Early stage endometrial carcinoma--a study of management and outcome.

The surgical management of early stage endometrial carcinoma is controversial. The benefits of pelvic lymphadenectomy and administration of radiotherapy in this group have been disputed. We aimed to document the experience of stage 1 endometrial carcinoma at the National Maternity Hospital during the 10 year period 1989-1998 and to evaluate and compare clinical outcomes between retrospectively-assigned low and high-risk tumour groups. Seventy seven women were diagnosed with Stage 1 endometrial carcinoma in this period. Thirty-nine women had low-risk and 38 had high-risk tumours. Women with high-risk tumours were older and had a higher rate of lymph-vascular space invasion by tumour on histological examination. Three women (3.9%) developed disease recurrence and died of their disease; one low-risk and two high-risk tumour patients. Survival without recurrence did not differ between the two risk groups. No consistent pattern existed in surgical staging between the two risk groups. A prospectively-assigned definition of risk would minimise variations in clinical practice by providing a basis for a more tailored approach to adjuvant treatments.
