case_images: Partial response was achieved on the first re-staging scan (Figure 2).
case_images: Levels of alkaline phosphatase (IU/L) at baseline and during the course of therapy. Levels corresponded to her radiological response, with initial partial response followed by stable disease

case_images: The patient's alkaline phosphatase levels corresponded to the disease response, leading us to believe it was most likely produced by the cancer cells, as there was no evidence of bone invasion (Figure 3).
