To test the relationship between PSGs and tumor immune response, principal component analysis (PCA) was conducted on 22 immune cell types in CIBERSORT, and a model was developed for the female group in the TCGA, using three principal components (PCs) derived from CIBERSORT together with PSG genes and their related genes, which provided little improvement (CPTAC validation C-index = 0.71) in predictive performance. Here, PSG5 is linked to neoplasm.
