If the disease has not gone into remission after Cycle 3, your next bone marrow aspirate will depend on your group. If you are in Group 1, you may have another aspirate about 3 weeks after you begin Cycle 4. After that, you may have an aspirate every 2 weeks (or more often if your doctor feels it is needed) until the response (or lack thereof) is confirmed. If you are in Group 2, you may not have another bone marrow aspirate until after the end of Cycle 6.
