EAU-ESMO consensus statements on the management of advanced and variant bladder cancer-an international collaborative multi-stakeholder effort: under the auspices of the EAU and ESMO Guidelines Committees†.

BACKGROUND: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts before voting during a consensus conference. SETTING: Online Delphi survey and consensus conference. PARTICIPANTS: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS: Overall, 116 statements were included in the Delphi survey. Of these, 33 (28%) statements achieved level 1 consensus and 49 (42%) statements achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease and the evolving role of checkpoint inhibitor therapy in metastatic disease. CONCLUSIONS: These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time where further evidence is available to guide our approach.

Salvage lymphadenectomy in recurrent prostate cancer: is there evidence of real benefit?

PURPOSE: Nodal recurrent prostate cancer (PCa) after primary radical treatment represents a heterogeneous entity with many treatment options. In some cases, surgical removal of metastatic nodes seems to improve cancer control and delay systemic treatments. The objectives of this study were to analyze the available literature on salvage lymphadenectomy for the treatment of nodal recurrent PCa and to elucidate the real oncological benefit deriving from this procedure. METHODS: A PubMed search was performed using the following terms: prostate cancer, metastatic, oligometastatic, salvage lymphadenectomy, salvage lymph node dissection, salvage lymph node excision, and cytoreductive surgery. We included in the study all papers on salvage lymphadenectomy in nodal recurrent PCa, with no temporal limits. In addition, several papers addressing cytoreductive surgery and the biology of oligometastatic disease, published in different medical and basic research journals, were included. RESULTS: Salvage lymphadenectomy is still characterized by a lack of standardization in patient selection and surgical template. Its primary objectives are to prolong progression-free survival and to delay the need for systemic therapy. The improvements in preoperative imaging techniques in conjunction with the wide use of minimally invasive surgery have generated growing interest in this procedure. CONCLUSION: Salvage lymphadenectomy is a promising treatment approach; however, its real oncological benefit is still far from proven. Prospective randomized trials need to be designed to improve understanding of this issue.

Updates on intravesical therapy.

PURPOSE OF REVIEW: To review the current literature concerning the intravesical treatment of nonmuscle invasive bladder cancer. RECENT FINDINGS: Bladder cancer is a high prevalent disease. Despite the recognized efficacy of traditional intravesical therapies, the best treatment strategy still needs to be found. Improvement in bladder cancer research lead to develop new intravesical agents and drug delivery systems for nonmuscle invasive bladder cancer tumours. Moreover, the emerging knowledge of bladder cancer immune profile strongly improves and provides new available treatment strategies. SUMMARY: The future of nonmuscle invasive bladder cancer therapy will be influenced by the development of immunotherapy and new technologies for device-assisted treatment. Moreover, nanotechnology and delivery systems present promising results.

Live surgery: highly educational or harmful?

PURPOSE: Live surgery (LS) is considered a useful teaching opportunity. The benefits must be balanced with patient safety concerns. To evaluate the rate of complications of a series of urologic LS performed by experts during the Congress Challenge in Laparoscopy and Robotics (CILR). METHODS: We present a large, multi-institution, multi-surgeon database that derives from 12 CILR events, from 2004 to 2015 with a total of 224 cases. Radical prostatectomy (RP) was the most common procedure and a selection of complex cases was noted. The primary measure was postoperative complications and use of a Postoperative Morbidity Index (PMI) to allow quantitative weighing of postoperative complications. RESULTS: From 12 events, the number of cases increased from 11 in 2004 to 27 in 2015 and a total of 27 surgeons. Of 224 cases (164 laparoscopic and 60 robotic), there were 26 (11.6%) complications: 5 grade I, 5 grade II, 3 grade IIIa, 12 grade IIIb and 1 grade V, the latter from laparoscopic cystectomy. Analysis of PMI was 23 times higher from cystectomy compared to RP. CONCLUSIONS: In the setting of live surgery, the overall rate of complications is low considering the complexity of surgeries. The PMI is not higher in more complex procedures, whereas RP seems very safe.

Predictors of oncological outcomes in T1G3 patients treated with BCG who undergo radical cystectomy.

