Abstract
Stanniocalcin2 (STC2) is associated with proliferation, invasion, and metastasis in various cancers. We examined the clinical significance of STC2 mRNA expression in patients with colorectal cancer (CRC). Relative expression levels of STC2 mRNA in CRC tissues and corresponding normal mucosa obtained from 202 patients were measured using quantitative real-time reverse transcriptase-polymerase chain reaction. Expression of STC2 mRNA was higher in the cancer tissue than in the adjacent normal mucosa. STC2 mRNA expression in cancer tissues was associated with tumour size, liver metastasis, venous invasion, and lymph node metastasis. High expression of STC2 mRNA was significantly associated with poorer postoperative survival (p=0.0003). Multivariate analysis showed that high expression of STC2 mRNA was an independent predictor of postoperative survival. High expression of STC2 mRNA in CRC tissue may be a useful prognostic marker in patients with CRC.
