Definitions
- the present invention relates to an anti-malignant glioma agent and an animal anti-malignant glioma agent.
- a tumor is a group of cells showing autonomous hyperproliferation, and is classified into a malignant tumor (so-called cancer) that may cause the tumor-bearing animal to die, and a benign tumor that does not. There are many exceptions and it is difficult to make a strict distinction (Iwanami Biological Dictionary, 3rd edition, p. 4).
- Primary brain tumors are classified into more than ten groups, such as gliomas and meningiomas, according to their origin or histopathological type. Among them, neurogliomas are the most important in both frequency and malignancy, and gliomas are classified into seven or more types, such as glioblastomas and malignant astrocytomas, according to the detailed histopathology. You. For the grade of primary brain tumor, in addition to the stage (tumor size, presence or absence of distant metastasis), histological grade is used. Histological grades are classified into four stages from G1 to G4 according to the Brain Tumor Handling Rules (ibid.), And correspond to WHO 1 to WHO 4, respectively.
- the grade of glioblastoma is G4 (WHO 4)
- the grade of malignant astrocytoma is G3 (WHO 3)
- G3 and G4 are classified as malignant. Therefore, the primary brain tumor to be targeted primarily by the anti-brain tumor agent is a glioma, particularly a high-grade glioblastoma or malignant astrocytoma.
- Glioma is a tumor that develops in the brain parenchyma and proliferates invasively, and it is difficult to cure it only by surgery. Glioblastoma is the most resistant to treatment, with a very poor 5-year survival rate of around 8%.
- the only chemotherapeutic agents for which the efficacy was clearly confirmed were only alkylidani and temozolomide, which also remained in combination with radiation therapy. On the other hand, postoperative radiation has been shown to have a prolonged survival effect.
- TNF-a has a certain antitumor effect on brain tumors when used in a special way. For example, an antitumor effect was obtained when glioblastoma was locally injected with TNF- ⁇ (Non-Patent Document 1), and a certain antitumor effect was obtained by injecting TNF-a into arteries ( Non-patent document 2) has been reported.
- TNF-a when administered, there is a problem that even if an anti-tumor effect is obtained, it does not lead to a prolonged life effect. There are no reports of prolonged life. No survival benefit was observed in glioblastoma rats to which TNF- ⁇ was administered.
