Is it feasible to treat central liver tumors +/- portal vein thrombus with SBRT while minding central hepatobiliary tract constraints?

Remember that biliary strictures frequently cause death in these patients because stents don't always drain after these high doses of radiation. I have personally never caused a biliary stricture. The regimens that I am using with an SBRT technique are below the threshold for biliary stricture and r...

The Stanford group has done some very nice work investigating the tolerance of central liver. Given the bile duct is not often easily seen on cross sectional imaging, these authors suggest using a fixed margin (1.5 -2 cm) around the PV (from the spleno-portal confluence to the PV bifurcation) analog...
