Treatment of 300 patients with bladder cancer]

From September 1973 to September 1989, 300 patients with bladder cancer were treated at the Department of Urology, Hyogo College of Medicine. They were 231 males and 69 females with an average age of 65.3 years old. The overall 5-year survival rate (Kaplan-Meier's method) was 64.7%. The 5-year survival rates were not different between male patients and female patients, or between patients with single tumor and patients with multiple tumors. Patients with vesical irritation symptoms had more unfavorable prognosis than patients with painless hematuria. Size and configuration of the tumors also affected the prognosis. Histological diagnosis was transitional cell carcinoma in 291 patients, squamous cell carcinoma in 7 patients, adenocarcinoma in one patient and undifferentiated carcinoma in one patient. In patients with transitional cell carcinoma, the 5-year survival rates according to histological grades were 93.5% for G1, 77.8% for G2 and 31.6% for G3. The 5-year survival rate according to clinical stage was 94.4% for Ta, 79.7% for T1, 66.7% for Tis, 46.1% for T2, 38.5% for T3 and 26.6% for T4. Transurethral resection of bladder tumor (TUR-b.t.) was performed in 208 patients as an initial operation and the 5-year survival rate in these patients was 78.6%. The 5-year survival rates for total cystectomy (52 patients), partial cystectomy (6 patients) and simple tumor resection (4 patients) were 51.9%, 25.0% and 37.5%, respectively. These findings suggest that superficial tumors (Ta, T1) can be controlled with TUR-b.t. but infiltrating tumors (T2, T3, T4) should be treated more vigorously with multidisciplinary approaches.(ABSTRACT TRUNCATED AT 250 WORDS)     

Treatment of 46 cases of renal pelvic and ureteral tumors

During about 10 years from November, 1977 to March, 1987, 46 patients with renal pelvic and ureteral tumors were treated at the Department of Urology, Hamamatsu University School of Medicine and the affiliated hospitals. There were 34 males and 12 females with the highest age incidence in the seventies. Histologically, 44 transitional cell carcinomas and 2 squamous cell carcinomas were found. Of the 44 transitional cell carcinomas, 1 was Tis; 13 T1, 2 T2, 8 T3, 15 M+ (with metastatic lesion), and 5 TX. As to grading, 1 was G1; 24 G2, 15 G3, and 4 GX. Staging was correlated with grading. The 5-year survival rates (Kaplan-Meier's method) were 37% in patients with transitional cell carcinoma. Among patients with transitional cell carcinoma, the 5-year survival rate was 43% for G2 and 42% for G3. As to staging, the 5-year survival rates were 71% and 46% in patients with stage of T1 and T3, respectively. No patient with M+ survived longer than 4 years. The 5-year survival rates were 38% and 34% in renal pelvic tumors (24 cases) and ureteral tumors (20 cases), respectively. As to the treatments, the 5-year survival rates after curable treatment (24 cases) and non-curable treatment (20 cases) were 63% and 7%, respectively.     

Survival rate of bladder tumors--an analysis of 2304 patients with bladder tumors in the Tokai Urological Cancer Registry

