Exploration of the effect and mechanism of activating blood circulation and stasis-removing therapy on tumor metastasis.

Metastasis is one of the specificities of late stage tumor and also a lethal factor often encountered. The study of tumor metastasis has important meaning for prolonging patients' survival and elevating their quality of life, but no really ideal prevention and treatment method has been found so far. Recent researches showed that tumor metastasis is correlated with platelet aggregation and blood hyperviscosity manner. Therefore, the early application of surgery, radiotherapy, chemotherapy and biological therapies, in combination with Chinese medicine therapy for activating blood circulation and removing stasis (ABCRS) may be, after all, an effective approach. ABCRS therapy is an important therapy of Chinese medicine, which, composed of several methods like smoothening blood flow in vessels, promoting blood circulation and dispersing stagnant blood, could influence tumor metastasis to different extents, and could coordinate with some other Chinese medicine therapeutic methods like supplementing qi, promoting qi, clearing heat, removing toxic substances, warming meridian, dispelling wind, eliminating dampness, nourishing yin, dissolving sputum, relieving stagnancy, emptying viscerals, etc. The effect and acting mechanism of ABCRS on tumor metastasis is summarized in this paper and its bi-directional regulatory effects discussed as well.
