[A case of urothelial carcinoma associated with penile metastasis].

A 71-year-old man, who had been treated with continuous ambulatory peritoneal dialysis due to chronic renal failure for 5 months, visited our hospital with a complaint of penile induration in April, 1998. He underwent wedge biopsy of the penis. On the day after the biopsy, he had an episode of gross hematuria. Cystoscopy revealed a papillary tumor that seemed to have arisen from the right ureteral orifice and another in the trigone. Computed tomographic scan revealed the bladder tumors and swelling of the internal iliac lymph nodes. The bladder tumors were resected transurethrally. The pathological diagnosis of the specimen from the penile induration was metastatic transitional cell carcinoma.

[Two cases of encrusted cystitis].

Encrusted cystitis is a type of severe cystitis, which progresses chronically and is characterized by excessively alkaline urine and calcifications within the bladder wall. We report two cases of encrusted cystitis. Both cases were high aged and had severe anemia with chronic cystitis. They complained of gross hematuria, voiding frequency and pain upon urination. Urine pH was 8-9, and urine cytology was negative. Urine culture contained Corynebacterium Group D2. Abdominal computed tomography and transurethral resection revealed wall bladder wall calcification and inflammatory change. We diagnosed it as encrusted cystitis. The patients underwent excision of plaques of calcified encrustation, adapted antibiotic therapy and acidification of urine. It is essential to diagnose encrusted cystitis early and to provide adequate treatment promptly.

Organ preservation in the management of bladder and prostate cancer.

Optimal management of bladder cancer is still controversial. With radiotherapy organ preservation is achieved in 30% of patients in the absence of unfavorable factors. Better results are achieved with accelerated fractionation, neoadjuvant chemotherapy or concomitant radiochemotherapy. In particular, with the latter, the rate of complete response (70%) is 30% higher as compared to radiotherapy alone or transurethral resection (TUR) of bladder and chemotherapy. In the treatment of intracapsular prostate cancer, radiotherapy is a valid alternative to prostatectomy with comparable results in terms of disease-free survival. In case of extraprostatic disease, results are clearly less satisfactory because of lower local control and blood-borne metastases. Conformal radiotherapy and neoadjuvant and adjuvant hormonotherapy are being studied to improve results.

Evaluation of nuclear matrix protein 22 (NMP22) as a tumor marker in the detection of bladder cancer.

We prospectively evaluated the performance of urinary NMP22 test in the detection of transitional carcinoma (TCC) of the bladder. Urine samples were obtained from 39 patients with known bladder cancer, 37 patients with primary hematuria. 18 with benign urological conditions and 20 healthy subjects. Overall sensitivity and specificity of NMP22 with reference value of 10 U/ml was 72 and 73%, respectively. Sensitivity for pT1 and pT2 tumors was 83%, whereas that for pTa tumors was 55%. When the test was determined before and after transurethral resection (TUR) of bladder tumor, it was shown that the TUR effected the NMP22 level. Urinary NMP22 was highly sensitive for high-risk bladder cancer. However, the sensitivity of the test is somewhat lower in low grade and stage tumors. Additionally, the effect of previous resection limits its value in the follow up of patients with superficial tumors. The larger series with longer follow up may lead us to determine the time to neglect the effect of TUR on NMP22 and the test kit should be upgraded by the manufacturer to exclude the false positive results due to inflammatory conditions.

Intravesical combined chemoimmunotherapy with epirubicin and bacillus Calmette-Guérin is not indicated for superficial bladder cancer.

