ABSTRACT
Laryngeal carcinoma (LC) is reported to have a higher incidence rate among all types of head and neck cancers around the globe. Mechanisms resulting in the pathogenesis of LC are complicated due to involvement of invasion and metastasis and there is a need to understand this complicated multistep process. Numerous molecules including matrix metalloproteinases (MMPs) are involved in regulating metastatic mechanisms. Furthermore, activation and expression of different classes of MMPs have been observed in multiple pathological and physiological events including inflammation, invasion, and metastasis. Among all members of MMPs, matrix metalloproteinases-2 (MMP-2), and matrix metalloproteinases-9 (MMP-9) have been frequently reported to correlate with tumor pathogenesis. The present study is designed to check the involvement of MMP-2 and MMP-9 in LC pathogenesis. 184 laryngeal tumor samples along with adjacent uninvolved healthy sections were collected to check the expression deregulation of the above-mentioned gene in LC using real-time PCR and immunohistochemistry (IHC). Real-time PCR and IHC analyses showed the significant upregulation of MMP-2 (Pâ
<â
.0001) and MMP-9 (Pâ
<â
.0001) genes in laryngeal tumors compared to controls. Spearman correlation showed the positive correlation of expression deregulation of selected MMPs with advanced TNM stage [MMP-2, (Pâ
<â
.0001); MMP-9, Pâ
<â
.0001] and smoking status [MMP-2 (Pâ
<â
.0001); MMP-9 Pâ
<â
.0001] in laryngeal pathogenesis. Receiver operating curve (ROC) analysis showed the good diagnostic/prognostic value of said markers in laryngeal cancer patients. The present study showed that significant upregulation of selected MMPs was found associated with an increased risk of laryngeal cancer and can act as good diagnostic markers for the detection of said disease.
