'It’s traveling through the entire blood stream of the liver or pancreas not just the tumor.

With all due respect, you should consider some detailed research prior to making statements like this.

'Healthy liver tissue derives up to 90% of its blood supply from the portal vein with only a small amount of the blood supply being derived from the hepatic artery. In contrast, liver tumours derive up to 90% of their blood supply from the hepatic artery since they need a profuse supply of highly oxygenated blood. The hepatic artery therefore provides an ideal channel to deliver targeted treatment to the tumour.'
