CHAPTER 8 194 CONCLUSION A personalized risk stratification model including a combination of classic histomorphology, IHC markers, clinical markers and recently proposed molecular markers (Figure 4) appears to be the best approach in the diagnostic work-up of EC patients thereby reducing health costs. Thereafter, with the presented clinical decision tool an evidence based approach specific for primary and adjuvant treatment is proposed which may be tailored to the individual patient, giving her an optimal choice.

Combining histomorphology, IHC biomarkers, clinical markers and molecular biomarkers should be the best approach in the diagnostic work-up for EC patients.