PURPOSE: To evaluate the oncological impact of postponing radical cystectomy (RC) to allow further conservative therapies prior to progression in a large multicentre retrospective cohort of T1-HG/G3 patients initially treated with BCG. METHODS: According to the time of RC, the population was divided into 3 groups: patients who did not progress to muscle-invasive disease, patients who progressed before radical cystectomy and patients who experienced progression at the time of radical cystectomy. Clinical and pathological outcomes were compared across the three groups. RESULTS: Of 2451 patients, 509 (20.8%) underwent RC. Patients with tumors > 3 cm or with CIS had earlier cystectomies (HR = 1.79, p = 0.001 and HR = 1.53, p = 0.02, respectively). Patients with tumors > 3 cm, multiple tumors or CIS had earlier T3/T4 or N + cystectomies. In patients who progressed, the timing of cystectomy did not affect the risk of T3/T4 or N + disease at RC. Patients with T3/T4 or N + disease at RC had a shorter disease-specific survival (HR = 4.38, p < 0.001), as did patients with CIS at cystectomy (HR = 2.39, p < 0.001). Patients who progressed prior to cystectomy had a shorter disease-specific survival than patients for whom progression was only detected at cystectomy (HR = 0.58, p = 0.024) CONCLUSIONS: Patients treated with RC before experiencing progression to muscle-invasive disease harbor better oncological and survival outcomes compared to those who progressed before RC and to those upstaged at surgery. Tumor size and concomitant CIS at diagnosis are the main predictors of surgical treatment while tumor size, CIS and tumor multiplicity are associated with extravesical disease at surgery.

Recurrence, progression and cancer-specific mortality according to stage at re-TUR in T1G3 bladder cancer patients treated with BCG: not as bad as previously thought.

PURPOSE: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis to adequately stage and treat the patient. Persistent disease after TUR is not uncommon and is why re-TUR is recommended in T1G3 patients. When there is T1 tumor in the re-TUR specimen, very high risks of progression (82%) have been reported. We analyze the risks of recurrence, progression to muscle-invasive disease and cancer-specific mortality (CSM) according to tumor stage at re-TUR in T1G3 patients treated with BCG. METHODS: In our retrospective cohort of 2451 T1G3 patients, 934 patients (38.1%) underwent re-TUR. 667 patients had residual disease (71.4%): Ta in 378 (40.5%), T1 in 289 (30.9%) patients. Times to recurrence, progression and CSM in the three groups were estimated using cumulative incidence functions and compared using the Cox regression model. RESULTS: During a median follow-up of 5.2 years, 512 patients recurred. The recurrence rate was significantly higher in patients with a T1 at re-TUR (P < 0.001). Progression rates differed according to the pathology at re-TUR, 25.3% in T1, 14.6% in Ta and 14.2% in case of no residual tumor (P < 0.001). Similar trends were seen in both patients with and without muscle in the original TUR specimen. CONCLUSIONS: Patients with T1G3 tumors and no residual disease or Ta at re-TUR have better recurrence, progression and CSM rates than previously reported, with a CSM rate of 13.1 and a 25.3% progression rate in re-TUR T1 disease.

Update of the ICUD-SIU consultation on upper tract urothelial carcinoma 2016: treatment of low-risk upper tract urothelial carcinoma.

INTRODUCTION: The conservative management of upper tract urothelial carcinoma (UTUC) has historically been offered to patients with imperative indications. The recent International Consultation on Urologic Diseases (ICUD) publication on UTUC stratified treatment allocations based on high- and low-risk groups. This report updates the conservative management of the low-risk group. METHODS: The ICUD for low-risk UTUC working group performed a thorough review of the literature with an assessment of the level of evidence and grade of recommendation for a variety of published studies in this disease space. We update these publications and provide a summary of that original report. RESULTS: There are no prospective randomized controlled studies to support surgical management guidelines. A risk-stratified approach based on clinical, endoscopic, and biopsy assessment allows selection of patients who could benefit from kidney-preserving procedures with oncological outcomes potentially similar to radical nephroureterectomy with bladder cuff excision, with the added benefit of renal function preservation. These treatments are aided by the development of high-definition flexible digital URS, multi-biopsies with the aid of access sheaths and other tools, and promising developments in the use of adjuvant topical therapy. CONCLUSIONS: Recent developments in imaging, minimally invasive techniques, multimodality approaches, and adjuvant topical regimens and bladder cancer prevention raise the hope for improved risk stratification and may greatly improve the endoscopic treatment for low-risk UTUC.

