Primary gingival angiosarcoma successfully treated by radiotherapy with concurrent intra-arterial chemotherapy

摘要

The occurrence of angiosarcoma in the oral cavity is extremely rare, and optimal management of this tumor is undefined. These tumors are aggressive, with a high propensity for local recurrence. We present here a case of primary gingival angiosarcoma successfully treated by intra-arterial chemotherapy concurrent with radiation therapy. A 69-year-old female with a primary angiosarcoma in the right maxillary gingiva was admitted to our hospital. The diagnosis of angiosarcoma was established by immunohistochemistry. The patient refused surgical treatment, and so intra-arterial cisplatin and concurrent radiation were given. The gingival tumor disappeared after completion of the therapeutic regimen. However, the patient died 8 months after initial treatment because of multiple lung metastases. Locoregional control was achieved up to her death. To our knowledge, this is the first report of this treatment for angiosarcoma of the oral cavity.
