NSCLC HER2 Mutation Treatment - 1270461

First, I want to say “thank you” for creating this forum where patients and their families have a chance to ask questions and get feedback from experts that they may not have access to otherwise. It is so appreciated at a time like this. My mom was diagnosed with Stage I lung cancer in 2007 in her right upper lobe. This lobe was removed using the VATS procedure and no further treatment was deemed necessary. She diagnosed again in 2011 with Stage I adenocarcinoma lung cancer and since it was confirmed to one spot, it was treated with Stereotactic Radiosurgery and no further treatment was deemed necessary. She has now been diagnosed again this month with Stage II B adenocarcinoma lung cancer with the HER2 mutation. This time there are multiple spots in her middle right lobe as noted on the PET scan. She is a very healthy, active 79 year old that is currently not on any other medications. She was told surgery to remove the middle lobe was too much for her. She is looking at treatments with oral drugs specifically afatinib although combination treatments sound more promising after reading through your site. Are there any clinical trials that she would be eligible for given her history and tumor type?
