ALB and neoplasm: Figure 6C shows these results. The maximum tumor absorbed dose was estimated to be the lowest of the two values, obtained from the kidney maximum absorbed dose and the blood maximum absorbed dose. For all of the compounds, the dose-limiting organ was found to be the blood. 177Lu-Alb-L6, and to a lesser extent, 177Lu-Alb-L4, appear to be the more viable compounds with potential tumoricidal absorbed doses able to be delivered to the tumor.
