Background Maintenance therapy following autologous stem cell transplantation can delay disease progression and prolong survival in multiple myeloma (MM). Ixazomib is ideally suited for maintenance therapy given its efficacy, convenient once-weekly oral dosing, and low toxicity profile. Methods The phase 3, double-blind, placebo-controlled, TOURMALINE-MM3 study randomised 656 patients with newly diagnosed MM from 227 clinical/hospital sites in 30 countries in Europe, the Middle East, Africa,
Gain of 12p material is invariably associated with testicular germ cell tumors (TGCTs) of adolescents and adults, most usually as an isochromosome 12p. We analyzed TGCTs with i(12p) using a global approach to expression profiling targeting chromosomes (comparative expressed sequence hybridization, CESH). This indicated overexpression of genes from 12p11.2-p12.1 relative to testis tissue and fibroblasts. The nonseminoma subtype showed higher levels of expression than seminomas. Notably, 12p11.2-p12.1 is amplified in about 10% of TGCTs and CESH analysis of such amplicon cases showed high levels of overexpression from this region. Microarray analysis, including cDNA clones representing most UniGene clusters from 12p11.2-p12.1, was applied to DNA and RNA from 5 TGCTs with amplification of 12p11.2-p12.1 and seven TGCTs with gain of the entire short arm of chromosome 12. Expression profiles were consistent with the CESH data and overexpression of EST595078, MRPS35 and LDHB at 12p11.2-p12.1 was detected in most TGCTs. High-level overexpression of BCAT1 was specific to nonseminomas and overexpression of genes such as CMAS, EKI1, KRAS2, SURB7 and various ESTs correlated with their amplification. Genes such as CCND2, GLU3, LRP6 and HPH1 at 12p13 were also overexpressed. The overexpressed sequences identified, particularly those in the region amplified, represent candidate genes for involvement in TGCT development.
The results of our prospective study have revealed great diversity in the treatment regimens used to manage MM in real-life practice. This diversity was linked to factors such as novel agent accessibility and evolving treatment recommendations. Our results provide insight into associated clinical benefits.
Background/aim: The disease caused by SARS-CoV-2 was named as COVID-19.There is as yet insufficient information about the effects of HSCT on the clinical course of COVID-19. In the present study, we aimed to investigate the clinical course of COVID-19 in patients who had undergone HSCT.
Materials and methods:We analyzed baseline characteristics, clinical course and findings of COVID-19, hospitalization and death rates, overall survival and case fatality rates of HSCT recipients diagnosed with COVID-19 retrospectively.Results: 57.6% of the patients underwent AHSCT, and 42.4% underwent allo-HSCT. 60.6%, 27.3%, and 12.1% of the patients had mild, moderate and severe COVID-19 or critical illness, respectively. 45.5% were hospitalized, and 12.1% required intensive care. 9.1% necessitated invasive mechanical ventilation. The total CFR was 9.1% in HSCT recipients, 22.2% in patients with active hematologic malignancy and 4.2% in patients without active hematologic malignancy.
Conclusion:It can be concluded that mortality of HSCT recipients is lower in patients whose primary disease is in remission compared to ones that are not in remission.Further studies with larger group patients are needed in order to delineate the effects of COVID-19 on HSCT patients.
Summary A series of adult testicular germ cell tumours consisting of eight seminomas, 14 non-seminomas (including two cell lines) and two combined tumours was analysed by comparative genomic hybridization and, in some cases, by interphase fluorescence in situ hybridization. The gain of 12p was identified in all cases and additional material from chromosomes 7 and 8 was found in over 70% of cases, in keeping with previous analyses. Other consistent regions of gain included 1 q24-q31 (50%), 2p16-pter (41%), 2q22-q32 (45%) and Xql 1-q21 (50%). The loss of 1p32-p36 (36%), 9q31-qter (36%), 1 1q14-qter (50%), 16p (36%) and 18p (45%) and the loss of material from chromosomes 4 and 5 (50% and 36% respectively) were also found in all histological subtypes. The loss of 1 p material was confirmed in four cases by interphase FISH analysis and shown, with one exception, not to involve the loss of the D1Z2 locus at 1 p36.3, which is commonly deleted in paediatric germ cell tumours. An association between gain of 6q21-q24 with cases resistant to chemotherapy (P < 0.01) was observed. In addition, loss of chromosome 19 and 22 material and gain of 5q14-q23, 6q21-q24 and 13q were found at a significantly lower frequency in seminoma than non-seminoma. These regions may contain genes involved in the divergent development of seminoma and non-seminoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
