Transarterial Embolization in the Management of Intractable Haemorrhage.

INTRODUCTION: The purpose of this study was to evaluate the effectiveness and long-term results of selective transarterial iliac embolization (STIE) in patients with intractable bladder haemorrhage (IBH). METHODS: Twenty-five patients with a median age of 84 (range 65-94) years underwent STIE because of IBH between 2002 and 2020. The median follow-up time was 3 (mean 13.9) months. Patients were treated because of bleeding bladder or prostate cancer, radiation-induced haemorrhagic cystitis, and other conditions. Success was defined as technical success (feasibility to embolize bilateral hypogastric arteries or neoplastic arteries) and as clinical success (absence of further or additional therapy). RESULTS: Twenty-five patients with a median age of 84 years with a median hospital stay of 7 days were embolized at our institution. In total, 60% required additional therapy. Only 20% had minor complications, but no complication major was seen; 60% needed an additional therapy because of continuous bleeding. Our 30-day, 90-day, 6-month, and 12-month mortality rates were 28, 44, 64, and 76%, respectively. CONCLUSIONS: STIE in IBH is a safe, well-tolerated, and feasible procedure for palliating haematuria patients in poor general condition. Major complications are very rarely seen. However, patients often need additional therapy after STIE.

Bladder cancer in nonagenarians: a multicentre study of 123 patients.

OBJECTIVE: To investigate the oncological outcome of nonagenarians with bladder cancer, as a substantial rise in bladder cancer in the old-old age group in the upcoming decades is expected, due to demographic changes and the peak incidence around the age of 85 years. The paucity of data of nonagenarians prompted us to investigate the outcomes of such patients. PATIENTS AND METHODS: A retrospective, multicentre study was designed to assess patient demographics, tumour patterns, treatment strategies and outcome in patients aged ≥90 years treated at participating centres. Patients entered either as de novo or as recurrent cancer. The study period ranged from 01.01.2006 to 31.12.2016. RESULTS: A total of 123 patients with a mean (range) age of 91 (90-99) years were recruited. The American Society of Anesthesiologists Physical Status Classification (ASA-score) distribution was as follows: II, 38%; III, 50%; IV, 12%; and the male to female ratio 2.4:1. The median (range) follow-up was 8 (1-132) months. In all, 60% of patients had a de novo cancer diagnosis. Histological findings revealed: pTa 39% (n = 48), pT1 28.5% (n = 35), and ≥pT2 33% (n = 40). Overall, 67.5% patients had no recurrence, 25.2% one and 7.5% two or more. pTa tumours (n = 48) recurred in 20 patients (42%), pT1 tumours (n = 35) in 12 (34%), and ≥pT2 tumours (n = 40) in six (15%). The median overall survival (OS) was 30.0 months for patients with pTa tumours, 14.0 months for pT1 tumours, and 6.0 months for ≥pT2 tumours. The overall mortality rate of patients with pTa tumours was 40%, with pT1 tumours at 60%, and ≥pT2 tumours 75%. The ASA-score also had a strong influence on median OS after stratification by ASA-score (II, 30 months; III, 12 months; IV, 4 months). CONCLUSIONS: In nonagenarians with bladder tumours, pTa/pT1/≥pT2 stages are almost evenly distributed and two-thirds of patients had no recurrence after transurethral resection of the bladder. The mean OS was 1.3 years, and 6 months for ≥pT2 tumours. Further case-series of patients in this specific age-group are required to identify the best management of this increasing proportion of patients with bladder tumours.

Malignant mesothelioma of tunica vaginalis testis: Report of a very rare case with review of the literature.

