Robotic Radical Parametrectomy With Upper Vaginectomy and Pelvic Lymphadenectomy in Patients With Occult Cervical Carcinoma After Extrafascial Hysterectomy

Abstract

Study ObjectiveTo confirm the safety and feasibility outcomes of robotic radical parametrectomy and pelvic lymphadenectomy and compare the clinicopathological features of women requiring adjuvant treatment with the historical literature. DesignRetrospective cohort study and review of literature (Canadian Task Force classification II-2). SettingDepartment of Obstetrics and Gynecology, University of North Carolina at Chapel Hill. PatientsAll patients who underwent robotic radical parametrectomy with upper vaginectomy (RRPV), and pelvic lymphadenectomy for occult cervical cancer discovered after an extrafascial hysterectomy at our institution between January 2007 and December 2015. InterventionsRRPV and pelvic lymphadenectomy for occult cervical cancer discovered after an extrafascial hysterectomy. We also performed a literature review of the literature on radical parametrectomy after occult cervical carcinoma. Measurements and Main ResultsSeventeen patients with invasive carcinoma of the cervix discovered after extrafascial hysterectomy underwent RRPV with bilateral pelvic lymphadenectomy. There were 2 intraoperative complications, including 1 bowel injury and 1 bladder injury. One patient required a blood transfusion of 2 units. Three patients underwent adjuvant treatment with chemoradiation with radiation-sensitizing cisplatin. One of these patients had residual carcinoma on the upper vagina, 1 patient had positive parametria and pelvic nodes, and 1 patient had positive pelvic lymph nodes. No patients experienced recurrence, and 1 patient died from unknown causes at 59.4 months after surgery. We analyzed 15 studies reported in the literature and found 238 women who underwent radical parametrectomy; however, no specific preoperative pathological features predicted outcomes, the need for adjuvant treatment, or parametrial involvement. ConclusionRRPV is a feasible and safe treatment option. As reflected in the literature, RRPV can help avoid empiric adjuvant chemoradiation; however, no pathological features predict the need for adjuvant treatment after surgery.
