  • Publication number: 20020176898
    Abstract: The invention described herein encompasses a methods and compositions of treating cancer or solid tumors comprising the administration of a therapeutically effective amount of catechins, a group of polyphenols found in green tea, to a mammal in need of such therapy. Compositions of catechins include but not limited to, epigallocatechin gallate (EGCg), epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC). The unique compositions of the invention contain various combinations of the catechins, alone or in combination with each other or other therapeutic agents and are used to treat primary and metastatic cancers in humans. The invention also encompasses the varying modes of administration of the therapeutic compounds, including a sustained release formulation which may be used as a therapeutic compound for the treatment of cancer or as a dietary supplement for the prevention of cancer.
