Objectives: To study the expression of Matrix metalloproteinases 2 and 9 in laryngeal squamous cell carcinoma and their correlation with short term outcome.
Study Design: In a prospective study of 15 patients with LSCC hospitalized in a tertiary center, RT-PCR was used to examine the expression of MMP-2 and MMP-9 in tissue samples post-surgery and results were compared to clinicopathological features and prognosis.
Results: The positive expression of MMP-2 and MMP-9 in patients with LSCC was 86.66% whereas 13.33% showed decrease. MMP-2 and MMP-9 were increased in patient with Stage IV A (1 patient) and 85.7% of patients (12 patients) in Stage III showed increase in MMP-2 and MMP-9 and 14.3% (2 patients) showed decrease. Patients with metastatic lymph nodes showed 100% increase in MMP-2 and MMP-9 whereas patients with non-metastatic lymph nodes showed 92.3% increase and 7.7% decrease in MMP-2 and MMP-9. No significant association was found between nodal disease and stage and mmp-2 and mmp-9 (p = 0.551 and 0.685 resp.). The association between decrease in MMP-2 and MMP-9 to well differentiated and increase in MMP-2 and MMP-9 to poor differentiation was found to be significant (p = 0.03). The association between MMP-2 and MMP-9 upregulation and recurrence in follow up was not found to be statistically significant (p = 0.685).
Conclusion: The results of the present study indicate that the expression of both MMP-2 and MMP-9 are up-regulated in laryngeal cancers with 100% survival in shorter outcome of 6 months.
