Lack of Tumor Seeding of Hepatocellular Carcinoma After Percutaneous Needle Biopsy Using Coaxial Cutting Needle Technique

Abstract

We found no tumor seeding after percutaneous biopsy of HCC using a coaxial cutting needle technique. This rate, 0%, is lower than those reported with other techniques. The use of a needle introducer that remains in position during multiple cutting needle passes protects normal tissue along the track and may reduce seeding. This has particular importance for patients with stage I-II HCC, for whom liver transplantation may be curative.
