REVIEW Lentinan is an anti-tumor polysaccharide isolated from the fruit body of the shiitake mushroom Lentinula edodes. It manifests marked antitumor and antimetastatic activity in numerous tumor/host systems, and prevents chemical and viral carcinogenesis. Modulation of immune or vascular functions is involved in its antitumor effects. Limited clinical studies of cancer patients have associated lentinan with a higher survival rate, higher quality of life, and lower re-occurrence of cancer.
