Stereotactic body radiotherapy is effective in modifying the tumor genome and tumor immune microenvironment in non-small cell lung cancer or lung metastatic carcinoma [exome-seq]
Background and purpose: To directly reveal the change in genome mutation, RNA transcript of tumor cells, and tumor microenvironment (TME) after stereotactic body radiotherapy (SBRT) in paired human lung tumor specimens. Overall design: Materials and methods: Paired tumor samples were collected from 10 patients with non-small cell lung cancer (NSCLC) or lung metastatic carcinoma within a week before and after SBRT. DNA and RNA of tumor tissues was extracted from the paired samples. Whole-exome and RNA sequencing assays were performed by next-generation sequencing. Gene mutation, genomic expression, T-cell receptor (TCR) repertoire, and profiling of tumor-infiltrating immune cells were analyzed through bioinformatics analysis in paired tumor samples. Case numbers are matched between the RNA-seq data set (GSE162945) and the exome-seq data set (this series). For example, case 2 in exome seq is from the same patient as case 2 in the RNA-seq study.
