This is the first Korean evidence-based clinical practice guideline for pediatric hepatoblastoma. Key recommendations include computed tomography and magnetic resonance imaging for PRETEXT (PRE-Treatment EXTent of disease) staging, cisplatin monotherapy for standard-risk disease, upfront surgery for resectable tumors, metastasectomy for residual lung lesions, and sodium thiosulfate for otoprotection. Well-differentiated fetal histology carries a favorable prognosis, whereas the small cell undifferentiated pattern requires immunohistochemical and molecular testing to exclude malignant rhabdoid tumor.
