Later that year the ICRU published report 91 about prescribing, recording and reporting of stereotactic treatments. The purpose of this multicentre study is to quantify the current variation in prescription practice in the institutions that contributed to the ACROP guideline and to establish the link between ACROP and ICRU91 recommendations. Methods From each of the eight participating centres, 15 consecutive clinical treatment plans of patients with peripherally located early stage NSCLC were selected.