Kidney cancer focal cryoablation trend: does location or approach matter?

PURPOSE: We evaluated the current indications and surgical and survival outcomes for cryoablation (CA) using either a percutaneous (PCA) or a laparoscopic approach (LCA). We also investigated the ability of the PADUA score to predict the risk of complications and local recurrence. METHODS: A retrospective analysis was performed at two European tertiary referral centers. Parameters analyzed included size, location, approach, operative time, hospital stay, complications, and functional and oncologic outcomes. Univariate and multivariate analyses were performed. An ROC analysis was conducted to evaluate the accuracy of the PADUA score. RESULTS: Eighty patients were included. Mean tumor size was 2.6 cm. PCA was more often performed in posterior (95 vs. 60 %), inferior (72 vs. 32 %), and lateral (87 vs. 55 %) tumors. The global complication rate was 8.75 %, although proximity to the renal sinus resulted in a higher rate (30 vs. 4 %). Mean follow-up was 34 and 23 months for LCA and PCA, respectively. The 5-year recurrence-free survival was 76 and 90 % for LCA and PCA, respectively. Multivariate analysis showed that tumor involvement of the collecting system was predictive of recurrence. Under ROC analysis, PADUA score was a mild predictor for complications (AUC = 0.601) and a good predictor for recurrence (AUC = 0.723); PADUA ≥8 was identified as a cutoff for patients to a higher risk of recurrence. CONCLUSIONS: The percutaneous approach is confirmed to be the preferred CA technique for posterior and lateral tumors. CA in deeper renal lesions and tumors with PADUA score ≥8 might entail a higher risk of recurrence, and closer follow-up should be considered in these patients.

Dermoscopy structures as predictors of sentinel lymph node positivity in cutaneous melanoma.

BACKGROUND: Histological features such as Breslow thickness, ulceration and mitosis are the main criteria to guide sentinel lymph node biopsy (SLNB) in melanoma. Dermoscopy may add complementary information to these criteria. OBJECTIVES: To evaluate the correlation between dermoscopy structures and SLNB positivity. METHODS: Retrospective analysis of 123 consecutive melanomas with Breslow thickness > 0·75 mm, SLNB performed during follow-up and dermoscopic images. RESULTS: Men were more likely to have a positive SLNB. The presence of ulceration and blotch and the absence of a pigmented network in dermoscopy correlated with positive SLNB. Histological ulceration also correlated with positive SLNB. A dermoscopy SCORE predicted SLN status with a sensitivity of 96·3% and a specificity of 30·2%. When sex and Breslow thickness were added (SCOREBRESEX), the sensitivity remained at 96·3% but the specificity increased to 52·1%. This study is limited by the number of patients and was performed in only one institution. CONCLUSIONS: Dermoscopy allowed a more precise prediction of SLN status. If a combined SCOREBRESEX was used to select patients for SLNB, 41·5% of procedures might be avoided.

Bladder cancer in Spain 2011: population based study.

