- Description
- A 51-year old female never smoker with stage IV lung adenocarcinoma carrying a HER2 insertion in exon 20 (p.A775_G776insYVMA) by sequencing archived material, HER2 overexpression by IHC (2+) and HER2 amplification by in situ hybridization was treated with T-DM1 (trastuzumab emtansine). Patient received two cycles off-label at 3.6mg/kg and was found to have morphologic response of lung and bone lesions by PET and CT. TDM-1 therapy was ongoing as of publication April 2015.