During the 7 years from 1980 to 1986, 2860 cases of bladder tumors were registered in the Tokai Urological Cancer Registry. Among the 2860 cases, 2304 cases were selected from the registered cases for the present study. The 5-year relative (actual) survival rates were 73.8% (61.9%) of all patients; 48.9% (42.4%) in those with malignant neoplasma of urinary bladder excluding transitional cell carcinoma; 48.8% (41/3%) in those with mixed tumor. In patients with transitional cell carcinoma, the 5-year relative (actual survival rates were 93.7% (78.8%) for G1, 87.2% (74.1%) for G2 and 47.3% (38.9%) for G3. As to staging, the 5-year survival rates were 101.9% (88.0%), 87.6% (75.3%), 57.9% (47.8%), 33.7% (28.2%) and 6.1% (5.0%) in patients with stage of Ta, T1, T2, T3 and T4, respectively. The tumors with muscle infiltration and high grade malignancy obviously deteriorated patients' survival. The 5-year relative (actual) survival rate for patients treated with TUR was 98.1% (82.2%). As to grading, the 5-year survival rates were 102.2% (86.6%) for G1, 104.3% (88.3%) for G2 and 56.9% (48.3%) for G3. The 5-year survival rates of those with Ta, T1 and T2 were 103.9% (89.7%), 96.0% (82.6) and 61.1% (49.1%), respectively. The 5-year relative (actual) survival rate for patients undergoing total cystectomy was 62.4% (52.3%). In those patients, the 5-year survival rates were 96.7% (80.9%) for G1, 63.6% (55.7%) for G2 and 55.4% (47.1%) for G3. As to staging, the 5-year survival rates were 102.3% (90.6%), 77.8% (68.2%), 56.3% (47.9%), 41.8% (34.9%) and 15.2% (13.1%) in patients with stage of Ta, T1, T2, T3 and T4, respectively. The 3 and 5-year relative (actual) survival rates in patients with advanced bladder tumors were 5.3% (4.8%) and 0.87% (0.73%), respectively.     

Bladder carcinoma: therapeutic concept of the Urology Department of the University Hospital, Mainz]

A therapeutic concept based on tumor staging and grading is presented: T0N0M0 - urine cytology positive - cystoscopy every 3 months. Transitional cell carcinoma (90%): T(iS)N0M0 - carcinoma in situ - cystoscopic biopsy every 3 months. Cystectomy with commencing tumor infiltration. T1N0M0 (80% of all bladder tumors): T1N0M0G0 - TUR; cystoscopy every 3 months. T1N0M0G1-3 - TUR; control-TUR 6 weeks later with systematic biopsy. G3 with tumor recurrence - cystectomy. T2N0/N1M0; G1-2 - TUR; local chemotherapy (adriamycin). G3 - cystectomy; high voltage treatment in inoperable patients. T4NxMx - symptomatic-palliative therapy: TUR, urinary diversion. Squamous cell carcinoma (2-5%): as transitional cell carcinoma; with high voltage therapy adjuvant chemotherapy using bleomycine. Adenocarcinoma (2-3%): as transitional cell carcinoma; cystectomy including part of the anterior abdominal wall and umbilicus. Immunostaging (assessment of the immunocompetence) should be part of the diagnostic procedures and follow-up examination.     

The value of a second transurethral resection for T1 bladder cancer

OBJECTIVE: To evaluate a series of repeat transurethral resections (TURs) of tumour in patients with T1 bladder cancer, usually used to ensure a complete resection and to exclude the possibility muscle-invasive disease. PATIENTS AND METHODS: In all, 136 consecutive patients had a second TUR because of a histopathological diagnosis of T1 transitional cell carcinoma (TCC) after their initial TUR. Of the 136 patients, 101 were first presentations and 35 had recurrent tumours. The second TUR was done 4-6 weeks later. The evaluation included the presence of previously undetected residual tumour, changes to histopathological staging/grading, and tumour location. RESULTS: In all, 71 patients (52%) had residual disease according to findings from specimens obtained during the second TUR. The staging was: no tumour, 65 (48%); Ta, 11 (8%); T1, 32 (24%); Tis, 15 (11%); and > or = T2, 13 (10%). Histopathological changes that worsened the prognosis (>T1 and or concomitant Tis) were found in 21% of patients. Residual malignant tissue was found in the same location as the first TUR in 86% of the patients, and at different locations in 14%. Overall, 28 patients (21% of the original 136) had a radical cystectomy as a consequence of the second TUR findings. CONCLUSIONS: A routine second TUR should be advised in patients with T1 TCC of the bladder, to achieve a more complete tumour resection and to identify patients who should have a prompt cystectomy.     

