[Relationship between expression of MMP-2 and prognosis in human laryngeal squamous cell carcinoma].
OBJECTIVE
In order to evaluate the potential of matrix metalloproteinase 2(MMP-2) as a prognostic factor for human laryngeal squamous cell carcinoma (HLSCC).


METHODS
Seventy-three surgical specimens from patients with HLSCC were reviewed retrospectively regarding MMP-2 expression via immunohistochemistry. Immunostaining was performed using a streptavidin-biotin peroxidase complex technique. The patients were followed-up till June 2014 and the relationship between MMP-2 and clinical data including age, gender, metastasis, clinical type, pathological type, lymph node metastasis and prognosis were analyzed using SPSS 19.0.


RESULTS
The positive expression rate of MMP-2 in 73 patients was 57.53% (42/73). Kaplan-Meier analysis demonstrated statistically significant difference for 5-year overall survival rate between the group with positive and negative MMP-2 expression,the 5-year overall survival rate were 76.0% and 57.5% respectively in the group with negative and positive MMP-2 expression. The site of the primary tumor, clinical stage, lymph node metastasis and T grade were related to the prognosis of HLSCC (P were 0.002, 0.009, 0.034 and 0.001 respectively), and there was no significant correlation between age, sex, pathological differentiation and prognosis of HLSCC.


CONCLUSIONS
MMP-2 was related with worse overall disease survival and could be considered as a potential marker of poor prognosis.
