title: [Histological malignancy grading of oral squamous cell carcinomas].
abstract: A modification of Jakobsson's criteria that determines the mode of cancer invasion (Yamamoto, 1982) has been reported to be useful in predicting the prognosis in patients with an oral squamous cell carcinoma. In this retrospective study, a five-factorial grading system of the histological malignancy (+ the differentiations, the nuclear polymorphism, the mitoses, and the cellular response) was evaluated in relation to clinical course of each patient.
  
  
  RESULTS
  75 cases were classified into four grades from Grade 1, the lowest malignancy, to Grade 4, the highest malignancy. The percentage metastases was 10, 24, 54, and 75% for each grade, respectively. The percentage of survival was 75, 75, 35, and 25% for each grade, respectively. From these results, this grading system was seen to have a close-correlation with the clinical course of each patient.