Transurethral resection and intra-arterial chemotherapy for muscle-invasive bladder cancer

Thirty-three patients with muscle-infiltrating T2–T3a bladder carcinoma were treated by TUR through the full thickness of the bladder wall and extended into the perivesical fat. The solitary tumours were not more than 4 cm in diameter. Histology proved in every case tumour stages of pT2 (17 patients) or pT3a (16 patients), G2 or G3 transitional cell carcinoma and negative mucosal biopsies. After TUR the patients received 1 or 2 cycles of chemotherapy: 60 mg of doxorubicin, 50 mg of cisplatin, 1 g of 5-fluorouracil administered into the ipsilateral hypogastric artery. There was no perioperative mortality but one patient died of complications related to chemotherapy. During the first year of follow-up relapses of muscle-invasive cancer were observed in 3 patients (10%), two were subjected to cystectomy and one to repeated TUR. With a median follow-up of 34 months 27 patients are alive and have functional bladder. The actual 3-year and 5-year survival rates were 17/21 (81%) and 6/9 (67%), respectively. The results of this study suggest that in strictly selected patients extended TUR and intra-arterial chemotherapy may be a bladder-preserving treatment modality for muscle-invasive bladder cancer. Regular (three monthly cystoscopy, cytology, biopsy, CT) investigations and follow-up are necessary to detect recurrences.     

Cancer specific outcomes in patients with pT0 disease following radical cystectomy

PURPOSE: We assessed clinical outcomes in patients found to have no evidence of disease, ie pT0, in the cystectomy specimen following radical cystectomy for transitional cell carcinoma. MATERIALS AND METHODS: Between 1984 and 2003, 955 consecutive patients underwent bilateral pelvic lymphadenectomy and radical cystectomy for bladder cancer at 3 institutions, namely The Johns Hopkins Hospital, University of Texas Southwestern Medical Center and Baylor College of Medicine. Excluding nonTCC histology and patients with missing data resulted in 888 evaluable cases. Primary end points were recurrence-free survival and bladder cancer specific survival. RESULTS: Final pathological evaluation revealed absent transitional cell carcinoma in the cystectomy specimen, ie pT0, in 59 patients (7%), of whom 2 (3%) had pathologically positive lymph nodes. Transurethral resection stage or clinical stage data were available on 56 patients (95%), including Tis in 5 (9%), Ta in 2 (4%), T1 in 18 (32%), T2 in 29 (52%) and T3 in 2 (4%). Overall 6 recurrences (10%) were noted, including cTis in 1 case, cT1 in 1, cT2 in 3 and cT3 in 1. Median followup in patients with pT0 disease was 56 months (range 3 to 183). Three patients (5%) died of bladder cancer and another 4 (7%) died of other causes. Five and 10-year bladder cancer progression-free and cancer specific survival estimates in patients with pT0 disease were 90% and 81%, and 95% and 85%, respectively. CONCLUSIONS: Despite excellent clinical outcomes in the majority of patients with no evidence of tumor on final pathological evaluation not all patients with pT0 disease in the cystectomy specimen are cured of bladder cancer. These events may even occur in patients with nonmuscle invasive or muscle invasive organ confined pathology at staging transurethral resection. Further study is needed to identify prognostic factors in this population.     

TUR and adjuvant intravesical chemotherapy in T1G3 bladder tumors: recurrence, progression and survival in 137 selected patients followed up to 20 years

