[Prognostic factors in laryngeal cancer].

A retrospective analysis of 335 patients with laryngeal and hypopharyngeal cancer from the ENT-Hospital of the Wilhelm-Pieck-University Rostock, who died to December 1986, was made. Adjusted five-year survival rates were in glottic carcinoma 54.2 per cent and supraglottic carcinoma 42.9 per cent. This is significantly higher than in carcinoma of hypopharynx with 15.4 per cent. The following prognostic factors were important for the survival rates of the patients without consideration of the therapy of primary tumor: pTNM-stage, evidence and development of regional metastasis, enlarged stage of the primary tumor at the time of diagnosis; intercurrent diseases; development of distant metastasis and/or second carcinoma; localisation of tumor; primary therapy of regional lymph nodes.
