Abstract:
Objective To study the relationship between preoperative serum a-fetoprotein (AFP) level and early recurrence of patients with hepatocellular carcinoma (HCC) after partial hepatectomy.Methods 267 patients with hepatocellular carcinoma who underwent partial hepatectomy in Xijing Hospital,the Fourth Military Medical University from January 2011 to November 2015 were retrospectively studied.The patients were divided into the AFP-negative group (AFP ≤20 μg/L) and the AFP-positive group (AFP > 20 μg/L) according to the preoperative serum AFP levels.The risk factors of early recurrence of HCC in patients after partial hepatectomy were studied by multivariate regression analysis.The recurrence-free survival rates during 24 months after surgery between the AFP-negative group and the AFP-positive group were compared.Results In 267 patients,97 patients had low or negative AFP levels (AFP≤20 μg/L) and 170 patients had high or positive AFP levels (AFP > 20 μg/L).Patients in the AFP-positive group had significantly more well differentiated HCC on tumor histology when compared with patients in the AFP-negative group (x2 =17.050,P < 0.05).The proportion of patients with liver cirrhosis in the AFP-positive group was significantly higher than that of the AFP-negative group (x2 =4.374,P < 0.05).On the other hand,the numbers of patients with adjacent tissue invasion (x2 =4.374,P < 0.05) and early HCC recurrence (x2 =7.595,P < 0.05) in the AFP-positive group were significantly less than those of the AFP-negative group.Survival analysis showed that the recurrence-free survival rates in the AFP-positive and negative groups were 35.3%,52.6%,respectively.The results on univariate analysis showed that portal vein tumor thrombus,HBsAg positivity,tumor number,tumor diameter,tumor tissue differentiation,preoperative serum AFP level and adjacent tissue invasion were significantly associated with early recurrence of liver cancer (P < 0.05).Cox multivariate regression analysis revealed that serum AFP positivity (HR =1.605,P < 0.05),portal vein tumor thrombosis (HR =3.936,P < 0.05),HBsAg positivity (HR =1.621,P <0.05),tumor diameter (HR =1.977,P < 0.05) and tumor number (HR =1.991,P < 0.05) were significantly correlated with early recurrence of liver cancer after partial hepatectomy.Conclusion The preoperative serum AFP level had an important predictive value for early recurrence of primary hepatocellular carcinoma in patients after partial hepatectomy.
