ESMO 2013 is assigned using stage, grade, and histological subtype group into low, intermediate, and high risk based on the following criteria:

• low:

  • stage IA, grade 1/2, with endometrioid type

• intermediate:

  • stage IA, grade 3, with endometrioid type

  • stage IB, grade 1/2, with endometrioid type

• high:

  • all stages with non-endometrioid type
