Implication

Analysis reveals distinct prognostic roles of MMP8 levels in colorectal cancer, suggesting implications for treatment.

Key Points

This study aims to investigate the relationship between MMP8 levels in the tumor microenvironment and serum, alongside their impact on tumor characteristics and survival outcomes in colorectal cancer.
Analyzed MMP8+ cell densities in tumor samples via immunohistochemistry and digital image analysis.
Measured preoperative serum MMP8 levels using an immunofluorometric assay.
Performed survival analyses using Kaplan-Meier method and Cox regression models.
Assessed correlations with systemic inflammatory markers and immune cell densities using linear regression models.
High tumor MMP8+ cell density correlates with favorable prognostic indicators like low disease stage and better cancer-specific survival.
Multivariable analysis indicated that low MMP8+ cell density significantly worsens prognosis with HR of 1.76 (95% CI 1.18–2.60).
Serum MMP8 levels did not correlate with MMP8 expression in tumors and were linked to systemic inflammation and poorer survival.
