Hi,our story is similar,my dad dx 4-9-07 sclc mets to liver.He is very weak and frail,he is starting 3rd round of chemo.The onc.is much more upbeat than the radiologist was.My dad is very weak in his legs also.I am afraid to ask onc.about any kind of timeline,I fear the answer I may get.I will pray for you and your family,cancer is a terrible disease,what is so bad,my dad is sneaking a smoke,I can smell it.I try to to tell myself the harm is already done,goodluck to you.Take Care