PURPOSE: We estimate the annual incidence of bladder cancer in Spain and describe the clinical profile of patients with bladder cancer enrolled in a population based study. MATERIALS AND METHODS: Using the structure of the Spanish National Health System as a basis, in 2011 the AEU (Spanish Association of Urology) conducted this study with a representative sample from 26 public hospitals and a reference population of 10,146,534 inhabitants, comprising 21.5% of the Spanish population. RESULTS: A total of 4,285 episodes of bladder cancer were diagnosed, of which 2,476 (57.8%) were new cases and 1,809 (42.2%) were cases of recurrence, representing an estimated 11,539 new diagnoses annually in Spain. The incidence of bladder cancer in Spain, age adjusted to the standard European population, was 20.08 cases per 100,000 inhabitants (95% CI 13.9, 26.3). Of patients diagnosed with a first episode of bladder cancer 84.3% were male, generally older than 59 years (81.7%) with a mean ± SD age of 70.5 ± 11.4 years. Of these patients 87.5% presented with some type of clinical symptom, with macroscopic hematuria (90.8%) being the most commonly detected. The majority of primary tumors were nonmuscle invasive (76.7%) but included a high proportion of high grade tumors (43.7%). According to the ISUP (International Society of Urologic Pathology)/WHO (2004) classification 51.1% was papillary high grade carcinoma. Carcinoma in situ was found in 2.2% of primary and 5.8% of recurrent cases. CONCLUSIONS: The incidence of bladder cancer in Spain, age adjusted to the standard European population, confirms that Spain has one of the highest incidences in Europe. Most primary nonmuscle invasive bladder cancer corresponded to high risk patients but with a low detected incidence of carcinoma in situ.

Impact of in vivo reflectance confocal microscopy on the number needed to treat melanoma in doubtful lesions.

BACKGROUND: The number needed to treat (NNT) ratio is an effective method for measuring accuracy in melanoma detection. Dermoscopy reduces the number of false positives and subsequently unnecessary excisions. In vivo reflectance confocal microscopy (RCM) is a noninvasive technique that allows examination of the skin with cellular resolution. OBJECTIVES: To assess the impact of RCM analysis on the number of equivocal lesions, assumed to be melanocytic, excised for every melanoma. METHODS: Consecutive patients (n = 343) presenting with doubtful lesions were considered for enrolment. The lesions were analysed by dermoscopy and RCM, with histopathological assessment considered the reference standard. The main outcome was the NNT, calculated as the proportion of equivocal lesions excised for every melanoma. RESULTS: Dermoscopy alone obtained a hypothetical NNT of 3·73; the combination of dermoscopy and RCM identified 264 equivocal lesions that qualified for excision, 92 of which were confirmed to be a melanoma, resulting in an NNT of 2·87, whereas the analysis of RCM images classified 103 lesions as melanoma, with a consequent NNT of 1·12. The difference in the reduction of this ratio was statistically significant between the three groups (P < 0·0001). There was no significant improvement in sensitivity when comparing the combination of dermoscopy and RCM with RCM alone (94·6% vs. 97·8%; P = 0·043). However, the differences between specificities were statistically significant (P < 1 × 10(-6) ), favouring RCM alone. CONCLUSION: The addition of RCM analysis to dermoscopy reduces unnecessary excisions with a high diagnostic accuracy and could be a means for reducing the economic impact associated with the management of skin cancer.

Predictive factors for impaired renal function following nephroureterectomy in upper urinary tract urothelial cell carcinoma.

OBJECTIVES: Despite the uncertain value of adjuvant chemotherapy after radical nephroureterectomy (RNU) it is clear that impaired renal function represents a contraindication to its administration. The objective of this study was to identify possible predictive clinical factors for impaired renal function following RNU in patients with upper urinary tract urothelial cell carcinoma (UUT-UCC). PATIENTS AND METHODS: A retrospective analysis was conducted of 546 patients who underwent RNU between 1992 and 2008 at our institution. Data of interest for this study included estimated glomerular filtration rate (eGFR), age, pathological stage and preoperative hydronephrosis (HN). The predictive value of HN, age and pathological stage for impaired renal function after RNU was calculated by multivariate linear regression analysis. RESULTS: In total, 138 patients met the criteria for inclusion, including 108 men (78%). Mean age at surgery was 67 ± 10 years. There was a significant correlation (p < 0.001) between pre- and postoperative eGFR (decrease of 21% after NU). Preoperative HN was present in 51 patients (37%). On linear regression analysis, preoperative eGFR ≤60 ml/min (p = 0.012; OR = 4.60) and HN (p = 0.027; OR = 10.34) were confirmed to be predictive factors for a postoperative eGFR ≤60 ml/min. When postoperative eGFR ≤45 ml/min was used as the criterion for impaired renal function, predictive factors proved to be preoperative eGFR ≤45 ml/min (p < 0.0001; OR = 18.53), HN (p = 0.038; OR = 0.380) and age ≥70 years (p < 0.0001; OR = 0.169). CONCLUSIONS: Preoperative HN, older age and preoperative eGFR <60 ml/min were proven to be predictive factors for impaired renal function after RNU. In these settings, neoadjuvant chemotherapy may be considered.

