NCI Definition: A rare, serous adenocarcinoma that arises from the lining of the peritoneum. It affects females. The clinical behavior and pathologic characteristics are similar to the serous adenocarcinoma that arises from the ovary. [1]

Primary peritoneal serous adenocarcinomas most frequently harbor alterations in TP53, KRAS, EPHB1, BRCA2, and BCOR [2].

Most Commonly Altered Genes in Primary Peritoneal Serous Adenocarcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, TP53fs, and TP53 Exon 8 Mutation are the most common alterations in primary peritoneal serous adenocarcinoma [2].
