[Experiences with intensive radiotherapy of prostatic cancer in conjunction with surgery (transurethral resection, pelvic lymph node excision)].

Since 1981 a curative radiation treatment was performed in 84 patients with prostatic carcinoma. Previously, in 37 cases a transurethral resection of bladder outlet obstruction was done and in 18 patients a pelvic lymph node dissection was performed, whereas 29 patients were without operative therapy. Mild side effects of radiation could observed in all 3 groups in nearly the same portion (59/56/65%). However, in the group with transurethral resection after follow-up of 4,4 years severe late complications were found (cystitis, incontinence, urethral fistula). Therefore, radiation treatment of prostatic carcinoma after transurethral resection was abandoned. The cumulative 5-year-survival rate was 63% and in the TUR group only 41%. 9 out of 10 patients with histological verified lymph node metastases and radiation treatment are alive after mean follow-up time of 3.1 years without evidence of recurrent disease.

Perioperative single dose instillation of epirubicin or interferon-alpha after transurethral resection for the prophylaxis of primary superficial bladder cancer recurrence: a prospective randomized multicenter study--FinnBladder III long-term results.

PURPOSE: We evaluated the long-term efficacy of a single dose of interferon or epirubicin administered immediately after transurethral resection compared with transurethral resection alone for primary superficial bladder cancer recurrence. MATERIAL AND METHODS: A total of 200 patients with primary superficial stages Ta to T1, grades 1 to 3 bladder cancer were randomized into 3 treatment groups, including transurethral resection alone, transurethral resection plus 50 milliunits interferon-alpha2b and transurethral resection plus 100 mg. epirubicin. The primary end point was time to first recurrence. RESULTS: At a median followup of 72 months we observed a sustained effect of a single epirubicin instillation compared with other treatments. To date only 46% of the patients in group 3 have experienced recurrence in contrast to 73% and 68% in groups 1 and 2, respectively (p = 0.002). At 72 months the Kaplan-Meier disease-free estimates were 24%, 31% and 51% in groups 1 to 3, respectively (p = 0.002). The Cox multivariate model revealed a more than 2-fold relative risk of recurrence in group 1 versus group 3 (p <0.001). Other significant variables predicting recurrence were grade and the number of tumors. CONCLUSIONS: A single perioperative instillation of 100 mg. epirubicin causes a significant and sustained decrease in primary superficial bladder cancer recurrence, whereas a single dose of 50 milliunits interferon-alpha2b is ineffective for prophylaxis.

Unusual therapeutic response of massive squamous cell carcinoma of the bladder to aggressive radiation and surgery.

We report a case of stage D, poorly differentiated invasive squamous cancer of the bladder. Following transurethral resection of the tumor (170 gm.) and urinary diversion, the patient received 6,500 rad external radiation. After completion of radiation the bladder was converted from an inoperable (fixed to the pelvis) to an operable (mobile) condition. A cystectomy was performed and the patient was without evidence of disease 4 years later. The controversies of the therapeutic approach to squamous cancer of the bladder are discussed.

Novel prophylactic effect of doxifluridine in superficial bladder cancer.

OBJECTIVES: The prophylactic effect of 5'-deoxy-5-fluorouridine (5'-DFUR) has not been fully studied in superficial bladder cancer. The aims of this work were to investigate the prophylactic effects of 5'-DFUR in terms of tumor recurrence after transurethral resection of bladder tumor (TURBT) and to study whether thymidine phosphorylase (TdRPase) immunostaining predicts tumor recurrence. MATERIAL AND METHODS: A total of 112 patients with pTa or pT1 bladder cancer were eligible for the analysis and were allocated to either an adjuvant group (TURBT+5'-DFUR; n = 47; initial 23 months) or a control group (TURBT alone; n = 65, final 23 months). Tumor specimens were studied immunohistochemically using anti-TdRPase antibody. RESULTS: Tumor recurrence was observed in 54 of the patients (48%) after a median follow-up period of 26.8 months. No significant clinico-pathologic bias was observed between the two groups. Although patients in the adjuvant group had a significantly higher recurrence-free survival rate than those in the control group when considering 78 patients with pathological T1 tumors (p = 0.0272) and 65 patients who did not recur within 12 months (p = 0.001), overall there was no significant difference between the two groups. Multivariate analysis revealed that 5'-DFUR administration was the strongest predictor of late tumor recurrence, which was defined as development of recurrence 12 months after TURBT (hazard ratio 5.744; 95% CI 1.495-30.45; p = 0.0094). Immunostaining did not predict prophylactic effects of 5'-DFUR. Mild, reversible toxicity was found in 9/58 (15.5%) of the cases evaluated. CONCLUSIONS: Oral administration of 5'-DFUR after TURBT did not prevent tumor recurrence in the overall cohort, although this novel drug may have a prophylactic effect in patients belonging to several subgroups.

