Hi Lyn, Not being a doctor, I don't know much about how this combo works for lymph nodes. This is a phase 1 clinical trail so I believe they are establishing safety and dosage. I'm in the high dose group. I heard some of the patients are getting good results, but not all. Avastin has only been approved for colorectal cancer. They are testing it alone and with various other drugs to see what works for metastatic breast cancer. The results of my trail are not in yet as it just started in December. I believe they publish results when the trails are finished. There are other Avastin trails listed on-
http://clinicaltrials.gov/. I've basically become a guinea pig in order to get this cutting edge treatment. Hope this helps and all the best, Carol
