[Successful treatment with administration of systemic high dose methotrexate and intraarterial carboplatin for osteosarcoma of the skull: a case report].
An 11-year-old boy was admitted with a painless lump in the right frontal area as his chief complaint. On admission, physical and neurological examinations were normal except for the localized lump constituting the frontal lesion. Skull roentgenogram showed an osteoblastic and osteolytic mass with radiating bony spicules "sunray appearance" around the coronal suture. CT scans demonstrated it more clearly. The initial surgery was performed in July 1993. Pathological specimen showed osteosarcoma of the skull. The patient was transferred to our hospital for chemotherapy. The regimen consisted of intravenous high dose methotrexate 9,000 mg given for 6 hours with leucovorin rescue in a single course. Following 4 courses of high dose methotrexate, he underwent residual tumor resection. Two courses of intraarterial carboplatin 150 mg and methotrexate 200 mg were also given. Histologically, the lesion showed complete remission of the tumor, and no viable tumor cells were seen. Two additional courses of high dose methotrexate were given. The patient is doing well without evidence of recurrence. This case indicates that the chemotherapy with systemic high dose methotrexate and intraarterial carboplatin and methotrexate is effective for skull osteosarcoma.
