Résumé
Objective:To analyze the prognostic factors affecting salvage liver transplantation (SLT).Methods:The clinical data of 97 patients undergoing liver transplantation in the Ningbo Medical Centre Lihuili Hospital from January 2012 to May 2022 were retrospectively analyzed, including 84 males and 13 females, aged (53.6±7.4) years. Among them, 33 patients underwent primary liver transplantation (PLT) and 64 underwent SLT. SLT patients were subdivided into the groups within the Milan criteria (SLT-A, n=35) and beyond the Milan criteria (SLT-B, n=29), according to whether the Milan criteria were met at first hepatectomy. Clinicopathological and prognostic data were subsequently analyzed. Results:The tumor number ( χ2=16.03, P<0.001), microvascular invasion (MVI) ( χ2=10.97, P=0.004), recurrence rate ( χ2=9.31, P=0.010), recurrence-free survival (RFS, F=14.05, P=0.001) and overall survival (OS, F=17.27, P<0.001) were significantly different among the three groups. RFS ( P=0.047) and OS ( P=0.012) in PLT group were better than those in SLT-B group. RFS ( P=0.007) and OS ( P=0.024) in SLT-A group were also better than those in SLT-B group. The multivariate analysis indicated that beyond the Milan criteria at first hepatectomy was an independent risk factor for RFS ( HR=4.378, 95% CI: 1.393-13.756, P=0.011) and OS ( HR=5.391, 95% CI: 1.428-20.352, P=0.013) in patients undergoing SLT, and MVI positive ( HR=4.042, 95% CI: 1.137-14.368, P=0.031) was an independent risk factor for RFS in patients undergoing SLT. Conclusion:Patients beyond the Milan criteria at first hepatectomy and MVI positive showed a poorer prognosis after SLT. Whether the Milan criteria should be the gold standard for SLT as well as for PLT needs further study.
Résumé
Objective:To investigate the risk factors for postoperative early recurrence of patients with single large hepatocellular carcinoma (HCC) (tumor diameter≥5cm).Methods:Clinical data of 135 single large HCC patients who underwent radical resection from Jan 2015 to Sep 2020 in Ningbo Medical Centre Lihuili Hospital were analyzed.Results:Seventy-five HCC patients suffered recurrence,among those 42 patients had early recurrence(within 12 months). Multivariate analysis showed that alpha-fetoprotein (AFP)≥400 ng/ml ( OR=3.510,95% CI: 1.528-8.064; P=0.003) and tumor microvascular invasion (MVI) ( OR=2.769,95% CI: 1.143-6.706; P=0.024) were independent risk factors for early recurrence of single large hepatocellular carcinoma. Survival analysis showed that early recurrence risk factors significantly reduced recurrence free survival (RFS)(AFP≥400 ng/ml, χ 2=23.038, P<0.001; MVI positive , χ 2=10.554, P=0.001) and overall survival (OS) (AFP≥400 ng/ml, χ 2=14.336, P<0.001; MVI positive, χ 2=10.481, P=0.001) in single large hepatocellular carcinoma patients. Conclusion:AFP≥400 ng/ml and MVI positive are independent risk factors for postoperative early recurrence in single large hepatocellular carcinoma patients.
