RESUMO

Prostate cancer (PCa) is a prevalent malignancy affecting men worldwide, and plant-based diets have been widely advocated for their health benefits. The aim of this study was to test the association between general, healthy, and unhealthy pro-vegetarian plant-based diets and PCa severity on 118 consecutive patients undergoing prostatectomy in a university hospital in Italy. Food frequency questionnaires were used to calculate scores for dietary patterns. Multivariate logistic regression analyses were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) to test the associations. A general plant-based diet was not associated with cancer severity, while patients reporting a higher adherence to a healthy plant-based diet were less likely to have a more severe PCa (for medium/high vs. low-risk PCa, OR = 0.27, 95% CI: 0.08, 0.88; for high vs. medium/low-risk PCa, OR = 0.09, 95% CI: 0.02, 0.39). Patients resulting in higher adherence to an unhealthy plant-based diet were more likely to be diagnosed with more severe PCa (OR = 6.15, 95% CI: 1.70, 22.24). In conclusion, plant-based dietary patterns may have a different impact on PCa severity depending on the quality of the foods included.

RESUMO

We aimed to analyze the association between CYP7B1 and prostate cancer, along with its association with proteins involved in cancer and metabolic processes. A retrospective analysis was performed on 390 patients with prostate cancer (PC) or benign prostatic hyperplasia (BPH). We investigated the interactions between CYP7B1 expression and proteins associated with PC and metabolic processes, followed by an analysis of the risk of biochemical recurrence based on CYP7B1 expression. Of the 139 patients with elevated CYP7B1 expression, 92.8% had prostate cancer. Overall, no increased risk of biochemical recurrence was associated with CYP7B1 expression. However, in a non-diabetic subgroup analysis, higher CYP7B1 expression indicated a higher risk of biochemical recurrence, with an HR of 1.78 (CI: 1.0-3.2, p = 0.05). PC is associated with elevated CYP7B1 expression. In a subgroup analysis of non-diabetic patients, elevated CYP7B1 expression was associated with an increased risk of biochemical recurrence, suggesting increased cancer aggressiveness.

RESUMO

In multiple myeloma (MM), circulating tumor plasma cells (CTPCs) are an emerging prognostic factor, offering a promising and minimally invasive means for longitudinal patient monitoring. Recent advances highlight the complex biology of plasma cell trafficking, highlighting the phenotypic and genetic signatures of intra- and extra-medullary MM onset, making CTPC enumeration and characterization a new frontier of precision medicine for MM patients, requiring novel technological platforms for their standardized and harmonized detection. Dielectrophoresis (DEP) is an emerging label-free cell manipulation technique to separate cancer cells from healthy cells in peripheral blood samples, based on phenotype and membrane capacitance that could be successfully tested to enumerate and isolate CTPCs. Herein, we summarize preclinical data on DEP development for CTPC detection, as well as their clinical and research potential.

