The upregulation of fecal cytokeratin 19 (CK19) correlates with age and metastatic status in human colorectal cancer (CRC). To further explore its clinical significance in older patients (>60 years), their fecal CK19 was measured by quantitative reverse transcription-polymerase chain reaction. Differences in CK19 transcripts were compared using the nonparametric Mann-Whitney U test. Clinical significance was assessed with the chi-squared test and a binary logistic regression model. The association between overall survival and expressions of fecal CK19 in combination with other serum markers, carcinoembryonic antigen and carbohydrate antigen 19-9 (CA19-9), was evaluated using the Kaplan-Meier method. In these older groups, CRC patients had significantly higher median fecal CK19 expression (p=0.006) than controls. The highest risk of CRC (odds ratio, 5.8; 95% confidence interval, 2.3-14.7; p
