EDITORIAL Defining the Role of Hemithorax Irradiation for Thymomas Is Difficult Steven E.

This was done to clarify the role of EHRT. Following removal of disseminated lesions, EHRT was given to 12 patients with pleural dissemination using doses of 11.2 to 16 Gy in 7 to 10 fractions (mean dose: 14.1 Gy).
