PURPOSE: Inflammation-based prognostic scores including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) are associated with oncologic outcomes in diverse malignancies. We evaluated the predictive value of pretreatment prognostic scores in differentiating nonmuscle invasive (NMIBC) and muscle invasive bladder cancer (MIBC). MATERIALS AND METHODS: Consecutive transurethral resection of bladder tumour (TURBT) cases from January 2011 to December 2013 were analysed retrospectively. Patient demographics, tumour characteristics and prognostic scores results were recorded. Receiver operating characteristics curves were used to determine prognostic score cutoffs. Univariate and multivariate binomial logistic regression analysis was performed to evaluate the association between variables and MIBC. RESULTS: A total of 226 patients were included, with 175 and 51 having NMIBC (stages Ta and T1) and MIBC (stage T2+) groups, respectively. Median age was 75 years and 174 patients were male. The NLR cutoff was 3.89 and had the greatest area under the curve (AUC) of 0.710, followed by LMR (cutoff<1.7; AUC, 0.650) and PLR (cutoff>218; AUC, 0.642). Full blood count samples were taken a median of 12 days prior to TURBT surgery. Multivariate logistic regression analysis identified tumour grade G3 (odds ration [OR], 32.848; 95% confidence interval [CI], 9.818-109.902; p=0.000), tumour size> or =3 cm (OR, 3.353; 95% CI, 1.347-8.345; p=0.009) and NLR> or =3.89 (OR, 8.244; 95% CI, 2.488-27.316; p=0.001) as independent predictors of MIBC. CONCLUSIONS: NLR may provide a simple, cost-effective and easily measured marker for MIBC. It can be performed at the time of diagnostic flexible cystoscopy, thereby assisting in the planning of further treatment.

OBJECTIVETo evaluate the value of taking surgical margin specimens during transurethral resection of bladder tumor(TURBT) in the diagnosis and treatment of non-muscle invasive bladder cancer.

METHODSThe data of 356 patients with non-muscle invasive bladder cancer from June 2009 to January 2014 were analyzed retrospectively. A standardized protocol were performed during TURBT in 176 patients(surgical margin group), by taking surgical margin specimens from tumor base and 'normal'-appearing margin sites. The other 180 cases merely received general TURBT (general group). To observe the positive rate of surgical margin specimens and whether the diagnosis and treatment plan changed in the surgical margin group. Using Chi-square test to compare the recurrence and progression rates between surgical margin and general groups. To compare their recurrence-free survival time by Mann-Whitney U test. Results Of these 176 surgical margin specimens, the positive rate was 19. 3% (34/176),which consists of tumor base 11. 9% (21/176) and tumor normal-appearing margin 7. 4% (13/176). Following with urothelial carcinoma Ta stage in 1. 7% (3/176), T1 stage in 5. 7% (10/176), T2 stage in 8. 0% (14/176), carcinoma in situ (Tis) in 4. 0% (7/176). Among these 176 patients final diagnosis were changed in 10. 8% (19/176) patients due to the specimens results, and 18. 2% (32/176) patients altered their treatment plans. All 356 patients with a mean follow-up of 36. 8 months (6 to 60 months). Two groups of patients(surgical margin group vs. general group) recurrence rates respectively were 22. 2% (39/176) vs. 35. 6% (64/180), recurrence-free survival time were 33. 0 months vs. 23. 5 months and progression rates were 5. 7% (10/176) vs. 10. 6% (19/180). Compared with general group, patients who were taken additional surgical margin specimens showed significantly lower recurrence rate (χ2 = 7. 677, P = 0. 007) and longer recurrence-free survival time (U = 12 605,P = 0. 001). While the progression rate showed no statistical difference between them (χ2 = 2. 825, P = 0. 121).

CONCLUSIONTaking additional surgical margin specimens during transurethral resection of bladder tumor is helpful for pathological diagnosis and the planning of further treatment.

