Moderating Effects and Maintenance of Lung Cancer Cellular Immune Functions by CIK Cell Therapy

Aims: To study the CIK cell treatment effects on regulation of cellular immune function disorders in patientswith lung cancer, and to analyze the time characteristics.
Methods: Cellular immune function was assessedby FCM, and patients with functional disorders were randomly divided into two groups, one given CIK celltherapy within 18 months (5 courses) and the other the controls, which were followed up for 1 year withcellular immune functions tested once a month.
Results: There were 5 types of cellular immunity, 4 of which aredisorders; after CIK treatment, the improvement rate of the 4 groups were 79.1%, 70.8%, 76.0% and 70.0%,intergroup differences not being statistically significant (P=0.675), all significantly higher than in the controlgroup (P=0.000). The median maintenance times for the 4 groups were 10.4 months (9.76-11.04), 8.4 months(7.86-8.94), 9.8 months (9.20-10.4) and 7.9 months (6.25-9.55), respectively.
Conclusions: CIK cells were ableto improve the immune functions of patients with lung cancer, the rate of improvement and maintenance timebeing related to the immune function before the treatment and CIK-cell-therapy courses.
