Abstract
There is at present considerable controversy regarding the appropriate management of a patient who presents with a T3N0M0 glottic carcinoma. This paper presents the results for 141 patients presenting clinically with T3N0M0 glottic carcinoma between 1964 and 1981 and treated with primary radiotherapy reserving surgery for residual or recurrent disease. The actuarial survival for the entire group of patients was 50.5% at 5 yr; 28% of the patients died of glottic cancer. The local relapse-free rate achieved with radiotherapy was higher in female patients (68%) than male patients (41%) (P = 0.04); the local relapse-free rate was higher in males 60 yr of age or older (46%) than in males 59 yr of age or younger (31%) (P = 0.02). Involvement of all three laryngeal regions and initial tracheotomy were associated with a high primary failure rate. Fifty-nine per cent of patients alive at 5 yr retained an intact and functioning larynx. The time up until diagnosis of recurrence and the number of endoscopies required to establish recurrent or residual disease were all assessed with respect to their effects on survival and were shown to have no significant impact. Methods of improving the results of treatment for those patients with a high primary failure rate following radiotherapy are discussed.
