Brief Summary
This is a prospective, multicenter, randomized phase III trial among women with endometrioid adenocarcinoma with high-intermediate and intermediate risk features to investigate the role of integrated genomic-pathologic classification to determine if participants should receive no adjuvant therapy, vaginal brachytherapy, external beam radiotherapy or chemo-radiation therapy based on molecular features as compared to standard radiation therapy.

Study Arms (2)
Molecular profile based treatment
EXPERIMENTALDetermination of the integrated genomic-pathologic profile to determine adjuvant treatment: observation for POLE-mutated profile; vaginal brachytherapy for intermediate profile; chemo-radiotherapy for p53-abnormal profile.
Radiotherapy
ACTIVE COMPARATORAdjuvant vaginal brachytherapy for intermediate risk (stage I A with G3 or stage I B with G1-2) and external beam pelvic radiotherapy for high-intermediate risk (stage I B with G3, or stage II) (standard treatment)
Interventions
Internal radiation of the vaginal vault using a vaginal cylinder. For brachytherapy administered alone it is recommended: suggested dose is either 3 fractions of 7 Gy or 5 fractions of 6 Gy. For brachytherapy administered after completion of External beam radiotherapy (EBRT): Total dose should aim to be 65 Gy, and suggested dose is 2-3 fractions of 5-6 Gy
External beam pelvic radiotherapy on a linear accelerator, 45-50 Gy in 25-28 out-patients sessions
No adjuvant therapy, but active follow-up and quality of life questionnaires as in the groups who have adjuvant treatment
4 adjuvant cycles carboplatin and paclitaxel followed by External beam pelvic radiotherapy (45-50 Gy )