INTRODUCTION: Mesothelioma of the tunica vaginalis testis is a extremely rare tumor and represents 0.3 to 0.5% of all malignant mesotheliomas. Exposure to asbestos often precedes illness. Because of its low incidence and nonspecific clinical presentation, it is mostly diagnosed accidentally during surgery for other reasons and the prognosis is usually poor. We present a case of a patient with a mesothelioma of tunica vaginalis testis, diagnosed secondarily during hydrocele surgery, with long-term survival after radical surgery. MATERIALS AND METHODS: a 40 years old patient was admitted to our department for routine surgery of a left hydrocele. During the operation a frozen section analysis was requested because of the unusual nodular thickening of the tunica vaginalis: the examination revealed a diffuse malignant mesothelioma with epithelioid structure and tubular-papillary proliferation. Therefore a left hemi-scrotectomy with left inguinal lymph node dissection was performed. RESULTS: The definitive histology confirmed the previous report of diffuse malignant mesothelioma with angio-invasion but normal testicle findings and negative lymph nodes. No metastases were found on the CT-scan. For the first 2 years a CT was repeated every 4 months, for other 3 years every 6 months and then yearly. Six years after surgery the patient is classified as no evidence of disease. CONCLUSIONS: malignant mesothelioma of the tunica vaginalis testis is a rare entity, often initially thought to be a hydrocele or an epididymal cyst. An aggressive approach with hemiscrotectomy with or without inguinal and retroperitoneal lymphadenectomy can reduce the risk of recurrence.

90-Day Mortality after Radical Cystectomy for Bladder Cancer: Prognostic Factors in a Multicenter Case Series.

OBJECTIVES: To identify preoperative risk factors for 90-day mortality and to validate existing nomograms in a multicenter series of patients undergoing radical cystectomy (RC). MATERIALS AND METHODS: We evaluated 90-day mortality in 475 patients following RC and urinary diversion at 2 Italian institutions and validated Aziz and Isbarn nomogram. Univariable logistic models assessed the predictive ability of operative volume, age at intervention, gender, body mass index, carcinoma in situ at transurethral resection of the bladder, American Society of Anesthesiologist (ASA) score, Charlson Comorbidity Index, clinical stage and pathological stage (TNM). RESULTS: Of the total number of patients, 387 of them (81%) were male. The median age at RC was 71.8. The most frequent ASA score was 2 (53%). Twenty-five deaths occurred within 90 days (5.3%), all among patients who had undergone RC and incontinent urinary diversion. Risk was higher in patients with advanced disease (OR 2.4); moreover, 90-day mortality odd in 70-79-year-old patients was 13 times higher than those of younger patients (<70). Predictive accuracy using Isbarn's and Aziz's nomogram were 67 and 71%, respectively. CONCLUSIONS: Our multicenter study confirmed the moderate predictive value of the Aziz nomogram. Larger studies are needed to improve on existing nomograms with the aim of enhancing preoperative counseling.

Comparative analysis of gender-related differences in symptoms and referral patterns prior to initial diagnosis of urothelial carcinoma of the bladder: a prospective cohort study.

OBJECTIVE: To analyze gender-specific differences regarding clinical symptoms, referral patterns and tumor biology prior to initial diagnosis of urothelial carcinoma of the bladder (UCB). METHODS: A consecutive series of patients with an initial diagnosis of UCB was included. All patients completed a questionnaire on demographics, clinical symptoms and referral patterns. RESULTS: In total, 68 patients (50 men, 18 women) with newly diagnosed UCB at admission for transurethral resection of bladder tumors were recruited. Dysuria was more often observed in women (55.6 vs. 38.0%, p = 0.001). Direct consultation of the urologist was conducted by 84.0% of males and 66.7% of females (p = 0.120). One third of the women saw their general practitioner and/or gynecologist once or twice (p = 0.120) before referral to the urologist. Furthermore, women were significantly more often treated for urinary tract infections than men (61.1 vs. 20.0%, p = 0.005). Cystoscopy at first presentation to the urologist was more often performed in men than women (88.0 vs. 66.7%, p = 0.068), with a more favorable tumor detection rate at first cystoscopy in men (96.0 vs. 50.0%, p < 0.001). CONCLUSIONS: Delayed referral patterns might lead to deferred diagnosis of UCB and consequently to adverse outcome. Thus, primary care physicians might consider referring patients with bladder complaints to specialized care earlier.

Comparison of complications from radical cystectomy between old-old versus oldest-old patients.

