4.3 Treatment after progression

Some GISTs grow while taking drug treatment.

Doctors call this cancer progression. Treatment

options after progression are presented next.

Chart 4.3.1

lists treatment options based on

whether there is limited or widespread growth.

If limited growth, you may keep taking imatinib

and consider local treatments. Otherwise, you may

increase the dose of imatinib or start taking sunitinib.
