[Evaluation of clinical and pathological factors relating to lymph node metastasis in carcinoma of the tongue].

In this paper we adopt various clinical and pathological parameters to evaluate the factors relative to the lymph node metastasis. We are of the view that the TNM classification can not indicate the presence of the lymph node metastasis clearly. When the size of tumor is less than 2.0 cm in diameter there is almost no metastasis. Using computer, we analyse the factors and found that only the depth, pattern of growth and the degree of lymphoid cell infiltration are relative to metastasis. The coincidence is 78.6%.
