RESUMEN

BACKGROUND: There is a strong clinical need to fill the gap of identifying clinically significant prostate cancer (csPCa) in men with prostate-specific antigen (PSA) gray zone values. Promising, but not definitive results have been obtained using PSA derivatives such as prostate health index (PHI) and PHI density (PHID) and the percentage (-2)proPSA/free PSA (%p2PSA/fPSA). Thus, this study aimed to compare the diagnostic value of PHI, PHID, %proPSA/fPSA, and (-2)proPSA/freePSA density (-2pPSA/fPSAD) for csPCa in the patients with PSA within 2-10 ng/mL. METHODS: Serum samples and clinicopathological features were prospectively collected from 142 patients who underwent robot-assisted radical prostatectomy  between September 2021 and December 2023. According to the inclusion criteria, the patients with total PSA  within 2 and 10 ng/mL and negative or suspicious digital rectal examination  were enrolled. We used two different classifications for csPCa: 1) patients with Gleason score (GS) ≥ 7(4 + 3) and 2) patients with GS ≥ 7(3 + 4). The receiver operating characteristic curves and the area under the curve (AUC) values were used to assess the diagnostic performance. RESULTS: Of the 142 men included, 116 (82%) patients were diagnosed with csPCa as GS ≥ 3 + 4 and 107 (75%) defined as csPCa as GS ≥ 7(4 + 3), respectively. We found that p2PSA/fPSA, p2PSA/fPSAD, PHI, and PHID were significantly higher in csPCa classified as GS ≥ 7(3 + 4) as well as GS ≥ 7(4 + 3), with p-values 0.027, 0.054, 0.0016, and 0.0027, respectively. AUCs of the analyzed variables were higher when used to predict csPCa as GS ≥ 6 compared to csPCa as GS ≥7(4 + 3), with an AUC equal, respectively, to 0.679 (95% CI: 0.571-0.786), 0.685 (95% CI: 0.571-0.799), 0.737 (95% CI: 0.639-0.836), and 0.736 (95% CI: 0.630-0.841) in the first subgroup and with an AUC equal, respectively, to 0.653 (95% CI: 0.552-0.754), 0.665 (95% CI: 0.560-0.770), 0.668 (95% CI: 0.568-0.769), and 0.670 (95% CI: 0.567-0.773) in the second, respectively. Both PHID and p2PSA/fPSAD allowed improvement in the diagnostic accuracy with respect to PHI and p2PSA/fPSA ratio, however the differences were not statistically significant (p = 0.409, 0.180 for csPCa as G ≥ Gleason grade (GG) 2 and 0.558 and 0.087 for csPCa as G ≥ GG3, respectively). We found that PHI, PHID, p2PSA/fPSA ratio, and p2PSA/fPSAD showed higher sensitivity, specificity, and positive predictive value when used to predict csPCa as GG ≥ 2, whereas negative predictive value of all four parameters was higher when used to predict GG ≥ 3. CONCLUSIONS: In men with a PSA level between 2 and 10 ng/mL, PHI and PHID, p2PSA/fPSA, and p2PSA/fPSAD showed good diagnostic performance for postoperative csPCa. However, PHID and p2PSA/fPSAD had a small advantage over PHI which needs to be further investigated for the reduction of unnecessary surgical interventions. This finding suggests that it could be a promising biomarker for making the treatment-decision strategy.