Conservative treatment with transurethral resection, neoadjuvant chemotherapy followed by radiochemotherapy in stage T2-3 transitional bladder cancer.

PURPOSE: Organ preservation has been investigated in patients (p) with infiltrating transitional cell carcinoma (TCC) of the bladder over the past decade as an alternative to radical cystectomy. This is a trimodal schedule study, including transurethral resection of bladder tumor (TURB), neoadjuvant chemotherapy and concomitant radiochemotherapy (RTC). PATIENTS AND METHODS: From April 1996 until August 2005, 29 evaluable patients (p) with T2-T3NXM0 bladder cancer were enrolled. After a transurethral resection of bladder tumor (TURB), we administered 2 cycles of induction chemotherapy with CMV (15 p) or Gemcitabine-Cisplatin (14 p) followed by radiotherapy 45 Gy 1.8 Gy/fraction and two cycles of concomitant cisplatin 70 mg/m(2). 2-3 weeks later, a cystoscopy with tumor-site biopsy was performed. If complete histological response, p were treated with consolidation radiotherapy until 64.8 Gy. For p with residual or recurrent tumor, cystectomy was performed. RESULTS: We included 28 men and 1 women (median age 63, range 39-72 years) with PS (ECOG) 0-1. The stage was: 21 p T2; 6 p T3a; and 2 p T3b. Toxicity was higher in CMV compared with Gem- Cis: grade (3/4) neutropenia 4/15 (26%) vs 1/14 (7%); febrile neutropenia 3/15 (20%) vs 1/14 (7%); grade (3/4) trombocytopenia 2/15 (13%) vs 1/14 (7%). Toxicities with concomitant RCT were low-moderate: urocystitis (26%) and enteritis (18%). RESPONSE: microscopically complete TURB was obtained in 20 p (69%), but not in 9 p (31%) (7 microscopic, and 2 macroscopic residual tumor). We found a complete histologic response after induction RCT in 25 p (86%). After a median follow-up of 69.4 months (m) (range: 8-97.7), there were 8 deaths, with a overall survival of 72%. Furthermore 14 of 29 p (48%) were alive with intact bladder, and median survival time with intact bladder was 63.6 m (50.1-77.2); were predictive of best outcome T2 stage vs T3 (p < 0.0001), and complete histologic resection in initial TURB vs residual tumor (p = 0.0004). CONCLUSIONS: Combined treatment provide high response rates and can be offered as an alternative option to radical cystectomy in selected patients with TCC. Patients with T2 stage and complete histologic resection in initial TURB had the best outcome.

5-aminolevulinic acid-induced fluorescence endoscopy applied at secondary transurethral resection after conventional resection of primary superficial bladder tumors.

OBJECTIVES: A prospective investigation was carried out to evaluate the use of 5-aminolevulinic acid (5-ALA)-induced fluorescence diagnosis with secondary transurethral resection (TUR). METHODS: Fifty patients underwent secondary TUR of the former resection area 6 weeks after conventional TUR for superficial bladder carcinoma. 5-ALA-induced fluorescence diagnosis was used in addition to standard white light endoscopy. All former resection areas were biopsied regardless of fluorescence findings. In addition, specific red fluorescent areas were resected, as were suspicious areas seen at white light endoscopy. RESULTS: One hundred thirty areas or tumors were resected. The sensitivity of fluorescence cystoscopy was 77.8% (95% confidence interval 52.4% to 93.6%). Residual tumors were found in the area of the former resection in 7 (14%) of 50 patients; 4 of these 7 were fluorescence negative and 3 were fluorescence positive. In an additional 7 patients (14%), exclusively fluorescing tumors not visible under white light could be detected outside the areas of former resection (n = 5, Stage pTaG1/2; n = 1, Stage pT1G1/2; n = 1, carcinoma in situ). CONCLUSIONS: Despite high sensitivity, fluorescence diagnosis at this early stage of control does not allow us to evaluate sufficiently the granulation tissue of necrotic areas after TUR without biopsy. The main advantage of the 5-ALA-induced fluorescence endoscopy is in the evaluation of untreated urothelium because of the easier detection of tumors not visible by conventional endoscopy.

