Background
The aim of this study is to evaluate a new tumour marker, HE4, and to compare it with CA125 in predicting optimal cytoreduction and response to chemotherapy. Thirty patients with advanced epithelial ovarian cancer and multiple sera harvested during neoadjuvant chemotherapy (NAC) were included.
Results
Based on ROC curves analysis, CA125 ≤ 75 UI/ml and HE4 ≤ 252 pmol/L after the 3rd cycles of NAC, with a sensitivity of 93.7 % and a specificity of 92.3 % (PPV = 93.7 % and NPV = 92.3 %), offered the best combination for predicting optimal cytoreduction. In addition, the HE4 value of 115 pmol/L is the best cut-off level for identifying platinum-sensitive patients.
Conclusions
The introduction of HE4 as a new tool for predicting platinum-sensitivity and interval optimal cytoreduction is promising.
