NCI Definition: An invasive malignant neoplasm that arises from the ovary and is characterized by the presence of malignant epithelial cells that, in well differentiated tumors, resemble the epithelium of the fallopian tube or, in poorly differentiated tumors, show anaplastic features and marked nuclear atypia. It includes serous adenocarcinoma and serous adenocarcinofibroma. [1]

Malignant ovarian serous tumors most frequently harbor alterations in TP53, CCNE1, KRAS, BRCA1, and NF1 [2].

Most Commonly Altered Genes in Malignant Ovarian Serous Tumor

TP53 Mutation, TP53 Missense, TP53 c.217-c.1178 Missense, TP53 Exon 5 Mutation, and TP53 Exon 8 Mutation are the most common alterations in malignant ovarian serous tumor [2].
