Diagnostic and molecular testing patterns in patients with newly diagnosed acute myeloid leukemia in the Connect® MDS/AML Disease Registry

Daniel A Pollyea et al. EJHaem. .

Abstract

Diagnostic and molecular genetic testing are key in advancing the treatment of acute myeloid leukemia (AML), yet little is known about testing patterns outside of clinical trials, especially in older patients. We analyzed diagnostic and molecular testing patterns over time in 565 patients aged ≥ 55 years with newly diagnosed AML enrolled in the Connect® MDS/AML Disease Registry (NCT01688011) in the United States. Diagnostic data were recorded at enrolment and compared with published guidelines. The percentage of bone marrow blasts was reported for 82.1% of patients, and cellularity was the most commonly reported bone marrow morphological feature. Flow cytometry, karyotyping, molecular testing, and fluorescence in situ hybridization were performed in 98.8%, 95.4%, 75.9%, and 75.7% of patients, respectively. Molecular testing was done more frequently at academic than community/government sites (84.3% vs 70.2%; P < .001). Enrolment to the Registry after 2016 was significantly associated with molecular testing at academic sites (odds ratio [OR] 2.59; P = .023) and at community/government sites (OR 4.85; P < .001) in logistic regression analyses. Better understanding of practice patterns may identify unmet needs and inform institutional protocols regarding the diagnosis of patients with AML.

Frequency of ASH/CAP guideline‐recommended tests among patients who received any molecular genetic testing (n = 429). Recommendation #16 of the ASH/CAP guidelines recommends that all patients with AML should be tested for FLT3. As per recommendation #17, those with CBF‐AML should also be assessed for KIT mutations. Recommendation #19 notes that patients who do not have CBF‐AML, APL, or AML associated with MDCA should undergo mutational analysis for NPM1, CEBPA, and RUNX1. Text listed in red refers to the proportion of patients who received testing that is strongly recommended in the ASH/CAP guidelines, while white text refers to the proportion of patients who received testing that is recommended.
