Resumo: | Temozolamide (TMZ) is a new class of alkylating agents deriving from imidazotetrazine. TMZ is a substance of low molecular weight, and 100% of it is absorbed via the oral route; and it is eliminated by the body about 8 hours after intake. Due to the swift elimination ratio and to its action, TMZ presents decreased risk of being toxic to the marrow bone. On the other hand, being a lipophylic substance, TMZ crosses the blood-brain barrier and may reach brain tumors. This drug is active againt some solid tumors, and it has been studied for the treatment of highgrade gliomas, including anaplastic astrocytoma (AA), multiform glioblastoma (GBM), low-grade gliomas, and metastatic malignant melanoma (MM). This bibliography review made evident the lack of scientific grounds to allow TMZ to be a standard treatment for brain tumors or metastatic malignant melanoma. |

A TMZ é uma substância de baixo peso molecular, sendo 100% absorvida por via oral, e praticamente toda ela deverá ter sido eliminada após 8 horas da ingestão. Devido a esta rápida eliminação e ao seu mecanismo de ação, a TMZ tem risco reduzido de ser tóxica para a medula óssea. Por outro lado, em sendo uma substância lipofílica, a TMZ atravessa a barreira hemo-encefálica, o que a faz alcançar tumores cerebrais. Este medicamento apresenta atividade contra alguns tumores sólidos e tem sido investigada para tratamento de gliomas de alto grau, incluindo o Astrocitoma anaplásico (AA), o Glioblastoma multiforme (GBM), gliomas de baixo grau e o Melanoma maligno metastático (MM). Com a presente revisão bibliográfica, evidenciou-se ausência de bases técnicas e científicas que permitam considerar o TMZ um tratamento padrão dos tumores cerebrais ou do melanoma maligno metastático.INCA2002-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionRevisão de literaturaapplication/pdfhttps://rbc.inca.gov.br/index.php/revista/article/view/222010.32635/2176-9745.RBC.2002v48n3.2220Revista Brasileira de Cancerologia; Vol. 48 No. 3 (2002): July/Aug./Sept.; 439-445Revista Brasileira de Cancerologia; Vol. 48 Núm. 3 (2002): jul./ago./sept.; 439-445Revista Brasileira de Cancerologia; v. 48 n. 3 (2002): jul./ago./set.; 439-4452176-9745reponame:Revista Brasileira de Cancerologia (Online)instname:Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA)instacron:INCAporhttps://rbc.inca.gov.br/index.php/revista/article/view/2220/1381Najman, HenryGadelha, Maria Inez Pordeusinfo:eu-repo/semantics/openAccess2021-11-29T20:37:35Zoai:rbc.inca.gov.br:article/2220Revistahttps://rbc.inca.gov.br/index.php/revistaPUBhttps://rbc.inca.gov.br/index.php/revista/oairbc@inca.gov.br0034-71162176-9745opendoar:2021-11-29T20:37:35Revista Brasileira de Cancerologia (Online) - Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA)false |
