Abstract
Background: Hypoxia inducible factor-1α(HIF-1α) is a transcription factor for various target genes that are involved in adapting cells to hypoxia. It promotes cell proliferation and survival via modulation of such cell cycle regulators such as cyclin A1 and cyclin B1 in response to hypoxia. This is associated with local failure of radiotherapy, which renders a poor prognosis for cervical carcinoma. Methods: Using the tissue histologic sections and a tissue microarray of the archived biopsy and surgical specimens of uterine cervical carcinoma from 57 patients who were treated with radiation therapy alone, we performed immunohistochemical staining for HIF-1αand cyclin A1 and B1 to evaluate the correlations between the expressions of these proteins in tumors and the clinicopathologic parameters associated with the prognosis. Results: The large tumor cell nests and invasive front margins of the tumors showed comparatively intense immunoreactivity of HIF-1α. There was no significant correlation between the HIF-1α, cyclin A1 and cyclin B1 expressions and the clinicopathologic factors. Conclusions: The HIF-1αexpression showed marked intra-tumoral heterogeneity. The HIF-1αexpression is neither a powerful predictor of resistance to radiotherapy nor is it a poor prognostic marker in cervical carcinoma patients who are treated with radiotherapy. The expressions of cyclin A1 and cyclin B1 are neither independently associated with the response of radiation therapy nor are they associated with the prognostic parameters of uterine cervical carcinoma