Chromosomal numerical aberrations detected by fluorescence in situ hybridization on bladder washings from patients with bladder cancer.

OBJECTIVE: Previous studies on touch biopsy specimens have determined numerical or structural changes involving many different chromosomes in bladder cancer. The aim of this study was to evaluate the use of fluorescence in situ hybridization (FISH) assay in bladder washings as an objective technique to detect chromosomal numerical aberrations in bladder cancer. The main advantages of bladder washings are that they can be easily collected during the clinical follow-up of patients with superficial bladder cancer and they do not contain so many degenerate cells as urine samples. METHODS: We collected specimens from 25 patients who underwent transurethral resection of bladder tumors. Double target FISH assays with centromeric labeled probes for chromosomes 7, 8, 9 and 11 were used on the bladder washings and on the touch biopsy slides. The results were compared to flow cytometry and tumor grade and stage. RESULTS: We found monosomy 9 and trisomy 7, 8, 9 and 11 in 28, 32, 36, 28 and 25% respectively of the patients. FISH analysis of bladder washing versus touch biopsy specimens were concordant in approximately 90% of the slides. Total DNA aneuploidy correlated well with numerical aberrations of chromosomes 7, 8 and 11, but not with chromosome 9. CONCLUSION: Although better hybridization efficiency was obtained on touch biopsy slides, the results in bladder washings were in high concordance. FISH analysis on bladder washing samples may become a simple tool to improve the accuracy of cytology.

[Cytological diagnosis from random mucosal biopsies using implant technique during operation].

A purpose of mucosal random biopsy of urinary bladder is to get informations about the extent of cancerous lesion and the existence of rest of cancer. For the purpose of determining the care range of the operation and postoperative treatments by getting these informations during the operation, we drew up stamp cytological preparations for mucosal random biopsy of urinary bladder performed during TUR-Bt, and examined potency of application of this method to quick diagnostics. First of all, 15 times of transurethral resections of bladder cancers were performed on 14 cases, and 19 of imprint preparations were made from the excised tumor materials during operation. Then the accuracy rate of the rapid cytology was evaluated based on permanent preparations that were made simultaneously. The accuracy rate of the intraoperative rapid cytology was 84.2%. Next, a similar procedure was performed on 68 materials of random biopsy during the above-mentioned operation. The accuracy rate of imprint cytology was 73.5%. The relatively low accuracy rate of rapid cytology must be attributed to diagnostic difficulty noted when dealing with Papanicoloau class 3. For all above, it was suggested that rapid implant cytology during operation must be applicable to quick diagnostics.

Value of 11C-choline PET and contrast-enhanced CT for staging of bladder cancer: correlation with histopathologic findings.

