What is resistance?

What is resistance?

Resistance is when the disease fails to respond or stops responding to a given therapy. Your doctor will schedule regular check-ups to measure your response to therapy. This will be done using blood and bone marrow tests. Resistance can occur at any time during treatment, even if you have been taking your medication successfully for several years. Because of this, resistance may be a possible cause for not meeting treatment goals.

There are 2 types of resistance:

  • Primary resistance is when you do not respond when first starting treatment
  • Secondary resistance is when you lose your response or stop responding later in treatment

Resistance is often, but not always, the result of mutations in the BCR-ABL gene that causes Philadelphia chromosome–positive chronic myeloid leukemia
(Ph+ CML).
