Welcome to the CEASAR prostate cancer study

CEASAR stands for Comparative Effectiveness Analysis of Surgery and Radiation. The ongoing goal of CEASAR is to help learn more about what prostate cancer treatments work best, for which patients, in whose hands.

There are currently about 3,600 men with a prostate cancer diagnosis participating in CEASAR. Three rounds of surveys have been completed, with the first carried out in the spring of 2010.  We are currently in the process of conducting our fourth survey wtih the same group of men in our study.  This survey, our Three Year Follow-up, will occur throughout 2014.

In addition to continuing to collect more data through additional surveys, we are also now working to analyze the data from earlier surveys and to present our findings through research papers and presentations.  Copies of published papers can be found here.
