OGCT is a rare tumour under the scope of ovarian cancer, accounting for less than 5% of all ovarian malignancies. It occurs mostly in 15-19-year-old women and shows 75% incidence rate for women aged <30 years. [31] In 2011, the number of new cases occurred worldwide is 5.3 per million. [32]
Cystadenocarcinoma is a malignant form of a cystadenoma and is a cancer derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness, and local extension and metastases occur.

[13] [22] It is recommended that women with an RMI score over 200 should be referred to a centre with experience in ovarian cancer surgery. [23] The RMI is calculated as follows: [23]

[ 2 ] [ 3 ] The staging system for these tumours is the same as for epithelial tumours and most present as stage I. [ 4 ] The peak age at which they occur is 50–55 years, but they may occur at any age.
Papillary serous cystadenocarcinomas are the most common form of malignant ovarian cancer making up 26 percent of ovarian tumours in women aged over 20 in the United States. [ 1 ] As with most ovarian tumours, due to the lack of early signs of disease these tumours can be large when discovered and have often metastasized , often by spreading ...
