Fig. 2From: The effect of an adenosine A2A agonist on intra-tumoral concentrations of temozolomide in patients with recurrent glioblastomaMean temozolomide concentrations. Plasma temozolomide systemic concentrations unchanged with regadenoson treatment (a). Non-contrast enhancing brain interstitium (BI) temozolomide concentration over time failed to increase with regadenoson (b). Contrast enhancing BI temozolomide concentration demonstrated a slight increase in temozolomide concentration over time (c). Error bars represent standard error of mean valuesBack to article page
