Abstract:

Objective: To investigate the value of single detection of serum pro-gastrin-releasing peptide (ProGRP), α-fetoprotein (AFP), carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), human epididymis protein 4 (HE4) and combined detection of ProGRP, AFP and CA199 for the diagnosis of ovarian cancer. Methods: Three hundred and seventy nine suspected ovarian cancer patients, including 123 pathologically confirmed cases, admitted from January 2014 to February 2017 and another 256 patients with non-ovarian cancer served as control group were analyzed retrospectively. Serum levels of ProGRP, AFP, CA199, CA125, HE4 in the two groups were compared, and the diagnostic efficacy of single detection of ProGRP, AFP, CA199, CA125, HE4 and combined detection of ProGRP, AFP, CA199 for ovarian cancer was analyzed. ROC curves were plotted based on ProGRP, AFP, CA199, CA125, HE4, and ProGRP, AFP, CA199 combined detection. The AUC under the ROC curve were calculated. Results: The levels of serum ProGRP, AFP and CA199 in patients with stage Ⅰ and Ⅱ of the ovarian cancer were significantly lower than those in stage Ⅲ and Ⅳ(P<0.05). The levels of serum ProGRP, AFP, CA199, CA125 and HE4 of ovarian cancer group were significantly higher than those of the non-ovarian cancer group (P<0.05). The optimal cutoff values of serum ProGRP, AFP, CA199, CA125 and HE4 for diagnosis of ovarian cancer were 69.21 pg/mL, 28.95 ng/mL, 42.38 U/mL, 57.65 U/mL and 125.64 pmol/L, respectively, and the sensitivity of serum ProGRP, AFP, CA199, CA125, HE4 single detection and the combined detection of ProGRP, AFP and CA199 were 78.05%, 80.49%, 85.37%, 88.62%, 91.06% and 77.24%, respectively, the specificity were 85.94%, 86.72%, 87.89%, 90.63%, 90.23% and 97.27%, respectively, the detection accuracy were 83.37%, 84.70%, 87.07%, 89.97%, 90.50% and 90.77%, respectively. The AUC of serum ProGRP, AFP, CA199, CA125, HE4 and combined detection of ProGRP, AFP and CA199 were 0.786, 0.821, 0.897, 0.912, 0.926 and 0.948, respectively. Conclusions: Serum ProGRP, AFP, CA199, CA125, HE4 detection and combined detection of ProGRP, AFP and CA199 all have good performance in the diagnosis of ovarian cancer, and the reliability of combined detection of ProGRP, AFP and CA199 is better, which could be used for screening of ovarian cancer.
