title: [Interstitial radiotherapy of carcinoma of the tongue-comparison between Jacobson-Yamamoto grading and prognosis].
abstract: 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.
