ABSTRACT

Background: IL-1α and IL-6 are associated with the prognosis of a wide range of cancers, but their value in cervical cancer remains controversial. The aim of this study was to investigate the expression of IL-1α and IL-6 in cervical cancer and their significance in clinical prognosis.

Material/methods: The expression of IL-1α and IL-6 in 105 formalin-fixed, paraffin-embedded cervical cancer tissues and adjacent non-tumor tissues was examined by immunohistochemistry. The results were semi-quantitatively scored and analyzed by chi-square test. Patient overall survival (OS) data was collected by follow-up and analyzed by Kaplan-Meier analysis.

Results: The expression level of both IL-1α and IL-6 in cervical cancer tissue was higher than in adjacent non-tumor tissues (p<0.05). IL-1α expression was shown to be correlated with tumor size, FIGO histology grade, lymph node metastasis, stromal invasion, and tumor differentiation (p<0.05). IL-6 expression was shown to be correlated with tumor size, FIGO histology grade, and tumor differentiation (p<0.05). Patients with positive expression of IL-1α or IL-6 tended to have much shorter survival times than patients with negative expression. In addition, a multivariate Cox regression analysis demonstrated that IL-1α expression and lymph node metastasis were independent predictors of OS in cervical cancer patients.

Conclusions: The expression of IL-1α was significantly associated with tumor size, FIGO histology grade, lymph node metastasis, stromal invasion, and tumor differentiation. The expression of IL-6 was significantly associated with tumor size, FIGO histology grade, and tumor differentiation. Positive IL-1α and IL-6 expression was significantly correlated with poor prognosis. They may be considered valuable biomarkers for prognosis and potential therapeutic targets for cervical cancer.

Mentions: Typical immunohistochemistry images of IL-1α and IL-6 in cervical cancer tissues and paired adjacent non-tumor tissues are shown in Figures 1 and 2. The positive percentages of IL-1α expression in cervical cancer and adjacent non-tumor tissues were 63.8% (67/105) and 8.6% (9/105), respectively. The positive percentages of IL-6 expression in cervical cancer and adjacent non-tumor tissues were 60.0% (63/105) and 10.5% (11/105), respectively. The chi-square test was used to confirm that the difference in the expression level of IL-1α and IL-6 between cervical cancer tissues and paired adjacent non-tumor tissues was statistically significant (p<0.05).
