BACKGROUND & OBJECTIVES: Multiple myeloma (MM) is a plasma cell malignancy characterized by cytogenetic heterogeneity. In comparison with conventional karyotyping, fluorescence in situ hybridization (FISH) can efficiently detect various genetic changes in non-cycling plasma cells in 50-90 per cent of MM cases. The present study was undertaken in MM patients to evaluate the frequency and clinico-pathological significance of various cytogenetic abnormalities in the Indian population. METHODS: Interphase FISH was applied on purified plasma cells of 475 patients with MM using specific probes...

OBJECTIVE: To explore the influence of chromosome abnormality on therapeutic efficacy and prognosis of patients with newly diagnosed multiple myeloma(MM) treated with bortezomib. METHODS: The clinical data of 152 patients with newly diagnosed MM were collected from January 2008 to December 2011. All patients received bortezo-mib-based chemotherapy and the therapeutic efficacy were investigated for 4 cycles later. The R banding and DNA probe were used to analyze the chromosome and gene (RB1 deletion, D13S319 deletion, P53 deletion, IgH rearrangement and 1q21 amplification) of chromosome specimens...

The study aimed to assess prognostic significance of del(13q14), del(17p13), t(4;14)(p16;q32), and amp(1q21) in newly diagnosed myeloma patients treated mostly with thalidomide-based therapies. All genetic abnormalities except del(13q14) were independent prognostic factors associated with shortened progression-free survival (PFS) and overall survival (OS). Patients with no abnormalities, one abnormality, and ≥2 abnormalities had a median PFS of 41.8, 17.0, and 10.0 months, respectively; a median OS was not reached, 48...

Hyperhaploid clones (24-34 chromosomes) were identified in 33 patients with multiple myeloma (MM), demonstrating a novel numerical cytogenetic subgroup. Strikingly, all hyperhaploid karyotypes were found to harbor monosomy 17p, the single most important risk stratification lesion in MM. A catastrophic loss of nearly a haploid set of chromosomes results in disomies of chromosomes 3, 5, 7, 9, 11, 15, 18, 19 and 21, the same basic set of odd-numbered chromosomes found in trisomy in hyperdiploid myeloma. All other autosomes are found in monosomy, resulting in additional clinically relevant monosomies of 1p, 6q, 13q and 16q...

Autologous transplantation is controversial for older patients with multiple myeloma. The role of age-adjusted high-dose melphalan and the impact of induction chemotherapy cycles is still unclear. A total of 434 patients aged 60-70 years were randomly assigned to 4 cycles of standard anthracycline-based induction chemotherapy or no induction. For all patients, double autologous transplantation after melphalan 140 mg/m(2) (MEL140) was planned. The primary end point was progression-free survival. Of 420 eligible patients, 85% received a first transplant and 69% completed double transplantation...

The gain/amplification of the CKS1B gene on chromosome 1q21 region is associated with a poor outcome in patients with multiple myeloma (MM). However, there are limited data on the outcome of patients with CKS1B amplification after a single high-dose chemotherapy and autologous hematopoietic stem cell transplantation (auto-HCT). We retrospectively evaluated the outcome of patients with CKS1B amplification who received an auto-HCT between June 2012 and July 2014 at our institution. We identified 58 patients with MM and CKS1B gene amplification detected by fluorescent in situ hybridization (FISH)...

Although generally not applied as first-line treatment of multiple myeloma, allogeneic hematopoietic cell transplantation (allo-SCT) can still be chosen as ultimate escalation approach in high-risk patients, preferentially within the framework of clinical trials. In this study, we investigated whether decreasing donor chimerism (DC) is predictive for relapse. In addition, we comprehensively determined the impact of several other disease- and treatment-related factors on outcome. One hundred fifty-five multiple myeloma patients whose DC status was followed serially by the short tandem repeat-based techniques at a single lab were included in this retrospective study...

Cytogenetic aberrations detected by interphase fluorescence in situ hybridization (iFISH) of plasma cells are routinely evaluated as prognostic markers in multiple myeloma. This long-term follow-up study aimed to assess the prognosis of systemic light chain amyloidosis (AL) patients treated with high-dose melphalan (HDM) chemotherapy and autologous stem cell transplantation, depending on iFISH results. Therefore, we analyzed a consecutive cohort of 123 AL patients recruited from 2003 to 2014. HDM was safe, with only 1 of 123 patients dying as a result of treatment-related mortality, and effective, with a complete remission (CR) rate of 34%...

Multiple myeloma (MM) is the second most common hematologic neoplasms and an appropriate in vivo environment for myeloma cells has potential implications for initiation, progression, and metastasis of MM. Exosomes, entities carrying microRNAs (miRNAs) to target locations, participate in the cross-talk between myeloma cells and nonmalignant components of the in vivo environment. This study disclosed the emerging roles of circulating exosome-associated miRNAs in drug resistance (DR) of MM. To this end, the medical records of consecutively hospitalized MM patients, who received novel agents-based therapies, were analyzed...

The prognostic heterogeneity of multiple myeloma (MM) is largely due to different genetic abnormalities. Cytogenetic analysis has revealed that most of MM harbor chromosome aberrations. Amplification of 1q21 is one of the most common chromosomal aberrations. Interphase fluorescence in situ hybridization was applied to detect the 1q21 amplification in 86 Chinese patients with newly diagnosed MM. Amp(1q21) was found in totally 40 of 86 (46.5%) cases, among which 29 with three copies of 1q21 and eleven with at least four copies of 1q21...

Many hematological malignances involve recurrent chromosomal abnormalities, and the reciprocal translocation is one of them. However, there are a lot of chromosomal abnormalities with lower incidence and unclear clinical significance. Among them, the one abnormal karyotype translocation, t (1;12) (q21; p13) is a rare karyotype change. Only 6 patients had been reported to have this karyotype and all of them suffered from hematologic diseases, including one case of acute myeloid leukemia, one case of high-risk myelodysplastic syndrome, two children with acute lymphoblastic leukemia, one case of chronic myeloid leukemia at accelerated phase and one case of multiple myeloma...
