The effect of neoadjuvant chemotherapy among patients undergoing radical cystectomy for variant histology bladder cancer: A systematic review

Objective: To systematically review the evidence about the effect of neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) with pure urothelial carcinoma (pUC) in radical cystectomy (RC) candidates affected by variant histology (VH) bladder cancer. Methods: A review of the current literature was conducted through the Medline and National Center for Biotechnology Information (NCBI) PubMed, Scopus databases in May 2020. The updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed for this systematic review. Keywords used were ‘bladder cancer’, ‘bladder carcinoma’, ‘bladder tumour’ and ‘bladder cancer variants’ and ‘neoadjuvant chemotherapy’. Only original articles in English published after 2000 and reporting oncological outcomes a series of more than five patients with VH were included. We excluded series in which the oncological outcomes of patients with pUC and VH were undistinguishable. Results: The literature search identified 2231 articles. A total of 51 full-text articles were assessed for eligibility, with 17 eventually considered for systematic review, for a cohort of 450,367 patients, of which 5010 underwent NAC + RC. The median age at initial diagnosis ranged from 61 to 71 years. Most patients received cisplatin-gemcitabine, methotrexate-vinblastine-adriamycin-cisplatin, or carboplatin-based chemotherapy. Only one study reported results of neoadjuvant immunotherapy. The median follow-up ranged from 1 to 120 months. The results showed that squamous cell carcinoma (SCC) is less sensitive to NAC than pUC and that SCC predicts poorer prognosis. NAC was found to be a valid approach in treating small cell carcinoma and may have potential benefit in micropapillary carcinoma. Conclusions: NAC showed the best oncological outcomes in small cell variants and micropapillary carcinoma, while NAC survival benefit for SCC and adenocarcinoma variants needs further studies. Drawing definite considerations on the efficacy of NAC in VH is complicated due to the heterogeneity of present literature. Present results need to be confirmed in randomised controlled trial

Patients' perceptions of quality of care delivery by urology residents: A nationwide study

Objective To present the results of a nationwide survey among urological patients to evaluate their perception of the quality of care provided by residents. Methods An anonymous survey was distributed to patients who were referred to 22 Italian academic institutions. The survey aimed to investigate the professional figure of the urology resident as perceived by the patient. Results A total of 2587 patients were enrolled in this study. In all, 51.6% of patients were able to correctly identify a urology resident; however, almost 40% of respondents discriminated residents from fully trained urologists based exclusively on their young age. Overall, 98.2% patients rated the service provided by the resident as at least sufficient. Urology trainees were considered by more than 50% of the patients interviewed to have good communication skills, expertise and willingness. Overall, patients showed an excellent willingness to be managed by urology residents. The percentage of patients not available for this purpose showed an increasing trend that directly correlated with the difficulty of the procedure. Approximately 5-10% of patients were not willing to be managed by residents for simple procedures such as clinical visits, cystoscopy or sonography, and up to a third of patients were not prepared to undergo any surgical procedure performed by residents during steps in major surgery, even if the residents were adequately tutored. Conclusions Our data showed that patients have a good willingness to be managed by residents during their training, especially for medium- to low-difficulty procedures. Furthermore, the majority of patients interviewed rated the residents' care delivery as sufficient. Urology trainees were considered to have good communication skills, expertise and willingness

Sexuality during COVID lockdown: a cross-sectional Italian study among hospital workers and their relatives

In March 2020, the Italian Government introduced measures to reduce the spread of COVID-19 infection. Between 8th April and 2nd May 2020 we investigated levels and correlates of sexual activity and depression during COVID-19 lockdown in a sample of hospital workers and their acquaintances by an online survey on SurveyMonkey. Socio-demographic data, International Index of Erectile Function, Female Sexual Function Index, and Beck Depression Inventory were recorded. Multivariable logistic regression analysis (MLRA) was used to test predictors of depressive symptoms and low sexual desire and satisfaction. A statistically significant difference in age, change in working habit, sexual satisfaction, sexual desire, and depressive symptoms was found between males and females. A statistically significant higher proportion of health care workers had low sexual desire (65.3% vs 56.8%, p = 0.042). At MLRA, age, being female, being a health care worker, having children at home, living with the partner, and having low sexual satisfaction were predictors of low level of sexual desire. To our knowledge, this is one of the few studies using validated questionnaires for both males and females to assess sexual well-being and psychometric alterations during COVID quarantine

The fight between PCNL, laparoscopic and robotic pyelolithotomy: do we have a winner? A systematic review and meta-analysis

