Neoadjuvant chemotherapy and bladder-sparing surgery for invasive bladder cancer: ten-year outcome

PURPOSE: To evaluate the 10-year outcome of patients with invasive (T2-3N0M0, staged according to the tumor, node, metastasis system) bladder cancer who responded completely to a combination of methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) chemotherapy followed by bladder-sparing surgery. PATIENTS AND METHODS: Of 111 surgical candidates who received neoadjuvant MVAC, 60 (54%) achieved a complete clinical response (T0) on transurethral resection (TUR) of the primary tumor site. Of these, 28 requested follow-up with TUR alone, 15 had a partial cystectomy, and 17 elected a radical cystectomy. The patients were followed up for a median of 10 years (range, 8 to 13 years). RESULTS: Of 43 patients who had bladder-sparing surgery, 32 (74%) are alive, which includes 25 (58%) with an intact functioning bladder. Twenty-four patients (56%) developed bladder tumor recurrences from 5 to 96 months, which were invasive in 13 (30%) and superficial in 11 (26%). Thirteen patients required a salvage cystectomy, of whom 6 died, which includes 4 (9%) from a new invasive neoplasm. Of the 17 patients who had radical cystectomy, 11 (65%) are alive. CONCLUSION: The majority of patients with invasive bladder tumors who achieve T0 status after neoadjuvant MVAC chemotherapy preserve their bladders for up to 10 years with bladder-sparing surgery. The bladder remains at risk for new invasive tumors. Cystectomy salvages the majority, but not all, of relapsing patients.     

The fate of patients with locally advanced bladder cancer treated conservatively with neoadjuvant chemotherapy, extensive transurethral resection and radiotherapy: 10-year experience

PURPOSE: We assess the results of bladder preservation for infiltrating bladder cancer. The potential for neoadjuvant chemotherapy followed by extensive transurethral resection and radiotherapy was evaluated in 40 patients with T2-T4a G2-G3 bladder carcinoma. MATERIALS AND METHODS: From 1983 to 1995, 40 patients with bladder cancer underwent bladder sparing treatment, consisting of neoadjuvant chemotherapy, extensive transurethral resection and radiotherapy. Most patients had T3G3 cancer. A deep transurethral resection biopsy was performed before and after chemotherapy, and an extensive transurethral resection was repeated at the end of radiotherapy. Of the patients 30 received cisplatin and methotrexate and 10 also received vinblastine. Total dose of radiotherapy was 60 to 65 Gy. Recurrent superficial tumors were treated transurethrally. Radical cystectomy was considered for persistent or recurrent invasive disease. RESULTS: Complete response occurred in 19 patients (47.5%) after chemotherapy, and in 8 patients after transurethral resection and radiotherapy (67.5%). Within 10 years 8 responding patients (30%) had local recurrences and 3 underwent cystectomy. Of the patients 14 (35%) are alive, including 13 with no evidence of disease (mean survival 65 months), 5 died of unrelated disease and 21 (52.5%) died of distant metastases (mean survival 28 months). Of the 21 patients 14 had residual tumor after radiotherapy, 3 presented with distant metastases after vesical infiltrating recurrence and 4 had distant metastases in the absence of locoregional recurrence. In 22 patients (55%) the bladder was salvaged. Patients with complete response to chemotherapy had a low risk for recurrent infiltrating tumors and metastases. CONCLUSIONS: Complete tumor control was maintained at 5 years in more than 50% of the patients treated conservatively. Bladder salvage is feasible in select patients.     

