Of the solid tumors treated by pediatric surgeons, the prognosis in cases of hepatoblastoma depends largely on whether or not complete tumor resection has been achieved by appropriated surgery. Therefore, in the design of treatment strategies for pediatric malignant solid tumors, hepatoblastoma is a representative type of tumor that requires precise operative procedure. Basic hepatectomy refers to "systematic hepatectomy." Historically, surgery for pediatric liver tumors has focused on "tumor resection." Such surgery is somewhat similar to the so-called "enucleation" and is not systematic hepatectomy, which is based on the vascular supply.