OBJECTIVES: To evaluate a highly selected population of patients affected by T1G3 bladder transitional cell carcinoma (TCCB) treated by transurethral resection (TUR) and adjuvant intravesical chemotherapy. MATERIALS AND METHODS: Between January 1976 and April 1999, 137 patients with T1G3 TCCB were treated by TUR plus intravesical chemotherapy. Particularly, a sequential combination of mitomycin C (MMC) and epirubicin (EPI) was adopted in 91 patients (66.4%). The main exclusion criteria were concomitant or previous Tis, previous T1G3 TCCB, tumor size greater than 3 centimeters and number of tumors more than 3. TUR was repeated if a superficial tumor recurred. Patients went off study if Tis, recurrent T1G3 or invasive tumor were detected during treatment or thereafter. Adjuvant therapy, recurrence and progression were considered in multivariate analysis regarding recurrence, progression and survival respectively. RESULTS: Observation period was up to 240 months with a minimum of 2 years in 112 patients (82%). Seventy patients (51%) recurred. The recurring tumor was again a T1G3 in 22 (16%) patients. Thirteen patients (9.5%) progressed. The 5-year progression-free survival rate was 90%. Median progression-free survival was 149 months. Twenty-two patients (16%) died, 9 (6.6%) of whom due to bladder cancer. Median overall survival was 155 months. The 3- and 5-year disease-free overall survival rates were 89% and 80% respectively. Ten cystectomies (7.3%) were performed. In conclusion, 123 patients (90%) maintained their intact bladder with a mean disease-free overall survival of 104 months. The sequential combination of MMC and EPI adjuvant therapy resulted more effective to be than single drug chemotherapy on recurrence rate (p=0.0021) but had no impact upon progression (p=0.127) and specific survival (p=0.163). Progression (p<0.001) after conservative treatment was the main prognostic factor for survival. CONCLUSION: A conservative approach is an appropriate therapeutic option for the initial management of selected T1G3 bladder tumors.     

Clinical statistics of the bladder tumor--clinical and pathological aspects of 325 cases

We analyzed 325 primary bladder tumor patients who were treated in our hospital during the past 15 years. There were 242 males and 83 females who were between 20 and 84 years old with an average age of 63 years old. The most frequent complaint was macroscopic hematuria in 76.9% of the patients (250/325). Cystoscopically, a single tumor was seen in 71%, the tumor was medium sized (1 to 3 cm) in 32%, and 56% were papillary tumors with a stalk. Histologically, 300 (92.3%) cases were transitional cell carcinoma. There were 42, 206 and 52 patients with grades 1, 2 and 3 transitional cell carcinoma and stage Tis, Ta, T1, T2, T3a, T3b, T2-4M1 and Tx were 2,46, 151, 30, 15, 16, 37 and 3 cases each. Transurethral resection was performed in 231 (71.1%), partial cystectomy in 6 (1.8%) and total cystectomy in 44 (12.5%) cases each.     

Prognosis of bladder tumor patients treated by TUR

One hundred and eleven cases of bladder tumors were treated with transurethral resection (TUR) and transurethral electrocoagulation as the initial treatment from 1974 and 1983. Eighty nine cases were male and 22 cases were female. The average age was 60.1 years old. Of the 111 patients, 57, 33, 2, 1 and 15 patients had a tumor of Ta, T1, T2, T3a and Tx respectively. The number of grades G0, G1, G2, G3, GX cases was 1, 38, 40, 17, 12, respectively. Other than these, 2 cases of squamous cell carcinoma and 1 of adenocarcinoma were included. The actual survival rates for 5 years in Ta and T1 were 84.4 and 88.9% respectively, and the relative survival rates were 99.5 and 109.1%. TUR was recommended for superficial bladder tumor because of good prognosis. The 5-year recurrence rates for single tumors with and without prophylactic bladder instillation were 21.4 and 27.5% respectively, and those for multiple bladder tumors were 58.6 and 51.8%. There was no significant difference between the group with and without bladder instillation.     