INTRODUCTION The aim of this systematic review and meta-analysis was to provide an updated comparison between the currently available minimally invasive approaches (PCNL, laparoscopic [LP] and robotic pyelolithotomy [RP]) for the management of large renal stones. EVIDENCE ACQUISITION An electronic search of the current literature was conducted through the Medline and NCBI PubMed, Embase, Scopus and Cochrane Collaboration Central Register of Controlled Clinical Trials databases in March 2021. Studies about minimally-invasive treatment for kidney stones were considered. Inclusion criteria were: studies evaluating patients with large renal calculi (≥2 cm); the comparison of at least two of the three approaches (PCNL, LP, RP), and reporting data suitable for meta-analysis evaluation. Patients with concomitant management for ureteropelvic junction obstruction (UPJ-O) were excluded. EVIDENCE SYNTHESIS Overall, 17 reports were considered for qualitative and quantitative synthesis, for a total cohort of 1079 patients, of which 534 with PCNL, 525 treated with LP, and 20 with RP. Of those, 16 compared PCNL with LP, while only 1 study compared LP with RP. PCNL mean operative time was statistically significantly shorter than LP and RP while mean estimated blood loss was statistically significantly higher for PNCL. No statistically significant differences were recorded among the three surgical approaches. Finally, PCNL demonstrated slightly, albeit statistically significant lower stone free rate when compared with LP. CONCLUSIONS PCNL, LP and RP may be safely and efficiently used to manage large renal stones. All three procedures showed reasonably low rate of complications with a satisfactory stone clearance rate

The impact of visceral adipose tissue on postoperative renal function after radical nephrectomy for renal cell carcinoma

BACKGROUND: The objective of this study was to evaluate the usefulness of pre-operative visceral (VAT) and subcutaneous adipose tissue (SAT) evaluation in the prediction of acute kidney injury (AKI) and decrease of eGFR at 12 months after radical nephrectomy (RN).METHODS: We relied on 112 patients who underwent RN between January 2010 and March 2017 at a single institution. Images from the pre-operatory CT scan were analyzed and both SAT and VAT assessments were carried out on a cross-sectional plane. eGFR was measured before surgery, at 7 days, and 12 months after surgery. ROC analysis was used to compare the diagnostic value of BMI, VAT ratio, and abdominal circumference in predicting AKI. Logistic regression models were fitted to predict the new onset of AKI, and the progression from chronic kidney disease (CKD) stage 1-3a to CKD stage 3b or from 3b to 4 at 12 months follow-up. Two logistic regression models were also performed to assess the predictors for AKI and CKD stage progression. The predictive accuracy was quantified using the receiver operating characteristic-derived area under the curve.RESULTS: Sixty-six patients (58.9%) had AKI after RN. Thirty-five (31.3%) patients were upgraded to CKD IIIb or from CKD stage IIIb to CKD IV. In the ROC analysis, VAT% performed better than the BMI and abdominal circumference (AUC=0.66 vs. 0.49 and 0.54, respectively). At multivariable analyses, VAT reached an independent predictor status for AKI (OR: 1.03) and for CKD stage at 12-month follow-up (OR: 1.05). Inclusion of VAT% into the multivariable models was associated with the highest accuracy both for AKI (AUC=0.700 vs. 0.570) and CKD stage progression (AUC=0.848 vs. 0.800).CONCLUSIONS: In patients undergoing RN, preoperative visceral adipose tissue ratio significantly predicts AKI incidence and is significantly predictive of 12-month CKD stage worsening

Radical cystectomy in bladder cancer patients previously treated for prostate cancer: Insights from a large European multicentric series

Introduction: Previous radical prostatectomy (RP) for prostate cancer (PCa) might impair feasibility of radical cystectomy (RC) for bladder cancer (BCa). The current study addressed morbidity, operative time (OT), and length of stay (LOS) of RC, within the largest available series of patients with history of previous RP.Materials and methods: All patients previously submitted to RP for PCa and subsequently submitted to RC for BCa, at six high-volume European institutions between 2010 and 2019, were identified. Presence of either PCa or BCa metastases, RT as primary treatment for PCa, and palliative RC represented exclusion criteria. The quality criteria for accurate and comprehensive reporting of intra-and post-operative surgical outcomes, recommended by the European Association of Urology guidelines, were fulfilled. Multivariable logistic and Poisson regression analyses were performed.Results: Overall, 140 RC patients with history of RP were identified. After RP, 69 (49%) patients received radiotherapy (RT) for PCa, either in adjuvant (n = 50, 36%) or salvage setting (n = 19, 13%). Median age -adjusted Charlson comorbidity index was 6 (IQR 5, 7). Median OT, estimated blood loss and LOS were, respectively, 300 min, 500 ml, and 16 days. Intra-operative transfusions rate was 47% (n = 65). One intra-operative complication occurred (EAUiaiC grade 2, perforation of the rectum managed with immediate repair). Eighty-two (59%) patients experienced a total of 107 post-operative complications during the hospital stay, and seven (5%) patients required hospital readmission. In multivariable regression analyses, RT for PCa was associated with higher risk of post-operative complications (odds ratio 1.82, p = 0.039), longer OT (incidence rate ratio 1.09, p < 0.001), and longer LOS (incidence rate ratio 1.24, p < 0.001).Conclusions: RC in patients with history of RP is feasible, albeit burdened by remarkable morbidity, even in centers of excellence. RT after RP for PCa portends worse surgical outcomes

