Early hepatocellular carcinoma (HCC) has been defined as a well- differentiated cancer containing Glisson's triad, but it remains unknown whether this lesion is curable. We prospectively studied 70 patients (enrolled from 1,172 referrals between 1982 and 1991) who had a diagnosis of a single HCC 2 cm or less in diameter (Stage T1) and who underwent curative hepatectomy and long-term follow-up (range, 0.2 to 14.3 years). Patients were eligible for surgery if they had a tumor that met the diagnostic criteria for HCC and were in Child-Pugh class A (n = 59) or B (n = 11) status. Among the 70 patients, there was 1 operative death. Based on our typing system, the tumors were assigned as early HCC (n = 15), overt HCC (n = 52), and non-HCC tumor (n = 3). The rate of microscopic regional spread was lower in early HCCs than in overt HCCs (7% vs. 42%; P = .01). The early HCC group had a longer time to recurrence than did the overt HCC group (3.9 vs. 1.7 years; P < .001) and had no local recurrence. After a median follow-up of 6.3 years, both overall survival and recurrence-free survival in the early HCC group were significantly better than those in the overt HCC group (P = .01; P = .001). In these two groups, the 5-year rates of overall survival were 93% and 54% (P = .01), and those of recurrence-free survival were 47% and 16% (P = .05), respectively; a significant survival benefit persisted over a decade (57% vs. 21%; P = .05). The early HCC group was at a lower risk of recurrence (relative risk, 0.31; 95% CI, 0.15 to 0.65; P = .002) and death (relative risk, 0.26; 95% CI, 0.09 to 0.73; P = .01) than was the overt HCC group. Early HCC is a distinct clinical entity with a high rate of surgical cure, thereby justifying its definition. It can be a lesion that corresponds to 'Stage 0' cancer in other organs.
