ABSTRACT
Human mouse double minute 2 (Mdm2) plays an essential role in the regulation of the tumor suppressor p53. The G/G variant of SNP309 was shown to increase Mdm2 mRNA/protein expression and to be associated with an increased risk and earlier onset of different cancers in Asian populations. However, the frequency and impact of these G/G variants have not been studied in Caucasian renal cell carcinoma (RCC) patients. Therefore, we analyzed an unselected German cohort of 197 consecutive RCC patients and detected the G/G variant in 18 (9.1%) patients, the G/T variant in 116 (58.9%) patients and the T/T variant in 63 (32.0%) patients. Studying the association between age at tumor onset and SNP309 genotypes, no correlation was detected in the entire RCC cohort or among the male RCC patients. However, the female G/G patients (median age 59.5 years) were diagnosed 13.5 years earlier than the T/T females (median age 73 years). When separating all females into two groups at their median age (68 years), 7 and 1 patients with the G/G variant and 9 and 13 patients with the T/T variant were noted in these age groups (P=0.024). To study the age dependency of tumor onset further, a second, age-selected cohort of 205 RCC patients was investigated, which comprised especially young and old patients. Interestingly, the G/G type occurred more often at lower tumor stages and tumor grades compared with higher stages (P=0.039 and 0.004, respectively). In females, the percentage of the G/G variant was only slightly higher in the younger age group, whereas in males, the percentage of the G/G variant was remarkably higher in the younger age group (19.4% vs 8.0%). In summary, female Caucasian RCC patients with the MDM2 SNP309 G/G genotype showed significantly earlier tumor onset than patients with the wild-type T/T genotype.
ABSTRACT
BACKGROUND: Urothelial carcinoma of the bladder (UBC) at stage pT1 is a heterogenous disease. Established criteria for prognosis prediction are not suitable for every patient. Choosing the right therapeutic strategy for the individual patient thus remains a challenge. The aim of the present study was to identify clinical parameters regarding cancer-specific survival (CSS) in patients with pT1 UBC. MATERIALS AND METHODS: A retrospective analysis of clinical parameters of all patients with a pT1 UBC between 1989 and 2012 from a single centre was performed. Treatment consisted of transurethral resection, second resection followed by initially bladder sparing treatment. Anamnestic data, histopathological reports and clinical course were assessed with CSS being defined as primary endpoint. Kaplan-Meier analysis, uni- and multivariate analysis were performed using SPSS (Version 22, IBM). RESULTS: 378 patients (78% male, median age 72 years) were included, median follow-up was 35 months. Pathological stage pT1G3 (66 vs. 91%, p<0.001), lack of instillation therapy (66 vs. 83%, p<0.001), presence of a second malignoma (41 vs. 77%, p=0,004), diagnosis after 2000 (75 vs. 76%, p=0,018) and tumour progress (42 vs. 85%, p<0.001) were associated with a worse CSS in univariate and Kaplan-Meier analysis. Multivariate analysis revealed the presence of a second malignoma (HR 2.267; CI 95% 1.143-4.497, p=0.019), pathological stage pT1G3 at initial diagnosis (HR 4.567; CI 95% 2.040-10.22, p<0.001) and tumour progress (HR 3.742; CI 95% 1.544-9.069, p=0.003) as independent negative predictors of CSS. Instillation therapy was a prognostic factor for improved CSS (HR 0.368; CI 95% 0.212-0.638, p<0.001). CONCLUSION: The present study identified the presence of a second malignoma, pathological stage pT1G3 and tumour progress as negative predictive factors for CSS. Maintenance instillation therapy after reresection was associated with an improved CSS.

