Foote's letter thoughtfully supports our contention that all T1 tumors are not the same. Our most recent published series of open operations describes the results of surgery for certain T1 invasive glottic cancers that were not amenable to endoscopic removal. These tumors usually involved the majority of one vocal cord, the anterior commissure, and a portion of the opposite cord. Reports of radiation therapy for T1 glottic carcinoma use different radiation treatment approaches and include a wide spectrum of cancers: in situ tumors, superficially microinvasive lesions, invasive tumors, cancers previously removed at the time of biopsy, midcord cancers, tumors that involve the anterior commissure area, or lesions that involve both vocal cords.
In actuality, the comparison of our institution's results of open operations and radiation therapy for early glottic carcinoma was largely comparable. All the recurrences after radiation therapy occurred in patients whose lesions would have been amenable to an
