Correlation analysis of peripheral blood T cell subgroups, immunoglobulin and prognosis of early hepatocellular carcinoma after hepatectomy.

To investigate the prediction value of preoperative changes in the immunological function for the prognosis of hepatocellular carcinoma (HCC) after hepatectomy, 158 cases of HCC patients who received liver resection in our hospital from 2009 to 2010 were enrolled in this study. Immune indices [CD3(+), CD4(+), CD8(+), CD19(+) and natural killer (NK), IgA, IgM, IgG], AFP level were calculated. The differences between preoperation and postoperation group, exclude were not both statistically significant (both P > 0.05), whereas IgA group was not (P < 0.05),The follow-up data showed that the 3-year recurrence rates of high level group on HBsAg, CD3, CD4, CD8, CD19 and IgGwerelarger than that of low level group,while the 3-year recurrence rates of high level group on AFP, NK, IgA and IgM smaller than that of low level group, and we found that CD3(+), CD4(+), CD8(+) and NK(+), CD19(+), HBsAg, IgA and IgG above were statistically different (P < 0.05), AFP and IgM were no difference with prognosis of HCC (P > 0.05).The markers level were not both statistically significant with age, gender, grade, tumor size (P > 0.05). Multiple logistic regression analysis indicated that CD4(+), CD8(+) and NK(+) were closely correlated with HCC postoperative survival rate (P < 0.05) (Y = 1.262×CD4(+)+1.448×CD8(+)-0.646×NK(+)). Construction of Cox's proportional hazards regression model showed IgA and IgG were correlated with HCC postoperative survival rate at a trend (P = 0.079) (Y = 127.9×IgG-28.7×IgM). Preoperative Immune indices (CD4(+), CD8(+), NK(+), IgA, IgG) were closely correlated with HCC survival rate and these were considerable predictive value for the malignantfeature and prognosis of HCC.