PURPOSE: Rectourinary fistula (RUF) is an uncommon but devastating condition that usually occurs as a complication of surgical treatment or radiotherapy of prostate cancer. Although operative fistula repair remains the most successful treatment, there still is no consensus concerning the management of RUF. We present first experiences and transanal surgical technique using biological mesh for fistula repair after urological intervention. MATERIAL AND METHODS: From January 2009 to December 2013, four cases of RUF were reported at our university hospital. Fistula occurred after extraperitoneal laparoscopic radical prostatectomy, open radical prostatectomy, and high-intensity focused ultrasound, respectively. All patients were initially treated with transanal Cook Biodesign™ mesh, whereas two patients received reoperation with rectal mucosa advancement flap and gracilis muscle flap interposition, respectively. Mean follow-up was 36 months (range 9-62). RESULTS: Fistula diameters ranged from 0.6 to 3.0 cm and were located 5 to 6 cm of anocutaneous line. The time from diagnosis to fistula repair was 3 to 7 weeks. The median operative time for Cook Biodesing™ mesh procedure was 79 min (IQR 60, 98). The initial success rate for biological mesh was 50 % (2/4 patients). Larger fistulae were minimalized successfully and finally closed with reoperation mentioned above. No deterioration of continence was documented. CONCLUSIONS: Management of rectourinary fistula is still challenging. Using biomaterials for fistula closure seems to be a promising and minimally invasive transanal technique in future. Further analysis including more patients is needed to clarify its exact role in comparison to traditional surgical techniques.

PURPOSE: Radical cystectomy (RC) can be associated with significant blood loss, whereas many patients are presenting with anemia preoperatively. To date, there is a lack of data addressing the impact of preoperative anemia (PA) on survival of patients undergoing RC for urothelial carcinoma of the bladder (UCB). METHODS: This retrospective multicenter study includes 684 patients with UCB undergoing RC with pelvic lymph node dissection. The median follow-up was 50 (IQR 29,78) months. Anemia was defined in line with the WHO classification (hemoglobin (Hb): male ≤13 g/dL, female ≤12 g/dL) and based on contemporary gender- and age-adjusted classification (Hb: white male aged <60 years: ≤13.7 g/dL; ≥60 years: ≤13.2 g/dL; white female of all ages ≤12.2 g/dL). Univariable and multivariable Cox regression analyses were used to assess the effects of PA on oncological outcomes. RESULTS: A total of 269 (39.3 %) and 302 (44.2 %) patients were anemic according to the WHO classification versus contemporary classification. Age, increased ECOG performance status, advanced tumor stages, lymph node metastasis, positive surgical margin and anemia were associated with disease recurrence (DR), cancer-specific mortality (CSM) and all-cause mortality (ACM). In multivariable analysis, anemia was an independent predictor of DR, CSM and ACM (WHO and/or contemporary classification). Blood transfusion was significantly associated with ACM in both classifications of anemia. CONCLUSIONS: PA is significantly associated with worse oncological outcome in patients undergoing RC. Based on the additional unfavorable influence of blood transfusion, this emphasizes the importance of early diagnosis and correction of anemia and implementation of alternative methods of blood volume management.

Condyloma acuminata are the most frequent cause of infections in the anal genital area. They are caused by the human papilloma virus (HPV). Risk factors are early onset of sexual activity, multiple sexual partners, a history of sexually transmitted disease, and immunosuppression. The urethra is afflicted in only 20% of cases; of these, 80% of the warts are at the meatus and 20% in the proximal urethra. This article reports on two cases with condyloma acuminata affection of the total urethra. The current diagnostic, different treatment modalities, and prophylaxis are reviewed.

PURPOSE: Radical cystectomy (RC) can be associated with significant blood loss. Allogenic blood transfusion (ABT) may alter disease outcome because of a theoretical immunomodulatory effect. We evaluated the effects of ABT on overall survival (OS) and progression-free survival (PFS) of patients undergoing RC for urothelial carcinoma of the bladder (UCB). MATERIALS AND METHODS: This is a retrospective single-center study of 350 consecutive patients of a university health center with a median follow-up of 70.1 month. All patients underwent RC and pelvic lymph node dissection. The effect of ABT on OS and PFS was analyzed using univariable and multivariable Cox proportional hazards models. RESULTS: The overall ABT rate was 63 % (n = 219), with intraoperative blood transfusion and postoperative blood transfusion being performed in 183 patients (52 %) and 99 patients (28 %), respectively. Preoperative anemia was detected in 156 patients (45 %) with median estimated blood loss of 800 ml (IQR: 500-1,200). ABT was associated with significant decrease of OS and PFS in multivariable analyses (p < 0.001), whereas patients' prognosis worsened the more packed red blood cells (PRBC) were transfused (p < 0.001). The study is limited in part due to its retrospective design. CONCLUSIONS: We found that ABT and the number of PRBC transfused are associated with poor prognosis for UCB patients undergoing RC, whereas preoperative anemia had no influence on survival. This emphasizes the importance of surgeon's awareness for a strict indication for ABT. A prospective study will be necessary to evaluate the independent risks associated with ABT during surgical treatments.

