Mapping the pancancer metastasis tumor microbiome

Abstract

The landscape of the intratumoral microbiome in tumor metastases is largely unchartered. In this issue of Cell, Voest et al. profiled the tumor metastasis-associated microbiome in a pancancer cohort of 4,160 biopsies from 26 cancer types. This dataset offers a useful resource for understanding the role of the microbiome in metastatic cancers.
