PURPOSE: This study was performed to evaluate the efficacy and safety of dynamic arc conformal radiotherapy, a simple intensity modulated radiation therapy (IMRT), for the treatment of paraaortic lymph node @entity3 . MATERIALS AND METHODS: Twenty-nine @entity1 with paraaortic lymph node @entity3 were enrolled in this study. The total planned dose was 55-60 Gy. A computed tomography (CT) simulator was used in the treatment planning. RESULTS: The total radiation dose delivered was 50-63.4 Gy (median 60 Gy). Sixteen of 29 @entity1 showed @entity5 shrinkage on CT, and the 2 year in-field recurrence free survival rate was 58%. Acute Grade 1 and Grade 2 @entity344 occurred in 31% and 17%, respectively, and acute Grade 2 @entity409 occurred in 7%. As a late complication, Grade 1 and Grade 2 @entity409 occurred in six @entity1 (21%) and five @entity1 (17%), respectively. There was no @entity8 or @entity602 detected. CONCLUSION: Dynamic arc conformal radiotherapy, a simple IMRT, is a safe and effective treatment method for paraaortic lymph node @entity3 .