A phase I/II trial of transurethral surgery combined with concurrent cisplatin, 5-fluorouracil and twice daily radiation followed by selective bladder preservation in operable patients with muscle invading bladder cancer

PURPOSE: We describe a protocol designed to evaluate the use of twice daily radiation used together with cisplatin and 5 fluorouracil (5-FU) in the treatment of operable transitional cell carcinoma of the bladder with potential bladder preservation. MATERIALS AND METHODS: A total of 18 consecutive patients with T2-T4a bladder tumors underwent as complete a transurethral resection as possible, which was visibly complete in 14 cases. They then received twice daily radiation and infusion cisplatin and 5-FU during an induction phase. No therapy was given for 3 weeks, following which patients were reevaluated cystoscopically. Cases of clinical complete response by biopsy and cytology were consolidated with further chemotherapy/radiation using the same chemotherapeutic agents and radiation schedule. Patients who had incomplete responses were advised to undergo an immediate radical cystectomy. Of the 18 patients 15 subsequently received 3 cycles of adjuvant chemotherapy, consisting of methotrexate, cisplatin and vinblastine. Median followup for the entire group is 32 months. RESULTS: Of the 18 patients 14 had no detectable tumor after induction therapy. Of the 4 patients with persistent tumor 2 underwent radical cystectomy and 2 refused cystectomy, 1 of whom was treated with partial cystectomy and the other with consolidation chemotherapy/radiation. The actuarial overall survival at 3 years was 83%. The chance of a patient being alive at 3 years with a native bladder was 78%. No patient required cystectomy for hematuria or bladder shrinkage. Three patients in whom superficial tumors developed were treated successfully with bacillus Calmette-Guerin. Small bowel obstruction in 1 case was corrected surgically. CONCLUSIONS: This pilot study demonstrates a high rate of response to this combined chemotherapy/radiation regimen in conjunction with a visibly complete transurethral resection. Reevaluation after a short induction phase allows for the early selection of patients with persistent disease for radical cystectomy.     

Organ preservation with radiochemotherapy in locally advanced bladder cancer

Bladder cancer is frequent in Western countries and predominantly affects males (ratio: 3:1). In 15-25% of cases there is muscular wall invasion. Treatment of > T1 tumors is radical cystectomy with or without preoperative radiotherapy. In T2 there is 60% survival at 5 years, 40% in T3. Exclusive radiotherapy used to prevent radical cystectomy has lower survival rates in T2 (30-40% at 5 years) as well as in T3 (20% at 5 years). Recently, concomitant radiotherapy and chemotherapy has been introduced again to prevent demolitive surgery. Results are similar or slightly superior than those of surgery alone. In our experience with radiotherapy 180 cGy daily for a total dose of 64 Gy in combination with fluorouracil in locally advanced tumors 40% bladder preservation was achieved.     

Long-term followup of all patients with muscle invasive (stages T2, T3 and T4) bladder carcinoma in a geographical region

PURPOSE: We studied the relationship between long-term survival and treatment of stages T2, T3 and T4 bladder carcinoma in an unselected patient population. MATERIALS AND METHODS: A total of 680 patients with the initial diagnosis of bladder carcinoma in 1987 to 1988 in Western Sweden was prospectively registered and followed until 1994. Of these patients 107 had stage T2 to T3 and 41 had stage T4 disease. RESULTS: Of the patients with stage T2 to T3 disease 30 (mean age 66) underwent radical cystectomy, 33 (mean age 75) full dose radiotherapy and 44 (mean age 81) nonradical therapy (mainly transurethral resection of the bladder). The 5-year crude survival rates were 33, 15 and 14%, respectively. Of the patients with stage T4 disease 6 (mean age 61) underwent radical cystectomy, 9 (mean age 73) full dose radiotherapy and 26 (mean age 81) nonradical therapy (mainly transurethral resection of the bladder). All except 1 patient died of disease within 4 years. CONCLUSIONS: More than 60% of the patients in the cohort were considered unsuitable for radical cystectomy and their survival was poor, whether treated with full dose radiotherapy or transurethral resection of the bladder alone.     

Role of adjuvant chemotherapy in the treatment of invasive carcinoma of the urinary bladder

