To predict the immunotherapy sensitivity, the Immunophenoscore (IPS) was calculated using the Cancer Immunome Atlas (https://tcia.at/). The IC50 of common chemotherapeutic drugs was counted in the training group via the administered “pRRophetic” package to evaluate the predictive capability of the GARS for drug therapeutic responses. The Wilcoxon rank test was then used to compare the difference in IC50 between the low and high GARS groups. Finally, we applied the “ggplot” R package to paint the result in the histogram.