RESUMO

OBJECTIVE: To study the association between insulin receptors (isoforms α and ß), insulin growth factor-1 (IGF1) and serine/arginine splicing factor 1 (SRSF-1) in patients with prostate cancer (PC) and diabetes. MATERIALS AND METHODS: We retrospectively analyzed data from 368 patients who underwent surgery for PC or benign prostatic hyperplasia (BPH) between 2010 and 2020 at the Department of Urology, University of Catania. Tissue microarray slides were constructed and they were stained for androgen receptor (AR), insulin receptor-α and -ß, IGF1 (IGF1-R), Ki-67, and prostate specific membrane antigen (PSMA) expression using validated score. RESULTS: The final cohort was represented by 100 patients with BPH and 268 with PC, with a median age of 68 years. We found that SRSF-1 expression was associated with AR (odds ratio [OR]: 1.66), PSMA (OR: 2.13), Ki-67 (OR: 5.99), insulin receptor (IR)-α (OR: 2.38), IR-ß (OR: 3.48), IGF1-R (OR: 1.53), and microvascular density (MVD) was associated with PSMA (OR: 3.44), Ki-67 (OR: 2.23), IR-α (OR: 2.91), IR-ß (OR: 3.02), IGF1-R (OR: 2.95), and SRSF-1 (OR: 2.21). In the sub cohort of PC patients, we found that SRSF-1 expression was associated with AR (OR: 2.34), Ki-67 (OR: 6.77), IR-α (OR: 2.7), and MVD (OR: 1.98). At the Kaplan-Meier analysis, SRSF-1+ patients had worse 5- and 9-year biochemical recurrence (36% and 6%) respect to SRSF-1- (67% and 7%; p < .01) and similarly MVD+ patients (44% and 7%) respect to MVD- (64% and 8%; p < .01). Restricting the analysis only in patients with PC and diabetes, we found that SRSF-1+ was associated with Ki-67+ (OR: 8.75; p < .05) and MVD+ (OR: 7.5; p < .05). CONCLUSIONS: PC exhibits widespread heterogeneity in protein expression. In particular, the expressions of the SRSF-1 protein and of the MVD are associated with a worse prognosis and in particular with a greater cell proliferation. These results, although preliminary, may offer new future scientific insights with the aim of highlighting possible genetic alterations linked to a greater expression of SRSF-1 and associated with a worse prognosis.

RESUMO

PURPOSE: Few tools are available to predict uretero-lithotripsy outcomes in patients with ureteral stones. Aim of our study was to develop a nomogram predicting the probability of stone free rate in patients undergoing semi-rigid uretero-lithotripsy (ULT) for ureteral stones. METHODS: From January 2014 onwards, patients undergoing semi-rigid Ho: YAG laser uretero-lithotripsy for ureteral stones were prospectively enrolled in two centers. Patients were preoperatively evaluated with accurate clinical history, urinalysis and renal function. Non-contrast CT was used to define number, location and length of the stones and eventually the presence of hydronephrosis. A nomogram was generated based on the logistic regression model used to predict ULT success. RESULTS: Overall, 356 patients with mean age of 54 years (IQR 44/65) were enrolled. 285/356 (80%) patients were stone free at 1 month. On multivariate analysis single stone (OR 1.93, 95% CI 1.05-3.53, p = 0.034), stone size (OR 0.92, 95% CI 0.87-0.97, p = 0.005), distal position (OR 2.12, 95% CI 1.29-3.48, p = 0.003) and the absence of hydronephrosis (OR 2.02, 95% CI 1.08-3.78, p = 0.029) were predictors of success and these were used to develop a nomogram. The nomogram based on the model presented good discrimination (area under the curve [AUC]: 0.75), good calibration (Hosmer-Lemeshow test, p > 0.5) and a net benefit in the range of probabilities between 15 and 65%. Internal validation resulted in an AUC of 0.74. CONCLUSIONS: The implementation of our nomogram could better council patients before treatment and could be used to identify patients at risk of failure. External validation is warranted before its clinical implementation.

RESUMO

The objective of the current research was to explore the potential prognostic value of readily available clinical and pathologic variables in bladder cancer. The novel association found between cholesterol levels and prognosis may provide the rationale for exploring novel treatments. Patients included had histologically confirmed urothelial bladder cancer and were treated with at least 3 cycles of cisplatin-based neoadjuvant chemotherapy before radical cystectomy with lymphadenectomy. A total of 245 patients at low, intermediate and high risk, presenting with 0-1, 2 or 3-4 risk factors, including positive lymph nodes, Hb <12.8, NLR ≥2.7 and cholesterol levels ≥199, were included. Five-year cancer-specific survival rate was 0.67, 0.78 and 0.94 at high, intermediate and low risk, respectively. Total cholesterol levels at the time of cystectomy may represent a commonly assessable prognostic factor and may be incorporated in a clinically meaningful risk-group classification model.


