Examining longitudinal markers of bladder cancer recurrence through a semiautonomous machine learning system for quantifying specimen atypia from urine cytology. Cancer Cytopathol 2023; 131:561-573. [PMID: 37358142 PMCID: PMC10527805 DOI: 10.1002/cncy.22725] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Revised: 03/31/2023] [Accepted: 04/20/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Urine cytology is generally considered the primary approach for screening for recurrence of bladder cancer. However, it is currently unclear how best to use cytological examinations for assessment and early detection of recurrence, beyond identifying a positive finding that requires more invasive methods to confirm recurrence and decide on therapeutic options. Because screening programs are frequent, and can be burdensome, finding quantitative means to reduce this burden for patients, cytopathologists, and urologists is an important endeavor and can improve both the efficiency and reliability of findings. Additionally, identifying ways to risk-stratify patients is crucial for improving quality of life while reducing the risk of future recurrence or progression of the cancer. METHODS In this study, a computational machine learning tool, AutoParis-X, was leveraged to extract imaging features from urine cytology examinations longitudinally to study the predictive potential of urine cytology for assessing recurrence risk. This study examined how the significance of imaging predictors changes over time before and after surgery to determine which predictors and time periods are most relevant for assessing recurrence risk. RESULTS Results indicate that imaging predictors extracted using AutoParis-X can predict recurrence as well or better than traditional cytological/histological assessments alone and that the predictiveness of these features is variable across time, with key differences in overall specimen atypia identified immediately before tumor recurrence. CONCLUSIONS Further research will clarify how computational methods can be effectively used in high-volume screening programs to improve recurrence detection and complement traditional modes of assessment.

Is Regular Radiographic Upper Urinary Tract Imaging for Surveillance of Non-Muscle Invasive Bladder Cancer Justified? Cancers (Basel) 2022; 14:cancers14225586. [PMID: 36428679 PMCID: PMC9688179 DOI: 10.3390/cancers14225586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 11/02/2022] [Accepted: 11/11/2022] [Indexed: 11/16/2022] Open
Abstract
Patients with non-muscle invasive (NMI) urothelial bladder cancer (BC) are at increased risk for the development of a secondary upper-urinary-tract urothelial carcinoma (UTUC). We aimed to assess the usefulness of routine upper-tract imaging surveillance during NMIBC follow-up in a patient cohort of a tertiary academic center. All routine upper-tract-imaging scans using computerized tomography urography (CTU) between 2003 and 2016 were assessed for UTUC detection. A total of 315 patients were analyzed. Initial tumor stage was Ta in 207 patients (65.7%), T1 in 98 patients (31.1%) and pure CIS in 10 patients (3.2%). A total of 149 (47.3%) presented with low-grade (LG), and 166 (52.7%) with high-grade (HG) disease. Median follow-up was 48 months (IQR: 55). Four patients (1.2%) were diagnosed with UTUC during follow-up. All four patients presented with initial Ta HG BC. Two of the patients (50%) were diagnosed by routine upper tract imaging. The other two patients were diagnosed after development of symptoms. The 5- and 10-year UTUC-free survival was 98.5% (standard error (SE) 0.9) and 97.6% (SE 1.3), respectively. UTUCs were detected exclusively in patients with initial HG disease, indicating that upper-tract surveillance might only be necessary in these patients.

Challenging Visualization of Sentinel Lymph Nodes in Upper Urinary Tract Urothelial Carcinoma. J Clin Med 2021; 10:jcm10235465.

Abstract
Purpose: The purpose of this study was to assess the possibility of detecting sentinel lymph nodes (SLNs) and to perform analysis of lymphatic outflow in patients with suspicion of upper tract urothelial carcinoma (UTUC) with the use of a radioisotope-based technique. Methods: During 2018–2021, a prospective study was conducted on 19 patients with the suspicion of UTUC and for whom diagnostic ureterorenoscopy (URS) was planned. Technetium-99m (99mTc) nanocolloid radioactive tracer injection and a tumor biopsy were performed for staging procedures. Three-dimensional (3D) reconstruction and fusion of images were performed for better localization of lymph nodes (LNs). Detection of SLNs and the analysis of the radiotracer outflow was conducted with the use of single-photon emission-computed tomography/computed tomography (SPECT/CT) lymphangiography. Results: The mean age of the patients was 73.4 years; 7 (36%) were male. Pathological staging from the biopsy was T0—8 (42%), Ta—7 (36%), T1—4 (21%). SLNs were detected in two of 19 cases (10%). In one patient a single SLN (5.3%) was visualized, and in another case (5.3%), multiple (double) radioactive lymph nodes were visualized. In 17 out of the 19 (89.5%) cases, no lymphatic outflow was observed, and out of these five cases (26.3%) of gravitational leakage of injected radiotracer to the retroperitoneal space was noted. Conclusions: We demonstrated that detection of SLNs in the upper urinary tract is possible yet challenging. Radiotracer injection in the upper urinary tract during ureterorenoscopy is difficult to perform, and the expected result of injection is unsatisfactory. Lymphatic outflow from the tumor site to the first LNs in our studied group of patients is visible in 10.5% of cases. SPECT/CT lymphangiography in cases of UTUC may provide valuable information about a patient’s individual anatomy of the lymphatic system and the position of the first lymph nodes draining lymph with potential metastatic cells from the tumor.

