Lung Cancer

Trametes versicolor polysaccharide extracts show impressive benefits in cases of lung cancer.

In a 1993 study on patients with stage I-III non-small cell lung cancer treated with radiotherapy and PSK, PSK extended 5-yr survival 2-4x for all stages with maximum benefit in patients over the age of 70 and for tumours less than 5cm in diameter. In a 2003 study with non-small-cell lung cancer patients post-radiotherapy, those patients who received 3g PSK daily in 2 week cycles (2 weeks on, 2 weeks off) were almost 4 times more likely to be alive after 5 years than those without PSK (27% vs. 7%), with stage III patients who received PSK having a better prognosis than stage I/II patients who did not1.

Grifola frondosa polysaccharide extract/fruiting body combination has also been reported to produce improvement in 65% of lung cancer patients.2.