Clinical analysis of bladder cancer

PURPOSE: We report our clinical experiences of treatment for bladder cancer. MATERIAL AND METHODS: Clinical analysis was performed about 282 primary bladder cancer patients who performed first time treatment in our hospital from January 1991 to December 2002. RESULTS: As to T classification, 127 patients were in Ta, 89 in T1, 27 in T2,18 in T3, eight in T4 and 13 in Tis, respectively and among those, there were seven patients with a metastasis. Most patients of superficial cancer were treated by combined use of TUR and instillation therapy. There were few patients of total cystectomy performed as a first time treatment in the case of invasive cancer in our clinic and comparatively many preservation therapies by TUR, systemic chemotherapy and radiotherapy combined use were performed. Cancer recurred to 90 cases in 275 patients, and 18 patients died owing to cancer progression. Five and ten-years-recurrence free rate in the whole were 59.5 and 44.3%, five and ten-years-disease specific survival rate were 92.9 and 85.9%. Furthermore, 5-years-disease specific survival rate classified by T stage were 100, 100, 71.2, 46.7 (3-years-survival), 53.6, 83.3% in Ta, T1, T2, T3, T4, Tis, respectively and the significant difference was observed. The disease specific five-years survival rate of the whole local invasive carcinoma (T2-4N0M0) was 57.5% and 70.2% in the case of preservation therapy performed by TUR, chemotherapy and radiotherapy combined use. CONCLUSIONS: An appropriate treatment according to the each case is needed for bladder cancer.     

A clinical investigation on renal pelvic and ureteral tumors

The 60 cases of primary renal pelvic and ureteral tumors treated at Mie University hospitals between January 1977 and December 1987 were reviewed and factors predicting the prognosis were investigated. The patients consisted of 47 men and 13 women (3.6: 1.0). Their ages ranged from 38 to 82 years with a mean of 65.2 years. According to Akaza's category classification of the ureteropelvic tumor, 42 cases were classified to category A, 15 cases category B and 1 case was classified to category C. Histologically, 59 transitional cell carcinomas and 1 squamous cell carcinoma were found. As to grading, 5 was G1, 31 G2, 21 G3 and 2 GX. As to staging, 20 were pT1, 10 pT2, 21 pT3, 3 pT4 and 6 pTX. Staging was correlated well with grading. Total nephroureterectomy with bladder cuff was performed on 39 patients and the other surgical treatments were done on 15 patients. Recurrence of the bladder tumor was found in 22.4%. The 5-year survival rate (Kaplan-Meier's method) was 47.8% for all of the patients. Among the patients with transitional cell carcinoma, the 5-year survival rate was 100% for G1, 57.6% for G2 and 28.6% for G3. As to staging the 5-year survival rate was 90.0% for below pT1, 20.0% for pT2 and 41.1% for pT3. The results from the present study suggest the prognosis is decided by grade and stage in pelvic and ureteral tumors, and it is wanted to develop a system of postoperative adjuvant therapy.     

Initial conservative treatment for grade 3 Ta-1 superficial bladder cancer

We retrospectively investigated the therapeutic outcomes of our series of 7 Ta and 62 T1 bladder cancers with grade 3 (G3) malignancy in 61 men and 8 women having a mean age of 66.2 years. Following transurethral resection of bladder tumor (TURBT), 35 and 6 patients received intravesical instillations of bacillus Calmette-Guerin (BCG) and anthracycline-derivants, respectively, whereas 15 received no adjuvant therapy. Five and 2 patients received systemic and local chemotherapy with irradiation, respectively, and six underwent radical cystectomy for invasive potential. The 5-year nonrecurrence, progression-free, and overall (cancer-specific) survival rates were 66, 82%, and 76 (88%), respectively, after a median follow-up of 52 months. The 5-year non-recurrence rates were 24% in non-adjuvant, 85% in BCG, 0% in anthracycline-derivants, 65% in systemic and local chemoradiation therapy, and 68% in cystectomy. The 5-year progression-free and overall (cancer-specific) survival rates of the patients treated with BCG instillation were 91% and 94 (100)%. There were no significant differences in the 5-year non-recurrence and progression-free rates between 12 patients with carcinoma in situ (CIS) and 23 patients without CIS. Complete TUR of all visible tumors and a reliable histopathological diagnosis of appropriate specimens bearing the muscle layer are mandatory for assessment of recurrence. G3 Ta-1 bladder cancers and CIS showed a high risk of recurrence, and required aggressive treatment. Since BCG therapy following TURBT significantly reduced the risk of recurrence and progression, adjuvant BCG therapy is considered to be the most promising initial conservative treatment for G3 Ta-1 bladder cancers.     

