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. In 2011, the number of new cases occurred worldwide is 5.3 per million. In most countries, the occurrence rate on average is less than 3% of the population. However, Asia has reported the highest proportion of cases up to 4.3% due to the younger age profile of the population. For other regions, the incidence rates reported are 2.5% in Oceania, 2.0% in North America and 1.3% in Europe. The five-year survival rates have reached up to 90-92%, which is much higher than that of epithelial ovarian cancers. The main reason is the high effectiveness of platinum-based chemotherapy.
