|Abstract:||OBJECTIVE: While androgen deprivation therapy (ADT) has been associated with decreased quality of life (QoL), controlled prospective studies are lacking. We aimed to assess QoL during ADT using two validated questionnaires and determine contributing factors. DESIGN: Prospective controlled study. PATIENTS: 63 men with non-metastatic prostate cancer newly commencing ADT (n=34) and age- and radiotherapy-matched prostate cancer controls (n=29). MEASUREMENTS: QoL was measured by Short-Form 12 version 2 survey (SF-12) and Aging Males' Symptoms (AMS) score at 0, 6 and 12 months. Generalised linear models determined the mean adjusted difference (MAD) [95% confidence interval] between groups during follow-up. RESULTS: Compared to controls over 12 months, men receiving ADT had decreased SF-12 physical component score (MAD -3.61 [-6.94, -0.29], p=0.013) reflecting worsening QoL but no change in the mental component (p=0.74). Total AMS score increased (MAD 9.35 [5.65, 13.07], p <0.001), reflecting worse QoL. Both SF-12 and AMS changes were greater than reported minimum clinically important differences. AMS sub-domains showed increased somatic (MAD 3.96 [1.94, 5.99], p<0.001) and sexual (MAD 3.80 [2.16, 5.44], p<0.001) components but not psychological (p=0.19). Decrements were related to an increase in hot flushes (p=0.016) but not haemoglobin decrease (p=0.46). CONCLUSIONS: Within 12 months, ADT is associated with clinically significant decreased QoL, particularly physical and sexual aspects, independent of the confounding effects of a cancer diagnosis or radiotherapy. As QoL is a crucial aspect of prostate cancer treatment, addressing hot flushes, sexual dysfunction and exercise may potentially improve outcomes for men undergoing ADT.|
