Postoperative brachytherapy alone and combined postoperative radiotherapy and brachytherapy boost for squamous cell carcinoma of the oral cavity, with positive or close margins

Abstract

BRT alone for SCC T1-2/N0N- is better than RT-BRT because, with equivalent results, it avoids the adverse events of postoperative RT (xerostomia) and permits the treatment of a second head and neck primary in nonirradiated tissue. The results for the T3-4/N- are acceptable with this approach (ie, RT-BRT) but may be improved for N+.
