To assess the efficacy of systematic pelvic and para-aortic lymphadenectomy in patients with advanced ovarian cancer and intra-abdominal complete debulking.

Secondary: progression-free survival, complications and quality of life; Exploratory: Role of number of resected lymph nodes for primary and secondary objectives

Condition Intervention Phase
Ovarian Cancer Procedure: No Lymphadenectomy (LNE) Procedure: Lymphadenectomy (LNE) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Randomized, Multicentre Trial for Lymphadenectomy In Ovarian Neoplasms

Primary Outcome Measures:
  • Overall Survival [ Time Frame: time from randomization until death ]

Secondary Outcome Measures:
  • - Progression-free survival (PFS) - Quality of life (QoL) as measured by EORTC QLQ-C30, OV28 - number of resected lymph nodes [ Time Frame: Progression-free survival time is calculated from the date of surgery until the date of first progressive disease or death, whichever occurs first or date of last contact (censored observation). ]

Estimated Enrollment: 640
Study Start Date: December 2008
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: A Procedure: No Lymphadenectomy (LNE)
No lymphadenectomy is performed in patients of the control group
Experimental: B Procedure: Lymphadenectomy (LNE)
Patients allocated to the lymphadenectomy group undergo systematic lymphadenectomy in addition to surgery for complete resection. Complete mobilization of the colon by resection of the paracolic gutters is necessary for the preparation of the lymphadenectomy. Afterwards the peritoneum has to be opened until the Treitzsche's Band for visualization of the renal vein. Systematic pelvic and para-aortic lymphadenectomy is based on anatomical studies and defined according to a recently published single centre series as systematic resection of lymph nodes in the following regions [24, ].


Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Primary diagnosis of invasive epithelial ovarian cancer FIGO stage IIB-IV (IV only if resectable metastasis in pleura, liver, spleen, and/or abdominal wall)
  • Macroscopic complete resection
  • Age: 18 - 75 years
  • Patients who have given their signed and written informed consent
  • Good performance status (ECOG 0/1)

Exclusion Criteria:

  • Non epithelial ovarian malignancies and borderline tumors
  • Intraoperative clinically suspicious lymph nodes (bulky nodes)
  • Secondary invasive neoplasms in the last 5 years (except synchronal endometrial carcinoma FIGO IA G1/2, non melanoma skin cancer, breast cancer T1 N0 M0 G1/2) or with any signs of relapse or activity.
  • Recurrent ovarian cancer
  • Prior chemotherapy for ovarian cancer or abdominal/pelvic radiotherapy
  • Diseases of the lymph system (including lymph edema of unknown origin)
  • Clinical relevant dysfunctions of blood clotting (including medicamentous conditioned reasons, e.g. ASS, if not stopped at least 7 days prior to surgery)
  • Any significant medical reasons, age or performance status that will not allow to perform the study procedures (estimation of investigator)
  • Prior retroperitoneal lymph node dissection (systematic or sampling)
  • Pregnancy
  • Dementia or significantly altered mental status that would prohibit the understanding and giving of informed consent
  • Any reasons interfering with regular follow-up
