This study was designed to evaluate the survivin expression in colorectal tissues and to investigate whether the survivin expression is associated with the clinicopathologic characteristics and the patient survival. <b>Methods:</b> Immunohistochemical analysis of survivin was performed using the tissue microarrays of 622 colorectal tissue samples from 529 colorectal adenocarcinomas, 40 normal mucosa, 34 adenomatous polyps, and 59 metastatic lymph nodes. <b>Results:</b> Normal colorectal mucosa were completely negative for survivin (0/40, 0%), but survivin was expressed in adenomatous polyps (8/34, 23.5%), adenocarcinomas (327/529, 61.8%), and metastatic lymph nodes (27/59, 45.8%). In the analyses between the survivin expression and clinicopathologic parameters, the survivin expression was correlated with tumor location in colon (<i>P</i>= 0.026), lymph node metastasis (<i>P</i>= 0.003) and American Joint Committee on Cancer (AJCC) stage (<i>P</i>= 0.040).