Cumulative morbidity of ureteroscopy for upper tract urothelial carcinoma.

OBJECTIVE: To assess complications after ureteroscopy (URS) for upper tract urothelial carcinoma (UTUC) management and to assess its postoperative cumulative morbidity burden using the Comprehensive Complication Index (CCI). MATERIALS AND METHODS: Single center retrospective study including patients submitted to URS for UTUC suspicion. URSs were both diagnostic and operative. Postoperative complications were recorded according to the EAU Guidelines and graded according to Clavien-Dindo Classification (CDC). The cumulative postoperative morbidity burden developed by patients experiencing multiple events was assessed using the CCI. Multivariable logistic regression (MLR) analyses identified factors independently associated with the development of any grade and major postoperative complications. RESULTS: Overall, 360 patients with UTUC suspicion were included with a total of 575 URSs performed. The cumulative number of all postoperative complications recorded was 111. In 86 (15%) procedures, patients experienced at least one postoperative complication, while 25 (4.3%) experienced more than one complication. Of these, 16 (14%) were severe (CDC ≥ IIIa). The most frequent type of complications were urinary (34%), bleeding (30%) and infectious (30%). The higher the CDC grade, the higher the median CCI, with a statistically significant increase in median CCI from CDC II to major complications. Patients who experienced intraoperative complications were at higher risk of developing any grade and major postoperative complications at MLR. CONCLUSIONS: Complications after ureteroscopy for UTUC are relatively uncommon events. Patients who experience intraoperative complications are at higher risk of developing postoperative complications. The comprehensive complication index appeared more representative of the cumulative postoperative morbidity rather than the Clavien-Dindo classification.

Current management of non-muscle-invasive bladder cancer.

AIM: Despite standard treatment with transurethral resection (TURBT) and adjuvant therapy, many bladder cancers (BCs) recur and some progress. Based on a review of the literature, we aimed to establish the optimal current approach for the early diagnosis and management of non-muscle-invasive bladder cancer (NMIBC). METHODS: A Medline® search was conducted to identify the published literature relating to early identification and treatment of NMIBC. Particular attention was paid to factors such as quality of TURBT, importance of second TUR, substaging, and carcinoma in situ. In addition, studies on urinary markers, photodynamic diagnosis, predictive clinical and molecular factors for recurrence and progression after BCG, and best management practice were analyzed. RESULTS: Good quality of TUR and the implementation of photodynamic diagnosis in selected cases provide a more accurate diagnosis and reduce the risk of residual tumor in bladder cancer. Although insufficient evidence is available to warrant the use of new urinary molecular markers in isolation, their use in conjunction with cytology and cystoscopy can improve early diagnosis and follow-up. BCG plus maintenance for at least one year remains the standard adjuvant treatment in high-risk BC. Moreover, there is enough evidence to consider the implementation of new specific risk tables for patients treated with BCG. CONCLUSION: In high-risk patients with poor prognostic factors after TUR, early cystectomy should be considered.

[CLINICAL IMPACT OF THE SUSPENSION OF THE ERAS PROTOCOL ON PATIENTS UNDERGOING RADICAL CYSTECTOMY DURING THE COVID-19 PANDEMIC.] / IMPACTO CLÍNICO DE NO APLICAR EL PROTOCOLO ERAS EN LOS PACIENTES SOMETIDOS A CISTECTOMÍA DURANTE LA PANDEMIA COVID-19.