INTRODUCTION: The purpose of this study was to evaluate and compare complications after radical cystectomy in patients aged ≥75 years. MATERIALS AND METHODS: 251 patients aged 75-95 years (median 79) underwent radical cystectomy between 2000 and 2012 at four institutions. The patients were divided into two groups: ≥75-84 years of age (group 1) versus ≥85 years of age (group 2). Comorbidities, body mass index, and complications were obtained retrospectively, except at the Central Hospital of Bolzano and Weill Cornell Medical Center, which collected data prospectively. Cancer-specific survival, overall mortality, hospital stay, clinical outcome and complications were assessed. Complications were categorized using the Clavien-Dindo classification reporting system. The mean follow-up was 21 months. RESULTS: The median hospital stay was 17 (2-91) days. Perioperative Clavien-Dindo grade ≥III complications were seen in 24.1% (48/199) of group 1 patients and 19.2% (10/52) of group 2 patients (p = 0.045). 30- and 90-day mortality was 4.5 and 13.5% in group 1 and 6.5 and 32.3% in group 2, respectively. Only the 90-day mortality rate was statistically significant (p < 0.05) between the two groups. The 3-year overall survival was 40% in group 1 and 34% in group 2. The 3-year cancer-specific survival was 52% in group 1 and 50% in group 2. CONCLUSIONS: We evaluated a large series of elderly (≥75 years) patients undergoing radical cystectomy at four institutions. Comparing patients aged ≥75-84 and ≥85 years revealed no significant difference in complications, 30-day mortality, overall and cancer-specific survival rates. Only 90-day mortality rates were significantly higher in the ≥85-year-old patients.

Predictors of survival in patients with disease recurrence after radical nephroureterectomy.

OBJECTIVES: To evaluate the prognostic value of the Bajorin criteria in a multi-institutional cohort of patients with disease recurrence after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). To investigate whether clinical, pathological and/or biological factors at time of disease recurrence are also associated with cancer-specific outcomes in these patients. PATIENTS AND METHODS: We identified 242 patients with disease recurrence after RNU for UTUC from 11 centres. With regard to the Bajorin criteria, patients were categorized into three groups based on two risk factors: Karnofsky performance status <80% and the presence of visceral metastasis. Assessed variables included pathological characteristics, time to disease recurrence, age-adjusted Charlson comorbidity index (ACCI), American Society of Anesthesiologists (ASA) score, and laboratory tests at time of disease recurrence. RESULTS: Overall, 185 patients died from their disease; the median survival was 9 months. The survival rates at 1 year were 53, 33, and 39% for patients with no (n = 18), one (n = 109) and two (n = 115) risk factors, respectively, with no significant difference between the groups. In univariable analyses, higher pT-stage, tumour necrosis, non-administered salvage chemotherapy, higher ACCI score, higher ASA score, lower albumin level and higher white blood cell count were significantly associated with a shorter time to cancer-specific mortality. CONCLUSIONS: We confirmed the poor yet variable outcomes of patients with disease recurrence after RNU. While the Bajorin criteria seem to have limited prognostic value in this specific cohort, we found several other clinical variables to be associated with worse cancer-specific mortality. If validated, these factors should be taken into consideration for clinical trial design.

Perforation during TUR of bladder tumours influences the natural history of superficial bladder cancer.

OBJECTIVES: Bladder perforation is the second most common complication during transurethral resection of bladder tumours. It is unknown whether perforation affects the natural history of the tumour through cell seeding. The aim of this study was to study the impact of perforation on the oncologic outcomes of bladder carcinoma. MATERIALS AND METHODS: Between 2003 and 2007, 926 consecutive patients underwent transurethral resection of bladder tumours at our institution; 327 cases were staged ≥ pT2 and were treated immediately with cystectomy and/or multimodal therapy and therefore excluded from the study. An additional 34 cases without urothelial carcinoma were excluded. Of the remaining 565 patients with non-muscle invasive bladder cancer, 457 (80.8 %) were male and 108 (19.2 %) were female with a mean age of 69.5 years in men and 67.3 years in women. Thirty-seven patients (6.5 %) experienced bladder perforation at the time of tumour resection. This group of patients (Group 1) was compared to the remaining 528 patients (Group 2) who did not experience a bladder perforation. RESULTS: Patients with bladder wall perforation experienced a shorter disease-free survival in both univariate (p = 0.003) and multivariate analyses (p = 0.006). In addition, subsequent recurrences revealed stage progression of recurrent disease (p = 0.05) and trended to a higher number of cystectomies in the perforated group of patients (p = 0.06). Nevertheless, perforation did not appear to influence overall survival (p = 0.127) or cancer-specific survival (p = 0.141). CONCLUSION: The results indicate that bladder perforation during resection of superficial bladder tumours is burdened by a shortened disease-free survival and T-stage progression.

