A total of 90 patients with suspected primary
liver cancer admitted to our hospital from January 2016 to May 2017 were selected as the research subjects. All patients were examined by imaging and histopathology.
Enzyme-linked
immunosorbent assay (ELISA) was used to detect serum MIF, GP73 and
PIVKA-II. Automatic electrochemiluminescence immunoassay system was used to detect serum AFP and AFP-L3. The diagnostic value of single and combined detection of five serological
tumor markers for primary
liver cancer was compared and analyzed.
RESULTS: Of the 90 suspected patients with primary
liver cancer, thirty-seven were excluded and 53 were confirmed. From serum MIF diagnosis, fifty-three patients had positive results for primary
liver cancer, of which eight had false positive results, with a sensitivity of 84.91%, a specificity of 78.38%, and an accuracy of 82.22%, respectively. From serum GP73 diagnosis, fifty-six patients had positive results for primary
liver cancer, of which 10 had false positive results, with a sensitivity of 86.79%, a specificity of 72.97%, and an accuracy of 81.11%, respectively. From serum
PIVKA-II diagnosis, 48 patients had positive results for primary
liver cancer, of which seven had false positive results, with the sensitivity of 77.36%, the specificity of 81.08%, and the accuracy of 78.89%, respectively. From serum AFP-L3 diagnosis, fifty-two patients had positive results for primary
liver cancer, of which nine had false positive results, with a sensitivity of 81.13%, a specificity of 75.68%, and an accuracy of 78.89% respectively. From serum AFP diagnosis, 57 patients had positive results for primary
liver cancer, of which seven had false positive results, with a sensitivity of 83.02%, the specificity of 81.08%, and an accuracy of 82.22%, respectively. From the combined diagnosis of 5 serological
tumor markers, fifty-three patients had positive results for primary
liver cancer, of which one had a false positive result, with a sensitivity of 98.11%, a specificity of 97.30%, and an accuracy of 97.78%, respectively. Combined diagnosis has significantly higher sensitivity, specificity and accuracy than a single diagnosis (P<0.05).
CONCLUSION: Serum MIF, GP73,
PIVKA-II, AFP-L3 and AFP all have certain diagnostic value for primary
liver cancer; the combined detection of five serological
tumor markers can significantly improve the sensitivity, specificity and accuracy of the diagnosis of primary
liver cancer, with higher diagnostic value.
