Abstract: Objective To explore the relationship between the international prognosis indexes(IPI) and the Th17 cells expression in DLBCL patients. Methods DLBCL patients (n=45) were divided into 4 groups according to IPI score, peripheral blood were taken from each person in DLBCL groups and normal group. We used ELISA to test IL-17 and flow cytometry (FCM) to examine the Th17 positive cells. We compared the value of each group, and analyzed the relativity of IPI and Th17 cells' expression. Results Th17 cells' expression level in middle-high risk group and high risk group were higher than that in normal group and other IPI groups; Th17 cells' expression level in DLBCL groups were all lower than that in normal group; Th17 cells decreased while IPI score increased; Age, clinical stage and general body state have the relativity with DLBCL patients' Th17 cells expression level. Conclusion Th17 cells in DLBCL patients has the relativity with prognosis index. In our clinical diagnosis and treatment, we need to pay more attention to those patients who are over 60 years old, or whose clinical stage is above Ⅲ phase, or who need to stay on bed for a long time and need other peoples' help .
