RESUMO
Objective To observe the roh of cytoimmunologic factors,careinoembryonic antigen (CEA),serum ferritin(SF)and prognostic factors in patients with Iung adenous cancer.Methods Eightyone patients with lung adenous cancer were analyzed retrospectively.The clinical features as well as the alternation of T-lymphocyte subsets and its relationship with CEA.SF,disease stage and metastasis of lymph node were studied.Results(1)The percentage of CD4+ T cell decreased and that of CD8+T cell increased,the ratio of CD4+/CD8+ went down accompanied by the increase of disease stage.CEA and SF increased as the dmease stage increased.(2)Thedecrease of percentage of CD4+ T cell and the ratio of CD4+/CD8+ was obvious in patients with metastasis of lymph nodes[LN(+)](p＜0.01).The increase of percentage of CD8+Tcell and CEA,SF level was obvious in LN(+)(P＜0.01 or＜0.05).(3)The decrease of percentage of CD4+T cell and the ratio of CD4+/CD4+ was obvious in CEA (+)(P＜0.01).The increase of percentage of CD8+ T cell and SF level was obvious in CEA (+)(P＜0.01).(4)The decrease of percentage of CD4+ T cell and the ratio of CD4+/CD8+ was obvious in SF(+)(P＜0.01).The increase of percentage of CD3+ CD8+ T cell and the CEA level was obvious in SF (+)(P＜0.05 or＜0.01).Conclusion Disorder of cytoimmunologic situation exists in patients with lung adenous cancer,and it is closely correlatod with the CEA,SF level disease stage and metastasis of lymph node.
