Bottom Line: However, the portion of patients with stage B that will achieve better outcomes from surgical treatment remains unclear.Cumulative tumor size >5.0 cm and tumor number ≥4 were independent prognostic risk factors for DFS.The 1-, 2-, and 5- year DFS rates and OS rates of patients with at least one of these two factors were 49.0, 17.2, and 7.4% (for DFS), and 78.6, 54.8, and 13.4% (for OS), respectively, which were significantly lower than patients without these two factors (77.8, 58.3, and 27.2% for DFS, and 94.4, 83.3,and 51.8% for OS, respectively, P < 0.01).

ABSTRACT

Background: Although the Barcelona Clinic Liver Cancer (BCLC) staging system suggests that patients with stage B hepatocellular carcinoma (HCC) should be treated with transcatheter arterial chemoembolization instead of surgical treatment, recent studies indicated that the prognosis of surgical resection for patients with BCLC stage B HCC was better than that of TACE. However, the portion of patients with stage B that will achieve better outcomes from surgical treatment remains unclear. In this study, we identified risk factors that influence the prognosis of BCLC stage B HCC after R0 surgical resection to determine whether some patients with stage B HCC may benefit more from R0 resection than other patients and to provide a guideline to estimate the tendency.

Methods: The clinical data of 78 patients with BCLC stage B HCC after R0 surgical treatment within 11 years were analyzed retrospectively, using relapse or death as the endpoint. Kaplan-Meier survival and Cox regression analyses were used to study prognosis (disease-free survival, DFS and overall survival, OS) and independent risk factors.

Results: For all stage B patients, 1-, 2-, and 5-year DFS rates were 62.5, 36.4, and 16.6%, respectively. Cumulative tumor size >5.0 cm and tumor number ≥4 were independent prognostic risk factors for DFS. The 1-, 2-, and 5- year DFS rates and OS rates of patients with at least one of these two factors were 49.0, 17.2, and 7.4% (for DFS), and 78.6, 54.8, and 13.4% (for OS), respectively, which were significantly lower than patients without these two factors (77.8, 58.3, and 27.2% for DFS, and 94.4, 83.3,and 51.8% for OS, respectively, P < 0.01).

Conclusions: The analyses indicated that the outcomes of R0 resection were much better for patients with BCLC stage B HCC with two or three tumors and cumulative tumor sizes of ≤5.0 but >3.0 cm than other patients with stage B.

Mentions: Patients with tumor number ≥4 and cumulative tumor size >5 cm were classified as the high-risk group (42 cases) while the other 36 patients as the non-high-risk group. Kaplan-Meier survival analysis was performed to analyze the DFS. For patients in the high-risk and non-high-risk groups, the 1-, 2-, and 5-year DFS rates were 49, 17.2 and 7.4 (for high-risk), and 77.8, 58.3 and 27.2 % (for non-high-risk), respectively (P = 0.001); the OS rates at 1, 2. and 5 years were 78.6, 54.8 and 13.4 % (for high-risk), and 94.4, 83.3 and 51.8 % (for non-high-risk), respectively (P = 0.000) (Fig. 4). The significance of the analytic results was in line with those in 3.2 and 3.3 sections, i.e., the recurrence rates of the non-high-risk group were significantly lower than those of the high-risk group.Fig. 4
