(Rohit asks Levy) How do you interpret HER2 IHC scores when determining treatment for patients with NSCLC? How does this influence your therapeutic decisions?
When applying HER2 scoring and considering ASCO/CAP guidelines in NSCLC, do you follow breast cancer scoring guidelines, or have you considered using gastric cancer scoring?
How do you interpret equivocal or borderline results? Are there any specific considerations or additional testing you recommend for this group?
