Correlation between CD4+CD29+T cells and metastasis and radiotherapy for patients with pulmonary ade- nocarcinoma / 实用医学杂志

ABSTRACT

Objective To observe the correlation between CD4+ CD29+ T cells and metastasis and radiotherapy for patients with pulmonary adenocarcinoma. Method Seventy-one patients with lung adenocarcinoma, 93 patients with lung adenocarcinoma ,76 cases of chronic obstructive pulmonary disease (COPD),63 cases of healthy volunteers were enrolled. Frequencies of blood CD4+ CD29+ T cells and their intracellular necrosis factor alpha(TNF-α)and interleukin 1(IL-1)were compared. Compare TNF-α,IL-1,integrin beta 1 and vascular endothelial growth factor(VEGF)levels in the patients with transferred pulmonary adenocarcinoma or with non-transferred pulmonary adenocarcinoma and their changes with the treatment of radiotherapy. Results the patients with lung adenocarcinoma and non lung adenocarcinoma were significantly higher than that of COPD and health group,and patients with lung adenocarcinoma is significantly higher than patients with non lung adenocarcinoma (P<0.05);Integrin beta 1,VEGF and CD4+CD29+T cells,TNF-αand IL-1 level in patients with lung adeno-carcinoma metastasis were significantly higher than non-transferred group(P < 0.05);After radiotherapy,CD4+CD29+T cells,TNF-αand IL-1 in patients with lung adenocarcinoma were significantly lower than before(P<0.05);CD4+ CD29+ T cells,TNF alpha and IL-1 with integrin beta 1 and VEGF had significantly positive correlations. Conclusion CD4+CD29+T cells and cytokines increase significantly in the blood of patients with lung adenocarci-noma,and are related to the prognosis of metastasis and radiation therapy,which has important clinical significance.