Abstract
Objective To summarise the currently available literature and analyse available results of the outcome of intraoperative frozen-section analysis (FSA) on upper urinary tract recurrence (UUTR) after radical cystectomy (RC). Materials and methods A systematic review of the literature was performed according to the Cochrane Reviews guidelines and in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Articles discussing ureteric FSA with RC were identified. Results The literature search yielded 21 studies, on which the present analysis was done. The studies were published between 1997 and 2019. There were 10 010 patients with an age range between 51 and 95 years. Involvement of the ureteric margins was noted in 2–9% at RC. The sensitivity and specificity of FSA were ~75% and 99%, respectively. Adverse pathology on FSA and on permanent section, prostatic urothelial carcinoma involving the stroma but not prostatic duct, and ureteric involvement on permanent section were all more likely to develop UUTR. Neither evidence of ureteric involvement nor ureteric margin status on permanent section were significant predictors of overall survival. Conclusion Routine FSA is mandatory for a tumour-free uretero–enteric anastomosis and is predictive of UUTR. To lower the UUTR, FSA is not necessary if the ureters are resected at the level where they cross the common iliac vessels. FSA is indicated whenever the surgeon encounters findings suspicious of malignancy, e.g. ureteric obstruction, periureteric fibrosis, diffuse carcinoma in situ, induration or frank tumour infiltration of the distal ureter is discovered unexpectedly during surgery, and prostatic urethral involvement. Abbreviations CIS: carcinoma in situ; FSA: frozen-section analysis; HR: hazard ratio; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; RC: radical cystectomy; (UT)UC: (upper tract) urothelial carcinoma; UUT(R): upper urinary tract (recurrence)

Abstract
Upper tract urinary carcinoma (UTUC) and bladder cancer (BCa) share similar biological, histological and pathological characteristics. These resemblances could explain the high rate of synchronous and metachronous tumors affecting both upper urinary tract and bladder. In patients affected by primary UTUC bladder recurrence is quite common and it represents one of the major concerns during the follow-up of patients who underwent radical nephroureterectomy. Conversely, UTUC recurrence after primary non-muscular invasive BCa is a relatively rare event. Moreover, there is no clear evidence on whether the use of Double-J stenting as drainage in patients affected by BCa increases the risk of UTUC recurrence. The aim of the current study was to summarize the most recent evidence regarding the bladder recurrence after UTUC surgical treatment, and the UTUC recurrence after stent positioning in patients affected by primary BCa.

Abstract
Urothelial carcinoma in the upper tract is rare and often discussed separately. Many established risk factors were identified for the disease, including genetic and external risk factors. Radiographic survey, endoscopic examination and urine cytology remained the most important diagnostic modalities. In localized upper tract urothelial carcinomas, radical nephroureterectomy with bladder cuff excision are the gold standard for large, high-grade and suspected invasive tumors of the renal pelvis and proximal ureter, whereas kidney-sparing surgeries should be considered in patients with low-risk disease. Advances in technology have given endoscopic surgery an important role, not only in diagnosis, but also in treatment. Although platinum-based combination chemotherapy is efficacious in advanced or metastatic disease, current established chemotherapy regimens are toxic and lack a sustained response. Immune checkpoint inhibitors have led to a new era of treatment for advanced or metastatic urothelial carcinomas. The remarkable results achieved thus far show that immunotherapy will likely be the future treatment paradigm. The combination of immune checkpoint inhibitors and other agents is another inspiring avenue to explore that could benefit even more patients. With respect to the high incidence rate and different clinical appearance of upper tract urothelial carcinomas in Taiwan, a possible correlation exists between exposure to certain external risk factors, such as arsenic in drinking water and aristolochic acid in Chinese herbal medicine. As more gene sequencing differences between upper tract urothelial carcinomas and various disease causes are detailed, this has warranted the era of individualized screening and treatment for the disease.

Abstract
The mechanism of upper tract recurrence after local excision of bladder cancer remains unknown. This study was designed to identify risk factors for upper tract urothelial recurrence following local tumor excision of bladder cancer. To identify 76 597 bladder cancer patients, comprising 76 537 nonrecurrence and 60 recurrence patients, the Surveillance, Epidemiology, and End Results database was used. Kaplan‐Meier analysis and univariate and multivariate Cox proportional hazards regression models were used to determine the risk factors. Compared with the nonrecurrence group, the recurrence group was associated with older age, higher grade, high T stage, and higher proportional squamous cell carcinomas. Univariate Cox proportional hazards regression model showed that age, grades III and IV, T stage, and pathology were significantly associated with worse upper tract urothelial recurrence (UTUR) survival. However, after adjusting for prognostic factors, grade was no longer an independent prognostic factor in multivariate analysis. This study demonstrates that clinical prognosis of UTUR after local bladder tumor excision has significant independent risk factors that include age ≥60 years, T1 and T2 stage, and squamous cell carcinoma, and will require more careful consideration during follow‐up.

