What is 'progression' in prostate cancer?

Abstract

If progression can be defined at an early stage, a change in treatment may significantly improve the length and quality of apatient's survival. In this seminar, involving 35 participants, the assessment of progression in phase I1 and phase 111 studies was discussed, against the background of papers prepared by the invited participants, and an analysis of progression in a recent EORTC phase 111 study prepared by Dr. Sylvester.