PURPOSE: The standard treatment for patients with muscle-invasive carcinoma of the urinary bladder is radical cystectomy. While radical cystectomy cures many patients with this tumor, almost 50% of them will develop metastatic disease. Adjuvant chemotherapy has been proposed for these patients in an attempt to reduce the probability of relapse and to improve survival. To assess whether adjuvant chemotherapy does benefit patients with muscle-invasive bladder cancer, we reviewed all phase II and III studies published in the English literature over the last 20 years. METHODS: A review of all published reports was facilitated by the use of Medline computer search and by manual search of the Index Medicus. RESULTS: Several comparative, nonrandomized studies have indicated that adjuvant chemotherapy may prolong disease-free survival. Four randomized studies have been conducted and all had a suboptimal patient accrual. Three studies used a cisplatin-containing combination chemotherapy and included primarily patients with non-organ-confined transitional-cell carcinoma (TCC) of the bladder. All three studies indicated that adjuvant chemotherapy improved disease-free survival and two of them also showed improvement in event-free survival and overall survival, respectively. CONCLUSION: Published series have been unable to establish an undisputed benefit of adjuvant chemotherapy over radical cystectomy alone for muscle-invasive bladder cancer. The interpretation of the available data is compromised by several methodologic and statistical problems. Thus, adjuvant chemotherapy cannot be considered as a standard treatment for all patients with muscle-invasive carcinoma of the bladder. Well-designed prospective randomized studies are needed to clarify the role of adjuvant chemotherapy in this disease. However, outside a protocol setting, there is some evidence that patients with extravesical disease or with lymph node involvement may benefit from adjuvant treatment with cisplatin-based combination chemotherapy. No data support such an approach for patients with muscle-invasive but organ-confined bladder cancer.     

Phase III trial of neoadjuvant chemotherapy in patients with invasive bladder cancer treated with selective bladder preservation by combined radiation therapy and chemotherapy: initial results of Radiation Therapy Oncology Group 89-03

PURPOSE: To assess the efficacy of neoadjuvant methotrexate, cisplatin, and vinblastine (MCV) chemotherapy in patients with muscle-invading bladder cancer treated with selective bladder preservation. PATIENTS AND METHODS: One hundred twenty-three eligible patients with tumor, node, metastasis system clinical stage T2 to T4aNXMO bladder cancer were randomized to receive (arm 1, n=61 ) two cycles of MCV before 39.6-Gy pelvic irradiation with concurrent cisplatin 100 mg/m2 for two courses 3 weeks apart. Patients assigned to arm 2 (n=62) did not receive MCV before concurrent cisplatin and radiation therapy. Tumor response was scored as a clinical complete response (CR) when the cystoscopic tumor-site biopsy and urine cytology results were negative. The CR patients were treated with an additional 25.2 Gy to a total of 64.8 Gy and one additional dose of cisplatin. Those with less than a CR underwent cystectomy. The median follow-up of all patients who survived is 60 months. RESULTS: Seventy-four percent of the patients completed the protocol with, at most, minor deviations; 67% on arm 1 and 81% on arm 2. The actuarial 5-year overall survival rate was 49%; 48% in arm 1 and 49% in arm 2. Thirty-five percent of the patients had evidence of distant metastases at 5 years; 33% in arm 1 and 39% in arm 2. The 5-year survival rate with a functioning bladder was 38%, 36% in arm 1 and 40% in arm 2. None of these differences are statistically significant. CONCLUSION: Two cycles of MCV neoadjuvant chemotherapy were not shown to increase the rate of CR over that achieved with our standard induction therapy or to increase freedom from metastatic disease. There was no impact on 5-year overall survival.     

Sequential transurethral surgery, multiple drug chemotherapy and radiation therapy for invasive bladder carcinoma: initial report

Forty-seven patients with muscle-invasive bladder cancer (T2-T4, Nx, M0) were treated by transurethral resection, followed by 3-4 cycles of combination chemotherapy (methotrexate 30 mg/m2 on days 1, 14; cis-platinum 100 mg/m2 on day 2; vinblastine 3 mg/m2 on days 1, 14; repeated every 21 days), and external beam irradiation (64-66 Gy to the bladder and 40 Gy to the pelvic lymphatics). Complete remission after trans urethral resection and chemotherapy was achieved in 24 out of 45 patients (53%). Cystectomy was performed in patients without complete response to transurethral resection and chemotherapy. The therapy was completed as planned in 45/47 patients. After transurethral resection, chemotherapy, and radiation therapy, biopsy proven complete response was achieved in 62% (28/45); Stage T2T3 in 67% (23/34), Stage T4 in 45% (5/11) of patients. Among 19 patients with positive biopsy findings after transurethral resection and chemotherapy, 14 underwent cystectomy. After follow-up of 4-55 months (median 23 months) 75% (34/45) are alive, 68% (31/45) have had their bladders preserved, and 53% (24/45) are free of the primary tumor. The actuarial survival of all 45 patients is 73%. Moderate nausea and vomiting during treatment were common; severe leukopenia and mucositis were observed in five patients. Late side effects such as miction disorders and diarrhea were predominantly mild. Although the observation period has been too short to allow a definitive evaluation of treatment results, we feel both from the point of bladder preservation and disease-free survival that the presented treatment approach is successful in a majority of T2T3 patients, whereas a large tumor size (T4) renders this treatment less effective.     