Abstract
Many pathological processes including neurogenic bladder and malignancy necessitate bladder reconstruction, which is currently performed using intestinal tissue. The use of intestinal tissue, however, subjects patients to metabolic abnormalities, bladder stones, and other long-term sequelae, raising the need for a source of safe and reliable bladder tissue. Advancements in stem cell biology have catapulted stem cells to the center of many current tissue regeneration and bioengineering strategies. This review presents the recent advancements in the use of stem cells in bladder tissue bioengineering.

Abstract
The effect of pre-operative renal insufficiency on urothelial carcinoma (UC) prognosis has been investigated by numerous studies. While the majority report worse UC outcomes in patients with renal insufficiency, the results between the studies differed wildly. To enable us to better estimate the prognostic value of renal insufficiency on UC, we performed a systematic review and meta-analysis based on the published literature. A total of 16 studies which involved 5,232 patients with UC, investigated the relationship between pre-operative renal insufficiency and disease prognosis. Estimates of combined hazard ratio (HR) for bladder urothelial carcinoma recurrence, cancer-specific survival (CSS) and overall survival (OS) were 1.65 (95% CI, 1.11–2.19), 1.59 (95% CI, 1.14–2.05) and 1.45 (95% CI, 1.19–1.71), respectively; and for upper urinary tract urothelial carcinoma recurrence, CSS and OS were 2.27 (95% CI, 1.42–3.12), 1.02 (95% CI, 0.47–1.57) and 1.52 (95% CI, 1.05–1.99), respectively. Our results indicate that UC patients with pre-operative renal insufficiency tend to have higher recurrence rates and poorer survival compared to those with clinically normal renal function, thus renal function should be closely monitored in these patients. The impact of intervention for renal insufficiency on the prognosis of UC needs to be further studied.

Abstract
BACKGROUND Patients with urothelial carcinoma (UC) often develop multifocal metachronous tumors throughout the genitourinary tract. In the present study, we evaluated the prognostic value of prior history of UC of the bladder (UCB) in patients with upper tract urothelial carcinoma (UTUC) in an international multi-institutional cohort. PATIENTS AND METHODS Data from 785 patients who underwent radical nephroureterectomy (RNU) with ipsilateral bladder cuff resection at nine academic institutions in Europe and the USA between 1987 and 2008 were reviewed. Log-rank tests and Cox proportional hazards regression models were used for univariable and multivariable analyses. RESULTS The median follow-up of the whole cohort was 34 months (interquartile range 15-66 months). Five hundred and fifty-eight (72 %) patients had no UCB before the diagnosis of UTUC; a prior history of non-muscle-invasive and muscle-invasive UCB before the UTUC was found in 179 (23 %) and 36 (5 %), respectively. History of UCB before RNU was an independent predictor of both recurrence-free survival (p = 0.012; no UCB vs. non-muscle-invasive UCB: hazard ratio (HR) 1.4, p = 0.082; no UCB vs. muscle-invasive UCB: HR 2.1, p = 0.007) and cancer-specific survival (p = 0.008; no UCB vs. non-muscle-invasive UCB: HR 1.2, p = 0.279; no UCB vs. muscle-invasive UCB: HR 2.3, p = 0.008) on multivariable Cox regression analyses that included age, gender, surgical type, stage, grade, presence of concomitant carcinoma in situ, presence of lymphovascular invasion, and lymph node status. CONCLUSIONS Prior history of muscle-invasive UCB was significantly associated with an increased risk of disease recurrence and cancer-specific death in patients with UTUC.

Abstract
Objective The aim of this study is to examine the incidence and risk factors of upper urinary tract recurrence (UUTR) following radical cystectomy (RC) in bladder cancer and to evaluate its relationship with neobladder (Neo) or ileal conduit (IC). Materials and Methods All clinicopathologic parameters and perioperative parameters of 311 patients who underwent RC with either Neo or IC by a single surgeon from 1999 to 2012 were retrospectively included in this study. Patients with a history of renal surgery, concomitant UUTR, or a histopathology of non-transitional cell carcinoma were excluded. For statistical analyses of predictive risk factors of UUTR, a multivariate analysis was performed with known risk factors of UUTR, including type of urinary diversion with significance defined as P < 0.05. Results During the median follow-up period of 53 months, 143 (46.0%) IC and 168 (54.0%) Neo were performed, resulting in 11 (3.5%) cases of UUTR (Neo 7 and IC 4) after RC and all patients then underwent nephroureterectomy. No significant differences in incidence and overall survival in UUTR were observed according different types of urinary diversion (p = 483), and the prognosis for survival of Neo was insignificantly better than that of IC (5-year overall survival 78% vs 74%, respectively, p>0.05). Higher number of positive lymph nodes (HR 9.03) and the presence of pelvic local recurrence (HR 7286.08) were significant predictive factors of UUTR (p<0.05). Conclusion This study reports a UUTR rate of 3.5%, and positive lymph nodes and presence of local recurrence at the pelvis as important risk factors. No significant differences in incidence and survival were observed between Neo and IC.

