Galectin-3 expression in human invasive pulmonary adenocarcinoma tissues. Galectin-3 positivity in tumor tissues was evaluated by immunohistochemical staining. (A) Examples of high and low staining at ×400 magnification. Scale bar, 100 µm. (B) Relapse-free survival curves for patients with invasive pulmonary adenocarcinoma. Patients with high galectin-3 expression had significantly poorer disease-free survival than those with low expression (P<0.001, log-rank test).
