MGMT and glioma: The research focus has shifted from traditional topics such as the "MGMT gene" to emerging areas including the "tumor microenvironment," "immune infiltration," and "nanoparticles." The androgen receptor was identified as a promising but underexplored therapeutic target.<h4>Conclusions</h4>Research on glioma chemoradiotherapy resistance has seen substantial growth, with increasing emphasis on immune modulation, the tumor microenvironment, and novel therapeutic targets such as the androgen receptor.
