Abstract
Purpose
Large primary liver cancer (PLC) more than 10 cm in diameter is not infrequently encountered in clinical practice. This study evaluated the clinicopathological features and long-term results after surgery for large PLC.
Methods
Comparison of clinicopathological data between patients with PLC ≥10 cm (n=1,227) and PLC <10 cm (n=2,349) during the same period.
Results
In comparison with patients with PLC <10 cm, patients with PLC ≥10 cm were significantly younger (P<0.01), had a lower incidence of asymptomatic tumors (9.1% vs 39.5%, P<0.001), higher α-fetoprotein levels ( >400 ng/ml, 78.3% vs 49.2%, P<0.001), higher γ-glutamyl transpeptidase levels ( >6U, 87.7% vs 70.5%, P<0.001), a lower incidence of a history of hepatitis (45.0% vs 61.4%, P<0.001) and associated macronodular cirrhosis (cirrhotic nodules ≥0.3 cm, 59.8% vs 66.6%, P<0.001), poor differentiation of tumor cells (Edmondson grade 3–4, 24.3% vs 19.7%, P<0.01), a lower percentage of single nodule tumors (59.9% vs 75.4%, P<0.001) and well-encapsulated tumors (28.5% vs 62.1%, P<0.001), a higher proportion of tumor emboli in the portal vein (20.5% vs 9.0%, P<0.001), a lower resection rate (50.6% vs 86.8%, P<0.001), a lower curative resection rate (54.8% vs 78.3%, P<0.001), a higher operative mortality rate (4.5% vs 2.3%, P<0.001), and less local resection (52.5% vs 80.2%, P<0.001). The 5- and 10-year survival rates after resection were 26.2% and 17.5%, respectively, for patients with PLC ≥10 cm (n=621), and 54.3% and 39.5%, respectively, for patients with PLC <10 cm (n=2039) (P<0.01).
Conclusions
Large PLC had specific clinicopathological features. Surgery is the first choice of treatment. In selected patients, resection is safe and offers the chance of long-term survival. Large PLC does not exclude the possibility of cure.
