Study hypothesis
1. To determine the benefit or otherwise of lymphadenectomy in patients with endometrial cancer (thought pre-operatively to be confined to the corpus).
2. To determine the benefit or otherwise of post-operative adjuvant radiotherapy in patients with endometrial cancer, high risk pathology and no macroscopic disease following surgery

Eligibility
Participant inclusion criteria
Surgical randomisation inclusion:
1. Histologically proven diagnosis of endometrial carcinoma
2. Disease thought pre-operatively to be confined to the corpus (CT or MRI scanning suggesting node enlargement is not an exclusion to randomisation and should not influence the decision to randomise)
3. Patient fit to undergo lymphadenectomy
4. Centre able to offer appropriate surgery
5. Patient fit to receive external beam radiotherapy
6. Written informed consent (for randomisation into both surgical and radiotherapy components).
Radiotherapy randomisation inclusion:
1. Histologically proven diagnosis of endometrial carcinoma
2. Disease pre-operatively confined to the corpus
3. Macroscopically free of disease (positive para-aortic nodes should be viewed as indicative of further [unseen] macroscopic disease)
4. Fit to receive external beam radiotherapy
5. High risk pathology, assessed independently of nodal status, defined as one or more of the following: Grade 3 (poorly differentiated) or Invasion to the outer half of the myometrium or Serous papillary or clear cell type or Stage IIA
6. Written informed consent.
