  1. aWomen with ovarian cancer diagnosis after 2001 were excluded due to incomplete survival data.
  2. bHigh-risk epithelial tumours included serous and endometroid adenocarcinomas, anaplastic, small cell and poorly differentiated carcinomas.
  3. cMedium-risk epithelial tumours included mucinous adenocarcinomas, clear cell carcinomas and mesonefroid cancers.
