The p-values for other clinicopathological parameters were as follows: patient age mean ± SD: 0.355; serum KLK10 (ng/ml) mean ± SD: 0.798; serum KLK6 (ng/ml) mean ± SD: 0.278; ascites (absent and present): 0.106; disease grade (1, 2, and 3): 0.622; pathology subgroup (epithelial, nonepithelial and metastatic): 0.402; and epithelial pathology subtype (serous, mucinous, endometrioid and clear cell carcinoma): 0.735. This evidence concerns the gene KLK6 and clear cell adenocarcinoma.