UNLABELLED: Lymph node involvement is a major prognostic factor in bladder cancer, but the accuracy of conventional imaging modalities for the prediction of regional and distant metastatic diseases is limited. This study was performed to compare the diagnostic accuracies of contrast-enhanced CT and PET with (11)C-choline for the staging of urothelial bladder cancer. METHODS: Twenty-seven patients (median age, 69.1 y) who had urothelial bladder cancer and who were referred for radical cystectomy and pelvic lymph node dissection (PLND) on the basis of a histologic evaluation after transurethral resection of bladder cancer (TURB) were studied. PET scanning, using 2 multiring whole-body tomographs, was performed 5 min after intravenous injection of approximately 370-500 MBq of (11)C-choline. In addition, conventional bone scintigraphy and contrast-enhanced CT were performed. After imaging, cystectomy and PLND were performed in all patients. Pathologic (11)C-choline uptake that could not be explained by intestinal activity was noted as a positive result. Node positivity was determined by size on CT: nodes measuring more than 1 cm in the long axis were described as being positive for tumor. Histopathologic findings were used as a reference. RESULTS: The presence of residual bladder cancer (pTa-pT4) was correctly detected in 21 of 25 histologically tumor-positive patients (84%) by CT and in 24 of 25 patients (96%) by (11)C-choline PET. Lymph node involvement was correctly detected in 4 of 8 patients (50%) by CT and in 5 of 8 patients (62%) by (11)C-choline PET. The median size of the 3 nodes with false-negative PET results was 9 mm (range, 6-21 mm), and the median size of the metastatic lesions within the lymph nodes was 3 mm (range, 1-15 mm). CT resulted in 6 (22%) false-positive lymph nodes, whereas none was demonstrated by (11)C-choline PET; these data indicated a significantly higher accuracy of PET than of CT (P < 0.01). Both modalities missed a small peritoneal metastasis verified by histologic evaluation. No positive results were obtained from bone scintigraphy. CONCLUSION: These preliminary data suggest that (11)C-choline PET is comparable to CT for detecting residual bladder cancer after TURB but appears to be superior to CT for the evaluation of potential additional lymph node metastases. (11)C-choline PET should be further evaluated for staging in patients who have bladder cancer and who are scheduled for radical cystectomy.

RTOG 97-06: initial report of a phase I-II trial of selective bladder conservation using TURBT, twice-daily accelerated irradiation sensitized with cisplatin, and adjuvant MCV combination chemotherapy.

To examine combination cisplatin and twice-daily accelerated irradiation (RT) after aggressive transurethral resection of bladder tumor (TURBT) in an attempt to preserve the bladder and to determine the likelihood that patients who complete this regimen could then complete three cycles of methotrexate, cisplatin, vinblastine (MCV) chemotherapy. Between 1998 and 2000, 52 patients with Stage T2-T4aN0M0 disease, from 17 institutions, were entered into the trial. Forty-seven patients were deemed eligible; the planned accrual was 40. Of the 46 patients, 68% were >60 years old, 70% were men, and 96% had a Karnofsky score >/=90. The clinical T stage was T2 in 66%, T3a in 25%, and T3b in 9%. The median follow-up at the time of analysis was 26 months. The protocol required TURBT within 6 weeks of the initiation of induction therapy. Induction treatment involved 13 days of concomitant boost RT, 1.8 Gy to the pelvis in the morning followed by 1.6 Gy to the tumor 4-6 h later. For sensitization, cisplatin (20 mg/m(2)) was given on the first 3 days of each treatment week. Three to four weeks after induction, patients were evaluated cystoscopically for residual disease. Patients whose biopsies and cytologic evaluations showed no disease completed consolidation chemoirradiation. Patients with residual tumor went on to cystectomy. After either consolidation or cystectomy, patients were to complete three cycles of MCV chemotherapy. Of the 47 patients, 45% completed all phases of the protocol treatment with minor, or no, deviations. Five patients refused either the postinduction evaluation or cystectomy and 6 refused adjuvant chemotherapy. The CR rate after induction therapy was 74%. For 2 patients, residual disease after induction was limited to positive cytologic findings, and for 8 patients, biopsy of the primary site revealed persistence. Of the 8 cystectomy patients, 2 had no evidence of disease in the bladder at pathologic review of the surgery specimen. Grade 3 toxicity related to chemotherapy was observed in 11% of patients during both induction and consolidation, and in 41% during adjuvant chemotherapy. A total of 8 patients (36% of those receiving adjuvant chemotherapy) went on to develop Grade 4 neutropenia or thrombocytopenia during additional adjuvant chemotherapy. Grade 3 toxicity due to RT was seen in 4% and 0% of patients during induction and consolidation, respectively. One patient developed Grade 4 hydronephrosis during consolidation. The projected 36-month value for locoregional failure, distant metastasis, overall survival, and bladder-intact survival was 27%, 29%, 61%, and 48%, respectively. After aggressive TURBT, twice-daily accelerated RT initiated in concomitant-boost format is well tolerated and results in a rate of complete response (74%) similar to that in previous bladder-sparing trials. The projected 2-year values for locoregional control, bladder-intact survival, and overall survival were also consistent with previously reported trials of bladder-sparing treatment. With only 45% of patients completing three cycles of MCV, this form of adjuvant chemotherapy appears to be poorly tolerated by most patients.