Therapy of superficial bladder carcinomas

Treatment of superficial bladder carcinoma was derived by several large randomized trials. This group of cancers is stratified by differentiation grade and stage in three groups of different risk profiles (Ta G1-2 vs. T1 G1-2 vs. Tis/T1 G3). Standard therapy is fractionated transurethral resection (TUR). Adjuvant therapy after transurethral resection is not indicated in primary Ta G1-2 tumors because there is a low recurrence rate and no risk of tumor progression. The recurrence rate can be decreased up to 15% in recurrent Ta or T1 G1-2 tumors by intravesical therapy with mitomycin C (20 mg/instillation) or adriamycin (50 mg/instillation). Therapy should be limited to early (within 24 h post-TUR) and short-term treatment (4 x weekly, 5 x monthly). Alternatively, patients can be treated by intravesical BCG (strain Connaught or strain RIVM). Maintenance therapy is advantageous according to recurrence rate. Tumors with great malignant ability (Tis or T1 G3) will be treated initially with adjuvant BCG. Patients who fail are candidates for radical cystectomy within 3-6 months after initial diagnosis. There is no need - except in clinical trials - for the administration of unverified or not admitted drugs. Copyright Copyright 1999 S. Karger AG, Basel     

Cystectomy in patients with high risk superficial bladder tumors who fail intravesical BCG therapy: pre-cystectomy prostate involvement as a prognostic factor

PURPOSE: To review understaging and outcome of patients who underwent radical cystectomy (RC) for high risk superficial bladder cancer after bacillus Calmette-Guérin (BCG) failure. PATIENTS AND METHODS: We carried out a retrospective study of 62 cases in which RC was indicated for clinical stage Tis, Ta, T1 transitional cell bladder tumors that failed transurethral resection (TUR) and BCG treatment. We used BCG (81 mg/Connaught BCG) in patients with superficial grade 3 tumors and CIS. We considered BCG failure a high-grade recurrence at 3 months of the first BCG course or after 2 courses. RC indications, correlation between their clinical and pathological stage and the ensuing progress were analyzed. We assessed the existence of any pre-cystectomy clinical or pathological factor related to understaging and survival. RESULTS: RC was performed in 22 patients with carcinoma in situ (CIS) (35%), 7 with Ta (11,2%), 31 with T1 (50%), and 2 with Tx tumors (3%). All 62 but one were high-grade tumors (grade 3 and/or CIS). Tumor was clinically understaged with stages pT2 or greater on the RC specimen in 17 patients (27%). The presence of tumor in the prostatic urethra at the moment of endoscopic staging before RC was the only factor associated with clinical understaging (p=0.003) and shorter survival (p<0.0002). Five-year disease-specific survival rate was significantly lower in understaged (38%) as compared with not-understaged patients (90%) after a median follow-up of 40-months (range 1-142) (p=0.006). Overall five-year disease-specific survival was 79%. CONCLUSIONS: RC should be performed prior to progression in high risk superficial tumors that fail after TUR and BCG. In patients with clinical and pathological nonmuscle invasive disease, RC provides an excellent disease-free survival. One third of patients with HRSBT who underwent RC after BCG failure were understaged and had a shorter survival. Tumor in the prostatic urethra at endoscopic staging was the only factor associated to understaging and shorter survival.     

