Abstract

The results were analyzed of 175 patients with glottic squamous cell carcinomas who were treated with curative purposes (1970-1986). One hundred and sixteen of them underwent surgery at the Otolaryngology Department of the University of Florence, and 59 were treated by radiation therapy at the Florence University and Hospital Departments of Radiotherapy. In the surgical series 78 cases were treated with radical surgery and 38 with conservative surgery. All patients were staged according to TNM system (UICC 1978) as T2. Overall 10-year local control rates were 74% for the surgical series and 69% for the cases treated by radiation therapy. After salvage therapy 10-year survival rates were 83% and 76%, respectively. The analysis of the results showed no statistically significant difference. In the group treated by radical surgery 80% local control was observed, versus 66% in the cases treated with conservative surgery. 10-year survival rate was higher in the latter group (89% versus 81%) because of better results of salvage therapy: 7 of 10 recurrences were salvaged with the second treatment. Several prognostic factors were evaluated, i.e., T extent, anterior commissure involvement, subglottic invasion, vocal cord mobility impairment, and ventricular involvement. Anterior commissure involvement was the main factor affecting outcome in the surgical series: in the presence of this factor, 64% 10-year local control was observed versus 85% in the patients without commissure involvement. This factor proved more important in the patients treated with conservative surgery (10-year control: 42% versus 88%) than in those undergoing radical surgery (78% versus 85%). Anterior commissure involvement and the number of involved subsites were found to worsen prognosis in the series treated by radiation therapy: cases with anterior commissure involvement had 59% 10-year local control versus 83%. The cases with a deeper spread had 60% local control versus 75%. Vocal cord mobility impairment was a less important prognostic factor in both series. Our results suggest radiation therapy as a valuable method in the treatment of the small T2 laryngeal cancers which are not suitable for conservative surgery.
