RESUMEN
PURPOSE: Recently, children with trisomy 18 have been receiving more active treatment for malignancies. We report herein seven cases complete resection was achieved, and discuss multidisciplinary treatment for hepatoblastoma in patients with trisomy 18. METHOD: The medical records of children with trisomy 18 who were treated at the study center between 2010 and 2023 were reviewed. RESULT: Six of 69 patients had hepatoblastoma development, and three of these underwent multidisciplinary treatment. In addition, 6 patients had been referred by another hospital for treatment, and four of these underwent multidisciplinary treatment. Among the seven patients who underwent multidisciplinary treatment, three, two, and two were categorized in Pre-treatment Extent of Disease (PRETEXT) classification group I, II, and III, respectively. Neoadjuvant chemotherapy resulting in tumor reduction was performed in three cases. In all the cases, complete resection was achieved with pathologically safe margins. Perioperative complications included circulatory failure in one case and bile leakage in two cases. Adjuvant chemotherapy was administered in four cases. The postoperative observation period ranged from 3 months to 11 years, and all the patients are recurrence-free. CONCLUSION: Children with trisomy 18 complicated with hepatoblastoma whose cardiopulmonary conditions are stable may be good candidates for chemotherapy and surgery.

Background: The principle of hepatoblastoma (HB) treatment is complete resection. The removal of tumor-bearing section(s) or hemiliver is widely accepted. However, neither the standardized anterior approach for right hepatectomy nor parenchymal sparing anatomical liver resection has been described for HB. Methods: We retrospectively reviewed the clinical course of two pediatric HB patients who underwent extended right hepatectomy using the anterior approach with the liver hanging maneuver and one who underwent parenchymal sparing anatomical liver resection of S4 apical+S8 ventral/dorsal+S7. The critical aspects of surgical techniques are described in detail. Results: In all three patients, R0 resection was achieved without complications and are currently alive without recurrence after an average follow-up of 23 months. Intraoperative cardiac hemodynamics were stable, even in a trisomy 18 patient with cardiac disease. Conclusions: Our findings suggest that these innovative techniques established in adults are safe and feasible for HB in children. These techniques also allow optimal anatomical liver resection to accomplish curative surgery while maintaining the functional reserve of the remnant liver.
