It is noteworthy that two survival markers—ZNF667-AS1 and SEMA3B-AS1—are undoubtedly of clinical significance, since they both also showed the most statistically significant (p < 0.001) increase in methylation level in EOC progression, including peritoneal metastases, metastases in total, advanced stages (III–IV), larger tumor size and extent (T3), and a higher histological grade of malignancy (G3–G4). Here, ZNF667 is linked to neoplasm.
