Objective To observe the changes of immune parameters of patients with different cervical cancer treated with cytokine-induced killer(CIK)cells after radical hysterectomy in order to provide data for clinical evaluation.Methods 50 ml peripheral blood was collected the day before CIK cell therapy and after a course of treatment from ninety-eight radical hysterectomy patients(56 cases of squamous carcinoma, 25 cases of adenocarcinoma,and 17 cases of adenosquamous carcinoma) treated in the Department of Gynaecology and Obstetrics and Department of Oncology between January 2014 and September 2016.According to the process of CIK cell therapy, the serum was separated, and the proportion of CD3⁺、CD4⁺、CD8⁺、CD4/CD8、and NK cells in the serum was analyzed using flow cytometry (FCM).Results 1.The proportion of CD3⁺ and NK cells in the 98 patients was increased after CIK cell therapy.The proportion of CD4⁺ and CD4/CD8 rose only in patients of squamous carcinoma and adenocarcinoma.The proportion of CD8⁺ did not change significantly.2.The result of CD3⁺ and NK cells suggested that after treatment the immune parameters in patients of adenocarcinoma were significantly higher than those in patients of squamous carcinoma and adenosquamous carcinoma (P<0.05).After treatment, CD3⁺ and NK cells increased from 60.71±5.84 to 67.27±3.04 and from 8.92±3.64 to 12.93±6.25 respectively in patients of squamous carcinoma, from 59.91±2.49 to 68.32±8.24 and from 9.04±5.31 to 17.87±6.46 respectively in patients of adenocarcinoma,and finally from 59.01±5.90 to 65.23±7.07 and from 59±3.97 to 15.07±2.71 respectively in patients of adenosquamous carcinoma.Conclusions CIK cell therapy can markedly enhance the immunity of patients after radical hysterectomy. It’s of great significance for improving the quality of survival.
