Abstract/OtherAbstract:
AIMS: We studied the relationships between the growth, metastasis and angiogenesis of laryngeal carcinoma and extracellular matrix protein-1 (ECM1) and hyaluronan (HA). METHODS: Thirty-three cases of benign and malignant laryngeal tumors were included. Using immunohistochemical staining, we examined the expression of ECM1 and HA in tumors and metastatic lymph nodes and correlated it with counts of microvessel density. RESULTS: The expression of ECM1 (p = 0.004) and HA (p = 0.036) was significantly different between benign and malignant tumors. The expression of ECM1 was strongly associated with microvessel density (Spearman's rho = 0.513, p = 0.017), with the strongest expression present within caner nests. With respect to HA, expression was significantly associated with more advanced clinical TNM stage (Spearman's rho = 0.521, p = 0.015). The link was stronger in cases where metastasis or recurrence occurred than in those without complication (p = 0.014). No significant relationship was found between ECM1 and HA expression among malignant samples (Spearman's rho = 0.383, p = 0.087). CONCLUSIONS: ECM1 has a high association with the growth, metastasis and angiogenesis of laryngeal carcinoma. An increased level of HA expression was related to the process of laryngeal carcinogenesis. Specifically, carcinoma cells with high levels of HA secretion had a higher potential for metastasis. No significant relative expression of ECM1 and HA was found.
