Co-expression of XIAP and CIAP1 Play Synergistic Effect on Patient’s Prognosis in Head and Neck Cancer

Abstract

To explore the influence of chemotherapy on prognosis of Head and Neck Squamous Cell Carcinoma (HNSCC) and the relationship between XIAP and CIAP1 co-expression and the prognosis in HNSCC. 129 patients were recruited in our study, they were divided into two groups, neoadjuvant group (n = 60) and non-neoadjuvant group (n = 69). Expression level of XIAP and CIAP1 were examed in neoadjuvant group, and was correlated with clinical outcomes of the patients. The unselected patients were not benefit from neoadjuvant chemotherapy. Moreover, the patients whose tumors co-express high level of XIAP and CIAP1 presented poorer overall and disease-free survival rates than those whose tumors co-express low level of XIAP and CIAP1 (overall survival P < 0.001, disease-free survival P < 0.001). Our results validate that individual chemotherapy is important for HNSCC, and co-expression of XIAP and CIAP1 prompted a worse prognosis.
