In 2022, 11 hospitals reported adjuvant RT cases after resection (66 patients), 4 hospitals reported neoadjuvant RT cases before surgery (80 patients), and 16 hospitals reported definitive RT cases for locally advanced PC (197 patients). Adjuvant RT dose and fractionation varied across institutions, either conventional (45\u201354\u2009Gy in 25\u201330 fractions) or hypofractionated (37.5\u201345\u2009Gy in 15 fractions) regimen. Definitive RT indications included progressive disease or an increase in tumour markers during systemic therapy (12 responses), incomplete systemic therapy due to treatment\u2010related adverse event (10 responses), ineligibility for multiagent chemotherapy due to patient performance including old age or comorbidities (9 responses), planned RT after completion of chemotherapy according to the institutional protocol (3 responses), and ineligible for conversion surgery despite the completion of chemotherapy (3 responses). The application of RT techniques and dose\u2010fractionation schedules also varied depending on the available equipped machine, tumour location, and relationship with neighbouring organs at risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Current analysis showed significant heterogeneity in the practice patterns of RT for PC in Korea, particularly in dose fractionation schedules and RT indications.
