Table 3 lists the means, median, and ranges of the measured concentrations. We observed statistically higher serum HE4 levels in vulvar cancer patients (90.62 pmol/L) as compared to endometrial cancer patients (56.13 pmol/L); P = 0.0106 as well as statistically higher serum HE4 levels in patients with serous (720.67 pmol/L) and endometrial (419.07 pmol/L) ovarian cancers as compared to mucinous type of ovarian cancers (136.97 pmol/L) with significance levels of P = 0.0070 and P = 0.0431, respectively. This evidence concerns the gene WFDC2 and ovarian carcinoma.
