Here are a few studies I found. One is specific to monoclonal treatments, like Herceptin and Rituxan. There are 3 listed here. All of them are very early and small studies so we must use some caution in applying results to the entire population. The results in beta-glucan / anti-cancer research are impressive, however, and more research needs to be done in this area.
