PROBLEM: Question: Does extended pattern prostate biopsy minimize the volume-grade bias in prostate cancer detection?
Answer: Although more high grade cancers are detected with extended pattern biopsy, there is no differential upgrading with respect to prostate volume. Based on these observations extended prostate sampling in trials of agents that decrease prostate volume would have minimal impact on volume-grade associations.

SOLUTION: no
