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.

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.

OBJECTIVETo summarize the experience in the diagnosis and treatment of non-epithelial tissue tumor of urinary bladder.

METHODS>From 1953 to April 2002, a total of 28 patients with non-epithelial tissue tumor in 3 925 bladder tumor cases were analyzed.

RESULTSPainless gross hematuria, pelvic mass, urinary frequency and dysuria are symptoms of non-epithelial bladder tumor. Ultrasonic examination, computed tomography (CT) scan, cystoscopy and biopsy is used for diagnosis of the tumor. Seventeen of 28 patients (61.7%) were malignant neoplasms in 7 kinds of pathologic types, which was small cell carcinoma (5 cases), rhabdomyosarcoma (4 cases), leiomyosarcoma (4 cases), lymphoma (1 case), malignant fibrous histiocytoma (1 case), liposarcoma(1 case), melanoma (1 case) respectively. Eleven of 28 patients (39.3%) were benign tumors with 4 kinds of histologic types including 2 cases of cavernous hemangioma, 1 case of fibroma, 1 case of leiomyoma, 7 cases of pheochromocytoma. All benign tumor patients were treated with partial cystectomy, transurethral bladder tumor resect (TURBT) and fulguration. In 17 malignant neoplasms patients, 7 of them received partial cystectomy, 9 received radical cystectomy, and 1 patient's tumor was unresectable. Those malignant bladder tumor patient are followed up, but 3 years survival rates is only 8/17.

CONCLUSIONSNon-epithelial tissue tumor of the urinary bladder is rare with complicated pathologic types. Malignant neoplasms are more than benign tumors with very poor prognosis, benign tumors' prognosis is good. Diagnosis rate which was confirmed before operation is low. Dip biopsy under cystoscopy may enhance the diagnosis rate. Surgical treatment is the main therapy for non-epithelial tissue tumor of the urinary bladder. Because of the aggressive biologic behavior of malignant tumors, they should be identified promptly and treated appropriately. According to the histologic appearance radiotherapy and chemotherapy is mandatory in some cases.

Bladder cancer remains a commonly diagnosed malignancy worldwide, bringing huge economic burden and high morbidity for patients. Assessment of prognostic significance of lymphovascular invasion (LVI) is a critical issue in the surgical management of bladder cancer after transurethral resection or radical cystectomy. A systematic search of PubMed, Embase and Cochrane Library was performed up to Oct 10, 2014 to identify eligible studies. Outcomes of interest were collected from studies comparing overall survival (OS), cancer specific survival (CSS) and recurrence free survival (RFS) in patients with the LVI. Results of studies were pooled, and combined hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) for survival were used as the effect size estimation. Funnel plots were done to show the publication bias, while the forest plots and subgroup analyses were used to limit the heterogeneity. A total of 20 studies (10 663 patients) met the eligibility criteria and were included for this meta-analysis. Our pooled results showed that there were significant differences in OS (pooled HR, 1.71; 95%CI, 1.52-1.92; P<0.00001), CSS (pooled HR, 2.25; 95% CI, 1.80-2.81; P<0.00001) and RFS (pooled HR, 1.91; 95% CI, 1.57-2.32; P<0.00001) between the patients with LVI and the patients without LVI. There were significant heterogeneities observed in the studies concerning the relationship between LVI and CSS, RFS. There was no clear evidence of publication bias. When tumor stage was beyond T3, LVI lost its predictive value for CSS and RFS. For the patients who had negative lymph nodes, LVI was still an adverse predictor. Our pooled results demonstrate that LVI indicates poor prognosis of patients with bladder cancer after surgical procedures, and it can be of particular importance in clinical practice. However, these results need to be further confirmed by more adequately designed prospective studies.

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.

A 78-yr-old woman presented with gross hematuria for 2 weeks. On cystoscopy, a frond-like mass was observed at the bladder trigone. Transurethral resection of bladder tumor was performed for the mass. Histopathological findings showed that 90% of lesions were lymphoepithelioma-like carcinoma (LELCA) and a few lesions were non-invasive transitional cell carcinoma. On microscopy, syncytial growth pattern and indistinct cytoplasmic borders were observed with the severe infiltration of lymphoid cells. The case was followed-up for 8 months without recurrence. This is the first report of a LELCA case in Korea.

INTRODUCTIONBladder cancer is a common malignancy but presentation with metastatic disease is rare. This is the fi rst reported case of duodenal obstruction as a presentation of metastatic bladder cancer.

CLINICAL PICTUREA middle-aged woman presented with nausea, vomiting, weight loss and intermittent haematuria. Radiology and histology confirmed metastatic bladder cancer to the retroperitoneum encasing the duodenum and causing obstruction.

TREATMENTInsertion of a duodenal stent relieved the obstruction and palliative chemoradiotherapy was initiated.

OUTCOMEThe patient died 15 months after diagnosis.

CONCLUSIONSClinicians and radiologists should be aware of atypical presentations of common malignancies.

OBJECTIVETo study the clinicopathologic features, diagnosis and differential diagnosis of inflammatory myofibroblastic tumor of the urinary bladder.

METHODSExcisional specimens from 5 cases of vesical inflammatory myofibroblastic tumor were studied by light microscopy and immunohistochemistry (EnVision). The clinical data were also analyzed.

RESULTSAmong the 5 patients studied, 3 were males and 2 were females. The age of the patients ranged from 10 to 53 years (mean age = 35 years). The most common clinical presentation was micturition pain and hematuria. Three cases were located at the dome of the urinary bladder and the remaining 2 cases were found in the left lateral wall. Histologically, the tumor varied from myxoid to highly cellular. The tumor cells were spindle to stellate in shape, widely separated or showed a compact fascicular pattern. There were often associated with mixed inflammatory infiltrates and an irregular meshwork of small dilated vessels. Immunohistochemical study showed that the tumor cells expressed AE1/AE3 (5/5), vimentin (5/5), smooth muscle actin (5/5), calponin (5/5), caldesmon (3/5), desmin (4/5) and anaplastic lymphoma kinase protein (4/5). Follow-up data were available in 4 patients and none had local recurrence or died of this disease.

CONCLUSIONInflammatory myofibroblastic tumour of urinary bladder is a rarely encountered but distinctive neoplasm with intermediate malignant potential.