Abstract
OBJECTIVES To identify predictive factors of bladder recurrence after radical nephroureterectomy and to evaluate the impact of this event on oncological outcomes. METHODS We carried out a retrospective analysis of 237 patients treated with radical nephroureterectomy for urothelial carcinoma of the upper tract at our institution from 1998 to 2011. Univariable and multivariable models evaluated the prognostic factors of bladder recurrence, and its impact on recurrence-free survival and cancer-specific survival. RESULTS The median age was 69.3 years (interquartile range 60-76). With a median follow up of 44 months (interquartile range 24-79), bladder recurrence occurred in 85 patients (35.9%). A previous history of bladder cancer (P = 0.01) and the presence of concomitant carcinoma in situ (P = 0.005) remained independent predictors of bladder recurrence. The presence of bladder recurrence was not correlated with worse oncological outcomes in terms of disease recurrence (P = 0.075) and cancer-specific mortality (P = 0.06). However, the patients who experienced muscle-invasive bladder cancer recurrence had worse outcomes in terms of cancer-specific mortality (P = 0.01). Standard pathological features of aggressiveness, such as higher tumor stage (P = 0.05), higher grade (P = 0.01) and carcinoma in situ (P = 0.03), were independent predictors of muscle-invasive bladder cancer recurrence. CONCLUSIONS Previous history of bladder cancer, tumor location and concomitant carcinoma in situ are independent predictors of bladder recurrence in patients undergoing radical nephroureterectomy. Bladder recurrence overall does not impact the oncological outcomes, but a muscle-invasive bladder recurrence is associated with a worse cancer-specific mortality. Standard pathological features of urothelial carcinoma of the upper tract aggressiveness (pT-stage, grade) are independent predictors of muscle-invasive bladder cancer recurrence.

Prognostic significance of tumor location and superficial urothelial bladder carcinoma history in patients with ureteral urothelial carcinoma treated with radical nephroureterectomy. Int Urol Nephrol 2013; 45:395-404.

Abstract
PURPOSE To investigate the significance of tumor location and superficial urothelial bladder carcinoma (UBC) history on oncological outcomes in patients treated with radical nephroureterectomy (RNU) for ureteral urothelial carcinoma (UC). METHODS One hundred and thirty-two patients treated with RNU for ureteral UC between January 1999 and July 2010 were retrospectively analyzed. Recurrence probabilities and survival rates were analyzed, stratified by tumor location and superficial UBC history. RESULTS Comparison of patients with proximal, middle, and distal ureteral UC showed that percentage of bladder recurrence was 13.3, 14.7, and 25.0 %, respectively (P = 0.285); retroperitoneal (tumor bed or lymph node) recurrence was 26.7, 14.7, and 27.9 % (P = 0.319); and contralateral recurrence was 0, 2.9, and 0 % (P = 0.234). Comparison of patients with and without history of superficial UBC revealed that percentage of bladder recurrence was 15.4 and 20.2 %, respectively (P = 0.681); retroperitoneal recurrence was 15.4 and 25.2 % (P = 0.433); and contralateral recurrence was 0 and 0.84 % (P = 0.740). Using multivariable Cox regression analyses, there were no significant differences of recurrence-free survival (RFS) and cancer-specific survival (CSS) with regard to neither tumor location nor superficial UBC history (RFS: P = 0.282 and 0.762, CSS: P = 0.272 and 0.818, respectively). CONCLUSIONS Tumor location and history of superficial UBC could not be used to predict oncological outcomes of patients who underwent RNU for ureteral UC. Therefore, operative strategies or postoperative surveillance should not be affected by tumor location or history of superficial UBC.

Abstract
OBJECTIVES To identify predictive factors and assess the impact on oncological outcomes of intravesical recurrence after radical nephroureterectomy (RNU) in upper tract urothelial carcinoma (UTUC). METHODS Using a national multicentric retrospective dataset, we identified all patients with UTUC who underwent a RNU between 1995 and 2010 (n = 482). Intravesical recurrence was tested as a prognostic factor for survival through univariable and multivariable Cox regression analysis. RESULTS Overall, intravesical recurrence occurred in 169 patients (35 %) with a median age of 69.2 years (IQR: 60-76) and after a median follow-up of 39.5 months (IQR: 25-60). Actuarial intravesical recurrence-free survival estimates at 2 and 5 years after RNU were 72 and 45 %, respectively. On univariable analyses, previous history of bladder tumor, tumor multifocality, laparoscopic approach, pathological T-stage, presence of concomitant CIS and lymphovascular invasion were all associated with intravesical recurrence. On multivariable analysis, previous history of bladder cancer, tumor multifocality and laparoscopic approach remained independent predictors of intravesical recurrence. Existence of intravesical recurrence was not correlated with worst oncological outcomes in terms of disease recurrence (p = 0.075) and cancer-specific mortality (p = 0.06). CONCLUSIONS In the current study, intravesical recurrence occurred in 35 % of patients with UTUC after RNU. Previous history of bladder cancer, tumor multifocality, concomitant CIS and laparoscopic approach were independent predictors of intravesical recurrence. These findings are in line with recent published data and should be considered carefully to provide a definitive surveillance protocol regarding management of urothelial carcinomas regardless of the location of urothelial carcinomas in the whole urinary tract.

