The rabbit VX2 hepatic tumor model has been widely used for the investigation of liver cancer. The present study was designed to compare two inoculation methods in order to identify an improved modality for establishing rabbit hepatic tumors. A total of 44 rabbits were randomly divided into 2 groups. All inoculations were performed by open laparotomy. In group 1,22 rabbits received a VX2 tumor cell suspension in a volume of 0.2 ml, which was slowly injected into the rabbit liver parenchyma using an 18-gauge needle. In group 2, a 0.2-ml suspension of small, minced tumor fragments of a VX2 carcinoma, inserted into an 18-gauge needle, was implanted into the liver parenchyma. The tumor survival ratio, size and extrahepatic metastases were evaluated and compared using computed tomography (CT)-scan, angiography and pathological specimens. At 2 weeks following implantation, successful liver tumor growth was achieved in 14 out of the 22 rabbits in group 1 (63.6%) and 21 out of the 22 rabbits in group 2 (95.5%) (P