A miniature analytical instrument for nucleic acids based on micromachined silicon reaction chambers

BACKGROUND: The authors studied rapidly alternating chemotherapy and radiotherapy as the initial treatment for patients with muscle-invasive transitional cell carcinomas of the urinary bladder whose advanced age and lack of strength precluded cystectomy. METHODS: Twenty-one patients with T2 (28%) or T3 (72%) NXM0 carcinomas were treated by transurethral resection followed by chemoradiotherapy. Their median age was 73 years. The chemotherapy (consisting of methotrexate, vinblastine, doxorubicin, and cisplatin) was given during Weeks 1, 4 and 7. Radiotherapy (1.8-2 Gray [Gy] twice a day, to a total dose of 18-20 Gy per week) was given during Weeks 2, 5 and 8, for a final dose of 40 Gy to the pelvis plus 14-20 Gy boost to the affected bladder. RESULTS: There was 1 treatment-related death (5% of patients), but otherwise the acute toxicity was relatively mild. Cystoscopy 1 month after chemoradiotherapy did not reveal invasive cancer in any patient. Subsequent cystoscopies detected recurrent invasive cancer in 3 patients after 30, 44, and 82 months, respectively. The observed survival rate after 5 years was 37%, the cause specific survival rate was 63%, the metastasis free rate was 71%, and the local control rate was 80%. Eighty-four percent of patients had normal bladder function. CONCLUSIONS: Transurethral resection plus chemoradiotherapy was successful in preserving bladder function in the majority of the patients. The survival and progression free rates compared favorably with what has been reported recently after radical cystectomy and chemotherapy, and they add to the growing body of evidence that chemoradiotherapy might be a safe, effective alternative to cystectomy for many patients with muscle-invasive carcinoma of the urinary bladder.     

Organ-preserving therapy in invasive bladder carcinoma]

With the aim of organ preservation, transurethral resection with subsequent radiotherapy (until 1985) or combined radio- and chemotherapy (since 1986) was undertaken as part of a prospective trial in 175 consecutive patients (137 men, 38 women; mean age 65 [31-90] years) with invasive bladder carcinoma, tumour stage T1-4 N0-3 M0. All patients had a transurethral resection, followed 2-6 weeks later by definitive radiotherapy at a dose of 50.4 Gy to the bladder in 28 fractions. 85 patients simultaneously with the radiotherapy received chemotherapy with cisplatin (25 mg/m2 daily) or carboplatin (65-75 mg/m2 daily) in the first and fifth weeks of radiotherapy. The 5-year survival rate for the whole group (including inoperable cases) was 50%. The survival rate as related to the T category was 53% for T1 (n = 26), 68% for T2 (n = 34), 45% for T3 (n = 94) and 22% for T4 (n = 17). 139 patients (79%) were left with a normally functioning bladder. Cystectomy was performed in 36 patients because of remaining tumour or recurrence after radiotherapy. Combined radio- and chemotherapy improved the histological remission rate, compared with an earlier control group with radiotherapy only, but it did not affect the survival rate. These data indicate that in advanced bladder carcinoma organ-preserving treatment with transurethral resection and definitive radiotherapy or combined radio- and chemotherapy can be successful.     

