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 50 Gy/60 Gy/70 Gy/ 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 stage ⅣA thymoma,which can be applied for patients with unresectable thymoma.
