# Kassandra: Cell Deconvolution Tool from RNA-seq

*Precise reconstruction of the tumor microenvironment using bulk RNA-seq and a unique machine learning-based algorithm trained on artificial transcriptomes*

Here, we present Kassandra, a robust and accurate cell deconvolution tool developed for analysis of healthy tissue and tumor biopsies. Based on RNA-seq NGS data of a biological sample, Kassandra predicts cellular composition including stromal and immune elements by analyzing the gene expression. This will lead to an improved understanding of the tumor microenvironment, which is a critical factor in cancer pathogenesis, clinical outcome, and therapeutic resistance.

Kassandra is a decision tree machine learning-algorithm trained on a collection of over thousands of RNA profiles from various sorted cell types. Performance was validated on over 4,000 H&E tissue slides and more than 1,000 samples comprising normal and tumor tissues by comparison with cytometric, immunohistochemical or single-cell RNA sequencing measurements of the same tissue.
