Abstract

Between 1987 and 1993, 36 patients with early squamous cell carcinoma of the larynx (I-II stage) were treated with radiotherapy, at the National Institute for Cancer Research of Genoa; 25 patients were stage I (5 T1N0 of supraglottic larynx, 15 T1aN0 and 5 T1bN0 of glottic larynx) and 11 patients stage II (7 T2N0 of supraglottic larynx and 4 T2N0 of glottic larynx); there were 32 males (89%) and 4 females (11%), ages ranging from 34 to 83 years (mean age 61 years). The radiotherapy was performed utilizing the X-ray of a 6 MV linear accelerator, with a daily conventional fractionation and a dose of 66-70 Gy/33-35 fr./7 weeks, with co-axial latero-lateral beams including cervical lymph-nodes, except for T1N0 glottic cancer. The median follow-up was 51 months (range 8-84 months). The local control rate of all the patients was 80.5% at 51 months. According to the stage and tumor subsite, it was 80% for stage I a-b of the glottic site, 60% for the stage I of supraglottic site, 91% for stage II of supraglottic and glottic site. Only 6 patients (18%) underwent the salvage surgery and in all the patients the illness was under control. The overall survival rate was 83.3% at 51 months (4 patients died of a second tumor (11%) and 2 from heart disease (5.5%)). The only complication we observed was a glottic edema. The analysis of our results demonstrates that radiotherapy seems to be more appropriate in the T1a-b glottic cancer. These results are in agreement with those obtained by other studies. On the contrary, the results obtained with radiotherapy, in the T2N0 glottic cancer, are not satisfactory, with regard to local control, as those obtained with surgery, but offers best functional results. In most T2N0 tumors, after the failure of radiotherapy, a reconstructive laryngectomy is still possible. We also obtained good results with the supraglottic lesions. The small number of cases we treated does not allow us to achieve final conclusions and other studies are necessary to confirm our results.
