RESUMEN

There is an ongoing need for biomarkers that could reliably predict the outcome of BC and that could guide the management of this disease. In this setting, we aimed to explore the prognostic value of the transcription factor P63 in patients with muscle-invasive bladder cancer (MIBC) having undergone radical cystectomy. The correlation between P63 expression and clinicopathological features (tumor stage, nodes involvement, patterns of muscularis propria invasion, papillary architecture, anaplasia, concomitant carcinoma in situ, lymphovascular invasion, perineural invasion, necrosis) and molecular subtyping (basal and luminal type tumors) was tested in 65 radical cystectomy specimens and matched with cancer-specific survival (CSS) and overall survival (OS). P63-negative tumors displayed significantly higher rates of pattern 2 of muscularis propria invasion (50% vs. 14%, p = 0.002) and variant histology (45% vs. 19%, p = 0.022) compared to P63-positive ones. According to the combined expression of CK5/6 and CK20 (Algorithm #1), P63-positive and P63-negative tumors were mostly basal-like and double-negative, respectively (p = 0.004). Using Algorithm #2, based on the combined expression of CK5/6 and GATA3, the vast majority of tumors were luminal overall and in each group (p = 0.003). There was no significant difference in CSS and OS between P63-positive and P63-negative tumors, but the former featured a trend towards longer OS. Though associated with pathological features harboring negative prognostic potential, P63 status as such failed to predict CSS and OS. That said, it may contribute to better molecular subtyping of MIBC.

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

PURPOSE: To evaluate complications and urinary incontinence (UI) after endoscopic enucleation of the prostate (EEP) stratified by prostate volume (PV). METHODS: We retrospectively reviewed patients with benign prostatic hyperplasia who underwent EEP with different energy sources in 14 centers (January 2019-January 2023). INCLUSION CRITERIA: prostate volume ≥ 80 ml. EXCLUSION CRITERIA: prostate cancer, previous prostate/urethral surgery, pelvic radiotherapy. PRIMARY OUTCOME: complication rate. SECONDARY OUTCOMES: incidence of and factors affecting postoperative UI. Patients were divided into 3 groups. Group 1: PV = 80-100 ml; Group 2 PV = 101-200 ml; Group 3 PV > 200 ml. Multivariable logistic regression analysis was performed to evaluate independent predictors of overall incontinence. RESULTS: There were 486 patients in Group 1, 1830 in Group 2, and 196 in Group 3. The most commonly used energy was high-power Holmium laser followed by Thulium fiber laser in all groups. Enucleation, morcellation, and total surgical time were significantly longer in Group 2. There was no significant difference in overall 30-day complications and readmission rates. Incontinence incidence was similar (12.1% in Group 1 vs. 13.2% in Group 2 vs. 11.7% in Group 3, p = 0.72). The rate of stress and mixed incontinence was higher in Group 1. Multivariable regression analysis showed that age (OR 1.019 95% CI 1.003-1.035) was the only factor significantly associated with higher odds of incontinence. CONCLUSIONS: PV has no influence on complication and UI rates following EEP. Age is risk factor of postoperative UI.

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

PURPOSE: Radical cystectomy (RC) is the standard treatment for high-risk non muscle-invasive bladder cancer (NMIBC) failing first BCG treatment. A second BCG course is an option for those patients who refuse RC or are not eligible for it, but its success rate is quite low. Aim of the present study was to determine whether the addition of intravesical electromotive drug administration of mytomicin-C (EMDA-MMC) improved the efficacy of second BCG course. METHODS: Patients with high-risk NMIBC having failed first BCG treatment and having refused RC were offered a second BCG induction course either alone (group A) or combined with EMDA-MMC (group B). Recurrence-free survival (RFS), progression-free survival (PFS) and cancer-specific survival (CSS) were tested. RESULTS: Of the 80 evaluable patients, 44 were in group A and 36 in group B; median follow-up was 38 months. RFS was significantly worse in group A whereas there was no difference in PFS and CSS between the two groups. Stratifying by disease stage, Ta patients receiving combined treatment had statistically better RFS and PFS survival than those receiving BCG only; this difference did not apply to T1 patients. Multivariable analysis confirmed that combined treatment was a significant predictor of recurrence and was close to predict progression. No tested variable was predictive of recurrence or progression in T1 tumours. Among those who underwent RC, CSS was 61.5% in those who had progression and 100% in those who remained with NMIBC. CONCLUSION: Combined treatment improved RFS and PFS only in patients with Ta disease.

