No improvement in clinical trial enrollment for adolescents and young adults with cancer at a children's hospital.

We have previously published data from 2001 to 2006 showing that adolescent and young adult (AYA) oncology patients have significantly lower therapeutic clinical trial enrollment rates than younger patients. Our objective was to determine if the enrollment of AYA patients on therapeutic studies at the same institution has improved in recent years with the greater focus on this population locally and nationally. We retrospectively analyzed cancer registry data at the Children's Hospital of Pittsburgh (CHP) for all new oncologic diagnoses between January 2010 and December 2014. These data included age, gender, diagnosis, race and whether the patient was enrolled on an open treatment study. Univariate analyses were carried out to compare demographic data between AYA patients (aged 15-22) who enrolled on study and those who did not. Eight hundred sixty-five new oncology patients were seen at CHP during this time, 23% of whom were 15 years or older; 33% of all patients were treated on a clinical trial, including 34% of younger patients and 24% of older patients (P = 0.0017). The differences between these rates and those from prior years in both age groups (38% and 27%, respectively) were not statistically significant (P = 0.15, 0.53). The most common reason for the low enrollment rates was again the lack of an open therapeutic trial. Despite initiatives at CHP and on the national level to enroll more AYA patients on clinical trials, our most recent data show no improvement. This is a potentially remediable factor that needs to continue to be prioritized nationally.

Improved clinical trial enrollment in adolescent and young adult (AYA) oncology patients after the establishment of an AYA oncology program uniting pediatric and medical oncology divisions.

Since 1975, there has been a dramatic increase in the survival rates of pediatric and older cancer patients, but adolescent and young adult (AYA) patients ages 15 to 40 years have not had a similar improvement. Data indicate a direct correlation between increased cure rates and clinical trial enrollment. The authors previously published data indicating inferior clinical trial enrollment when AYA patients were treated at an adult oncology center versus a pediatric oncology center. To address this deficit, a joint pediatric and adult AYA Oncology Program was established in July 2006 with the primary objective of improving outcomes by increasing therapeutic clinical trial enrollment in this population. Patients who were referred to that program from July 2006 through June 2010 were examined retrospectively to establish whether clinical trial enrollment increased compared with historic controls. Fifty-seven patients were referred to the program from 2006 to 2010 (range, 12-16 new patients per year). Eight patients were referred for consultation only and were not treated at the University of Pittsburgh Cancer Institute or Children's Hospital of Pittsburgh. Five of 22 patients (23%) who received treatment at the pediatric cancer center were enrolled onto a clinical trial, whereas 9 of 27 patients (33%) patients who received treatment at the adult cancer center were enrolled. There was superior trial participation compared with the previous 3 years for those shared AYA patients who were treated at the adult center (P < .001). Data from this study demonstrated that establishing a unified AYA oncology program can lead to improved clinical trial enrollment for patients who are treated at medical oncology centers.

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.

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. 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. 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. 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.
