We report a patient whose irritable bladder symptoms following Bacillus Calmette Guerin (BCG) instillation were satisfactorily treated by steroid administration. A 59-year-old male had undergone transurethral resection for the bladder carcinoma recurred three times. The histopathological examination revealed the tumor as transitional cell carcinoma, G1 to G2, and pTa. Subsequently an instillation of 80 mg BCG into the bladder was planned 8 times every 7 days. After the 5th instillation he presented with gross hematuria, painful micturition, pollakisuria, urgency and reduced bladder capacity of 15 ml. The dose was reduced to 40 mg and another 3 instillations were accomplished. Since conventional treatments of anti-cholinergics, analgesics and epidural anesthesia were of little help for the subjective symptoms, he was put on the steroid pulse therapy 2 weeks after completion of the BCG regimen. The treatment gradually improved the subjective symptoms and increased the bladder capacity up to 160 ml. In conclusion, we believe that the steroid pulse therapy deserves considering in the early stage of irritable bladder symptoms following BCG instillation. 相似文献

A 61-year-old man was referred to our hospital due to positive urine cytology. He underwent multiple cold punch biopsies of the bladder and the histopathological finding was transitional cell carcinoma (TCC), carcinoma in situ (CIS), grade 3. He was treated with 121.5 mg of bacillus Calmette-Guérin (BCG) (Connaught strain) suspended in 50 ml of saline instilled into the bladder at weekly intervals. After the third instillation he developed a fever up to 39 degrees C, pain on urination and an elevation of liver enzymes. Antituberculous drugs were administered and he was re-admitted for further evaluation. The chest radiograph showed diffuse extensive bilateral lung densities. His chest computed tomographic (CT) scan showed bilateral interstitial pneumonitis. All cultures from his blood, urine, sputum, and bronchoalveolar lavage remained negative for mycobacteria. He was diagnosed as having a hypersensitivity reaction of bilateral lung after immunotherapy with BCG. Pulse steroid therapy was done. The chest radiograph, findings improved and he was clinically asymptomatic after steroid therapy. 相似文献

A 49-year man, with past history of right total nephroureterectomy due to urothelial carcinoma of the right renal pelvis in September 2006 and left partial ureterectomy due to contralateral ureteral recurrence in October 2007, underwent TUR-BT due to superficial high-grade recurrent bladder cancer. After TUR-Bt, he was treated with intravesical Bacillus Calmette-Guérin (BCG) instillation at weekly intervals. Just after 5th instillation, he suffered a continuous high fever up to 38 degrees C and complained of general fatigue. Chest CT showed diffuse micronodular shadows in both lungs, and serum liver enzyme was markedly elevated. All cultures from his sputum and urine were negative for mycobacterium tuberculosis. TB-PCR test and quantiferon were also negative. These findings together with no improvement of the symptoms with anti-tuberculous treatment finally made us to judge that this was due to a hypersensitivity reaction to BCG. Soon after pulse steroid therapy, body temperature was normalized and the abnormal findings of the lung and liver disappeared. 相似文献

Clinical outcome of conservative therapy for stage T1, grade 3 transitional cell carcinoma of the bladder 总被引:10,自引:0,他引:10
ISAO HARA HIDEAKI MIYAKE YOSHIZUMI TAKECHI HIROSHI ETO AKINOBU GOTOH MASATO FUJISAWA HIROSHI OKADA SOICHI ARAKAWA SADAO KAMIDONO KOBE UROGENITAL TUMOR STUDY GROUP 《International journal of urology》2003,10(1):19-24
BACKGROUND: The objective of this study was to retrospectively investigate the effectiveness of transurethral resection of bladder tumor (TURBT) and intravesical instillation therapy for stage T1, grade 3 (T1G3) transitional cell carcinoma (TCC) of the urinary bladder. METHODS: Between January 1995 and December 1997, 97 patients with T1G3 TCC of the urinary bladder were treated by TURBT and adjuvant intravesical instillation with bacillus Calmette-Guérin (BCG) or other anticancer agents. The recurrence-free survival rates were evaluated according to several clinicopathological factors. The cases that progressed to muscle invasive disease were also analysed. RESULTS: In this series, the median follow-up period was 25 months (range, 5- 41) after the initial TURBT. Intravesical recurrence was noted in 44 patients (45%), and the 1, 2, and 3 year recurrence-free survival rates were 72%, 58%, and 42%, respectively. Multivariate analyses revealed that the risk of intravesical recurrence was significantly higher for patients who did not receive BCG therapy, irrespective of age, gender, tumor size, multiplicity, pathological stage, concomitant carcinoma in situ, and lymphovascular involvement. Moreover, after a median of 10 months, disease progression occurred in seven patients (7%), of which only one patient was treated by BCG therapy after initial TURBT. CONCLUSION: These findings suggest that intravesical instillation with BCG combined with TURBT is an effective conservative treatment for T1G3 TCC of the bladder. Patients with negative prognostic factors should be treated by BCG rather than other anticancer agents after TURBT. 相似文献