Extravesical tumor implantation caused by perforation during transurethral resection of a bladder tumor: a case report

We report a case of invasive bladder cancer in which cancer dissemination occurred through a perforation of the vesical wall during transurethral resection of the tumor. A radical cystectomy was performed 1 month later and several clusters of viable cancer cells were histologically identified in a fibrous foreign body granuloma in the paravesicular adipose tissue of the lymphadenectomy specimen. The patient received adjuvant chemotherapy, but developed right inguinal lymph node metastasis 21 months after cystectomy.     

Survival in stage T2-T3A bladder cancer treated with radical cystectomy

OBJECTIVE: The optimal treatment for patients with localized muscle-infiltrating urothelial carcinoma (Jewett stage B or T2-T3a of the TNM classification, UICC 1992) continues to be a controversy. The present study analyzed the survival rate in patients with stage T2-T3a bladder cancer who had been treated by radical cystectomy. METHODS: The records of 50 patients with T2-T3a NO tumor, submitted to pelvic lymphadenectomy and radical cystoprostatectomy, were reviewed to determine the prognosis in this group of patients. Seventeen patients (34%) received three courses of systemic chemotherapy (CMV) prior to cystectomy. RESULTS: The overall 5-year survival rate was 73%; 76% for those with T2 (n = 30) and 67% for those with T3a (n = 20) (log-rank, p = 0.27). No statistically significant differences were observed for age (less than or over 65 years), tumor growth pattern (papillary or flat), tumor size (less or greater than 5 cms) or treatment (with or without induction CMV). However, patients with G1-2 tumor had a better survival rate (94% at 5 years) than those with G3 tumor (51%), a difference with statistical significance (log-rank, p = 0.047). The Cox regression analysis showed no independent variable of prognostic significance. CONCLUSION: Muscle-infiltrating urothelial carcinoma is highly curable by radical surgery. Some authors believe it is unnecessary to distinguish T2-T3a lesions; therefore a critical review of the TNM classification appears to be warranted. We are unable to distinguish patients with a better prognosis that might benefit from less aggressive therapeutic options. Similarly, the therapeutic benefits of induction chemotherapy prior to cystectomy in patients with stage T2-T3a tumor could not be demonstrated.     

Hyperfractionated irradiation with or without concurrent chemotherapy for locally advanced head and neck cancer

BACKGROUND: Radiotherapy is often the primary treatment for advanced head and neck cancer, but the rates of locoregional recurrence are high and survival is poor. We investigated whether hyperfractionated irradiation plus concurrent chemotherapy (combined treatment) is superior to hyperfractionated irradiation alone. METHODS: Patients with advanced head and neck cancer who were treated only with hyperfractionated irradiation received 125 cGy twice daily, for a total of 7500 cGy. Patients in the combined-treatment group received 125 cGy twice daily, for a total of 7000 cGy, and five days of treatment with 12 mg of cisplatin per square meter of body-surface area per day and 600 mg of fluorouracil per square meter per day during weeks 1 and 6 of irradiation. Two cycles of cisplatin and fluorouracil were given to most patients after the completion of radiotherapy. RESULTS: Of 122 patients who underwent randomization, 116 were included in the analysis. Most patients in both treatment groups had unresectable disease. The median follow-up was 41 months (range, 19 to 86). At three years the rate of overall survival was 55 percent in the combined-therapy group and 34 percent in the hyperfractionation group (P=0.07). The relapse-free survival rate was higher in the combined-treatment group (61 percent vs. 41 percent, P=0.08). The rate of locoregional control of disease at three years was 70 percent in the combined-treatment group and 44 percent in the hyperfractionation group (P=0.01). Confluent mucositis developed in 77 percent and 75 percent of the two groups, respectively. Severe complications occurred in three patients in the hyperfractionation group and five patients in the combined-treatment group. CONCLUSIONS: Combined treatment for advanced head and neck cancer is more efficacious and not more toxic than hyperfractionated irradiation alone.     

