Redefining attrition in multiple myeloma (MM): a Canadian Myeloma Research Group (CMRG) analysis.

ABSTRACT: While most patients diagnosed with multiple myeloma (MM) receive initial therapy, reported attrition rates are high. Understanding attrition rates and characteristics of patients not receiving subsequent therapy is useful for MM stakeholders.

A total of 5548 patients were identified, 3111 autologous stem cell transplant (ASCT) patients and 2437 non-ASCT.
