Thank you Tom ... Scott ( my husband) does have the ALK mutation , Adenocarcinoma . He is now in his 2nd week of taking Xalkori , after 1 initial round of IV chemo a month ago. As of this week his is no longer needing any pain meds , and feels pretty good. He is now eating and has gained 8 pds back of the intial 20 pd loss, due to not being able to swollow . His main tumor was making it difficult to even drink water. I pray he continues to feel good & it just keeps getting better .