Significance of random bladder biopsies in superficial bladder cancer

OBJECTIVES: We investigated to what extent biopsies of normal-appearing urothelium taken from patients with superficial bladder cancer (Ta, T1, Tis) showed malignant disease and whether those findings had impact on therapeutical decisions. PATIENTS AND METHODS: 1033 consecutive patients presenting with Ta, T1 or Tis (carcinoma in situ) superficial bladder tumors at increased risk for recurrence underwent multiple random biopsies from normal-appearing urothelium during transurethral resection (TUR). Patients with small, primary, singular tumors (smaller or equal to 1cm) were excluded from random biopsies. RESULTS: No tumor was found in the random biopsies of 905 patients (87.6%). 128 patients (12.4%) showed urothelial bladder cancer in their random biopsies (Tis: 74, Ta: 41, T1: 12, T2: 1). In 14 patients, where transurethral resection of the primary tumor revealed no signs of malignancy, urothelial bladder cancer was detected in the random biopsy material: Ta 8 patients, Tis 5 patients and T1 one patient. 21 patients with Ta tumors and 29 patients with T1 disease showed concomitant Tis. Upstaging of the primary, resected tumor by histological examination of the random biopsy material occurred in 75 patients (7%). Altogether, due to the random biopsy results therapy was altered in 70 patients (6.8%) of our series: It changed intravesical chemotherapy to BCG in 45, provoked a second TUR in 48 and cystectomy in 15 patients. CONCLUSIONS: While the clinical significance of random biopsies is still controversial, random biopsy results had strong impact on therapeutical decisions in our series. Regarding random bladder biopsies a simple tool for the urologist to identify high risk groups of patients, we recommend them as part of the routine management of superficial bladder cancer.     

Recurrence and progression in stage T1G3 bladder tumour with intravesical bacille Calmette-Guérin (Danish 1331 strain)

OBJECTIVE: To report recurrence and progression rates in patients with T1G3 superficial bladder carcinoma treated with intravesical bacille Calmette-Guérin (BCG, Danish 1331 strain) after complete transurethral resection. PATIENTS AND METHODS: Data from the records of 111 patients with T1G3 bladder carcinoma treated between January 1991 and December 1999 were analysed for recurrence, progression, salvage therapy and survival. RESULTS: Of the 111 patients with T1G3 bladder tumours, 69 had intravesical BCG therapy, 20 radical cystectomy and 22 only transurethral resection (TUR). Of the 69 patients receiving BCG therapy 37 (54%) had no recurrence, and 24 (35%) had a recurrence that was not muscle-invasive (Ta/T1) and were treated with TUR only. The remaining eight (12%) progressed to muscle invasion and had salvage cystectomy. During the follow-up six patients died, four from disease and three from other causes, while the remaining 63 are alive and well. Of the other 42 patients, 15 are alive after radical cystectomy and 18 after TUR. CONCLUSION: This series further confirms the benefits of intravesical BCG (Danish 1331) in an adjuvant setting; furthermore, this treatment facilitates bladder preservation by reducing recurrences and delaying the progression in many patients.     

Radical transurethral resection and chemotherapy in the treatment of muscle-invasive bladder cancer: a long-term follow-up

OBJECTIVE: To evaluate the treatment of patients with muscle-invasive bladder cancer (T2-T4a) by radical transurethral resection (TUR) and cisplatin-methotrexate systemic chemotherapy. PATIENTS AND METHODS: Fifty patients with transitional cell carcinoma (TCC) of the bladder (nine T2, 36 T3 and five T4a) were treated by 'complete' TUR of the bladder tumour followed by 2-6 cycles of cisplatin (70 mg/m2) and methotrexate (40 mg/m2) chemotherapy. The median (range) tumour size was 3 (1-7 cm). In six patients, attempted TUR at the dome of the bladder led to intraperitoneal perforation; the tumour was excised by partial cystectomy in these patients. The latest follow-up results from 57 patients treated by radical TUR and methotrexate alone, reported previously, are included. RESULTS: At the first evaluation cystoscopy immediately after completing chemotherapy, 38 patients were tumour-free, eight had persistent muscle-invasive TCC and four had Ta, T1+CIS disease. With an overall median follow-up of 47 months, 10 additional patients relapsed with muscle-invasive carcinoma in the bladder after a median interval of 15.6 months; three patients developed Ta, T1 tumours, three Ta, T1 + CIS, and six CIS only. Six of the 10 recurrent invasive tumours were at the same site, but four were at a different site in the bladder. Although during follow-up 12 patients developed superficial recurrence that required endoscopic treatment, the bladder was preserved (free of muscle-invasive cancer) in 37 of 50 patients. In 30 of these 37, this was achieved with no need for salvage radiotherapy or cystectomy. Six patients died from metastatic TCC with no tumour in the bladder. CONCLUSION: In this selected group of patients, muscle-invasive bladder cancer was controlled by TUR and systemic chemotherapy, preserving normal bladder function in 60% of patients without apparently comprising overall survival.     

