Outline of Final Research Achievements

Neutrophil lymphocyte ratio >4 had siniginicant impact on recurrent hepatocellular carcinoma after liver transplantation. Multivariate analyses showed that NLR >4, tumor size >5cm, the interval between last treatment and liver transplantation <3 months, were significantly associated with recurrence. In cases with NLR >4, peritumor and serum IL17 was significantly elevated, indicating that IL17 had significant impact on tumor progression. Moreover, the number of peritumor CD163 positive cells, indicating macrophage, was increased compared with those with NLR <4. Therefore, high NLR indicates that tumor progression, recurrenct heaptocellualr carcinoma after liver transplantation in this study, was positively influenced by peritumor environment especially tumor associated macrophage and IL17.