OBJECTIVES: The aim of this study is to evaluate the efficacy and safety of intrarenal bacillus Calmette-Guérin (BCG) instillation as a treatment for transitional cell carcinoma in situ (CIS) of the upper urinary tract. METHODS: Diagnostic criteria of upper urinary tract CIS were (1) positive urinary cytology, (2) negative multiple random biopsy of the bladder and prostatic urethra, (3) negative radiographic findings in the upper urinary tract and (4) two serial positive cytologies in selective ipsilateral urine sampling from the pyeloureteral system. Eleven patients diagnosed as having upper urinary tract CIS were enrolled in this study. Thus, 11 renal units were treated with BCG instillation. After placing a 6-french Double-J stent, BCG (80 mg) in 40 ml saline was instilled into the bladder weekly, 6 times in total as one course. RESULTS: At the end of one course, 9 cases showed negative urinary cytology. Among these 9 cases, 2 showed recurrence in the upper urinary tract after 4 months and 8 months of disease-free interval, respectively. These 2 cases have received an additional course of BCG instillation, but the urinary cytology did not normalize. Mean recurrence-free time was 19.6 months. Of the other 7 cases who responded to the first course of instillation, 6 cases were alive with no evidence of the disease. The remaining patient died of rectal cancer with no evidence of transitional cell carcinoma (TCC). Of the 2 cases who showed positive urinary cytology even after the first course, 1 underwent nephroureterectomy. The other case was diagnosed as having malignant lymphoma 3 months after the end of this instillation therapy, and he died of malignant lymphoma. As side effects, 8 cases (72.7%) showed bladder irritability, and 4 presented fever higher than 38 degrees C. However, no patient needed antitubercular treatment. CONCLUSION: As for the short-term response, BCG instillation for the treatment of upper urinary tract CIS is considered to be effective and safe. Longer follow-up and further experience with this treatment are required. 相似文献

We report 3 cases of prostatic involvement of transitional cell carcinomas (TCCs). All cases presented positive urinary cytology after intravesical instillation of Bacillus Calmette-Guerin (BCG) and then random biopsy of bladder and transurethral resection (TUR)-biopsy of prostatic urethra were performed. TUR-biopsy demonstrated TCC in the prostate, although random biopsy failed to detect tumors in the bladder in all cases. Case 1 was treated with cystourethrectomy with ileal conduit, case 2 was treated with cystourethrectomy with bilateral ureterocutaneostomy and case 3 was treated with cystectomy with orthotopic ileal neobladder reconstruction. All cases are alive with no evidence of disease. TUR-biopsy of prostatic urethra should be perfomed when patients present positive urinary cytology after BCG instillation therapy, because prostatic involvement of TCC associated with bladder carcinoma in situ is not rare. 相似文献

A 72-year-old female patient was diagnosed as having a tumor in her bladder at the department of obstetrics and gynecology. Transurethral resection of bladder tumor was performed in November, 2002. Pathology showed transitional cell carcinoma (TCC), G2>G3, pT1. Chemotherapy consisting of methotrexate, adriamycin and cisplatin and bladder instillation of Bacillus Calmette-Guerin (BCG) was performed. Re-biopsy revealed transitional cell carcinoma, G2, carcinoma in situ of the bladder and she received radical cystectomy with ureterocutaneostomy in June, 2003. After the cystectomy, the left ureter showed signs of cancer so BCG was administered through the left ureterocutaneostomy. During the second instillation, she had a high temperature and also exhibited signs of chills with frequent shivering followed by dyspnea, severe hypotension and tachycardia. We started the patient on dopamine and norepinephrine drips to maintain blood pressure and then started isoniazide and meropenem for presumed septic shock. The next day, the patient continued to be febrile and her condition deteriorated. After she was given endotoxin absorption therapy, she regained normal blood pressure and her heart rate, but was still febrile. After 13 days, rifampicin, ethambutol, and pyrazinamide were administered and after 18 days predonisolone was begun. From that point the patient's general condition gradually improved. 相似文献

