RESUMEN
Objective To analyze the effect of diabetes mellitus (DM) on the prognosis of patients with unresectable hepatocellular carcinoma (HCC) after receiving transcatheter arterial chemoembolization (TACE).Methods A total of 858 HCC patients,who were admitted to the Affiliated Xinhua Hospital,School of Medicine,Shanghai Jiaotong University,China,during the period from January 2010 to June 2015 to receive TACE,were selected.Among the 858 HCC patients,175 patients suffered from coexisting DM (DM group) and 683 patients had no DM (non-DM group).The differences in general clinical data and overall survival between the two groups were analyzed.Kaplan-Meier method was used to calculate the survival rate,the difference between the two groups was evaluated by log-rank method,and Cox proportional hazards regression was adopted to analyze the prognostic factors of HCC patients after receiving TACE.Results There were no statistically significant differences in sex,age,serum albumin,total bilirubin,prothrombin time,alpha fetoprotein (AFP),Child-Pugh grade,tumor size and number,cirrhosis,number of TACE treatment times and BCLC staging between the two groups (P＞0.05);the fasting blood glucose (FPG)level in DM group was higher than that in non-DM group (P＜0.05).The 1-,3-and5-year survival rates of the DM group were 60.9％,27.5％ and 10.7％ respectively,which were 70.9％,36.0％ and 17.6％ respectively in the non-DM group;the Log-rank test showed that the difference between the two groups was statistically significant (P=0.008).Multivariate Cox proportional hazard regression analysis revealed that the largest tumor diameter ＞5 cm,multiple tumor lesions,AFP＞20 ng/ml,BCLC stage and coexisting DM were independent risk factors that affected the prognosis of HCC patients after receiving TACE.Conclusion The coexisting DM is an independent risk factor that may affect the prognosis of patients with inoperable HCC after receiving TACE.