Lay abstract This present study assessed a large group of patients with urothelial bladder cancer treated with chemotherapy followed by radical cystectomy, to capture the predictive power of commonly collected clinical, pathological and biochemical factors. The design of the study highlighted that higher cholesterol levels at the time of cystectomy were associated with shorter cancer-specific survival. This finding suggests that high blood-cholesterol levels truly have a negative influence on surviving cancer. In conclusion, total cholesterol levels at the time of cystectomy may represent a commonly assessable prognostic factor and could be incorporated into a clinically meaningful and valuable risk-group classification model.

RESUMO

The treatment of male lower urinary tract symptoms (LUTS) due to benign prostatic obstruction represents one of the major interesting aspects in urological clinical practice. Although transurethral resection of the prostate is still considered the surgical gold standard for treatment of benign prostatic hyperplasia with prostate volume <80 mL, various minimally invasive surgical treatments (MITs) have been developed to overcome the limitations of the "conventional" surgery. To date, there are no validated tools to evaluate the surgical outcomes of MITs; however, in the past, BPH-6 has been used for this purpose. In this systematic review, we evaluated the efficacy and safety of MITs according to BPH-6 score system. We focused our attention on MITs based on mechanical devices (prostatic urethral lift and the temporary implantable nitinol device) and techniques for prostate ablation (image guided robotic waterjet ablation and convective water vapor energy ablation). Evidence shows that MITs are capable of leading to an improvement in LUTS without having an overwhelming impact on complications and are a valid alternative to other treatments in patients who wish to preserve their sexual function or in case of inapplicability of conventional surgery. However, comparative studies between these techniques are still missing.

RESUMO

The aim of the present study was to evaluate the size of the penis in flaccidity and in erection of Italian men. A total of 4,685 men living in Italy and who have been visited at the Italian urology operating units were involved in the study between January 2019 and January 2020. Each patient was given details on how to measure their penis (erect length and circumference) in flaccidity and in erection, from the lower base to the distal penile tip. Mean (standard deviation [SD]) flaccid penis length was 9.47 (2.69), mean (SD) flaccid penis circumference was 9.59 (3.08), mean (SD) erect penis length was 16.78 (2.55) and mean (SD) erect penis circumference was 12.03 (3.82). At the linear regression analysis, height was associated with flaccid penis length (ß = 0.04; p-value = .01), and erect penis length was (ß = 0.05; p-value < .01) and erect penis circumference was (ß = 0.06; p-value < .01). Height is proportional to the length of the penis in flaccidity and in erection, and to the circumference in erection. The increase in BMI leads to a reduction in the length of the erect penis, as well as weight gain reduces the length of the flaccid penis.

RESUMO

In the present study, we aimed to evaluate the association between asexual trait, erectile dysfunction (ED) and porn addiction in a community sample of young men. Between August 2019 and October 2019, a total of 559 young male adults were subjected to an online survey sponsored by social networks with the aim of assessing their sexual habits. The following questionnaires were administered: The International Index of Erectile Function (IIEF-5), Masturbation Erection index (MEI), Pornography Craving Questionnaire (PCQ) and Asexuality Identification Scale (AIS). The overall rate of ED according to IIEF-5 was 26.0% (165/478), the rate of ED according to MEI was 16.9% (81/478) and the rate ED in patients with AIS ≥23 indicating asexual trait was 10.0% (48/478). We found that IIEF-5 was positively associated with MEI (b = 0.32; p < .01) and negatively with AIS (b = -0.36; p < .01) and MEI was negatively associated with AIS (b = -0.36; p < .01). We found that MEI (odds ratio [OR]: 0.86; p < .01) and IIEF-5 (OR: 0.89; p < .01) were inversely associated with asexual trait. The presence of asexual trait can hide a greater risk of finding ED both in intercourse or masturbation. These results should be taken into consideration during the general assessment of the patient with sexual problems.

