ABSTRACT
Conventional cytogenetic analyses and fluorescent in situ hybridization (FISH) are helpful for stratifying patients with multiple myeloma (MM) into high-risk [t(4;14), t(14;16), and/or del 17p] and standard-risk [t(11;14)] categories. However, the prognosis of patients with MM treated with autologous stem cell transplantation (ASCT) stratified according to these categories remains unclear. This retrospective observational study analyzed 97 patients with MM who received a single, planned ASCT after treatment with 200 mg/m2 melphalan between 2001 and 2011. The patients were grouped according to chromosomal abnormality, including t(11;14) (nâ¯=â¯45), t(4;14) (nâ¯=â¯31), del 17p (nâ¯=â¯10), t(11;14) with del 17p (nâ¯=â¯7), and t(4;14) with del 17p (nâ¯=â¯4). Median overall survival (OS) of the t(11;14) group (64.1 months) was not significantly different from that of the t(4;14) group (not reached), but it was significantly longer than that of the del 17p group (23.0 months; Pâ¯=â¯.002). G-banding revealed that the median OS of the t(11;14) group with additional chromosomal abnormalities (ACAs) (46.2 months) was significantly shorter than that of the t(11;14) group without ACAs (not reached; Pâ¯=â¯.005) and the t(4;14) group (not reached; Pâ¯=â¯.010). These findings highlight the importance of G-banding in patients with t(11;14) MM.
