Abstract
Albumin to fibrinogen ratio (AFR) play a crucial role in the progression and prognosis of many malignant tumors. This study aimed to comprehensively assess the diagnostic value of AFR as single markers or in combination with squamous cell carcinoma antigen (SCC-Ag), cancer antigen 125 (CA-125) in cervical cancer. A total of 323 cervical cancer inpatients, 143 patients with cervical intraepithelial neoplasia (CIN) and 317 healthy controls were analyzed. Differences in laboratory parameters and clinicopathological features were calculated using the Mann-Whitney U or Kruskal-Wallis H test. The receiver operating characteristic (ROC) curve was used to evaluate the predicted value of AFR, alone or combined with SCC-Ag, CA-125 for the diagnosis of cervical cancer. The levels of AFR in patients with cervical cancer were significantly lower than those in the CIN patients and the control subjects. AFR were not only negatively correlated with the tumor stage, but also related to histology typing, lymph node metastasis, distant metastasis, depth of stromal infiltration, tumor size, and tumor stage; however, it was not associated with the blood group. AFR combined with SCC-Ag possessed a larger area under the curve (AUC; AUCAFR+SCC-Ag = 0.924, 95% confidence interval (CI) 0.900, 0.944) than AFR (P < 0.001), SCC-Ag (P < 0.001), or CA-125 (P < 0.001) did alone. The pretreatment levels of AFR, alone or combined with SCC-Ag, CA-125 could improve the diagnostic efficiency of cervical cancer.
