Abstract:
ObjectiveTo investigate changes of the cellular immune function in the elderly patients with nonsmall-cell lung cancer (NSCLC) after chemotherapy.Methods T-lymphocyte subsets and natural killer cell were detected in 29 elderly patients with NSCLC,20 adults with NSCLC and 22 healthy elderly,and their levels were compared between pre-chemotherapy and at the end of 2 cycles of chemotherapy in the elderly patients with NSCLC.ResultsThe levels of CD3,CD4,CD8,CD4/CD8andNK cell were (58.9±15.8),(32.3±12.7),(22.0±9.8),(1.3±0.7),(21.6± 7.7),respectively in the elderly patients with NSCLC,(65.9 ± 7.2),(38.5 ± 7.6),(23.1 ± 9.2),(1.5±0.7),(16.8±6.2),respectively in adults with NSCLC and (67.3±9.0),(39.0±7.8),(23.9±9.3),(2.0±1.6),(22.5±5.8),respectively in healthy elderly.The levels of CD3 and CD4 were decreased (t=2.109,2.159,P＜0.05) and NK cell was increased (t=2.273,P＜0.05) while CD8 and CD4/CD8 had no difference(t = 0.406,0.736,P＞ 0.05 ) in the elderly patients with NSCLC as compared with adults with NSCLC.The levels of CD3,CD4,and CD4/CD8 were lower (t = 2.234,2.200,2.016,all P＜ 0.05) in elderly patients with NSCLC than in healthy elderly,with no significant change in the levels of CD8 and NK cell(t= 0.700,0.474,P＞0.05) between the two groups.The levels of CD3 (51.6 ±10.3)was reduced(t=2.067,P＜0.05) and CD4 (31.7 ± 11.7),CD8(21.6 ± 6.5),CD4/CD8 (1.3 ± 0.7),NK cell (26.0 ±12.7)had no remarkable difference (t =0.186,0.180,0.289,1.570,all P＞ 0.05)after chemotherapy in elderly patients with NSCLC.ConclusionsThe cellular immune function in the elderly patients with NSCLC is lower than in adults with NSCLC and healthy elderly,and further decreases after chemotherapy.
