Blood group antigen (BGA) expression was studied on frozen sections from the initial, presenting, transitional cell bladder cancers of 73 patients. Clinical follow-up was prospective and, after 3 years, 59 patients were available for assessment. Of 32 tumours that retained substantial BGA (BGA+ and BGA +/- ), 11 progressed. Of 27 tumours with less than 5% or undetectable BGA expression (BGA-), 14 did not progress. Of 24 pTa tumours, 17 had substantial BGA expression and 7 were BGA-; 5 patients progressed, 4 substantially BGA positive and 1 BGA-, all to category pT1; 15 tumours were category pT1, 7 substantially BGA positive and 8 BGA-; 7 patients progressed, 1 substantially BGA positive and 6 BGA-, all of whom died from bladder cancer; 20 were pT2 or deeper, 8 substantially BGA positive and 12 BGA-; 12 patients progressed, 6 substantially BGA positive and 6 BGA-, all of whom died from bladder cancer. Despite improved understanding of the biochemistry and techniques of detection of BGA, these results preclude the use of BGA determination as a guide to prognosis in individual transitional cell carcinoma, whether used alone or in combination with pT category.

Two cases of bladder carcinoma are described. The patients were of similar age, were both smokers and were treated for the same period, but exhibited completely different later clinical courses. Initially, both had a single, papillary, pedunculate tumor, identified as a transitional cell carcinoma, grade 2, pTa. One patient, six years later, had multiple papillary tumors covering almost all the mucosal surface and underwent simple cystectomy. Histologically the tumors were identified as transitional cell carcinomas, grade 2, pT1. The other patient, nine years later, had a single nodular invasive tumor with a concomitant, very tiny papillary tumor and underwent radical cystectomy. Histologically the tumor was transitional cell carcinoma, grade 2 greater than 3, pT4. Many of the questions raised by these cases are unanswered, but comparison of such cases should provide some clues to the natural history of bladder carcinoma.

Total cystectomy was performed on 95 patients with primary urinary bladder cancer between 1973 and 1983. Histopathological and prognostic studies were reviewed according to the general rules for clinical and pathological studies on bladder cancer. The cancer histological type were transitional cell carcinoma in 87 cases, squamous cell carcinoma in 5 cases, adenocarcinoma in 2 cases, and undifferentiated carcinoma in 1 case. The overall 5-year actuarial survival rate was 36.0%. As for the growth pattern of the bladder cancer, the 5-year survival rates for the patients with papillary non-invasive type (PNT), papillary invasive type (PIT), and non-papillary invasive type (NIT) were 100%, 25.8% and 34.8% respectively. As for the stage, the 5-year survival rates for the patients with pTa, pT1, pT2, pT3a, pT3b, and pT4 were 81.8%, 64.7%, 40.1%, 30.5%, 22.6% and 6.7% respectively. Of 87 patients with transitional cell carcinoma, the 5-year survival rates for the patients with grade 1, grade 2 and grade 3 were 100%, 43.0% and 32.1% respectively. Intramural lymphatic invasion and vascular invasion and intramural histopathological mode of spread were significant indicators of prognosis.

A Tegafur suppository of 750 mg was administered daily to 20 patients with bladder tumors, whose ages ranged from 43 to 84 years (average age 63.7). Histological study revealed transitional cell papilloma in 6 cases, transitional cell carcinoma in 12 cases, squamous cell carcinoma in 1 case and malignant tumor with extensive necrosis in 1 case. The result of staging and grading was as follows: 8 cases of pTa, 5 cases of pT1, 9 cases of pT2, 1 case of pT3a, 2 cases of pT3b and 1 case of T4; an, 6 cases of G0, 6 cases of G1, 5 cases of G2, 2 cases of G3 and 1 case of unknown grade. According to Saitoh and Koyama's criteria, no cases showed complete response (0%), 5 cases partial response (25%), 3 cases minor response (15%), 10 cases no change (50%) and 2 cases progressive disease, making the total effective rate 25.0%. Some side effects were observed in 6 of the cases (30%): General malaise in 4 cases (20%), loss of appetite in 3 cases (15%), diarrhea in 1 case (5%), edema in 1 case (5%), anemia in 2 cases (10%), an elevation of both GOT and GPT in 1 case (5%) and thrombocytopenia in 1 case (5%). A recovery from these side effects was achieved after discontinuing the use of Tegafur suppositories.

