[Transarterial Chemoembolization for Liver Metastasis of Ovarian Malignant Melanoma Resulting in Long-Term Survival].

: Melanoma is a potentially aggressive disease, and patients with metastatic melanoma have a poor prognosis, with a median survival of only 6-9 months. There is no effective standard treatment for liver metastasis of malignant melanoma. Primary ovarian malignant melanoma is extremely rare and is usually associated with teratoma. We report a case of malignant melanoma arising in a mature ovarian cystic teratoma that had metastasized to the liver. Six courses of systemic chemotherapy were administered. However, as the liver metastases became enlarged, we performed transarterial chemoembolization(TACE). Following repeated TACE using drug-eluting microspheres for the liver metastasis, the patient survived 80 months from the initial diagnosis.
