The management of early-stage squamous cell carcinoma (SCC) of the supraglottic larynx is still controversial. Supraglottic laryngectomy as well as irradiation alone is correlated with good oncological and functional results. In order to evaluate the results and prognostic factors influencing the successful using radiotherapy (RT), the authors performed a retrospective study of 100 consecutive T1-T2 N0 M0 cases of SCC of the supraglottic larynx, treated at a single institution between 1983 and 1992. RT was delivered with 60Co or 6 MeV photons through two lateral parallel opposed portals encompassing the primary laryngeal tumor and the upper and mid-neck nodes (Robbins' levels II, III and V). Supraclavicular nodes (level IV) were electively irradiated in 54 patients with T2 N0 tumors only, using an anterior field with midline block. Sixty-three patients received conventional fractionation (2 Gy/fraction, once-a-day, five times a week), while 37 patients were irradiated according to a twice-a-day fractionation regimen (1.5 Gy/fraction, twice a day with six-hour interval, five days a week). The median total tumor dose delivered was 67 Gy. A multivariate analysis showed that performance status, tumor grade and fractionation modality were the only statistically significant variables influencing disease-free survival. Acute and late radiation reactions were relatively low. This retrospective study confirms that conservative management of T1-T2 N0 supraglottic cancer using RT can achieve good cure rates with the possibility of larynx preservation for the majority of the patients. The decision between different conservative treatment modalities may be influenced by several factors correlated to the patient's conditions, tumor characteristics, but especially treatment modalities.
