Hepatic resection in adolescent and young adult patients with hepatocellular carcinoma

Figure 1 Survival curves of the adolescent and young adult (AYA) and non-AYA groups. A: Overall survival curve for patients in the adolescent and young adult (AYA) and non-AYA groups; B: Recurrence-free survival curve for patients in the AYA and non-AYA groups. AYA: Adolescent and young adult; HCC: Hepatocellular carcinoma.

Figure 2 Abdominal computed tomography images demonstrating a 10-cm tumor in segment 6 of the liver. A slightly strong uptake of the contrast agent was observed in the hepatic arterial phase, and the lesion became isodense during the portal venous, hepatic venous, and equilibrium phases (arrows).

Figure 3 Pathological findings of the resected tumor. A: Gross specimen showing a 100-mm × 80-mm lesion with expansive growth; B: Histological examination revealing moderately differentiated hepatocellular carcinoma without vascular invasion (pT1bN0M0, pathological stage IB; Union for International Cancer Control, 8^th edition).

Figure 4 Positron emission tomography findings demonstrating pulmonary metastasis (arrow). A: Plane computed tomography (CT) image; B: Positron emission tomography (PET)-CT axial image; C: Coronal PET-CT image.

Figure 5 Pathological findings of the pulmonary lesion. A: Resected lung specimen; B: Histopathological examination confirming pulmonary metastasis from hepatocellular carcinoma.
