Medicare and patient spending among beneficiaries diagnosed with chronic myelogenous leukemia.

Older patients with CML with adequate time receiving TKI therapy have 5-year survival rates that are comparable to those of their counterparts without cancer. However, TKI use is accompanied with significant Medicare and patient spending; patients receiving multiple TKIs (ie, dasatinib or nilotinib along with imatinib) constitute the group with the highest spending.
