Background: As perception have been recently highlighted as critical determinants of clinical trials (CTs) in cancer patients, we evaluated current perceptional status of CTs in cancer patients, focusing on differences between common and rare cancers. Materials & Methods: From November 2015 to May 2017, we prospectively surveyed patients who have received anti-cancer treatment at Asan Medical Center using the PARTAKE questionnaires. Results: Among 333 respondents, 70.9% and 29.1% had common and rare cancers, respectively. While 87.7% and 75.3% of patients answered that they heard of and knew about CTs, willingness to participate in CTs was expressed only in approximately 56% of patients although willingness was significantly correlated with awareness and perception. Surprisingly, patients with rare cancers showed significantly lower levels of awareness and perception (64.2% vs 79.9%, p=0.003 and 77.3% vs 91.9%, p<0.001), and consequently less willingness (47.4% vs 58.9%, p=0.06) compared to patients with common cancers. In addition, cancer patients still harbored fear with concerns about safety and reward, and substantial ignorance and mistrust about voluntariness of CTs, which was more predominant in patients with rare cancers...Continue Reading
