Summary
Higher serum zinc levels before liver surgery correlate with better liver regeneration. This finding is crucial for patients undergoing hepatectomy, as adequate zinc supports remnant liver growth after tumor removal.
Area of Science:
- Hepatology
- Surgical Oncology
- Nutritional Science
Background:
- Liver regeneration is critical for successful hepatectomy, especially for extensive liver tumor burdens.
- Zinc is essential for rapid cellular proliferation required during liver regeneration.
Purpose of the Study:
- To investigate the influence of serum zinc concentrations on remnant liver regeneration and short-term outcomes after hepatectomy in liver cancer patients.
Main Methods:
- Serum zinc levels were measured in 77 patients pre-hepatectomy.
- Patients were categorized into high (≥75 µg/dL) and low (<75 µg/dL) zinc groups.
- Remnant liver volume and hypertrophy were assessed post-hepatectomy.
Main Results:
- No significant differences in mortality, morbidity, or hospital stay were observed between high and low zinc groups.
- Patients with higher pre-hepatectomy serum zinc exhibited significantly greater future liver remnant hypertrophy (p=0.024).
- This association remained significant in a subgroup undergoing extended hepatectomy (p=0.037).
Conclusions:
- Pre-operative serum zinc concentration is a key factor influencing liver remnant regeneration.
- Higher zinc levels are associated with enhanced liver hypertrophy post-hepatectomy.