Overexpression of p53 and erbB-2 was studied by immunohistochemistry in formalin-fixed tissue samples of 179 patients with transitional cell carcinoma of the urinary bladder. p53 immunostaining was strongly correlated with tumour stage (P < 0.0001). This was driven by a marked difference in p53 expression between pTa (37% positive) and pT1 (71%) tumours, while there was no difference between pT1 and pT2-4 tumours. Similarly, a strong overall association between p53 expression and grade (P < 0.0001) was driven by a marked difference between grade 1 (28%) and grade 2 tumours (71%), and there was no significant difference between grade 2 and grade 3 tumours. Surprisingly, the frequency of erbB-2 overexpression was higher in pT1 tumours (74%) than in either pTa (49%; P = 0.0265) or pT2-T4 (56%; P = 0.0645) tumours. Both p53 and erbB-2 expression was also associated with metastasis. Metastases were found in 77% of patients with p53 positive primary tumours, but in only 50% of the patients with p53 negative primary tumours (P = 0.022). Metastases were found in 66% of patients with erbB-2 positive primaries, but in only 37% of the erbB-2 negative primaries (P = 0.020). Of 32 patients with positivity for both p53 and erbB-2, 84% developed metastases, as compared to 49% of patients with positivity for either one or neither positive (P = 0.002). We conclude that both p53 and erbB-2 overexpression are associated with early invasion in bladder cancer. Furthermore, p53 and erbB-2 may be important predictors for metastasis.

A prospective immunohistochemical study of 66 human bladder biopsies with and without transitional cell carcinoma (TCC) of the bladder was performed to assess the diagnostic and prognostic value of laminin staining in TCC of the human bladder. In all normal and nonmalignant inflammatory specimens, a continuous intact basement membrane (BM) laminin could be identified. In bladder cancer specimens laminin staining revealed focal interruption of the subepithelial BM with microinvasion in 2 of 6 specimens initially diagnosed as Tis(Pis) and 7 of 25 specimens initially diagnosed as pTa tumors. A statistically significant association between the pT category and BM interruption was found (p < 0.025). BM loss was directly proportional with the stage of the tumor. However, no significant association could be observed between BM interruption and the grade of the tumor (p > 0.25). In a short-term follow-up (mean 16 months) a statistically significant correlation (p = 0.01) could be observed between tumor recurrence and BM integrity in that a higher recurrence rate and shorter recurrence-free interval was found in patients with interrupted BM versus those with intact BM. Assessment of the vascular BM-staining pattern revealed interruption in specimens from 5 patients who died from advanced metastatic tumors. The metastatic process was found to be closely associated with focal interruption of the subendothelial BM (p < 0.001). From our results it appears that the adjunct use of immunohistochemical laminin staining in the histopathologic examination of TCC of the bladder is essential in more exact identification of the different pathologic stages and is also of help in the more detailed prediction of tumor behavior and prognosis.

Cathepsin D is a widely expressed aspartyl lysosomal protease. Clinical studies in several tumor types have shown a strong correlation between cathepsin D expression and tumor progression. In breast carcinoma, its expression is an independent prognostic factor associated with an increased risk of death. However, there have been no studies evaluating cathepsin D in bladder tumors. Therefore, the aim of this study was to determine the pattern of expression of cathepsin D in a large series of bladder carcinomas and assess its role as a prognostic factor against established variables. The tumors from 105 patients (median age 73) (median follow-up 26 months) with transitional cell carcinoma of bladder were examined. Forty-nine patients had superficial tumors (16 pTa; 33 pT1), 56 had invasive tumors (14 pT2; 42 pT3); there were 35 grade 1/2 tumors and 70 grade 3 tumors. These were stained by a standard immunohistochemical technique with an anti-cathepsin D monoclonal antibody. All 4 normal bladder specimens were positive for cathepsin D. Fifty-four tumors (51%) were positive for cathepsin D and 51 (49%) were negative. Chi square analysis showed a significant positive relationship between negative cathepsin D expression and stage (p < 0.0005), grade (p < 0.0001) and tumor morphology (p = 0.001). There was no relationship between cathepsin D expression and tumor ploidy (p > 0.1) or patient age (p = 0.09). Univariate analysis of disease-free and overall survival showed that negative cathepsin D expression (p = 0.01 and p = 0.0003 respectively), stage (p = 0.004 and p < 0.005 respectively) and grade (p = 0.02 and p = 0.0007 respectively) were associated with significantly worse prognosis. However, in a multivariate analysis of age, stage, grade and cathepsin D expression, only stage remained significant for overall survival (p < 0.005). The observed result for cathepsin D in the univariate analysis is probably due to its strong association with grade and stage. Nevertheless, cathepsin D status was able to provide additional prognostic information for overall survival in invasive tumors when stratifying for grade (p = 0.047), which suggests that it might provide additional prognostic data within particular tumor stages.

