Relationship between prognosis and glucose transporter-1 and Ki-67 expression in obstructive colon cancer pre and post stent placement

Figure 1 Representative images of glucose transporter-1 and Ki-67 immunohistochemistry in malignant large bowel obstruction. A and B: Low and high glucose transporter-1 within the tumor microenvironment; C and D: Low and high Ki-67 within the tumor microenvironment. (magnification: 200 ×).

Figure 2 Kaplan-Meier curves of recurrence-free interval with glucose transporter-1 in malignant large bowel obstruction. A: Kaplan-Meier curves demonstrating that tumor glucose transporter-1 (GLUT-1) expression is associated with 3-year recurrence-free interval (RFI) in pre-self-expandable metallic stent (SEMS) biopsies (P = 0.026); B: Kaplan-Meier curves demonstrating that tumor GLUT-1 expression is associated with 3-year RFI in post-SEMS surgical tissues (P = 0.001). GLUT-1: Glucose transporter-1; SEMS: Self-expandable metallic stent.
