Researchers traced genomic, epigenomic, and expression features in lung carcinoma in situ cases that regressed or progressed to invasive lung squamous cell carcinomas.
MSK researchers showed that high TMB may be associated with improved survival across tumor types, but the cut-offs for high and low status will vary based on histology.
The issue, discovered in late October, affected TMB reporting for up to 800 FoundationOne CDx tests during a short period of time and was quickly resolved.
The study authors cautioned that immunological signatures cannot be predicted from tumor mutational burden or microenvironment analysis of a single biopsy alone.
The study looked at chromatin accessibility in 410 TCGA tumors in the context of broader genomic features to explore functional effects of regulatory features.
A survey by Nature finds that most researchers want scientific meetings to continue virtually or with a virtual component, even after the pandemic ends.
Certain blood proteins may be able to distinguish COVID-19 patients who will become critically ill from those who will not, the Atlanta Journal-Constitution reports.
