A new study found that injections of the neurotransmitter dopamine can improve blood flow to tumors and delivery of an anticancer drug, doubling the amount of drug reaching tumors and increasing its effectiveness. Dopamine also raised tumor oxygen levels, which typically improves the effectiveness of both chemotherapy and radiation therapy. The study suggests a use for dopamine in treating cancer and perhaps other disorders in which normalizing abnormal blood vessels might improve therapeutic responses.
