FIG A1. — Tumor and extent of portal vein tumor thrombus (PVTT) before and after neoadjuvant three-dimensional conformal radiotherapy (RT) on computed tomography scan and three-dimensional reconstructed images (with hiding of irrelevant anatomic structures) in a representative patient with partial remission to neoadjuvant RT. (A) A 55-year-old male with an original 4 × 3.5-cm hepatocellular carcinoma with PVTT (arrow), which had extensively invaded the right-side branch, bifurcation, and left-side branch of the portal vein (Cheng’s type III) before RT. (B) Four weeks after RT, tumor size shrunk to 2.5 × 2.5 cm, and the PVTT (arrow) was confined to the right side ipsilateral of the portal vein (type II).