Recurrence, progression and survival in bladder cancer. A retrospective analysis of 232 patients with greater than or equal to 5-year follow-up

A retrospective study of 232 bladder tumours with minimum follow-up 5 years is presented. The carcinoma was superficial in 66%, muscle-invasive in 31% and could not be staged in 3%. Primary treatment was mainly transurethral resection for superficial tumour, but was cystectomy or radiotherapy in 22 of 29 T1 G3. Of the superficial tumours, 71% recurred. Progression to higher T stage occurred in 15% of Ta and 29% of T1 tumours, and half of these patients died of bladder cancer. The corrected 5-year survival rates in grades 1, 2A, 2B and 3-4 were 96, 84, 64 and 43%, and in stages Ta, T1, T2 and T3 they were 94, 69, 40 and 31%. All patients with T4 tumour died within 4 years. Among the 45 patients with 40 Gy irradiation + cystectomy, the corrected 5-year survival rate was 83% in superficial and 64% in muscle-invasive tumours, and among the 38 with radical radiotherapy the rates in T1-3 were 46, 36 and 13%. Transurethral resection was successful in most Ta cases. Most T1 tumours were, like T2-4, of higher grade than Ta. Prognosis was worse in T1 than in Ta. After progression to muscle-invasive disease, even during close follow-up the outlook was poor, as poor as for patients with primary muscle-invasive disease.     

5-aminolaevulinic acid-induced fluorescence cystoscopy during transurethral resection reduces the risk of recurrence in stage Ta/T1 bladder cancer

OBJECTIVE: To assess the influence of 5-aminolaevulinic acid-induced fluorescence cystoscopy (FC) during transurethral resection (TUR) on the recurrence rate and the length of tumour-free interval in stage Ta/T1 transitional cell carcinoma (TCC) of the urinary bladder. PATIENTS AND METHODS: In all, 122 patients with primary or recurrent stage Ta/T1 bladder TCC treated with TUR were enrolled in a prospective randomized study. In group A the TUR was performed with standard white-light endoscopy, and in group B with FC. The patients were followed using standard cystoscopy and urinary cytology. The recurrence-free interval was evaluated in whole groups, for single and multiple, and for primary and recurrent tumours separately. RESULTS: At the time of the first cystoscopy (10-15 weeks after TUR) tumour recurrence was detected in 23 of 62 patients (37%) in group A, but only in five of 60 patients (8%) in group B. The recurrence-free survival rates in group A were 39% and 28% after 12 and 24 months, compared to 66% and 40% respectively in group B (P = 0.008, log-rank test). In separate analyses, the recurrence-free survival rates were significantly higher using FC in multiple (P = 0.001) and in recurrent (P = 0.02) tumours. In solitary and primary tumours the median time to recurrence was also longer in group B, but the difference was not statistically significant. CONCLUSION: 5-aminolaevulinic acid-induced FC during TUR reduces the recurrence rate in stage Ta/T1 bladder TCC. The most significant benefit is in patients with multiple and recurrent tumours.