Abstract
PURPOSE To compare contrast material-enhanced computed tomographic (CT) urography 60 seconds after injection of contrast material (urothelial phase [UP]) after intravenous administration of a diuretic with the standard 5-minute delayed excretory phase (EP) in a high-risk population for upper tract tumors. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. Eighty CT urographic examinations in 77 patients known to have or at high risk for urothelial malignancy were included. After intravenous administration of a diuretic, dual-phase CT urography was performed at 60 seconds (UP) and 5 minutes (EP) after intravenous administration of contrast material. Two experienced abdominal radiologists independently interpreted each phase more than 1 month apart to minimize recall bias. Urinary tract distention and location and size of all lesions suspected of being urothelial tumors were recorded. Standard of reference was obtained from prospective study interpretation and surgical histopathologic findings. Generalized estimating equations for logistic regression were used to compare performance measures and adjust for the correlation of repeated measures within patients. RESULTS There were 23 upper and 61 lower urinary tract tumors confirmed in 15 and 32 patients, respectively. For detection of bladder tumors, there was higher sensitivity for the UP than the EP (89.3% [109 of 122] vs 70.5% [86 of 122], respectively; P<.0001). For detection of upper tract tumors, there was higher sensitivity for the UP than the EP (82.6% [38 of 46] vs 69.6% [32 of 46], respectively; P=.0194). Distention of all upper urinary tract segments was better during the EP than the UP (P<.0001). CONCLUSION UP CT urography after injection of a diuretic has a higher lesion detection rate than the EP for both upper and lower urinary tract tumors, which suggests its possible use as a single-phase protocol for evaluation of the entire urinary tract in patients at high risk for urothelial tumors.

Abstract
OBJECTIVE Nephroureterectomy with bladder cuff excision has been the gold standard treatment for upper tract transitional cell carcinoma (UTTCC) for more than 60 years. However, endoscopic treatment of urothelial tumours of renal pelvis and ureter is gaining acceptance as a conservative treatment modality. MATERIAL AND METHODS A review in the English language of the Medline and Pub Med databases was performed using the keywords upper urinary tract transitional cell carcinoma and endoscopic management. There was a particular emphasis on treatment outcomes from published series. RESULTS Endoscopic treatment of UTTCC alone for high-grade tumours is not advised owing to high rates of both local recurrence and disease progression, while many authors do not recommend primary endoscopic management of UTTCC in elective situations if pathological analysis and tumour grade cannot be obtained. CONCLUSION Endourological management of UTTCC has become an accepted treatment option in highly selected patients, provided long-term close surveillance to detect and treat recurrences is ensured.

In the cystoscopic follow-up of non-muscle-invasive transitional cell carcinoma, NMP-22 works for high grades, but unreliable in low grades and upper urinary tract tumors. Int Urol Nephrol 2012; 44:793-8.

Abstract
INTRODUCTION AND OBJECTIVES Two percent of the bladder non-muscle-invasive (NMI) transitional cell carcinomas (TCC) are associated with upper urinary tract (UUT) TCC. We evaluated the role of nuclear matrix protein-22 (NMP-22) (BladderChek) test in the diagnosis of lower urinary tract and UUT-TCC. METHODS From March 2009 to June 2011, 122 patients with bladder NMI-TCC underwent 205 control cystoscopy. A total of 95 (78 men and 17 women, mean age 60.7 years, range, 27-88) patients who were followed regularly with NMP-22 test and with follow-up cystoscopies (145 episodes; min. 1-max. 5) were included in this study. For routine monitoring of the UUT, IVU or CT urography was used once a year for high grades (HG), and once in every other year for low grades (LG). The sensitivity and specificity of NMP-22 were evaluated by ROC curves, and sensitivity, specificity, and positive and negative predictive values were calculated. Chi-square test was used for the differences between the subgroups. RESULTS Cystoscopy and NMP-22 results of the patients included in the study revealed the sensitivity (44.4%) of the test was very low and the specificity (98.4%) was quite high (p < 0.001). Among the 10 cystoscopies where NMP-22 was negative, but cystoscopy was positive for tumor, 8 had LG and 2 had HG TCC. NMP-22 was never positive in low-grade tumors, in other words, all of the NMP-22-positive 8 tumors were high grade. On the other hand, in 20% (2/10) of the cases, NMP-22 can be negative although the tumor was high grade. Two (2.1%) HG UUT-TCC were detected in 95 patients. These 2 patients were within the 125 cystoscopies (75 patients) where both NMP-22 and cystoscopy were negative for tumor. CONCLUSIONS Nuclear matrix protein-22 cannot detect LG TCC. However, it detects overwhelming majority of HG TCC. For this reason, positive NMP-22 test largely indicates HG TCC. NMP-22 is also not reliable in UUT-TCC, even in HG tumors.

Abstract
Upper urinary tract (UUT) transitional cell carcinoma (TCC) is relatively rare tumor. Approximately 0.7-4% of patients with primary bladder cancer develops UUT-TCC. The symptoms related to an UUT-TCC often occur with an advanced stage which leads one to emphasize a surveillance strategy to monitor the UUT to allow for an earlier diagnosis. Although the risk of UUT-TCC after bladder cancer is well established, there is a paucity of recommendations suggesting the optimal method and frequency of monitoring the UUT and there is no consensus among them. This article reviews the recommendations on monitoring the UUT in patients with bladder cancer.

