Expression and clinical significance of cervical cancer related cytokines in Xinjiang Uyghur and Han nationalities / 重庆医学

ABSTRACT

Objective To compare the differences of cytokines IFN‐γ,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 ,IL‐13 and IL‐17 expression lev‐els mainly secreted by peripheral blood Th1 ,Th2 and Th17 cells and to investigate the correlation between the cytokines in the Han and Uyghur cervical cancer patients with the clinical stage and tumor differentiation degree .Methods The blood samples in 66 ca‐ses of pathologically diagnosed cervical cancer (Han in 22 cases ,Uyghur in 44 cases) before treatment in our hospital were collect‐ed .The concentrations of IFN‐γ,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 ,IL‐13 and IL‐17 were measured by using Luminex assay ,then the differ‐ences of cytokines were compared between Han and Uyghur patients;according to the clinical stage and tumor differentiation de‐gree ,the grouping was performed ,then the differences of cytokines in different subgroups were compared between Han and Uyghur cervical cancer patients .Results The levels of IFN‐γ,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 ,IL‐13 and IL‐17 in the Uyghur cervical cancer group were higher than those in the Han cervical cancer group(P<0 .05);the levels of IL‐2 ,IL‐4 and IL‐10 secreted by Th cells in the stage Ⅰ - Ⅱ Uyghur cervical cancer group were higher than those in the stage Ⅰ - Ⅱ Han cervical cancer group(P<0 .05);the levels of IFN‐γ ,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 ,IL‐13 and IL‐17secreted by Th cells in the stage Ⅲ - Ⅳ Uyghur cervical cancer group were higher than those in the stage Ⅲ - Ⅳ Han cervical cancer group(P<0 .05);the levels of IFN‐γ,IL‐2 ,IL‐4 ,IL‐6 ,IL‐10 ,IL‐13 and IL‐17 secreted by Th cells in middle to high differentiation Uyghur cervical cancer group were higher than those in middle to high differentiation Han cervical cancer group(P<0 .05) .Conclusion In the HPV16‐positive cervical cancer patients ,the concentrations of cytokines secreted by Th cells are different between Uyghur group and Han group ,these differences are more significant in the stage Ⅲ - Ⅳ cervical cancer and in middle to high differentiated cervical cancer .
