Smurf2 expression in primary CRC and the long-term outcome based on the Smurf2 expression. Immunohistochemistry analysis for Smad ubiquitination regulatory factor 2 (Smurf 2) expression in (a, b) primary colorectal cancer (CRC). Scale bar = 200 µm (a) and 100 µm (b). (c) Representative images of each score evaluating Smurf2 expression in primary CRC. Scale bar = 200 µm (c). The Kaplan–Meier analysis for (d) overall survival, (e) time to liver metastasis, and (f) time to surgical failure based on the Smad ubiquitination regulatory factor 2 (Smurf 2) expression in primary CRC.
