Abstract
Purpose: The aim of this study is to evaluate the oncologic outcome in patients with pure ovarian dysgerminomas treated and followed-up in our hospital. Methods: This study included 18 ovarian dysgerminoma patients with unilateral and/or bilateral salpingo-oophorectomy (BSO) ± hysterectomy+omentectomy+bilateral pelvic ± para-aortic lymphadenectomy+peritoneal cytologic sampling. Results: Four (22%) patients underwent definitive surgery, including type I hysterectomy and BSO. Only one of the remaining 14 patients underwent BSO because of bilateral streak gonad presence during intraoperative examination. Thirteen patients (72%) had conservative surgeries. In addition, staging surgeries were performed to all patients except for one patient with 16 weeks of pregnancy (patient #3) in the study group. Retroperitoneal lymphadenectomy was part of the staging procedure except for this pregnant patient. Lymph node metastasis was positive in four (22%) patients. Three (16%) patients recurred and none of them died because of disease during follow-up period. Two of the relapsed patients were treated with combination of surgery and chemotherapy, whereas the third patient received only chemotherapy for treatment. Conclusions: Fertility sparing surgery should be the choice of treatment in patients with pure ovarian dysgerminoma. In addition, staging surgery, including retroperitoneal lymph node dissection is obligatory for determining stage IA patients who are exempt from adjuvant chemotherapy. Close surveillance policy enables early detection of patients with recurrences in whom salvage therapy is highly curable.
