Abstract

IL-6 has been found to be associated with poor response to chemoradiotherapy and poor overall prognosis of patients with cervical cancer. However, little is known about the clinicopathological significance of IL-6 receptor (IL-6R) expression in the setting of cervical cancer. To investigate the clinicopathological meaning of IL-6R in cervical cancer, expression of IL-6R was detected using immunohistochemistry in cervical cancer tissue microarray composed of 98 cases of cervical cancer and paired normal controls. As further confirmation of expression trend, western-blotting was conducted in another independent 36 pairs of cervical cancer and matched normal controls. Subsequently, the statistical correlation between IL-6R expression and clinicopathological variables was analyzed, including demographic, TNM stage, clinical grading and overall prognosis. IL-6R expression was shown to be remarkably associated with lymph node metastasis, recurrence and overall prognosis. Moreover, only IL-6R expression was observed to be an independent prognostic factor among these variables that could potentially influence the overall prognosis of patients with cervical cancer. In conclusion, IL-6R was shown to be an independent prognostic factor for patients with cervical cancer.