RESUMO

PURPOSE: The aim of this systematic review is to summarize the contemporary literature on aquablation and evaluate its safety and efficacy for the treatment of symptomatic BPE. EVIDENCE ACQUISITION: A systematic search of English language literature was performed using the PubMed-MEDLINE and Web of Science libraries up to 24 July 2019 by combining PICO (patient population, intervention, comparison, and outcome) terms. We retrieved 16 studies, including 446 patients treated with aquablation eligible for data extraction and analysis. Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were followed. EVIDENCE SYNTHESIS: We identified a randomized controlled trial (RCT) comparing aquablation to transurethral resection of the prostate (TURP) with 6-month, 1-year, and 2-year outcomes, three single-center and single-arm studies, three multicenter and single-arm studies, and five subgroup analyses. Aquablation significantly improved International Prostate Symptom Score (IPSS), IPSS-quality of life (IPSS-QoL), maximum urinary flow rate (Qmax) and post void residual (PVR) from baseline to last follow-up in all prospective studies. At 2-year follow-up, aquablation showed non-inferior symptom relief compared to TURP, with a lower risk of anejaculation favoring aquablation and no significant differences regarding Clavien-Dindo events. Although a significant hemoglobin drop was reported in all aquablation single-arm studies and when compared to TURP, it did not translate into increased transfusion rates. CONCLUSIONS: Data from the WATER trial demonstrates that aquablation is comparable to TURP in effectively improving symptom scores and functional parameters related to BPE and bladder outlet obstruction. The evidence provided supports the safety of aquablation assessed by procedure-related adverse events.

RESUMO

The COVID-19 pandemic has radically changed the way of life around the World. The state of alarm has forced the population to stay at home, radically changing both interpersonal and partner relationships; work at home, social distancing, the continued presence of children at home, fear of infection and not being able to physically meet with others have changed most people's sexual habits. We conducted a review by exploring the impact of the COVID-19 pandemic on sexual behavior in the population from three different countries: Iran, Italy and Spain from each country's perspective. The impact of the coronavirus will be very important in the sexual life of the people and we will attend in the next months or years, to some changes in the relationships at all the levels. The pandemic will negatively affect sexual behaviors due to multiple contact restrictions. In the future, we will be able to assess these effects in more detail.

RESUMO

INTRODUCTION: Medical treatment of Peyronie's disease (PD) in terms of intralesional therapy is still a matter of debate. AIM: To compare the efficacy of different classes of intralesional therapy with a network meta-analysis (NMA) method. METHODS: The search was conducted using documents published in PubMed, Scopus, and Web of Science databases until September 30, 2017. We included randomized controlled trials comparing at least 1 intralesional therapy with a placebo therapy or with another drug for the treatment of PD. All intralesional therapies have been considered: collagenase Clostridium histolyticum (CCH), hyaluronic acid, verapamil, and interferon α-2b. MAIN OUTCOME MEASURE: Outcomes of the study are the mean change in penile curvature (PC) and in erectile function (EF) assessed with the International Index of Erectile Function questionnaire. RESULTS: In total, 8 comparisons matched with the inclusion criteria, which includes 1,050 patients. With regard to PC (degree) improvement, hyaluronic acid and verapamil showed worse outcomes when compared with CCH (-6.66 and -2.30) and interferon α-2b (-6.75 and -2.38). When considering improvement in EF, hyaluronic acid, verapamil and interferon α-2b showed a slight increase in mean change when compared with CCH (+2.39, +1.77, and +0.65). Moreover, verapamil and interferon α-2b showed slightly worse mean change in comparison to hyaluronic acid (+0.62 and +1.74), whereas interferon α-2b was worse than verapamil (-1.12). CLINICAL IMPLICATIONS: Based on this NMA, empirical therapy for PD should be avoided to offer the patients the best treatment in terms of level of evidence. STRENGTHS & LIMITATIONS: In this NMA, we have provided, for the first time, evidence of the efficacy between different intralesional therapies for the treatment of PD. We were not able to compare all specific outcomes (ie, pain, plaque size, patient satisfaction) of PD, because of the lack of homogeneity across relevant studies. Moreover, because of the few included studies, a meta-regression analysis of predictive factors of treatment response was not calculated. CONCLUSION: This is the first meta-analysis comparing all available intralesional treatments for PD. CCH and interferon α-2b showed the best outcome in terms of PC, whereas hyaluronic acid was most efficient in relation to EF. Russo GI, Cacciamani G, Cocci A, et al.

