively. Patients were treated with surgery (86.4%), chemotherapy (21.9%), and radiation (15.0%) (P < .0001). Multivariate Cox regression analysis showed independent prognostic value for gender, stage, grade, primary tumor location, and histologic subtype. The urachus/dome location conferred survival advantage over non-urachal locations on univariable and multivariable Cox regression analysis. The papillary adenocarcinoma subtype conferred the best survival outcome, whereas signet cell carcinoma (hazard ratio, 2.069; P < .0001) and unclassified adenocarcinoma (not otherwise specified) (hazard ratio, 1.524; P < .0001) conferred the worst prognoses. CONCLUSION: This study utilized a population-based analysis to showcase the utility of various prognostic features in primary bladder adenocarcinoma cases. In characterizing treatments, we find the prevailing treatment remains surgical intervention, whereas a sizable minority receives chemotherapy and/or radiation, often in combination with surgery.

ABSTRACT

We present a urologic case report associated with retinoblastoma (RB1) mutation. A 65-year-old man, who has a history of bilateral retinoblastoma treated with primary radiation therapy at approximately 1 year of age. He presented with a 3-month history of gross hematuria and, on initial workup, was found to have synchronous renal and urothelial malignancies. The patient underwent complete transurethral resection of high grade Ta urothelial cancer and robotic-assisted partial nephrectomy for a pT3a leiomyosarcoma. He remains responsive to Bacillus Calmette-Guerin, and shows no recurrence of his renal malignancy. Through targeted sequencing, Rb mutations can predispose patients to several urologic malignancies.

ABSTRACT

The use of light as a means of therapy for bladder cancer has a long history but has been hampered by a lack of tumor specificity and therefore, damage to the normal bladder mucosa. Here, we describe a targeted form of phototherapy called photoimmunotherapy (PIT), which targets EGFR-expressing bladder cancer. Anti-EGFR antibody panitumumab was labeled with the photoabsorber (PA), IRDye 700Dx (IR700), to create a panitumumab-IR700 antibody-PA conjugate that is activated by near-infrared radiation (NIR). Bladder cancer tissue microarray (TMA) and bladder cancer cell lines were analyzed for expression of EGFR. Mechanism of PIT-induced cell death was studied using proliferation assays, transmission electron microscopy (TEM), and production of reactive oxygen species. Finally, the in vivo effect was studied in xenografts. EGFR staining of TMAs showed that while most bladder cancers have expression of EGFR to a varying degree, squamous cell carcinomas (SCC) have the highest expression of EGFR. Panitumumab-IR700 activated by NIR light rapidly killed UMUC-5 cells, a bladder SCC line. Panitumumab alone, panitumumab-IR700 without NIR, or NIR alone had no effect on cells. TEM demonstrated that cell death is due to necrosis. Singlet oxygen species contributed toward cell death. NIR-PIT with panitumumab-IR700 reduced growth compared with only panitumumab-IR700-treated UMUC-5 xenograft tumors. PIT is a new targeted treatment for bladder cancer. Panitumumab-IR700-induced PIT selectively kills EGFR-expressing bladder cancer cells in vitro and in vivo and therefore warrants further therapeutic studies in orthotopic xenografts of bladder cancer and ultimately in patients.

