Implementation of Comprehensive Surgical Guidelines for Hepatoblastoma

Infographic · Nov 2025 · 1 min read

In brief

The AHEP0731 trial achieved 93% resection rates in pediatric hepatoblastoma using PRETEXT-based surgical timing guidelines, with 65% adherence to protocol-recommended resection timing. While guideline nonadherence did not affect survival or complication rates, some patients underwent transplantation when partial hepatectomy may have sufficed.

AHEP0731 achieved 93% resection rate using PRETEXT/POST-TEXT imaging guidelines to time surgery after chemotherapy cycles.
65% adherence to protocol timing; early resection occurred in 21% of cases, potentially avoiding necessary transplants.
35% of patients meeting transplant criteria were not referred within recommended timeframe, risking suboptimal outcomes.
Guideline nonadherence led to unnecessary transplants in some patients who could have undergone partial hepatectomy.
No significant differences in survival or complications between adherent and nonadherent groups despite timing variations.

Objective: To evaluate the impact of surgical guidelines on the management of children with hepatoblastoma.

Background: The Children's Oncology Group study AHEP0731 was the first pediatric cooperative group trial to propose guidelines for the surgical management of children with hepatoblastoma.

Methods: AHEP0731 enrolled children with hepatoblastoma between 2009 and 2018. Surgical guidelines were based upon radiographic extent of disease (PRETEXT, POST-TEXT). Planned non-real-time central review of imaging was completed at diagnosis and after two, four, and six cycles of chemotherapy to determine guideline adherence. Resection rate, event-free survival (EFS), overall survival (OS), and complications were compared between guideline adherent and nonadherent groups.

Results: Of 226 enrolled patients, 221 were evaluable of whom 205 (93%) underwent definitive surgical resection. Guideline adherence for protocol recommended timing of resection was 65% (133/205). The nonadherent group included 44/205 (21%) patients who underwent early resection and 28/205 (14%) patients who underwent late resection or late transplantation. Eighty-five patients met criteria for early referral to a liver transplant center, of whom 55 (65%) were referred within the recommended timeframe. Twelve patients received liver transplants outside of surgical guidelines. There were no significant differences in EFS, OS, or complication rates between adherent and nonadherent groups.

Conclusions: Implementation of surgical guidelines, in combination with effective chemotherapy and radiologic staging, produced a higher rate of definitive tumor resection compared to historical trials. Nonadherence with surgical guidelines resulted in liver transplantation in some patients for whom partial hepatectomy might have been an option.
