abstract = {Deletion 17p13, del(17p), is associated with poor outcome
in myeloma but some patients show long-term survival. With
the current study we intended to identify factors impacting
outcome of such high risk patients. We analyzed 110 newly
diagnosed, symptomatic patients with del(17p) detected by
fluorescence in situ hybridization (FISH) in CD138-purified
myeloma cells to identify prognostic factors for survival.
Age >65 years, ISS III, and elevated LDH negatively impacted
survival. Patients with subclonal $(10-60\%$ of plasma
cells) del(17p) had longer progression-free survival (PFS)
than patients with del(17p) in $>60\%$ of plasma cells (26
vs. 19 months, P = 0.03). Additional gain of 1q21 was
associated with shorter PFS (17 vs. 25 months,
P = 0.01). Hyperdiploidy did not ameliorate impact of
del(17p), but gain 19q13 predicted longer PFS (30 vs. 18
months, P = 0.01) and overall survival (50 vs. 29
months, P = 0.01). Multivariate analysis in transplant
eligible patients (≤65 years) revealed better survival for
patients treated with upfront autologous transplantation
(hazard ratio, $[95\%$ confidence interval]: 0.15 [0.04,
0.58], P = 0.006). Application of maintenance therapy
was associated with better survival in transplant-eligible
patients (0.30 [0.09, 0.99], P = 0.05). We demonstrate
heterogeneous outcome of patients with del(17p) according to
baseline characteristics and treatment. 19q13 should be
included in routine FISH panel, since gains were associated
with better survival. Am. J. Hematol. 91:E473-E477, 2016. ©
