after a first line therapy that has such associated toxicity

All the first line traditional chemo therapies have substantial toxicity of one form or another. None work that well in advanced disease - hence the excitement about Erbitux and Avastin.

Juggling combinations of chemo drugs is always a learning experience. Sometimes getting just the right combination and dosing makes a dramatic difference - testicular cancer is a good example, where long term responses went from close to zero to something like 90% with essentially no new drugs, just different doses and combinations of existing ones.
