NCI Definition: A primary or metastatic malignant neoplasm involving the ovary. Most primary malignant ovarian neoplasms are either carcinomas (serous, mucinous, or endometrioid adenocarcinomas) or malignant germ cell tumors. Metastatic malignant neoplasms to the ovary include carcinomas, lymphomas, and melanomas. [1]

Malignant ovarian neoplasms most frequently harbor alterations in TP53, KRAS, PIK3CA, ARID1A, and CCNE1 [2].

Most Commonly Altered Genes in Malignant Ovarian Neoplasm

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 neoplasm [2].
