Between January 2005 and September 2009, 101 patients who underwent curative hepatectomy for primary HCC were enrolled in the study. Patients were divided into two groups: a non-MNT group (n=51), and an MNT group (n=50) that was administered 45 mg of MNT daily. During the observation period, recurrence was observed in 33 patients in the non-MNT group and in 28 patients of the MNT group (p=0.545). In patients with a preoperative Des-γ-carboxy-prothrombin (DCP) level lower than 40 AU/l (n=38), the cumulative disease-free survival rates at 12, 36, and 60 months in the non-MNT group, were 81.3%, 0.0%, and 0.0%, respectively, while those in the MNT group were 78.3%, 58.1%, and 31.0%, respectively (p=0.060). MNT has a moderately suppressive effect on HCC recurrence after hepatectomy, especially in patients with a normal preoperative DCP level.