The Charlson comorbidity index predicts survival after disease recurrence in patients following radical cystectomy for urothelial carcinoma of the bladder.

OBJECTIVE: To identify prognostic clinical and histopathological parameters, including comorbidity indices at the time of radical cystectomy (RC), for overall survival (OS) after recurrence following RC for urothelial carcinoma of the bladder (UCB). MATERIALS AND METHODS: A retrospective multicenter study was carried out in 555 unselected consecutive patients who underwent RC with pelvic lymph node dissection for UCB from 2000 to 2010. A total of 227 patients with recurrence comprised our study group. Cox proportional hazards regression models were calculated with established variables to assess their independent influence on OS after recurrence. RESULTS: The median time from RC to recurrence and the median OS after recurrence was 10.9 and 5.4 months, respectively. Neither the time to recurrence nor the type of recurrence (systematic vs. local) was predictive of the OS. In contrast, age (hazard ratio (HR) 1.53, p = 0.011), lymph node metastasis (HR 1.56, p = 0.007), and positive surgical margins (HR 1.53, p = 0.046) significantly affected the OS after disease recurrence. In addition, the dichotomized Charlson comorbidity index (CCI; dichotomized into >2 vs. 0-2) was the only comorbidity score with an independent prediction of OS (HR 1.41, p = 0.033). We observed a significant gain in the base model's predictive accuracy, i.e. from 68.4 to 70.3% (p < 0.001), after inclusion of the dichotomized CCI. CONCLUSIONS: We present the first outcome study of comorbidity indices used as predictors of OS after disease recurrence in patients undergoing RC for UCB. The CCI at the time of RC had no significant influence on the time to recurrence but represented an independent predictor of OS after disease recurrence.

Recurrence and progression in patients with non-muscle invasive bladder cancer: prognostic models including multicolor fluorescence in situ hybridization molecular grading.

OBJECTIVE: To test the prognostic value of multicolor fluorescence in situ hybridization analyses of tumor cells in urine for prediction of the recurrence and progression of tumor in patients with intermediate risk non-muscle invasive bladder cancer. METHODS: A total of 168 patients with non-muscle invasive bladder cancer were included in the study. Fluorescence in situ hybridization was carried out on the bladder wash urine collected before resection. Tumors were classified as low molecular grading if they had a diploid chromosomal pattern or only a loss of p16 or ch3 aneuploidy, and as high molecular grading if they showed aneuploidy of ch7 or 17. Cox regression models assessed the added prognostic value of fluorescence in situ hybridization for primary tumor recurrence or progression, respectively. RESULTS: Median follow up was 67 months. A total of 57% of tumors were classified as low molecular grading. The 2- and 5-year recurrence-free survival was 68% and 49% for low molecular grading, and 47% and 30% for high molecular grading, respectively. The 2- and 5-year progression-free survival was 95% and 84% for low molecular grading, and 79% and 58% for high molecular grading tumor patients, respectively. Molecular grading (hazard ratio 1.60; P = 0.03) was associated with recurrence, when also accounting for histopathology and a patient's characteristics. Both cancer severity score (hazard ratio 1.51; P < 0.01) and molecular grading (hazard ratio 2.53; P < 0.01) independently and positively predicted progression in multivariable models. The C-index for predicting recurrence increased from 0.58 to 0.61 when molecular grading fluorescence in situ hybridization was included in the model, and from 0.68 to 0.72 when predicting progression. CONCLUSIONS: Fluorescence in situ hybridization-based molecular grading increases the accuracy of a prognostic model, predicting both recurrence and progression in patients with intermediate risk non-muscle invasive bladder cancer.

[New Sk2 guideline idiopathic posterior urethritis : Discussion of the current guideline using a case study]. / Neue Sk2-Leitlinie Urethritis posterior : Diskussion der aktuellen neuen Leitlinie anhand eines Fallbeispiels.

