Predictive, Diagnostic evidence:
Predictive: The study discusses how multiple clinical-grade antiandrogens slowed the growth of and radiosensitized AR-positive GBM cell lines and patient-derived xenografts (PDXs), indicating a correlation between the androgen receptor (AR) expression and response to therapy. This suggests that AR expression may predict sensitivity to antiandrogen treatment in glioblastoma.
Diagnostic: The abstract mentions that nearly half of GBM cell lines, PDXs, and human tumors expressed AR, indicating that AR expression can be used to classify or define a subtype of glioblastoma, specifically AR-positive GBMs. This association with a specific characteristic of the tumors supports its use as a diagnostic marker.
