Integrin αvβ6 and matrix metalloproteinase 9 correlate with survival in gastric cancer

Figure 2 Kaplan-Meier plots show the association of survival and expression of integrin αvβ6 and MMP-9 in all gastric cancer patients tested. A: Positive expression of αvβ6 was associated with decreased survival (P = 0.000); B: The same tendency was present in matrix metalloproteinase 9 (MMP-9) positive expression cases (P = 0.000); C: When αvβ6 and MMP-9 alterations were analyzed together, patients with both αvβ6 and MMP-9 positive expression experienced the highest mortality of the four groups (P = 0.000).
