Background and Objectives Various tumor markers have been studied in an attempt to evaluate and decide the optimal treatment of the patients with head and neek squamous cell carcinoma (HNSCC). A nuclear antigen Ki-67 is a proliferative marker of tumor cells in all phases of cell cycle except G0. c-met gene, the tyrosine kinase receptor for hepatocyte growth tactor, may play various roles in malignant transformation. The authors evaluated the prognostic significance of Ki-67 and c-Met in surgical specimens of HNSCC to determine the relationship with the various clinicopathological characteristics. Materials and Methods Formatin-fixed paraffin-embedded surgical specimens were obtained from 54 patients with HNSCC. Ki-67 and c-Met expressions were analyzed by immunohistochemical staning and were compared with the clinicopathological characteristics such as, pathologic differentiation, tumor stage, clinical stage and lymph node metastasis. Results Ki-67 and c-Met over-expression was detected in 66.7% and 90.7% in HNSCC. There was positive correlation of increased expression of Ki-67 with tumor stage. and clinical stage, increased expression of e-Met with tumor stage, clinical stage, and nodal status. The expression of c-Met had a significant positive relationship with Ki-67 index (p<0.05). Conclusion Therefore, Ki-67 and c-Met are useful markers of tumor progression, aggressiveness and prognosis in HNSCC.
