Hepatoblastoma is the most common pediatric liver malignancy and usually occurs within the first 3 years of life. In recent years, the overall incidence of hepatoblastoma has exhibited the greatest increase among all pediatric malignancies worldwide. The diagnosis of hepatoblastoma may be challenging due to the lack of a current consensus classification system. The International Pediatric Liver Tumors Consensus introduced guidelines and a consensus classification for the diagnosis of hepatoblastoma as either epithelial or mixed epithelial and mesenchymal and in the updated 5th edition of the World Health Organization Classification of Digestive System Tumors.
肝母细胞瘤是最常见的儿童肝脏恶性肿瘤,通常发生在生命的头3年内。近年来,肝母细胞瘤的总体发病率在全球所有儿童恶性肿瘤中上升幅度最大。由于缺乏当前的共识分类系统,肝母细胞瘤的诊断可能具有挑战性。国际儿童肝脏肿瘤共识在世界卫生组织消化系统肿瘤分类第5版更新版中引入了肝母细胞瘤诊断的指南和共识分类,将其分为上皮型或上皮和间充质混合型。
