Abstract: | Radiation therapy in early glottic cancer offers an excellent cure rate with preservation of voice. This study is an analysis of 25 (18%) patients who had failures after irradiation. Ten patients were in stage I (T1N0M0) and 15 patients in stage II (T2N0M0). All patients received megavoltage irradiation with an average dose of 6600 rad, 180 to 200 rad per day, 5 days in a week. Of the failures, 15 patients had the tumor controlled by salvage surgery, laryngectomy being the most common surgical procedure. The median time to recurrence was 23 months. A detailed analysis of the failures, along with a literature review, is done in this paper. |
