The role of bcl-2, p53, and ki-67 index in predicting tumor recurrence for low grade superficial transitional cell bladder carcinoma

PURPOSE: We assess the prognostic significance of bcl-2 expression, p53 mutation and ki-67 index for low grade, superficial transitional cell bladder carcinoma. MATERIALS AND METHODS: The medical records of 93 cases of primary, low grade (24 G1, 69 G2), superficial (70 pTa, 23 pT1) transitional cell carcinoma of the bladder were reviewed. Association of bcl-2, p53 and ki-67 index immunoreactivity with tumor grade and stage was examined. Prognostic significance of tumor grade, pathological stage, bcl-2 expression, p53 mutation and ki-67 index in predicting tumor recurrence was assessed. RESULTS: Of the tumors 60 (70%) had p53 mutation and 9 (10.5%) expressed bcl-2. These 2 markers did not relate to tumor grade or pathological stage. Median ki-67 index was 10.9% and positively correlated with tumor grade. Recurrence was noted in 34.9% of patients with a median followup of 26 months (range 1 to 84). The ki-67 index was the only significant prognostic indicator in univariate and multivariate analyses. This marker can further distinguish grade 2 tumors with a favorable prognosis from those with an unfavorable outcome. CONCLUSIONS: The ki-67 labeling index is an independent predictor of tumor recurrence for patients with primary superficial, low grade bladder cancers.

Fascin is a predictor for invasiveness and recurrence of urothelial carcinoma of bladder

ObjectivesTo evaluate the expression of fascin in bladder urothelial carcinoma, and to analyze its association with clinicopathologic features and prognosis of urinary bladder urothelial carcinoma.Materials and methodsImmunohistochemistry was used to detect the expression of fascin, Ki-67, p53, CK20, and multidrug resistance gene (MDR) in 111 bladder urothelial carcinoma and 42 normal epithelial tissues. The association between fascin expression and clinicopathologic parameters and prognostic factors on tumor recurrence was analyzed by Kaplan-Meier method, log-rank test, and Cox proportional hazards model.ResultsNinety-four of 111 cases of bladder urothelial carcinoma showed positive fascin expression, while no fascin expression was detected in normal transitional epithelium. There was a significant difference in the expression of fascin in normal epithelium and bladder urothelial carcinoma (P = 0.000). Fascin expression was positively correlated with pT stage (P = 0.001) and tumor size (P = 0.011), while it had no association with age, gender, and tumor grade (P > 0.05). pT stage and the expression of fascin, Ki-67, p53, and CK20 were significantly correlated with urothelial carcinoma recurrence, and fascin expression was an independent factor predicting tumor recurrence.ConclusionsFascin expression was up-regulated in bladder urothelial carcinoma. Over-expression of fascin might play an important role in invasiveness and recurrence of bladder urothelial carcinoma. Fascin may be used as a prognostic marker and a new target for the treatment of bladder urothelial carcinoma.

p130Cas,E‐cadherin and β‐catenin in human transitional cell carcinoma of the bladder: Expression and clinicopathological significance

Objectives: To investigate the effects of junction protein, p130 Crk‐associated substance (p130Cas), and adhesion molecules, E‐cadherin and β‐catenin, on the biological behavior of transitional cell carcinoma of the bladder. Methods: In 72 paraffin embedded specimens of transitional cell carcinoma of the bladder and 20 normal controls, the expression of p130Cas, E‐cadherin and β‐catenin was examined by quantum dot‐based immunofluorescence histochemistry (QD‐IHC) and conventional immunohistochemistry (IHC). Results: QD‐IHC was consistent with IHC in detecting the expression of the three molecules (P > 0.05 for all comparisons). The positive expression rate of p130Cas in bladder cancer tissues increased more significantly than that in normal bladder tissues (P < 0.001). Similarly, the aberrant expression rates of E‐cadherin and β‐catenin in bladder cancer tissues were significantly higher than those in normal bladder tissues (P < 0.001 for both comparisons). The expression of each molecule was correlated with tumor pathological grade and clinical stage (P < 0.05 for all comparisons), but not with tumor number and size (P > 0.05 for all comparisons). Furthermore, negative correlations were found between the expression intensities of p130Cas and E‐cadherin or β‐catenin in transitional cell carcinoma of the bladder (P < 0.05 for both comparisons). Conclusions: p130Cas, E‐cadherin and β‐catenin might represent useful predictors of malignant degree of transitional cell carcinoma of the bladder.