PURPOSE: The short-term effects of intravesical chemoimmunotherapy with epirubicin and bacillus Calmette-Guérin (BCG) administered repeatedly for prophylaxis of recurrence of superficial bladder cancer (pTa, pT1) were investigated in 24 patients aged a median of 70 years between March 1996 and February 1999, and were compared with those of BCG monotherapy in 50 patients from March 1990 to February 1999. PATIENTS AND METHODS: The patients underwent intravesical instillation of the Tokyo strain BCG with or without epirubicin after transurethral resection (TUR) of bladder cancer. For the combined treatment, at 1-2 weeks after TUR, epirubicin (40 mg) and BCG (80 mg) were istilled into the bladder by turns once a week for 12 weeks. For the group receiving only BCG, 80-mg instillations were done with the same schedule. Thereafter, the patients were followed by cystoscopy and urinary cytology every 3 months for up to 3 years after intravesical therapy. RESULTS AND CONCLUSIONS: At 2 years after treatment, the simple recurrence rate was 26.1% (6/23) in patients with chemoimmunotherapy and 32.0% (16/50) in BCG-treated patients. Adverse reactions, including increased frequency of urination, urgency and miction pain, were observed in 18 patients (85.7%) undergoing chemoimmunotherapy and 58.0% undergoing BCG monotherapy. One patient receiving chemoimmunotherapy was withdrawn from treatment because of symptoms of severe bladder irritation due to the instillation. Intravesical chemoimmunotherapy using epirubicin and BCG was finally found to be inferior in comparison with BCG monotherapy for the prophylaxis of recurrence of superficial bladder cancer.

Prevention of the Recurrence of Superficial Bladder Cancers: Intravesical Instillation of Bacillus Calmette-guerin Versus Bacillus Calmette-guerin Plus Epirubicin.

Purpose The short-term effects of intravesical chemoimmunotherapy with epirubicin and Bacillus Calmette-Guerin (BCG) administered repeatedlly for prophylaxis of recurrence of superficial bladder cancer (pTa, pT1) were investigated in 22 patients with a median of 70 years between March, 1995 and February, 1999, and were compared with those of BCG monotherapy in 50 patients between March, 1995 and February, 1999. Patients and Methods The patients underwent intravesical instillation of Tokyo-strain BCG with or without epirubicin after transurethral resection (TUR) of bladder cancer. For the combined treatment, at 1~2 weeks after TUR, epirubicin (40 mg) and BCG (80 mg) were instilled into the bladder by turn once a week for 12 weeks. For the BCG alone group, 80 mg instillation were performed with the same schedule. Thereafter, the patients were followed by cystoscopy and urinary cytology every 3 months for up to 3 years after intravesical therapy. Results and Conclusions The simple recurrence rate was 22.7% (5/21) in patients with chemoimmunotherapy and 32.0% (16/50) in BCG-treated patients. Adverse reactions, including increased frequency of urination, urgency and miction pain, were observed in 18 patients (85.7%) undergoing chemoimmunotherapy and 58.0% undergoing BCG monotherapy. One patient receiving chemoimmunotherapy was withdrawn from treatment because of severe bladder-irritation symptoms due to instillation. Intravesical chemoimmunotherapy using epirubicin and BCG was inferior in comparison with BCG monotherapy for prophylaxis of recurrence of superficial bladder cancer.

Noninvasive detection and prediction of bladder cancer by fluorescence in situ hybridization analysis of exfoliated urothelial cells in voided urine.

OBJECTIVES: To investigate the clinical utility of fluorescence in situ hybridization (FISH) of voided urine in the detection of bladder cancer and the prediction of its recurrence. METHODS: FISH with centromere-specific probes for chromosomes 9 and 17 was performed to evaluate the chromosomal alterations of exfoliated urothelial cells in voided urine obtained from 44 patients with bladder cancer and 20 controls. The analysis was also performed in 17 patients with bladder cancer after complete transurethral resection to prospectively determine whether FISH can predict tumor recurrence. RESULTS: The sensitivity to detect bladder cancer by FISH analysis (85%) was significantly higher than that by urine cytologic examination (32%) and by the bladder tumor antigen test (64%) (P <0.0001 and P = 0.026, respectively). The specificity of FISH, cytologic analysis, and the bladder tumor antigen test was 95%, 100%, and 80%, respectively. Among the 17 patients tested after transurethral resection, 7 of 13 FISH-positive patients developed tumor recurrence within the 27-month follow-up period; none of 4 FISH-negative patients developed recurrence during the same period. The recurrence rate in patients with the loss of chromosome 17 was 100%, significantly higher than the 23% for patients without this alteration (P = 0.015). CONCLUSIONS: These findings suggest that FISH analysis of exfoliated urothelial cells in voided urine can efficiently detect bladder cancer and predict its recurrence.