PURPOSE: Radical cystectomy (RC) and pelvic lymph node dissection (LND) are standard treatments for muscle-invasive urothelial carcinoma of the bladder. Lymph node staging is a prerequisite for clinical decision-making regarding adjuvant chemotherapy and follow-up regimens. Recently, the clinical and pathological nodal staging scores (cNSS and pNSS) were developed. Prior to RC, cNSS determines the minimum number of lymph nodes required to be dissected; pNSS quantifies the accuracy of negative nodal staging based on pT stage and dissected LNs. cNSS and pNSS have not been externally validated, and their relevance for prediction of cancer-specific mortality (CSM) has not been assessed. METHODS: In this retrospective study of 2,483 RC patients from eight German centers, we externally validated cNSS and pNSS and determined their prediction of CSM. All patients underwent RC and LND. Median follow-up was 44 months. cNSS and pNSS sensitivities were evaluated using the original beta-binominal models. Adjusted proportional hazards models were calculated for pN0 patients to assess the predictive value of cNSS and pNSS for CSM. RESULTS: cNSS and pNSS both pass external validation. Adjusted for other clinical parameters, cNSS can predict outcome after RC. pNSS has no independent impact on prediction of CSM. The retrospective design is the major limitation of the study. CONCLUSIONS: In the present external validation, we confirm the validity of both cNSS and pNSS. cNSS is an independent predictor of CSM, thus rendering it useful as a tool for planning the extent of LND.

BACKGROUND: High-risk non-muscle-invasive bladder cancer (NMIBC) progressing to muscle-invasive bladder cancer (MIBC) is associated with adverse tumour biology. It is unclear, however, whether outcome of NMIBC progressing to MIBC is adverse compared to primary MIBC and whether NMIBC of higher risk of progression to MIBC is adverse compared to NMIBC of lower risk. OBJECTIVE: Our objective was to assess cancer-specific survival (CSS) following radical cystectomy (RC) for primary MIBC and for NMIBC progressing to MIBC in dependence of EORTC risk score. MATERIALS AND METHODS: Clinical and histopathological characteristics and CSS of 150 patients were assessed. Secondary MIBCs were stratified by EORTC risk score at the last transurethral resection of bladder tumour for NMIBC. RESULTS: CSS did not differ significantly between primary and secondary MIBC (p = 0.521). Secondary MIBC with high EORTC score had significantly shorter CSS compared to secondary MIBC with intermediate EORTC score (p = 0.029). In multivariable analysis, pathological tumour stage (HR = 3.77; p = 0.020) and lymph node stage (HR = 2.34; p = 0.022) were significantly correlated with CSS. CONCLUSION: While the outcome of secondary MIBC is not generally adverse compared to primary MIBC, the EORTC risk score not only reflects high risk of progression of NMIBC to MIBC, but also worse outcome following RC for secondary MIBC. Timely RC should thus be debated in high-risk NMIBC.

Chronic lymphocytic leukemia (CLL) with 17p deletion or mutations of the TP53 gene has a very poor outcome. Optimal treatment of these patients remains a major clinical challenge, and disagreement on the optimal treatment approach exists. Conventional chemo-immunotherapy with rituximab in combination with purine analogues yields lower response-rates and less satisfactory results than for CLL patients with intact p53. Allogeneic stem cell transplantation may allow long-term remissions in this challenging group of patients. In this review, we will discuss current treatment options as well as experimental approaches in clinical trials for CLL patients with deleted or mutated TP53. Particular emphasis will be placed on novel agents with the potential to change clinical practice and future perspectives for the management of these "highest risk" patients.

