Background/Aims Multiplication of α-fetoprotein, des-γ-carboxy prothrombin, and tumor volume (ADV score) is a surrogate marker for post-resection prognosis of hepatocellular carcinoma (HCC). This study aimed to validate the predictive power of the ADV score-based prognostic prediction model for patients with solitary huge HCC.
Methods Of 3,018 patients, 100 patients who underwent hepatic resection for solitary HCC ≥13 cm between 2008 and 2012 were selected.
Results The median tumor diameter and tumor volume were 15.0 cm and 886 mL, respectively. Tumor recurrence and overall survival (OS) rates were 70.7% and 66.0% at one year and 84.9% and 34.0% at five years, respectively. Microvascular invasion (MVI) was the only independent risk factor for disease-free survival (DFS) and OS. DFS and OS, stratified by ADV score with 1-log intervals, showed significant prognostic contrasts (P=0.007 and P=0.017, respectively). DFS and OS, stratified by ADV score with a cut-off of 8-log, showed significant prognostic contrasts (P=0.014 and P=0.042, respectively). The combination of MVI and ADV score with a cut-off of 8-log also showed significant prognostic contrasts in DFS (P<0.001) and OS (P=0.001) considering the number of risk factors. Prognostic contrast was enhanced after combining the MVI and ADV score.
Conclusions The prognostic prediction model with the ADV score could reliably predict the risk of tumor recurrence and long-term patient survival outcomes in patients with solitary huge HCCs ≥13 cm. The results of this study suggest that our prognostic prediction models can be used to guide surgical treatment and post-resection follow-up for patients with huge HCCs.

A 59-year-old male patient visited ER complaining of persistent pain in his right upper quadrant abdomen. He had suffered
from end stage renal disease secondary to long-term hypertension and had been under the maintenance hemodialysis for 13
years. Half a month ago, he recognized a mass at his epigastric area. He did not have any history of liver disease in his
lifetime. Physical exams revealed that he had a tender and hard mass on his right upper quadrant and epigastric area. Total
bilirubin was 0.6 mg/dL, AST/ALT was 59/75 IU/L, and AFP was 105,740 ng/mL. Computed tomography showed the huge
liver mass in the left lobe and its size was estimated about 16cm. The regional lymph node was also found in the porta
hepatis area. He received complete resection of the hepatoma and was discharged. We concerned about high probability of
recurrence because of the pre-operative AFP level and vascular invasion in the pathologic specimen.