[Non-invasive urine tests in diagnosis and as prognostic markers for urinary bladder carcinoma. Comparison of the BTAstat and NMP 22 tests with immunocytology using monoclonal antibodies against Lewis X and 486p3/12].

INTRODUCTION AND OBJECTIVES: The non-invasive detection of urothelial carcinoma remains challenging. The aim of this study was the prospective evaluation of urine markers for bladder carcinoma. We compared the NMP 22 and BTAstat tests with immunocytology (IC) using monoclonal antibodies against the Lewis X antigen and against 486p3/12. METHODS: NMP 22 and BTAstat were performed on urine samples, and IC with 486p3/12 and Lewis X staining was performed on urine samples as well as bladder wash specimens ( n=146) in patients ( n=115) undergoing transurethral resection on suspicion of bladder cancer (70 specimens) or follow up cystoscopy because of a history of bladder cancer (76 specimens). Bladder cancer was detected in 54 patients (pTa: n=25, pT1: n=20, pT2: n=8, CiS: n=1). Cut-off levels were 10 U/ml for the NMP 22, 30% positive cells for 486p3/12, and 5% positive cells for the Lewis X test. RESULTS: The BTAstat test was positive in 65 (44.5%) cases, the NMP 22 in 69 (47.3%) cases, IC with 486p3/12 and the Lewis X was positive in 52 (35.6%) and 109 (74.7%) cases, respectively. Sensitivity was 70.3% (BTAstat), 68.5% (NMP 22), 94.4% (Lewis X), and 68.5% (486p3/12), respectively. The specificity was 70.6% (BTAstat), 65.2% (NMP 22), 36.9% (Lewis X), and 83.6% (486p3/12), respectively. Among the patients with a false positive test 2/22 (9.0%) patients (BTAstat), 2/25 (8%) patients (NMP 22 test), 4/43 (9.3%) patients (Lewis X), and 3/11 (27%) patients (486p3/12), respectively, suffered from tumor recurrence. In contrast, among the patients with a correct negative test 2/39 (2.0%) (BTAstat), 2/36 (0.5%) (NMP 22), 0/18 (0%) (Lewis X), and 1/50 (2.0%) (486p3/12), respectively, suffered from tumor recurrence. CONCLUSIONS: IC with the Lewis X revealed a higher sensitivity than all of the tested, commercially available methods. Because of its high sensitivity and its high negative predictive value, the Lewis X test may be useful for screening a high-risk population. Patients with a false positive 486p3/12 test have an increased risk of tumor recurrence when compared with patients with a correct negative test.

Immunolocalization of transitional cell carcinoma of the bladder with intravesically administered technetium-99m labelled HMFG1 monoclonal antibody.

