Table 4. Adjuvant therapy risk assessment.

Risk level	Radiotherapy	Chemotherapy
Low risk, n (%)	7 (17)	27 (64)
Intermediate risk, n (%)	11 (26)	NA
High risk, n (%)	24 (57)	15 (36)

NA.

For all tumours that are stage I, n = 42.

Radiotherapy risk assessment was assessed on the basis of zero risk factors (low), one risk factor (intermediate), or at least two (high) of the following risk factors: grade 3 endometrioid or non-endometrioid histotype; at least outer-half myometrial invasion; lymphovascular invasion.

Chemotherapy risk assessment was assessed on the basis of one (low) or two (high) of the following risk factors: grade 3 endometrioid or non-endometrioid histotype; at least deep myometrial invasion.
