design comments<br />

Auth<strong>or</strong>s’ conclusions:<br />

Patients <strong>with</strong><br />

asymptomatic progressive<br />

disease had a significantly<br />

higher response rate when<br />

treated <strong>with</strong> mitoxantrone<br />

plus <strong>prednisone</strong> than when<br />

treated <strong>with</strong> <strong>prednisone</strong><br />

alone, measured by a<br />

≥ 50% decrease in PSA.<br />

Time to <strong>treatment</strong> failure<br />

in <strong>the</strong> I group was also<br />

significantly longer but<br />

survival rates were not<br />

affected<br />

Outcome 1: Overall survival (N = 119)<br />

I: median = 23 months (range: 3–49)<br />

C: median = 19 months (range: 2–50)<br />

No significant difference<br />
