Abstract:Objective To investigate the changes of lymphocyte subsets(CD3+,CD4+,CD8+,CD4+/CD8+)in peripheral blood before and after chemotherapy in patients with diffuse large B-cell lymphoma(DLBCL)and their clinical significance.Methods A total of 56 patients with DLBCL who visited Provincial Hospital affiliated to Anhui Medical University for the first time from May 2018 to May 2020 were retrospectively selected as the research subjects,and all patients were pathologically confirmed.According to the ratio of CD4+/CD8+in peripheral blood before chemotherapy,the patients were divided into two groups as the elevated/normal group(group A)39 cases and the reduced group(group B)17 cases.All patients received R-CHOP regimen after admission,After four cycles of chemotherapy,the patients were divided into elevated/normal group(group C)31 cases and decreased group(group D)25 cases according to the ratio of CD4+/CD8+in peripheral blood,and analyzed the changes of immune function and its relationship with prognosis in patients with different clinical characteristics.Results After treatment,the levels of CD3+and CD8+in two groups were higher than before treatment,while the level of CD4+/CD8+was lower than before treatment,the differences were statistically significant(P<0.05).After treatment,the patients in group A had less progression than group B,and the progression-free survival time in group A was longer than that in group B,the differences were statistically significant(P<0.05).The incidence of thrombocytopenia in group D was higher than that in group C,and the difference was statistically significant(P<0.05).Conclusion The immunestatus of patients with diffuse large B-cell lymphoma have changed,and the detection of peripheral blood lymphocyte subsets was of high value for the evaluation and diagnosis.Peripheral blood immune cell monitoring of patients could timely determine the immune status of patients in order to better guide the use of chemotherapy drugs.
