IL6 and cervical cancer: The levels of IL-6 and IL-10 were positively correlated at the pre- and postoperation stages, suggesting that these two cytokines may play a key role in immune regulation in cervical cancer; (iii) at the relapse phase, the levels of IL-6, IL-8, IL-12p70, IL-17, and IFN-γ were the positively correlated, suggesting that these cytokines may associated with 5-year relapse rates and/or the metastasis of cervical cancer; and (iv) in the initial diagnosis cohort, high levels of IL-17 were associated with shorter overall survival times among patients with positive nodal status.