Abstract
Purpose The aim of this study was to evaluate the prognostic factors for survival in patients treated surgically for transitional cell carcinoma of the upper urinary tract (UUT-TCC). Materials and Methods We retrospectively reviewed the medical records of 87 patients (64 men and 23 women, mean age of 62.2 years) with UUT-TCC who had undergone radical nephroureterectomy at our institution between June 1994 and June 2009. The median follow-up period was 32 months. The prognostic significance of various clinicopathological variables for recurrence-free and cancer-specific survival was analyzed by using univariate and multivariate analysis. Results Of the total 87 patients, 21 patients (24.1%) developed local recurrence or distant metastasis and 16 patients (18.4%) died of disease during the follow-up period. The 5-year recurrence-free and cancer-specific survival rates were 74.6% and 75.2%, respectively. In the univariate analysis, hydronephrosis, T stage, N stage, and lymphovascular invasion (LVI) were significant prognostic factors for recurrence-free and cancer-specific survival. In the multivariate analysis, T stage and LVI were independent prognostic factors for recurrence-free and cancer-specific survival. Conclusions The T stage and LVI are independent prognostic factors for recurrence-free and cancer-specific survival in patients with UUT-TCC treated by radical nephroureterectomy. These findings would be helpful for guiding decisions about adjuvant therapies and the surveillance interval.

Abstract
OBJECTIVES To determine the effect of age on the disease characteristics, treatment administered, and disease-specific survival (DSS) for patients with upper tract urothelial carcinoma. The effect of advancing age on the disease extent and survival has not been well delineated in patients with upper tract urothelial carcinoma. METHODS Using the Surveillance, Epidemiology, and End Results database from the National Cancer Institute, we identified patients diagnosed with UTUC from 1984 to 2004. The data were analyzed for age (40-49, 50-59, 60-69, 70-79, and ≥80 years), sex, race, disease extent, treatment type, and cause of death. Relationships among age, clinicopathologic features, and treatment were tabulated. The effect of age on overall and DSS were calculated using Cox proportional hazards ratio analyses. RESULTS The final cohort consisted of 12 639 patients. Advancing age was associated with greater T stage and grade at presentation. Of those 40-49 years old, 41% presented with invasive tumors (T2-T4) compared with 50% of octogenarians. Poor or undifferentiated tumors increased in frequency from 42% among those 40-49 years old to 59% among those≥80 years old. Extirpative surgery was less likely among those with Stage T1 or less disease (88.3% vs 92.8%). Octogenarians were less likely to have undergone extirpative surgery than those 40-49 years old (86% vs 95%). Despite adjustments for T stage, grade, and treatment, DSS (hazard ratio 2.64) worsened with increasing age. CONCLUSIONS With advancing age, we found a corresponding increase in stage and grade at presentation. After adjustment for stage, grade, and treatment type, older patients still had worse DSS.

Abstract
OBJECTIVES To evaluate the effect of a history of bladder carcinoma in situ (CIS) on relapse and survival after surgical management of metachronous upper tract urothelial carcinoma (UTUC). Urinary bladder CIS was previously reported to be among the independent risk factors for the development of UTUC. METHODS Using a multi-institutional database of patients treated with radical nephroureterectomy (RNU) for UTUC, we compared the clinicopathologic parameters and clinical outcomes of patients with and without a history of bladder CIS. Multivariate Cox regression analysis was performed to determine the independent predictors of disease recurrence and cancer-specific mortality after RNU. RESULTS The study included 1316 patients, 884 men and 432 women, with median follow-up of 36 months after RNU. The patients with a history of bladder CIS (n = 91) were more likely to have high-grade and sessile UTUC (P < .05). The 5 year disease-free survival and cancer-specific survival rate was 53% and 59% in those with a history of bladder CIS and 71% and 75% in those without a history of bladder CIS, respectively (P = .031 and P = .045, respectively). On multivariate Cox regression analysis, a history of bladder CIS was an independent predictor of disease recurrence and cancer-specific mortality after RNU (P = .006 and P = .045, respectively). CONCLUSIONS The results of our study have shown that patients with a history of bladder CIS are more likely to develop aggressive UTUC and demonstrate a greater risk of recurrence and death from cancer after RNU. Our findings suggest the need for aggressive surveillance regimens and multimodal management strategies for patients who develop UTUC in the setting of previous bladder CIS.

