[Successful chemotherapy and concurrent radiotherapy for metastatic lung. mediastinal malignant fibrous histiocytoma].

We treated a patient for malignant fibrous histiocytoma (MFH) which metastasized to mediastine and lung from left femur. The patient was a sixty-three year old man. He had his left femur, the primary lesion, resected. After the first operation, we found metastasis to his lung and mediastine and we performed twice thoracotomy. Then he was found to have the third metastasis which we decided was inoperable, this time we tried chemotherapy and concurrent radiotherapy. CDDDP and ACR with radiotherapy showed significant effect. The patient died after eight months at last because of fistula between the descending aorta and the ileum, and as we performed an autopsy on him, his MFH proved pathological CR.