At present, patients with lower urinary tract symptoms, including storage symptoms, caused by prostatic disease are predominantly treated with alpha1-adrenoceptor antagonist and anticholinergic agents. However, some patients are not improved by this treatment. We investigated the efficacy of Goshajinkigan in 25 patients with prostatic disease in whom pollakisuria was not improved by treatment with drugs for lower urinary tract symptoms. The urinary frequency was significantly improved both in the daytime and at night. The parameters of uroflowmetry, the residual urine volume, the international prostate symptom score and QOL score were also improved after therapy. It was considered that the pollakisuria was improved by Goshajinkigan induced activation of spinal kappa-opioid receptors, which inhibited the micturition reflex via blunting of bladder sensation. The inhibition of C-fiber and the down regulation of Fos protein in the pontine micturition center were also suggested to be related with improvement ofpollakisuria. Chinese herbal medicine therapy is different in various aspects from Western medicine. Clarification of the mechanisms of Chinese herbal medicine and Sho (patient status in Chinese herbal medicine) is awaited. 相似文献

Twelve patients with superficial bladder cancer and carcinoma in situ of the bladder were treated with intravesically instilled BCG solution. As suggested by Pagano's group, we used BCG in a lower dose than usual hitherto (75 mg, strain Pasteur Paris). Complete tumor remission was obtained in all patients except the two whose treatment had to be discontinued at an early stage because of severe side effects. None of our patients was free of symptoms; pain or micturition, pollakiuria, gross hematuria, fever, swollen lymph nodes, and epididymitis occurred. We think, therefore, that low-dose therapy with BCG is as effective as full-dose therapy but the side effects are no less severe. 相似文献

A 67-year-old man presented with pollakisuria, and miction pain. The patient who had superficial bladder cancer was treated with transurethral resection and instillation of Pirarubicin hydrochloride. Urinalysis revealed a marked increase in eosinophilic cells. A cystoscopic examination revealed an ischemic lesion and hypervascular lesion throughout the bladder. Histological findings of biopsied bladder specimens showed eosinophilic cystitis. Bladder symptoms are improved with steroid administration. 相似文献

To examine the incidence of recurrence, progression and survival in patients with grade 3 superficial bladder cancer after transurethral resection (TUR) and adjuvant intravesical instillation of Bacillus Calmette-Guérin (BCG), we retrospectively studied 39 patients with grade 3 superficial bladder cancer. Nineteen patients with high-grade superficial bladder cancer (pTa, pT1) and 5 patients with grade 3 carcinoma in situ (CIS) received intravesical instillation of BCG after transurethral resection of the bladder tumor (BCG group and CIS-BCG group). The Tokyo 172 strain BCG was given for 8 weeks, as a rule, in a dose of 80 mg in 40 ml of saline instilled into the bladder. As a control, 15 patients with grade 3 superficial bladder cancer who did not receive BCG therapy after TUR were compared (non-BCG group). Of the BCG group (n=19), 4 patients (21.1%) had recurrent tumor and 3 had invasive progression after BCG therapy and died as a result of tumor progression, while in the non-BCG group (n=15), 8 cases (53.3%) developed recurrence, only one case had progression and died of cancer. In the CIS-BCG group (n=5), 3 patients (60.0%) had recurrent tumor and 2 had invasive progression. Univariate analysis (Logrank test) demonstrated that tumor size and adjuvant instillation of BCG were associated with tumor recurrence except for carcinoma in situ, but tumor progression and survival did not differ significantly. Our results suggest that BCG therapy prevents grade 3 superficial bladder cancer (pT1, pTa) recurrence. 相似文献

BACKGROUND: The objective of this study was to evaluate the efficacy of intrarenal bacillus Calmette-Guérin (BCG) instillation for the treatment of carcinoma in situ (CIS) of the upper urinary tract. METHODS: Sixteen patients who were diagnosed as having CIS of the upper urinary tract were treated with intrarenal BCG instillation. BCG (80 mg) in normal saline was administered once weekly, 6 times in total as one course through a percutaneous nephrostomy tube in 5 patients, and a retrograde ureteric catheterization using a Single-J or Double-J stent in 2 and 9 patients, respectively. RESULTS: During the median follow-up period of 30 months (range: 9-90 months), no patients died, and 13 patients remained cytologically negative in urine collected from the upper urinary tract after BCG treatment was completed. However, one of these 13 patients had CIS in the bladder and prostatic urethra 34 months after the BCG therapy and had to undergo radical cystectomy. The remaining 3 patients experienced recurrence in the upper urinary tract 4, 8, and 11 months after treatment, despite a favorable response to the initial BCG instillation. Of these 3 patients, one patient received an additional course of BCG therapy, while the remaining 2 underwent nephroureterectomy. Bladder irritability or a fever higher than 38 degrees C was observed in 12 or 9 patients, respectively; however, such side-effects were not clinically significant, and no patient received antitubercular treatment. CONCLUSION: Intrarenal instillation of BCG appears to be effective and safe for treatment of CIS of the upper urinary tract; however, further experience and longer follow-up studies of this treatment are required. 相似文献

