The aim of this study was to evaluate our experience using radical cystectomy to treat patients with bladder cancer and to describe the associations between pathologic features and clinical outcomes. All 701 patients who underwent radical cystectomy for bladder cancer were evaluated. The patient population consisted of 623 men and 78 women. The overall 5 and 10 yr recurrence-free survival (RFS) rates were 61.8% and 57.7%, respectively, and the 5 and 10 yr cancer-specific survival (CSS) rates were 70.8% and 65.1%, respectively. Multivariate analysis showed that factors significantly predictive of RFS and CSS included extravesical extension (P = 0.001), lymph node metastasis (P = 0.001), and lymphovascular invasion (P < 0.001 and P = 0.007). The 5 and 10 yr RFS rates for patients with lymph node metastasis were 25.6% and 20.8%, respectively, and the 5 and 10 yr CSS rates were 38.6% and 30.9%, respectively. Adjuvant chemotherapy significantly improved RFS (P = 0.002) and CSS (P = 0.001) in patients with lymph node metastasis. Radical cystectomy provides good survival results in patients with invasive bladder cancer. Pathologic features significantly associated with prognosis include extravesical extension, node metastasis, and lymphovascular invasion. Adjuvant chemotherapy improves survival in patients with advanced stage disease.

OBJECTIVETo study the clinical and pathologic characteristics of small cell neuroendocrine carcinoma of urinary tract.
METHODSAll cases of urinary tract carcinoma encountered in the General Hospital of People Liberation Army during the period from 1999 to 2010 were retrospectively reviewed. The clinicopathologic data of small cell neuroendocrine carcinomas were further analyzed, with literature review.
RESULTSA total of 16 cases of small cell neuroendocrine carcinoma were identified, including 10 from urinary bladder, 2 from ureter, 3 from renal pelvis, and 1 multifocal tumor involving renal pelvis and ureter. There were altogether 8 males and 8 females. The median age of the patients was 63 years (range = 24 to 79 years). Gross hematuria (11 cases) represented the main presenting symptom. Four patients had flank pain and 4 had urinary irritation symptoms. Seven patients underwent radical cystectomy. Six other patients underwent radical nephroureterectomy, 1 partial cystectomy, 1 TURBT and the remaining case biopsy only. The size of the tumor ranged from 0.8 to 8.0 cm (median = 4.5 cm). Histologically, 15 cases represented mixed small cell neuroendocrine carcinoma (with 13 mixed with transitional cell carcinoma and 2 with adenocarcinoma). Immunohistochemical study showed positive staining for neuroendocrine markers. On presentation, 1 patient was in stage pT1, 7 in stage pT2, 6 in stage pT3, 2 in stage pT4. Six patients died of the disease after operation. The overall survival was 25 months and the 5-year survival rate was 32.4%.
CONCLUSIONSSmall cell neuroendocrine carcinoma of urinary bladder is a highly malignant disease and associated with poor prognosis. The diagnosis relies on detailed histologic examination. Early diagnosis, when coupled with cystectomy or nephroureterectomy and adjuvant chemotherapy, represents the mainstay of management.

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 evaluate the apoptosis-inducing effect of intravesical instillation of pirarubicin (THP) on bladder cancer and normal bladder tissue, and explore the mechanism of such treatment for preventing recurrence of non-muscle invasive bladder cancer.
METHODSForty patients with primary non-muscle invasive bladder cancer were treated in our hospital from January 2006 to October 2008. The patients were divided into three groups, including 15 cases treated by intravesical instillation of THP (30 mg/50 ml, 0.5 hours) at 1 hour, 15 cases at 24 hours before transuretheral resection of bladder tumor (TUR-BT), and 10 cases in control group who received TUR-BT only. The THP uptake of the tumor and normal bladder tissues was observed by fluorescence microscopy, the apoptosis was assessed with TUNEL staining, and immunohistochemistry was used to detect the expression of bcl-2 and bax.
RESULTSSeldom fluorescence of THP in normal bladder tissues and some diffuse fluorescence reaching the muscular layer in the tumor area were observed after THP instillation at 1 hour before TUR-BT. The fluorescence of THP could still be observed in the tumor tissues at 24 hours after THP instillation. The apoptosis indexes (AI) of tumors in the chemotherapy groups were significantly higher than that in the control group (P < 0.01). There was a correlation between bcl-2/bax ratio and AI.
CONCLUSIONPirarubicin can be uptaken by bladder cancer tissue selectively and induces apoptosis of tumor cells. The changes of expression of bcl-2 and bax and decreasing of the bcl-2/bax ratio may be an important mechanism of action of the intravesical instillation of THP for preventing recurrence of non-muscle invasive bladder cancer.

