Purpose Treatment protocols in pediatric oncology have historically known high accrual rates, up to 94 %. Accrual for supportive care studies on the other hand appears to be a challenge. The aim of this study was to search for reasons explaining this poor accrual and for possible interventions to improve patient enrolment. Methods The failure screen log of our supportive care study (the Aristocaths study) was analyzed, and subsequently, a literature search was performed. Results The literature search (1985-2011) revealed three factors that can influence accrual. Firstly, study implementation and patient enrolment can be facilitated by appointing a dedicated clinical investigator in all participating centers and by facilitating clinical research nurses. Furthermore, adequate and tailor-made information is required for families to make a well-informed decision regarding study participation. Lastly, sufficient time should be assured for the process of decision making, especially since the number of eligible studies is increasing rapidly. Concerning our study, all three elements were met, but the most striking finding was the presumed burden of study participation by the majority of parents (82 %) as the main argument against randomization. Conclusions Accrual of pediatric oncology patients in supportive care studies is challenging. Nevertheless, welldesigned randomized controlled trials in supportive care will be essential for the improvement of pediatric cancer care. Therefore, we will need to increase awareness through (inter)national supportive care working groups regarding the need for supportive care trials and stimulate accrual when such trials are open.