RESUMEN

PURPOSE: The primary aim of this study was to evaluate if exposure to 5-alpha-reductase inhibitors (5-ARIs) modifies the effect of MRI for the diagnosis of clinically significant Prostate Cancer (csPCa) (ISUP Gleason grade ≥ 2). METHODS: This study is a multicenter cohort study including patients undergoing prostate biopsy and MRI at 24 institutions between 2013 and 2022. Multivariable analysis predicting csPCa with an interaction term between 5-ARIs and PIRADS score was performed. Sensitivity, specificity, and negative (NPV) and positive (PPV) predictive values of MRI were compared in treated and untreated patients. RESULTS: 705 patients (9%) were treated with 5-ARIs [median age 69 years, Interquartile range (IQR): 65, 73; median PSA 6.3 ng/ml, IQR 4.0, 9.0; median prostate volume 53 ml, IQR 40, 72] and 6913 were 5-ARIs naïve (age 66 years, IQR 60, 71; PSA 6.5 ng/ml, IQR 4.8, 9.0; prostate volume 50 ml, IQR 37, 65). MRI showed PIRADS 1-2, 3, 4, and 5 lesions in 141 (20%), 158 (22%), 258 (37%), and 148 (21%) patients treated with 5-ARIs, and 878 (13%), 1764 (25%), 2948 (43%), and 1323 (19%) of untreated patients (p < 0.0001). No difference was found in csPCa detection rates, but diagnosis of high-grade PCa (ISUP GG ≥ 3) was higher in treated patients (23% vs 19%, p = 0.013). We did not find any evidence of interaction between PIRADS score and 5-ARIs exposure in predicting csPCa. Sensitivity, specificity, PPV, and NPV of PIRADS ≥ 3 were 94%, 29%, 46%, and 88% in treated patients and 96%, 18%, 43%, and 88% in untreated patients, respectively. CONCLUSIONS: Exposure to 5-ARIs does not affect the association of PIRADS score with csPCa. Higher rates of high-grade PCa were detected in treated patients, but most were clearly visible on MRI as PIRADS 4 and 5 lesions. TRIAL REGISTRATION: The present study was registered at ClinicalTrials.gov number: NCT05078359.

RESUMEN

Risk calculator (RC) combining PSA with other clinical information can help to better select patients at risk of prostate cancer (PCa) for prostate biopsy. The present study aimed to develop a new Pca RC, including MRI and bladder outlet obstruction parameters (BOOP). The ability of these parameters in predicting PCa and clinically significant PCa (csPCa: ISUP GG ≥ 2) was assessed by binary logistic regression. A total of 728 patients were included from two institutions. Of these, 395 (54.3%) had negative biopsies and 161 (22.11%) and 172 (23.6%) had a diagnosis of ISUP GG1 PCa and csPCa. The two RC ultimately included age, PSA, DRE, prostate volume (pVol), post-voided residual urinary volume (PVR), and PIRADS score. Regarding BOOP, higher prostate volumes (csPCa: OR 0.98, CI 0.97,0.99) and PVR ≥ 50 mL (csPCa: OR 0.27, CI 0.15, 0.47) were protective factors for the diagnosis of any PCa and csPCa. AUCs after internal validation were 0.78 (0.75, 0.82) and 0.82 (0.79, 0.86), respectively. Finally, decision curves analysis demonstrated higher benefit compared to the first-generation calculator and MRI alone. These novel RC based on MRI and BOOP may help to better select patient for prostate biopsy after prostate MRI.

RESUMEN

Renal cancer management is challenging from diagnosis to treatment and follow-up. In cases of small renal masses and cystic lesions the differential diagnosis of benign or malignant tissues has potential pitfalls when imaging or even renal biopsy is applied. The recent artificial intelligence, imaging techniques, and genomics advancements have the ability to help clinicians set the stratification risk, treatment selection, follow-up strategy, and prognosis of the disease. The combination of radiomics features and genomics data has achieved good results but is currently limited by the retrospective design and the small number of patients included in clinical trials. The road ahead for radiogenomics is open to new, well-designed prospective studies, with large cohorts of patients required to validate previously obtained results and enter clinical practice.