The objective of this study was to evaluate the risk of recurrence in patients with intermediate-risk non-muscle-invasive bladder cancer (NMIBC) after intravesical instillation with chemotherapeutic agents or Bacillus Calmette-Guerin (BCG) therapy. A cohort of 746 patients with intermediate-risk NMIBC comprised the study group. The primary outcome was time to first recurrence. The recurrence rates of the transurethral resection (TUR) alone, chemotherapy, and BCG groups were determined using Kaplan-Meier analysis. Risk factors for recurrence were identified using Cox regression analysis. In total, 507 patients (68.1%), 78 patients (10.5%), and 160 (21.4%) underwent TUR, TUR+BCG, or TUR+chemotherapy, respectively. After a median follow-up period of 51.7 months (interquartile range=33.1-77.8 months), 286 patients (38.5%) developed tumor recurrence. The 5-yr recurrence rates for the TUR, chemotherapy, and BCG groups were 53.6%+/-2.7%, 30.8%+/-5.7%, and 33.6%+/-4.7%, respectively (P<0.001). Chemotherapy and BCG treatment were found to be predictors of reduced recurrence. Cox-regression analysis showed that TUR+BCG did not differ from TUR+chemotherapy in terms of recurrence risk. Adjuvant intravesical instillation is an effective prophylactic that prevents tumor recurrence in intermediate-risk NMIBC patients following TUR. In addition, both chemotherapeutic agents and BCG demonstrate comparable efficacies for preventing recurrence.

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.
METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.
RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).
CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

Few large scale studies have reported the oncologic outcome of radical cystectomy for treating bladder cancer in China; hence, we lack long-term prognostic information. The aim of the current study was to determine the survival rate and prognostic factors of patients who underwent radical cystectomy for bladder cancer in a Chinese medical center. We retrospectively analyzed clinicopathologic data from 271 bladder cancer patients who underwent radical cystectomy between 2000 and 2011. Univariate and multivariate analyses were conducted to identify independent prognostic predictors for this cohort. Median follow-up was 31.7 months (range, 0.2-139.1 months). Thirty-day mortality was (1.4%). The 5-year recurrence-free survival, cancer-specific survival (CSS), and overall survival rates were 61.6%, 72.9%, and 68.0%, respectively. The 5-year CSS rates of patients with T1-T4 disease were 90.7%, 85.0%, 51.0%, and 18.0%, respectively. Patients with organ-confined disease had a higher 5-year CSS rate than those with extravesical disease (81.4% vs. 34.9%, P < 0.001). For the 38 patients (14%) with lymph node involvement, the 5-year CSS rate was 27.7%-significantly lower than that of patients without lymph node metastasis (P < 0.001). The 5-year CSS rate was much higher in patients with low grade tumor than in those with high grade tumor (98.1% vs. 68.1%, P < 0.001). Multivariate Cox regression showed that patient age (hazard ratio, 2.045; P = 0.013) and T category (hazard ratio, 2.213; P < 0.001) were independent predictors for CSS. These results suggest that radical cystectomy is a safe and effective method for treating bladder cancer in Chinese patients. Old age and high T category were associated with poor prognosis in bladder cancer patients who underwent radical cystectomy.