The aim of this study was the immunolocalization of transitional cell carcinoma of the bladder with a radiolabelled murine tumour-associated monoclonal antibody and the measurement of the absolute uptake of the antibody by the tumour. Fourteen patients with transitional cell carcinoma of the bladder received 3-6 mCi (111-222 MBq) of technetium-99m labelled HMFG1 monoclonal antibody intravesically and one patient, 2 mCi (74 MBq) of iodine-131 labelled 11.4.1, which is a non-tumour-specific monoclonal antibody. Four of the 15 patients were evaluated with single-photon emission tomography (SPET) 1 1/2 to 2 h post administration. All patients underwent transurethral resection of the bladder tumour within 12-20 h following intravesical administration of the radiolabelled antibody. The radioactivity of biopsy specimens from normal urothelium and tumour areas were counted in a gamma counter. The mean uptake of the radiolabelled antibodies from normal and tumour sites was expressed as a percentage of the administered dose per kilogram of tissue. Conventional histology and immunohistochemistry using HMFG1 monoclonal antibody were performed on paraffin sections of the biopsy specimens. Although our results are preliminary, it can be concluded that: (a) bladder tumours are well imaged by SPET when using 99mTc-HMFG1; (b) intravesically administered radiolabelled antibody remains on the bladder tissue and does not escape into the systemic circulation; (c) the wide range of tumour uptake values (0%-9.3% administered dose/kg) observed probably can be attributed to heterogeneity of the antigenic expression of the tumour; (d) values of 99mTc-HMFG1 monoclonal antibody uptake by the tumour do not justify future attempts at radioimmunotherapy.

[The staging of bladder tumors in MRT: the value of the intravesical application of an iron oxide-containing contrast medium in combination with high-resolution T2-weighted imaging].

AIM: To investigate superparamagnetic iron oxide (SPIO) particles as intravesically applied contrast material in combination with high-resolution T2-weighted MR imaging for the diagnostic assessment of urinary bladder tumors. METHODS: A prospective study was performed in 40 patients with suspected urinary bladder tumors who underwent MR imaging with a body phased-array coil at 1.5 T. Prior to imaging, a SPIO-containing solution (179.2 mg Fe/l) was instilled into the bladder. All patients were examined with T2-weighted, half-fourier acquired single shot turbo spin echo sequences and T1-weighted fast low angle shot sequences in 3 planes as well as a T2-weighted turbo spin echo sequence (TSE) using a 512 matrix. An additional gadolinium-enhanced dynamic study was performed in 33 patients. All patients underwent transurethral resection of the bladder or cystectomy. RESULTS: The combination of intravesically applied SPIO particles and a high-resolution T2-weighted TSE sequence depicted intravesical tumors as small as 4 mm. A reliable identification of the different layers of the bladder wall was possible in 5 cases only. The T2-weighted TSE sequence allowed the correct determination of the depth of infiltration in 29 of 36 patients with urothelial cancer by assessing the inner and outer boundary of the urinary bladder wall. This sequence had a diagnostic accuracy of 81% compared to 84% for the dynamic study (26/31). CONCLUSION: Even small tumors could be identified with the T2-weighted TSE sequence after intravesical administration of SPIO particles but it was not possible to reliably differentiate the layers of the bladder wall. The results suggest that a dynamic MR imaging study cannot be dispensed with in patients with urinary bladder cancer.

[Noninvasive and invasive bladder cancer: diagnostics and treatment].

Therapy of superficial bladder tumors is transurethral resection (TUR), and in cases of pT1 or high-grade tumors a re-TUR is indicated. Patients with carcinoma in situ receive intravesical chemotherapy or BCG for at least 3 months. Persistent carcinoma in situ may be treated by radical cystectomy. With the provision of a functionally adequate urinary diversion, cystectomy represents an effective treatment for patients with muscle-invasive bladder cancer without metastatic spread. Regional lymph node metastases can be found in up to 15% of stage T1 disease and are present in 33% of stage T3/4 lesions. Thus, lymphadenectomy gains diagnostic and possibly also therapeutic importance. For selected patients, who cannot be treated by radical cystectomy, multimodal concepts aiming to preserve the bladder are discussed. After or prior to cystectomy systemic chemotherapy may become necessary for some patients to positively affect the course of the disease in cases of locally advanced or metastatic lesions.

Intravesical bacillus Calmette-Guerin for superficial bladder cancer: experience with Danish 1331 strain.