A comparison of urinary nuclear matrix protein-22 and bladder tumour antigen tests with voided urinary cytology in detecting and following bladder cancer: the prognostic value of false-positive results.

OBJECTIVES: To evaluate the diagnostic and prognostic value of the nuclear matrix protein-22 (NMP22) and bladder tumour antigen (BTAstat) tests compared with voided urinary cytology (VUC) in detecting and following bladder cancer, assessing particularly the prognostic value of false-positive test results in patients followed up for bladder cancer. PATIENTS AND METHODS: From 739 patients suspected of having bladder cancer, voided urine samples for the NMP22 and BTAstat tests, and for VUC and urine analysis, were collected before cystoscopy. All patients underwent transurethral resection of bladder lesions or mapping. and were followed for a mean (range) of 27.3 (3-65) months. RESULTS: In the 406 patients with bladder cancer, the overall sensitivity was 85% for NMP22, 70% for BTAstat and 62% for VUC. For histological grades 1-3 the sensitivity in detecting transitional cell carcinoma was 82%, 89% and 94% for NMP22, 53%, 76% and 90% for BTAstat, and 38%, 68% and 90% for VUC, respectively. Although the sensitivity in detecting invasive carcinoma was >85% for all the tests. NMP22 and BTAstat were statistically more sensitive than VUC for superficial tumours. The optimal threshold value for NMP22, calculated using the receiver operating characteristics curve was 8.25 U/mL. The specificity was 68% for NMP22, 67% for BTAstat, and 96% for VUC. The specificity of VUC remained >87% and was independent of benign histological findings. In contrast, in patients with no apparent genitourinary disease on histology, NMP22 and BTAstat had significantly higher specificity (94% and 92%, respectively: P=0.003) than in the group with chronic cystitis (52% for both tests). Forty patients having no bladder cancer at biopsy had a recurrence after a mean (range) follow-up of 7.7 (3-15) months: all had a previous history of bladder cancer. According to subsequent recurrence, the prognostic positive and negative predictive values were 18% and 91% for NMP22, 13% and 88% for BTAstat, and 79% and 91% for VUC. Both false-positive VUC and NMP22 tests predicted recurrence (log-rank test, P<0.001 and P=0.004, respectively), but the BTAstat test produced no similar correlation (P=0.778). CONCLUSION: The NMP22 and BTAstat tests are better than VUC for detecting superficial and low-grade bladder cancer but they have significantly lower specificity. After excluding diseases with the potential to interfere in these tests the overall specificity of both tests is increased considerably. False-positive results from NMP22 and VUC but not from BTAstat in patients followed up for bladder cancer correlate with future recurrences.

Decreased expression of transforming growth factor beta receptor type I is associated with poor prognosis in bladder transitional cell carcinoma patients.

Transforming growth factor (TGF) beta, a potent growth inhibitor of proliferation in most cells, usually exerts its effects through an interaction with membrane receptors, type I (TbetaR-I) and type II (TbetaR-II). In the present study, the expression of TGF-beta receptors was correlated with tumor grade, pathological stage, and probability of progression and survival in patients with bladder transitional cell carcinoma (TCC). To this end, immunohistochemistry was carried out in specimens obtained from 59 patients who underwent either radical cystectomy or transurethral resection of bladder tumor. Among these patients, 18 (30.5 %) had loss of TbetaR-I expression, whereas 27 (44.0%) had loss of TbetaR-II expression. There was a correlation between the loss of expression of TbetaR-I and TbetaR-II and the tumor grade (P = 0.041 and P = 0.026, respectively). In addition, both pathological and lymph node status also were associated with the loss of TbetaR-I and TbetaR-II expression (P = 0.025 and P = 0.004, respectively). Interestingly though, only the loss of expression of TbetaR-I was associated with an increased probability of tumor progression and a decreased probability of survival (P = 0.0046 and P = 0.0022, respectively). These results suggest that the status of TbetaR-I expression may be a potential prognostic marker in patients with bladder TCC.