RESUMO

PURPOSE: The body mass index (BMI) may be associated with an increased incidence and aggressiveness of urological cancers. In this study, we aimed to evaluate the impact of the BMI on survival in patients with T1G3 non-muscle-invasive bladder cancer (NMIBC). METHODS: A total of 1155 T1G3 NMIBC patients from 13 academic institutions were retrospectively reviewed and patients administered adjuvant intravesical Bacillus Calmette-Guérin (BCG) immunotherapy with maintenance were included. Multivariable Cox regression analysis was performed to identify factors predictive of recurrence and progression. RESULTS: After re-TURBT, 288 patients (27.53%) showed residual high-grade NMIBC, while 867 (82.89%) were negative. During follow-up, 678 (64.82%) suffered recurrence, and 303 (30%) progression, 150 (14.34%) died of all causes, and 77 (7.36%) died of bladder cancer. At multivariate analysis, tumor size (hazard ratio [HR]:1.3; p = 0.001), and multifocality (HR:1.24; p = 0.004) were significantly associated with recurrence (c-index for the model:55.98). Overweight (HR: 4; p < 0.001) and obesity (HR:5.33 p < 0.001) were significantly associated with an increased risk of recurrence. Addition of the BMI to a model that included standard clinicopathological factors increased the C-index by 9.9. For progression, we found that tumor size (HR:1.63; p < 0.001), multifocality (HR:1.31; p = 0.01) and concomitant CIS (HR: 2.07; p < 0.001) were significant prognostic factors at multivariate analysis (C-index 63.8). Overweight (HR: 2.52; p < 0.001) and obesity (HR: 2.521 p < 0.001) were significantly associated with an increased risk of progression. Addition of the BMI to a model that included standard clinicopathological factors increased the C-index by 1.9. CONCLUSIONS: The BMI could have a relevant role in the clinical management of T1G3 NMIBC, if associated with bladder cancer recurrence and progression. In particular, this anthropometric factor should be taken into account at initial diagnosis and in therapeutic strategy decision making.

RESUMO

Glycopeptide enrichment can be a strategy to allow the detection of peptides belonging to low abundance proteins in complex matrixes such as blood serum or plasma. Though several glycopeptide enrichment protocols have shown excellent sensitivities in this respect, few reports have demonstrated the applicability of these methods to relatively large sample cohorts. In this work, a fast protocol based on TiO2 enrichment and highly sensitive mass spectrometric analysis by Selected Reaction Monitoring (SRM) has been applied to a cohort of serum samples from prostate cancer and benign prostatic hyperplasia patients in order to detect low abundance proteins in a single LC-MS/MS analysis in nanoscale format, without immunodepletion or peptide fractionation. A peptide library of over 700 formerly N-glycosylated peptides was created by data dependent analysis. Then, 16 medium to low abundance proteins were selected for detection by single injection LC-MS/MS based on selected-reaction monitoring. Results demonstrated the consistent detection of the low-level proteins under investigation. Following label-free quantification, four proteins (Adipocyte plasma membrane-associated protein, Periostin, Cathepsin D and Lysosome-associated membrane glycoprotein 2) were found significantly increased in prostate cancer sera compared to the control group.

