The clinical significance of monitoring carbohydrate antigen CA50 in colorectal carcinoma

摘要

In order to investigate the possible involvement of the antigen CA50 in patients with col- orectal carcinoma, the carbohydrate antigen CA50 serum value was examined in 30 normal individu- als, 27 patients with benign colorectal diseases and 66 patients with colorectal corcinoma by immuno- radiometric assay(IRMA). The results showed that the serum CA50 value in patients with colorectal carcinoma was significantly higher than that in patients with benign colorectal diseases or in normal control group (P < 0.01). It significantly declined after radical operation was performed (P < 0.01).
