NCI Definition: A primary or metastatic malignant neoplasm involving the peritoneum. Representative examples include carcinoma and malignant mesothelioma. [1]

Malignant peritoneal neoplasms most frequently harbor alterations in TP53, KRAS, EPHB1, BRCA2, and BCOR [2].

Most Commonly Altered Genes in Malignant Peritoneal Neoplasm

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