Posterior urethritis is diagnosed in prepubertal or pubertal boys mainly with terminal asymptomatic haematuria or postmicturition blood spotting on the meatus or in the underwear. It presents with typical changes in the bulbar urethra (hyperaemia, oedema and denuded mucosa) without laboratory or radiological findings. The pathology is self-limiting with a very good prognosis. This condition is most likely caused by dysfunctional voiding and urotherapy with biofeedback therapy offers good treatment results. Although urethrocystoscopy is the only way to confirm the diagnosis, the patient should be prevented from having a (usually unnecessary) urethrocystoscopy and the relatives should be reassured.

Prospective evaluation of the RT-PCR based urinary marker Bladder Epicheck® as a diagnostic tool in upper urinary tract tumor.

BACKGROUND: Upper-tract-urothelial-carcinoma (UTUC) represents 5-10% of all urothelial-neoplasms with increasing incidence in the last decades. Current standard tools for diagnosis of UTUC include cytology, computed tomography (CT) urography and ureterorenoscopy (URS). The aim of this study was to evaluate the impact of Bladder Epicheck® Test as diagnostic tool for UTUC diagnosis and recurrence. METHODS: Overall, 136 urine samples, selective collected from upper-urinary-tract before URS for suspicion of UTUC were analyzed with cytology and Bladder Epicheck® Test. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of both markers were calculated and compared to URS and/or histology as reference. RESULTS: UTUC was detected in 40 cases (33.3%), among them 30 were classified as low-grade (LG) and 10 as high-grade (HG). Overall sensitivity of Bladder Epicheck® for UTUC detection was 65% compared to 42.5% for cytology, increasing to 100% for Bladder Epicheck® and 90% for cytology if considering only HG tumors. Overall specificity of Bladder Epicheck® was 81.2% and of cytology 93.7%. PPV and NPV were 63.4% and 82.2% for Bladder Epicheck® and 77.2% and 76.5% for cytology. Considering an EpiScore cut-off >75, instead of 60, specificity of Bladder Epicheck® improves to 89% and PPV to 74.2%. Limitations include the use of a marker validated only for bladder-cancer and the relatively small number of cases. CONCLUSIONS: Due to its high sensitivity for HG tumors, the Bladder Epicheck® Test can be used in diagnosis and treatment decision-making of UTUC. Furthermore, it could be very useful in follow-up of UTUC, after endoscopic treatment to postpone or avoid unnecessary endoscopic exploration. Even if further studies are needed to validate these findings, Bladder Epicheck® could be a promising clinical tool for detection of UTUC.

Obesity is associated with worse outcomes in patients with T1 high grade urothelial carcinoma of the bladder.

PURPOSE: To our knowledge the impact of body mass index on oncologic outcomes in nonmuscle invasive bladder cancer has not been evaluated. We hypothesized that higher body mass index is associated with worse outcomes in patients with clinical primary T1 high grade urothelial carcinoma of the bladder. MATERIALS AND METHODS: We retrospectively analyzed data from 892 patients with primary nonmuscle invasive bladder cancer from 7 centers. Patients were treated with transurethral resection of the bladder with or without intravesical therapy. Body mass index was analyzed as a continuous and a categorical variable (nonobese-body mass index less than 30 kg/m(2) vs obese-body mass index 30 kg/m(2) or greater). Disease progression was defined as the development of T2 or higher tumor stage. RESULTS: Median followup was 42.8 months (IQR 56). Of the patients 44.3% were obese and median body mass index was 29.2 kg/m(2) (IQR 8). On univariable analyses higher body mass index and age were associated with an increased risk of disease recurrence, progression, cancer specific mortality and any cause mortality (all p ≤ 0.001). On multivariable analyses that adjusted for the effects of gender, concomitant carcinoma in situ, tumor size, number of tumors and intravesical therapy, higher body mass index and age remained independent predictors of disease recurrence, progression, cancer specific mortality and any cause mortality (all p <0.05). This study was limited by its design (ie lack of data on repeat transurethral resection of the bladder and intravesical therapy protocol). CONCLUSIONS: Patients diagnosed with clinical T1 high grade urothelial carcinoma of the bladder who are obese have worse cancer specific outcomes compared to their nonobese counterparts. Further work is needed to improve our understanding of clinical T1 high grade outcomes in the growing population of obese patients.

Prediction of true nodal status in patients with pathological lymph node negative upper tract urothelial carcinoma at radical nephroureterectomy.

