RESUMEN
BACKGROUND: Elicitation of patients' preferences is an integral part of shared decision-making, the recommended approach for prostate cancer decision-making. Existing decision aids for this population often do not specifically focus on patients' preferences. Healium is a brief interactive web-based decision aid that aims to elicit patients' treatment preferences and is designed for a low health literate population. OBJECTIVE: This study used a randomized controlled trial to evaluate whether Healium, designed to target preference elicitation, is as efficacious as Healing Choices, a comprehensive education and decision tool, in improving outcomes for decision-making and emotional quality of life. METHODS: Patients diagnosed with localized prostate cancer who had not yet made a treatment decision were randomly assigned to the brief Healium intervention or Healing Choices, a decision aid previously developed by our group that serves as a virtual information center on prostate cancer diagnosis and treatment. Assessments were completed at baseline, 6 weeks, and 3 months post baseline, and included decisional outcomes (decisional conflict, satisfaction with decision, and preparation for decision-making), and emotional quality of life (anxiety/tension and depression), along with demographics, comorbidities, and health literacy. RESULTS: A total of 327 individuals consented to participate in the study (171 were randomized to the Healium intervention arm and 156 were randomized to Healing Choices). The majority of the sample was non-Hispanic (272/282, 96%), White (239/314, 76%), married (251/320, 78.4%), and was on average 62.4 (SD 6.9) years old. Within both arms, there was a significant decrease in decisional conflict from baseline to 6 weeks postbaseline (Healium, P≤.001; Healing Choices, P≤.001), and a significant increase in satisfaction with one's decision from 6 weeks to 3 months (Healium, P=.04; Healing Choices, P=.01). Within both arms, anxiety/tension (Healium, P=.23; Healing Choices, P=.27) and depression (Healium, P=.001; Healing Choices, P≤.001) decreased from baseline to 6 weeks, but only in the case of depression was the decrease statistically significant. CONCLUSIONS: Healium, our brief decision aid focusing on treatment preference elicitation, is as successful in reducing decisional conflict as our previously tested comprehensive decision aid, Healing Choices, and has the added benefit of brevity, making it the ideal tool for integration into the physician consultation and electronic medical record.

OBJECTIVES: Prostate cancer (PCa) survivors report poor physical functioning alongside negative psychological outcomes as they cope with treatment side effects and practical concerns after treatment completion. This study evaluated PROGRESS, a web-based intervention designed to improve adaptive coping among PCa survivors. METHODS: Localized PCa patients (N = 431) within one year of treatment completion were randomized to receive educational booklets or PROGRESS + educational booklets. Surveys completed at baseline, 1-, 3-, and 6-months assessed patient characteristics; functional quality of life and coping (primary outcomes); and psychosocial outcomes (e.g., self-efficacy, marital communication; secondary outcomes). Intent-to-treat and as-treated analyses were completed to assess change in outcomes from baseline to 6 months using linear mixed effects regression models. RESULTS: In the intent-to-treat analyses, participants randomized to the intervention group had improved diversion coping (i.e., healthy redirection of worrying thoughts about their cancer), but more difficulties in marital communication (ps < 0.05). However, PROGRESS usage was low among those randomized to the intervention group (38.7%). The as-treated analyses found PROGRESS users reported fewer practical concerns but had worse positive coping compared to PROGRESS non-users (ps < 0.05). CONCLUSIONS: The findings suggest PROGRESS may improve certain aspects of adaptive coping among PCa survivors that use the website, but does not adequately address the remaining coping and psychosocial domains. Additional research is needed to better understand the gaps in intervention delivery contributing to low engagement and poor improvement across all domains of functional quality of life and adaptive coping.

BACKGROUND, CONTEXT AND PURPOSE: In spite of the mixed evidence for their impact, survivorship Care Plans (SCPs) are recommended to enhance quality of care for cancer survivors. Data on the feasibility of SCPs in bladder cancer (BC) is sparse. Using a mixed-methods approach, this study describes the iterative development, acceptability and feasibility of BC specific SCP (BC-SCP) in clinical settings. METHODS: In Phase I, we developed the BC-SCP. In Phase II, we conducted four focus groups with 19 patients and 15 providers to examine its acceptability and usability challenges. Data analyses using the Atlas.ti program, informed refinement of the BC-SCP. In Phase III, we conducted feasibility testing of the refined BC-SCP with 18 providers from 12 health-centers. An encounter survey was completed after each assessment to examine the feasibility of the BC-SCP. Chi-square and Fisher Exact tests were used for comparative analyses. RESULTS: During phase I, we observed high patient and provider acceptability of the BC-SCP and substantial engagement in improving its content, design, and structure. In Phase II, providers completed 59 BC-SCPs. Mean time for BC-SCP completion was 12.3 min. Providers reported that BC-SCP content was clear, did not hamper clinic flow and was readily completed with easy-to-access information. Comparative analyses to examine differences in SCP completion time by patient clinico-demographic characteristics and provider type revealed no significant differences. CONCLUSIONS: Our BC-SCP has clinical relevance, and can be used in an active practice setting. However, considerable progress will be necessary to achieve implementation of and sharing the BC-SCP with patients and care providers, particularly within the electronic medical record. In summary, BC-SCPs are essential to improve the follow up care of BC survivors. Clinical resources are required to ensure appropriate implementation of BC-SCPs.

PURPOSE: Prostate cancer patients who have undergone androgen deprivation therapy (ADT) may experience cognitive impairment, yet there is an unmet need for nonpharmacological interventions to address cognitive impairment in this population. This study examines the feasibility, acceptability, and preliminary efficacy of a home-based computerized cognitive training (CCT) program to treat cancer-related cognitive impairment. METHODS: Sixty men who had received ≥ 3 months of ADT were screened for at least mild cognitive or neurobehavioral impairment and randomized to 8 weeks of CCT or usual care. Follow-up assessments occurred immediately post-intervention or equivalent (T2) and 8 weeks later (T3). The acceptability of CCT was also assessed. RESULTS: Feasibility:A priori feasibility thresholds were partially met (i.e., randomization rate > 50%, retention rate > 70% excluding CCT drop-outs, but < 70% for intent-to-treat). Acceptability: Participants were mostly satisfied with CCT and found it somewhat enjoyable, though barriers to uptake existed. Preliminary efficacy: Linear mixed models indicated significant time by group effects favorable to CCT in reaction time (p = .01), but unfavorable to CCT in verbal and visual memory (ps < .05). Memory was temporarily suppressed in the CCT group at T2, but normalized by T3. There was no effect of CCT on self-reported cognitive functioning, neurobehavioral functioning, nor quality of life. CONCLUSIONS: This study provides tentative support for the feasibility and acceptability of CCT to treat mild cognitive impairment in ADT patients. CCT had a beneficial effect on reaction time, but temporarily suppressed memory. CCT's benefits may be limited to a narrow area of functioning. Larger-scale studies are needed.

PURPOSE: We studied recurrence-free survival after partial vs radical nephrectomy for clinical stage T1 renal cell carcinoma in all patients and in those up staged to pathological stage T3a. MATERIALS AND METHODS: We retrospectively reviewed the records of 1,250 patients who underwent partial or radical nephrectomy for clinically localized T1 renal cell carcinoma between 2006 and 2014. Recurrence-free survival was estimated using the Kaplan-Meier method and evaluated as a function of nephrectomy type with the log rank test and Cox models, adjusting for clinical, radiological and pathological characteristics. RESULTS: A total of 86 recurrences (7%) were observed during a median followup of 37 months. No difference in recurrence-free survival between partial and radical nephrectomy was found among all clinical stage T1 renal cell carcinomas. T3a up staging was noted in 140 patients (11%) and recurrent disease was observed in 44 (31.4%) during a median followup of 38 months. Among up staged T3a cases partial nephrectomy was associated with shorter recurrence-free survival compared to radical nephrectomy on univariable analysis (recurrence HR 2.04, 95% CI 1.12-3.68, p = 0.019) and multivariable analysis (recurrence HR 5.39, 95% CI 1.94-14.9, p = 0.001). CONCLUSIONS: In a subgroup of patients clinically staged T1 renal cell carcinoma will be pathologically up staged to T3a. Among these patients those who undergo partial nephrectomy appear to have inferior recurrence-free survival relative to those who undergo radical nephrectomy.

PURPOSE: Although improvements in perioperative care have decreased surgical morbidity after radical cystectomy for muscle invasive bladder cancer, treatment side effects still have a negative impact on patient quality of life. We examined unmet patient needs along the illness trajectory. MATERIALS AND METHODS: A total of 30 patients (26.7% women) treated with cystectomy and urinary diversion for muscle invasive bladder cancer participated in the study. Patients were recruited from the Department of Urology at Mount Sinai and through advertisements on the Bladder Cancer Advocacy Network (BCAN) website between December 2011 and September 2012. Data were collected at individual interviews, which were audiotaped and transcribed. Transcribed data were quantitatively analyzed to explore key unmet needs. RESULTS: At diagnosis unmet informational needs were predominant, consisting of insufficient discussion of certain topics, including urinary diversion options and their side effects, self-care, the recovery process and medical insurance. Unmet psychological needs related to depression, and worries about changes in body image and sexual function were reported. Postoperative unmet needs revolved around medical needs (eg pain and bowel dysfunction) and instrumental needs (eg need of support for stomal appliances, catheters and incontinence). During survivorship (ie 6 to 72 months postoperatively) unmet needs centered around psychological support (ie depression, poor body image and sexual dysfunction) and instrumental support (eg difficulty adjusting to changes in daily living). CONCLUSIONS: Meeting patient needs is imperative to ensure adequate patient involvement in health care and enhance postoperative quality of life. An effective support provision plan should follow changes in patient needs.

BACKGROUND: Cytoreductive surgery (CRS) with heated intraperitoneal chemotherapy (HIPEC) has gained acceptance in the treatment of peritoneal carcinomatosis with reported morbidity and mortality rates of 27-56 and 0-11 %, respectively. The safety and oncologic outcome of genitourinary repair at the time of CRS and HIPEC remains unclear. METHODS: We identified 170 patients who underwent CRS-HIPEC at our institution between July 2007 and August 2011 with a minimum follow-up of 6 months. Thirty-four (20 %) underwent concomitant urologic reconstruction at the time of CRS-HIPEC and were matched by disease burden (intraoperative peritoneal cancer index [PCI]) and extent of surgery (ΔPCI) with a cohort of 38 (22.3 %) subjects without genitourinary involvement. The primary end points considered for this analysis included the development of major surgical (Clavien-Dindo Class III-V) complications and overall survival. RESULTS: Median follow-up was 9.4 months. The most commonly performed urologic interventions included partial cystectomy with primary repair in 23 (65.7 %) and segmental ureteral resection and repair in 11 (31.4 %). Patients with genitourinary reconstruction had more total organ involvement (6.5 vs. 4.3, p < 0.001) and more commonly underwent enteric anastomoses (82.4 vs. 57.9 %, p = 0.025). No significant differences were observed with regard to major morbidity, need for transfusion, operative time, intensive care unit admission, or length of stay. Among patients with appendiceal or colonic tumors (n = 46), overall survival was similar between genitourinary reconstruction and matched cohorts: 22.5 versus 15.1 months, respectively (p = 0.66). CONCLUSIONS: Genitourinary reconstruction at the time of CRS-HIPEC occurs more commonly in patients with extensive disease burden undergoing radical debulking, yet does not adversely influence surgical morbidity or survival.

PURPOSE: We assess the risk of urinary incontinence after transurethral prostate resection in patients previously treated with prostate brachytherapy. MATERIALS AND METHODS: A total of 2,495 patients underwent brachytherapy with or without external beam radiation therapy for the diagnosis of prostate cancer between June 1990 and December 2009. Patients who underwent transurethral prostate resection before implantation were excluded from study. Overall 79 patients (3.3%) underwent channel transurethral resection of the prostate due to urinary retention or refractory obstructive urinary symptoms. Correlation analyses were performed using the chi-square (Pearson) test. Estimates for time to urinary incontinence were determined using the Kaplan-Meier method with comparisons using logistic regression and Cox proportional hazard rates. RESULTS: Median followup after implantation was 7.2 years. Median time to first transurethral prostate resection after implantation was 14.8 months. Of the 79 patients who underwent transurethral prostate resection after implantation 20 (25.3%) had urinary incontinence compared with 3.1% of those who underwent implantation only (OR 10.4, 95% CI 6-18, p<0.001). Of the 15 patients who required more than 1 transurethral prostate resection, urinary incontinence developed in 8 (53%) compared with 19% of patients who underwent only 1 resection (OR 4.9, 95% CI 1.5-16, p=0.006). Exclusion of patients who underwent multiple transurethral prostate resections still demonstrated significant differences (18.8% vs 3.1%, OR 7.1, 95% CI 3.6-13.9, p<0.001). Median time from last transurethral prostate resection to urinary incontinence was 24 months. On linear regression analysis, hormone use and transurethral prostate resection after implantation were associated with urinary incontinence (p<0.05). There was no correlation between the timing of transurethral prostate resection after implantation and the risk of incontinence. CONCLUSIONS: Urinary incontinence developed in 25.3% of patients who underwent transurethral prostate resection after prostate brachytherapy. The risk of urinary incontinence correlates with the number of transurethral prostate resections. Patients should be counseled thoroughly before undergoing transurethral prostate resection after implantation.

OBJECTIVE: To characterize the incidence and clinical history of gross haematuria after prostate brachytherapy. To identify treatment risk factors for the development of gross haematuria in this setting. PATIENTS AND METHODS: We reviewed haematuria outcomes collected prospectively in 2454 patients treated with transperineal prostate brachytherapy over a 20-year period at a single institution. Patients were followed for a median of 5.9 years. The association of haematuria with age, pretreatment PSA, ethnicity, clinical tumour stage, Gleason score, prostate volume, isotope (iodine 125 or palladium 103), biologically effective dose (BED), external beam radiation, androgen deprivation, development of urinary retention and occurrence of biochemical failure was investigated. RESULTS: A total of 218 men (8.9%) reported gross haematuria at a median time of 772.2 days after implantation. Haematuria was associated with prostate volume >40 cm(3) (P < 0.01), use of external beam radiation (P < 0.01), Gleason score >7 (P = 0.037), Asian ethnicity (P < 0.001), BED >200 Gy (P = 0.01), and freedom from biochemical failure (P = 0.004). On multivariate analysis, prostate volume >40 cm(3) (P = 0.002), external beam radiation, (P = 0.001), and freedom from biochemical failure (P = 0.035) were predictors of haematuria. CONCLUSIONS: Late gross haematuria was observed in a small proportion of men after brachytherapy and may occur with considerable latency. Larger prostate glands, freedom from biochemical failure and external beam radiation are risk factors.

PURPOSE: The incidental detection of early-stage kidney tumors is increasing in the United States. Nephron-sparing approaches (NS) to managing these tumors are equivalent to radical nephrectomy (RN) in oncologic outcomes and have a decreased impact on renal function. Our objective was to evaluate trends in the use of NS over the past decade and the socioeconomic factors associated with its use. METHODS: The National Cancer Database was queried to identify patients with stage I kidney cancer between 2000 and 2008. Patients were classified by the type of surgery as NS (local destruction and local excision) or RN. Patients were further categorized by age, race, insurance status, and income. Log-binomial regression was used to estimate prevalence ratios (PR) for the proportion of NS to RN according to demographic and socioeconomic characteristics. RESULTS: From 2000 to 2008, there were 142,194 cases of kidney cancer reported to the NCDB. In these cases, 43,034 (30.3 %) patients had NS, and 86,431 (60.78 %) patients had RN. The prevalence of NS increased 10 % per year (PR = 1.10, p < 0.0001)-from 20.0 % in 2000 to 45.1 % in 2008. Older age, lower income, Black race, Hispanic ethnicity, and lack of health insurance were associated with a decreased prevalence of NS. CONCLUSIONS: NS as a treatment for stage I kidney cancer has increased steadily since 2000. Age, racial, and socioeconomic differences may exist in the utilization of NS. Additional analyses, with patient level data, are required to address the independent significance of these variables in an effort to develop strategies to mitigate these potential disparities.

PURPOSE: Two randomized trials published in 2001 provided level 1 evidence for the use of cytoreductive nephrectomy (CyNx) for the treatment of metastatic renal cell carcinoma (mRCC). However, the regulatory approval of vascular endothelial growth factor tyrosine kinase inhibitors (VEGFR-TKI) in 2005 has left an "evidence void" regarding the use of CyNx. We evaluated the patterns in the use of CyNx in the cytokine and VEGFR-TKI eras, and the patient characteristics associated with the use of CyNx. METHODS: The Surveillance, Epidemiology, and End Results registry was used to identify patients with histologically or cytologically confirmed stage IV RCC between 2001 and 2008. Patients were classified as treated during the cytokine (2001-2005) or VEGFR-TKI (2006-2008) eras. A multivariate logistic regression analysis was performed to calculate the odds of undergoing CyNx according to treatment era and socioeconomic characteristics. RESULTS: Overall, 1,112 of 2,448 patients (45%) underwent CyNx. CyNx use remained stable between 2001 and 2005 (50%), but decreased to 38% in 2008. Logistic regression analysis revealed that older age (OR 0.82, 95% CI: 0.68, 0.99), black race (OR 0.64, 95% CI: 0.46, 0.91), Hispanic ethnicity (OR 0.71, 95% CI: 0.54, 0.93), and treatment in the VEGFR-TKI era (OR 0.82, 95% CI: 0.68, 0.99) were independently associated with decreased use of CyNx. CONCLUSIONS: Use of CyNx in the United States has declined in the VEGFR-TKI era. Older patients and minorities are less likely to receive CyNx. Results of ongoing phase III trials are needed to refine the role of this treatment modality.

PURPOSE: Circulating tumor cells are malignant cells in peripheral blood that originate from primary tumors or metastatic sites. The heterogeneous natural history and propensity for recurrence in prostate, bladder and kidney cancers are well suited for improved individualization of care using circulating tumor cells. The potential clinical applications of circulating tumor cells include early diagnosis, disease prediction and prognosis, and selection of appropriate therapies. MATERIALS AND METHODS: The PubMed® and Web of Science® databases were searched using the key words circulating tumor cells, CTC, prostate, kidney, bladder, renal cell carcinoma and transitional cell carcinoma. Relevant articles and references from 1994 to 2011 were reviewed for data on the detection and significance of circulating tumor cells in genitourinary cancer. RESULTS: Technical challenges have previously limited the widespread introduction of circulating tumor cell detection in routine clinical care. Recently novel platforms were introduced to detect these cells that offer the promise of overcoming these limitations. We reviewed the current state of circulating tumor cell capture technologies and their clinical applications for genitourinary cancers. CONCLUSIONS: In genitourinary cancer circulating tumor cell enumeration has been useful for prognosis in patients with castration resistant prostate cancer. Soon characterizing individual circulating tumor cells in blood will serve as a noninvasive real-time liquid biopsy to monitor molecular changes in cancer, allowing clinicians to custom tailor treatment strategies. Circulating tumor cells will serve as a treatment response biomarker. Finally, circulating tumor cell detection promises to assist in the early detection of clinically localized cancers, facilitating curative therapy.

BACKGROUND: Prostate cancer is the most common cancer affecting men in the United States. Management options for localized disease exist, yet an evidence-based criterion standard for treatment still has to emerge. Although 5-year survival rates approach 98%, all treatment options carry the possibility for significant side effects, such as erectile dysfunction and urinary incontinence. It is therefore recommended that patients be actively involved in the treatment decision process. We have developed an Internet/CD-ROM-based multimedia Prostate Interactive Educational System (PIES) to enhance patients' treatment decision making. PIES virtually mirrors a health center to provide patients with information about prostate cancer and its treatment through an intuitive interface, using videos, animations, graphics, and texts. OBJECTIVES: (1) To examine the acceptability and feasibility of the PIES intervention and to report preliminary outcomes of the program in a pilot trial among patients with a new prostate cancer diagnosis, and (2) to explore the potential impact of tailoring PIES treatment information to participants' information-seeking styles on study outcomes. METHODS: Participants (n = 72) were patients with newly diagnosed localized prostate cancer who had not made a treatment decision. Patients were randomly assigned to 3 experimental conditions: (1) control condition (providing information through standard National Cancer Institute brochures; 26%), and PIES (2) with tailoring (43%) and (3) without tailoring to a patient's information-seeking style (31%). Questionnaires were administrated before (t1) and immediately after the intervention (t2). Measurements include evaluation and acceptability of the PIES intervention, monitoring/blunting information-seeking style, psychological distress, and decision-related variables (eg, decisional confidence, feeling informed about prostate cancer and treatment, and treatment preference). RESULTS: The PIES program was well accepted by patients and did not interfere with the clinical routine. About 79% of eligible patients (72/91) completed the pre- and post-PIES intervention assessments. Patients in the PIES groups compared with those in the control condition were significantly more likely to report higher levels of confidence in their treatment choices, higher levels of helpfulness of the information they received in making a treatment decision, and that the information they received was emotionally reassuring. Patients in the PIES groups compared with those in the control condition were significantly less likely to need more information about treatment options, were less anxious about their treatment choices, and thought the information they received was clear (P < .05). Tailoring PIES information to information-seeking style was not related to decision-making variables. CONCLUSIONS: This pilot study confirms that the implementation of PIES within a clinical practice is feasible and acceptable to patients with a recent diagnosis of prostate cancer. PIES improved key decision-making process variables and reduced the emotional impact of a difficult medical decision.

Metastatic prostate cancer (PCa) is one of the leading causes of death from cancer in men. The molecular mechanisms underlying the transition from localized tumor to hormone-refractory metastatic PCa remain largely unknown, and their identification is key for predicting prognosis and targeted therapy. Here we demonstrated that increased expression of a splice variant of the Kruppel-like factor 6 (KLF6) tumor suppressor gene, known as KLF6-SV1, in tumors from men after prostatectomy predicted markedly poorer survival and disease recurrence profiles. Analysis of tumor samples revealed that KLF6-SV1 levels were specifically upregulated in hormone-refractory metastatic PCa. In 2 complementary mouse models of metastatic PCa, KLF6-SV1-overexpressing PCa cells were shown by in vivo and ex vivo bioluminescent imaging to metastasize more rapidly and to disseminate to lymph nodes, bone, and brain more often. Interestingly, while KLF6-SV1 overexpression increased metastasis, it did not affect localized tumor growth. KLF6-SV1 inhibition using RNAi induced spontaneous apoptosis in cultured PCa cell lines and suppressed tumor growth in mice. Together, these findings demonstrate that KLF6-SV1 expression levels in PCa tumors at the time of diagnosis can predict the metastatic behavior of the tumor; thus, KLF-SV1 may represent a novel therapeutic target.

PURPOSE: We describe the safety of sipuleucel-T using an integrated analysis of 4 randomized, controlled studies in patients with prostate cancer. MATERIALS AND METHODS: Adverse events, survival data and laboratory evaluations were examined for common, rare and latent events. RESULTS: In 5% or more of sipuleucel-T cases some adverse events were reported at a rate at least twice that in controls, including chills in 53.1%, pyrexia in 31.3%, headache in 18.1%, myalgia in 11.8%, influenza-like illness in 9.7% and hyperhidrosis in 5.0%. These events generally occurred within 1 day of infusion, were grade 1 or 2 in severity and resolved in 2 days or less. The incidence of serious adverse events reported was 24.0% in sipuleucel-T cases and 25.1% in controls. Grade 3 or greater adverse events were reported within 1 day of infusion in 40 of 601 sipuleucel-T cases (6.7%) and 7 of 303 controls (2.3%). The incidence rate of reported cerebrovascular events was 3.5% for sipuleucel-T cases and 2.6% in controls. CONCLUSIONS: Sipuleucel-T therapy in patients with prostate cancer has a side effect profile that is characterized by mild to moderate, short-term, reversible adverse events. There was no evidence of a treatment related increase in autoimmune complications or secondary malignancies after treatment with sipuleucel-T. Sipuleucel-T can be administered safely in the outpatient setting.

INTRODUCTION: Risk assessment for non-organ-confined prostate cancer (PCa) is important in the surgical planning for radical prostatectomy (RP). Perineural invasion (PNI) on prostate biopsy has been associated with adverse pathological outcomes at prostatectomy. Similarly, the identification of suspected extracapsular extension (ECE) on multiparametric magnetic resonance imaging (mpMRI) has been shown to predict non-organ-confined disease. However, no prior study has compared these factors in predicting adverse pathology at prostatectomy. We evaluated mpMRI ECE and prostate biopsy PNI on multivariable analysis to determine their ability to predict pathological stage at time of RP. METHODS: We retrospectively investigated the prostatectomy database at our institution to identify men who underwent prostate biopsy with pre-biopsy mpMRI and subsequent RP from 2013-2017. Multivariable regression analysis was performed to compare the association of mpMRI ECE (mECE) and PNI on prostate biopsy on the likelihood of finding pT3 disease on pathology post-prostatectomy. RESULTS: Of a total 454 RP between 2013 and 2017, 191 patients met our inclusion criteria. Stage pT2 and pT3+ were found in 120 (62.8%) and 71 (37.2%) patients, respectively. Patients with mECE had 4.84 cumulative odds of worse pathological stage on RP (p=0.045) compared to PNI on biopsy, which showed cumulative odds of 2.25 (p=0.048). When controlling only for those patients without PNI, mECE was still found to be a significant predictor of pT3 disease at RP (p=0.030); however, in patients without mECE, PNI was not significant (p=0.062). CONCLUSIONS: While mECE and biopsy PNI were both associated with worse pathological stage on RP, mECE had significantly higher cumulative odds compared to PNI. The significant predictive ability of mECE adds further clinical value to the use of mpMRI in PCa management. While validation in a larger cohort is required, these factors have important clinical implications with regards to early diagnosis of advanced disease and surgical planning.
RESUMEN
OBJECTIVE: To provide real-time assessment and feedback on the competency of urology residents' surgical skill via mobile applications and examine their feasibility and utility. MATERIALS AND METHODS: Two mobile application-based systems (SIMPL and myTIPreport) were sequentially implemented for the case-by-case assessment of residents' performance of surgical skills at a single institution. Data was collected regarding residents' perception of their feedback pre- and post-implementation of the applications. Faculty were surveyed after their implementation to determine their feasibility and utility. RESULTS: 297 individual evaluations were completed with SIMPL and 822 with myTIPreport over four and eleven months respectively. Post-implementation, residents showed significantly improved perceptions regarding the quantity and personalization of surgical skill feedback (Pâ¯=â¯.043 and .005 respectively). A majority (75%) of the faculty found the mobile applications feasible to use, an improvement compared to prior methods of resident evaluation, and would recommend continued use. CONCLUSION: This study represents the first documented use of real-time surgical competency assessment in urology. The use of mobile applications to evaluate urology residents' surgical competency in clinical practice is both feasible and useful. Their use may allow for more individualized surgical skill teaching during training and for the verification of the surgical skills necessary to practice autonomously.