ABSTRACT

Heat shock protein 90 (HSP90) inhibition is an attractive strategy for cancer treatment. Several HSP90 inhibitors have shown promising effects in clinical oncology trials. However, little is known about HSP90 inhibition-mediated bladder cancer therapy. Here, we report a quantitative proteomic study that evaluates alterations in protein expression and histone post-translational modifications (PTMs) in bladder carcinoma in response to HSP90 inhibition. We show that 5 HSP90 inhibitors (AUY922, ganetespib, SNX2112, AT13387, and CUDC305) potently inhibited the proliferation of bladder cancer 5637 cells in a dose- and time-dependent manner. Our proteomic study quantified 518 twofold up-regulated and 811 twofold down-regulated proteins common to both AUY922 and ganetespib treatment. Bioinformatic analyses revealed that those differentially expressed proteins were involved in multiple cellular processes and enzyme-regulated signaling pathways, including chromatin modifications and cell death-associated pathways. Furthermore, quantitative proteome studies identified 14 types of PTMs with 93 marks on the core histones, including 34 novel histone marks of butyrylation, citrullination, 2-hydroxyisobutyrylation, methylation, O-GlcNAcylation, propionylation, and succinylation in AUY922- and ganetespib-treated 5637 cells. Together, this study outlines the association between proteomic changes and histone PTMs in response to HSP90 inhibitor treatment in bladder carcinoma cells, and thus intensifies the understanding of HSP90 inhibition-mediated bladder cancer therapeutics.

ABSTRACT

PURPOSE: To investigate the association of sarcopenia (muscle mass wasting) with complications and survival in patients undergoing radical nephrectomy for advanced kidney cancer. PATIENTS AND METHODS: We identified 137 patients with stage III and IV kidney cancer who underwent radical nephrectomy between 2008 and 2012. Preoperative cross-sectional imaging was used to measure total psoas area (TPA) at the level of L3 and controlled for height (m(2)). Sarcopenia was identified as TPA in the lowest gender-specific quartile. Patient characteristics and postoperative complications were compared between sarcopenic and nonsarcopenic patients. Kaplan-Meier survival curve estimates were generated for overall and gender-specific survival. RESULTS: Preoperative cross-sectional imaging was available for 128 patients (93%, 85 men and 43 women). Mean TPA for men was 5.49 cm(2)/m(2) versus 4.27 cm(2)/m(2) for women (P < 0.05). Sarcopenia was associated with risk of Clavien grade III or higher complication (P = 0.03) and node-positive disease (P = 0.01). Median follow-up was 48.3 months. Kaplan-Meier estimates of overall and gender-specific survival were similar between sarcopenic and nonsarcopenic patients. CONCLUSION: Sarcopenia appears to be associated with risk of major complication after radical nephrectomy for advanced kidney cancer. It was not related to overall survival, however. This preoperative imaging tool may be helpful in preoperative counseling and preparation.

ABSTRACT

BACKGROUND: Vulvovaginitis has a known association with urinary tract infections (UTIs) in girls. We hypothesize that vulvovaginitis is a major contributor to UTIs in prepubertal girls by increasing periurethral colonization with uropathogens. METHODS: Periurethral swabs and urine specimens were obtained from a total of 101 girls (58 with vulvovaginitis and 43 without vulvovaginitis). Specimens were cultured for bacterial growth. The dominant organism in the periurethral swabs and urine cultures was recorded and antibiotic sensitivity profiles were compared. RESULTS: Periurethral swabs from children with vulvovaginitis were associated with a statistically significant increase in uropathogenic bacteria (79% Enterococcus species or Escherichia coli) as the dominant culture compared with swabs from girls without vaginitis (18%) (p < 0.05). In children with vulvovaginitis, 52% of the urine cultures were positive for UTIs, and the dominant organism in the urine cultures matched the species and antibiotic sensitivity profile of the corresponding periurethral swab. Only 11% of the urine cultures from girls without vulvovaginitis were positive for UTIs. CONCLUSIONS: Vulvovaginitis may cause UTIs by altering the perineal biome such that there is increased colonization of uropathogens.

ABSTRACT

OBJECTIVE: To determine whether age of toilet training is associated with dysfunctional voiding in children. MATERIALS AND METHODS: We compared patients referred to the urologic clinics for voiding dysfunction with age-matched controls without urinary complaints. Characteristics including age and reason for toilet training, method of training, and encopresis or constipation were compared between both groups. RESULTS: Initiation of toilet training prior to 24 months and later than 36 months of age were associated with dysfunctional voiding. However, dysfunctional voiding due to late toilet training was also associated with constipation. CONCLUSION: Dysfunctional voiding may be due to delayed emptying of the bowel and bladder by children. The symptoms of dysfunctional voiding are more common when toilet training early, as immature children may be less likely to empty in a timely manner, or when training late due to (or in association with) constipation.

