Cytokines as mediators of chemotherapy-associated cognitive changes: current evidence, limitations and directions for future research.
<h4>Objectives</h4>While various clinical and pharmacological determinants for chemotherapy-associated cognitive impairment have been identified, conflicting evidence suggests that cytokines might play an intermediary role. The objective of this systematic review was to evaluate the curr...
