- Molecular integrated risk profile is a stronger risk stratification model with
improved risk prediction
- Decrease overtreatment and undertreatment

New PORTEC-4a trial design
- Molecular integrated vs standard indications for adjuvant treatment:
Endometrial carcinoma Surgery and pathology diagnosis FIGO 2009 – high intermediate risk Stage IA (with invasion), any age and grade 3 (with or without LVSI) Stage IB, grade 1-2 and age > 60 Stage IB, grade 1-2 and LVSI+ Stage IB, grade 3 without LVSI Stage II (microscopic), grade 1 Randomisation

PORTEC-4a - started June 1st 2016
- Pilot phase: N = 50 (Netherlands)
- Endpoints: logistics, patient acceptance
- Proceed into full trial (international)
- Endpoints: vaginal recurrence, recurrence-free survival, AE and
QOL, health costs
- Validation of molecular profile procedure in pathology centers -
> 3-4 in NL and in participating countries
- NCRI UK and ANZGOG planning to participate
