Abstract
OBJECTIVES: To demonstrate the therapeutic potential of the laterally extended endopelvic resection (LEER) especially for patients with recurrent cervical carcinomas involving the side wall of an irradiated pelvis. These patients, suffering from the most common situation of local failure, have so far no longer been considered for curative therapy. METHODS: Extending the lateral resection plane of pelvic exenteration to the medial aspects of the lumbosacral plexus, sacrospinous ligament, acetabulum, and obturator membrane enables the complete removal of a subset of locally advanced and recurrent tumors of the lower female genital tract fixed to the pelvic wall with free margins (R0). Patients selected for LEER were accrued to a prospective outcome trial. RESULTS: Thirty-six patients with recurrent (n = 29) or primary advanced (n = 7) gynecologic malignancies involving the side wall of the lesser pelvis underwent LEER from July 1996 until October 2002. The majority of the patients suffered from cervical carcinoma (n = 29) and had received previous pelvic irradiation (n = 24). Tumor-free (R0) lateral margins were obtained in 34 patients. Severe postoperative complications occurred in 14 patients with one treatment-related death. Five-year survival probability is 49% for the whole group and 46% for those patients considered only for palliation with current treatment options. Most patients without evidence of disease at least 1 year after LEER achieved good quality of life. CONCLUSIONS: LEER can be offered as novel surgical salvage therapy to a selected subset of patients with locally advanced and recurrent cervical carcinoma involving the pelvic wall.