Organ preservation approaches with radiation therapy in muscle-invasive bladder carcinoma.

Combined modality treatments with organ preservation intent have become standard oncological treatment in many tumour sites. Although radical cystectomy had been considered to be the standard treatment, combined modality treatment has been used in muscle-invasive bladder carcinoma with excellent results, especially in patients with T2-3a disease without obstructed ureters. The components of the combined treatment are usually transurethral resection of bladder tumour (TURBT) followed by concurrent chemotherapy and radiation. Interim cystoscopic assessment after the initial portion of radiation is often utilised to identify patients at high risk of local failure, ie. those who do not achieve a complete response, and these patients are then recommended to undergo immediate salvage cystectomy. Delaying cystectomy does not appear to decrease the survival or increase the incidence of distant metastasis. The local control rates for TURBT alone, chemotherapy alone and radiation therapy alone are only 20%, 20% and 30% to 45% respectively. When the above three are combined together, a complete response rate of 75% can be achieved and 85% of these remain free from invasive recurrence. Combined modality treatment offers an overall survival rates which is comparable with modern radical cystectomy series: about 50% at 5 years, and in addition, it offers a 5-year survival rate with an intact bladder of 41% to 43%. With the close collaboration among urologists, medical oncologists and radiation oncologists, organ preservation approaches can achieve excellent results in muscle-invasive bladder carcinoma and this option should be presented to patients as an alternative to radical cystectomy.

[Simultaneous treatment for benign prostate hyperplasia and its concomitant diseases].

OBJECTIVE: To investigate the surgical treatment of benign prostate hyperplasia (BPH) and its concomitant diseases at the same time. METHODS: One hundred and fourteen operations were performed for BPH patients, including transurethral resection/vapor of the prostate (TURP/TUVP), inguinal herniorrhaphy, internal urethrotomy, transurethral resection of bladder tumor (TURBt) or vesical litholapaxy, and the data were reviewed. RESULTS: The procedures were successful in all cases. A follow-up of 3 to 60 months found a good outcome of TURP. There was no recurrence in 30 cases of inguinal hernia and 39 cases of vesical calculus. Of the 25 cases of urethral stricture, 1 had an obvious hypotension during the operation and 4 needed urethral dilatation after operation. Six of the 20 cases of bladder tumor underwent a second TURBt due to the recurring tumor which was far from prostatic urethra. CONCLUSION: Inguinal hernia, urethral stricture, bladder tumor or vesical calculus can be treated simultaneously during TURP.

Implantation metastasis after a suprapubic catheter in a case of bladder cancer.

We report about a patient who was treated with a percutaneous suprapubic cystostomy in order to relieve repeated urinary retention. Two hours later a bladder tumor was found and the suprapubic catheter was removed. After transurethral resection of the bladder tumor the histological specimen showed a pT3 G3 squamous cell carcinoma. Because of the age and reduced performance status of the patient a radical cystectomy was contraindicated. In a second approach we performed again a transurethral resection of the bladder tumor simultaneously with a resection of the prostate. Eight weeks later the patient was admitted to our hospital because of reduced performance status and gross haematuria. We found a widespread bladder tumor with an implantation metastasis in the abdominal wall at the site where the suprapubic catheter was placed and multiple lung metastases. The patient died within one week after admission. The literature is reviewed and therapeutic strategies are discussed.

Pre and postoperative quantitative detection of fragments of cytokeratins 8 and 18 (UBC IRMA) as markers of early recurrence of superficial bladder tumor.

