Abstract
Objective: To determine the usefulness of pelvic lymphadenectomy in the staging of ovarian dysgerminoma.
Method: Patients with a histopathological diagnosis of ovarian dysgerminoma who were staged between January 1995 and December 2013 were retrospectively studied.
Results: We found 39 cases, the mean age was 23.5 years. Histologically, 34 were pure dysgerminomas and 5 were mixed associated with endodermal sinus tumors. According to FIGO, we found stage IA in 15 patients, stage IB in 1 patient, stage IC in 8 patients, stage IIB in 1 patient, stage IIIA in 1 patient, and stage IIIC in 13 patients. Pelvic nodes with metastases were not documented in any of the patients studied.
Conclusions: The lymphatic spread pattern in ovarian dysgerminomas is always towards the retroperitoneal nodes, both paracaval and paraaortic, but there is no spread towards the pelvic lymph nodes. Therefore, we recommend not performing pelvic lymphadenectomy in surgical staging in these patients.