A total of 95 patients with stage Ta/T1 superficial bladder cancer was eligible for intravesical bacillus Calmette-Guerin (BCG) immunoprophylaxis according to the standard high risk criteria for tumor recurrence and progression. Of these patients 50 agreed to undergo treatment while the remaining 45 refused any intravesical therapy and served as concurrent nonrandomized controls. The patient and tumor characteristics in the 2 groups of patients were identical. All patients underwent complete transurethral resection of the bladder tumor. Therapy consisted of 120 mg. weekly instillations of BCG (Danish 1331 strain) for 6 weeks. Among the 50 patients 33 received BCG initially while 17 received it after failure of intravesical chemotherapy. Responses were evaluated according to standard criteria. Recurrence was noted in 24 patients (48%) in the BCG group compared to 38 (84.4%) in the control group. The recurrence rates per year and per 100 patient-months were significantly reduced in the BCG arm compared to the control arm. The mean interval to first recurrence and the mean recurrence interval were significantly increased in the BCG arm compared to the control arm. The relative risk of recurrence in the BCG group was 0.62 versus 1.63 in the control group. Subgroup analysis showed significant benefit of BCG for patients with single as well as multiple, stages Ta and T1, and grades II and III tumors. Comparison with pretreatment controls in the BCG group revealed a significant reduction in the recurrence rate in those patients after treatment with BCG, which was not seen in the control group. The benefit of BCG was seen in those who received BCG initially as well as in those who received it after failure of intravesical chemotherapy. Multivariate analysis of prognostic factors showed that this benefit in the BCG group was related only to the treatment, while other prognostic parameters, such as tumor stage, grade, number and so forth were not independent prognostic variables. The rate of progression to muscle invasion was not significantly different in the 2 treatment groups. The relapse-free survival in the BCG group was 35.4% at 60 months compared to 11.2% in the control group (p < 0.001). The side effects of BCG therapy were mild, brief and easily controlled with conservative measures.

Safety of transurethral surgery in the early postoperative period following an open cardiac procedure.

A retrospective investigation was performed to determine whether patients undergoing transurethral surgery soon after cardiac surgery experienced increased morbidity or mortality rates. From 1986 to 1990, 24 patients first underwent open heart surgery and then either transurethral prostatectomy, bladder tumor resection or bladder cup biopsy during the same hospital stay. Postoperative complications included significant hematuria in 2 patients (8%), mild stress incontinence in 1 (4%) and bladder perforation in 1. One patient died of a spontaneous pneumothorax 17 days after the urological operation. None of these patients had had a previous myocardial infarction. The outcome of these patients was compared to that of 115 men who underwent transurethral prostatectomy for presumed benign disease during 1990. Complications of transurethral prostatectomy in this group included significant gross hematuria in 5 men, while 6 experienced urinary retention (1), atrial fibrillation (1), delirium (1), myocardial infarction (1), seizure (1) and intraoperative urethral injury (1). There was 1 death from multiple postoperative complications. Morbidity and mortality rates did not differ significantly between the 2 groups. Transurethral surgery performed after cardiac surgery during the same hospital stay appears to be safe, provided the patient is stable.

Bladder cancer: analysis of multi-detector row helical CT enhancement pattern and accuracy in tumor detection and perivesical staging.