RESUMEN

OBJECTIVE: Evaluate the detection rates of systematic, targeted and combined cores at biopsy according to tumor positions in biopsy-naïve patients. MATERIAL AND METHODS: A retrospective analysis of a single-center patient cohort (n = 501) that underwent transrectal prostate biopsy between January 2017 and December 2019 was performed. Multi-parametric MRI was executed as a prebiopsy investigation. Biopsy protocol included, for each patient, 12 systematic cores plus 3 to 5 targeted cores per lesion identified at the mpMRI. Pearson and McNemar chi-squared tests were used for statistical analysis to compare tumor location-related detection rates of systematic, targeted and combined (systematic + targeted) cores at biopsy. RESULTS: Median age of patients was 70 years (IQR 62-72), with a median PSA of 8.5 ng/ml (IQR 5.7-15.6). Positive biopsies were obtained in 67.7% of cases. Overall, targeted cores obtained higher detection rates compared to systematic cores (54.3% vs. 43.1%, p < 0.0001). Differences in detection rates were, however, higher for tumors located at the apex (61.1% vs. 26.3%, p < 0.05) and anteriorly (44.4% vs. 19.3%, p < 0.05). Targeted cores similarly obtained higher detection rates in the posterior zone of the prostate gland for clinically significant prostate cancer. A poor agreement was reported between targeted and systematic cores for the apex and anterior zone of the prostate with, respectively κ = 0.028 and κ = -0.018. CONCLUSION: A combined approach of targeted and systematic biopsy delivers the highest detection rate in prostate cancer (PCa). The location of the tumor could however greatly influence overall detection rates, indicating the possibility to omit (as for the base or posterior zone of the gland) or add (as for the apex or anterior zone of the gland) further targeted cores.

RESUMEN

Renal cell carcinoma (RCC) remains a formidable diagnostic challenge, especially in the context of small renal masses. The quest for non-invasive screening tools and biomarkers has steered research towards liquid biopsy, focusing on microRNAs (miRNAs), exosomes, and circulating tumor cells (CTCs). MiRNAs, small non-coding RNAs, exhibit notable dysregulation in RCC, offering promising avenues for diagnosis and prognosis. Studies underscore their potential across various biofluids, including plasma, serum, and urine, for RCC detection and subtype characterization. Encouraging miRNA signatures show correlations with overall survival, indicative of their future relevance in RCC management. Exosomes, with their diverse molecular cargo, including miRNAs, emerge as enticing biomarkers, while CTCs, emanating from primary tumors into the bloodstream, provide valuable insights into cancer progression. Despite these advancements, clinical translation necessitates further validation and standardization, encompassing larger-scale studies and robust evidence generation. Currently lacking approved diagnostic assays for renal cancer, the potential future applications of liquid biopsy in follow-up care, treatment selection, and outcome prediction in RCC patients are profound. This review aims to discuss and highlight recent advancements in liquid biopsy for RCC, exploring their strengths and weaknesses in the comprehensive management of this disease.

RESUMEN

AIM: Renal leiomyoma is a rare benign mesenchymal tumor arising from the smooth muscle cells of the kidney. Renal capsule is its most common location (1). Large tumor may require surgical excision which can be challenging in case of proximity to major vessels (2). Indications of robotic partial nephrectomy (RPN) have exponentially expanded over the past few years (3). We aim to report a case of large renal leiomyoma successfully managed with RPN. METHODS: A 59-year-old female patient with BMI 51 presented with chief complaint of abdominal discomfort. The patient underwent a CT scan that revealed a massive circumscribed exophytic complex solid cystic mass of 4.5 x 7.7 x 6.2 cm, arising from the lower pole of right kidney and abutting the inferior vena cava. RENAL score was 11ah (high complexity). Past surgical history included mid-urethral sling, breast reduction, and hysterectomy with salpingectomy. Preoperative creatinine and eGFR were 0.9 (mg/dL) and 77 (mL/min), respectively. A robotic excision of this mass was successfully performed by using Da Vinci Xi platform. Main steps of the procedure are illustrated in the present video. RESULTS: Dissection and isolation of the tumor were carefully performed after identifying key anatomical structures such as the ureter, the IVC and the renal hilum. Intraoperative ultrasound was used to confirm the margins of the mass. The renal artery was clamped and then the tumor was resected/enucleated. Renal parenchyma was re-approximated with a single layer of interrupted CT-1 Vicryl 0 with sliding clip technique. Warm ischemia time was 19 min. Estimated blood loss (EBL) was 250 ml. Operative time was 165 min. No intraoperative complications occurred. No drain was placed. Patient was discharged on postoperative day 2. Post-operative hypotension was managed with fluid bolus. Postoperative creatinine and eGFR were 1,0 (mg/dL) and 69 (mL/min/1.72m2), respectively. Pathology revealed a leiomyoma of genital stromal origin with hyalinization and calcification. CONCLUSIONS: To the best of our knowledge, this is the first description of RPN for the management of a large (about 8 cm) renal leiomyoma. Robotic assisted surgery allows to expand the indications of minimally invasive conservative renal surgery whose feasibility becomes even more clinically significant in case of benign masses which can be managed without sacrificing healthy renal parenchyma.

