This is Episode 27: Early Glottic Cancer Fields, Fractionation, and Voice Preservation. Early glottic cancer represents the prototype of a radiation-curable malignancy. It is one of the few oncological sites where we routinely achieve patient cures through radiation therapy alone, preserving the organ while attaining functional outcomes that surgery often fails to match. For T1 glottic cancer, 5-year local control rates exceed 90%. For T2 disease, we still achieve 70-80% local control with radiation alone, and salvage laryngectomy remains an option for those who experience recurrence. The key to differentiating successful residents from their less-accomplished peers lies in understanding the rationale behind specific fractionation schemes, the reasons for neck sparing, and the methodology for designing fields that adequately cover the disease while avoiding underdosing the anterior commissure or overdosing posterior structures. Today, we will comprehensively address all these aspects. Upon completion of this episode, listeners will be equipped to accurately stage early glottic cancer, prescribe optimal fractionation, design classic opposed lateral fields, and counsel patients regarding anticipated voice outcomes.