PURPOSE: To evaluate the enhancement pattern of bladder cancer and the accuracy of multi-detector row helical computed tomography (CT) in the detection and staging of bladder cancer. MATERIALS AND METHODS: In 20 patients, the attenuation value of bladder cancer was measured on dynamic contrast material-enhanced multiphasic CT images obtained with scanning delays of 40, 60, 80, and 100 seconds. In 67 patients, CT data were obtained with a 60-second scanning delay that covered the bladder (section thickness, 2.5 mm; beam pitch, 1.5) and a 180-second scanning delay that covered the abdomen (section thickness, 5 mm; beam pitch, 1.5). We prospectively evaluated CT images and compared findings at CT with findings at histologic examination. We evaluated cancer detection rate, positive predictive value of cancer detection, and sensitivity and specificity in the diagnosis of perivesical invasion. RESULTS: The attenuation value of bladder cancers was significantly higher on 60- (105 HU +/- 16) and 80-second (97 HU +/- 15) delayed CT images than on the other images (P <.05). The cancer detection rate and positive predictive value for cancer detection were 97% and 95%, respectively, in 67 patients and increased to 100% and 100%, respectively, in 44 patients with a time interval of 7 or more days between transurethral resection of the bladder (TURB) and CT examination. Sensitivity and specificity in the diagnosis of perivesical invasion were 89% and 95%, respectively, in 67 patients and increased to 92% and 98%, respectively, in 44 patients with a time interval of 7 or more days between TURB and CT examination. CONCLUSION: Bladder cancer tends to show peak enhancement with the 60-second scanning delay. Multi-detector row helical CT is useful in the detection and staging of bladder cancer.

[Bladder cancer in patients over 80 years old].

We studied 86 patients with bladder cancer who were 80 years old and over. All were studied at the time of their first presentation for treatment in our hospital. About 40% of then were somewhat limited in performing usual daily activities before the first treatment, and they could not come to the hospital by themselves. Tumors in patients were larger, of higher grade and more invasive than those in younger patients. Transurethral resection of the bladder tumor (TUR-Bt) was done in 94% of patients with a superficial tumor and in 56% of those an invasive tumor. The recurrence rates after TUR-Bt for superficial tumor were 48%, 64% and 89% in 1 year, 3 years and 5 years, respectively. Recurrence rates were significantly different in younger patients. Overall cancer related survival rates were 86%, 60%, and 56% in 1 year, 3 years and 5 years, respectively. The outcome were significantly worse in patients over 80 years old than in those under 79 years old. To improve the outcome of treatment for bladder cancer in patients over 80 years old, cooperation among doctors, patients and families was important.

[Results of therapy in different groups of risk for superficial bladder cancer].

Approximately 10.0% of tumors occurs in the lower urinary tract and morbidity and lethality are constantly on the rise. Over 90% of such tumors registered in Europe and the USA is transitional cell carcinoma. Primary bladder cancer morbidity in Russian males rose by 4.0-4.6% in 1990-1997 while the share of patients with superficial bladder cancer (SBC) went up by 1.5% for the same period. According to the National Bladder Cancer Group, the rising incidence of relapsing SBC is associated with urothelial dysplasia, positive test for urinary sediment after therapy and occurrence of four or more tumors larger than 5 cm. Prevention of muscular invasion is vital in management of SBC. Sometimes, such aggressive modalities as early cystectomy or radiotherapy are recommended in cases of high risk for this pathology. Conversely, certain palliative measures, short of transurethral resection of the bladder and adjuvant intravesical therapy, are regarded as sufficient.

Whole bladder wall photodynamic therapy for refractory carcinoma in situ of the bladder.

Whole bladder wall photodynamic therapy (PDT) with haematoporphyrin derivative and an argon dye laser as a light source was performed on 34 patients with refractory carcinoma in situ (CIS) of the bladder. Twenty-five of the 34 patients (73.5%) had achieved a complete response (CR) at 3 months after the treatment. The median follow-up for these CR patients is 49.3 months. Although recurrence within 2 years of follow-up occurred in 14 (77.8%) of the 18 CR patients followed to that point, since most of the recurrent tumours were superficial and low-grade papillary tumours, transurethral resection of the bladder tumours appeared to be sufficient. Of the total of 34 patients, ten were alive with bladder intact with a mean follow-up period of 64.0 months. Skin photosensitivity and transient decrease in bladder capacity were noted as adverse reactions, caused by retention of haematoporphyrin derivative in the skin and normal portion of the bladder. These data suggest that PDT can be an effective form of therapy for CIS of the bladder.
