A prospective comparison of cancer clinical trial availability and enrollment among adolescents/young adults treated at an adult cancer hospital or affiliated children's hospital.

ABSTRACT: BACKGROUND:Low cancer clinical trial (CCT) enrollment may contribute to survival disparities affecting adolescents and young adults (AYAs) (ages 15-39 years). The objective of this study was to evaluate whether differences in CCT availability related to treatment site could explain the low CCT enrollment. METHODS:This prospective, observational cohort study was conducted at an academic children's hospital and its affiliated but geographically separated adult cancer hospital within a National Cancer Institute-designated Comprehensive Cancer Center. For consecutive, newly diagnosed AYA patients, it was determined whether an appropriate CCT existed nationally, was available at the treatment site, and was used for enrollment. Proportions of AYAs in these categories were compared between sites using the chi-square test. RESULTS:One hundred fifty-two consecutive AYA patients were included from the children's hospital (n = 68; ages 15-20 years) and the adult cancer hospital (n = 84; ages 18-39 years). Although there was no difference in CCT existence for individual AYA patients by site (children's hospital [36 of 68 patients; 52.9%] vs adult cancer hospital [45 of 84 patients; 53.6%]; P = .938), CCT availability was significantly lower at the adult cancer hospital (14 of 84 patients [16.7%] vs 30 of 68 [44.1%] at the children's hospital; P < .001). The proportion of AYAs enrolled was low at both sites (8 of 68 patients [11.8%] vs 6 of 84 patients [7.1%], respectively; P = .327). Fewer existing CCTs were available at the adult cancer hospital (4 of 27 patients [14.8%] vs 8 of 14 patients [57.1%], respectively), and those were directed toward solid tumors and new agents. CONCLUSIONS:Efforts to improve low CCT enrollment among AYAs should be differentiated by treatment site. In the adult setting, these efforts should be aimed at improving CCT availability by overcoming site-level barriers to opening existing CCTs.