RESUMEN

Background and Objectives: To describe the predictors of cribriform variant status and perineural invasion (PNI) in robot-assisted radical prostatectomy (RARP) histology. To define the rates of upgrading between biopsy specimens and final histology and their possible predictive factors in prostate cancer (PCa) patients undergoing RARP. Material and Methods: Within our institutional database, 265 PCa patients who underwent prostate biopsies and consecutive RARP at our center were enrolled (2018-2022). In the overall population, two independent multivariable logistic regression models (LRMs) predicting the presence of PNI or cribriform variant status at RARP were performed. In low- and intermediate-risk PCa patients according to D'Amico risk classification, three independent multivariable LRMs were fitted to predict upgrading. Results: Of all, 30.9% were low-risk, 18.9% were intermediate-risk and 50.2% were high-risk PCa patients. In the overall population, the rates of the cribriform variant and PNI at RARP were 55.8% and 71.1%, respectively. After multivariable LRMs predicting PNI, total tumor length in biopsy cores (>24 mm [OR: 2.37, p-value = 0.03], relative to <24 mm) was an independent predictor. After multivariable LRMs predicting cribriform variant status, PIRADS (3 [OR:15.37], 4 [OR: 13.57] or 5 [OR: 16.51] relative to PIRADS 2, all p = 0.01) and total tumor length in biopsy cores (>24 mm [OR: 2.47, p = 0.01], relative to <24 mm) were independent predicting factors. In low- and intermediate-risk PCa patients, the rate of upgrading was 74.4% and 78.0%, respectively. After multivariable LRMs predicting upgrading, PIRADS (PIRADS 3 [OR: 7.01], 4 [OR: 16.98] or 5 [OR: 20.96] relative to PIRADS 2, all p = 0.01) was an independent predicting factor. Conclusions: RARP represents a tailored and risk-adapted treatment strategy for PCa patients. The indication of RP progressively migrates to high-risk PCa after a pre-operative assessment. Specifically, the PIRADS score at mpMRI should guide the decision-making process of urologists for PCa patients.

RESUMEN

OBJECTIVE: To evaluate the quality information on testicular cancer uploaded on YouTube™ videos. METHODS: YouTube™ videos were searched using "Testicular cancer" as a keyword. The Patient Education Materials Assessment Tool, the Misinformation scale, and the DISCERN tool were used to assess the quality information of YouTube™ videos on testicular cancer. RESULTS: According to the selection criteria, 121 YouTube™ videos were collected for the analysis and stratified according to uploading year (2009-2014 vs 2015-2020). According to the Patient Education Materials Assessment Tool for audio-visual content, the overall Understandability score was 60% (interquartile range 45.5-75) and the overall Actionability score was 100% (interquartile range 66.7-100). According to the Misinformation scale, the lowest median was recorded for item 6 ("Effects on fertility") and the overall median Misinformation score was 2 (interquartile range 1.3-2.8). No statistically significant differences were observed according to uploading year (all P > 0.05). Of all, only 54 (44.6%) videos mentioning treatment were subsequently analyzed. Of these videos, the overall Understandability was 71.4% (interquartile range 56.3-84.6) and the overall Actionability was 100% (interquartile range 66.7-100). The overall Misinformation score was 2.8 (interquartile range 2.2-3.5). The median DISCERN score recorded for question 16 was 5 (interquartile range 3-5). CONCLUSIONS: YouTube™ is a fast and open-access source for mass information. The overall quality of the testicular cancer contents provided is sadly unsatisfactory, in the present likewise in the past. However, YouTube™ videos mentioning treatment options showed higher quality content, than the remaining one. Nevertheless, all the videos analyzed underestimated the testicular cancer effects on fertility. Nowadays, YouTube™ cannot be recommended as a reliable source of information on testicular cancer.

