As opposed to ovarian cancers which have been extensively studied and characterized by high levels of genetic instability and frequent mutations of TP53 (Jarboe et al., 2008; Kurman and Shih Ie, 2011), primary serous peritoneal cancers are less frequently investigated (Jordan et al., 2008; Nik et al., 2014) and are thought to share a common aetiology with ovarian cancers based on their close histological and clinical similarities (Kessler et al., 2013). This evidence concerns the gene TP53 and ovarian cancer.
