Introduction
The updated criteria for multiple myeloma (MM) diagnosis
requires evidence of either 10% or more clonal plasma cells in
bone marrow examination or a biopsy-proven plasmacytoma in
addition to the presence of one or more myeloma defining events
(MDE). MDE consists of established CRAB features (hypercalcemia,
renal failure, anemia, or lytic bone lesions) as well as 3 specific
biomarkers: clonal bone marrow plasma cells ≥60%, serum free
light chain (FLC) ratio ≥100 (provided involved FLC level is ≥100
mg/L), and more than one focal lesion on MRI [1].
Important considerations in myeloma diagnosis
i. The levels of monoclonal (M) proteins and FLC in blood
are assessed routinely to confirm active disease [2]. The M
protein is considered measurable if it is ≥1 g/dL in the serum.
The serum FLC assay is particularly useful in patients who
lack a measurable M protein, provided that the FLC ratio is
abnormal and the involved FLC level is ≥100 mg/L [1].
ii. The evaluation of M-protein in urine is less widespread across
clinical practice [2]. The M protein is considered measurable
if it is ≥200 mg/day in the urine [1].
iii. Routine bone marrow assessment (aspirate or biopsy)
remains key in the establishment of MM diagnosis in clinical
practice, as reflected in the updated International Myeloma
Working Group (IMWG) diagnostic criteria [2].
iv. The creatinine clearance test or estimated glomerular
filtration rate (calculated using either the Modification
of Diet in Renal Disease [MDRD] study or Chronic Kidney
Disease Epidemiology Collaboration [CKD-EPI] equations)
are also performed at diagnosis to assess renal function [2].
v. Skeletal surveys using X ray do not reveal lytic bone disease
until 70% of the bone has decalcified [3]. Whole body low
dose computed tomography (CT) or magnetic resonance
imaging (MRI) is now recommended by the European
Myeloma Network (EMN) and the IMWG as standard for the
detection of lytic or focal lesions. Both are more sensitive
than conventional skeletal survey using X ray for detecting
bone disease [2]. MRI of the spine and pelvis are particularly
valuable for detection of focal lesions and may be used if
whole body imaging is not available [3].
Abstract
This article tries to answer the following questions
i. Is it necessary to incorporate cytogenetic risk categorization in induction decision making?
ii. What are the criteria used to assess eligibility for autologous stem-cell transplant (ASCT)?
iii. The role of tandem transplantation
iv. The role of consolidation and maintenance therapy today
v. Is the use of MRD assessment have any role after transplant?
