    Abstract:
    The Authors reviewed a group of 28 pts with early-stage supraglottic carcinoma (T1-T2N0), classified according to UICC (1987), and treated exclusively with radiotherapy (RT) between 1980 and 1991. Until 1990 RT was employed for such tumors when surgery was refused or controindicated, while since 1991 primary irradiation (with surgery in reserve) has been considered the treatment of choice. The total dose ranged from 66 to 70 Gy on the larynx and up to 50 Gy on neck nodes. RT was applied in a daily fraction of 2 Gy five times a week. No significant early complications were observed. Only 1 pt showed residual cronical oedema in the arytenoid region. In none of the pts was tracheostomy necessary. The local control rate obtained after 30 months was 85.7% (24/28). Salvage surgery (horizontal supraglottic laringectomy, HSL) was performed in 3 out of 4 pts with local failure and achieved complete control of the disease. In the last pt the surgery was controindicated because of poor general health conditions. The actuarial survival rate after 5 years is 86.2%. The present series was compared to a group of 152 pts with T1-T2N0 supraglottic cancer treated surgically (HSL) at the same Istitution. In these pts local control and the actuarial survival rates are 85.6% and 89% respectively. According to recent Literature data, the present findings confirm that RT may be administered for the treatment of selected early stage (T1-T2N0) supraglottic squamous cell carcinoma of the larynx with oncologic results equivalent to those obtained with radical surgery. The importance of imaging techniques (TC, MRI) in the correct staging of the tumor is emphasised.