PURPOSE: The role of lymph node dissection is still controversial in patients treated with radical nephroureterectomy for upper tract urothelial cancer. We developed a pathological nodal staging model that allows quantification of the likelihood that a patient with pathologically node negative disease has, indeed, no lymph node metastasis. MATERIALS AND METHODS: We analyzed data on 814 patients treated with radical nephroureterectomy and lymph node dissection, and estimated the sensitivity of pathological nodal staging using a ß-binomial model. We developed a pathological nodal staging score that represents the probability that a case is correctly staged as node negative. RESULTS: A median of 5 lymph nodes (range 1 to 46) was removed and 593 patients (73%) had pN0 disease. The probability of missing lymph node metastasis decreased as the number of nodes examined increased. If only a single node was examined, 44% of patients would have been misclassified as having pN0 disease while harboring lymph node metastasis. Even when 5 nodes were examined, 12% of patients would have been misclassified. The proportion of those with a positive node increased with advancing pathological T stage and lymphovascular invasion. Patients with pT0-Ta-Tis-T1/lymphovascular invasion had more than a 95% chance of correct pathological nodal staging with 2 examined nodes. However, if a patient had pT3-T4 and positive lymphovascular invasion, even 20 examined lymph nodes did not attain 95% accuracy. CONCLUSIONS: Lymph node dissection provides more accurate staging and prediction of survival. The number of examined nodes needed for adequate staging depends on pT stage and lymphovascular invasion. We developed a tool to estimate the likelihood of false-negative lymph node metastasis, which could help refine clinical decision making regarding the administration of adjuvant chemotherapy.

Do differences in clinical symptoms and referral patterns contribute to the gender gap in bladder cancer?

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Urothelial carcinoma of the bladder (UCB) is more prevalent in men than women; however, in women the tumour stage is generally more advanced at the time of the diagnosis and the prognosis is worse. Possible explanations include anatomical, genetic and socio-economic factors. The study shows that clinical symptoms before the first-time diagnosis of UCB did not differ between the sexes, while primary care and referral patterns did. Women were more likely to receive symptomatic treatment or therapies for alleged UTIs without further investigation or referral to urological evaluation. The study highlights the fact that there may be a diagnostic delay in women which could contribute to the gender-dependent disparities in stage distribution and prognosis of UCB. OBJECTIVE: To evaluate gender-dependent disparities regarding clinical symptoms, referral patterns or treatments before diagnosis of urothelial carcinoma of the bladder (UCB). PATIENTS AND METHODS: A consecutive series of patients with newly diagnosed UCB completed a questionnaire at the time of admission for elective transurethral resection of a bladder tumour (TURBT). The questionnaire surveyed the presence of haematuria, dysuria, urgency and bladder pain as well as the number of consultations and treatments before urological evaluation. Tumour characteristics, clinical symptoms, treatments and referrals were compared between men and women in the patient series. RESULTS: In men (n = 130) the distribution of tumour stages was pTa 62.3%, pT1 23.1% and pT ≥ 2 12.3%. The respective percentages in women (n = 38) were pTa 57.9%, pT1 23.7% and pT ≥ 2 18.4% (P > 0.05). The prevalence of clinical symptoms in men vs women was as follows: gross haematuria 65 vs 68%, dysuria 32 vs 44%, urgency 61 vs 47%, and nocturia 57 vs 66%, respectively (P > 0.05). A total of 78% of men vs 55% of women directly consulted a urologist (P < 0.05). Symptomatic treatment for voiding disorders/pain was given without further evaluation to 19% of men vs 47% of women 1 year before the diagnosis of UCB (P < 0.05). A total of 3.8% of men vs 15.8% of women received three or more treatments for urinary tract infections (UTIs) within the same time period (P < 0.05). CONCLUSIONS: In the present study there were no gender-related differences in clinical symptoms of UCB, but women were more likely to be treated for voiding complaints or alleged UTIs without further evaluation or referral to urology than men. Gender-dependent disparities in referral patterns exist and might delay definitive diagnosis of UCB in women.

Impact of renal function on eligibility for chemotherapy and survival in patients who have undergone radical nephro-ureterectomy.