Expression of pS2 protein and its relation with the Ki-67 proliferative indices and tumor recurrence in superficial bladder carcinomas

OBJECTIVE: To investigate the expression and possible role of pS2 protein as a predictor of tumor recurrence in superficial transitional cell carcinoma of the bladder and to determine its relation with tumor stage, grade, size, number, recurrence and proliferative activity. METHODS: Paraffin sections of transurethral resection material from 80 patients with superficial transitional cell bladder carcinoma were stained with pS2 and Ki-67 antibodies using the standard streptavidin biotin immunoperoxidase method. Cytoplasmic pS2 staining was scored on a scale of 1-3 and the Ki-67-labelling index was determined as a percentage of positively staining tumor cells. RESULTS: An inverse relationship was found between pS2 expression and Ki-67 index (p<0.001). pS2 expression showed no relation with any clinicopathological prognostic parameters as well as the recurrence rate. The recurrence rate was only associated with increased tumor number (p = 0.05), while the time to first recurrence was significantly related to tumor size, proliferative activity and tumor grade (p = 0.04, p<0.001, and p = 0.03, respectively). On the other hand, higher tumor grade was correlated with increased tumor number, Ki-67 index and tumor stage (p = 0.016, p = 0.006, and p<0.001, respectively). CONCLUSION: pS2 expression is associated with a low proliferative potential of superficial transitional cell carcinoma of the bladder, while it does not seem to be related to the recurrence rate of the tumor and other prognostic factors. Tumor size and proliferative activity may aid in the estimation of the time to the first recurrence.     

Prognostic factors for survival and bladder recurrence in transitional cell carcinoma of the upper urinary tract

BACKGROUND: Prognostic factors for survival in transitional cell carcinoma of the upper urinary tract have been extensively evaluated, but detailed analyses of patterns of bladder recurrence after surgery have been rare. METHODS: The outcome and tumor recurrence of 93 patients with transitional cell carcinoma of the upper urinary tract surgically treated between 1975 and 1999 were reviewed, retrospectively. Disease-specific survival by pathologic stage and grade were analyzed by the Kaplan-Meier METHOD: Prognostic factors for survival and bladder recurrence were examined by univariate and multivariate analysis. RESULTS: The 5-year disease-specific survival rates of the patients with pTa, T1 and T2 were 92.9%, 100% and 88.9%, respectively. However, that of the pT3 patients was 61.9% and the median survival of the pT4 cases was only 7 months. Bladder recurrence was seen in 40 cases and recurrences occurred within 1 year in 32 of these patients. The stage and grade of metachronous bladder tumors usually resembled those of primary tumors, but invasive recurrences were seen in 19% of recurrent cases with primary pTa, pT1 tumors. The significant prognostic factor for survival was pathologic stage (pT3, pT4), but no significant variables were detected for bladder recurrence by multivariate analysis. CONCLUSIONS: The prognosis of pT3, pT4 patients is poor and effective systemic adjuvant therapy is necessary. Invasive bladder recurrence occurred in 19% of patients with superficial primary tumors. As no significant prognostic variables for bladder recurrence were identified, careful follow up for bladder recurrence is important even if the primary tumors are non-invasive.     

Evaluation of p53 nuclear accumulation in low- and high-grade (WHO/ISUP classification) transitional papillary carcinomas of the bladder for tumor recurrence and progression

OBJECTIVES: To evaluate the association of p53 nuclear accumulation with recurrence and progression in transitional cell carcinomas of the bladder and to examine the distribution of p53 in low-grade and high-grade transitional cell carcinomas according to the World Health Organization/International Society of Urological Pathology classification. PATIENTS AND METHODS: Nuclear accumulations of p53 were examined in a total of 99 patients with transitional cell carcinoma between May 1995 and October 1999. The mean age was 64 years. There were 94 (95%) men and 5 (5%) women. Following resection, surgical specimens were examined, and p53 accumulation with a 20% cutoff value was accepted as positive staining. Of the 99 patients, 52 (53%) had histologically superficial bladder tumors, and 47 (47%) had invasive tumors. Data concerning grade, stage, number of recurrences, and disease progression were available for each patient. RESULTS: The median follow-up period was 55 months. 60 of the 99 patients (61%) had p53 overexpression. The difference for p53 overexpression between low-grade and high-grade tumors was significant (p < 0.05). In low- and high-grade tumors, there was no significant relationship for recurrence between p53-positive and p53-negative groups. But there was a statistically significant relationship between progression and histological grade of the tumors. p53 had no significant relationship with tumor recurrences (p > 0.05), but its relationship with progression was statistically significant (p < 0.05). CONCLUSIONS: We did not find a correlation between tumor recurrence and p53 overexpression, but p53 overexpression has a predictive value in determining tumor progression. High-grade tumors had higher p53-positive values than low-grade tumors. This group of patients should be considered for radical therapies on the basis of other prognostic parameters.
