Lymphadenectomy in high risk endometrial carcinoma stage I and II: no more morbidity and no need for external pelvic radiation.

Abstract

The objectives of this retrospective study were to analyze the morbidity of surgical staging and to evaluate the omission of external radiotherapy in high-risk patients with stage I and II endometrial carcinoma when the lymph nodes were negative. From 1988 to 1996, 63 of 117 patients underwent a pelvic and periaortic lymphadenectomy. The decision to perform lymphadenectomy was influenced by patient general health. Patients with lymphadenectomy had a better physical status (P < 0.0001). Lymphadenectomy increased mean operative time (P < 0.0001) and blood loss (P < 0.01), but there was no increase in postoperative complications. At a median follow-up of 54 months, there was one cuff recurrence in 56 patients. Nineteen high-risk patients without external pelvic radiation had the same disease-free survival rate as 37 low-risk patients (P = 0.1). In the group without lymphadenectomy, the disease-free survival for 18 high-risk patients and 32 low-risk patients was similar (P = 0.21). Surgical staging in properly selected patients does not increase postoperative complications and brachytherapy without external radiotherapy is associated with excellent disease-free survival when the lymph nodes are negative.