UNLABELLED: What's known on the subject? and what does the study add?: Radical nephroureterectomy (RNU), the standard of care treatment for high-risk urothelial carcinoma of the upper tract (UTUC), results in loss of a renal unit. Loss of renal function decreases eligibility for systemic chemotherapies and results in decreased overall survival in various malignancies. The study shows that only a small proportion of patients had a preoperative renal function that would allow cisplatin-based chemotherapy. Moreover, eGFR significantly decreased after RNU, thereby lowering the rate of cisplatin eligibility to only 16 and 52% of patients based on the thresholds of 60 and 45 mL/min/1.73 m(2) , respectively. Taken together with the rest of the literature, the findings of the study support the use of cisplatin-based chemotherapy, when indicated, in the neoadjuvant rather than adjuvant setting. OBJECTIVE: To report (i) the estimated glomerular filtration rate (eGFR) changes in patients undergoing radical nephro-ureterectomy (RNU) for upper tract urothelial carcinoma (UTUC); (ii) the rate of change in eGFR in patients eligible for cisplatin-based chemotherapy; and (iii) the association of preoperative, postoperative and rate of change of renal function variables with survival outcomes. PATIENT AND METHODS: We performed a retrospective analysis of 666 patients treated with RNU for UTUC at seven international institutions from 1994 to 2007. The eGFR was calculated at baseline and at 3-6 months (Modification of Diet in Renal Disease formula (MDRD) and Chronic Kidney Disease Epidemiology Collaboration formula (CKD-EP) equations). RESULTS: The median (interquartile range) eGFR decreased by 18.2 (8-12)% after RNU. A total of 37% of patients had a preoperative eGFR ≥ 60 mL/min/1.73 m(2) , which decreased to 16% after RNU (P < 0.001); 72% of patients had a preoperative eGFR ≥ 45 mL/min/1.73 m(2) , which decreased to 52% after RNU (P < 0.001). The distributions were similar when analyses were restricted to patients with locally advanced disease (pT3-pT4) and/or lymph node metastasis. Patients older than the median age of 70 years were more likely to have a decrease in eGFR after RNU (P < 0.001). None of the renal function variables was associated with clinical outcomes such as disease recurrence, cancer-specific and overall mortality; however, when analyses were restricted to patients who had no adjuvant chemotherapy and did not experience disease recurrence (n = 431), a preoperative eGFR ≥ 60 mL/min/1.73 m(2) (P = 0.03) and a postoperative eGFR ≥ 45 mL/min/1.73 m(2) (P = 0.04) were associated with better overall survival in univariable analyses. CONCLUSIONS: In patients who had UTUC, eGFR was low and furthermore, it significantly decreased after RNU. Renal function did not affect cancer-specific outcomes after RNU.

Outcomes and prognostic factors in patients with a single lymph node metastasis at time of radical cystectomy.

OBJECTIVES: To identify clinicopathological factors that predict outcomes in patients with a single lymph node (LN) metastasis (pN1) treated with radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). LN metastasis is an established predictor of clinical outcomes in patients. While most patients with large LN burden experience disease recurrence, lymphadenectomy can be curative in patients with pN1 disease. PATIENTS AND METHODS: We analysed 381 patients with pN1 UCB from a multi-institutional cohort of 4335 patients with UCB treated with RC and lymphadenectomy without preoperative chemo- or radiotherapy. Subgroup analyses were performed for patients with ≥9 LNs removed and according to adjuvant chemotherapy administration (n = 215). RESULTS: The median (interquartile range, IQR) LN number was 15 (19) and the median (IQR) LN density was 6.7 (7.5)%. Within a median follow-up of 41 months, the mean (+/- SD) 2- and 5-year cancer-specific survival (CSS) rates were 55 (3)% and 46 (3)%, respectively. On multivariable analysis that adjusted for the effects of standard clinicopathological features, female gender (hazard ratio [HR] 1.48, P = 0.023), higher tumour stage (HR 1.68, P = 0.007), positive soft tissue surgical margin (STSM; HR 2.06, P = 0.004), higher LN density (HR 2.99, P = 0.025) and absence of adjuvant chemotherapy (HR 0.70, P = 0.026) were independently associated with CSS. In subgroup analyses of patients with ≥9 LNs removed, tumour stage and STSM status remained independent predictors for CSS (P = 0.009 and P < 0.001, respectively). CONCLUSIONS: About half of the patients with pN1 UCB died from UCB within 5 years of RC. Pathological stage and STSM status are strong predictors for outcomes. Accurate prediction of the individual risk of CSS may help risk stratifying pN1 UCB in order to help improve clinical-decision making. Patients with pN1 UCB presenting with additional unfavourable risk factors need a closer follow-up scheduling and might receive adjuvant therapy.

