Thank you all so much for the information. I still feel lost though. I'll try to answer some of the questions that were asked. I live in Franklin Co. Virginia and my mom is receiving treatment from Lewis-Gale Clinic in Salem, VA. I know we should have received a second opinion but we were all scared and thought she needed treatment immediately. She has had symptoms since January and went to doctor after doctor. They would tell her she had acid reflux, then maybe a hernia, her gallbladder was checked. Finally after four months they found out she had pneumonia and then everything started to unravel. The pulmonary specialist who did the biospy said we could obtain a second opinion but he was positive of the diagnosis. We felt confident in the doctors and wanted to trust their judgement. When she was diagnosed with LC they had done a biopsy of her lung tissue and a PET scan. The oncologist said because she had the brain lesions and needed radiation, he didn't want to start chemo yet. So instead he wrote her a prescription for Tarceva. This was on a Friday, and none of the pharmacies around had it. So we had to wait until Monday for it to be ordered. The Dr. had a few Iressa pills and told her to take them until the Tarceva came in. She took 4 days of Iressa and then started the Tarceva. The next month when her CEA had dropped to 900 (originally 11,400)he said the Tarceva was working and she would just stay on that and evaluate each month with bloodwork and a chest xray. The second month the count had only dropped to 811 so he started giving her Gemzar treatments. She was taking chemo, once a week for two weeks, and then off a week. She had four treatments total. (She also had to skip a treatment because of an infected toenail)After the first set of treatments her count dropped to 400. Then three weeks later it went back up to 850 and he said the chest xray showed growth. The Dr. said he wanted to try the Iressa for two weeks. So we go back Thursday. I hope maybe this is a little clearer than my first post. Anyone please feel free to send me any comments. Thanks for everyone who responded-God bless you all!!