Neoadjuvant intra-arterial chemotherapy based on chemosensitivity tests for locally invasive bladder cancer

We investigated the clinical usefulness of individualization of chemotherapeutic regimen in neoadjuvant intra-arterial chemotherapy for locally invasive bladder cancer. Anticancer drugs were selected according to the results of an in vitro chemosensitivity test (collagen matrix assay or succinic dehydrogenase inhibition test). Nine patients with locally invasive bladder cancer received 1 to 4 courses of neoadjuvant intra-arterial chemotherapy, followed by radical cystectomy. Histopathological responses in the cystectomized specimens were grade 3 in 3 cases, grade 2 in 2, grade 1b in 2 and no response in 2. Pathologically, a complete response and downstaging were observed in 3 and 4 cases, respectively. Seven of the 9 patients were alive no evidence of disease with a mean follow-up period of 38.9 months, whereas 2 patients died of metastasis within 2 years. Six of the 7 patients who showed a complete response or down staging have been free of recurrence. These findings suggest that our chemotherapeutic strategy may improve the prognosis for locally invasive bladder cancer.     

The current role of radiotherapy in the treatment of invasive bladder cancer

Invasive bladder cancer remains a therapeutic challenge. Approximately 50% of patients treated with radical cystectomy die of metastatic disease. External beam radiation therapy when given alone has results inferior to that of surgery, and although it has shown some benefit when given in the preoperative setting, this was not verified by randomized trials. Altered fractionation radiation schemes and combined modality using a cisplatin-based combination chemotherapy with radiation have resulted in up to 60% bladder preservation.     

A case of asynchronous renal cell carcinoma and urothelial cancer of the urinary bladder and left ureter

A 49-year-old male with left renal cell carcinoma and urothelial cancer (bladder and residual left ureter), which asynchronously occurred, was reported. He had received radical nephrectomy due to renal cell carcinoma 12 years earlier. He was followed up by his local physician for 7 years postoperatively, during which time no metastatic lesion was detected. However, he presented with macroscopic hematuria on January 7, 1992, and a diagnosis of urinary bladder cancer was made at our hospital. Computerized tomography demonstrated a non-papillary, broad-based tumor on the left wall of the urinary bladder, which histologically was transitional cell carcinoma (grade 3). Radical cystectomy, ureterectomy of the left residual ureter and ileal conduit were performed. Histological examinations showed that the urinary bladder tumor was transitional cell carcinoma, grade 3, pT-3b, and CIS (transitional cell carcinoma, grade 3) was found in the residual left ureter. Chemotherapy containing cis-platinum was performed as an adjuvant therapy, but multiple lung metastatic lesions appeared 2 months postoperatively, the histology of which was transitional cell carcinoma, suggesting metastasis from the urothelial cancer. Chemotherapy was ineffective, and he died of the disease 9 months after the operation. If this patient had been under long-term follow-up, the urothelial cancer may have been resected completely by transurethral resection. Our report indicated the importance of examination of the urinary tract in patients with such cancers, as well as the necessity of long-term follow-up.     

Five-year followup of a prospective trial of radical cystectomy and neoadjuvant chemotherapy: Nordic Cystectomy Trial I. The Nordic Cooperative Bladder Cancer Study Group

PURPOSE: Chemotherapy is widely used in patients with locally advanced bladder cancer but until now there has been no conclusive evidence that this therapy improves survival. The Nordic Cooperative Bladder Cancer Study Group conducted a randomized phase III study to assess the possible benefit of neoadjuvant chemotherapy in patients with bladder cancer undergoing radical cystectomy after short-term radiotherapy. MATERIALS AND METHODS: Our trial included 325 patients with locally advanced stage T1 grade 3 or stages T2 to T4aNXM0 bladder cancer allocated randomly into a chemotherapy or no chemotherapy group (control). The chemotherapy schedule consisted of 2 cycles of 70 mg./m.2 cisplatin and 30 mg./m.2 doxorubicin with a 3-week interval between the cycles. RESULTS: After 5 years the overall survival rate was 59% in the chemotherapy group and 51% in the control group (p = 0.1). The corresponding cancer specific survival rate was 64 and 54%, respectively. In regard to treatment, no difference was observed for stages T1 and T2 disease, while there was a 15% difference in overall survival for patients with stages T3 to T4a disease (p = 0.03). In a multivariate analysis only chemotherapy and T category emerged as independent prognostic factors. The relative death risk for patients who received chemotherapy was 0.69 (95% confidence interval 0.49 to 0.98) compared to the control group after adjustment for the other tested factors. CONCLUSIONS: Neoadjuvant chemotherapy seems to improve long-term survival after cystectomy in patients with stages T3 to T4a bladder carcinoma, while no survival benefit was found for stages T1 to T2 disease.     

