Objective: We aimed to study the influence of neoadjuvant chemotherapy on immunity function in elderly patients with the stages of II and III esophageal cancer. Methods: Thirty-seven elderly patients (age ranged from 60 to 75 years) with the stages of II and III esophageal cancer underwent 2 cycles chemotherapy preoperatively with single-drug regimen (docetaxel, 35 mg/m2 once a week, on days 1, 8 and 15, at interval of 2 weeks for one cycle). Surgery were performed three weeks later. Blood samples were drawn separately on the day of admission, 1 day before operation, 7 day and 1 month after operation, and we conducted the Flow Cytometry to detect the levels of CD3+, CD4+, CD8+,CD4+/CD8+ and NK cells. Results: There were no significant differences in the levels of CD3+, CD4+, CD8+, CD4+/CD8+ and NK cells between before and after chemotherapy (P > 0.05). On day 7 after operation, the levels of CD3+, CD4+, CD4+/CD8+ and NK cells were degraded and CD8+ increased significantly (P < 0.05). One month after operation, the levels of CD3, CD4+, CD4+/CD8 and NK cells were higher than normal, and CD8 was depressed significantly (P < 0.05). Conclusion: Neoadjuvant chemotherapy has no significant impact on cellular immune function in elderly patients with the stages of II and III esophageal cancer, it is an effective and safe treatment.

No significant differences in the levels of CD3 +, CD4 +, CD8 +, CD4 + / CD8 + and NK cells were before and after chemotherapy (P> 0.05). On day 7 after operation, the levels of CD3 +, CD4 +, CD4 + / CD8 + and NK cells were degraded and CD8 + increased significantly (P <0.05) Ne month after operation, the levels of CD3, CD4 +, CD4 + / CD8 and NK cells were higher than normal, and CD8 was depressed significantly (P <0.05).
