abstract = {[18F]FDG PET/CT is the elective imaging modality for
treatment monitoring in multiple myeloma (MM). However, MM
is a heterogeneous disease from an imaging point of view,
raising challenges in interpretation of PET/CT. We herein
investigated the prognostic role of the novel Italian
Myeloma criteria for PET Use (IMPeTUs) in MM patients
undergoing high-dose chemotherapy (HDT) followed by
autologous stem cell transplantation (ASCT).Forty-seven
patients with newly diagnosed MM underwent [18F]FDG PET/CT
before commencement of treatment (baseline PET/CT).
Thirty-four of them $(72.3\%)$ were also examined after
completion of ASCT (follow-up PET/CT). PET/CT analysis was
based on the IMPeTUs criteria, which take into
consideration-among others-the metabolic state of the bone
marrow based on the 5-point Deauville score (DS), the number
and metabolic state of focal [18F]FDG-avid lesions, as well
as the presence of paramedullary disease (PMD) and
extramedullary disease (EMD). We analyzed whether parameters
from IMPeTUs correlate with clinically relevant parameters
and patients' outcome, as assessed by progression-free
survival (PFS).Median follow-up from baseline and follow-up
PET/CT were 85.1 months and 76.7 months, respectively. The
number of focal, [18F]FDG-avid lesions significantly
correlated with the bone marrow infiltration rate and the
R-ISS stage, while the presence of PMD was associated with
LDH. After univariate survival analysis, the number of
focal, [18F]FDG-avid lesions both before and after therapy
as well as the presence of PMD and EMD before therapy
adversely affected PFS. Multivariate survival analysis for
baseline parameters confirmed that the number of focal,
[18F]FDG-avid lesions and the presence of EMD are associated
with adverse prognosis, irrespective of the ISS stage and/or
the presence of high-risk cytogenetic abnormalities. The
5-point DS of [18F]FDG uptake in reference bone marrow and
focal lesions showed a significant decrease as response to
treatment, but it did not affect PFS.Several parameters
utilized in IMPeTUs predict PFS in MM patients, suggesting
the potentially significant role of the new criteria in
patient stratification and response assessment. Additional
studies are warranted for the further evaluation of IMPeTUs
in the direction of establishment of robust cut-off values
with a prognostic significance in the disease.},
