Comparison of the treatment results of involved-field and elective nodal irradiation in locally advanced esophageal cancer

摘要

In recent years, concurrent chemoradiotherapy (CCRT) has become a standard treatment modality for patients with locally advanced esophageal cancer. On the other hand, there is no international consensus regarding an accurate definition of the clinical target volume (CTV). This study evaluated the clinical outcomes in patients with locally advanced esophageal cancer treated definitively with either (ENI) elective nodal irradiation or (IFI) involved-field irradiation.