Nonmuscle invasive (NMI) urothelial cancer (UC) is associated with varied biological potential. It is characterized by frequent recurrence and progression, which thus worsens the oncological outcome. Nearly three-quarters of NMI UCs recur within 5 years, whereas half can progress during follow-up. Progression is particularly seen in T1 and carcinoma in situ (CIS). Undoubtedly, NMI UC is one of the most expensive cancers to manage. The European Organisation for Research and Treatment of Cancer (EORTC) risk calculator is a commonly used tool for assessing the recurrence and progression potential of a newly diagnosed cancer. The parameters used in the assessment are tumor size and number, pathological stage and grade of the cancer, presence of CIS, and prior recurrence rate. The main advantages of the EORTC tool are its ease of use and the lack of need to run expensive molecular tests. However, reproducibility of pathologic stage and grade is modest, which is a concern to clinicians. Molecular markers have potential for predicting the clinical outcome of NMI UC, given that clinico-pathologic variables are not sufficient for prediction of prognosis in an individual. Significant work has been done in the past 2 decades in understanding the molecular biology of bladder cancer; however, the translational value of this knowledge remains poor. The role for molecular markers in predicting recurrence seems limited because multifocal disease and incomplete treatment are probably more important for recurrence than the molecular features of a resected tumor. Urinary markers have very limited value in prognostication of bladder cancer and are used (mainly as an adjunct to cytology) for detection and surveillance of urothelial cell cancer recurrence. Prediction of progression with molecular markers holds considerable promise. Nevertheless, the contemporary value of molecular markers over clinico-pathologic indexes is limited.

Local recurrence after radical nephroureterectomy (RNU) owing to urothelial carcinoma of the upper urinary tract is rare. The usual treatment is systemic chemotherapy followed by optional resection of the mass. We introduce the case of a 73-year-old male patient with multiple comorbidities in whom retroperitoneal carcinoma recurrence of 31 mm was diagnosed via positron emission tomography-computed tomography scan with 18-fluorodeoxyglucose about 5 years after he had undergone RNU owing to urothelial carcinoma of the upper urinary tract. The patient was treated with computed tomography-guided percutaneous radiofrequency ablation. Later scans with contrast controls showed lack of contrast uptake and a decrease of the lesion's size. Twenty-four months after the procedure, the patient is free of the disease. To date, this is the first case of recurrence of urothelial carcinoma that was treated with percutaneous radiofrequency ablation, thus establishing an alternative to chemotherapy in patients with substantial comorbidities.

OBJECTIVETo study the clinicopathologic features and prognosis of plasmacytoid urothelial carcinoma (PUC) of the urinary bladder.

METHODSThe clinical and pathologic findings of 16 cases of PUC were retrospectively reviewed. Immunohistochemical study (MaxVision method) was carried out. The follow-up data were analyzed.

RESULTSThere were altogether 15 males and 1 female. The age of patients ranged from 40 years to 85 years (median = 64 years). Most patients (15/16) presented with hematuria. The tumor cells were small to medium in size and contained eccentric nuclei and moderate to abundant eosinophilic cytoplasm, assuming a plasmacytoid appearance. The architectural pattern varied from loosely cohesive sheets to cords, papillae, small nests or gland-like structures. Most tumors invaded into the lamina propria or muscularis propria. Twelve of the 16 cases had concurrent conventional urothelial carcinoma component. Immunohistochemical study showed that the tumor cells in all cases were strongly positive for AE1/AE3, epithelial membrane antigen, CK7 and CK18. CK20 and uroplakin III were also expressed in 9 cases. CEA, p53, CD138, p63 and E-cadherin were positive in 12, 13, 15, 11 and 10 cases, respectively. Ki-67 index ranged from 5% to 70% (mean = 30%). All tumors were negative for vimentin, LCA, kappa/lambda light chains, S-100 protein, HMB 45,Melan A, smooth muscle actin and desmin. Follow-up information was available in 13 patients. The duration of follow up ranged from 3 months to 10 years. Three patients died of distant metastasis at 3, 27 and 60 months after the operation, respectively. One patient was alive with disease at 25 months. One was alive at 43 months with a prior recurrence. Another 8 patients were alive and disease free at 7 to 120 months.

