We compared the quality of life (QOL) between patients with metastatic hormone-sensitive prostate cancer who were treated with ADT+D and those who were treated with ADT alone. </p> </div><div class="section"> <a class="named-anchor" id="d5205831e201"> <!-- named anchor --> </a> <h5 class="section-title" id="d5205831e202">Methods</h5> <p id="d5205831e204">Men were randomly assigned to ADT+ D (six cycles) or to ADT alone. QOL was assessed by Functional Assessment of Cancer Therapy-Prostate (FACT-P), FACT-Taxane, Functional Assessment of Chronic Illness Therapy-Fatigue, and the Brief Pain Inventory at baseline and at 3, 6, 9, and 12 months. The Wilcoxon signed rank test was used to examine changes over time. Mixed-effect models compared the QOL between arms at each time point. </p> </div><div class="section"> <a class="named-anchor" id="d5205831e206"> <!-- named anchor --> </a> <h5 class="section-title" id="d5205831e207">Results</h5> <p id="d5205831e209">Seven hundred ninety men were randomly assigned (ADT+D [n = 397] and ADT[ n = 393]) and completed FACT-P (90% at baseline, 86% at 3 months, 83% at 6 months, 78% at 9 months, and 77% at 12 months). ADT+D patients reported a statistically significant decline in FACT-P at 3 months ( <i>P</i> &lt; .001) but FACT-P did not differ significantly between baseline and 12 months ( <i>P</i> = .38). ADT+D FACT-P scores were significantly lower at 3 months ( <i>P</i> = .02) but significantly higher at 12 months ( <i>P</i> = .04) when compared with ADT FACT-P scores. Differences did not exceed the minimal clinically important difference at any time point. ADT+D patients reported significantly lower Functional Assessment of Chronic Illness Therapy-Fatigue scores at 3 months than did ADT patients ( <i>P</i> &lt; .001). Over time, both arms reported significantly poorer FACT-Taxane scores ( <i>P</i> &lt; .001) when compared with baseline. Brief Pain Inventory scores were similar between arms. </p> </div><div class="section"> <a class="named-anchor" id="d5205831e230"> <!-- named anchor --> </a> <h5 class="section-title" id="d5205831e231">Conclusion</h5> <p id="d5205831e233">Although ADT+D was associated with statistically worse QOL at 3 months, QOL was better at 12 months for ADT+D patients than for ADT patients. Both arms reported a similar minimally changed QOL over time, suggesting that ADT+D is not associated with a greater long-term negative impact on QOL. </p> </div>