RESUMEN

Traditionally, diagnosis and staging of prostate cancer (PCa) have been based on prostate-specific antigen (PSA) level, digital rectal examination (DRE), and transrectal ultrasound (TRUS) guided prostate biopsy. Biomarkers have been introduced into clinical practice to reduce the overdiagnosis and overtreatment of low-grade PCa and increase the success of personalized therapies for high-grade and high-stage PCa. The purpose of this review was to describe available PCa biomarkers and examine their use in clinical practice. A nonsystematic literature review was performed using PubMed and Scopus to retrieve papers related to PCa biomarkers. In addition, we manually searched websites of major urological associations for PCa guidelines to evaluate available evidence and recommendations on the role of biomarkers and their potential contribution to PCa decision-making. In addition to PSA and its derivates, thirteen blood, urine, and tissue biomarkers are mentioned in various PCa guidelines. Retrospective studies have shown their utility in three main clinical scenarios: (1) deciding whether to perform a biopsy, (2) distinguishing patients who require active treatment from those who can benefit from active surveillance, and (3) defining a subset of high-risk PCa patients who can benefit from additional therapies after RP. Several validated PCa biomarkers have become commercially available in recent years. Guidelines now recommend offering these tests in situations in which the assay result, when considered in combination with routine clinical factors, is likely to affect management. However, the lack of direct comparisons and the unproven benefits, in terms of long-term survival and cost-effectiveness, prevent these biomarkers from being integrated into routine clinical use.

RESUMEN

INTRODUCTION: Sacrocolpopexy (SC) is the main treatment option for the repair of anterior and apical pelvic organ prolapse (POP). Indications and technical aspects are not standardized, and the question remains whether it is necessary to place a mesh on both anterior and posterior vaginal walls, particularly in cases with only minor or no posterior compartment prolapse. The present study aimed to compare the anatomical and functional outcomes of single anterior mesh only versus anterior and posterior mesh procedures in SC. MATERIALS AND METHODS: Our prospectively maintained database on POP was used to identify patients who had undergone either abdominal or mini-invasive SC from January 2006 to October 2019. Patients with symptomatic or unmasked stress urinary incontinence (SUI) were not included in the study and were treated using the pubo-vaginal cystocele sling procedure. Objective outcomes included clinical evaluation of pre-existing or de novo POP by the halfway system and POP-q classifications, as well as the development of de novo SUI. Subjective outcomes were assessed using the Pelvic Floor Impact Questionnaire (PFIQ-7) with questions on bladder, bowel, and vaginal functions. Persistent or de novo constipation and overactive bladder were defined as bowel symptoms and urinary urgency/frequency/urinary incontinence after surgery. RESULTS: Ninety-five women with symptomatic anterior and apical POP underwent SC. Forty-one patients were treated with only anterior vaginal mesh (group A), and 54 with anterior and posterior mesh (group B). There were no differences between the pre- and post-operative characteristics of the 2 groups. In group B, there were 2 blood transfusions, 1 wound dehiscence, and 3 mesh erosions/extrusion after abdominal SC (Clavien-Dindo II), and in group A, there was 1 ileal lesion after laparoscopic SC (Clavien-Dindo III). There were no differences between the 2 groups in either anatomical or functional outcomes during 3 years of follow-up. CONCLUSIONS: SC with single anterior vaginal mesh has similar results to SC with combined anterior/posterior mesh, regardless of the surgical approach. The single anterior mesh may reduce the risk of complications (mesh erosion/extrusion), and offers better subjective outcomes with improved quality of life. Anterior/posterior mesh may be justified in the presence of clinically significant posterior POP.

RESUMEN

INTRODUCTION: The aim of the study was to systematically review the literature and describe perioperative complications of holmium laser enucleation of the prostate (HoLEP), including the Clavien-Dindo classification of surgical complications. METHODS: All English language publications on HoLEP were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines to evaluate PubMed®, Scopus®, and Web of Science™ databases from January 1, 1998, to June 1, 2020. RESULTS: Fifty-seven studies were included, for a total of 10,371 procedures. We distinguished between intra-, peri-, and postoperative complications. Overall, the rate of complications is 0-7%. Intraoperative complications include incomplete morcellation (2.3%), capsular perforation (2.2%), bladder (2.4%), and ureteric orifice (0.4%) injuries. Perioperative complications include postoperative urinary retention (0.2%), hematuria and clot retention (2.6%), and cystoscopy for clot evacuation (0.7%). Postoperative complications include dysuria (7.5%), stress (4.0%), urge (1.8%), transient (7%) and permanent (1.3%) urinary incontinence, urethral stricture (2%) and bladder neck contracture (1%). CONCLUSIONS: HoLEP is a safe procedure, with a satisfactory low complication rate. The most common reported perioperative complications are not severe (Clavien-Dindo classification grades 1-2). Further randomized studies are certainly warranted to fully determine the predictor of surgical complications in order to prevent them and improve this technique.