CONCLUSIONSPUC of the urinary bladder is a rare variant of high-grade urothelial carcinoma. Immunohistochemical study with positivity for CK7, CK20, p63 and uroplakin III and negative staining for vimentin and LCA may be helpful in the differential diagnosis. PUC is a malignant tumor with high invasiveness, high recurrence rate and poor prognosis. Radical cystectomy is considered as the first line treatment for PUC.

OBJECTIVETo study the clinicopathologic features of urothelial hyperplastic lesion with an endophytic growth pattern and the role of immunohistochemistry and multitargeted fluorescence in situ hybridization (FISH) in the differential diagnosis.

METHODSForty-one cases of urothelial lesions exhibiting endophytic growth patterns were reviewed and reclassified as inverted papilloma, urothelial carcinoma with an endophytic growth pattern, and florid von Brunn nest. The gains of chromosomes 3, 7, and 17 and loss of 9p21 was detected by FISH, and performed immunohistochemical staining for CK20, p53, and Ki-67. Follow-up data of 12 cases were obtained.

RESULTS(1) Twelve inverted papillomas sized 1.2 cm in average, consisted of anastomosing cords and nests with uniform width distribution involving the lamina propria, the central portion contained streaming cells with squamous metaplasia, and the periphery showed palisading. No or rare atypia and mitosis were found. Focal exophytic papillary component lined by less than 6 layers of normal urothelium were observed in 4 cases. (2) Twenty-four urothelial carcinomas with an endophytic growth pattern sized 2.1 cm in average, demonstrated the similar architecture with inverted papilloma, but exhibited thick columns and variable thickness of the cords, irregular size and shape of large nests with transition into solids. Mild to moderate cytologic atypia was shown, and mitotic figures ranged 1 to 8 per 10 HPFs. Exophytic papillary component was not observed in 3 cases, but the superficial urothelium showed dysplasia, while coexisted exophytic component in other cases was associated with low malignant potential or low grade tumor. (3) Five florid von Brunn nests sized 0.9 cm in average, had normal or hyperplastic urothelium, variable nests with cysts compacted in lamina propria, no cytologic atypia and mitosis. Twenty-one of 24 (79.1%) urothelial carcinomas with an endophytic growth pattern displayed abnormally positive results by multitargeted FISH, whereas all inverted papillomas and florid von Brunn nests were negative. Immunohistochemically, CK20 was weakly positive in 2 cases of urothelial carcinoma with an endophytic growth pattern, and negative in all inverted papillomas and florid von Brunn nests. p53 weakly stained 5% to 50% nuclei of the tumor cells in 16 cases of urothelial carcinomas with an endophytic growth pattern and 1 inverted papilloma. 1%-5% tumor cells expressed Ki-67 in urothelial carcinoma with an endophytic growth pattern, and less than 1% in inverted papilloma and florid von Brunn nests. Follow-up study revealed that 2 cases of urothelial carcinoma with an endophytic growth pattern had developed invasive carcinoma, underwent cystectomy, and metastasized remotely. No recurrence occurred in cases of inverted papilloma.

CONCLUSIONSBenign and malignant urothelial lesions with an endophytic growth pattern present histologic overlapping. Urothelial carcinoma with an endophytic growth pattern displays unique characteristics in morphology and immunohistochemistry. Multitargeted FISH analysis is helpful in the differential diagnosis.

