Correlations of AKIP1, CXCL1 and CXCL2 expressions with clinicopathological features and survival profiles in cervical cancer patients
Abstract
Background: This study aimed to evaluate the correlation of A-kinase-interacting protein 1 (AKIP1) with C-X-C motif chemokine ligand (CXCL) 1 and CXCL2, and their associations with clinical characteristics and prognosis in cervical cancer patients.
Methods: One hundred and fifty early-stage cervical cancer patients treated with surgical resection were reviewed and tumor tissue samples were obtained. Expression of AKIP1, CXCL1 and CXCL2 was detected by immunohistochemistry (IHC). Data of tumor features were retrieved, and disease-free survival (DFS) as well as overall survival (OS) were calculated.
Results: AKIP1 expression was positively correlated with CXCL1 and CXCL2 expression in cervical cancer tissue (both P<0.001). AKIP1 expression was positively correlated with tumor size (P=0.040), lymph node (LYN) metastasis (P=0.034) and International Federation of Gynecology and Obstetrics (FIGO) stage (P=0.021); CXCL1 expression was positively associated with tumor size (P=0.048); and CXCL2 expression was positively correlated with LYN metastasis (P=0.026). As for DFS and OS, AKIP1 high expression was correlated with worse DFS (P=0.016) and OS (P=0.007), CXCL1 high expression was associated with poor DFS (P=0.029) but not OS (P=0.118). No correlation of CXCL2 expression with DFS (P=0.141) or OS (P=0.125) was found.
Conclusions: AKIP1 positively correlates with CXCL1/CXCL2, and associates with advanced tumor features as well as unfavorable survival profiles in cervical cancer patients.
