This study analyzed deep DNA sequence data from 1870 patients with myeloid malignancies and found evidence of dysbiosis in disease cases, as well as distinct microbial signatures among disease subtypes. It also highlighted the association between microbial content and host gene mutations and myeloblast cell percentages. The study provided evidence that Epstein-Barr virus status refines risk stratification in low-risk myelodysplastic syndrome patients and constructed machine-learning classifiers to discriminate among disease subtypes based solely on bacterial content.
Although recent work has described the microbiome in solid tumors, microbial content in hematological malignancies is not well-characterized. Here we analyze existing deep DNA sequence data from the blood and bone marrow of 1870 patients with myeloid malignancies, along with healthy controls, for bacterial, fungal, and viral content. After strict quality filtering, we find evidence for dysbiosis in disease cases, and distinct microbial signatures among disease subtypes. We also find that microbial content is associated with host gene mutations and with myeloblast cell percentages. In patients with low-risk myelodysplastic syndrome, we provide evidence that Epstein-Barr virus status refines risk stratification into more precise categories than the current standard. Motivated by these observations, we construct machine-learning classifiers that can discriminate among disease subtypes based solely on bacterial content. Our study highlights the association between the circulating microbiome and patient outcome, and its relationship with disease subtype.
