Blood CEA levels for detecting recurrent colorectal cancer (Protocol)
Nicholson BD., Shinkins B., Pathiraja I., Roberts NW., James TJ., Mallett S., Perera R., Primrose JN., Mant D.
The objectives are: 1) To determine the accuracy of single-measurement blood CEA as a triage test to prompt further investigation for CRC recurrence after curative resection and 2) to identify sources of between- and within-study heterogeneity to inform potential subsequent analyses.