We examined whether the presence and severity of preoperative hydronephrosis have prognostic significance in patients who underwent radical cystectomy for transitional cell carcinoma of the bladder. The medical records of 457 patients who underwent radical cystectomy for bladder cancer between 1986 and 2005 were retrospectively reviewed. Following the Society for Fetal Urology grading system, patients were divided into low-, and high-grade hydronephrosis groups. Clinicopathologic factors associated with preoperative hydronephrosis and survival were evaluated. Of a total of 406 patients, unilateral hydronephrosis was found in 74 (18.2%), bilateral hydronephrosis in 11 (2.7%), and no hydronephoris in 321 (79.1%). Low-grade hydronephrosis was found in 57 (12.2%) patients and high-grade hydronephrosis in 28 (6%). Preoperative hydronephrosis was related to higher pT stage and lymph node invasion. In univariate analysis, the presence of hydronephrosis, hydronephrosis grade, age, pT and pN stage, tumor grade, surgical margin, number of retrieved nodes, carcinoma in situ, and lymphovascular invasion were significant prognostic factors for cancer-specific survival. In multivariate analysis, bilateral hydronephrosis and high-grade hydronephrosis remained significant predictors for decreased survival. The presence of preoperative hydronephrosis, and high-grade hydronephrosis are significant prognostic factors in patients with bladder cancer after radical cystectomy.

OBJECTIVETo improve the diagnosis and treatment of coincident vesical transitional cell carcinoma (VTCC) and prostate cancer.

METHODSWe analyzed the clinical data of 5 cases of coincident VTCC and prostate cancer.

RESULTSThe 5 patients, at the mean age of 66.2 years, were diagnosed as having grade II - III VTCC by cystoscopy and biopsy, 1 with a history of prostate cancer, and the other 4 with prostate cancer confirmed by postoperative pathological examination. Two of the patients were treated by radical cystoprostatectomy, 1 by radical cystoprostatectomy and ileum conduit surgery, 1 by transurethral resection of bladder tumor, and the other 1 by palliative ureterocutaneostomy due to cardiopulmonary problems. The follow-up lasted 8 -26 months. One of them died of diffused metastasis 20 months after surgery, 1 survived with the tumor untreated, and the other 3 remained tumor free.

CONCLUSIONCoincident VTCC and prostate cancer is easy to be missed in diagnosis. PSA detection, rectal palpation, transrectal ultrasonography, biopsy, and cystoscopy are the main diagnostic options for this disease. Its treatment should be based on the classification and clinical staging of the two cancers. Coincident VTCC and prostate cancer does not suggest poor prognosis.

OBJECTIVETo evaluate the expression and clinical significance of urinary nuclear matrix protein (NMP22) and cytokeratin 18 (CK18) for transitional cell carcinoma of the bladder.

METHODSUrinary NMP22 and CK18 levels of 293 patients with transitional cell carcinoma of the bladder, 400 patients with non-transitional cell carcinoma of the bladder, and 105 bladder benign disease were analysed by enzyme-linked-immunosorbent assay (ELISA).

RESULTSThe levels of urinary NMP22 and CK18 in the patients with transitional cell carcinoma of the bladder (M = 17.3 U/ml, M(CK18) = 484.2 U/L) were significantly higher than those in the non-transitional cell carcinoma of the bladder (M = 6.8 U/ml, M(CK18) = 156.0 U/L) and the benign disease group (M(NMP22) = 2.3 U/ml, M(CK18) = 66.6 U/L) (P < 0.001). The sensitivity and specificity of urinary NMP22 and CK18 were 79.2%, 88.6% and 78.2%, 82.9%, respectively, for transitional cell carcinoma of the bladder before any treatment. The joint sensitivity of the two markers was 91.7%. The NMP22 and CK18 levels were significantly lower in the recovered patients after surgical operation (P < 0.01), while in patients with recurrence or metastasis the levels of the markers were significantly higher (P < 0.01). There was a significant relationship between NMP22 and CK18, (r = 0.689, P < 0.01). The levels of urinary nmp22 and CK18 were significantly different among pathological grade G1, G2, G3, and stage Ta, T1, T2, T3 (P < 0.01).

CONCLUSIONNMP22 and CK18 are useful tumor marker for diagnosis of transitional cell carcinoma of the bladder and for monitoring the state of illness. The joint use of the two markers can improve the sensitivity of cancer detection. NMP22 and CK18 may become a new class of tumor markers, and to be the basis for development of a new assay with an increased efficacy for the detection and treatment of bladder cancer.