INTRODUCTION: During the beginning of the COVID-19 pandemic in our center, neither prehabilitation nor multimodal rehabilitation could be applied due to the excessive patient load on the health system and to reduce SARS-CoV-2 transmission. The objective of our study was to analyze the evolution, complications, and survival up to one year of patients who underwent radical cystectomy in our hospital from March 1st to May 31st, 2020 (period of the first wave COVID-19 pandemic in Spain). We also compared the results with cystectomized patients outside the pandemic period and with application of the ERAS (Enhanced Recovery After Surgery) protocol. MATERIAL AND METHODS: Single-center, retrospective cohort study of patients scheduled for radical cystectomy from March 1st,2020 to May 31st, 2020. They were matched with previously operated patients using a 1:2 propensity matching score. The matching variables were demographic data, preoperative and intraoperative clinical conditions. RESULTS: A total of 23 radical cystectomies with urinary diversion were performed in the period described. In none of the cases the prehabilitation or the follow-up of our ERAS protocol could be applied, and this was the only difference we found between the 2 groups. Although the minimally invasive approach was more frequent in the pandemic group, the difference was not statistically significant. Three patients were diagnosed with COVID-19 during their admission, presenting severe respiratory complications and high in-hospital mortality. Apart from respiratory complications secondary to SARS-CoV-2, we also found statistically significant differences in other postoperative complications. The hospital stay increased by 3 days in the pandemic group. CONCLUSIONS: Patients who underwent radical cystectomy at our center during the first wave of the COVID-19 pandemic had a higher number and severity of respiratory and non-respiratory complications. Discontinuation of the ERAS protocol was the main difference in treatment between groups.

Clinical impact of the suspension of the ERAS protocol on patients undergoing radical cystectomy during the COVID-19 pandemic.

Management of primary upper urinary tract carcinoma in situ diagnosed by ureteroscopic biopsy: Is bacillus Calmette-Guerin an alternative to nephroureterectomy?

BACKGROUND: Radical nephroureterectomy (RNU) represents the gold standard treatment for upper tract urothelial carcinoma (UTUC); however, attempts have been made to treat upper urinary tract CIS (UT-CIS) conservatively. The aim of this study was to compare the outcome of patients with primary UT-CIS treated in our center by means of RNU vs. bacillus Calmette-Guérin (BCG) instillations. METHODS: This retrospective study included patients with diagnosis of primary UT-CIS between 1990 and 2018. All patients had histological confirmation of UT-CIS in the absence of other concomitant UTUC. Histological confirmation was obtained by ureteroscopy with multiple biopsies. Patients were treated with BCG instillations, RNU or distal ureterectomy. Clinicopathological features and outcomes were compared between RNU and BCG groups. RESULTS: A total of 28 patients and 29 renal units (RUs) were included. Sixteen (57.1%) patients (17 RUs) received BCG. BCG was administered via nephrostomy tube in 4 patients, with a single-J ureteral stent in 5, and using a Double-J stent in 7. Complete response and persistence or recurrence were detected in ten (58.8%) and seven (41.2%) RUs treated with BCG, respectively. Eight (27.6%) RUs underwent RNU, and 4 (13.8%) Rus distal ureterectomy. No differences were found in recurrence-free survival (p=0.841) and cancer-specific survival (p=0.77) between the RNU and BCG groups. CONCLUSIONS: Although RNU remains the gold standard treatment for UT-CIS, our results confirm that BCG instillations are also effective. Histological confirmation of UT-CIS is mandatory before any treatment.

Indications and histology of 489 orchiectomies analyzed by patient age.