Incidental prostate cancer is often found in cystoprostatectomy specimens. The presence of a clinically significant tumour has an impact on follow-up strategies. In prostatectomy specimen for prostate cancer, whole-mount sections improve diagnostic accuracy. The present study compares detection of incidental prostate cancer in complete to routine processing. We included 295 consecutive patients who underwent radical cystoprostatectomy. Between 01/1995 and 12/2003 (period I), specimens of 129 patients were partially processed, whereas between 01/2004 and 03/2009 (period II), specimens of 166 patients were completely processed. Incidental prostate cancer was detected overall in 91 (30.8 %) patients. Prostate cancer was detected in 24 (18.6 %) patients in period 1 and in 67 (40.4 %) patients in period 2 (p < 0.001). Potentially clinically significant prostate cancer was detected in 12 (9.2 %) and 29 (17.5 %) patients, respectively (p = 0.044). Complete embedding and processing of cystoprostatectomy specimen yield significantly more potentially clinically relevant prostate cancers. The present data suggest that notably in younger men the specimens should be completely processed.

INTRODUCTION: Lower urinary tract symptoms (LUTS) are a common and multiform micturition disorder of various possible origins. Several second-line techniques are available in the event of first-line medicinal treatment failure. These include the intravesical injection of Botulinum toxin, bladder augmentation and sacral neuromodulation (SNM). This study presents current data and results from a prospective study of patients with LUTS of various aetiologies. MATERIAL AND METHODS: Clinical success was investigated for all patients who underwent SNM for LUTS with or without urge incontinence caused by chronic pelvic pain syndrome, multiple sclerosis and idiopathic disease between May 2007 and December 2010. The preoperatively determined symptoms were compared with current follow-up data. Median follow-up time was 11âmonths (1 - 43). RESULTS: A total of 47âpatients were indicated for SNM over the investigated period. 80.9 % were female, median patient age was 67âyears (19 - 84). The testing phase was successful in 38âcases (80.9 %) with 9 electrodes being explanted (19.1 %). In the case of idiopathic LUTS we could show a statistically significant increase of micturition volume and reduction of incontinence pad use. There was no statistically significant improvement of any micturition parameter for patients with multiple sclerosis, patients with chronic pelvic pain syndrome showed a statistically significant reduction of micturition frequency and a subjective improvement of symptoms in 75 %. CONCLUSIONS: In the selected patient groups SNM is a promising and, in experienced hands, a low-complication second-line therapy for the treatment of LUTS of idiopathic aetiology. However, the general recommendation of SNM for multiple sclerosis and chronic pelvic pain syndrome patients cannot be given on the basis of our results. Further prospective, randomised multicentre studies are need to further refine the indications for SNM in LUTS of neurogenic and non-neurogenic origins.

To develop a reliable immunohistochemical marker panel differentiating between the three most common renal cell carcinoma (RCC) subtypes without inclusion of histomorphologic criteria we investigated protein expression of vimentin, glutathione S-transferase alpha (GST-α), CD10, CD117 (C-KIT), carbonic anhydrase 2 (CAII), parvalbumin, alpha-methyl-CoA-racemase (AMACR), and cytokeratin-19 (CK 19) in 65 age and stage matched trios of clear cell carcinoma, papillary renal carcinoma and chromophobe renal carcinoma using tissue microarrays. All markers displayed significant differential expression among the subtypes (p < 0.001) except CAII (p = 0.192). According to positive (LR+) and negative (LR-) likelihood ratio, six markers (CD10, GST-α, AMACR, CK19, C-KIT and arvalbumin) demonstrated acceptable or good values to detect certain subtypes of RCC, but failed in terms of ruling out the respective subtypes. Based on the individual performance of these six markers, we combined them and reviewed each single case: LR+ for detection of clear cell RCC considerably increased by application of the six marker panel, but did not exceed 10. LR- was still >0.1; in case of papillary RCC LR+ rose beyond 10, but LR- remained >0.1. LR+ for recognition of chromophobe RCC rose far beyond 10, but LR- remained >0.1. Thus, the panel can reliably recognize two main RCC subtypes without inclusion of histomorphologic features. Further improvement is needed for consistent detection of clear cell RCC and for dependably ruling out all three main subtypes as well as identification of rare variants and benign lesions like oncocytoma.

