Gynaecological Oncology

The department of Gynaecological Oncology conducts studies on pre-malignancies, vulva-, cervical, ovarian and endometrial cancer. The studies are embedded in the ACE Gynaecological Tumours and are rolled out in the South-West Netherlands region.

About our department

Our research

We are initiators of the following studies:

  • Pre-malignancies: we run multicenter studies on the pre-malignant cervix and HPV (Vaccin; Topic-2 trial), on the pre-malignant endometrium (the EIN study) and Foto Dynamic Therapy on Lichen Sclerosus and Vulvar Intraepithelial Neoplasia.
  • Vulva-cancer: we conduct a multicenter-study on recurrent vulvar cancer and the feasibility and safety of a re-sentinel node procedure.
  • Ovarian cancer: the PlaComOv study is a placebo-controlled RCT on a new technique for cytoreductive surgery in ovarian cancer. Primary outcome is the percentage of obtained complete surgery. A translational study linked to the PlaComOv study is looking into therapy resistance in ovarian cancer via RECAP tests, ct-DNA and sequencing studies.
  • Endometrial cancer: a prospective study on carcinosarcomas of the uterus (CUS) addresses risk factors and quality of life of patients with carcinosarcoma of the uterus. In all cases of endometrial cancer we look into damage repair mechanisms using RECAP tests.
  • Genetic gynaecological cancers: we study the Lynch Syndrome and BRCA1 and BRCA2 gynaecological cancers. We participate in several studies initiated by other centers, such as the OVHIPEC-2 study, the GERSOC study for ovarian cancer, the Granulosa study and Fertility Preservation study, the Sparc study on sexuality of women treated with chemoradiation for cervical cancer, and studies in BRCA mutation carriers.

Principal Investigators

  • Dr Heleen van Beekhuizen is principal investigator in the PlaComOv, Vaccin, Topic-2 and CUS studies.
  • Dr Lena van Doorn is principal investigator in the V2SLN, EIN and endometrium damage repair studies.

Carcinosarcoma of the Uterus

A prospective observational study in patients with carcinosarcoma of the uterus (CSU) in South-West Netherlands.

DNA damage response in tumours of patients with endometrial cancer

Ideally in the future, after a preclinical test on a tumour sample of an individual patient, a patient-tailored therapy will be chosen with the best perspectives thereby avoiding non-active therapies. An important advantage would be a less toxic treatment with fewer side effects for the patient, which could potentially be repeated depending on specific biological targets.

Endometrial Intraepithelial Neoplasia (EIN) study

We study the accuracy of the EIN diagnosis in office-based endometrial sampling; i.e., aspiration sampling devices and hysteroscopy, and the risk of a malignancy after such diagnosis.

TopIC-2: Imiquimod in recurrent CIN

We investigate the efficacy of imiquimod in recurrent and residual CIN lesions with the aim to avoid further excisional therapy with risk of complications.

We study the feasibility and safety of the sentinel node procedure in recurrent vulvar cancer.

VACCIN study

Adjuvant VACcination against HPV in surgical treatment of CIN lesions, a Randomised Controlled Trial’. Limited data shows that prophylactic HPV vaccination after a loop electrosurgical excision procedure (LEEP) reduces the chance of recurrence of CIN lesions in cervical cancer.
