Effect of cryoablation on the spatial transcriptomic landscape of the immune microenvironment in non-small cell lung cancer

Abstract

Background: Cryoablation induces antitumor immune responses. Spatial transcriptomic landscape technology has been used to determine the micron-level panoramic transcriptomics of tissue slices in situ.

Methods: The effects of cryoablation on the immune microenvironment in non-small cell lung cancer (NSCLC) were explored by comparing the Whole Transcriptome Atlas (WTA) panel of immune cells before and after cryoablation using the spatial transcriptomic landscape.

Results: The bioinformatics analysis showed that cryoablation significantly affected the WTA of immune cells, particularly genes related to cellular components, biological processes, molecular functions, proliferation and migration, and cytokine-cytokine receptor interaction signaling pathways.

Conclusions: The findings of this study suggest that cryoablation significantly impacts the biological functions of immune cells in the tumor microenvironment of NSCLC through multiple mechanisms.
