[Descriptive study of cancer of the cavum, especially of epidermoid carcinoma (III)]

Five-year survival (5-YS) a) Age: 77, 45, 35, 35 y 28%. The 65 and 50% arise to 15 and 18 m. b) Gender: 5-YS was higher for women (31%) than for man (22%). c) Age groups: 0-40 y (52%), 41-60 y (40%), older than 60 y 14%. d) Stage (tumor): T-1 + T-2: 92, 69, 61, 61 and 46%. T-3 + T-4: 61, 22, 17, 11 and 11%. Nodal Neck: N-0 + N-1: 70, 45, 35, 35 and 17%. N-2 + N-3: 93, 53, 53, 40 and 40% e) Hazard function: is greatest for T-3 + T-4 than T-1 + T-2 (3.2-3.5: 1). f) Histological subtypes: The 5-YS was higher for undifferentiated than squamous carcinoma (p greater than 0.05). g) Recurrences and distant metastases: The greatest survival was noted for patients with recurrences while the poorest was in the metastases.
