*
Denotes that a patient was taken to the operating room, but surgery was not necessarily performed.
Abbreviations: SBRT, stereotactic body radiation therapy; HIGRT, hypofractionated image-guided radiation therapy; N, number; R0, margin negative resection; R1, microscopically positive margin; R2, grossly positive resection margin.