OBJECTIVES: The Urinary Bladder Cancer (UBC) test is a marker that detects urinary fragments of cytokeratin 8 and 18. The aim of this study is to evaluate the usefulness of the pre and post operative UBC test to detect early recurrences of a bladder tumor in the first year after the transurethral resection of a bladder tumor. MATERIALS AND METHODS: A multicentric perspective study on 36 patients with superficial bladder cancer (pTa-pT1) treated with transurethral resection (TUR) was performed. Each patient underwent 4 specific urine collections: 1) preoperatively, 2) 3 days after TUR, 3) 7 days after TUR, 4) 30 days after TUR. UBC was analysed on urine with the IRMA method and the cut off value of 12 mg/L was used. Cystoscopy was performed after 3, 6, 9, and 12 months after TUR, with the aim of identifying all cancer recurrences in the first year postoperatively. Statistical analyses to identify differences between patients with or without early recurrence were performed in accordance with Fisher's exact test and Chi-square analysis. RESULTS: Of the 36 patients included in the study 15 showed early recurrence and 21 were recurrence free 1 year after surgery. UBC levels measured in recurrence free patients 30 days after TUR showed normal values, values decreasing as compared with preoperative levels or both circumstances, even if a statistically significant difference was not found between the two groups. CONCLUSIONS: In this study we reported an insignificant correlation between the postoperative modifications of UBC levels and the risk of tumor recurrence during the first year of follow-up. A larger study group with longer follow-ups will probably allow better evaluation of the real power of UBC tests in clinical practice.

Role of chronic catheterization in the development of bladder cancer in patients with spinal cord injury.

OBJECTIVES: Patients with spinal cord injury (SCI) and chronic indwelling catheters are known to be at increased risk of bladder malignancy. "Decatheterization" by clean intermittent catheterization, external condom catheterization, or spontaneous voiding is thought to reduce the risk by decreasing the chronic mucosal irritation and rate of infection. We examined two Department of Veterans Affairs (DVA) data bases to test this theory. METHODS: A population-based retrospective analysis of invasive treatments for carcinoma of the bladder in all DVA hospitals was conducted using computerized inpatient files from fiscal years 1988 to 1992. RESULTS: One hundred thirty patients with bladder malignancy were identified from a pool of 33,565 patients with SCI (0.39%). All 130 patients underwent either radical cystectomy (n = 63, 48%) or transurethral resection of bladder tumor (n = 67, 52%). The 30-day perioperative mortality and overall 5-year survival rates were 2 (1.5%) and 49 (38%) of 130, respectively. Of the 130 patients analyzed, 42 (32%) had adequate data available regarding tumor pathologic findings and method of bladder management for analysis. The average age at diagnosis was 57.3 years. The histologic finding was transitional cell carcinoma in 23 (55%), squamous cell carcinoma in 14 (33%), and adenocarcinoma in 4 (10%) of 42. Bladder management was an indwelling urethral catheter in 18 (43%), suprapubic catheter in 8 (19%), clean intermittent catheterization in 8 (19%), and condom catheter in 6 (14%) of 42 patients. Squamous cell carcinoma was more common in patients with indwelling urethral catheters and suprapubic tubes (11 of 26, 42%) than in those using clean intermittent catheterization, condom catheterization, or spontaneous voiding (3 of 16, 19%). CONCLUSIONS: Bladder cancer was diagnosed in approximately 0.39% of this large SCI population during a 5-year period. Most cancers (55%) were transitional cell carcinomas. Squamous cell carcinoma was more common in patients with SCI and indwelling catheters than those without chronic catheterization. These data continue to suggest that avoidance of indwelling catheters, when feasible, is the preferred method of bladder management in patients with SCI.

Role of ultrasonography and urinary cytology in diagnosing recurrence of superficial urinary bladder cancer compared to cystoscopy.

Urinary cytology, ultrasonogram of the urinary bladder and cystoscopy were done in 99 cases of urinary bladder cancer patients in the department of urology of Dhaka Medical College Hospital (DMCH), Dhaka, during the period from January 1997 to December 1998. Pre transurethral resection of bladder tumour (TURBT), urinary cytology was positive in 20.20% cases and ultrasound scan was positive in 96.9% cases. Histopathological examination revealed 95.96% as transitional cell carcinoma:- Grade I (3.0%), Grade II (62.6%) and Grade III (34.4%). During follow-up urinary cytology was positive in only one case whereas ultrasound scan was positive in 53.5% cases of whom only 21.6% patients had actual recurrent bladder tumours proved by cystoscopy. Statistical analysis of the three tests and histopathology showed significant variation though by Chi-square test the ultrasound scan is found superior to urinary cytology. We conclude when ultrasonography of the urinary bladder shows any suspected lesion it should be examined by cystoscope and biopsy should be taken from the suspected area for confirmation. Neither urinary cytology nor ultrasound scan can replace cystoscopic examination.
