RESUMO
Background: Elevated preoperative γ-glutamyl transferase (GGT) levels or reduced serum albumin levels have been established as negative prognostic factors for patients with hepatocellular carcinoma (HCC) and various other tumors. Nonetheless, the prognostic significance of the GGT to serum albumin ratio (GAR) in liver transplantation (LT) therapy for HCC is still not well-defined. Methods: A retrospective analysis was conducted on the clinical data of 141 HCC patients who underwent LT at Shulan (Hangzhou) Hospital from June 2017 to November 2020. Using the receiver operating characteristic (ROC) curve, the optimal GAR cutoff value to predict outcomes following LT was assessed. Univariate and multivariate Cox proportional hazards regression analyses were used to identify independent risk factors associated with both overall survival (OS) and recurrence-free survival (RFS). Results: A GAR value of 2.04 was identified as the optimal cutoff for predicting both OS and RFS, with a sensitivity of 63.2% and a specificity of 74.8%. Among these patients, 80 (56.7%) and 90 (63.8%) met the Milan and the University of California San Francisco (UCSF) criteria, respectively. Univariate Cox regression analysis showed that microvascular invasion (MVI), maximum tumor size (>5 cm), total tumor size (>8 cm), liver cirrhosis, TNM stage (III), and GAR (≥2.04) were significantly associated with both postoperative OS and RFS in patients with HCC (all p < 0.05). Multivariate Cox regression analysis indicated that GAR (≥2.04) was independently linked with RFS and OS. Conclusion: Pre-transplant GAR ≥2.04 is an independent correlate of prognosis and survival outcomes after LT for HCC and can be used as a prognostic indicator for both mortality and tumor recurrence following LT.
RESUMO
Liver transplantation (LT) for acute-on-chronic liver failure (ACLF) accompanied by acute necrotizing pancreatitis is still unclear. We have a reported case of LT for ACLF associated with acute necrotizing pancreatitis. The postoperative multiorgan dysfunction and secondary infection were successfully managed under close supervision. The patient was a 47-year-old man with chronic hepatitis B virus infection presented with ACLF and acute necrotizing pancreatitis. After receiving LT from a deceased donor, the patient's liver functioning rapidly reverted to a normal level, and the acute pancreatitis was simultaneously stabilized. However, the patient later developed multiorgan dysfunction secondary to multidrug resistant bacteria infection, which was treated successfully with repeated percutaneous drainage, sensitive antibiotics, continuous renal replacement therapy, microbial balance, and best supportive care. LT can be considered for ACLF associated with acute necrotic pancreatitis without absolute contraindication. Moreover, we recommend a close observation of possible postoperative severe infection, and cautious multidisciplinary management was needed for the prevention of organ dysfunction.
