title: Prognostic significance of STNMP and velocity of tumor growth in oral cancer.
abstract: Regression analysis using actuarial life tables has been applied to the STNMP system for the grading and staging of oral cancer. Based on 170 patients, the five-year survival figures were 78% for Stage 1, 67% for Stage 2, 36% for Stage 3, and 20% for Stage 4. This represents a considerable improvement in prognostic differentiation over existing TNM system applied to the same cohort of patients. A further variable, velocity of tumor growth, was also assessed and shown to be of value in predicting the ultimate survival of the patients.
