ABSTRACT
BACKGROUND:
Vascular endothelial growth factor (VEGF) has been shown to induce neurogenesis in the brain and yield neuroprotective effects. It is hypothesized that chemotherapy reduces circulating VEGF levels and leads to cognitive decline among patients. This multicenter longitudinal study aimed to evaluate the impact of chemotherapy on VEGF levels and the association between VEGF levels and cognitive function. PATIENTS ANDMETHODS:
A total of 145 early-stage breast cancer patients were recruited and assessed before chemotherapy (T1), during chemotherapy (T2), and at the end of chemotherapy (T3). At each time point, plasma VEGF levels were assessed using a multiplex immunoassay. Cognitive function was assessed using both Functional Assessment of Cancer Therapy-Cognitive Function, Version 3 (FACT-Cog), and Headminder (a computerized, web-based neuropsychologic battery).RESULTS:
Generally, we observed higher-than-baseline plasma VEGF levels after the start of chemotherapy (P < .001). Among patients receiving anthracycline-based chemotherapy, the median plasma VEGF levels were significantly higher at T2 (T2 37.3 pg/mL vs. T1 21.3 pg/mL; P < .001) and T3 (T3 35.5 pg/mL vs. T1 21.3 pg/mL; P < .001) than at baseline. Plasma VEGF levels were not associated with chemotherapy-associated cognitive impairment.CONCLUSION:
Breast cancer patients experience an increasing trend in plasma VEGF levels during chemotherapy, and the regimen types may have a differential effect on circulating VEGF levels. Furthermore, changes in plasma VEGF levels during chemotherapy were not associated with cognitive impairment. VEGF may play a minor role in mediating the occurrence of chemotherapy-associated cognitive impairment.Palabras clave
