Purpose. The aim of this study was to identify patient and physician factors related to enrollment onto Gynecologic Oncology Group (GOG) trials. Methods. Prospective study of women with primary or recurrent cancer of the uterus or cervix treated at a GOG institution from July 2010 to January 2012. Logistic regression examined probability of availability, eligibility and enrollment in a GOG trial. Odds ratios (OR) and 95% confidence intervals (Cl) for significant (p < 0.05) results reported. Results. Sixty institutions, 781 patients, and 150 physicians participated, 300/780 (38%) had a trial available, 290/300 had known participation status. Of these, 150 women enrolled (59.5%), 102 eligible did not enroll (35%), 38 (13%) were ineligible. Ethnicity and specialty of physician, practice type, data management availability, and patient age were significantly associated with trial availability. Patients with >4 comorbidities (OR 4.5; CI 1.7-11.8) had higher odds of trial ineligibility. Non-White patients (OR 7.9; Cl 1.3-46.2) and patients of Black physicians had greater odds of enrolling (OR 56.5; Cl 1.1-999.9) in a therapeutic trial. Significant patient therapeutic trial enrollment factors: belief trial may help (OR 76.9; Cl 4.9->1000), concern about care if not on trial (OR12.1; Cl 2.1-71.4), pressure to enroll (OR.27; Cl 0.12-.64), caregiving without pay (OR 0.13; Cl.02-.84). Significant physician beliefs were: patients would not do well on standard therapy (OR 3.6; Cl 1.6-8.4), and trial would not be time consuming (OR 33; Cl 13-8.1). Conclusions. Trial availability, patient and physician beliefs were factors identified that if modified could improve enrollment in cancer cooperative group clinical trials. (C) 2015 The Authors.