RESUMEN

INTRODUCTION: The association between obesity and clinically significant prostate cancer (PCa) is still a matter of debate. In this study, we evaluated the effect of body mass index (BMI) on the prediction of pathological unfavorable disease (UD), positive surgical margins (PSMs), and biochemical recurrence (BCR) in patients with clinically localized (≤cT2c) International Society of Urological Pathology (ISUP) grade group 1 PCa at biopsy. METHODS: 427 patients with ISUP grade group 1 PCa who have undergone radical prostatectomy and BMI evaluation were included. The outcome of interest was the presence of UD (defined as ISUP grade group ≥3 and pT ≥3a), PSM, and BCR. RESULTS: Statistically significant differences resulted in comparing BMI with prostate-specific antigen (PSA) and serum testosterone levels (both p < 0.0001). Patients with UD and PSM had higher BMI values (p < 0.0001 and p = 0.006, respectively). BCR-free survival was significantly decreased in patients with higher BMI values (p < 0.0001). BMI was an independent risk factor for BCR and PSM. Receiver-operating characteristic analysis testing PSA accuracy in different BMI groups, showed that PSA had a reduced predictive value (area under the curve [AUC] = 0.535; 95% confidence interval [CI] = 0.422-0.646), in obese men compared to overweight (AUC = 0.664; 95% CI = 0.598-0.725) and normal weight patients (AUC = 0.721; 95% CI = 0.660-0.777). CONCLUSION: Our findings show that increased BMI is a significant predictor of UD and PSM at RP in patients with preoperative low-to intermediate-risk diseases, suggesting that BMI evaluation may be useful in a clinical setting to identify patients with favorable preoperative disease characteristics harboring high-risk PCa.

RESUMEN

Some studies suggest a relationship between semen quality and pregnancy rates of assisted reproduction technologies (ART). Others have questioned the utility of semen quality as proxy for fertility in couples attempting to conceive with or without assistance. We aimed to investigate the current body of evidence which correlates semen parameters and clinical pregnancy among couples utilizing ART (i.e. in vitro fertilization [IVF], intracytoplasmic sperm injection [ICSI]) through a systematic review and meta-analysis of cross-sectional and retrospective cohort studies. Pooled Odd Ratio (OR) for oligo-, astheno- and teratospermic compared to normospermic number of ART cycles were calculated among. Meta-regression and sub-group analysis were implemented to model the contribution of clinical/demographic and laboratory standards differences among the studies. Overall, 17 studies were analysed representing 17,348 cycles were analysed. Pooled OR for impaired sperm concentration, motility and morphology was 1 (95%Confidence Interval [CI]: 0.97-1.03), 0.88 (95%CI: 0.73-1.03) and 0.88 (95%CI: 0.75-1) respectively. Further analysis on sperm morphology showed no differences with regard of IVF versus ICSI (p = 0.14) nor a significant correlation with rising reference thresholds (Coeff: -0.02, p = 0.38). A temporal trend towards a null association between semen parameters and clinical pregnancy was observed over the 20-year observation period (Coeff: 0.01, p = 0.014). The current analysis found no association between semen quality (as measured by concentration, motility or morphology) and clinical pregnancy rates utilizing ART. Future investigations are necessary to explore the association between semen parameters and other ART outcomes (e.g. fertilization, implantation, birth and perinatal health).

