title: [Prognostic factors in supraglottic laryngeal cancer: a review of 74 cases].
abstract: Laryngeal carcinoma is a frequent neoplasm in Spain, constituting about 5.6% of all malignant tumors. The supraglottic location is more frequent than either glottic or subglottic sites. Prognostic factors were analyzed in a series of 74 supraglottic laryngeal carcinomas. Two statistical methods were used. Firstly, Cox regression, a multivariate analysis that defines a survival function of the patients, was used to detect variables with prognostic influence. Secondly, mortality tables were studied for all of them. This univariate method is used to determine the number of patients for every option of a study variable and their survival. The most important prognostic variables in our series were: tracheostomy before surgery, pathological study of the cervical nodes, time from surgery to radiotherapy, type of biopsy, and alcohol use.
