For this study, the authors utilized rapid case ascertainment of the North Carolina Cancer Registry, identifying 1,456 patients enrolled from 2011-2013. NCCN risk group and treatments received (or active surveillance) were determined using medical records and registry data. Using a phone survey, patients were asked about their perceived cancer aggressiveness, most important decision-making factor (i.e., cure, quality of life, family burden, cost, daily activity), and desire to be involved in the decision process. Among the 585 low-risk patients, 38% pursued active surveillance. On multivariable analysis, patient desire to pursue aggressive treatment (very aggressive: OR 23.33, p <0.001) and perceived cancer aggressiveness (OR 4.66, p<0.001) were significantly associated with aggressive treatment instead of active surveillance. Furthermore, patients indicating that the primary decision was themselves (rather than their physician) were more likely to receive aggressive treatment (OR 1.76, p=0.23). In the subgroup of 346 very low-risk patients, 48% received active surveillance, and patient desire for aggressive treatment (OR 22.53, p<0.001) and perceived aggressiveness (OR 4.94, p<0.001) remained significant factors.
The authors concluded that patient desire for aggressive treatment and misperception of cancer aggressiveness were dominant factors for low-risk patients receiving aggressive treatment instead of active surveillance. Certainly, ascertaining patient goals for treatment and more accurate information about low-risk PCa may improve physician counseling/patient education and reduce inappropriate underutilization of active surveillance.