BACKGROUND: Somatic point mutations in the fibroblast growth factor receptor 3 (FGFR3) gene have been identified in certain types of urological cancers, especially urothelial carcinoma of the bladder and the renal pelvis, and could be correlated with a favourable outcome. However, comprehensive data on the FGFR3 mutation status in renal cell carcinoma (RCC) are still missing. METHODS: In order to investigate a possible role for FGFR3 mutations in renal cell carcinogenesis, we performed a sequence-based mutational analysis of FGFR3 in 238 primary RCC. The cohort obtained the common RCC subtypes including 101 clear cell, 50 papillary and 68 chromophobe RCC specimens. The analysed regions encompassed all FGFR3 point mutations previously described in epithelial tumours and other noncutaneous epithelial malignancies. RESULTS: No mutations were detected in any renal tumour type examined, and all cases showed wild-type sequence. CONCLUSION: Our results argue against an involvement of mutational activation of FGFR3 in the development of RCC. A recently described cystic renal dysplasia in a patient with thanatophoric dysplasia type 1 due to a germ line FGFR3 mutation might portend to an involvement of mutational FGFR3 activation in renal cyst formation, but this speculation needs further evaluation.

INTRODUCTION: Transurethral resection of the bladder (TURB) is one of the most common surgical treatments in urology. We examined the TURBs that had been carried out during one year for suspected bladder cancer (first findings and recurrence) and then analysed the further clinical courses of these patients within the first twelve months after TURB. MATERIALS AND METHODS: We recorded retrospectively the course of 160 patients in whom altogether 210 elective TURBs had been performed in our clinic between April 2007 and March 2008 (observation period). In addition, the patients' further clinical course within the first twelve months after TURB was recorded (follow-up period). All initial and recurrence TURB were carried out with photodynamic diagnosis; the histological evaluation was performed at a university centre. RESULTS: 71 % of the 118 initial resections performed during the observation period showed urothelial cell carcinoma of the bladder - pTa (61 %), pT1 (20 %), pT2-4 (17 %), Cis (2 %) while 60 re-TURBs in the whole period detected 17 % residual tumours. According to the guidelines, 18 patients (14 %) received instillation therapy with mitomycin C, 32 patients (25 %) with Bacillus Calmette-Guérin (BCG). Cystectomies were performed on 23 patients (18 %). 18 TURBs after suspected recurrence in the follow-up period confirmed recurrence in 28 %, which represents a recurrence rate of 4 %. In the same period 5 patients (4 %) developed distant metastases, two patients (2 %) died. Two patients (7 %) with initially benign findings developed bladder cancer in the follow-up period. CONCLUSION: We present an analysis of TURBs performed at a university centre. When bladder cancer is diagnosed in 7 % within one year after urocystitis has been detected in the initial TURB findings, regular follow-up examination of these patients, especially with certain risk profiles, has to be discussed.

PURPOSE: Renal cell carcinoma is the third most frequent urogenital malignancy. The increased incidence in the past few years can be attributed in particular to increased incidental findings since the introduction of routine ultrasound and radiological imaging. In the current contribution we analyse in a long-term approach the actual impact of these advances on indications for surgical management. MATERIAL AND METHODS: From January 1992 until December 2007, 1,113 renal cell carcinoma patients underwent a total of 1,129 surgical interventions in our department. Retrospectively, we collected the clinical and histopathological data of these patients, comparing them in terms of the entire study period and the four 4-year time spans 1992-1995, 1996-1999, 2000-2003 and 2004-2007. RESULTS: 59 % of the patients were male, the median age being 64 years [range: 26-91 years]. In the study period, the number of patients

PURPOSE: Urothelial carcinoma with plasmacytoid morphology is a rare and only recently described histological variant. To date only 22 cases have been published. We present clinical and histopathological features of 5 cases of plasmacytoid urothelial carcinoma at our institutions. MATERIALS AND METHODS: From a consecutive series of 130 muscle invasive urothelial carcinoma cases 3 of plasmacytoid urothelial carcinoma (2.3%) were identified. Two additional plasmacytoid urothelial carcinoma cases, including 1 that was noninvasive, were also studied. Data were collected from clinical charts, histological review and followup. RESULTS: Four patients had a muscle invasive tumor at first presentation. The nonmuscle invasive plasmacytoid urothelial carcinoma represents the second published case in the literature. Conventionally differentiated urothelial carcinoma was focally present in every case. Plasmacytoid urothelial carcinoma cells were dyshesive and showed abundant eosinophilic cytoplasm, leading to a plasmacytoid appearance. Positive staining for epithelial markers confirmed the epithelial nature of the tumor. All tumors showed negative E-cadherin expression. Adjuvant or neoadjuvant chemotherapy seemed to have a beneficial effect on survival in patients with advanced tumors since they experienced prolonged survival. CONCLUSIONS: Plasmacytoid urothelial carcinoma is a rare variant of urothelial carcinoma with defined clinical and pathological characteristics. Diagnostic pitfalls are missing hematuria and no grossly identifiable tumor despite muscle invasive tumor stage. Cases only show mucosal induration and thickened bladder walls. Our data raise the possibility that the loss of E-cadherin expression is a prerequisite for plasmacytoid urothelial carcinoma. Awareness of these aspects should lead to earlier diagnosis and improved long-time survival in patients with plasmacytoid urothelial carcinoma.

