Prognostic value of resection margin for LC and OS with or without EBRT (univariate analysis)
EBRT + IOERT IOERT alone EBRT + IOERT IOERT alone
3-y-LC 3-y-LC 3-y-OS 3-y-OS
R0 83% 79% 72% 100%
R1 52% 29% 43% 31%
R2 13% 21% 53% 17%
p-value <0,001 0,028 0,011 <0,001

LC: local control, OS: overall survival, EBRT: external beam radiation therapy, IOERT: intraoperative electron radiation therapy, 3-y-LC: three-year local control, 3-y-OS: three-year overall survival, R0: complete resection without microscopic residual disease, R1: microscopic residual disease, R2: gross residual disease, %: percentage.
