Radical cystectomy for urothelial carcinoma of the bladder without neoadjuvant or adjuvant therapy: long-term results in 1100 patients.

BACKGROUND: The optimal treatment strategy for muscle-invasive bladder cancer (BCa) remains controversial. OBJECTIVE: Better define the long-term outcomes of radical cystectomy (RC) alone for BCa and determine the impact of pathologic downstaging after transurethral resection in a large and homogeneous single-center series. DESIGN, SETTING, AND PARTICIPANTS: A cohort of 1100 patients undergoing RC with pelvic lymph node dissection (PLND) without neoadjuvant therapy for urothelial carcinoma of the bladder between January 1, 1986, and December 2009 was evaluated. Patients with other than metastases to the pelvic lymph nodes were excluded. Median age was 65 yr. Clinical course, pathologic characteristics, and long-term outcomes were evaluated. Follow-up was obtained until December 2009 with a median of 38 mo and a completeness of 96.5%. INTERVENTION: RC with PLND; urinary diversion with ileal neobladder whenever possible. MEASUREMENTS: Primary end points were disease-specific survival (DSS), recurrence-free survival (RFS), and overall survival (OS) according to the tumor stage of the RC specimen versus the maximum tumor stage. The log-rank test was used to compare subgroups. RESULTS AND LIMITATIONS: The 30-d (90-d) mortality rate was 3.2% (5.2%). The 10-yr OS, DSS, and RFS rates were 44.3%, 66.8%, and 65.5%, respectively. Based on the tumor stage of the RC specimen, the 10-yr DSS rate was pT0/a/is/1 pN0: 90.5%, pT2a/b pN0: 66.8%, pT3a/b pN0: 59.7%, pT4a/b pN0: 36.6%, and pTall pN+: 16.7%. Downstaging by transurethral resection of the prostate was observed in 382 patients. Patients with maximum tumor stage pT2a/b pN0 had distinctly better 10-yr DSS rates than those with pT2a/b pN0 in the RC specimen: pT2a pN0: 92.2% versus 73.8%; pT2b: 75.0% versus 62.0%. A total of 49% female and 80% male patients received an ileal neobladder. CONCLUSIONS: This contemporary and homogeneous single-center series found acceptable OS, DFS, and RFS for patients undergoing RC. Pathologic downstaging had a significant impact on survival.

25 years of experience with 1,000 neobladders: long-term complications.

PURPOSE: We analyzed the long-term complications (greater than 90 days postoperatively) in a large, single center series of patients who underwent cystectomy and substitution with an ileal neobladder. MATERIALS AND METHODS: A total of 1,540 radical cystectomies were performed at our center between January 1986 and September 2008. Of the patients 1,013 received an ileal neobladder. Only the 923 patients with followup longer than 90 days (median 72 months, range 3 to 267) were included in analysis. All long-term complications were identified. The complication rate was calculated using the Kaplan-Meier method. RESULTS: The overall survival rate was 65.5%, 49.8% and 28.3% at 5, 10 and 20 years, respectively. The overall long-term complication rate was 40.8% with 3 neobladder related deaths. Hydronephrosis, incisional hernia, ileus or small bowel obstruction and feverish urinary tract infection were observed in 16.9%, 6.4%, 3.6% and 5.7% of patients, respectively, 20 years postoperatively. Subneovesical obstruction in 3.1% of cases was due to local tumor recurrence in 1.1%, neovesicourethral anastomotic stricture in 1.2% and urethral stricture in 0.9%. Chronic diarrhea was noted in 9 patients. Vitamin B12 was substituted in 2 patients. Episodes of severe metabolic acidosis occurred in 11 patients and 307 of 923 required long-term bicarbonate substitution. Rare complications included cutaneous neobladder fistulas in 2 cases, and intestinal neobladder fistulas, iatrogenic neobladder perforation, spontaneous perforation and necrotizing pyocystis in 1 each. CONCLUSIONS: Even in experienced hands the long-term complication rate of radical cystectomy and neobladder formation are not negligible. Most complications are diversion related. The challenge of optimum care for these elderly patients with comorbidities is best mastered at high volume hospitals by high volume surgeons.

Lessons learned from 1,000 neobladders: the 90-day complication rate.

PURPOSE: We report the 90-day morbidity of the ileal neobladder in a large, contemporary, homogenous series of patients who underwent radical cystectomy at a tertiary academic referral center using a standard approach. MATERIALS AND METHODS: Between January 1986 and September 2008 we performed 1,540 radical cystectomies. A total of 281 patients had an absolute contraindication for orthotopic reconstruction. The remaining 1,259 patients were candidates for a neobladder. Of these patients 1,013 (66%) finally received a neobladder and form the basis of this report. All patients had a thorough followup until December 2008 or until death. All complications within 90 days of surgery were defined, categorized and classified by an established 5 grade and 11 domain modification of the original Clavien system. RESULTS: Of 1,013 patients 587 (58%) experienced at least 1 complication within 90 days of surgery. Infectious complications were most common (24%) followed by genitourinary (17%), gastrointestinal (15%) and wound related complications (9%). The 90-day mortality rate was 2.3%. Of the patients 36% had minor (grade 1 to 2) and 22% had major (grade 3 to 5) complications. On univariate analysis the incidence and severity of the 90-day complications rate correlate highly significantly with age, tumor stage, American Society of Anesthesiologists score and preoperative comorbidity. CONCLUSIONS: Radical cystectomy and ileal neobladder formation represent a major surgery with potential relevant early complications even in the most experienced hands. The rate of severe and lethal complications is acceptably low.

Cystectomy for transitional cell carcinoma of the bladder: results of a surgery only series in the neobladder era.

PURPOSE: We studied the effect of radical cystectomy for transitional cell carcinoma of the bladder on survival and failure patterns when the 2 surgical standards cystectomy and neobladder were combined, when possible. MATERIALS AND METHODS: A consecutive series of patients undergoing radical cystectomy with pelvic lymph node dissection for transitional cell carcinoma of the bladder with curative intent was analyzed. Patients with neoadjuvant radiotherapy/chemotherapy were excluded. Pathological characteristics based on the 2002 TNM system, recurrence-free/overall survival and metastatic patterns were determined. RESULTS: A total of 788 patients with a mean age +/- SD of 65 +/- 10 years and a mean followup of 53.5 months who underwent surgery between 1986 and 2003 were analyzed. A neobladder was constructed in 75.4% of patients. Ten-year recurrence-free and overall survival rates were 59.1% and 44.9%, respectively. Positive lymph nodes were present in 143 patients (18%). The rate of recurrence-free survival at 5 years was 82.5% for pT2a pN0, 61.9% for pT2b and pT3a pN0, and 53.1% for pT3b pN0 disease. Local and distant failure rates were 4% and 9.5% for organ confined tumors, 15.9% and 19.2% for nonorgan confined tumors, and 20.4% and 45.1% in patients with positive lymph nodes, respectively. CONCLUSIONS: In patients with organ confined, lymph node negative transitional cell carcinoma excellent survival data can be achieved as long as the tumor is limited to the inner half of the detrusor. These data on a large group of patients support early aggressive surgical management for invasive bladder cancer. The results of this surgery only series may serve as a reference for other treatment modalities for bladder cancer.
