Brief Summary
This is prospective, multicenter, randomised phase III trial among women with endometrial cancer with high-intermediate risk features to investigate the role of an integrated clinicopathological and molecular risk profile to determine if participants should receive no adjuvant therapy, vaginal brachytherapy or external beam radiotherapy based on a favourable, intermediate or unfavourable profile as compared to standard adjuvant vaginal brachytherapy.

Study Arms (2)
Molecular profile based treatment
EXPERIMENTALDetermination of the integrated clinicopathological and molecular profile to determine adjuvant treatment: observation for favourable profile; vaginal brachytherapy for intermediate profile; external beam radiotherapy for unfavourable profile
Vaginal brachytherapy
ACTIVE COMPARATORAdjuvant vaginal brachytherapy (standard treatment)
Interventions
Internal radiation of the vaginal vault using a vaginal cylinder, 21 Gy in 3 out-patient sessions over 2 weeks
External beam pelvic radiotherapy on a linear accelerator, 48.6 Gy in 27 out-patients sessions over 5.5 weeks
No radiation therapy, but active follow-up and quality of life questionnaires as in the groups who have adjuvant treatment
Eligibility Criteria
You may qualify if:
- Histologically confirmed endometrioid type endometrial carcinoma, International Federation of Gynecology and Obstetrics (FIGO) 2009 stage I, with one of the following combinations of stage, grade, age, and lymph-vascular space invasion (LVSI):
- Stage IA, grade 3 (any age, with or without LVSI)
- Stage IB, grade 1 or 2 and age \>60 years
- Stage IB, grade 1-2 with documented LVSI
- Stage IB, grade 3 without LVSI
- Stage II (microscopic), grade 1
- World Health Organization (WHO)-performance status 0-2
- Written informed consent
You may not qualify if:
- Any other stage and type of endometrial carcinoma
- Histological types serous carcinoma or clear cell carcinoma (at least 10% if mixed type), or undifferentiated or neuroendocrine carcinoma
- Uterine sarcoma (including carcinosarcoma)
- Previous malignancy (except for non-melanomatous skin cancer) \< 5 yrs
- Previous pelvic radiotherapy
- Expected interval between the operation and start of radiotherapy exceeding 8 weeks