Primary transitional cell carcinoma (TCC) of the bladder occurring during pregnancy is extremely rare and only 16 patients have been reported in the literature. Patient 1: A 24-year-old primigravida at 33 weeks of gestation presented with gross hematuria. Cystoscopy revealed a large bladder tumor. After delivery TUR-Bt was performed. Because of frequent reccurrences after TUR-Bt, radical cystectomy was done. Pathological study revealed transitional cell carcinoma, G1-G2, pTa. Patient 2: A 34-year-old gravida 11 at 6 weeks of gestation presented with gross hematuria. Cystoscopy revealed a papillary bladder tumor. TUR-Bt was performed after artificial abortion. Pathological study revealed papillary transitional cell carcinoma, G1 > G2, pTa. Eighteen patients of TCC of the bladder occurring during pregnancy were reviewed. Fifteen of the 18 patients presented with gross hematuria. All patients had superficial, solitary, grade 1 or 2 papillary TCC, except one grade 3 patient. Cystoscopy should be considered in all pregnant women with gross hematuria. Small TCCs of the bladder during pregnancy can be treated safely by TUR-Bt during pregnancy or after delivery.

Lately, nuclear morphometry methods are being used to analyze the malignant potential of tumoral cells. This paper presents a retrospective study of a series of 163 patients with the three histological grades (WHO), of superficial papillary transitional cell carcinoma (pTa-pT1) of the bladder with a mean follow-up of 60 months. A morphometric analysis of the initial tumour biopsies was made. Mean nuclear area (NA) and its standard deviation (NASD) were measured in a semi-automatic image analyzer (MOP-videoplan, Kontron). NA and NASD show increasingly higher values with increased grade (p < or = 0.0001). NA and NASD values raise in those progressing to muscle-infiltrant stage; tumours were, then, divided into two morphometric groups: small NA (< 50 microns 2) and large NA (> 50 microns 2); the difference between them being statistically significant. The likelihood of no tumoral progression at 30, 60 and 90 months was, respectively, 96, 94 and 92 percent, form small NAs, and 76, 65 and 64 percent for large NA (p < or = 0.0001).

Argyrophilic nucleolar organizer region (Ag-NOR) analysis, proliferating cell nuclear antigen (PC-NA/PC10) and MIB-1 immunohistochemistry, nuclear morphometry and DNA flow cytometry have been performed on formalin-fixed, paraffin-embedded biopsies from 50 patients with transitional cell carcinoma of the urinary bladder. The mean AgNOR count was 6.01 for the 17 grade 1 (G1), 7.59 for the 21 G2 and 13.33 for the 12 G3 carcinomas (p < 0.001). The mean PCNA score was 15.03% for G1, 24.04% for G2 and 40.01% for G3 cases (p < 0.001). The mean MIB-1 score was 11.31% for G1, 17.09% for G2 and 34.47% for G3 carcinomas (p < 0.001). The mean nuclear area was 35.53 microns2 for G1, 38.65 microns2 for G2 and 83.62 microns2 for G3 cases (p < 0.001). Aneuploidy rates were significantly higher (91.7%) in G3 than in G2 (42.9%, p < 0.01) or G1 cases (47.1%, p < 0.05) but not different for G1 versus G2 cases (p = 0.94). While many overlaps of values were seen between G1 and G2 tumours, no overlaps were found between G3 and G1/G2 tumours. Significant differences of values were also found between pTa and invasive tumours (p < 0.0001 for AgNOR count and PCNA score; p < 0.001 for MIB-1 score and mean nuclear area; p < 0.01 for DNA ploidy); however many overlaps were seen. Our findings indicate that the quantitative parameters obtained with different methods are associated with histological grade of bladder urotheliomas and may improve the grading reproducibility. In addition, the absence of overlaps between G3 and G2/G1 carcinomas supports the tendency to classify bladder urotheliomas in only two categories of malignancy.
