Cancer chemoprevention: current state of the art

Area of Science:

• Oncology
• Molecular Biology
• Pharmacology

Background:

• Cancer chemoprevention aims to disrupt or delay molecular pathways crucial to carcinogenesis.
• Key molecular mechanisms include DNA damage, NF-κB signaling, epigenomic deregulation, and epithelial-mesenchymal transition.
• Dietary phytochemicals and synthetic compounds show promise in inhibiting these early carcinogenic events.

Purpose of the Study:

• To review the role of chemopreventive compounds in inhibiting cancer initiation.
• To examine the ability of these compounds to reduce cancer progression and metastasis.

Main Methods:

• Review of scientific literature on cancer chemoprevention.
• Analysis of molecular mechanisms targeted by chemopreventive agents.
• Evaluation of dietary phytochemicals and synthetic compounds for chemopreventive potential.

Main Results:

• Dietary phytochemicals can inhibit the initiation phase of carcinogenesis.
• Phytochemicals and synthetic compounds interfere with molecular mechanisms of metastasis.
• Chemoprevention offers a strategy to prevent cancer development, improving patient outcomes.

Conclusions:

• Chemopreventive agents, including phytochemicals and synthetic compounds, are vital for disrupting carcinogenesis.
• Early intervention through chemoprevention can significantly reduce cancer initiation and progression.
• Preventing cancer development through chemoprevention is a superior strategy to managing established disease.
