Abstract：Objective To preliminarily evaluate the efficacy and safety of intensity-modulated radiotherapy (IMRT) in the treatment of inoperable stage ⅣA thymoma. Methods A retrospective analysis of 15 patients with inoperable stage ⅣA thymoma receiving IMRT from January 2010 to December 2017 was performed. Among them, 9 patients were male and 6 female,aged 31-83 years with a medianof 59 years. The dose of radiotherapy was 50Gy/60Gy/70Gy/15-20 fractions for PTV/CTV/GTV. The short-term efficacy,overall survival rate and adverse reactions were analyzed. Results The follow-up rate was 100%. The median follow-up time was 48 months. The short-term partial remission rate was 93%(14/15). The 1-,3-and 5-year overall survival rates were 100%,75% and 75%,respectively. One patient presented with grade 3 hematological reaction. Four patients died of tumors.Conclusion Preliminary findings demonstrate that IMRT is an efficacious and safe treatment of stageⅣA thymoma, which can be applied for patients with unresectable thymoma.
