ABSTRACT
Objective To evaluate the value of serum tumor markers in diagnosis of over 80 years old patients with colorectal cancer.Methods Serum CA199,CA242 and CEA of 68 cases senile patients with colorectal cancer and 35 cases senile patients with benign large intestinal diseases were detected by ELISA.Results Serum levels of CA199,CA242 and CEA in patients with colorectal cancer were (37.95 ± 15.95 ) U/ml,( 50.08 ± 24.20 ) U/ml,( 22.34 ± 17.35 ) μg/L respectively and were significantly higher than that in patients with benign large intestinal diseases CA199 ( 10.73 ± 6.27 ) U/ml,CA242 ( 8.00 ± 3.52 ) U/ml,CEA(2.32 ± 1.01 )μg/L.In addition,the level of these three markers was increased with the progress of colorectal cancer and the sensitivity of diagnosis was related with the stages of colorectal cancer.Parallel combined testing methods increased the diagnostic sensitivity to 83.6%,and serial combined testing increased the diagnostic specificity to 88.7 %.Conclusions Serum tumor markers showed certain values in the diagnosis of the senile patients with colorectal carcinoma.Furthermore,the combined determination of tumor markers is helpful for early diagnosis of colorectal cancer and increases the sensitivity and specificity in diagnosing of colorectal carcinoma.
