Clinical Complete Response after Neoadjuvant Chemotherapy for Muscle-invasive Bladder Cancer: A Call for Standardized Assessments and Definitions

The ability to accurately determine a complete clinical response (cCR) to neoadjuvant chemotherapy (NAC) before cystectomy could have paradigm-shifting implications for the management of muscle-invasive bladder cancer. Level 1 evidence demonstrates that up to 40% of patients are downstaged to pT0 disease following NAC, presenting an intriguing opportunity to identify select patients who might be spared the morbidity of radical surgery. However, clinical investigations in this space are hindered by lack of a uniform approach to postchemotherapy restaging and a standardized definition of cCR. PATIENT SUMMARY: In this mini-review, we discuss the current limitations to restaging of muscle-invasive bladder cancer following neoadjuvant chemotherapy and their implications for personalized medicine and translational research. We conclude that there is an unmet need to optimize and standardize restaging evaluation and definitions of a complete clinical response

Robotic assisted radical cystectomy versus open radical cystectomy: a review of what we do and don't know

Radical cystectomy (RC) is the gold standard treatment for muscle-invasive and high-risk, noninvasive bladder cancer. Since 2003, robot-assisted radical cystectomy (RARC) has been gaining popularity. Metanalyses show that the primary advantage of RARC is less blood loss and the primary advantage of open radical cystectomy (ORC) is shorter operative times. There do not appear to be significant differences in complications, cancer-related outcomes or survival between the two approaches. Cost analyses comparing RARC and ORC are complicated by the often-ill-defined distinction between the cost to the hospital versus the cost to payors. However, it is likely that for both hospitals and payors, RARC is cost effective at high-volume centers. It is feasible that in the future, increased experience with RARC will lead to improved outcomes and justify the use of RARC over ORC
