CEA as a blood-based biomarker in anal cancer which reported that the mean Carcinoembryonic Antigen (CEA) among subgroups by clinical status at the time of presentation to our institution was highest among those patients with metastatic Squamous cell carcinoma of the anal canal (SCCA) to visceral organs, however this finding was not statistically significant by ANOVA .
By clinical subgroup, the percentage of patients with an abnormally elevated CEA was highest in those patients with metastatic disease to lymph nodes followed by recurrent/unresectable SCCA , and metastatic SCCA to visceral organs, and was statistically significant between groups.