RESUMO

OBJECTIVE: To build a nomogram able to predict treatment success after collagenase Clostridium histolyticum (CCH) for Peyronie's disease (PD). MATERIALS AND METHODS: Between November 2016 and November 2017, we enrolled 135 patients with PD into a multicentre single-arm prospective study. All patients enrolled received CCH treatment. Success of therapy was defined as a decrease in penile curvature (PC) of ≥20° from baseline. Treatment satisfaction was assessed using a scale from 1 to 10, and high satisfaction was arbitrarily defined as a score of ≥8. Calcification level was classified as: absence of calcification; low perilesional calcification; and high calcification. RESULTS: The median (interquartile range [IQR]) patient age was 56.0 (45.0-65.0) years and the median (IQR) was PC was 30 (30.0-60.0)°. After the treatment protocol, we observed a significant median change in PC of -20.0° (P < 0.01). The median (IQR) PC improvement was 44 (28.0-67.0)%. Overall median (IQR) satisfaction score was 8.0 (7.0-9.0). Treatment efficacy was reported in a total of 77 patients (57.04%). When analysing factors associated with PC improvement after treatment, we found that baseline PC (odds ratio [OR] 1.14; P < 0.01), basal plaque (OR 64.27; P < 0.01), low calcification (OR 0.06; P < 0.01) and high calcification (OR 0.03; P < 0.01) were significant predictors of PC improvement. The c-index for the model was 0.93. CONCLUSIONS: Patients with longer PD duration, greater baseline PC and basal plaque location had a greater chance of treatment success. These results could be applied to clinical practice before external validation of our nomogram.

RESUMO

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.

RESUMO

BACKGROUND: Collagenase Clostridium histolyticum (CCH; Xiapex) injections represent the only licensed medical treatment for Peyronie's disease (PD). AIM: To evaluate the efficacy and safety of CCH injections in men with stable PD, using a modified treatment protocol and to assess partners' bother improvement in a large cohort of White-European sexually active heterosexual men treated in a single tertiary-referral center. METHODS: All the 135 patients enrolled underwent a thorough assessment, which included history taking, physical examination, and pharmacologically induced artificial erection test (intra-cavernous injection) to assess the degree of penile curvature (PC) at baseline and after the completion of the treatment. Patients with calcified plaque and/or ventral curvature were excluded. All patients underwent a modified treatment protocol, which consisted of 3 intra-lesional injections of 0.9 mg of CCH performed at 4-week intervals at the point of maximum curvature. After each injection, patients were instructed to follow a strict routine involving daily penile stretching in the intervals between injections. OUTCOMES: International Index of Erectile Function (IIEF)-15, Global Assessment of PD, PD questionnaires (PDQ), and Female Sexual Function Index (FSFI) questionnaire were performed at baseline and at the end of treatment. RESULTS: Overall, 135 patients completed the study protocol. Before treatment, 18 (13.33%) partners showed a degree of sexual dysfunction. Baseline median IIEF-15, FSFI, and PDQ scores were, respectively, 59.0, 35.0, and 23.0. Overall, both IIEF-total and all domains significantly improved after treatment (all P < .01). A PC mean change of 19.07 (P = .00) was measured. At the univariate linear regression analysis, IIEF-15, IIEF-erectile function, IIEF-sexual desire, and IIEF-intercourse satisfaction were positively associated with FSFI (all P ≤ .03); conversely, PDQ-penile pain, PDQ-symptom bother, and post-treament penile curvature (P ≤ .04) were associated with a decreased FSFI score. Furthermore, median change of PC was significantly associated with median change of FSFI (r = 0.25; 95% CI 0.02-0.11; P = .004). Global satisfaction after treatment was 89.6% (121/135). CLINICAL TRANSLATION: This modified CCH treatment protocol could improve both patients' and partner's sexual function. STRENGTH AND LIMITATIONS: This was an open-label, single-arm clinical study, without placebo. where only heterosexual couples in stable relationships were included. Furthermore, no real assessment of female sexual distress was carried out and long-term sexual function in both patients and female partners were not taken into account. CONCLUSIONS: The modified treatment schedule with CCH injections for stable PD has a positive impact on both patients' and partners' sexual function in heterosexual couples with a stable sexual relationship.

