PURPOSE: Under-enrollment in clinical trials significantly limits valid analyses of clinical interventions and generalizability of findings. Often it results in premature study termination, with estimates of 22% to 50% of clinical trials terminated due to poor accrual. Currently, there are limited reports addressing the influence of race/ethnicity and socioeconomic status on clinical trial enrollment in adult glioma patients. The goal of this study was to test the hypothesis that race and socioeconomic status negatively impact therapeutic clinical trial enrollment. METHODS: 988 adult patients were identified from the UCSF Tumor Board Registry and analyzed to determine the rate of therapeutic clinical trial screening and study enrollment. RESULTS: At initial diagnosis, 43.6% and 17.5% of glioma patients were screened and enrolled in a therapeutic clinical trial, respectively. At recurrence, 49.8% and 26.3% of patients were screened and enrolled in a clinical trial, respectively. Thirty-three percent of the study population belonged to a NIH-designated underrepresented minority group; Asian/Pacific-Islander comprised 19.6% of the overall cohort. On univariate analysis, only in-state location, distance to the hospital, and WHO grade were associated with enrollment at initial diagnosis and recurrence. Minority status, insurance type, median household income, and percent below poverty were not associated with clinical trial enrollment. CONCLUSION: Minority and socioeconomic status did not impact adult glioma clinical trial enrollment. Proximity to the tertiary care cancer center may be an important consideration for minority patients. Patient screening should be carefully considered in order to avoid bias based on minority and socioeconomic status.