RESUMEN

Muscle invasive bladder cancer (MIBC) is a widespread malignancy with a worse prognosis often related to a late diagnosis. For early-stage MIBC pts, a multidisciplinary approach is mandatory to evaluate the timing of neoadjuvant chemotherapy (NAC) and surgery. The current standard therapy is platinum-based NAC (MVAC-methotrexate, vinblastine, doxorubicin, and cisplatin or Platinum-Gemcitabine regimens) followed by radical cystectomy (RC) with lymphadenectomy. However, preliminary data from Vesper trial highlighted that dose-dense NAC MVAC is endowed with a good pathological response but shows low tolerability. In the last few years, translational-based research approaches have identified several candidate biomarkers of NAC esponsiveness, such as ERCC2, ERBB2, or DNA damage response (DDR) gene alterations. Moreover, the recent consensus MIBC molecular classification identified six molecular subtypes, characterized by different sensitivity to chemo- or targeted or immunotherapy, that could open a novel procedure for patient selection and also for neoadjuvant therapies. The Italian PURE-01 phase II Trial extended data on efficacy and resistance to Immune Checkpoint Inhibitors (ICIs) in this setting. In this review, we summarize the most relevant literature data supporting NAC use in MIBC, focusing on novel therapeutic strategies such as immunotherapy, considering the better patient stratification and selection emerging from novel molecular classification.

RESUMEN

Background and Objective: Blood loss represents a long-standing concern of radical prostatectomy (RP). This study aimed to assess how red line cell values changed following robot-assisted radical prostatectomy (RARP) for prostate cancer (PCa). Materials and Methods: The blood panels of 453 consecutive PCa patients undergoing RARP at a single tertiary academic referral center, from September 2020 to April 2022, were reviewed. Data from 363 patients with the blood panel available for the following timeframe: within seven days before surgery, six hours after surgery, and the first three postoperative days, were analyzed. Specifically, hemoglobin (Hb, g/dL), red blood cells (RBCs, ×106/µL), and hematocrit (HCT, %) trends were collected. Results: Considering the Hb trend, the median values in the preoperative day, postoperative day (POD) 2, and POD 3 are 14.7 (interquartile range (IQR) = 13.9−15.4), 12.1 (IQR = 11.2−12.9), and 12.2 (IQR = 11.2−13.1), respectively. The ∆ between preoperative day and POD 2 is 2.5 (IQR = 1.8−3.2) (p < 0.001). Considering the RBCs trend, the median values in the preoperative day, POD 2, and POD 3 are 4.9 (IQR = 4.7−5.3), 4.1 (IQR = 3.8−4.4), and 4.1 (IQR = 3.8−4.5), respectively. The ∆ between preoperative day and POD 2 is 0.9 (IQR = 0.6−1.1) (p < 0.001). Considering the HCT trend, the median values in the preoperative day, POD 2, and POD 3 are 44.4 (IQR = 41.7−46.6), 36.4 (IQR = 33.8−38.9), and 36.1 (IQR = 33.5−38.7), respectively. The ∆ between preoperative day and POD 2 is 7.8 (IQR = 5.2−10.5) (p < 0.001). Conclusions: Overall, patients undergoing RARP experience a significant, but clinically limited, decline in red line cell values between the preoperative time and the second day post-surgery. These observations are important to provide physicians with knowledge of the expected postoperative course and, thus, to improve the quality of patient care.

RESUMEN

Growing evidence supports the pivotal role played by periprostatic adipose tissue (PPAT) in prostate cancer (PCa) microenvironment. We investigated whether PPAT can affect response to Docetaxel (DCTX) and the mechanisms associated. Conditioned medium was collected from the in vitro differentiated adipocytes isolated from PPAT which was isolated from PCa patients, during radical prostatectomy. Drug efficacy was studied by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide citotoxicity assay. Culture with CM of human PPAT (AdipoCM) promotes DCTX resistance in two different human prostate cancer cell lines (DU145 and PC3) and upregulated the expression of BCL-xL, BCL-2, and TUBB2B. AG1024, a well-known IGF-1 receptor inhibitor, counteracts the decreased response to DCTX observed in presence of AdipoCM and decreased TUBB2B expression, suggesting that a paracrine secretion of IGF-1 by PPAT affect DCTX response of PCa cell. Collectively, our study showed that factors secreted by PPAT elicits DCTX resistance through antiapoptotic proteins and TUBB2B upregulation in androgen independent PCa cell lines. These findings reveal the potential of novel therapeutic strategies targeting adipocyte-released factors and IGF-1 axis to overcome DCTX resistance in patients with PCa.

