Which statement about intraarterial chemotherapy administration is correct?

• A. A catheter is inserted into an artery and connected to a pump that infuses chemotherapy
• B. Medication is taken orally as a pill
• C. The chemotherapy is delivered via a topical cream
• D. No vascular access device is used

Answer: (A)

Intraarterial chemotherapy is delivered by placing a catheter into the artery that feeds a tumor and connecting it to a pump that continuously infuses the drug. This regional approach concentrates the chemotherapy at the tumor site, allowing a high local drug dose with potentially less systemic exposure, and it typically requires interventional radiology to thread the catheter precisely into the relevant artery. The other statements don’t fit because oral pills deliver systemic chemotherapy through the entire body, topical creams are used for surface skin treatments and don’t access the arterial supply, and no vascular access device would prevent delivering the drug directly into an artery.
