Background: Multiple myeloma (MM) is an incurable clonal neoplasm that usually requires long-term treatment, which may result in secondary cytopenia(s) and myeloid neoplasms. We investigated the landscape of mutations detected by NextGen sequencing (NGS) in myeloma patients with cytopenia.
Methods And Materials: MM patients (n = 196) with cytopenia(s) and NGS results were identified and divided into 4 groups: 1) patients with myeloma only and no myeloid neoplasms; 2) patients with myeloid neoplasms but no myeloma; 3) patients with concurrent myeloma and myeloid neoplasms; and 4) patients with no myeloma or myelodysplasia.
Results: The most frequently mutated genes were TP53, DNMT3A, TET2, ASXL1, and KRAS. TP53 mutations were predominantly found among patients with myeloid neoplasms with or without concomitant MM. SF3B1 and TET, the genes most commonly mutated in myelodysplastic syndromes, were less frequently identified among MM patients. ASXL1 mutations were more commonly associated with myeloid neoplasms, whereas KRAS and DNMT3A mutations were more closely associated with MM than myeloid neoplasms. RUNX1 mutations showed closer association with myeloid neoplasms. Fifty-eight patients harbored clonal myeloid gene mutations but no overt morphologic or cytogenetic abnormalities, of which 7 patients had myelodysplastic syndromes that was missed by the original pathologists. Thrombocytopenia appeared to be a more reliable marker than anemia or neutropenia to trigger work-up for myeloid neoplasms.
Conclusion: NGS could greatly help with diagnosing myeloid neoplasms in MM patients with cytopenia(s). The depicted gene landscape may facilitate our daily interpretation of NextGen sequencing (NGS).
