RESUMEN
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.
