Abstract:
Objective To investigate peripheral blood T lymphocyte subsets and NK cells changes in the diffuse large B cell lymphoma (DLBCL) patients before and after chemotherapy,and analyse the relationship between the results and treatment.Methods Collect the 47 patients venous blood of the effective treatment DLBCL by pathology.T lymphocyte subsets and NK cells were determined by flow cytometric.Analyse the results statistically significant difference before treatment,the second chemotherapy cycle and the fourth chenmotherapy cycle compared with 50 healthy control persons.Results The levels of CD3+,CD4+,CD4+/CD8+ NK cells in DLBCL patients before chemotherapy [(70.04±8.87)％,(42.79±6.06)％,(1.68±0.59)％,(14.40±6.02)％]were lower than healthy controls [(63.89±6.67)％,(32.72±5.77)％,(0.85±0.25)％,(9.95±5.24)％](P ＜ 0.05),and the level of CD8+ cells is higher than the healthy controls [(27.21 ±6.54)％ vs.(39.92±7.11)％](P ＜ 0.05).The levels of CD3+,CD4+,CD4+/CD8+ cells had significant difference between the second and the fourth chemotherapy cycle in DLBCL patients (P ＜ 0.05).The levels of CD3+,CD4+,CD8+,CD4+/CD8+,NK cells had significant difference between the fourth chemotherapy cycle DLBCL patients and the DLBCL patients before chemotherapy (P ＜ 0.05).Conclusion The DLBCL patients exist immunosuppression before chemotherapy.Peripheral T lymphocyte subsets and NK cells can be used as good reflect of the cellular immune function in DLBCL patients.Clinical parameters can be used for the immune function monitoring and providing guidance for the treatment options.
