Loss of stromal caveolin-1 expression in colorectal cancer predicts poor survival

Figure 1 Immunohistochemical staining for caveolin-1. High caveolin-1 (CAV-1) expression in colorectal cancer stroma (A: × 200; B: × 400). Panel C (× 200) shows moderate stromal CAV-1 expression, and panel D (× 200) shows negative stromal CAV-1 expression. Panel E (× 200) depicts normal colorectal tissue. Panel F (× 400) demonstrates CAV-1 expression in colorectal tumor cells.

Figure 2 Kaplan-Meier curves of overall survival and disease-free survival. Patients with high stromal caveolin-1 expression have good overall survival (A) and disease-free survival (B).
