Pan-cancer analyses reveal cancer type-specific fungal ecologies and bacteriome Interactions [Cell, 2022]

In this work, we explored the presence of intra-tumor fungi – the tumor mycobiome. In collaboration with the Knight lab, we looked into the presence of fungi in 35 tumor types and over 17,000 human samples. Fungi were detected in all of these tumor types and demonstrated tumor-type specific signatures. Similar to bacteria, fungi were visualized in both cancer and immune cells. We found interesting fungal-bacterial-immune cell associations. In addition, we found specific fungi associated with different clinical outcomes, such as response to immunotherapy and overall survival. Lastly, we found that fungal DNA within the plasma of individuals could be used to discriminate between healthy individuals and cancer patients.
