Metastasis of ovarian dysgerminoma in a postmenopausal patient: a rare case report

Ovary dysgerminoma is one of the most good prognosis malignant tumor, which has a 5-year overall survival rate exceeding to 90%. Generally, the incidence of ovarian dysgerminoma (OD) is relatively low, accounting for ~0.6% of all ovarian tumors. Usually, it mainly occurs in very young women, about 85% of patients under 30 years old and is rare in middle-aged especially in elderly ones. This ovary dysgerminoma case report presents a 58-year-old menopausal postmenopausal woman which has a poor prognosis. Therefore, there may be differences between the elderly and young women in clinical characteristic that require separate management. This case reports a postmenopausal woman who was diagnosed with ovary dysgerminoma. After surgery, the patient was treated chemotherapy with bleomycin, etoposide, and cisplatin (BEP) according to the treatment guidelines. Unusually, the patient developed bone marrow suppression and lymph node metastasis in final. This report explored the clinical characteristic in postmenopausal woman dysgerminoma. Changes in lactate dehydrogenase (LDH) throughout the course of the disease are closely related to the progression. The patient had a disease progression when treated with the conventional treatment (BEP). The applicability of this treatment protocol to postmenopausal patients requires further research. Postmenopausal woman dysgerminoma is rare but rapid progress. Whether BEP is suitable for OD in middle-aged and elderly people remains to be further validated in the future. LDH may be a potential biomarker for monitoring the progression of OD in the elderly.