RESUMEN

BACKGROUND: Few studies have investigated how physical, mental and sexual function are associated with each other in operated transgender women (oTW). AIM: To provide information on the physical, mental and sexual health of oTW in comparison with a group of cisgender women (cisW). METHODS: An age-matched control study was carried out, recruiting 125 oTW in 7 national referral centers and 80 volunteer women. Beck Depression Inventory Primary Care (BDI-PC), General Health Survey (SF-36), Female Sexual Function Index (FSFI) and operated Male to Female Sexual Function Index (oMtFSI) questionnaires were web-based administered. Data included: age, area of origin, educational level, sexual orientation, years since surgery and hormone therapy. OUTCOMES: T-test was applied to inspect mean score differences between oTW and cisW, in mental, sexual and physical health; simple correlations and multiple regression analysis revealed how mental, sexual and physical health were concurrently associated in the two groups RESULTS: Response rate 60% (52% oTW, 71% cisW). oTW mean age 38.5 years (SD = 9.3), cisW 37.7 years (SD = 11.5). Both cisW and oTW reported average values in the range of mental, physical and sexual health. Statistical comparisons revealed no significant group differences in mental and physical health. oTW who referred a worse sexual function also reported worse overall mental well-being and higher levels of depressive symptoms. FSFI scores were negatively associated with years since surgery, but not with age. Multiple regression analysis showed that FSFI Pain accounted for a significant unique variance proportion of risk of depression in oTW. FSFI Sexual Pain was the strongest estimator of inter-individual differences in BDI-PC among oTW (P < .01). CLINICAL IMPLICATIONS: No significant differences in the levels of depressive symptoms, physical and mental well- being were found in oTW and cis-W. The relation between depressive symptoms and sexual function in oTW is stronger than in cisW, and sexual pain substantially predicts risk of depression in oTW. STRENGTHS & LIMITATIONS: The evaluation of outcomes using validated questionnaires and the relatively large sample size. The convenience control group reported mental, physical and sexual health levels within the range of Italian normative data. Since this is a cross-sectional study, we must be careful in drawing conclusions from our results. CONCLUSIONS: Sexual pain and lubrication difficulties are the main causes of worse sexual function in oTW, highlighting the importance of perioperative counseling to make surgical expectations realistic and to educate to a proper neovagina management.

RESUMEN

INTRODUCTION: Data regarding the risk of incontinence after cesarean hysterectomy are lacking. We aimed to assess the risk of urinary incontinence in women who underwent planned cesarean hysterectomy for placenta accreta. METHODS: This was a retrospective study of women who underwent planned cesarean hysterectomy for placenta accreta. The primary outcome was the incidence of post-cesarean hysterectomy urinary incontinence, defined as involuntary loss of urine between 3 and 12 months after cesarean hysterectomy. Outcomes were compared in a cohort of women who underwent planned cesarean hysterectomy for placenta accreta with a control group of women who underwent scheduled cesarean section without hysterectomy. RESULTS: Forty-seven singleton gestations who underwent planned cesarean hysterectomy for placenta accrete were included in the study and were compared with 100 controls. Eight cases of bladder injuries were reported, 7 in the planned cesarean hysterectomy group and one in the planned cesarean delivery group. Overall, urinary incontinence was reported in 10 women of the planned cesarean hysterectomy group and in 8 women of the planned cesarean section group (21.3% vs. 8.0%; p = 0.03). CONCLUSION: Planned cesarean hysterectomy for placenta accreta is a risk factor for urinary incontinence.

