A clinicopathological study was made of the correlation between histological findings of the biopsy specimen and local cure rate of 60 cases of oral squamous cell carcinoma treated with interstitial irradiation. The following findings were obtained.<BR>1. Local cure rate with interstitial irradiation was 82% in Ti cases, 83% in early-T2 (21-30 min) cases, 64% in advanced-T2 (31-40 mm) cases, and 25% in T4 cases.<BR>2. Moderately or poorly defferentiated type showed lower local cure rate than well differentiated type.<BR>3. Diffuse invading type showed lower local cure rate than clear borderline type.<BR>4. These results suggest that the application of interstitial irradiation should be decided in view of histological findings as well as TNM classification.