OBJECTIVE: To evaluate the indications and histology of our series of orchiectomies, analysing the results by patient's age. METHODS: We included the orchiectomies realized in our hospital between 2005 and 2020 in patients older than 18 years. We estimated demographic data, indications, histology and effectiveness of testicular ultrasound by three groups of age. RESULTS: We included 489 orchiectomies, which 364 (74%) belonged to Group A (patients between 18-50 years), 59 (12%) to Group B (50-70 years) and 66 (14%) to Group C (older than 70 years). In Group A, 284 (78%) orchiectomies were indicated due to malignancy suspect. In 91.9% cases (261) malign neoplasm was confirmed at final histology and 253 (89%) were germinal cells. Testicular ultrasound had a positive predictive value (PPV) of 90% in this group. In Group B, 34 (57%) orchiectomies were indicated because of malignancy suspect. At final histologic analysis, 25/34 (73.5%) confirmed malign neoplasm. Ultrasound had a PPV of 68%. In Group C, orchiepididymitis was the main cause of testicular removal with 30 cases (45,5%). From the 20 cases (30.3%) with suspicion of malignancy, only 6 had confirmed malign histology. Testicular ultrasound PPV for malignancy was 31%. CONCLUSION: In patients younger than 70 years the main orchiectomy's indication was suspect of malignancy and in older than 70, testicular inflammation. The germinal neoplasm was the predominant histology in younger than 70 years. In older than that, malignancy was infrequent. The positive predictive value of testicular ultrasound for malignancy decreased with patient's age. In patients older than 50 years proper image diagnosis to assess malignancy should be considered before orchiectomy is done.

Reduced- vs full-dose BCG in bladder cancer: A systematic review and meta-analysis.

OBJECTIVE: To assess the oncologic outcomes and the safety profile of a reduced-dose versus full-dose BCG regimen in patients with non-muscle-invasive bladder cancer (NMIBC). MATERIAL AND METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The PubMed, Embase, and Web of Science databases were searched in January 2022 for studies that analyzed oncological outcomes and compared between reduced- and full-dose BCG regimens. RESULTS: Seventeen studies including 3757 patients met our inclusion criteria. Patients who received reduced-dose BCG had significantly higher recurrence rates (OR 1.19; 95%CI, 1.03-1.36; p = 0.02). The risks of progression to muscle-invasive BC (OR 1.04; 95%CI, 0.83-1.32; p = 0.71), metastasis (OR 0.82; 95%CI, 0.55-1.22; p = 0.32), death from BC (OR 0.80; 95%CI, 0.57-1.14; p = 0.22), and all-cause death (OR 0.82; 95%CI, 0.53-1.27; p = 0.37) were not statistically different. When restricting the analyses to randomized controlled trials, we found similar results. In subgroup analysis, reduced dose was associated with a higher rate of BC recurrence in studies that used only an induction regimen (OR 1.70; 95%CI, 1.19-2.42; p = 0.004), but not when a maintenance regimen was used (OR 1.07; 95%CI, 0.96-1.29; p = 0.17). Regarding side effects, the reduced-dose BCG regimen was associated with fewer episodes of fever (p = 0.003), and therapy discontinuation (p = 0.03). CONCLUSION: This review found no association between BCG dose and BC progression, metastasis, and mortality. There was an association between reduced dose and BC recurrence, which was no longer significant when a maintenance regimen was used. In times of BCG shortage, reduced-dose regimens could be offered to BC patients.

Robot-assisted vs. open radical cystectomy: systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: Several randomized controlled trials (RCTs) have been launched in the last decade to examine the surgical safety and oncological efficacy of robot-assisted (RARC) vs open radical cystectomy (ORC) for patients with bladder cancer. The aim of the study was to perform a systematic review and meta-analysis of RCTs to compare the perioperative and oncological outcomes of RARC vs ORC. METHODS: A literature search was conducted through July 2022 using PubMed/Medline, Embase, and Web of Science databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. The outcomes were intraoperative, postoperative, and oncological outcomes of RARC vs ORC. RESULTS: A total of eight RCTs comprising 1,024 patients met our inclusion criteria. RARC was associated with longer operative time (mean 92.34min, 95% CI 83.83-100.84, p<0.001) and lower blood transfusion rate (Odds ratio [OR] 0.43, 95% CI 0.30-0.61, p<0.001). No differences emerged in terms of 90-day overall (p=0.28) and major (p=0.57) complications, length of stay (p=0.18), bowel recovery (p=0.67), health-related quality of life (p=0.86), disease recurrence (p=0.77) and progression (p=0.49) between the two approaches. The main limitation is represented by the low number of patients included in half of RCTs included. CONCLUSIONS: This study supports that RARC is not inferior to ORC in terms of surgical safety and oncological outcomes. The benefit of RARC in terms of lower blood transfusion rate need to be balanced with the cost related to the procedure.
