Hypothesis
Can serum CEA testing improve the detection of recurrence in colorectal cancer patients after surgery?
Conclusion
Regular serum CEA testing can predict clinical recurrence in most colorectal cancer patients after surgery.
Supporting Evidence
- 58.4% of patients remained free of recurrence with normal CEA levels.
- 14.2% had temporary rises in CEA without recurrence.
- 82% of hepatic recurrences had a preceding rise in CEA.
Takeaway
Doctors can use a blood test called CEA to check if cancer comes back after surgery for colorectal cancer.
Methodology
The study followed 663 patients with colorectal cancer using serial serum CEA measurements alongside routine clinical surveillance.
Potential Biases
Potential selection bias due to surgeons not entering all eligible patients.
Limitations
Some patients were lost to follow-up, and not all eligible patients were entered into the study.
Participant Demographics
Patients were under 70 years old, with a mean age of 59, including 367 males and 296 females.
