AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for women with early-stage endometrial cancer (stage I or II) who have a high risk of the cancer coming back. It tests whether removing lymph nodes during surgery helps people live longer.
- Age
- 18 to 75 years
- Sex
- Women only
- Disease stage
- Endometrial cancer, clinical stage T1b or T2 (all types), or stage T1a grade 3 endometrioid, mucinous, serous, clear cell type, or carcinosarcoma. No bulky lymph nodes.
- Earlier treatment
- No earlier surgery for this cancer, or surgery after hysterectomy within 8 weeks if no lymph nodes were removed. No earlier chemotherapy, radiotherapy or hormone therapy for this cancer.
Main reasons for not taking part
- Stage T1a grade 1 or 2 endometrioid-type tumours
- Cancer of FIGO stage III or IV (except tiny lymph node spread seen only under a microscope)
- Cancer that has come back, or signs of disease outside the womb
- Known HIV infection or AIDS
- Illness or medicines that make surgery or chemotherapy unsafe

- Original description
The primary aim of this trial is to ascertain whether or not systematic pelvic and para-aortic lymphadenectomy (LNE) does have a significant impact on overall survival (OS) in patients with endometrial cancer (EC) FIGO Stages I or II and high risk of recurrence. Secondary aims will be to evaluate the effect of LNE on disease free survival (DFS) and quality of life, as well as the complications and side effects of LNE and the number of resected lymphnodes. 640 patients with histologically confirmed EC with high risk of recurrence (stage pT1b - pT2, all histological subtypes; pT1a, G3 endometrioid or serous or clear cell EC or carcinosarcomas) will be randomized. In Arm A, a total hysterectomy and bilateral salpingo-oophorectomy and in case of serous or clear cell EC additionally an omentectomy will be performed. In arm B in addition a systematic pelvic and para-aortic LNE up to the level of the left renal vein will be performed.Read full original descriptionShow less
Pelvic and Para-aortic Lymphadenectomy in Patients With Stage I or II Endometrial Cancer With High Risk of Recurrence
The primary aim of this trial is to ascertain whether or not systematic pelvic and para-aortic lymphadenectomy (LNE) does have a significant impact on overall survival (OS) in patients with endometrial cancer (EC) FIGO Stages I or II and high risk of recurrence. Secondary aims will be to evaluate the effect of LNE on disease free survival (DFS) and quality of life, as well as the complications and side effects of LNE and the number of resected lymphnodes. 640 patients with histologically confirmed EC with high risk of recurrence (stage pT1b - pT2, all histological subtypes; pT1a, G3 endometrioid or serous or clear cell EC or carcinosarcomas) will be randomized. In Arm A, a total hysterectomy and bilateral salpingo-oophorectomy and in case of serous or clear cell EC additionally an omentectomy will be performed. In arm B in addition a systematic pelvic and para-aortic LNE up to the level of the left renal vein will be performed.
Inclusion: histologically confirmed EC of clinical stages T1b and T2 (all histological types) and stage T1a G3 type 1 (endometrioid, endometriod with squamous differentiation, mucinous) or type 2 tumors (any percentage of serous or clear cell component) or carcinosarcoma; a) no previous surgery concerning EC (primary surgery) or b) surgery after hysterectomy (e.g. for presumed low risk endometrial cancer) is allowed within 8 weeks after hysterectomy if no LNE was performed (secondary surgery); absence of bulky lymph nodes; performance status ECOG 0-1; age 18 - 75 years; written informed consent; adequate compliance.
Exclusion: preceding chemo-, radio, or endocrine therapy for EC; any concomitant disease not allowing surgery including lymphadenectomy and/or chemotherapy; sarcomas (except for carcinosarcoma = malignant mixed Müllerian tumor); evidence of extrauterine disease by visual inspection; any current medication containing considerable surgical risk (e.g. bleeding: due to oral anticoagulating agents); any known disorder or circumstances making participation in trial and follow-up questionable. Insufficient compliance is expected; patients with second malignancies if disease or treatment might have an impact on the patient's prognosis; known HIV-infection or AIDS; stage pT1a, G1 or G2 tumors of type 1 histology; EC of FIGO stages III or IV (except for microscopical lymph node metastases); recurrent EC; any medical history indicating excessive peri-operative risk; simultaneous participation in other clinical trials if not permitted by the steering committee (translational or QoL studies not interfering with the objectives of ECLAT are allowed).
