Key Points• MRD assessment by sequencing is prognostic of TTP and OS in multiple myeloma patients.• Among patients in complete response, MRD assessment by sequencing enables identification of 2 distinct subgroups with different TTP.We assessed the prognostic value of minimal residual disease (MRD) detection in multiple myeloma (MM) patients using a sequencing-based platform in bone marrow samples from 133 MM patients in at least very good partial response (VGPR) after front-line therapy.Deep sequencing was carried out in patients in whom a high-frequency myeloma clone was identified and MRD was assessed using the IGH-VDJ H , IGH-DJ H , and IGK assays. The results were contrasted with those of multiparametric flow cytometry (MFC) and allelespecific oligonucleotide polymerase chain reaction (ASO-PCR).

Structural haemoglobinopathy should be investigated in subjects belonging to ethnic groups with high prevalence of variant Hb and with a score of 3 or 4. Erythrocytes of HbAC subjects are smaller and denser than those of HbAS subjects.

The therapeutic effects of bortezomib in untreated and refractory/relapsed multiple myeloma have been demonstrated in several clinical trials, displaying superiority to the conventional treatments. However, many treatment-related toxicities, such as bone marrow suppression, infections and peripheral neuropathy, are well known and lead to treatment discontinuation and dose modification, especially in elderly patients. The purpose of this review is to summarize the published literature concerning the efficacy and safety of reduced-intensity induction therapy with bortezomib-based regimens in elderly patients with multiple myeloma. We used the VISTA trial as a reference and compared it with the seven trials identified in a systematic search. The data suggest that low-dose bortezomib significantly reduces therapy-related toxicities, especially neuropathy, and decreases the rate of discontinuation compared with the twice-weekly regimen, without losing efficacy. In light of this review, we suggest that once-weekly infusion of bortezomib in addition to melphalan–prednisone may be considered as a new standard of care in frontline treatment of elderly patients with symptomatic multiple myeloma.

Previously described differences between δβ-TT, β-TT and IDA in the corpuscular indices of mature red blood cell can also be observed in reticulocytes. The degree of anisocytosis in reticulocytes from patients with thalassaemia is correlated with HbF.