Abstract
PURPOSE Tumor necrosis is associated with a poor oncological outcome in patients with upper tract urothelial carcinoma and other malignancies. We validated the association of tumor necrosis with pathological features and clinical outcomes in a large international cohort of patients with upper tract urothelial carcinoma treated with radical nephroureterectomy. MATERIAL AND METHODS This retrospective study included 754 patients treated with radical nephroureterectomy at a total of 9 centers. Tumor necrosis was scored as greater than 10% of tumor area based on microscopic evaluation. RESULTS Tumor necrosis was present in 165 specimens (21.9%). The prevalence of tumor necrosis increased with advancing pathological stage, including 7%, 10.6% and 50% for T1, T2 and T3-4, respectively (p <0.001). Tumor necrosis was associated with features of aggressive upper tract urothelial carcinoma, such as high grade, lymph node metastasis, lymphovascular invasion, sessile tumor architecture and concomitant carcinoma in situ (p <0.002). Median followup in censored patients was 40 months (IQR 18 to 75). On univariate Cox regression analysis tumor necrosis was significantly associated with disease recurrence and cancer specific mortality (HR 2.4 and 2.7, p <0.001). However, on multivariate Cox regression analysis including patient age, stage, grade, lymph node status, lymphovascular invasion and adjuvant chemotherapy tumor necrosis was not associated with disease recurrence (HR 1.1, p = 0.49) or cancer specific mortality (HR 1.1, p = 0.51). Excluding 63 patients who received adjuvant chemotherapy and/or 49 with positive lymph nodes did not substantially change these results. CONCLUSIONS In this large, multicenter international study tumor necrosis was associated with pathological features of biologically aggressive upper tract urothelial carcinoma. However, tumor necrosis was not an independent predictor of clinical outcomes.

Abstract
The concept of examining the body's interior and its organs dates back to ancient times. The roots of modern endoscopy lie in early nineteenth century Europe, and the intervening centuries have seen a steady evolution of devices and techniques. Nowadays, a wide variety of urinary tract disorders are successfully managed in a minimally invasive manner thanks to the endoscope and related technologies. Distal-sensor, 'digital', endoscopes have the potential to revolutionize the field, and change the way in which we use and think about endoscopy. Virtual endoscopy, capsule endoscopy, and a range of other techniques derived from physics and molecular biology all promise great improvements in visualization of the urinary tract and other urologic structures. Ultimately, the continued improvement of these minimally invasive technologies will enhance the quality of care that we can offer our patients.

Abstract
BACKGROUND Lymphovascular invasion (LVI) identified following pathologic slide review has been shown to be an independent predictor of recurrence-free survival (RFS) and cancer-specific survival (CSS) in a multicenter series of patients undergoing radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC). However, the validity of LVI in everyday practice, where pathologic re-review of all slides is uncommon, has not been assessed. OBJECTIVE Our aim was to evaluate the prognostic role of LVI in an international cohort of patients treated with RNU for UTUC without pathologic slide review. DESIGN, SETTING, AND PARTICIPANTS Data from 762 patients treated with RNU for UTUC without neoadjuvant chemotherapy were collected at nine centers located in Europe, Asia, and Canada. MEASUREMENTS We evaluated patients' characteristics, RFS, and CSS. RESULTS AND LIMITATIONS LVI was present in 148 patients (19.4%). At a median follow-up of 34 mo, 23.5% of the patients developed disease recurrence and 19.8% died of UTUC. The 5-yr RFS and CSS rates were 79.3% and 82.1%, respectively, in the absence of LVI compared with 45.1% and 45.8%, respectively, in the presence of LVI (p values <0.0001). On multivariable Cox regression analyses, LVI was an independent predictor of RFS (hazard ratio [HR]: 3.3; p=0.005) and CSS (HR: 5.9; p<0.0001). Similarly, among patients with pN0/Nx disease, LVI was an independent predictor of RFS (HR: 2.1; p=0.001) and CSS (HR: 2.3; p<0.0001). CONCLUSIONS In a large multicenter series of patients treated with RNU for UTUC and for which no pathologic slide review was performed, LVI was present in approximately 20% and was an independent predictor of both RFS and CSS. LVI status should always be included in the pathologic report of RNU specimens, and patients with LVI should be considered for adjuvant therapy studies.

Abstract
PURPOSE The prognostic significance of renal pelvis vs ureteral upper urinary tract urothelial carcinoma tumor location is controversial. We assessed the prognostic significance of upper urinary tract urothelial carcinoma tumor location in a large, population based data set. MATERIALS AND METHODS Our analyses relied on 2,824 patients treated with nephroureterectomy for upper urinary tract urothelial carcinoma within 9 SEER registries between 1988 and 2004. Univariable and multivariable models tested the effect of tumor location on cancer specific mortality rates. Covariates consisted of age, race, SEER registry, gender, type of surgery (nephroureterectomy with vs without bladder cuff removal), pT stage, pN stage, grade and year of surgery. RESULTS Relative to ureteral tumors renal pelvis tumors were of higher stage (T3/T4 disease 38.4% vs 57.9%, p <0.001) and had a higher rate of lymph node metastases (6.0% vs 9.8%, p = 0.003) at nephroureterectomy. The respective 5-year cancer specific mortality-free survival estimates were 81.0% vs 75.5% (p = 0.007). However, after multivariable adjustment tumor location failed to reach independent predictor status of cancer specific mortality (p = 0.8). CONCLUSIONS To our knowledge this is the largest cohort in which the impact of upper urinary tract urothelial carcinoma tumor location on cancer specific mortality was examined. At nephroureterectomy renal pelvis tumors had significantly more advanced T and N stages compared to ureteral tumors. However, after adjustment for stage, grade and other covariates tumor location did not independently predict cancer specific mortality. Thus, the biological behavior of renal pelvis vs ureteral tumors is the same after nephroureterectomy as long as stage, grade, and other patient and tumor characteristics are accounted for.

