Hi,
I'm currently on 2 weekly Herceptin with continuous low-dose Xeloda. Have been on Herceptin/+or- chemo since 2001 for systemic disease in lymph system. Initial tumor marker analysis was with CEA, but levels were no longer elevated at third recurrence in Oct.2005. First HER-2/neu Serum test was performed (and Navelbine stopped) one month after starting Xeloda.
The most recent test in May showed normal levels, although my recent PET scan in July showed the affected nodes as stable with some shrinkage in the largest node, but several small areas of new activity. Apparently Xeloda/Herceptin is keeping the activity contained in my lymph system, as the Serum test is showing no circulating cells and PET and Brain MRI show no other activity.

Also, here's a link to the discussion that took place on the board earlier this year with Dr.Walt Carney of Oncogene Science:
