Evaluation of the "Teaching Guide for Basic Laparoscopic Skills" as a stand-alone educational tool for hands-on training sessions: a pilot study.

INTRODUCTION AND OBJECTIVES: Standardization of hands-on training (HoT) has profoundly impacted the educational field in the last decade. To provide quality training sessions on a global scale, the European School of Urology Training group developed a teaching guide for tutors in 2015. Our study aims to understand whether this guide alone can provide information enough to match the performance improvement guaranteed by an expert tutor. MATERIAL AND METHODS: 4 randomized groups of participants underwent HoT sessions with different teaching modalities: an expert surgeon (group 1), an expert E-BLUS tutor (group 2), E-BLUS guide alone (group 3), no tutor (group 4). Groups 1 and 2 were respectively provided with two different tutors to avoid biases related to personal tutor ability. Along the training session, each participant could perform five trials on two E-BLUS tasks: Peg transfer and Knot tying. During trials 1 and 5, completion time and number of errors were recorded for analysis with Pi-score algorithm. The average per-group Pi-scores were then compared to measure different performance improvement results. RESULTS: 60 participants from Italy were enrolled and randomized into four groups of 15. Pi-scores recorded on Peg transfer task were 24,6 (group 1), 26,4 (group 2), 42,2 (group 3), 11,7 (group 4). Pi-scores recorded on Knot tying task were 33,2 (group 1), 31,3 (group 2), 37,5 (group 3), 18,6 (group 4). CONCLUSION: Compared to a human tutor, standardized teaching with the EBLUS guide may produce similar performance improvement. This evidence opens doors to automated teaching and to several novelties in hands-on training.

Association between metabolic syndrome and intravesical prostatic protrusion in patients with benign prostatic enlargement and lower urinary tract symptoms (MIPS Study).

OBJECTIVE: To investigate the association between metabolic syndrome (MetS) and morphological features of benign prostatic enlargement (BPE), including total prostate volume (TPV), transitional zone volume (TZV) and intravesical prostatic protrusion (IPP). PATIENTS AND METHODS: Between January 2015 and January 2017, 224 consecutive men aged >50 years presenting with lower urinary tract symptoms (LUTS) suggestive of BPE were recruited to this multicentre cross-sectional study. MetS was defined according to International Diabetes Federation criteria. Multivariate linear and logistic regression models were performed to verify factors associated with IPP, TZV and TPV. RESULTS: Patients with MetS were observed to have a significant increase in IPP (P < 0.01), TPV (P < 0.01) and TZV (P = 0.02). On linear regression analysis, adjusted for age and metabolic factors of MetS, we found that high-density lipoprotein (HDL) cholesterol was negatively associated with IPP (r = -0.17), TPV (r = -0.19) and TZV (r = -0.17), while hypertension was positively associated with IPP (r = 0.16), TPV (r = 0.19) and TZV (r = 0.16). On multivariate logistic regression analysis adjusted for age and factors of MetS, hypertension (categorical; odds ratio [OR] 2.95), HDL cholesterol (OR 0.94) and triglycerides (OR 1.01) were independent predictors of TPV ≥ 40 mL. We also found that HDL cholesterol (OR 0.86), hypertension (OR 2.0) and waist circumference (OR 1.09) were significantly associated with TZV ≥ 20 mL. On age-adjusted logistic regression analysis, MetS was significantly associated with IPP ≥ 10 mm (OR 34.0; P < 0.01), TZV ≥ 20 mL (OR 4.40; P < 0.01) and TPV ≥ 40 mL (OR 5.89; P = 0.03). CONCLUSION: We found an association between MetS and BPE, demonstrating a relationship with IPP.

Sildenafil 25 mg ODT + Collagenase Clostridium hystoliticum vs Collagenase Clostridium hystoliticum Alone for the Management of Peyronie's Disease: A Matched-Pair Comparison Analysis.

INTRODUCTION: The effectiveness of phosphodiesterase type 5 (PDE5) inhibitors over the conservative management of Peyronie's disease (PD) has been widely questioned. AIM: To determine the role of sildenafil 25 mg film formulation twice a day (S25 b.i.d.) in the improvement of curvature after treatment of collagenase of Clostridium hystoliticum (CCH) in penile curvature owing to PD. METHODS: From April 2017 to April 2018, 161 consecutive patients were treated with S25 b.i.d. + CCH or CCH alone. Adjustment variables consisted of age, penile curvature, and the 15-question International Index of Erectile Function (IIEF-15) questionnaire at baseline using 1:1 propensity-score matching. Overall, 50 patients were considered subdivided into the following: 25 patients who received S25 b.i.d. + CCH (group A) and 25 who received CCH alone (group B). Patients received CCH injection using a shortened protocol and vacuum device in both groups. MAIN OUTCOME MEASURE: The primary outcome of the study was the change in penile curvature after treatment, and secondary outcomes were the change in sexual function (IIEF-15) and in the Peyronie's Disease Questionnaire (PDQ) and its subscores, PDQ-PS (psychosexual symptoms), PDQ-PP (penile pain), and PDQ-SB (symptom bother). RESULTS: Overall, mean penile curvature was 47.0° (SD 21.88), the mean IIEF-EF (erectile function) was 23.56 (SD 4.10), and the mean PDQ was 27.06 (SD 13.55). After the treatment, we observed a mean change for penile curvature of 25.6 (SD 9.05) in group A and -25.6 (SD 9.7) in group B (P < .01), for IIEF-EF of 2.28 (SD 2.33) in group A and 1.36 (SD 1.77) in group B (P = .03), for PDQ-PS of -3.04 (SD 2.95) in group A and of -2.12 (SD 2.06) in group B (P = .11), for PDQ-PP of -1.0 (SD 4.48) in group A and of -0.88 (SD 2.04) in group B (P = .60), for PDQ-SB of -5.84 (SD 4.58) in group A and of -4.16 (SD 4.45) in group B (P = .60), and for Female Sexual Function Index of 3.8 (SD 2.45) in group A and of 2.72 (SD 2.28) in group B (P = .14). We found a rate of global satisfaction of 70.83% in group A and of 84.0% in group B (P = .27). CLINICAL IMPLICATIONS: Addition of S25 b.i.d. to CCH is superior to CCH alone for improving penile curvature and erectile function. STRENGTH & LIMITATIONS: This is the first study comparing sildenafil + CCH vs CCH alone for the treatment of PD. Lack of randomization and direct verification of appropriate use of penile modeling could be considered limitations. CONCLUSION: In this study, combination therapy was superior in terms of penile curvature and erectile dysfunction improvement. Cocci A, Cito G, Urzì D, et al.

A phase II, randomized, single-blinded, placebo-controlled clinical trial on the efficacy of Curcumina and Calendula suppositories for the treatment of patients with chronic prostatitis/chronic pelvic pain syndrome type III.

OBJECTIVE: The management of chronic prostatitis/ chronic pelvic pain syndrome type III (CP/CPPS) has been always considered complex due to several biopsychological factors underling the disease. In this clinical study, we aimed to evaluate the efficacy of the treatment with Curcumin and Calendula extract in patients with CP/CPPS III. MATERIAL AND METHODS: From June 2015 to January 2016 we enrolled 60 consecutive patients affected by CP/CPPS III in our institution. Patients between 20 and 50 year of age with symptoms of pelvic pain for 3 months or more before study, a total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score ≥ 15 point and diagnosed with NIH category III. Patients were then allocated to receive placebo (Group A) or treatment (Group B). Treatment consisted of rectal suppositories of Curcumin extract 350 mg (95%) and Calendula extract 80 mg (1 suppository/die for 1 month). Patients of Group B received 1 suppository/die for 1 month of placebo. The primary endpoint of the study was the reduction of NIH-CPSI. The secondary outcomes were the change of peak flow, IIEF-5, VAS score and of premature ejaculation diagnostic tool (PEDT). RESULTS: A total of 48 patients concluded the study protocol. The median age of the all cohort was 32.0 years, the median NIH-CPSI was 20.5, the median IIEF-5 was 18.5, the median PEDT was 11.0, the median VAS score was 7.5 and the median peak flow was 14.0. After 3 months of therapy in group A we observed a significant improvement of NIH-CPSI (-5.5; p < 0.01), IIEF-5 (+ 3.5; p < 0.01), PEDT (-6.5; p < 0.01), peak flow (+2.8; p < 0.01) and VAS (-6.5; p < 0.01) with significant differences over placebo group (all p-value significant). CONCLUSIONS: In this phase II clinical trial we showed the clinical efficacy of the treatment with Curcumin and Calendula in patients with CP/CPPS III. The benefits of this treatment could be related to the reduction of inflammatory cytokines and of inflammatory cells. These results should be confirmed in further studies with greater sample size.

Heme oxygenase levels and metaflammation in benign prostatic hyperplasia patients.

PURPOSE: To investigate the relationship between intra-prostatic levels of heme oxygenase (HO), metaflammation in benign prostatic hyperplasia (BPH) tissue in patients with MetS and moderate-severe lower urinary tract symptoms (LUTS). METHODS: Between January 2012 and June 2013, 132 consecutive patients, who underwent transurethral resection of the prostate for moderate-severe LUTS, secondary to clinical BPH, were enrolled. Prostate samples were investigated for the presence of an inflammatory infiltrate, according to the Irani score, and for HO-1 and HO-2 levels measurements. Patients were evaluated for the presence of metabolic syndrome (MetS) defined by the International Diabetes Federation. RESULTS: We observed that subjects with MetS exhibited greater Irani score (3.0 vs. 2.0; p < 0.05), Irani grade (2.0 vs. 1.0; p < 0.05) and lower value of HO-1 (4.55 vs. 6.01; p < 0.05) and HO-2 (0.81 vs. 2.66; p < 0.05). HO-1 (3.91 vs. 5.67; p < 0.05) and HO-2 (1.06 vs. 1.37; p < 0.05) were significantly reduced in patients with high intra-prostatic inflammation (Irani score ≥4). At the multivariate logistic regression analysis, HO-1 reduction (OR 0.588; p < 0.01), waist circumference (OR 1.09; p < 0.01), triglycerides (OR 1.013; p < 0.05) and HDL (OR 0.750; p < 0.05) were independent predictors of high intra-prostatic inflammation. We also found that HO-1 reduction (OR 0.598; p < 0.01) and the presence of MetS (OR 34.846; p < 0.01) were associated with Irani score ≥4. CONCLUSION: MetS-induced inflammation may play a key role in BPH. In detail, prostate metaflammation is inversely related to intra-prostatic HO-1 levels, serum HDL and positively with triglycerides.

Predicting survival in node-positive prostate cancer after open, laparoscopic or robotic radical prostatectomy: A competing risk analysis of a multi-institutional database.

OBJECTIVES: To investigate cancer-specific mortality and other-cause mortality in prostate cancer patients with nodal metastases. METHODS: The study included 411 patients treated with radical prostatectomy and pelvic lymph node dissection for prostate cancer with lymph node metastases at 10 tertiary care centers between 1995 and 2014. Kaplan-Meier analyses were used to assess cancer-specific mortality-free survival rates at 8 years' follow up in the overall population, and after stratifying patients according to clinical and pathological parameters. Uni- and multivariable competing risk Cox regression analyses were used to assess cancer-specific mortality and other-cause mortality. Finally, cumulative-incidence plots were generated for cancer-specific mortality and other-cause mortality after stratifying patients according to the number of positive lymph nodes and the median age at surgery, according to the competing risks method. RESULTS: Men with prostate-specific antigen ≤40 ng/mL and those with one to three positive lymph nodes showed higher cancer-specific mortality-free survival estimates as compared with their counterparts with prostate-specific antigen >40 ng/mL and >3 metastatic lymph nodes, respectively (all P < 0.001). At multivariable Cox regression analyses, preoperative prostate-specific antigen >40 ng/mL, >3 lymph node metastases and pathological Gleason score 8-10 were all independent predictors of cancer-specific mortality (all P-values ≤0.001). On competing risk analysis, when patients were stratified according to the number of positive lymph nodes (namely, ≤3 vs >3), the 8-year cancer-specific mortality rates were 27.4% versus 44.8% for patients aged <65 years, and 15.2% versus 52.6% for patients aged ≥65 years, respectively. CONCLUSIONS: Three positive lymph nodes represent the best prognostic cut-off in node-positive prostate cancer patients. In those individuals with >3 positive lymph nodes, the overall mortality rate is completely related to prostate cancer in young patients.

Neutrophil to lymphocyte ratio, a biomarker in non-muscle invasive bladder cancer: a single-institutional longitudinal study.

BACKGROUND: Bladder cancer represents one of the most important clinical challenges in urologic practice. In this context, inflammation has an important role in the development and progression of many malignancies. The objective of the present study was to evaluate the prognostic value of pre-treatment Neutrophil to lymphocyte ratio (NLR) on the risk of recurrence and progression in patients with primary non-muscle invasive bladder cancer. MATERIALS AND METHODS: Data obtained from 178 bladder cancer patients who underwent transurethral resection of bladder tumor (TURB) between July 2008 and December 2014 were evaluated prospectively. NLR was obtained from each patient before TURB and defined as the absolute neutrophil count divided by the absolute lymphocyte count. Cox proportional hazards regression model was performed to calculate disease recurrence and progression including NLR. RESULTS: During the follow-up study (median: 53 months), 14 (23.3%) and 44 (37.9%) (p=0.04) patients respectively with NLR<3 and ≥3experienced recurrence and 2 (3.3%) and 14 (11.9%) experienced progression (p=0.06), respectively. At the multivariate Cox regression analysis, NLR ≥3 was associated with worse disease recurrence (HR: 2.84; p<0.01). No association was found regarding disease progression. The 5-year recurrence free survival was 49% and 62% in patients with NLR≥3 and <3 (p<0.01). The 5-year progression free survival was 77% and 93% in patients with NLR≥3 and <3 (p=0.69). CONCLUSION: NLR predicts disease recurrence but not disease progression in NMIBC patients. NLR alterations may depend of tumor inflammatory microenvironment.

Increase of Framingham cardiovascular disease risk score is associated with severity of lower urinary tract symptoms.

OBJECTIVE: To determine the relationship between lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and 10-year risk of cardiovascular disease (CVD) assessed by the Framingham CVD risk score in a cohort of patients without previous episodes of stroke and/or acute myocardial infarction. PATIENTS AND METHODS: From September 2010 to September 2014, 336 consecutive patients with BPH-related LUTS were prospectively enrolled. The general 10-year Framingham CVD risk score, expressed as percentage and assessing the risk of atherosclerotic CVD events, was calculated for each patient. Individuals with low risk had ≤10% CVD risk at 10 years, with intermediate risk 10-20% and with high risk ≥20%. Logistic regression analyses were used to identify variables for predicting a Framingham CVD risk score of ≥10% and moderate-severe LUTS (International Prostate Symptom Score [IPSS] ≥8), adjusted for confounding factors. RESULTS: As category of Framingham CVD risk score increased, we observed higher IPSS (18.0 vs 18.50 vs 19.0; P < 0.05), high IPSS-voiding (6.0 vs 9.0 vs 9.5; P < 0.05) and worse sexual function. Prostate volume significantly increased in those with intermediate- vs low-risk scores (54.5 vs 44.1 mL; P < 0.05). Multivariate logistic regression analysis showed that intermediate- [odds ratio (OR) 8.65; P < 0.01) and high-risk scores (OR 1.79; P < 0.05) were independently associated with moderate-severe LUTS. At age-adjusted logistic regression analysis, moderate-severe LUTS was independently associated with Framingham CVD risk score of ≥10% (OR 5.91; P < 0.05). CONCLUSION: Our cross-sectional study in a cohort of patients with LUTS-BPH showed an increase of more than five-fold of having a Framingham CVD risk score of ≥10% in men with moderate-severe LUTS.

Connections between lower urinary tract symptoms related to benign prostatic enlargement and metabolic syndrome with its components: a systematic review and meta-analysis.

A significant amount of epidemiological evidences have underlined an emerging link between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement a (BPE). We aimed to assess the connections between LUTS and MetS with its components. Meta-analysis were conducted to determine the mean differences (MD) and confidence intervals of IPSS total score, IPSS-voiding, IPSS-storage and prostate volume (PV) in patients with or without MetS. Ln(odds-ratio) were calculated to estimate the risk of having moderate-to-severe LUTS (IPSS ≥ 8). Nineteen studies were identified as eligible for this systematic review, with a total of 18,476 participants, including 5554 (30.06%) with and 12,922 (69.94%) without MetS. Pooled analysis did not demonstrate significant MD of IPSS, IPSS-voiding and IPSS-storage in men with or without MetS but PV was significantly different (MD = 2.18; p = 0.03). Presence of MetS was not significantly associated with moderate-to-severe LUTS (odds ratio = 1.13; p = 0.53) and only altered serum triglycerides and diabetes were associated with this risk. The association between MetS and LUTS/BPE remain unclear and further observational studies in a population with metabolic disorders should be conducted in order to address it's potential role in determining LUTS/BPE.

Emerging links between non-neurogenic lower urinary tract symptoms secondary to benign prostatic obstruction, metabolic syndrome and its components: A systematic review.

We carried out a systematic review in order to determine the connection between lower urinary tract symptoms secondary to bladder outlet obstruction and metabolic syndrome with its components. We searched the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, the Cochrane Database of Systematic Review and Web of Science from their inception until January 2015 to identify all eligible studies on the effect of metabolic syndrome (or component factors) on the presence or severity of lower urinary tract symptoms/bladder outlet obstruction in men. This analysis was carried out according to the STrengthening the Reporting of OBservational studies in Epidemiology guidelines. In total, 19 studies were identified as eligible for this systematic review. The quality assessment score was ≥50% in more than half of the studies (11/19). The evidence synthesis showed a positive association between metabolic syndrome, number of components and lower urinary tract symptoms/bladder outlet obstruction. In particular, the major endocrine aberrations of this connection are central obesity and hypertriglyceridemia. The links between insulin resistance and lower urinary tract symptoms/bladder outlet obstruction should be better investigated. Ethnic disparities in all examined studies showed a different impact of metabolic syndrome on lower urinary tract symptoms/bladder outlet obstruction severity and such influence still remain unclear. The relationship between metabolic syndrome and lower urinary tract symptoms/bladder outlet obstruction open the way for introducing physical activity and diet as recognized first-line interventions for treating lower urinary tract symptoms. However, this connection should be investigated in two different ethnic cohorts (i.e. Asian vs Caucasian) in order to better understand the impact of ethnic disparities on metabolic syndrome and lower urinary tract symptoms/bladder outlet obstruction severity.

Tailored treatment including radical prostatectomy and radiation therapy + androgen deprivation therapy versus exclusive radical prostatectomy in high-risk prostate cancer patients: results from a prospective study.

PURPOSE: To evaluate outcomes of patients with high risk prostate cancer (PCa) who underwent radical prostatectomy (RP) in a context of a multidisciplinary approach including adjuvant radiation (RT) + androgen deprivation therapy (ADT). MATHERIALS AND METHODS: 244 consecutive patients with high risk localized PCa underwent RP and bilateral extended pelvic lymph node dissection at our institution. Adjuvant RT + 24 months ADT was carried out in subjects with pathological stage ≥ T3N0 and/or positive surgical margins or in patients with local relapse. RESULTS: After a median follow-up was 54.17 months (range 5.4-117.16), 13 (5.3%) subjects had biochemical progression, 21 (8.6%) had clinical progression, 7 (2.9%) died due to prostate cancer and 15 (6.1%) died due to other causes. 136 (55.7%) patients did not receive any adjuvant treatment while 108 (44.3%) received respectively adjuvant or salvage RT+ADT. Multivariate Cox proportional hazard analysis showed that pre-operative PSA value at diagnosis is a significant predictive factor for BCR (HR: 1.04, p < 0.05) and that Gleason Score 8-10 (HR: 2.4; p < 0.05) and PSMs (HR: 2.01; p < 0.01) were significant predictors for clinical progression. Radical prostatectomy group was associated with BPFS, CPFS, CSS and OS at 5-years of 97%, 90%, 95% and 86% respectively, while adjuvant radiation + androgen deprivation therapy group was associated with a BPFS, CPFS and CSS at 5-years of 91%, 83%, 95% and 88%, without any statistical difference. CONCLUSIONS: Multimodality tailored treatment based on RP and adjuvant therapy with RT+ADT achieve similar results in terms of OS after 5-years of follow-up.

Pharmacotherapeutic management of lower urinary tract symptoms in Multiple Sclerosis patients.

INTRODUCTION: Multiple Sclerosis (MS) manifests with a plethora of signs and symptoms affecting brain structures and spinal pathways. The multitude of lesions in MS patients makes difficult to establish the relative role of each of them to lower urinary tract symptoms (LUTS). Generally, the subcortical white-matter lesions result in detrusor overactivity, whilst lesions of the spinal cord result in the combined occurrence of detrusor overactivity and detrusor-sphincter dyssynergia (DSD). It has been estimated that 80-90% of patients with MS will suffer from some form of LUTS over the course of the disease. Among LUTS, the most reported is detrusor overactivity which includes urinary urgency, frequent urination, nocturia, and urge urinary incontinence. AREAS COVERED: The authors review the management of lower urinary tract symptoms in MS patients providing their expert opinions on the subject matter. EXPERT OPINION: LUTS affect the quality of life substantially and are associated with a significantly increased mortality. The adequate management is an important challenge for both patients and caregivers with a multidisciplinary approach likely necessary.

Adherence to Mediterranean diet and prostate cancer risk in Sicily: population-based case-control study.

Prostate cancer (PCa) is the second most frequently diagnosed cancer and the sixth leading cause of death from cancer worldwide. Countries following a Mediterranean-type dietary pattern, has been reported to have lower PCa incidence and mortality compared with other European regions. A population-based case-control study has been conducted from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy. A total of 118 PCa and 238 population-based controls were collected. Controls had significantly higher adherence to the Mediterranean diet, which was evident for several subgroups (including age groups, overweight and obese men, current smokers, alcohol intake, low and medium physical activity levels). PCa cases were found to consume lower amount of vegetables (223 g/d vs. 261 g/d; p = 0.001), legumes (34.26 g/d vs. 53.55 g/d; p = 0.003), and fish (47.75 g/d vs. 58.3 g/d) than controls; other differences emerged were related to alcohol intake (12.37 g/d vs 5.07 g/d; p < 0.01), cereals (254.06 g/d vs.235.94 g/d; p < 0.001), dairy (196 g/d vs. 166 g/d; p < 0.001), and meat consumption (98.09 g/d vs. 70.15 g/d; p < 0.001). However, no statistically significant differences between cases and controls were found regarding fruit, legumes, and olive oil consumption. The Mediterranean diet score was inversely associated with lower likelihood of having PCa in a linear manner (odds ratio [OR]: 0.86 [95% CI 0.77-0.96]). Specifically, individuals in the highest group of adherence had 78% less likelihood of have PCa and 14% less likelihood for each point increase of the score. The model adjusted for total polyphenol intake showed still a significant inverse association between adherence to the Mediterranean diet and PCa, but the relation was no more linear and not significant for one-point increase of the score (OR: 0.88 [95% CI 0.77-1.01]). In our cohorts of Italian men, we observed that high adherence to the Mediterranean diet was inversely associated with likelihood of having PCa cancer.

Prevalence of intratubular germ cell neoplasia and multifocality in testicular germ cell tumors ≤ 2 cm: relationship with other pathological features.

INTRODUCTION: The aim of this study was to determine the prevalence of TIN and multifocality in men undergoing radical orchiectomy for testicular germ cell tumor (TGCT), and among those with a main tumor size ≤ 2 cm, potentially eligible for testis-sparing surgery. PATIENTS AND METHODS: Orchiectomy specimens from 126 consecutive patients treated for TGCT tumor between 2003 and 2012 were included. Multifocality was defined as a distinct tumor focus with a diameter ≥ 1 mm separable from the main tumor mass. Uni- and multivariate logistic regression was performed to identify the association between pathological variables and multifocality and to identify variables for predicting clinical stage II to III and pathological stage ≥ pT2. RESULTS: Of the 126 patients, 103 (82.0%) had clinical stage I cancer at presentation and 23 (18.0%) had clinical stage II to III. The median size of the primary tumor mass was 3.7 cm (range, 0.5-12 cm) in multifocality and 3.0 cm (range, 0.6-8.0 cm) in monofocality, respectively (P < .05). The prevalence of multifocality and TIN was lower in the presence of a smaller main tumor mass (≤ 1 cm) compared with tumors 1.1 to 2.0 cm (P < .05), and increased when the index mass tumor diameter was ≥ 2 cm (P trend < .05). No association was found between tumor histology and multifocality (P = .95) or TIN (P = .54) using the χ(2) test. CONCLUSION: The prevalence of multifocality and TIN was decreased in smaller tumors (≤ 1 cm) and increased when the index mass tumor diameter was ≥ 1.1 cm.

[5ARI and PSA: evidences]. / 5ARI e PSA: evidenze.

OBJECTIVE: The 5alpha-reductase inhibitors (5ARIs) represent a valid therapeutic option in the long-term treatment of benign prostatic hyperplasia (BPH). One of the most debated topics is the interpretation of the variation of the serum PSA during treatment with 5ARIs. The objective of this review was to analyze the change in serum PSA levels over time and to evaluate its sensitivity and specificity in the screening for prostate cancer (CaP) during treatment. METHODS: An extensive search using PubMed and Scopus was performed including the following key words: "5ARI", "finasteride", "dutasteride", "prostate cancer", "benign prostatic hyperplasia", "PSA", "kinetics", "PSA derivatives". RESULTS: The reduction of serum PSA during treatment with 5ARIs can be observed up to 48 months after the beginning of the therapy. This category of drugs seems to improve the diagnostic performance of PSA in screening CaP. On the other hand, there is a reduction of the diagnosis of indolent cancers. Any increase in PSA from nadir should be considered suspicious for malignancy. However, if the choice of a biopsy depended only on an increase of the values of serum PSA, a variable percentage of potentially aggressive tumors could not be diagnosed. Therefore, it is important to consider in the clinical and diagnostic follow-up other factors such as digital rectal examination, age, family history of CaP and imaging techniques. CONCLUSIONS: 5-ARIs have a positive impact on the specificity of PSA but they must not be the only tool that can identify CaPs with poor prognosis.

Percentage of cancer involvement in positive cores can predict unfavorable disease in men with low-risk prostate cancer but eligible for the prostate cancer international: active surveillance criteria.

OBJECTIVES: To identify predictive factors of unfavorable disease and of biochemical failure in patients treated with radical prostatectomy but eligible for active surveillance (AS) according to Prostate Cancer Research International: Active Surveillance (PRIAS) criteria. We aimed to introduce and validate the percentage of cancer involvement in positive cores (CIPC) as potential worse predictive factor. METHODS: From January 2002 to December 2007, 750 consecutive subjects underwent radical prostatectomy at a single institution. We identified 147 (19.05%) patients who were eligible for AS based on PRIAS criteria: clinical stage T1c or T2 disease, prostate-specific antigen level of ≤ 10 ng/ml, Gleason score ≤ 6, prostate-specific antigen-D of<0.2 ng/ml(2), and fewer than 3 positive biopsy cores. CIPC was included in the analysis. RESULTS: Of the 147 patients, 95 (66.43%) patients had favorable disease, whereas 48 (33.57%) had unfavorable disease. In multivariate logistic regression, maximum cancer length (odds ratio 12.52, P<0.01) and CIPC (odds ratio 1.70, P<0.01) represented independent predictors of unfavorable prostate cancer. The area under the receiver operating characteristics curve analysis revealed significantly higher performance after including CIPC to the PRIAS criteria (0.61 vs. 0.94, P<0.01). A cutoff of 0.4mm of CIPC was set to predict unfavorable disease with 93% specificity, 76% sensibility, and 87% accuracy based on the receiver operating characteristics curve analysis. Finally, the 3- and 5-years biochemical recurrence (BCR)-free survival were significantly lower in subjects with CIPC ≥ 0.4mm, 88.4 % and 81.0% vs. 97.8% and 95.7%, respectively (P< 0.01). CONCLUSIONS: Our findings suggest that the inclusion of CIPC to the prostate biopsy features could be helpful to avoid misclassification in patients eligible for AS according to the PRIAS criteria.

Multifocality in testicular germ cell tumor (TGCT): what is the significance of this finding?

PURPOSE: The aim of the study is to determine the association between multifocality and the pathological features of testicular germ cell tumors and its clinical implication. METHODS: Orchiectomy specimens from 254 consecutive patients with testis cancer between 2003 and 2013 were included. Multifocality was defined as a distinct tumor focus of cluster of malignant cells > 0.5 mm and separable from the main tumor mass. Univariate logistic regression analysis was performed to evaluate the association between multifocality and other pathological features. Multivariate logistic regression analyses were carried out to identify potential predictive factors of multifocality for clinical stages II-III and the pathological stage ≥ pT2. RESULTS: Median patient age was 33 years (range 19-70). Multifocality was identified in 58 (22.83 %) orchiectomy specimens. Subjects with multifocality had larger primary tumor lesions (3.7 vs. 3.0 cm; p < 0.05). No association was found between histology and multifocality (p = 0.95). On univariate logistic regression analysis, multifocality was not significantly associated with all pathological features. On multivariate logistic regression analysis, multifocality was not demonstrated to be an adverse pathological feature of clinical stages II-III (p = 0.23) or pathological stage ≥ pT2 (p = 0.30) when included in a model with tumor size ≥ 4 cm and rete testis invasion in seminoma tumor and neither of clinical stages II-III (p = 0.36) or pathological stage ≥ pT2 (p = 0.20) when included in a model with lymphovascular invasion and percentage of embrional cancer ≥ 50 % in non-seminoma ones. CONCLUSION: Multifocality should not be considered an adverse pathological feature in patients with testis cancer, independently to histological subtypes.

Neutrophil to lymphocyte ratio, a biomarker in non-muscle invasive bladder cancer: a single-institutional longitudinal study

ABSTRACT Background: Bladder cancer represents one of the most important clinical challenges in urologic practice. In this context, inflammation has an important role in the development and progression of many malignancies. The objective of the present study was to evaluate the prognostic value of pre-treatment Neutrophil to lymphocyte ratio (NLR) on the risk of recurrence and progression in patients with primary non-muscle invasive bladder cancer. Materials and Methods: Data obtained from 178 bladder cancer patients who underwent transurethral resection of bladder tumor (TURB) between July 2008 and December 2014 were evaluated prospectively. NLR was obtained from each patient before TURB and defined as the absolute neutrophil count divided by the absolute lymphocyte count. Cox proportional hazards regression model was performed to calculate disease recurrence and progression including NLR. Results: During the follow-up study (median: 53 months), 14 (23.3%) and 44 (37.9%) (p=0.04) patients respectively with NLR<3 and ≥3experienced recurrence and 2 (3.3%) and 14 (11.9%) experienced progression (p=0.06), respectively. At the multivariate Cox regression analysis, NLR ≥3 was associated with worse disease recurrence (HR: 2.84; p<0.01). No association was found regarding disease progression. The 5-year recurrence free survival was 49% and 62% in patients with NLR≥3 and <3 (p<0.01). The 5-year progression free survival was 77% and 93% in patients with NLR≥3 and <3 (p=0.69). Conclusion: NLR predicts disease recurrence but not disease progression in NMIBC patients. NLR alterations may depend of tumor inflammatory microenvironment.

Tailored treatment including radical prostatectomy and radiation therapy + androgen deprivation therapy versus exclusive radical prostatectomy in high-risk prostate cancer patients: results from a prospective study

Purpose To evaluate outcomes of patients with high risk prostate cancer (PCa) who underwent radical prostatectomy (RP) in a context of a multidisciplinary approach including adjuvant radiation (RT) + androgen deprivation therapy (ADT). Matherials and Methods 244 consecutive patients with high risk localized PCa underwent RP and bilateral extended pelvic lymph node dissection at our institution. Adjuvant RT + 24 months ADT was carried out in subjects with pathological stage ≥ T3N0 and/or positive surgical margins or in patients with local relapse. Results After a median follow-up was 54.17 months (range 5.4-117.16), 13 (5.3%) subjects had biochemical progression, 21 (8.6%) had clinical progression, 7 (2.9%) died due to prostate cancer and 15 (6.1%) died due to other causes. 136 (55.7%) patients did not receive any adjuvant treatment while 108 (44.3%) received respectively adjuvant or salvage RT+ADT. Multivariate Cox proportional hazard analysis showed that pre-operative PSA value at diagnosis is a significant predictive factor for BCR (HR: 1.04, p < 0.05) and that Gleason Score 8-10 (HR: 2.4; p<0.05) and PSMs (HR: 2.01; p < 0.01) were significant predictors for clinical progression. Radical prostatectomy group was associated with BPFS, CPFS, CSS and OS at 5-years of 97%, 90%, 95% and 86% respectively, while adjuvant radiation + androgen deprivation therapy group was associated with a BPFS, CPFS and CSS at 5-years of 91%, 83%, 95% and 88%, without any statistical difference. Conclusions Multimodality tailored treatment based on RP and adjuvant therapy with RT+ADT achieve similar results in terms of OS after 5-years of follow-up. .
