So..sounds like Lapatinib isn't more effective in tumors with or w/o p95, but that Herceptin is less effective in those tumors with p95. Maybe that's another reason some patients benefit from getting both. Without knowing whether the tumor has this quality, using both might cover the bases.
Any available test for p95 her2?
