One hundred and one patients of less than seventy years old with T1, T2 and N0 carcinoma of the tongue were graded according to the Jacobson-Yamamoto's grading (1-4 D). All patients were also classified into two groups such as less than fifty years old group and fifty to seventy years old group. Patients with grade 3, 4 C and 4 D carcinoma had more metastases to the cervical lymph nodes than grade 1, 2. Patients with T2N0 carcinoma showed approximately same five year cervical lymph node metastases free survival rate. However, the five year survival rate of less than fifty years old group was significantly lower than that of fifty to seventy years old group. In T2N0, grade 3-4 D carcinoma cases, more dead cases were found in less than fifty years old group than in fifty to seventy years old group.
101例年龄小于70岁的舌T1、T2及N0期癌患者根据雅各布森 - 山本分级法（1 - 4 D级）进行分级。所有患者还被分为两组，即小于50岁组和50至70岁组。3级、4 C级和4 D级癌患者发生颈部淋巴结转移的情况比1级、2级患者更多。T2N0期癌患者的五年颈部淋巴结无转移生存率大致相同。然而，小于50岁组的五年生存率显著低于50至70岁组。在T2N0、3 - 4 D级癌病例中，小于50岁组的死亡病例比50至70岁组更多。