ABSTRACT

The technique of robotic partial nephrectomy continues to evolve, but the goals remain the same. Achievement of pentafecta outcomes is difficult to obtain; however, surgeons should continue to strive for this standard of excellence. The future continues to be bright for patients and surgeons alike in continuing to perform robot-assisted partial nephrectomy.

ABSTRACT

OBJECTIVE: To evaluate if statin medications (3-hydroxyl-3-methylglutaryl coenzyme A [HMG-CoA] reductase inhibitors) improve either oncologic or renal functional outcomes for patients undergoing robot-assisted partial nephrectomy (RPN). PATIENTS AND METHODS: Patients undergoing RPN between March 2008 and October 2013 were evaluated from a prospectively maintained database for statin usage. The rate of perioperative acute kidney injury (AKI), as defined according to the RIFLE criteria, and the progression of chronic kidney disease (CKD) were compared between users and nonusers. Oncologic outcomes and rate of progression were compared between users and nonusers. RESULTS: One hundred four (31%) of 339 patients were on statin therapy preoperatively and continued this medication peri- and postoperatively. Statin patients were older and had higher rates of comorbidities, including coronary artery disease, diabetes, and hypertension (p<0.0001 for all).The rate of AKI in the statin (16%) and nonstatin patients (14%) (p=0.60) and CKD progression based on Kaplan-Meier estimates (p=0.57) were similar between both the groups. Subgroup analysis of the 271 (80%) patients with hilar clamping also had similar rates of AKI, in statin users 10% vs 12% in nonusers (p=0.50). Multivariate analysis of factors affecting CKD progression confirmed these findings. Oncologic progression was not affected by statin therapy (p=0.90). CONCLUSION: Statin medications do not appear to influence perioperative renal function following RPN, in either clamped or unclamped procedures. Continuation of these medications may be continued perioperatively, but any effect on renal functional or oncologic outcomes was not elucidated in this study.

ABSTRACT

OBJECTIVE: To compare perioperative morbidity and oncological outcomes of robot-assisted laparoscopic radical cystectomy (RARC) to open RC (ORC) at a single institution. PATIENTS AND METHODS: A retrospective analysis was performed on a consecutive series of patients undergoing RC (100 RARC and 100 ORC) at Wake Forest University with curative intent from 2006 until 2010. Complication data using the Clavien system were collected for 90 days postoperatively. Complications and other perioperative outcomes were compared between patient groups. RESULTS: Patients in both groups had comparable preoperative characteristics. The overall and major complication (Clavien ≥ 3) rates were lower for RARC patients at 35 vs 57% (P = 0.001) and 10 vs 22% (P = 0.019), respectively. There were no significant differences between groups for pathological outcomes, including stage, number of nodes harvested or positive margin rates. CONCLUSION: Our data suggest that patients undergoing RARC have perioperative oncological outcomes comparable with ORC, with fewer overall or major complications. Definitive claims about comparative outcomes with RARC require results from larger, randomised controlled trials.

ABSTRACT

OBJECTIVE: To evaluate the impact of increased experience in robot-assisted partial nephrectomy (RAPN) on perioperative and oncological outcomes To detail the complications encountered in establishing a RAPN programme at a tertiary referral centre and the factors associated with these complications. PATIENTS AND METHODS: The initial consecutive 233 patients undergoing RAPN between March 2008 and May 2012 at our institution were identified. Patients were divided into quartiles to evaluate outcomes, and uni- and multivariate predictors of complications were calculated. RESULTS: In progressive quartiles, patients tended to have more complex renal tumours as evaluated by R.E.N.A.L. nephrometry (P < 0.01) or preoperative aspects and dimensions used for an anatomical classification (PADUA) scores (P = 0.003), and percentage endophytic (P = 0.01). Developing technique increased the patients undergoing unclamped PN (P < 0.01). The mean time in the operating room (from skin incision to closure) decreased significantly from 225 to 183 min (P < 0.01) and warm ischaemia time decreased from 28 to 15 min, when clamping (P < 0.01). Clavien graded complication rate (P = 0.26) and positive margin rate (P = 0.32) was unchanged by quartile. CONCLUSION: We show that increasing experience allows more complex tumours to be removed with similar outcomes in patients undergoing RAPN. The complication rates and perioperative outcomes were similar in four successive quartiles of an initial experience of RAPN.

