Chemotherapy drugs are designed to kill rapidly dividing cancer cells, but they can also affect other rapidly dividing cells in the body, including those in the gastrointestinal tract. When these drugs or their byproducts enter the bloodstream, they can stimulate the CTZ, triggering nausea and vomiting. Understanding the role of the CTZ can help in developing effective antiemetic therapies to improve the quality of life for cancer patients.
