CEASAR (Comparative Effectiveness Analysis of Surgery and Radiation for Localized Prostate Cancer) is an ongoing multi-site research study conducting long-term follow-up on more than 3,600 men in the United States diagnosed with localized prostate cancer between the years 2010 and 2011.
CEASAR is coordinated by Vanderbilt University Medical Center (Nashville, TN), and includes participants enrolled through the following six sites across the United States:

At the time of enrollment, eligible participants must have met the following criteria:
**Please note that CEASAR is currently in the long-term follow-up stage and is no longer enrolling new participants.
As the ongoing goal for CEASAR is “to help learn more about what treatment works best, for which patients, and in whose hands,” surveys are administered to enrolled participants at established time points. These surveys include questions relating to the participant's quality of life and other experiences related to their prostate cancer.
To date, participants have recieved surveys at five time points: a baseline survey completed within 6 months of their prostate cancer diagnosis, and subsequent follow-up surveys administered at 6 months, 12 months (1 year), 36 months (3 years), and 60 months (5 years).
