Identification of surrogate outcomes

Using individual participant data, we will identify early measures of prostate cancer control (e.g. PSA, disease progression) that might predict later survival.  These early measures can be used to shorten new trials.  We will start with data from older completed trials so we can do this faster.  We will check again when we have collected data from newer trials.

We will use a similar approach to the ICECAP in non-metastatic disease effort.
