OBJECTIVE@#To study the expressions of matrix metalloproteinase-2 (MMP-2) and E-cadherin in laryngeal carcinoma and their relationship with cervical lymph node metastasis.@*METHOD@#The expression of MMP-2 and E-cadherin in 10 cases of normal laryngeal mucosa and 48 cases of supraglottic carcinoma were detected by immunohistochemistry.@*RESULT@#The expression of MMP-2 in supraglottic carcinoma was significantly higher than that in normal laryngeal mucosa. The expression of MMP-2 in metastatic lymph nodes was significantly higher than that in nonmetastatic lymph nodes (P < 0.05). The expression of E-cadherin was significantly lower in supraglottic carcinoma than that in normal laryngeal mucosa. The expression of E-cadherin was significantly lower in metastatic lymph nodes than that in nonmetastatic lymph nodes (P < 0.05). There is a negative correlation between the expression of MMP-2 and E-cadherin (r = -0.41). Predicting the lymph node metastasis of laryngeal carcinoma with the index of MMP-2(+), E-cadherin(-) and MMP-2(+), E-cadherin(-). MMP-2(+) has the highest sensitivity, but the lowest specificity and positive predictive value. MMP-2(+), E-cadherin(-) has the highest specificity and positive predictive value, but the lowest sensitivity.@*CONCLUSION@#Expression of MMP-2 and E-cadherin can be used as a marker to predict lymph node metastasis of supraglottic carcinoma. Combined the detection of MMP-2 and E-cadherin can boost the accuracy of prediction of lymph node metastasis in supraglottic carcinoma and provide efficient assistance for resecting supraglottic carcinoma.
