ZALTOPROFEN POUR PRÉVENIR LA FORMATION DE MÉTASTASES D'UNE TUMEUR À CELLULES GÉANTES QUI APPARAÎT DANS DES PARTIES OSSEUSES OU MOLLES, DE MÉTASTASES D'UN CHONDROSARCOME OU DE MÉTASTASES D'UN OSTÉOSARCOME
The present invention provides an agent for prophylactic treatment, therapeutic treatment, or prevention of metastasis of giant cell tumor occurring in a bone and soft tissue, chondrosarcoma, or bone sarcoma, a local infusion for artery embolization, and an artificial bone, which comprises a substance having a PPAR³-agonistic activity and/or a PPAR³ expression-inducing activity as an active ingredient. The agent for prophylactic treatment, therapeutic treatment, or prevention of metastasis, the local infusion for artery embolization, and the artificial bone of the present invention are a radical therapeutic agent or radical therapeutic material that can cause apoptosis in giant cell tumor occurring in a bone and soft tissue, chondrosarcoma, or bone sarcoma to make the tumor disappear, and can induce differentiation of the tumor into fat cells to make the tumor disappear.