ABSTRACT

PURPOSE: To evaluate if hematologic parameters and inflammatory markers could predict extravesical tumor and overall survival after radical cystectomy for patients with recurrent high grade T1 or muscle-invasive bladder cancer. PATIENTS AND METHODS: A total of 68 consecutive cases of radical cystectomy performed with curative intent at our institution between April 2005 and October 2011 with preoperative hematologic parameters are included in this analysis. We evaluated preoperative characteristics with univariable and multivariate Cox proportional hazard ratios to assist in risk stratification for overall survival. Relative risk (RR) ratios and 95% confidence intervals (CI) were created. We also identified factors associated with extravesical tumor extension with logistic regression analysis. RESULTS: Median overall survival in the total cohort was 25 months (95% CI 13-61). In multivariate analysis, neutrophil/lymphocyte ratio <2.5 (RR 2.49; 95% CI 1.14-6.09), hypoalbuminemia (RR 4.96; 95% CI 2.18-11.67), pT3/4 (RR 7.97, 95% CI 3.16-24.83), and lymph node positive disease (RR 2.62, 95% CI 1.26-5.46) predicted overall survival. These were statistically significant for cancer-specific survival as well. Both elevated neutrophil/lymphocyte ratio (RR 3.18, 95% CI 1.09-9.79) and hypoalbuminemia (RR 3.72, 95% CI 1.12-15.00) were associated with risk for extravesical disease. CONCLUSIONS: Serum neutrophil/lymphocyte ratio and hypoalbuminemia predict overall and cancer-specific survival in patients undergoing radical cystectomy for muscle-invasive bladder cancer. These parameters also predict risk for extravesical disease. These could be combined with other established preoperative parameters to improve risk stratification and preoperative counseling.

ABSTRACT

INTRODUCTION: Indocyanine green (ICG) is emerging as a potential adjunct to robot-assisted partial nephrectomy by its ability to aid in the real-time identification of renal vasculature, renal masses, and the renal mass-parenchymal margin. The fluorescence patterns of renal masses have not been adequately described according to histology, and it remains unknown if fluorescence pattern can reliably predict histology or malignancy. We therefore describe the ICG fluorescence pattern of our first 100 robot-assisted partial nephrectomies (RAPN) and correlate with histology. MATERIALS AND METHODS: We reviewed our prospective RAPN database and categorized fluorescence pattern as isofluorescent (same as surrounding parenchyma), hypofluorescent (less than surrounding parenchyma, but with uptake), or afluorescent (no visible uptake of dye). Descriptive statistics were applied. RESULTS: All 14 cystic lesions were afluorescent and comprised 9 malignant and 5 benign masses. Eighty-six lesions were solid, of which 3 were isofluorescent including two clear-cell and one translocation tumor. The remaining 83 solid lesions were hypofluorescent and included 65 malignant and 18 benign lesions. Clear-cell was the most common histology of which 96% were hypofluorescent and 4% isofluorescent. In determining malignant vs benign lesions, hypofluorescence had a positive predictive value of 87%, negative predictive value of 52%, sensitivity of 84%, and specificity of 57%. CONCLUSIONS: A three-grade classification of renal mass ICG fluorescence pattern is correlated with some histologic findings but unable to reliably predict malignant vs benign lesions.
