    • ... However, percutaneous biopsy should be used with caution, particularly in patients who are eligible for curative treatment (surgical resection or liver transplantation), because of the 2–3% risk of tumor seeding along the biopsy needle track...

    • ...].F01At the joint symposium with JSH and the International Liver Cancer Association (ILCA), the algorithm of diagnosis and treatment for HCC was discussed using Answerpad. Forty-five hepatologists, surgeons, radiologists and pathologists participated in this meeting and voted the statement. Eight important statements were discussed and voted by Answerpad. The results described compare them with those of the JSH consensus meetings.Statement 1A needle biopsy of the hypervascular HCC nodule with 1.5 cm should not be done.A typical case is shown in figure 2. A hypervascular nodule was observed at the arterial phase in a contrast-enhanced CT scan with a diameter of 1.8 cm in segment 7, which becomes a hypovascular region in the equilibrium phase. This nodule was defined as a hypervascular region during CT during hepatic arteriography (CTHA) and low-density area during CT during arterioportography (CTAP). Gadolinium (Gd)-EOB-DTPA MRI was carried out and the nodule of segment 7 became a low-intensity area in the hepatobiliary phase. A needle biopsy gives important information concerning pathological differentiation grade and biomarker expression; however, implantation of neoplastic cells to the tract or seeding has been reported [...

    • ...Clinically, HCC frequently remains silent in early stages, and symptoms such as abdominal pain, weight loss, a palpable mass or signs of decompensated liver disease such as jaundice and ascites, if not already caused by cirrhosis, become evident more likely in advanced disease. Therefore, a periodic screening of patients with chronic liver disease and cirrhosis using ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) or angiography in combination with serum analyses of α-fetoprotein (AFP) levels is recommended to diagnose asymptomatic HCCs. Although it is believed that good-quality, contrast-enhanced CT and MRI are appropriate for the diagnosis of liver tumors, the accuracy of diagnosing small malignant liver tumors (<2 cm) and the distinction of them from benign lesions, especially in cirrhotic livers, may be problematic [...