OBJECTIVE: To apply the American Urogynecological Society (AUGS)/American College of Obstetricians and Gynecologists (ACOG) recommendations of foregoing workup in patients under 50 years of age with less than 25 red cells per high-powered field, to a cohort of asymptomatic microscopic hematuria (AMH) patients, and assess diagnostic accuracy, sensitivity, specificity, positive, and negative predictive value compared to the American Urologic Association (AUA) guidelines. METHODS: Retrospective review of female patients who underwent AMH evaluation from 2012 to 2015. The number of patients who would have avoided workup following the AUGS/ACOG recommendations was determined. Sensitivity, specificity, positive- and negative-predictive value and accuracy of the AUGS/ACOG recommendations compared to AUA guidelines were determined. RESULTS: Six hundred twenty women underwent AMH workup with 265 women undergoing full workup as per the AUA guidelines. Applying the AUGS/ACOG recommendations to this cohort would not have resulted in missed malignant diagnoses. Two tumors were found, both in patients who had undergone complete workup, and for whom AUGS/ACOG recommends workup. Following the AUGS/ACOG recommendations would have avoided workup in 126/620 of all women and 44/265 women who underwent the full AUA workup. In looking at findings of malignancy, the AUGS/ACOG workup had a sensitivity of 100% and a negative predictive value of 100% as compared to the AUA guidelines. CONCLUSION: AUA guidelines may over screen female low risk AMH patients. Extensive workup in a low risk group of female patients does not result in increased cancer diagnoses. Perhaps a more nuanced approach could result in fewer workups without compromising cancer detection.

PURPOSE: We assessed the impact of androgen suppressive therapy on biochemical failure in patients with intermediate risk prostate cancer treated with brachytherapy and external beam irradiation. MATERIALS AND METHODS: From 1994 to 2006, 432 patients with intermediate risk prostate cancer as defined by the National Comprehensive Cancer Network were treated with low dose rate brachytherapy and external beam irradiation with or without 9 months of androgen suppressive therapy. Gleason score was 7 in 76% of cases and prostate specific antigen was 1.4 to 20 ng/ml (median 7.6). Of the patients 350 received androgen suppressive therapy and 82 did not. The biologically effective dose was 142 to 280 Gy2 (median 206). Followup was 23 to 155 months (median 56). RESULTS: The overall 8-year biochemical failure-free rate using the Phoenix definition in patients with vs without androgen suppressive therapy was 92% vs 92% (p = 0.4). The therapy had no significant impact on the biochemical failure-free rate in patients with Gleason score 7 (92% vs 90.5%, p = 0.55), prostate specific antigen 10 to 20 ng/ml (92% vs 100%, p = 0.32), T2b-T2c disease (89.5% vs 97%, p = 0.27) and more than 1 intermediate risk feature (90% vs 100%, p = 0.2). CONCLUSIONS: We addressed the relative importance of radiation dose vs hormonal therapy for intermediate risk prostate cancer. With high biologically effective dose combination treatment androgen suppressive therapy did not have a significant impact on the 8-year biochemical failure-free rate. We question its routine use in this setting.