RESUMEN

BACKGROUND: Bladder cancer is the ninth most common type of cancer worldwide. In the past, radical cystectomy via open surgery has been considered the gold-standard treatment for muscle invasive bladder cancer. However, in recent years there has been a progressive increase in the use of robot-assisted laparoscopic radical cystectomy. The aim of the current project is to investigate the surgical, oncological, and functional outcomes of patients with bladder cancer who undergo radical cystectomy comparing three different surgical techniques (robotic-assisted, laparoscopic, and open surgery). Pre-, peri- and post-operative factors will be examined, and participants will be followed for a period of up to 24 months to identify risks of mortality, oncological outcomes, hospital readmission, sexual performance, and continence. METHODS: We describe a protocol for an observational, prospective, multicenter, cohort study to assess patients affected by bladder neoplasms undergoing radical cystectomy and urinary diversion. The Italian Radical Cystectomy Registry is an electronic registry to prospectively collect the data of patients undergoing radical cystectomy conducted with any technique (open, laparoscopic, robotic-assisted). Twenty-eight urology departments across Italy will provide data for the study, with the recruitment phase between 1st January 2017-31st October 2020. Information is collected from the patients at the moment of surgical intervention and during follow-up (3, 6, 12, and 24 months after radical cystectomy). Peri-operative variables include surgery time, type of urinary diversion, conversion to open surgery, bleeding, nerve sparing and lymphadenectomy. Follow-up data collection includes histological information (e.g., post-op staging, grading, and tumor histology), short- and long-term outcomes (e.g., mortality, post-op complications, hospital readmission, sexual potency, continence etc). DISCUSSION: The current protocol aims to contribute additional data to the field concerning the short- and long-term outcomes of three different radical cystectomy surgical techniques for patients with bladder cancer, including open, laparoscopic, and robot-assisted. This is a comparative-effectiveness trial that takes into account a complex range of factors and decision making by both physicians and patients that affect their choice of surgical technique.

RESUMEN

PURPOSE: To evaluate the diagnostic accuracy of SelectMDx and its association with multiparametric magnetic resonance (mpMRI) in predicting prostate cancer (PCa) and clinically significant PCa (csPCa) on prostate biopsies among men scheduled for initial prostate biopsy. METHODS: In this single-center prospective study, 52 men scheduled for initial prostate biopsy, based on elevated total PSA level (> 3 ng/ml) or abnormal digital rectal examination, were consecutively included. All subjects underwent SelectMDx, PSA determination and mpMRI. RESULTS: SelectMDx score was positive in 94.1 and 100% of PCa and csPCa, respectively, and in only 8.6% of negative cases at biopsy. The probability for a csPCa at the SelectMDx score was significantly (p = 0.002) higher in csPCa (median value 52.0%) than in all PCa (median value 30.0%). SelectMDx showed slightly lower sensitivity (94.1 versus 100.0%) but higher specificity (91.4%) than total PSA (17.1%), and the same sensitivity but higher specificity than mpMRI (80.0%) in predicting PCa at biopsy. The association of SelectMDx plus mpMRI rather than PSA density (PSAD) plus mpMRI showed higher specificity (both 91.4%) compared to the association of PSA plus mpMRI (85.7%). In terms of csPCa predictive value, SelectMDx showed higher specificity (73.3%) than PSA (13.3%) and mpMRI (64.4%); as for the association of SelectMDx plus mpMRI (75.6%) versus PSA plus mpMRI (68.9%), the association of PSAD plus mpMRI showed the highest specificity (80.0%). CONCLUSION: Our results of SelectMDx can be confirmed as significant but their impact on clinical practice together with a cost-effectiveness evaluation should be investigated in a larger prospective multicenter analysis.

RESUMEN

PURPOSE: To determine the need for routine bladder biopsies (BBs) in assessing response to the induction cycle of intravesical bacillus Calmette-Guérin (BCG) for high-risk non-muscle-invasive bladder cancer (NMIBC). METHODS: Our prospectively maintained NMIBC database was queried to identify patients with high-risk disease (carcinoma in situ, high-grade Ta/T1) who underwent BBs after BCG induction cycle. Urine cytology, cystoscopy, and BBs findings were evaluated. RESULTS: A total of 219 patients met the inclusion criteria. Urine cytology was positive in 20 patients and negative in 199; cystoscopy was positive in 35 patients, suspicious in 32 and normal in 152 patients. BBs yielded bladder cancer (BCa) in 43 (19.6%) patients, with a BCa rate of 9.3% in patients with negative cytology and cystoscopy as opposed to 38.0% in patients whereby one or both exams were suspicious/positive. The diagnostic accuracy of urine cytology, cystoscopy, and combined tests was 0.56, 0.70, and 0.71, respectively. The negative predictive value of combined tests was 90.7%. Performing BBs only in patients with positive cytology and/or positive/suspicious cystoscopy would have spared 140 (64%) patients to undergo this procedure while missing BCa in 13 (9.3%) of them, representing 30% of all BCa cases. CONCLUSION: Performing BBs only in patients with positive cytology and suspicious/positive cystoscopy would spare 64% of un-necessary BBs but miss a non-negligible number of BCas. While no data are available regarding the potential consequences of missing such BCas, such information should be taken into account in patient's counselling.

