[Prognostic value of the degree of differentiation and the peri-tumor lymphoid infiltration in epidermoid carcinoma of the larynx]. / Valor pronóstico del grado de diferenciación y el infiltrado linfoide peritumoral en el carcinoma epidermoide de laringe.

By multiple linear regression the authors show a closed relationship between survival and conventional anatomopathologic data as grade of differentiation and of lymphoid infiltration of the primary tumor. This retrospective pathological study showed that various degrees of squamous cell differentiation may be recognized for malignant laryngeal lesions and that such distinction may be of prognostic significance.
