VEGFA and oropharynx cancer: In conclusion, the early intra-treatment DCE-MRI parameter ktrans and plasma VEGF levels emerged as the two most robust predictors for treatment response to cCRT in HPV-negative oropharyngeal cancer, yielding effective predictive models with cut-off values of 0.259 min−1 for ktrans and 62.5 pg/mL for plasma VEGF.
