title: Oncological outcomes after radical cystectomy for bladder cancer: open versus minimally invasive approaches.
abstract: OBJECTIVE
  The number of centers performing robotic assisted radical cystectomy has recently increased, spurring greater concerns about oncological outcomes. In this review we summarize the most comprehensive articles published on the oncological outcomes of laparoscopic assisted, robotic assisted and open radical cystectomy.
  
  
  METHODS
  A MEDLINE/PubMed literature search was conducted in March 2009 to review English language articles published from 1998 onward. Of 217 selected articles on the 3 techniques 19 studies were selected for this review.
  
  
  RESULTS
  The laparoscopic series reported recurrence-free survival rates in the range of 83% to 85% at 1 to 2 years and 60% to 77% at 2 to 3 years, while the robotic assisted studies reported recurrence-free survival rates of 86% to 91% at 1 to 2 years. Large open surgery studies showed 62% to 68% recurrence-free survival at 5 years and 50% to 60% at 10 years, with overall survival of 59% to 66% at 5 years and 37% to 43% at 10 years. Overall survival in the laparoscopic cohorts was 90% to 100% at 1 to 2 years and 50% to 87% at 2 to 3 years. Publications reporting robotic cases demonstrated a 90% to 96% overall survival in 1 to 2 years of followup.
  
  
  CONCLUSIONS
  Despite the surge of centers adopting minimally invasive approaches for radical cystectomy, the long-term effectiveness of these techniques has not yet been proven. This review of recent and landmark articles on open and minimally invasive procedures emphasizes the need for prospective controlled studies and long-term followup data to determine the proper use of laparoscopic and robotic assisted techniques in bladder cancer surgery.