INTRODUCTION: The treatment of T1G3 bladder cancer is still a controversial issue. Nowadays, intravesical bacillus Calmette-Guérin (BCG) instillation is considered to be the treatment of choice for patients with high-grade superficial bladder tumour after transurethral resection of all visible tumour. The aim of this retrospective study was to determine the effects and results of this approach, recurrence and progression rates in patients with T1G3 superficial bladder tumours. MATERIALS AND METHODS: 43 patients (28 male, 15 female; mean age 65.5 years, range 21-82) with T1G3 TCC (transitional cell carcinoma) bladder tumour underwent transurethral resection and subsequent intravesical BCG according to Morales protocol, in the period 1993-1998 at our institution. The mean follow-up period was 52.5 (range 30-96) months. RESULTS: After one or more initial courses of therapy, 33 patients were disease-free. Twelve patients (27.90%) had recurrent tumour after a median of 7 (range 3-46) months. After a second course of BCG treatment, 6 patients had no evidence of disease, 3 patients had progression and 3 had recurrence. Progression occurred in 7 (16.27%) patients after a median of 19 (range 3-43) months. Five patients underwent radical cystectomy and the remaining 2 underwent bladder-preserving therapies. Two patients died of TCC and 3 due to disease-unrelated conditions. CONCLUSION: Intravesical BCG instillation can be recommended as treatment modality for responders with T1G3 TCC bladder tumour. The benefit of the second course of intravesical BCG therapy has to be confirmed in further investigations. 相似文献

We describe a case of bilateral tuberculous epididymitis that occurred two weeks after intravesical Bacillus Calmette-Guerin (BCG) instillation. A 72-year-old man received transuretheral resection of bladder transitional cell carcinoma in November 2000. Although he had no recurrence for about 4 years, cystoscopy revealed small papillary tumors in the bladder in September 2004. A course of 8 weekly intravesical instillations of BCG was started. After the second BCG instillation (160 mg) he had bilateral painful scrotal swelling. Although he was administered isoniazid (INH) and rifampicin (RFP), scrotal swelling got worse. Right orchiectomy and left epididymectomy was performed in December 2004. Histological diagnosis was bilateral tuberculous epididymitis. Postoperatively, he was administered INH and RFP and had no recurrence for 3 months. 相似文献

OBJECTIVE: To analyse the efficacy and safety of bacillus Calmette-Guérin (BCG) perfusion treatment forcarcinoma in situ (CIS) of the upper urinary tract. PATIENTS AND METHODS: Six patients with cytologically diagnosed CIS of the upper urinary tract were treated by BCG instillation via retrograde catheterization using a 6 F ureteric catheter or an 8 F indwelling JJ ureteric stent between the ureter and bladder. BCG (Tokyo 172 strain, 80 mg in 100 mL normal saline) was instilled weekly for 4 or 8 weeks. The efficacy and safety of the treatment was assessed. RESULTS: The mean (range) follow-up was 22 (9-38) months; none of the patients died, and all were negative for cytology in urine collected from the upper urinary tracts. However, one patient had recurrent CIS in the prostatic urethra; the patient was treated by intravesical BCG instillation. In all patients, positive cytology became negative after one or two instillations of BCG. The ureter became stenotic in two patients. Although irritative symptoms occurred in all patients, such side-effects disappeared in a few months and were not clinically significant. CONCLUSION: In these six patients retrograde BCG instillation for CIS of the upper urinary tract was effective and safe. Based on the cytology results after only two BCG treatments, the dose or number of BCG instillations could possibly be reduced, but further study is needed. 相似文献