RESUMEN

OBJECTIVES: To examine the effect of specific Asian ethnic subgroups on stage at presentation and cancer-specific mortality in non-metastatic upper tract urothelial carcinoma among North American upper tract urothelial carcinoma Asian patients treated with radical nephroureterectomy. METHODS: We relied on the Surveillance, Epidemiology and End Results database, from 2004 to 2016. Kaplan-Meier plots and multivariable Cox regression models predicting cancer-specific mortality were used. RESULTS: Of 584 upper tract urothelial carcinoma patients, 173 (29.6%) were Chinese versus 130 (22.3%) Japanese versus 68 (11.6%) Korean versus 64 (11.0%) Filipino versus 40 (6.8%) Vietnamese versus 109 (18.7%) other. Vietnamese and Chinese patients showed the highest rates of T4 N0 M0 and/or T1-4 N1-2 M0 (25.0% and 18.5%, respectively), relative to other Asian ethnic subgroups. In Kaplan-Meier plots, Vietnamese patients showed the highest cancer-specific mortality rate. In multivariable models, Vietnamese ethnicity also independently predicted higher cancer-specific mortality (hazard ratio 2.15, P = 0.02 and hazard ratio 1.96, P = 0.03), relative to Japanese and Chinese patients. All other Asian ethnic subgroups showed similar cancer-specific mortality patterns. CONCLUSION: Vietnamese and Chinese patients are at a stage disadvantage at upper tract urothelial carcinoma diagnosis, relative to all other Asian ethnicities. After adjustment for stage, only Vietnamese patients showed a survival disadvantage relative to all other Asian ethnic subgroups. As a result, it appears that Vietnamese patients not only present at a higher upper tract urothelial carcinoma stage, but additionally appear to harbor upper tract urothelial carcinoma that progresses at a faster rate than in other Asian ethnic subgroups.

RESUMEN

BACKGROUND: To date, the clinical characteristics of coronavirus disease 19 (COVID-19)-infected urologic cancer patients are unknown. METHODS: We have analyzed all patients with prostate cancer undergoing hormonal or chemotherapy treatment and receiving telephone and in person pre-triage between March 1 and 27, 2020, at the Tortora Hospital, Pagani, Italy. RESULTS: Among 72 patients, 48 and 24 were hormone-sensitive (HS) and castration-resistant prostate cancer (CRPC), respectively; 0 HS and 2 (8.3%) CRPC (p < 0.05) were positive for COVID-19. Both patients were receiving LHRH agonist therapy, and 1 patient was receiving enzalutamide. Urgent intensive care unit admission was required due to clinical worsening. Blood tests showed severe lymphopenia, anemia, and an increase in platelets. Retroviral therapy, antibiotics, heparin, and chloroquine were prescribed at the beginning. One patient also received tocilizumab as a salvage treatment. After 3 weeks of hospitalization, the patients were discharged from the hospital. Both patients suffered from an aggressive COVID-19 course due to concomitant comorbidities. CONCLUSIONS: Investigating whether hormonal therapy, especially in advanced disease, acts as a protective factor or a risk factor during COVID-19 could be useful.

RESUMEN

BACKGROUND: The overlap between some painful conditions is widespread. The aim of this study was to evaluate the overlap between burning mouth syndrome (BMS) and urological chronic pelvic pain syndrome (UCPPS) in an outpatient clinic of a university hospital. METHODS: A controlled clinical study was performed. BMS patients and healthy controls were enrolled in the study. Patients were screened through laboratory test and a complete urological examination. Two validated questionnaires were submitted to all the patients: National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and International Prostatic Symptom Score (IPSS). RESULTS: A total of 50 BMS patients and 50 healthy controls were enrolled in the study. Statistically significant differences between the two groups regarding the items of the IPSS questionnaire of Incomplete Emptying (U = 750, P < .001), Intermittency (U = 768.5, P < .001), QoL (U = 848, P < .002), and Total Symptom score (U = 1040, P = .05) were found. Moreover, the responses of NIH-CPSI showed statistically significant differences regarding Pain subscale (U = 714, P < .001), QoL Impact subscale (U = 1016.500, P = .05), and NIH-CPSI total score (U = 953.500, P = .002). CONCLUSION: To the best our knowledge, the reported data demonstrate for the first time an association between BMS and UCPPS. Further studies with a larger sample are needed to confirm the co-occurrence of urological symptoms in patients with burning mouth syndrome.