Female gender is associated with higher risk of disease recurrence in patients with primary T1 high-grade urothelial carcinoma of the bladder.

PURPOSE: An increasing body of evidence suggests gender differences in the presentation and prognosis of bladder cancer. We aimed to assess the impact of gender on outcomes in patients with primary T1 high-grade (HG) urothelial carcinoma of the bladder (UCB). METHODS: We retrospectively analysed the data from 916 patients with primary T1HG UCB from 7 tertiary care centres. Patients were treated with transurethral resection of the bladder with or without intravesical instillation therapy (IVT). Univariable and multivariable Cox regression analyses assessed the effect of gender on outcomes. RESULTS: Within a median follow-up of 42.8 months, 365 (39.8 %) patients experienced disease recurrence, 104 (11.4 %) progression, 59 (6.4 %) cancer-specific mortality and 190 (20.7 %) mortality of any cause. Overall, 634 (69.2 %) patients received IVT of which 234 (25.5 %) received BCG therapy. Female gender (n = 190, 20.7 %) was associated with higher risk of disease recurrence (HR:1.359;1.071-1.724, p = 0.012) in all patients and in a subgroup of patients treated with BCG therapy (HR:1.717;1.101-2.677, p = 0.017). There was no difference between genders with regard to disease progression, cancer-specific mortality and any-cause mortality. In multivariable analyses that adjusted for the effects of concomitant carcinoma in situ (CIS), tumour size, number of tumours, and IVT, gender remained an independent predictor for disease recurrence (p = 0.026) when analysed in all patients, but not in the subgroup of BCG treated patients (p = 0.093). CONCLUSIONS: In patients with T1HG UCB, female gender is associated with higher risk of disease recurrence, but not with disease progression. This gender disparity may be due to differences in care and/or biology of UCB.

Comparison of radical cystectomy with conservative treatment in geriatric (≥80) patients with muscle-invasive bladder cancer.

INTRODUCTION: The aim of this study was to compare overall survival in elderly patients (≥ 80 years) with muscle-invasive bladder cancer (MIBC) undergoing either radical cystectomy (RC) or conservative treatment. MATERIAL AND METHODS: We performed a retrospective, comparative analysis of overall- and cancer-specific survival in octagenarians with MIBC (≥ pT2) submitted to RC or conservative treatment. Uni- and multivariable Cox regression analysis were performed to assess predictors of overall survival. Cumulative hospital stay was also analyzed for all patients. RESULTS: The RC-group consisted of 33 patients with a mean age of 82.3 years (IQR 80.4-85.4 years) and the bladder preservation a cohort of 35 patients aged 83.8 years (IQR 81.8-88.2 years). No difference was detectable for overall survival (15.9 months versus 9.5 months; p = 0.18) and cancer-specific survival (23.5 months versus 19.5 months p = 0.71) or 90-day mortality (6.1% versus 14.3%; p = 0.43) between the two groups. Patients who received conservative treatment had a shorter cumulative length of hospital stay (p = 0.001). Age at the time of transurethral resection of the bladder (TUR-B) was an independent predictor of the overall survival (p = 0.004). CONCLUSIONS: In this retrospective study, no clear survival benefit was observed for patients ≥80 years submitted either to radical cystectomy or conservative treatment. There was however a trend favoring radical cystectomy but this did not approach statistical significance. Octagenarians that underwent RC however spent more of their remaining lifetime in the hospital than those treated conservatively.

[Sigmoid colon conduit volvulus: an extremely rare complication of a sigmoid colon conduit]. / Sigmakonduit Volvulus: eine extrem seltene Komplikation eines Sigmakonduit.

We report the case of an 84-year-old man with the rare diagnosis of a volvulus of an incontinent sigmoid colon urinary conduit after radical cystoprostatectomy due to urinary bladder cancer. To the best of our knowledge, this is the first case in literature of a volvulus of a sigmoid colon conduit.
