- W2590929093 abstract "135 Background: Active surveillance (AS) has emerged as a viable option for many men with early stage prostate cancer (PC). This approach of careful monitoring with prostate-specific antigen (PSA) level, digital rectal examination, and prostate biopsy may allow men to avoid or delay the potentially debilitating side effects of such aggressive treatments as surgery or radiation; however, AS may create uncertainty and anxiety for men with PC. We examined the associations between illness uncertainty and anxiety and general and PC-specific quality of life (QOL) of 191 men with favorable-risk PC participating in the AS program at MD Anderson Cancer Center. Methods: Men completed measures of uncertainty (Mishel Uncertainty in Illness Scale), anxiety (State-Trait Anxiety Inventory), and general (SF-12, Physical Health [PCS] and Mental Health Component Score [MCS]) and disease-specific (Expanded Prostate Index Composite [EPIC]) QOL questionnaires upon study entry and every 6 months. These results are through a 2.5 year follow-up. Results: Men were primarily (86%) white and an average age of 67.2 (SD=8.9). Average baseline PSA was 3.3 ng/mL (SD=1.6), 98% had a Gleason score of 6, and 85% had cT1c disease. Both general and PC-specific QOL were relatively unchanged across the 2.5 year study period, except for statistically significant declines in the EPIC Sexual score (p<0.05). Controlling for demographic (age, ethnicity) and clinical characteristics (study entry PSA, PSA density, testosterone, BMI, baseline number of biopsies, family history of cancer, whether patients were taking a 5-alpha-reductase inhibitor, and whether the tumor was reclassified during the study), illness uncertainty was a significant predictor of all EPIC summary scores, PCS, and MCS (all, p<0.05). Anxiety was also a significant predictor of all EPIC summary scores and MCS (all, p<0.05), but not PCS (p=0.08). Conclusions: Both increased anxiety and increased illness uncertainty were associated with poorer general and disease specific QOL. Interventions that focus on reducing uncertainty and anxiety may enhance the QOL of men on AS for PC." @default.
