...later treated w/ CABO. Activity noted. Interesting, no? My conjecture is that either the AE was too stressful...or the vandetanib less than effective... Is it a sound inference to suggest that-for some patients-CABO may prove to be a best,if only more effective choice. Conversely, I have been looking for a former CABO recipient...currently treated w/ vandetanib. I can find no evidence of this... Anyone...?
