Cancer field surgery to salvage patients with locally advanced and recurrent cervicovaginal and endometrial carcinomas not suitable for radiotherapy, termed laterally extended endopelvic resection (LEER), is described. Lymph node dissection comprises the complete removal of first-, second-, and third-line lymph node regions related to the Müllerian compartment. Reconstructive procedures, except for urinary diversion, are outlined. Recommendations for the pre- and postoperative management of these complex procedures are presented as well. Complications are frequent and demand particular consideration using a multidisciplinary approach.
