Efficient delivery of radical cystectomy after neoadjuvant chemotherapy for muscle‐invasive bladder cancer

BACKGROUND: Cystectomy delay >90 days after a diagnosis of muscle‐invasive bladder cancer (MIBC) adversely affects pathologic stage and survival outcomes in patients who undergo primary surgery. After neoadjuvant chemotherapy (NAC), the impact of the timing of cystectomy delivery on these outcomes is uncertain. Poor communication between urologic and medical oncologists can result in cystectomy delay after systemic treatment. The authors of this report hypothesized that a delay in cystectomy delivery after NAC is associated with adverse survival outcomes. METHODS: An eligible cohort of 153 patients with MIBC received NAC and underwent radical cystectomy between 1990 and 2007. At the authors' institution, the genitourinary team strives to schedule patients for surgery at the time of initial evaluation or after their first chemotherapy cycle. Clinicopathologic characteristics, including timing of cystectomy, chemotherapy delivery, vital status, and reasons for excessive surgical delay, were analyzed retrospectively using an institutional database. A Cox proportional regression model was used to test the association between the timing of cystectomy delivery and survival. RESULTS: The median follow‐up for all patients was 3.6 years. The median time to cystectomy was 16.6 weeks and 6.9 weeks from the first and last day of NAC, respectively. In multivariate analyses, the timing of cystectomy delivery from the termination of NAC did not significantly alter the risk of survival. The most common reason for cystectomy delivery beyond 10 weeks (28 patients; 18%) was procedural scheduling. CONCLUSIONS: Cystectomy delivery within 10 weeks after NAC did not compromise patient survival and, thus, provided a reasonable window for patient recovery and surgical intervention.

The authors analyzed the timing between the termination of neoadjuvant chemotherapy and cystectomy and assessed its impact on the survival of patients with muscle‐invasive bladder cancer. By using a multidisciplinary approach, the authors determined that the median time to cystectomy was 6.9 weeks. The results indicated that undergoing cystectomy within 10 weeks after the completion of neoadjuvant chemotherapy did not compromise cancer‐specific or overall survival.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/89461/1/26240_ftp.pd

Pattern of Failure in Bladder Cancer Patients Treated with Radical Cystectomy: Rationale for Adjuvant Radiotherapy

Thus far, the role of adjuvant radiotherapy (RT) after radical cystectomy (RC) in urinary bladder cancer patients has yet to be defined. The purpose of this study is to analyze patterns of failure, and suggest the rationale for RT. Between 1986 and 2005, a total of 259 patients treated with RC and pelvic lymph node dissection was enrolled. The age range was 27-82 yr (median, 62 yr). Node positivity increased according to tumor staging. Patients were divided into the following two groups based on pathologic analysis: organ-confined disease group (n=135) and extravesical/lymph node-positive disease group (n=80). Pelvic failures (PF) were observed in 8 (4.9%) in organ-confined disease group, and 21 (21.7%) in extravesical/lymph node-positive disease group. Five-year PF-free survival rates were 91.2% in organ-confined disease group and 68.0% in extravesical/lymph node-positive disease group. Five-year cancer-specific survival rates were 86.2% in organ-confined disease group and 53.9% in extravesical/lymph node-positive disease group. In conclusion, a relatively high PF rate was observed in extravesical lymph node-negative and lymph node-positive disease patients in this study. Adjuvant pelvic RT may be considered to reduce pelvic failures in extravesical lymph node-positive bladder cancer. Future prospective trials are required to test the clinical benefit of adjuvant RT