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. 相似文献

AIM: In order to clarify the initial step of the mechanism by which bacillus Calmette-Guérin (BCG) exhibits antitumor activity via the immune response induced in the bladder submucosa after intravesical BCG therapy for human bladder cancer, various cytokines secreted in the urine after BCG instillation were measured. METHODS: After transurethral resection of bladder cancer, a 6-week course of BCG instillation was performed. At the first and sixth weeks' dosings, spontaneously excreted urine was collected before and 4, 8, and 24 h after BCG instillation. The urinary cytokines were determined by Sandwich enzyme-linked immunosorbent assay using monoclonal antibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF), tumor necrosis factor (TNF)-alpha, granulocyte colony-stimulating factor (G-CSF), interleukin (IL)-1beta, IL-8, interferon (IFN)-gamma, and IL-12. RESULTS: After the BCG therapy, various cytokines, such as GM-CSF, TNF-alpha, G-CSF, IL-1beta, IL-8, IFN-gamma, and IL-12 were secreted, comprising the immune response cascade. The mean urinary excretions of GM-CSF and TNF-alpha 4 h after the sixth week's instillation were significantly higher than the pre-instillation levels. There were no significant increases in the urinary IFN-gamma or IL-12 levels between 4 and 24 h after the sixth week's instillation. The TNF-alpha level 4 h after the sixth week's instillation had a strong tendency towards the absence of recurrence, with a mean follow-up of 54.1 months. The Kaplan-Meier curve showed the 2, 5, and 10-year recurrence-free survival rates were 72.4%, 65.8%, and 56.4%, respectively. CONCLUSIONS: We suggested that the urinary levels of TNF-alpha might be essential in antitumor activity after BCG therapy and might play an important role in the prevention of bladder tumor recurrence. 相似文献

Intravesical instillation of bacillus Calmette-Guerin (BCG) is the first-line therapeutic option for flat carcinoma in situ (CIS) of the bladder. Intravesical BCG instillation has been demonstrated to cause granulomatous prostatitis. Bladder CIS often also is known to show prostatic stromal invasion. We report a case of BCG-induced granulomatous prostatitis and a case of prostatic stromal invasion of bladder CIS accompanied by locally advanced prostate cancer, which showed similar clinical findings after the intravesical BCG therapy. In these 2 patients, urinary symptoms such as dysuria were prolonged regardless of anti-tuberculous medication, hard nodules were palpable at the prostate, and hypoechoic lesions were visualized by transrectal ultrasound. Both patients were treated by transurethral resection of the prostate, and the diagnoses were made by histopathological examination. Urinary symptoms were resolved in both patients after surgery, but the prostatic stromal tumor showed recurrence of growth. We report the usefulness of transurethral resection of the prostate for medication-resistant BCG-induced granulomatous prostatitis, and the importance of the correct diagnosis of prostatic stromal invasion of bladder CIS especially in the cases with concurrent prostate cancer. 相似文献

BACKGROUND: Intravesical instillation of bacillus Calmette-Guerin (BCG) is efficient for prophylaxis of superficial bladder cancer and treatment for carcinoma in situ (CIS) of the upper urethelial cancer. However, the incidence of adverse effects is relatively high, and those include reactive arthritis. We retrospectively evaluated the incidence and the outcome of reactive arthritis following intravesical BCG therapy for urothelial cancers. PATIENTS AND METHODS: Intravesical instillations of BCC were performed in 192 cases (218 courses) between January 1998 and January 2002. BCG was instilled for prophylaxis of superficial bladder cancer recurrence in 170 (195 courses), treatment for CIS in 7 (8 course), and treatment for CIS in 7 (8 courses), and treatment for CIS in upper urinary tract in 15 (15 courses). RESULTS: Arthritis was recognized in 8 cases (3.7%, 8/218 courses), and 7 of them were identical to reactive arthritis following BCG therapy. Remaining 1 patient was diagnosed as rheumatoid arthritis (RA), and the relation between arthritis and intravesical BCG instillation was unclear. Mean number of BCG instillation was 5.6 (3-8 times). All reactive arthritis were occurred within 4 weeks after the last BCG instillation, i.e., BCG induced urinary tract infection, and 6 of them were polyarthritis. Concurrence of conjunctivitis was seen in one patient. HLA-B27 was negative in 4 examined patients. A nonsteroidal anti-inflammatory drug (NSAID) was used in all 8 patients, anti-tuberculous agents were used in 3, and prednisolone was added in 3, Arthritis was improved within 2 months in patients received prednisolone, however, it persisted longer than 3 months in patients without prednisolone. CONCLUSION: Arthritis was recognized in higher incidence than previous reports following intravesical instillation of BCG. All cases except one, diagnosed as RA, were diagnosed as reactive arthritis (Reiter's syndrome). However, correlation between HLA-B27 and arthritis was not clear in this study. Administration of steroidal drug was thought to improve arthritis in shorter duration. 相似文献
