ObjectiveThe aim of this study was to examine the outcomes in patients with high-risk Stage I endometrial cancers surgically staged by complete pelvic and para-aortic lymphadenectomy, with negative nodes, and treated with postoperative brachytherapy.MethodsFrom the database of patients treated for Stage I endometrial cancer, 23 patients were identified with either >50% myometrial invasion or grade 3 histology treated with total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic and para-aortic lymphadenectomy. All patients had no pathologic evidence of disease in the lymph nodes. These patients were then treated with brachytherapy and followed for treatment and cost outcomes. A comparison was made of the cost of treatment between brachytherapy and external beam radiation.ResultsAll 23 patients with either grade 3 tumor or greater than 50% myometrial invasion were treated with total abdominal hysterectomy with lymphadenectomy followed by brachytherapy for lesions that did not extend outside the uterine specimen. For all patients in this series, there were no recurrences in the follow-up period (median 25 months). This regimen is more cost efficient and spares the patient from possible complications related to whole pelvic radiation, at an average cost savings of $4100.ConclusionWomen undergoing hysterectomy for endometrial adenocarcinoma with high-risk node-negative disease confined to the uterus can be safely treated with brachytherapy, at a substantial cost savings, without compromising survival.Copyright 2001 Academic Press.
