title: Prognostic factors in squamous cell carcinoma of the larynx.
abstract: One hundred fifty-two patients with squamous cell carcinoma of the larynx were studied. The disease-free survival and overall survival rates were correlated to 12 variables. Seven of them seemed to affect survival. Poor prognosis was related to (1) advanced stage of disease at diagnosis, (2) cord fixation and massive local invasion, (3) ulceration of the primary tumor, (4) lymph node metastases at diagnosis, (5) glottic lesions had a poorer prognosis than supraglottic ones, (6) locoregional recurrences, and (7) male gender. However, most of these significant differences were in disease-free survival, and only primary tumor staging; lymph node status; and locoregional recurrences affected overall survival. On the other hand, the other five variables showed no effect on either disease-free or overall survival rates. These included age, race, cell differentiation, type of recurrence, and the initial definitive therapeutic modality.
