ABSTRACT

BACKGROUND: Metastasis-associated in colon cancer-1 (MACC1, was firstly found in colon cancer and associated metastasis and prognosis in various cancers), anterior gradient 2 (AGR2, was considered as a valuable prognostic factor for some cancers), and Kangai 1 (KAI1, was a tumor metastasis suppressor gene) are all related to metastasis and prognosis of many cancers. However, the associations of MACC1, AGR2, and KAI1 in head and neck squamous cell carcinoma (HNSCC) are still unclear. In this study, we analyzed associations among MACC1, AGR2, and KAI1 in HNSCC, and their respective associations with clinicopathological parameters and overall survival (OS) in HNSCC. METHODS: Positive expression of MACC1, AGR2, and KAI1 in 106 whole HNSCC tissue samples was detected by immunohistochemical staining. Patient's clinical data and demographics were both collected. RESULTS: Positive rates of MACC1 and AGR2 were significantly higher, and positive rate of KAI1 was significantly lower, in HNSCC and than those in control tissues. Positive rates of MACC1 and AGR2 were positively correlated with grades of tumor, TNM stages, and lymph node metastasis (LNM) stages, and negatively with patients OS; positive rate of KAI1 was negatively associated with grades of tumor, TNM stages, and LNM stages, and the positive expression of KAI1 subgroup had significantly longer OS than did the negative KAI1 subgroup. In multivariate analysis, positive expression MACC1, AGR2, and KAI1, and tumor stages, as well as LNM stages were potential to be independent prognostic factors for OS in patients with HNSCC. CONCLUSIONS: MACC1, AGR2, and KAI1 may represent potential metastatic and prognostic biomarkers, as well as promising therapeutic targets for HNSCC.

ABSTRACT

OBJECTIVE: To study the function of lymphangiogenesis and the expression of Cathepsin D (Cath-D) in laryngeal carcinoma metabasis and clinical pathology character. METHOD: The expression of Cath-D were detected in 76 laryngeal carcinoma with immunohistochemistry (SP method). Podoplanin was used as the marker of lympgatic vessel endotheliocytes to label lympgatic vessel in 76 laryngeal carcinoma,lymphatic microvessel density were measured,and the paraneoplastic tissues was used as control group. RESULT: The positive rate of Cath-D in paraneoplastic tissue, laryngeal carcinoma and in pathology classification, in clinical stage, in cervicale lymphonode metastasis negative and positive group were significantly different. However, there had no difference between the positive rate of Cath-D in the age specific and clinical classification. c) The lymphatic microvessel density in paraneoplastic tissue, laryngeal carcinoma and clinical stage, in glottic carcinoma and supraglottic carcinoma, in cervical lymphonode metastasis negative and positive group were significantly different; but there had no difference in age-specific and pathology classification. CONCLUSION: (1) The high expression of lymphatic microvessel density and the increasing expression of Cath-D could promote cervical lymphonode metastasis in aryngeal carcinoma. (2) There had a correlation between the high expression of lymphangiogenesis and Cath-D in laryngeal carcinoma, and had cooperation in aryngeal carcinoma lymphonode metastasis.
