[Proliferative activity of the cells and clinico-morphological characteristics of cancer of the larynx].

Proliferative activity of tumor cells was measured in 107 patients with squamous cell carcinoma of the larynx and found to correlate with the degree of tumor differentiation, lymphoid infiltration of the stroma, extent of blood supply, and capacity for metastatic spread. A comparison of clinical and histologic findings indicated, in particular, that the labeling index correlated with the duration and stage of the disease.
