Abstract
 

PURPOSE:

Using patient-reported outcomes measures, we identified the most informative set of factors associated with quality of life (QOL) in a large sample of men treated for localized prostate cancer.

MATERIALS AND METHODS:

We examined the relationships between QOL (FACIT) and hypothesized variables using a sample of men diagnosed with localized prostate cancer who represented different time points since treatment (<12 months: n=70; 1-3 years n=344; 3-5 years n=291; >5 years n=97). Correlative measures included sub-scales from the Memorial Anxiety Scale for Prostate Cancer (MAX-PC); short forms from the Patient Reported Outcomes Measurement Information System (PROMIS) and Surgical Outcomes Measurement System (SOMS); Treatment Decision-Making Satisfaction Scale (TDM-SATS); and sub-scales of the Big Five Inventory of personality (BFI).

RESULTS:

QOL was significantly associated with hypothesized variables across different time cohorts. In regression models, several factors accounted for a majority of the variability in QOL scores depending on time since treatment (47%, 22%, 29%, and 27%, respectively). Upon examining the unique contribution of these variables, treatment decision making satisfaction was the only one to have a significant (p<.01) and unique contribution to QOL across all time cohorts (standardized coefficients = .33, .27, .31, .49, respectively). In the 1-3 year since treatment cohort, erectile function and neurotic personality style also had unique associations with QOL (standardized coefficients = .25, -.20, respectively).

CONCLUSIONS:

When considering a man’s short and longer term QOL following treatment for localized prostate cancer, our findings highlight the importance of treatment decision making satisfaction, erectile function, and personality.
