Comparison of clinicopathological characteristics between HBV-HCC and HCV-HCC cases.
| Characteristics | Group | HBV-HCCa, median (range) | HCV-HCCb, median (range) |
|---|---|---|---|
| Tumor size (cm) | IFN | 3.9 (2.5–5.5) | 2 (1.5–3.4) |
| Control | 3.95 (2.1–5.7) | 2.1 (1.5–2.6) | |
| Multiple tumors (%) | IFN | 17.5 (17–21.5) | 27.2 (10–43.8) |
| Control | 15.9 (12.7–27) | 25.7 (10–37.5) | |
| Vascular invasion (%) | IFN | 48 (30.8–76.2) | 19.7b |
| Control | 35 (24.4–75.4) | 23b | |
| Cirrhosis (%) | IFN | 53.8 (48–83) | 90 (47–100) |
| Control | 83 (44.2–88.1) | 90 (53–100) |
a
Patients with HBV-HCC had larger tumors, less multiple tumors, more tumors with vascular invasion and less severe liver cirrhosis.
b
Only the study by Mazzaferro et al (4) was included because information regarding vascular invasion in other studies was unavailable.
HBV, hepatitis B virus; HCC, hepatocellular carcinoma; HCV, hepatitis C virus; IFN, interferon.
