Abstract

Objective

To analyze the role of surgery alone, including pelvic and para-aortic lymphadenectomy, in patients with endometrial cancer who did not receive radiotherapy.

Methods

Between August 1987 and January 1997, 225 women with disease clinically confined to the uterus were staged surgically by a standard protocol that included pelvic and para-aortic lymphadenectomy in women with high risk factors. No radiation was administered before or after surgery.

Results

The combination of preoperative endometrial biopsy grade and gross depth of myometrial invasion identified 123 (55%) high-risk patients who had lymphadenectomy and 102 (45%) low-risk patients who did not. Eighteen (15%) high-risk patients had lymph node metastases and received postoperative systemic therapy. Three low-risk, eight high-risk-node-negative, and no high-risk-node-positive patients were diagnosed with recurrent cancer, corresponding to 5-year recurrence-free proportions of 0.95, 0.89 and 1.00, respectively. Although sample sizes and limited follow-up limit conclusions, the experience to date suggests a high rate of survival in all three groups.

Conclusion

Our preliminary experience indicates that even high-risk patients have an excellent prognosis when treated with surgery, including pelvic and para-aortic lymphadenectomy, without radiotherapy.
