[Dependence of survival of patients with laryngeal cancer on several clinical and morphological factors characterizing regional metastases].
The frequency of regional metastases as a function of tumor localization in the larynx was identified. The prognostic relevance of various clinical parameters characterizing regional metastases in the vestibular compartment of the larynx was evaluated. The factors that affected the survival rate to the greatest extent were found to be: size and number of regional metastases, their displacement relative to the adjacent anatomical structures, development of contralateral and bilateral metastases, neoformations in the nodes of the lower third of the neck. It was demonstrated that the symbol N was well correlated with the survival rate. The prognostic relevance of lymph node lesions (N+R+) and lymph vessel embolism (N+E+) was ascertained for the first time in the Soviet literature. Both parameters were found to exert a significant effect on the survival rate. The occurrence of one of the morphological parameters dictates the necessity of post-operative radiotherapy of the neck region.
