A multivariate analysis with a logistic regression model was performed in 181 cases of patients affected by laryngeal cancer, in order to evaluate the histologic tumor factors in predicting metastatic risk. The patterns used were: grading, localization, extension to the extralaryngeal structures, mode of growth.

Cancer extended to the extralaryngeal tissues and with "infiltrating" type of growth are significantly correlated with nodal involvement.

Abstract

A multivariate analysis with a logistic regression model was performed in 181 cases of patients affected by laryngeal cancer, in order to evaluate the histologic tumor factors in predicting metastatic risk. The patterns used were: grading, localization, extension to the extralaryngeal structures, mode of growth. Nodal metastases are less influenced by the localization and the differentiation grade of the tumor. Cancer extended to the extralaryngeal tissues and with "infiltrating" type of growth are significantly correlated with nodal involvement. Multivariate analysis seems to be the best method to identify the exact value of each histological parameter used in prognosis of laryngeal carcinoma.
