Maitake mushroom md fraction

Here is a link to some interesting research on the use of Maitake mushroom D (sorry, not MD as in the my title post) extract on human cancer patients.  The numbers of patients involved were small, but the results do show some promise.  They show the results of both chemotherapy and combined chemo with maitake extact on various cancers in patients.   Breast cancer was among the types of cancers that showed a positive response to the treatment.

Here is the conclusion of the study:

 Since the cultivation method of Maitake mushroom was established in mid 1980's, this legendary and delicious mushroom has gained much popularity among Japanese people. Anecdotes and folklore on its medicinal values have also been elucidated by a number of mycologists and pharmacologists and its strong anti-tumor activity has attracted many researchers. It should be noted that, unlike many other mushroom extracts that have to be injected intravenously, Maitake D-fraction has a strong ability to inhibit tumor growth when given orally as well. In this context, various tests were conducted focusing on inhibition of growth and metastasis of cancer after surgery, by oral administration of Maitake. Even though this was a limited and non-controlled trial, the clinical study indicated that Maitake D-fraction is effective against such cancers of the breast, lung, liver, prostate and brain. Both human and animal tests demonstrate a synergistic effect with chemotherapy while ameliorating severe side effects from chemotherapy. Though the data is preliminary, the results of animal (and limited clinical ) studies based on Maitake D-fraction suggest significant healing and preventing potential for cancers and other immune-related health disorders. It is important to note that even among Maitake Mushrooms (Grifolafrondosa),there are many strains and some contain very little Beta-glucan,the active ingredient to stimulate the immune system. From such strains of Maitake, D-fraction may not be obtained.

 I'd say its important to read the study yourself,and recognize the limitations, as some of it is animal studies, and the human studies were small in number, but impressive nevertheless.

Anyone find any more studies conducted to further this research from 10 years ago?
