Résumé

To evaluate the characteristics of the tumor immune-microenvironment in brain metastases of non-small-cell lung cancer (NSCLC), we investigated the immunophenotype of primary NSCLC and its brain metastasis. Expression profiling of 770 immune-related genes in 28 tissues from primary and brain metastases of NSCLC was performed using the NanoString nCounter PanCancer Immune Profiling Panel. The immune cell profiles were validated by immunohistochemistry of 42 matched samples. Based on unsupervised clustering and principal component analysis of the immune-related gene expression profile, tumors were primarily clustered according to the involved organ and further grouped according to the EGFR mutation status. Fifty-four genes were significantly differentially expressed between primary and brain metastatic tumors. Clustering using these genes showed that tumors harboring mutated EGFR tended to be grouped together in the brain. Pathway analysis revealed that various immune-related functions involving immune regulation, T cell activity, and chemokines were enriched in primary tumors compared to brain metastases. Diverse immune-related pathways were upregulated in brain metastases of EGFR-mutated compared to EGFR-wild-type adenocarcinoma, but not in primary tumors. The interferon-γ-related gene signature was significantly decreased in brain metastases. The anti-inflammatory markers TOLLIP and HLA-G were upregulated in brain metastases. The proportions of most immune cell subsets were decreased in brain metastases, but those of macrophages and CD56dim-NK-cells were increased, as was the ratios of CD163 Our findings illustrate the immune landscape of brain metastases from NSCLC and reveal potential therapeutic strategies targeting cellular and non-cellular components of the tumor immune-microenvironment.

BACKGROUND BACKGROUND
To evaluate the characteristics of the tumor immune-microenvironment in brain metastases of non-small-cell lung cancer (NSCLC), we investigated the immunophenotype of primary NSCLC and its brain metastasis.
METHODS METHODS
Expression profiling of 770 immune-related genes in 28 tissues from primary and brain metastases of NSCLC was performed using the NanoString nCounter PanCancer Immune Profiling Panel. The immune cell profiles were validated by immunohistochemistry of 42 matched samples.
RESULTS RESULTS
Based on unsupervised clustering and principal component analysis of the immune-related gene expression profile, tumors were primarily clustered according to the involved organ and further grouped according to the EGFR mutation status. Fifty-four genes were significantly differentially expressed between primary and brain metastatic tumors. Clustering using these genes showed that tumors harboring mutated EGFR tended to be grouped together in the brain. Pathway analysis revealed that various immune-related functions involving immune regulation, T cell activity, and chemokines were enriched in primary tumors compared to brain metastases. Diverse immune-related pathways were upregulated in brain metastases of EGFR-mutated compared to EGFR-wild-type adenocarcinoma, but not in primary tumors. The interferon-γ-related gene signature was significantly decreased in brain metastases. The anti-inflammatory markers TOLLIP and HLA-G were upregulated in brain metastases. The proportions of most immune cell subsets were decreased in brain metastases, but those of macrophages and CD56dim-NK-cells were increased, as was the ratios of CD163
CONCLUSIONS CONCLUSIONS
Our findings illustrate the immune landscape of brain metastases from NSCLC and reveal potential therapeutic strategies targeting cellular and non-cellular components of the tumor immune-microenvironment.
