...we divided the patients into MHC-H and MHC-L groups according to the median level of the MHC-II signature score of all samples....The IC50 values of Cisplatin, Docetaxel, Sunitinib, and NU.7441 in the MHC-H group were significantly lower than those of the MHC-L group, and all of these values were significantly correlated with the MHC-II signature score all P < 0.001...Finally, we identified a significant increase in drug sensitivity to cisplatin, docetaxel, sunitinib and NU.7441 in the MHC-H group.