RESUMEN

OBJECTIVE: To evaluate health-related quality of life (HR-QoL) outcomes in elderly patients with different type of urinary diversion (UD), ileal conduit (IC) and ileal orthotopic neobladder (IONB), after radical cystectomy (RC) for bladder cancer, by using validated self-reported cancer-specific instruments. PATIENTS AND METHODS: We retrospectively reviewed 77 patients who received an IC or an IONB after RC. HR-QoL was assessed with specific and validated disease questionnaires, administered at last follow-up. RESULT: At univariate analysis, at a mean follow-up of 60.91 ± 5.63 months, IONB results were favourable with regard to the following HR-QoL aspects: nausea and vomiting (p = 0.045), pain (p = 0.049), appetite loss (p = 0.03), constipation (p = 0.000), financial impact (p = 0.012) and cognitive functioning (p = 0.000). This last functional aspect was significantly worse in female patients (p = 0.029). Emotional functioning was significantly better in patients without long-term complications (p = 0.016). At multivariate analysis, male gender and IONB were independent predictors of better cognitive functioning, while long-term complications negatively affected emotional functioning. CONCLUSIONS: Obtained results suggest that an IONB can also be suitable for elderly patients compared with an IC with few and selected advantages in favour of the former UD. Preoperative patient's selection, counselling, education and active participation in the decision-making process lead to a more suitable choice of treatment.

RESUMEN

OBJECTIVES: To assess the predictive accuracy and the clinical value of a recent nomogram predicting cancer-specific mortality-free survival after surgery in pN1 prostate cancer patients through an external validation. METHODS: We evaluated 518 prostate cancer patients treated with radical prostatectomy and pelvic lymph node dissection with evidence of nodal metastases at final pathology, at 10 tertiary centers. External validation was carried out using regression coefficients of the previously published nomogram. The performance characteristics of the model were assessed by quantifying predictive accuracy, according to the area under the curve in the receiver operating characteristic curve and model calibration. Furthermore, we systematically analyzed the specificity, sensitivity, positive predictive value and negative predictive value for each nomogram-derived probability cut-off. Finally, we implemented decision curve analysis, in order to quantify the nomogram's clinical value in routine practice. RESULTS: External validation showed inferior predictive accuracy as referred to in the internal validation (65.8% vs 83.3%, respectively). The discrimination (area under the curve) of the multivariable model was 66.7% (95% CI 60.1-73.0%) by testing with receiver operating characteristic curve analysis. The calibration plot showed an overestimation throughout the range of predicted cancer-specific mortality-free survival rates probabilities. However, in decision curve analysis, the nomogram's use showed a net benefit when compared with the scenarios of treating all patients or none. CONCLUSIONS: In an external setting, the nomogram showed inferior predictive accuracy and suboptimal calibration characteristics as compared to that reported in the original population. However, decision curve analysis showed a clinical net benefit, suggesting a clinical implication to correctly manage pN1 prostate cancer patients after surgery.

RESUMEN

OBJECTIVE: We investigated the efficacy of intravesical instillations of combined hyaluronic acid (HA) and chondroitin sulphate (CS) in patients with bacillus Calmette-Guérin (BCG)-induced chemical cystitis unresponsive to first-line therapies. PATIENTS AND METHODS: We retrospectively reviewed the clinical records of patients with grade 2 BCG-induced chemical cystitis unresponsive to first line therapeutic options performed according to the International Bladder Cancer Group guidelines who underwent intravesical instillations of HA/CS. Bladder pain, urinary urgency, voiding volume and number of voids/24 hours recorded prior to treatment, at the end of the treatment, at six months and at one-year follow-up were recorded and analyzed. RESULTS: The records of 20 patients were identified. All patients underwent eight weekly instillations of HA/CS. Mean baseline visual analogue scale (VAS) scores ± Standard Deviation (SD) for urinary urgency and bladder pain were 7.8 ± 0.5 and 7.2 ± 1.0, respectively. Mean number of voids/24 hours ± SD was 15.4 ± 2.3 and mean urine volume per void ± SD was 85.8 ± 21.0 mL. At the end of the treatment, mean VAS scores ± SD for urgency and pain significantly decreased to 4.7 ± 1.1 and 4.2 ± 0.9, respectively (p < 0.05 in both cases). Mean number of voids/24 hours ± SD decreased to 9.6 ± 1.4 (p < 0.05) and mean urine volume per void ± SD significantly increased to 194.1 ± 59.5 mL (p < 0.05). At six months and one-year followup, all outcome measures remained stable. CONCLUSIONS: Bladder instillations of HA/CS provide significant and durable improvement of bladder pain, urinary urgency, urinary volume per void and urinary frequency in patients with refractory BCG-induced chemical cystitis.

RESUMEN

Erectile function is a widely accepted indicator of systemic endothelial activity since from a clinical standpoint erectile dysfunction (ED) often precedes cardiovascular events. Recently it has been described a potential role for ß3 adrenoceptor in cardiovascular diseases emphasizing a possible development of new drugs. ß3 adrenoceptor stimulation relaxes human corpus cavernosum (HCC) strips in cyclic guanosine monophosphate (cGMP)-dependent and endothelium/nitric oxide (NO)-independent manner. Hydrogen sulfide (H2S), along with NO, is another gaseous molecule involved in cardiovascular system and as a consequence also in penile erection. Cystathionine-ß-synthase (CBS) and cystathionine-γ-lyase (CSE), the enzymes mainly responsible for H2S biosynthesis, are constitutively expressed in HCC. CSE rather than CBS is more abundant in human penile tissue. Herein we investigated the involvement of H2S pathway in ß3 adrenoceptor-induced relaxation in HCC and penile artery. Penile artery expresses both CSE and ß3 adrenoceptor. BRL37344, a ß3 selective agonist, relaxed HCC strips and penile artery rings and this effect was significantly reduced by CSE inhibition. Incubation of HCC and penile artery homogenate with BRL37344 significantly increased H2S production. This effect was significantly reduced by the inhibition of either CSE or ß3 adrenoceptor. Finally, the BRL37344-induced increase in cGMP was reduced by CSE inhibition in both tissues. Thus, BRL37344-induced relaxation in HCC and penile artery occurs in a H2S/cGMP-dependent manner. In conclusion, ß3/H2S/cGMP pathway can act as an alternative to NO. Since about 15% of patients do not respond to phosphodiesterase-5 inhibitors, ß3 agonists could represent a therapeutic alternative or a useful adjuvant therapy to treat these patients.

RESUMEN

PURPOSE: We aimed to explore the knowledge, attitudes, and practices towards prostate cancer (PCa) risk factors and prevention amongst men living in the southern Italian peninsula. METHODS: We retrospectively reviewed data collected during free preventive visits carried out by the Prevention and Research in Oncology (PRO) non-profit Foundation between July 2013 and July 2016. The following data were collected: demographic and clinical features, knowledge about PCa prevention and sources of knowledge, knowledge about PCa risk factors, previous prostate-specific antigen (PSA) test, previous digital rectal examination (DRE), previous prostate ultrasound, and general attitudes towards DRE. RESULTS: The study population consisted of 2144 Caucasian men living in four regions in the south of Italy (Campania, Calabria, Molise, Puglia). Median age was 59 years. One thousand six hundred and ninety-nine (79.2%) subjects reported knowing the existence of PCa prevention programs. Most of them received information from the media while only 17.1% declared that the information on PCa prevention that they received was from their family physicians. One thousand two hundred seventy-five (59.5%) subjects declared knowing of the existence of PCa risk factors and 41.3% was aware of the existence of both genetic and exogenous factors. The percentage of subjects who reported having had at least one PSA test in their life was 77.8 and 55.4% reported having had a DRE. CONCLUSIONS: Knowledge about PCa screening amongst male subjects living in southern peninsular Italy is quite high. Knowledge of PCa risk factors is suboptimal and the practice of DRE is underutilized.
