AIMS: To compare the prognostic efficacy of the 5th and 6th edition of the TNM staging system for HCC. METHODS: We retrospectively applied the old and the new systems to 393 resected patients, comparing the efficacy of both in prognostic evaluation. RESULTS: The 1-, 3- and 5-year overall survival rates were 89.7, 71.1 and 56.3%, respectively. The 1-, 3- and 5-year disease-free survival rates were 79.4, 54.6 and 39.4%, respectively. Among the factors evaluated, Child's grade B and C (p=0.001) and presence of multiple nodules (p=0.01) were found to be related either to a worse long-term survival or to a worse disease-free survival. Stratifying patient survivals according to the old TNM system, we found significant differences only between stages II and IIIA (p=0.001); otherwise stages I and II (p=0.9) as well as stages IIIA and IVA (p=0.9) showed similar survival rates.

RESULTS: The 1-, 3- and 5-year overall survival rates were 89.7, 71.1 and 56.3%, respectively. The 1-, 3- and 5-year disease-free survival rates were 79.4, 54.6 and 39.4%, respectively. Among the factors evaluated, Child's grade B and C (p=0.001) and presence of multiple nodules (p=0.01) were found to be related either to a worse long-term survival or to a worse disease-free survival. Stratifying patient survivals according to the old TNM system, we found significant differences only between stages II and IIIA (p=0.001); otherwise stages I and II (p=0.9) as well as stages IIIA and IVA (p=0.9) showed similar survival rates.
