Abstract Cripto‐1 (CR‐1) is related to the biological behaviour and prognosis of carcinomas. The purpose of this study was to investigate the significance of CR‐1 expression in surgically resected stage I non‐small cell lung cancer (NSCLC). One hundred and forty‐eight patients with completely resected stage I NSCLC and available clinical follow‐up data were assessed. The protein expression of CR‐1 in the tumours was detected by immunohistochemistry. CR‐1 was highly expressed in 64 of 148 tumours. Among patients with high CR‐1 expression, progression‐free survival and overall survival rate were significantly lower than those of patients with low CR‐1 levels ( P = .013 and P = .019, respectively). The incidence of distant metastasis in patients with high CR‐1 expression was significantly higher than that of in patients with low CR‐1 expression (57.13% vs 21.43%, P = .001). The results of the multivariate analysis confirmed that a high CR‐1 was a significant factor for poor prognosis. In conclusion, CR‐1 could be a useful prognostic factor in patients with stage I NSCLC, likely as an indicator of the metastatic propensity of the tumour.
