Treatment choice should take into account both health status and tumor risk, as both appear to strongly influence the absolute benefit of treatment. Randomized clinical trial data have not provided a clear answer to this question, because neither trial of surgery nor watchful waiting was powered to detect differences in survival among subgroups of tumor risk and age and/or health status in combination. The PIVOT trial showed a trend toward survival benefit for surgery over watchful waiting for intermediate- and high-risk tumors, although some of these patients were younger than 65. 3 Wilt T.J.
