    PurposeThe aim of this study was to understand the practice patterns of palliative radiation therapy for bone metastasis in Korea among Korean radiation oncologists by survey and to determine the decision factors affecting the prescription of radiation therapy fractionation schedules.MethodsAn Internet-based survey was performed from October 5 to October 23, 2009, among 177 active full members of the Korean Society for Radiation and Oncology (KOSRO). The survey questionnaire included general information about the respondent, three types of clinical scenario, depending on the life expectancy of the patients, and the decision factors that affected the prescription of a radiation therapy schedule.ResultsThe most prescribed schedule was 30 Gy in 10 fractions regardless of the life expectancy of the patient. Also, it was found that a single fraction was seldom prescribed routinely in Korea. An increasing number prescribed fewer than 10 fractions as the life expectancy shortened; however, the prescription rate of a single fraction was still low. The general performance (and/or accompanying diseases) of patients and the life expectancy were the most considered factors in deciding the prescription of radiation therapy.ConclusionsDespite the abundant evidence supporting the equivalence of single- and multi-fraction radiation therapy, still, most Korean radiation oncologists continue to prescribe multi-fraction schedules depending on the general performance and life expectancy of the patients. Thus, we confirmed that there was a gap between evidence and practice, and treatment prescriptions can be strongly affected by decision factors other than published literature results.
