A histological classification and grading of malignancy was evaluated on the initial biopsy specimens from 47 cases of squamous cell carcinoma of the tongue, which were treated by radiotherapy, chemotherapy and surgery in the Oral and Maxillofacial Surgery Department of Kyoto University Hospital from 1973 to 1988. The clinical stages of these cases were defined as follows: six cases were classified as stage I, 15 cases as stage II, 20 cases as stage III and six cases as stage IV. Theer 5-year cumulative survival rates were 100%, 73.3%, 56.1% and 83.3%, respectively, with an average of 71.3%. All cases underwent neck dissection. Group of pN (-) showed a 5-year survival rate of 83.1% and pN (+) group showed a survival rate of 25.0%.<BR>The method employed for histological malignancy grading was that proposed by Anneroth (1987), and the average of their total scores was 13.2±3.6. The materials were classified into three groups: low malignant group (≤9), moderate malignant group (10≤, ≤16) and high malignant group (17≤), and the 5-year cumulative survival rates of these groupes were 100%, 84.0% and 13.3%, respectively.<BR>There was a valid statistical significance in the survival rates within six histological parameters. A close correlation was found between the prognosis and following parameters: "pattern of invasion", "nuclear polymorphism" and "lympho-plasmocytic infiltration". But no statistical significance was found between the parameter of the "number of mitoses" and the prognosis.
