Peg,
I'm so sorry for what you and your husband are going through. My 48 year old sister has Stage 4 NSCLC (dx 07-02). As you can imagine, she also has been through alot... and also has a teenage son (and a husband!). The best analogy she can describe is sometimes an oncologist visit feels like a bat was swung at the back of her knees and she is painfully laid out on the floor. After the "beating", she will cry awhile, then get up and face the news.
She has been through brain surgery, whole brain radiation, four months of chemotherapy, and is currently taking a chemo "break". She is, at this moment, doing a few alternative treatments, and will probably return to a different chemo "cocktail". Her cancer is growing too. One thing that has been helpful to her, and I know it may sound "farout", is acupuncture. Now, if you knew my sister, you'd know what a "conservative" person she is, but she has benefitted from acupuncture. NOT to treat the cancer, but to help ease the side effects of chemo and other medications.....
I urge you both not to give up hope. Prolonged hopelessness guarantees defeat. I am an LPC (counselor), and I firmly believe that the mind and body are closely intertwined. (Not that we aren't allowed to greive and to feel sorry for ourselves at times). Lung cancer is the scariest and fiercest disease to hit my family in my lifetime..... and I'll bet in yours too. Your husband is a lucky man to have you. I'll be praying for you both.
Oh, and I say "go for" a clinical trial if it sounds reasonable. Or Iressa. IF that is what your husband wants. That is what I will encourage my sister to do if and when those options are discussed with her, if and when she asks my opinion -- which she usually does. (We, her family, have learned to respect and support her decisions, because ultimately, the decisions belong to her). Stay strong, Peg.
