Liver Cancer

Nanba et al reported that 7 of 12 patients with liver cancer responded to a combination of Grifola frondosa fruiting body (4-6g/day) and purified polysaccharide extract (MD fraction – 40-150mg/day)1.

Studies using implanted sarcoma 180 as a model for liver cancer have shown rates of tumour inhibition of 52.8%, 56.6% and 51.9% when given polysaccharide extracts of Flammulina velutipes, Lentinula edodes and Agaricus subrufescens respectively2 and a 71.6% increase in lifespan of tumour-bearing mice with Polyporus umbellatus polysaccharide extract (i.p.) on its own and a 119.9% increase when given in conjunction with mitomycin C3.

Several in vitro studies using Ganoderma lucidum and G. lucidum triterpenes have demonstrated cell growth inhibition and anti-invasive effects by multiple mechanisms including suppression of protein kinase C, activation of protein kinases, G2-phase cell cycle arrest, inactivation of MAPK/ERK signal transduction pathway and inhibition of the binding activities of NF-kB and AP-14-9. In a human tumour xenograft model, a doseresponse inhibition was also observed in the average size, volume, and weight of tumours upon oral administration of G. lucidum extract10.

Antrodia camphorata has traditionally been used in the treatment of liver cancer in Taiwan. In vitro studies confirm its apoptotic effects on human liver cancer cell lines and a number of promising cases have been reported combining it with conventional treatment in cases of advanced liver cancer11,12.

Ophiocordyceps sinensis, Pleurotus ostreatus and Inonotus obliquus have all shown in vitro efficacy against liver cancer cell lines13-15.
