AbstractNewer treatments of advanced human cancer are based on combination of cancer drugs that have different mechanism of actions yet the combination strategy may potentiate the anti-cancer effects and cytotoxicity. Recent studies suggest that cancer growth can be inhibited more effectively by combination of phytochemicals that affect different pathways. The apoptotic activity can be modulated by intrinsic and extrinsic molecules. The combination of anti-tumor phytochemicals can be more effective in modulating different signaling pathways associated with tumor cell growth which is the common target for anti-tumor action. Combinations of cytotoxic anti-tumor agents and inhibitors from phytochemicals are believed to act together producing inhibitory mechanisms on cancer growth. This combination strategy shows promise on cancer therapy. However, the combination of phytochemicals in cancer therapy needs to be further investigated to develop a better treatment strategy. Recent patents on anti-tumor phytochemicals are reviewed in this article.
