What this trial studies

This is a national, multicenter observational registry that will collect prospective data on adults undergoing techniques to induce liver hypertrophy before resection, with plans to include a retrospective cohort from the prior 10 years. Patients will receive usual local care and be followed from recruitment through their hospital stay, with vital status and events collected for up to five years after surgery where possible. The registry aims to describe trends in technique use, procedural details, and short- and long-term outcomes across participating Italian centers. Data will be used to compare historical and prospective cohorts and to characterize variation in practice and outcomes.

Who should consider this trial

Good fit: Adults (18 or older) with benign or malignant liver tumors who have a future liver remnant deemed insufficient (approximately <20–40%) and who can give informed consent are appropriate candidates.

Not a fit: Pregnant or breastfeeding people and patients whose future liver remnant is already sufficient or who are not receiving hypertrophy techniques are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the registry could help clinicians identify which liver-growth approaches are associated with better surgical outcomes and safer recovery.

How similar studies have performed: Techniques like portal vein embolization and ALPPS have been reported in prior studies with mixed but informative results, so this registry builds on existing clinical experience rather than testing a novel therapy.