The TNM classification integrates the currently valid prognostic factors for tumour-specific survival after radical cystectomy due to bladder cancer. But it does not contain the most important criteria for general survival. We assessed the preoperative and operative aspects of our patients between 1992 and 2007 concerning the early mortality within the hospital stay or within 30 days after surgery. 3% of our 404 patients died within these periods, which is equivalent to the results of other contemporary publications. Except for the comorbidity of the patients, none of the included parameters (initial symptoms, histology, indication for cystectomy, AJCC stadium, year of surgery, durance of surgery, surgeon, concomitant interventions, type of urinary diversion, blood loss and number of transfusions) showed a significant correlation to cause or postoperative time of death. For the preoperative assessment of the health of the patient a multidisciplinary cooperation of urology, anaesthesia and general and/or internal medicine is necessary. In the era of evidence-based medicine the personal judgement of the evaluating physician is not sufficient. Instead a validated index should be used to help one to obtain an objective evaluation of the risks. The ACE-27 (Adult Comorbidity Evaluation-27) provides such a validated assistance in the assessment of the comorbidity of patients and therefore possible mortality after radical cystectomy.

Bladder cancer represents the fifth most common malignancy in the US. In Germany we face 25,000 new incidences of urothelial cancers every year. At present a variety of different techniques is available for the diagnosis of bladder cancer. On the one hand techniques are needed that show the possible presence of a tumour and on the other hand procedures that can confirm a lesion to be a tumour, like in most cases histology does. The following article gives an overview of the currently used standards in the diagnosis of urothelial cancer. Also new techniques for diagnosis and surveillance of urothelial cancer are discussed. The combination of white light endoscopy and urine cytology is currently considered the gold standard for diagnosis. Transurethral biopsies or TUR-BT subsequently follow in the case of positive findings. To optimize the sensitivity and lower the recurrence rate as well as the residual tumour rate, fluorescence endoscopy can be used as an additional approach. Also urine-based markers play an important role in the diagnosis and surveillance of urothelial carcinomas, but cannot yet be recommended as a single procedure in the routine diagnosis of bladder tumour.

PURPOSE: T1G3 bladder cancers show the clinical and biological behaviour of muscle invasive tumours with progression rates of about 30%. While radical cystectomy in some cases is indicated, other patients can achieve healing with organ preservation. We present a study analysing the influence of the risk factors multifocality, tumour diameter >or= 3 cm and associated carcinoma in situ (Cis) on the outcome of initial T1G3 bladder cancers treated in various ways. MATERIALS AND METHODS: Of 223 patients with initial T1G3 bladder cancer, 125 patients underwent transurethral resection of the tumour (TURB), second resection and adjuvant bacille Calmette-Guérin (BCG) instillations (TURB group), 98 patients chose initial radical cystectomy (CX group). RESULTS: Median follow-up times were 56 months (TURB group) and 51 months (CX group). 5- and 10-year survival rates (82% and 65% in TURB group vs. 75% and 48% in CX group) did not show statistically significant differences. In Cox regression analysis no single risk factor showed a prognostic value. While in TURB group the combination of all risk factors (multifocality, tumour diameter >or= 3 cm and associated carcinoma in situ) was associated with a statistically significantly lower survival rate, the same combination in the CX group was not oncologically relevant. CONCLUSIONS: While initial T1G3 bladder cancer with up to two risk factors after organ-preserving therapy is not associated with a lower tumour specific survival rate in comparison to radical cystectomy, patients with a combination of the three analysed risk factors would profit by an early radical cystectomy.