Non‐cancer mortality in elderly prostate cancer patients treated with combination of radical prostatectomy and external beam radiation therapy

Background: To test for rates of other cause mortality (OCM) and cancer-specific mortality (CSM) in elderly prostate cancer (PCa) patients treated with the combination of radical prostatectomy (RP) and external beam radiation therapy (EBRT) versus RP alone, since elderly PCa patients may be over-treated. Methods: Within the Surveillance, Epidemiology and End Results database (2004–2016), cumulative incidence plots, after propensity score matching for cT-stage, cN-stage, prostate specific antigen, age and biopsy Gleason score, and multivariable competing risks regression models (socioeconomic status, pathological Gleason score) addressed OCM and CSM in patients (70–79, 70–74, and 75–79 years) treated with RP and EBRT versus RP alone. Results: Of 18,126 eligible patients aged 70–79 years, 2520 (13.9%) underwent RP and EBRT versus 15,606 (86.1%) RP alone. After propensity score matching, 10-year OCM rates were respectively 27.9 versus 20.3% for RP and EBRT versus RP alone (p < .001), which resulted in a multivariable HR of 1.4 (p < .001). Moreover, 10-year CSM rates were respectively 13.4 versus 5.5% for RP and EBRT versus RP alone. In subgroup analyses separately addressing 70–74 year old and 75–79 years old PCa patients, 10-year OCM rates were 22.8 versus 16.2% and 39.5 versus 24.0% for respectively RP and EBRT versus RP alone patients (all p < .001). Conclusion: Elderly patients treated with RP and EBRT exhibited worrisome rates of OCM. These higher than expected OCM rates question the need for combination therapy (RP and EBRT) in elderly PCa patients and indicate the need for better patient selection, when combination therapy is contemplated

Assessment of the optimal number of positive biopsy cores to discriminate between cancer-specific mortality in high-risk versus very high-risk prostate cancer patients

Background: Number of positive prostate biopsy cores represents a key determinant between high versus very high-risk prostate cancer (PCa). We performed a critical appraisal of the association between the number of positive prostate biopsy cores and CSM in high versus very high-risk PCa. Methods: Within Surveillance, Epidemiology, and End Results database (2010–2016), 13,836 high versus 20,359 very high-risk PCa patients were identified. Discrimination according to 11 different positive prostate biopsy core cut-offs (≥2–≥12) were tested in Kaplan–Meier, cumulative incidence, and multivariable Cox and competing risks regression models. Results: Among 11 tested positive prostate biopsy core cut-offs, more than or equal to 8 (high-risk vs. very high-risk: n = 18,986 vs. n = 15,209, median prostate-specific antigen [PSA]: 10.6 vs. 16.8 ng/ml, <.001) yielded optimal discrimination and was closely followed by the established more than or equal to 5 cut-off (high-risk vs. very high-risk: n = 13,836 vs. n = 20,359, median PSA: 16.5 vs. 11.1 ng/ml, p < .001). Stratification according to more than or equal to 8 positive prostate biopsy cores resulted in CSM rates of 4.1 versus 14.2% (delta: 10.1%, multivariable hazard ratio: 2.2, p < .001) and stratification according to more than or equal to 5 positive prostate biopsy cores with CSM rates of 3.7 versus 11.9% (delta: 8.2%, multivariable hazard ratio: 2.0, p < .001) in respectively high versus very high-risk PCa. Conclusions: The more than or equal to 8 positive prostate biopsy cores cutoff yielded optimal results. It was very closely followed by more than or equal to 5 positive prostate biopsy cores. In consequence, virtually the same endorsement may be made for either cutoff. However, more than or equal to 5 positive prostate biopsy cores cutoff, based on its existing wide implementation, might represent the optimal choice
