e17567 Background: The rate of patients enrolled in clinical trials (CT) is one of the main indicators of clinical research and care activity. The successive French Cancer Plans (2003-2007 and 2009-2013) aimed at quantifiable targets of patients to be enrolled in high-quality clinical trials. To help investigators achieving this objective, a substantial financial support for clinical research associates (CRA) recruitment was given to University Hospitals (UH), Comprehensive Cancer Centers (CCC) and public or private community hospitals (CH). In the meantime, significant public investment was allocated to competitively selected academic projects through the Clinical Research National Program. Methods: From 2006 to 2011, we carried out annual national surveys on clinical research activities in oncology in France. A questionnaire was sent to cancer care institutions. Number of CT open for enrolment, number of CT sponsored by the institution, number of patients enrolled and human resources (CRA) were collected. Academic and industry-sponsored trials were analyzed separately. Results: We showed that the number of patients enrolled in CT increased continuously over this period: from 21,500 in 2002 to 35,400 in 2011 (+47%). Based on these figures and assuming that there were 420,000 to 472,000 patients eligible for CT over this period, the enrolment rate for patients in CT is estimated to be 7.5 to 8.5% in 2011 versus 5.8 to 6.7% in 2003. Nearly 80% of all enrolled patients were recruited in academic CT; over 75% of patients in therapeutic trials. UH and CCC equally contributed for 80% of enrolment, CH for the residual 20%. At last, the number of CT increased by more than 35% over the same period, while the number of CRA was multiplied by 3 over the French territory. Conclusions: Our results show that public intervention for improving enrolment to cancer CT seems to be efficient. Other types of intervention are being considered, i.e., targeted on investigators, on patients, or on both. Future work should also consider the impact of CT enrolment on patients’ outcome.
