Treatment of multiple myeloma has substantially changed over the past decade with the introduction of several classes of new effective drugs that have greatly improved the rates and depth of response. Response criteria in multiple myeloma were developed to use serum and urine assessment of monoclonal proteins and bone marrow assessment (which is relatively insensitive) The Multiple Myeloma Response Criteria (IMWG) predicts disease response in multiple myeloma. This is an unprecedented time. It is the dedication of healthcare workers that will lead us through this crisis
The IMWG criteria should be used to diagnose plasma cell disorders (Grade C/IV; Table 1). The recommended investigations of a suspected myeloma should incorporate the tests in Table 2 (grade C/IV). Pretreatment Considerations: Definitions of Fit and Unfit Patients The operative cutoff age of 65 years is no longer sufficient t For all other patients, the IMWG had suggested criteria for the definition of renal response to therapy . 36 These criteria have been widely accepted and have been used worldwide for the evaluation of renal response in several studies. 37-41 Simplified criteria of renal response have also been proposed but must be tested in larger studies before their recommendation . 4 To ease diagnosis, several criteria based methods have been studied. Beside the one in the multiple myeloma diagnostic calculator above, there is the International Myeloma Working Group diagnostic criteria: Monoclonal plasma cells in marrow ≥ 10%

Results are based on a prespecified interim analysis with a median follow-up time of 20.7 months Following the International Myeloma Working Group (IMWG) criteria, it is essential to measure the measurable residual disease, but also the complete metabolic response (CMR), inside and outside the bone marrow (BM). 1 In the absence of standard imaging criteria for PET CMR, a combined analysis of two prospective imaging substudies from large phase III trials (IFM/DFCI 2009 2 and EMN02/HO95 3.

The new myeloma response criteria, on which the NCCN based its most recent revision, were developed and agreed upon by the more than 200 members of the IMWG. The new response criteria spell out. (IMWG) response criteria did not elicit such a separation between PR and very good PR. This trend was also seen in the validation cohort Response to treatment and duration of response vary widely in WM. Currently, there is no way to accurately predict how good or how long a response will be for an individual patient. One of the goals of WM researchers is to better determine how patients will respond to a particular treatment based on the variations in each person's disease biology and unique genetic makeup A post hoc analysis to evaluate the outcomes of patients with a response who had prolonged dose delays (in which ≥3 treatment cycles were missed) was performed. Of the patients who had a response according to IMWG criteria in the 2.5-mg/kg group, 16 of 31 patients (52%) had ≥1 prolonged dose delay

The diagnostic criteria of MM, ISS stage, and the international myeloma working group (IMWG) response were based on the precedent review . According to the serum PTH level at the time of MM diagnosis (cut-off; 68.3 pg/mL, reference range; 15-68.3 pg/mL), the study population was divided into non-high PTH group and high PTH group Thus, in 2016, the International Myeloma Working Group (IMWG) defined the presence of MRD in myeloma as having one tumor cell in at least 10 5 normal cells in BM (minimum sensitivity threshold of 10 −5), recognized its detection as an important endpoint, and updated the response criteria to include measurement of MRD as the deepest level of response that could be achieved Stringent complete response (sCR) criteria may not predict clinical outcomes for patients with multiple myeloma (MM) compared with complete response (CR) criteria, according to study findings.