RESUMO

INTRODUCTION: The aim of this multicenter study was to investigate the prognostic impact of residual T1 high-grade (HG)/G3 tumors at re-transurethral resection (TUR of bladder tumor) in a large multi-institutional cohort of patients with primary T1 HG/G3 bladder cancer (BC). PATIENTS AND METHODS: The study period was from January 2002 to -December 2012. A total of 1,046 patients with primary T1 HG/G3 and who had non-muscle invasive BC (NMIBC) on re-TUR followed by adjuvant intravesical Bacillus Calmette-Guerin (BCG) therapy with maintenance were included. Endpoints were time to disease recurrence, progression, and overall and cancer-specific death. RESULTS: A total of 257 (24.6%) patients had residual T1 HG/G3 tumors. The presence of concomitant carcinoma in situ, multiple and large tumors (> 3 cm) at first TUR were associated with residual T1 HG/G3. Five-year recurrence-free survival (RFS), progression-free survival (PFS), overall survival (OS), and cancer-specific survival (CSS) were 17% (CI 11.8-23); 58.2% (CI 50.7-65); 73.7% (CI 66.3-79.7); and 84.5% (CI 77.8-89.3), respectively, in patients with residual T1 HG/G3, compared to 36.7% (CI 32.8-40.6); 71.4% (CI 67.3-75.2); 89.8% (CI 86.6-92.3); and 95.7% (CI 93.4-97.3), respectively, in patients with NMIBC other than T1 HG/G3 or T0 tumors. Residual T1 HG/G3 was independently associated with RFS, PFS, OS, and CSS in multivariable analyses. CONCLUSIONS: Residual T1 HG/G3 tumor at re-TUR confers worse prognosis in patients with primary T1 HG/G3 treated with maintenance BCG. Patients with residual T1 HG/G3 for primary T1 HG/G3 are very likely to fail BCG therapy alone.

RESUMO

BACKGROUND: A new oro-dispersible film (ODF) formulation of sildenafil has been developed for the treatment of erectile dysfunction (ED) to overcome the drawbacks that some patients experience when taking the conventional film-coated tablet (FCT). AIM: To assess the effectiveness and safety of sildenafil ODF formulation in patients with ED who were using the conventional FCT. METHODS: From May 2017 through July 2017, 139 patients with ED were enrolled. Data from penile color-duplex ultrasound, medical history, hormonal evaluation, and patient self-administered questionnaires were collected. All patients were administered sildenafil 100-mg FCT for 4 weeks. Thereafter, they underwent a 2-week washout period and subsequently took sildenafil 75-mg ODF for 4 weeks. OUTCOMES: The International Index of Erectile Function (IIEF-15), Hospital Anxiety and Depression Scale (HADS), Patient Global Impressions of Improvement (PGI-I), and Clinician Global Impressions of Improvement (CGI-I) questionnaires were administered and severity of ED was classified as severe (IIEF-15 score ≤ 10), moderate (IIEF-15 score 11-16), or mild (IIEF-15 score = 17-25). RESULTS: All patients completed the final protocol. Differences in mean IIEF scores for erectile function, orgasmic function, sexual desire, and intercourse satisfaction were significantly in favor of sildenafil 100-mg FCT, whereas the mean score for overall satisfaction was in favor of sildenafil 75-mg ODF. A significant difference in changes in HADS score was found from washout to final follow-up (mean difference = -0.19; P < .01). For the ODF formulation, the median CGI-I score was 3.5 (interquartile range [IQR] = 2.5-4.5) and the median PGI-I score was 3.0 (IQR = 2.0-4.0). The median action time was 20.0 minutes (IQR = 15.0-30.0) and the median mouth time was 60.0 seconds (IQR = 30.0-120.0). CLINICAL IMPLICATIONS: The ODF formulation of a widely known drug, with the same safety and effectiveness of the FCT, was better appreciated by patients in overall satisfaction. STRENGTHS AND LIMITATIONS: This is the first clinical trial to assess the efficacy of a new formulation of sildenafil in patients with ED. The limitations of the study are related to the methodology used: it was not a case-control study and the patients were not drug-naïve for ED treatment. Therefore, only the "additional" side effects of the ODF formulation compared with FCT are reported. CONCLUSION: The new ODF formulation is as efficient and safe as the FCT formulation and offers a new choice of treatment to specialists for more precisely tailored therapy.
