    • Abstract

    Background:
    Stereotactic ablative radiotherapy (SABR) is an emerging effective technique for early stage lung cancer. We investigated the current practice patterns for stereotactic ablative radiotherapy (SABR) for lung cancer in Korea.
    
    Methods:
    A nationwide survey about experience with SABR for lung cancer was sent by e-mail to the radiation oncologists of 85 institutions in May 2014. SABR was defined as hypofractionated radiotherapy (1–8 fractions). The survey contained 23 questions, and those regarding technical details allowed multiple choices.
    
    Results:
    Of the 59 institutions that responded to the survey, 33 (56%) had used SABR for lung cancer. Thirty-seven radiation oncologists from these 33 institutions responded to the survey. Seventy-five percent of the oncologists had been treating lung cancer with SABR for less than 5 years, while 89% treat less than 20 cases annually. The most common planning method was rotational intensity-modulated technique (59%), followed by static intensity-modulated technique (49%). A wing board (54%) was most frequently used for immobilization, followed by the vacuum lock system (51%). Respiratory motion was managed by gating (54%) or abdominal compression (51%), and 86% of the planning scans were obtained with 4-dimensional computed tomography. More than half of the respondents (62%) treated daily if a multi-fraction regimen was used.
    
    Conclusion:
    The results of our survey indicated that SABR for lung cancer is being used increasingly in Korea, and that the majority of radiation oncologists using this therapy have limited experience in its use. There was wide variation among institutions with regard to the technical protocols, which indicates that standardization is necessary prior to the initiation of further nationwide multi-center, randomized studies.
