Can we omit para-aorta lymph node dissection in endometrial cancer?
GROUND: Patients with endometrial cancer can present with various complicating illnesses, including obesity, diabetes mellitus, hypertension and advanced aging. These patients are at high risk of severe post-operative complications. Thus, the question of whether or not to perform systemic pelvic and para-aortic lymphadenectomy remains controversial for all patients. It is reported that external iliac lymph nodes are the most commonly involved lymph nodes in endometrial cancer, and para-aortic lymph node (PAN) metastases spread via a route shared by the common iliac lymph nodes. The aim of this study was to evaluate the potential efficacy of omitting PAN dissection when metastasis of the common iliac and external iliac lymph nodes is negative. METHODS: Between January 1994 and June 2004, a total of 101 patients at Akita University Hospital who had undergone total hysterectomy and bilateral salpingo-oophorectomy, total pelvic lymphadenectomy and para-aortic lymphadenectomy to the level o
