Recent studies are exploring the potential health benefits of various mushroom compounds, with a spotlight on the commonly consumed white button mushroom. While mushrooms are often celebrated for their culinary uses, emerging research suggests that they could also play a critical role in cancer treatment.

A team of researchers from the City of Hope Comprehensive Cancer Center in Duarte, California, investigated the effects of white button mushroom extract on prostate cancer progression in both mice and human patients. Their findings, published in the journal Clinical and Translational Medicine, suggest that this mushroom extract could enhance the efficacy of immunotherapy treatments.

The researchers observed a notable reduction in specific immune-suppressing cells, known as myeloid-derived suppressor cells (MDSCs), within tumors after administering the extract. Simultaneously, they documented an increase in various immune cells, including T cells and natural killer cells, both vital for combating cancer. This shift in immune dynamics indicates a potential mechanism whereby white button mushroom extract assists the immune system in identifying and destroying cancerous cells.

The polysaccharides present in white button mushrooms, particularly β-glucan, were highlighted as key components responsible for these effects. These compounds have been previously linked to immune enhancement in other studies. As a result, researchers hypothesize that the extract may not only slow tumor growth but also work synergistically with existing immunotherapy drugs.

Dr. Frédéric A. Meunier, a distinguished researcher at the University of Queensland who did not participate in the study, described the findings as "impressive". He noted the comprehensive nature of the research, which transitioned from animal models to human clinical trials, suggesting significant potential for a nutraceutical approach to delay prostate cancer progression.

Interestingly, earlier research has demonstrated the beneficial effects of white button mushroom extracts in patients undergoing prostate cancer treatment. Blood samples from patients revealed a decrease in MDSCs and a rise in cancer-fighting T cells after three months of consuming the extract.

In their animal studies, the researchers administered white button mushroom extract alongside anti-PD-1 antibodies to evaluate the combined effect on tumor growth. Results showed that mice treated with both therapies experienced enhanced tumor suppression and lived an average of eight days longer than those receiving immunotherapy alone.

While these findings are promising, the researchers advise caution. Dr. Xiaoqiang Wang, the study’s lead author, emphasized the importance of professional medical consultation before incorporating mushroom supplements into one’s diet, especially as many products available online are not FDA-approved. Nonetheless, he suggests that including more fresh white button mushrooms in one's daily meals could be beneficial.

This growing body of research positions white button mushrooms as a potential ally in the fight against prostate cancer. Further investigations will be crucial to unravel the mechanisms behind their effects and identify the specific polysaccharides involved. As studies continue, the future of mushroom-based supplements in cancer therapy looks increasingly hopeful.