Abstract
The incidence of transitional cell carcinoma of the kidney and ureter is
low and for that reason limited data exists regarding the appropriate management of
regional retroperitoneal lymph nodes. Lymph node metastases have consistently
been associated with an adverse prognosis. However, five-year cancer-specific survival
following nephroureterectomy and lymphadenectomy for patients with lymph node involvement ranges
from 0–39%, suggesting a therapeutic benefit. This review covers the primary tumor characteristics
associated with lymph node involvement, imaging of the lymph nodes, as well as the rationale,
role, patient selection, suggested anatomic templates, and technical
considerations for lymphadenectomy.

Abstract
OBJECTIVE To identify significant prognostic indicators of upper urinary tract (UUT) urothelial carcinoma (UC) and to assess a risk stratification of patients. PATIENTS AND METHODS We retrospectively analysed data from 162 patients with non-metastatic UC primarily occurring in UUT treated with open nephroureterectomy. Variables assessed included age, gender, pT, tumour grade, tumour necrosis extension, pN, tumour location, multifocal location, tumour diameter, and subsequent development of a bladder tumour. Tumour necrosis was measured using commercial software (Eureka interface system, version 4.0.22, HESP technology, Menarini Diagnostics, Italy) and was classified as none, focal (<10% of tumour area) or extensive, >or=10% of tumour area). The prognostic significance of each variable on metastasis-free survival (MFS) and disease-free survival (DFS) was tested in univariable analysis with the log-rank test. Variables with significance levels of P < 0.05 according to the univariable analyses were entered into a multivariable forward-stepwise Cox regression model. RESULTS At a mean follow-up of 66 months, 20 cancer-related deaths (12.3%) were censored. In multivariable analysis, tumour diameter, pT stage and tumour necrosis were independent predictors of MFS and DFS. All events occurred in patients with extensive tumour necrosis and a tumour diameter of >or=3 cm. The median survival of patients with advanced-stage tumours, extensive necrosis and a tumour diameter of >or=3 cm were significantly impaired by increasing pT stage(P < 0.001). CONCLUSION Tumour necrosis and tumour diameter are compelling prognostic factors that deserve further study in a prospective setting to determine if their use in combination with more traditional variables, such as pT stage, might better determine prognosis and guide the follow-up and treatment of patients.

Abstract
OBJECTIVE To compare the potential of two diagnostic methods for detecting recurrence of urothelial cell carcinoma (UCC) of the bladder, by (i) detecting alterations in microsatellite DNA markers and loss of heterozygosity (LOH), and (ii) detecting aberrant gene hypermethylation, as UCC has a high recurrence rate in the urinary tract and the disease can invade muscle if new tumours are overlooked. PATIENTS AND METHODS Over 1 year, urine samples were retrieved from 40 patients already diagnosed with bladder UCC (30 pTa, two pTis, eight pT1). Samples were collected 6 months after bladder tumour resection, during the follow-up schedule. We used samples to analyse nine microsatellite markers and the methylation status of 11 gene promoters. Receiver operating characteristic curves were generated and Bayesian statistics used to create an interaction network between recurrence and the biomarkers. RESULTS During the study, 15 of the 40 patients (38%) had a tumour recurrence and 14 were identified by cystoscopy (reference method). Overall, microsatellite markers (area under curve, AUC 0.819, 95% confidence interval, CI, 0.677-0.961) had better performance characteristics than promoter hypermethylation (AUC 0.448, 0.259-0.637) for detecting recurrence. A marker panel of IFNA, MBP, ACTBP2, D9S162 and of RASSF1A, and WIF1 generated a higher diagnostic accuracy of 86% (AUC 0.92, 0.772-0.981). CONCLUSION Microsatellite markers have better performance characteristics than promoter hypermethylation for detecting UCC recurrence. These data support the further development of a combination of only six markers from both methods in urinary DNA. Once validated, it could be used routinely during the follow-up for the early detection and surveillance of UCC from the lower and upper urinary tract.

Abstract
BACKGROUND Unlike cancer of the bladder, cancer of the renal pelvis is not considered an occupational cancer and little is known about risks among women. METHODS Using the Swedish national census and cancer registry-linked data (1971-1989), we identified transitional cell cancers of the renal pelvis (N = 1,374) and bladder (N = 21,591). Correlation between cancer sites for the standardized incidence ratios (SIR) were determined using Pearson's coefficient of the log SIR. Relative risks of job exposure matrix variables were calculated using Poisson regression. RESULTS Both cancer sites were significantly elevated among women and men employed in the machine/electronics industry, sedentary work, and indoor work, and men in the metal industry. The highest proportion of the bladder (12%) and renal pelvis (14%) cancers occurred among men employed in shop and construction metal work. Risks by industry were more correlated among women (r = 0.49, P = 0.002) than men (r = 0.24, P = 0.04). Cancers of the renal pelvis were elevated in several occupational and industry groups for which there was no elevated bladder cancer risk. CONCLUSION Cancers of the renal pelvis and bladder share common occupational risk factors that may be more frequent among women. In addition, there may be some jobs that pose an increased risk specifically for cancer of the renal pelvis but not bladder.
