Background
Active surveillance (AS) is under-utilized for low-risk prostate cancer. This study examines decision-making factors associated with AS vs aggressive treatment in a population-based cohort of low-risk patients.
Methods
Newly-diagnosed patients were enrolled through the North Carolina Central Cancer Registry from 2011–2013 (n = 599), and surveyed regarding 5 factors which may impact treatment decision-making: perceived cancer aggressiveness, aggressiveness of treatment intent, most important goal (eg, cure, quality of life), primary information source, and primary decision-maker. We examined the association between treatment decision-making factors with patient choice for AS vs aggressive treatment using multivariale logistic regression analysis.
Results
This is a sociodemographically diverse cohort reflective of the population-based design, with 37.6% overall (47.6% among very low-risk patients) choosing AS. Aggressive treatment intent (odds ratio [OR] = 7.09, 95% confidence interval [CI] = 4.57–11.01), perceived cancer aggressiveness (OR = 4.93, 95% CI = 2.71–8.97), most important goal (cure vs other, OR = 1.72, 95% CI = 1.12–2.63) and primary information source (personal/family vs physician, OR = 1.76, 95% CI = 1.10–2.82) were associated with aggressive treatment. Overall, 88.4% of patients (92.2% among very low-risk) who indicated an intent to treat the cancer “not very aggressively” chose AS.
Conclusions
These data from the patient’s perspective shed new light on potentially modifiable factors that can help further increase AS uptake among low-risk patients. Helping more low-risk patients feel comfortable with a “not very aggressive” treatment approach may be especially important, which can be facilitated throughpatient education interventions to improveunderstanding of the cancer diagnosis and AS having a curative intent.