Combined radiation therapy and cisplatin for locally advanced carcinoma of the urinary bladder

BACKGROUND: This study evaluates feasibility and results of combined treatment of cisplatin and radiation therapy for patients with inoperable invasive bladder carcinoma. METHODS: From January 1988 to October 1991, 69 patients received radiation therapy and concomitant cisplatin. Median age was 71 years. Most tumors were locally advanced and high grade. A macroscopically complete transurethral resection was performed initially in 18 patients. Dose of pelvic radiation ranged from 40 Gy to 45 Gy, and total dose to the bladder ranged from 55 Gy to 60 Gy. Concomitant continuous cisplatin infusion at a dose of 20-25 mg/m2/day for 5 days was delivered during the 2nd and 5th weeks of radiation. RESULTS: As of April 1993, the median follow-up time was 36.4 months (range, 18-70 months). Ninety-one percent of the patients completed radiation therapy as planned, and 78.3% completed two courses of chemotherapy. Despite one treatment-related death due to renal failure, toxicity was generally mild and acceptable. Sixty-three patients were evaluable for response. Forty-eight patients (76.2%) achieved a complete response. Actuarial overall 3-year survival rate was 37.1% for all patients. Among the patients who experienced complete response, the 3-year actuarial local control and disease-free survival rates were 65.4% and 56.3%, respectively. Twenty-six patients (37.7%) are alive and disease-free with bladder preservation. One patient is alive and disease-free after salvage cystectomy. CONCLUSIONS: Concomitant cisplatin and radiation therapy offers high probability of complete response and local control in patients with invasive bladder cancer unsuitable for surgery. These results provide a basis for randomized studies comparing this approach with conventional therapy for patients with operable carcinoma.     

Late invasive recurrence despite long-term surveillance for superficial bladder cancer

Superficial transitional cell carcinoma of the bladder is associated with a 15 to 70% recurrence rate within 2 years. Most recurrences are superficial. A recurrence after 2 disease-free years is unusual. A review of the tumor registry revealed 124 patients followed for superficial disease at the Veterans Administration Center in Baltimore. Of the patients 20 were identified with either stage Ta (7) or stage T1 (13) papillary transitional cell carcinoma who had completed at least 5 years of surveillance without tumor recurrence. Invasive transitional cell carcinoma of the bladder requiring cystectomy developed in 7 of these 20 patients after remaining tumor-free for 5 years (stage Ta in 4 and stage T1 in 3). All 7 patients had organ-confined disease and were alive with no evidence of disease at 18 months to 5 years after cystectomy. These results demonstrate that superficial, low grade transitional cell carcinoma of the bladder can become muscle invasive despite careful surveillance and a long dormant period. In our series yearly cystoscopy and urine cytology identified tumor recurrence before metastases developed, suggesting that long-term surveillance is required in patients with superficial bladder cancer.     

Factitious orbital emphysema: an unusual presentation of Munchausen''s syndrome

The role of radical cystectomy as the standard treatment of localised infiltrating bladder malignancy is challenged by the development radiotherapy and chemotherapy combinations. The published studies are difficult to compare because of large differences in the patients selection criteria and in the assessment of local involvement (only clinical in combined treatment, based on pathology and therefore unquestionable in surgical series). The advantages of radical surgery are its precedence and a well-established technique, simplified follow-up procedures and seemingly higher survival rates acquired after 3 years. Conversely, the combination of radiotherapy and chemotherapy allows bladder preservation in about 40% of the patients (at 5 years), but only in 23% without bladder relapses. A complete initial endoscopic resection is the best and only prognostic factor of these results which nevertheless needs a very carefully and endless follows. The comparison of the quality of life achieved by both treatment modalities remains insufficiently documented.
