Study Population

The study will be carried out in patients with primary and recurrent EOC considered eligible for treatment with surgery, chemotherapy and/or immunotherapy.

You may qualify if:

  • Patients with (suspicion of) primary or recurrent EOC with an indication for surgery, chemotherapy and/or immunotherapy.
  • Age ≥18 years.
  • WHO performance status 0-2.
  • Accessible for treatment and follow-up.
  • Written informed consent.

You may not qualify if:

  • Other active malignancy in past 5 years prior to entry into the study, except for treated non-melanoma skin cancer.
  • Any known severe infection like HIV, hepatitis A, B and C.
  • Receiving immune suppressive treatment.
  • Medical or psychological condition which in the opinion of the investigator would not permit the patient to complete the study or sign meaningful informed consent.
