result update

Recd my dad 2nd CT scan for his 4th round of Chemo, quite a good result, the cell continue to shrink, Doc wants him to carry on with 2 more cycle before letting him on mantainance which he say that its will be in oral pill form.. i din get a chance to talk to the Head of dept as he quite busy... but i can confirm that its is not Tracva.. anyone had this? and will the side effect be even worst then chemo.. one thing i am happy is that my dad is gaining weight....
