Molecular integrated risk profile PORTEC-1/2 cohort

Stelloo et al, Clinical Cancer Research 2016

  • 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
  • Interested in participation? Please contact us!
