Abstract

To evaluate the specific prognostic value of CAs, we conducted an analysis of 923 symptomatic multiple myeloma patients. Among this cohort, 480 patients had complete data set of high-risk CAs by interphase fluorescent in situ hybridization at diagnosis. In the high-risk group analysis, the median OS of patients without CAs (n = 338, 72 %) was 6.5 years, patients with del(17p) (n = 42, 9 %) was 4.4 years, patients with t(4;14) or t(14;16) (n = 72, 15 %) was 4.4 years, and patients with double-positive CAs(del(17p) and t(4;14) or t(14;16)) (n = 18, 4 %) was 2.1 years (p = 0.032). Patients with double-positive CAs had a significantly worse prognosis.