RESUMEN

PURPOSE: The association between circulating total testosterone (T) levels and clinically significant PCa is still a matter of debate. In this study, we evaluated whether serum testosterone levels may have a role in predicting unfavorable disease (UD) and biochemical recurrence (BCR) in patients with clinically localized (≤ cT2c) ISUP grade group 1 PCa at biopsy. METHODS: 408 patients with ISUP grade group 1 prostate cancer, undergone to radical prostatectomy and T measurement were included. The outcome of interest was the presence of unfavourable disease (UD) defined as ISUP grade group [Formula: see text] 3 and/or pT [Formula: see text] 3a. RESULTS: Statistically significant differences resulted between serum testosterone values and ISUP grade groups (P < 0.0001). Significant correlation was found analyzing testosterone values versus age (P < 0.0001), and versus PSA (P = 0.008). BCR-free survival was significantly decreased in patients with low levels of testosterone (P = 0.005). These findings were confirmed also in the ISUP 1-2 subgroups (P = 0.01). ROC curve analysis showed that T outperformed PSA in predicting UD (AUC 0.718 vs AUC 0.525; P < 0.001) and was and independent risk factor for BCR. CONCLUSION: Our findings suggested that circulating total T was a significant predictor of UD at RP in patients with preoperative low- to intermediate-risk diseases, confirming the potential role of circulating androgens in preoperative risk assessment of PCa patients.

RESUMEN

PURPOSE: Diagnosis of anterior prostate cancer (PCa) can be quite challenging, often leading to delay in treatment. mpMRI-guided biopsy (GB) has been introduced aiming to increase the number of diagnoses of clinically significant PCa with fewer cores. The aim of our study is to compare pathological findings of prostate biopsy, In-bore or Fusion technique, with histopathological evaluation of radical prostatectomy. METHODS: We prospectively collected data from 90 consecutive patients who underwent either In-bore or Fusion biopsy following the detection of an index suspicious lesion at mpMRI in the anterior part of the prostatic gland. Bioptical pathological findings were compared with pathological findings reported after robot-assisted radical prostatectomy. RESULTS: Patients who underwent In-bore GB had a higher rate of previous negative prostate biopsies (19% vs 44%, p = 0.02). Median number of bioptic cores taken (13 vs 2) and number of positive cores (3 vs 2) were significantly superior in the Fusion group compared to the In-bore group (p < 0.001 and p = 0.002, respectively), whilst clinical International Society of Urological Pathology (ISUP) grade was homogeneous within groups. The concordance between anterior lesions detected at biopsy and those reported in the histopathological finding of radical prostatectomy was very high, without statistically significant difference between groups. CONCLUSION: Both Fusion and In-bore GB are accurate in detecting anterior PCa, with enhanced precision detecting clinically significant tumours, as evidenced by pathologic examinations which confirmed the presence of index anterior PCa in > 50% of patients overall. Additional sextant biopsy is still required, especially among biopsy-näive patients, to avoid missing clinically significant PCa.

RESUMEN

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.

RESUMEN

OBJECTIVE: To provide an updated systematic review of randomized control trials (RCTs) to investigate the clinical and microbiological efficacy of nitrofurantoin compared to other antibiotics or placebo for treatment of uncomplicated urinary tract infections (uUTI). A secondary aim is to assess whether nitrofurantoin use is associated with increased side effects compared to other treatment regimens. SUMMARY: The review was performed according to PRISMA guidelines. We searched 4 databases for articles published from database inception to May 6, 2020: (1) PubMed electronic database of the National Library of Medicine, (2) Web of Science, (3) Embase, and (4) Cochrane Library. Nine RCTs were selected for the review. RCTs were a mixture of double-blind, single-blind, and open-label trials. The most common comparators were trimethoprim-sulfamethoxazole and fosfomycin tromethamine. Overall study quality was poor with a high risk of bias. The clinical cure rates in nitrofurantoin ranged from 51 to 94% depending on the length of follow-up, and bacteriological cure rates ranged from 61 to 92%. Overall the evidence suggests that nitrofurantoin is at least comparable with other uUTI treatments in terms of efficacy. Patients taking nitrofurantoin reported fewer side effects than other drugs and the most commonly reported were gastrointestinal and central nervous system symptoms. Key Messages: Evidence on the clinical and bacteriological efficacy of nitrofurantoin is sparse, with a lack of new data, and hampered by high risk of bias. Although no firm conclusions can be made on the current base of evidence, the studies generally suggest that nitrofurantoin is at least comparable to other common uUTI treatments in terms of clinical and bacteriological cure. More robust research with well-designed double-blinded RCTs is needed.
