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.

A 70-yr-old man presented with painless gross hematuria. He underwent right nephrectomy for benign disease 9 yr ago. Computed tomography and cystoscopy showed a mass in the distal region of the right ureteral stump. He underwent right ureterectomy and bladder cuff resection. Pathological examination showed T1 and WHO grade 2 transitional cell carcinoma. At 6 months postoperatively, the patient is alive without any evidence of recurrence.

4.New and contemporary markers of prognosis in nonmuscle invasive urothelial cancer.
Korean Journal of Urology 2015;56(8):553-564
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.

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.

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 and biologic behavior of renal cell carcinoma (RCC) with rhabdoid features.
METHODSTen cases of RCC with rhabdoid features collected during the period from 1995 to 2005 were enrolled into the study. The clinical findings were analyzed and the hematoxylin and eosin-stained sections were reviewed. Immunohistochemistry and electron microscopy were also performed.
RESULTSThe age of patients ranged from 33 to 69 years (mean age = 52 years). Nine of the patients were males and 1 female. Five patients showed evidence of perinephric invasion. Two patients presented with regional lymph node metastases and 1 patient showed distant metastasis to the lung. Histologically, the rhabdoid foci were characterized by loosely cohesive trabeculae, acini, lobules and clusters of rhabdoid cells in otherwise clear cell RCC (9 cases) or papillary RCC (1 case). The rhabdoid cells were round to polygonal in shape and contained globular eosinophilic inclusion bodies in the cytoplasm, eccentric nuclei, vesicular chromatin pattern and prominent nucleoli. Coagulative tumor necrosis was commonly seen. Immunohistochemical study showed that the rhabdoid cells were diffusely positive for CD10 (10/10), cytokeratin AE1/AE3 (10/10), epithelial membrane antigen (10/10) and vimentin (10/10). Focal staining for neuron-specific enolase and S-100 protein was also noted. They were negative for CK7, CK20 and myogenic markers (including myogenin, smooth muscle actin and muscle-specific actin). The mean Ki-67 labeling index of the rhabdoid component was higher than that of the non-rhabdoid component (P < 0.05). Follow-up information was available in 8 patients. While 6 patients are still alive without recurrence, 2 patients died of the disease 6 and 29 months respectively after the operation.
CONCLUSIONSRCC with rhabdoid elements are mainly observed in clear cell RCC and need to be distinguished from oncocytic renal tumors and malignant rhabdoid tumor of kidney. The higher proliferative activity in the rhabdoid areas may indicate more aggressive biologic behavior.

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.
