Abstract

Background: Sleep disturbances are prevalent among men with non-metastatic prostate cancer (NMPC) undergoing treatment, and correct sleep assessment is crucial for comprehensive care. Research-grade actigraphy devices are valuable tools for evaluating sleep duration and quality. This study investigated the effects of androgen deprivation therapy (ADT) and external beam radiation therapy (EBRT) on sleep activity (SA) patterns of men with NMPC.
Methods: This NIH IRB-approved study (NCT00852111) enrolled men with NMPC receiving EBRT+ADT. Sleep data from Actical® and sleep logs of 98 men with NMPC (63 received EBRT, 35 active surveillance (AS) controls) were collected at three phases: Time 1 (pre-EBRT), Time 2 (mid-EBRT), and Time 3 (post-EBRT). Sleep efficiency (SE), sleep duration (SD), total sleep time (TST), wake after sleep onset (WASO), midsleep duration (MSD), and reported sleep time (RST) were extracted using the Tudor-Locke algorithm. Data filtration was implemented to remove sleep periods outside of 3-12 hours.
Results: At Time 1, no differences in sleep variables between AS and EBRT patients. Significant effect of treatments on WASO (p=0.034) was observed, specifically by ADT use (p=0.031). Participants using ADT exhibited higher WASO across all phases compared to non-users. Treatment phase significantly affected RST (p=0.041) with significant reductions mid-EBRT (425.59±67.36 minutes) compared to post-EBRT (476.63±88.68 minutes, p=0.01).
Conclusion: ADT use contributes to increased sleep fragmentation during and following EBRT in men with NMPC. Treatment phase appears to be a key factor influencing variations in RST, suggesting the importance of phase-specific interventions to manage sleep disturbances in this population.
