ABSTRACT

Objective:

In addition to the well-established pathophysiological role that COX-2 plays in inflammation, recent evidence implies that this isoform may also be involved in multiple biologic events throughout the tumorigenic process. Many epidemiological studies demonstrate that nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the risk of a wide range of tumors. Further, COX-2 is chronically over expressed in many premalignant, malignant, and metastatic human cancers, and levels of over expression have been shown to significantly correlate to invasiveness, prognosis, and survival in some cancers.

Conclusions:

This article presents a broad overview of the growing evidence that COX-2 plays a pivotal role throughout oncogenesis and summarizes the rationale to explore the use of COX-2 inhibitors for the prevention or treatment of cancer as a single agent or in combination with current anticancer modalities. Epidemiological data and preclinical studies have generated compelling interest in the potential use of COX-2 inhibitors in chemoprevention and chemotherapy of human tumours.
RESUMO

Objetivos:

Além do papel fisiopatológico bem definido que a COX-2 desempenha na inflamação, a evidênciarecente sugere que essa isoforma também pode estar envolvida em eventos biológicos múltiplos durante oprocesso de tumorigênese. Vários estudos epidemiológicos demonstram que anti-inflamatórios não esteroides (AINEs) reduzem o risco de uma grande variedade de tumores. Além disso, sabe-se que há sobre-expressãocrônica da COX-2 em muitos tumores humanos pré-malignos, malignos e metastáticos, tendo sido demonstradacorrelação dessa sobre-expressão com a invasão, o prognóstico e a sobrevida de alguns tumores.

Conclusões:

Este artigo apresenta uma visão ampla da crescente evidência de que a COX-2 desempenha papel fundamentalna oncogênese e resume os fundamentos para explorar o uso de inibidores COX-2 para a prevenção ou o tratamentodo câncer como um único agente ou em combinação com atuais modalidades anticancerígenas. Dadosepidemiológicos e estudos pré-clínicos têm gerado grande interesse no uso potencial de inibidores COX-2 naquimioprofilaxia e quimioterapia de tumores humanos.
