Prognostic Value and Efficacy Evaluation of Novel Drugs for Multiple Myeloma Patients with 1q21 Amplification (Amp1q21) Only: A Systematic Review of Randomized Controlled Trials.

ABSTRACT: Background: Multiple myeloma (MM) is a heterogeneous disease characterized by chromosomal translocation, deletion, and amplification in plasma cells, resulting in a huge heterogeneity in its outcomes. Of all these cytogenetic abnormalities, Amp1q21 is most commonly detected, which is always associated with significantly shorter progression-free survival (PFS) and overall survival (OS) than normal 1q copy number status. In the era of novel agents such as bortezomib, ixazomib, lenalidomide, a head-to-head comparison of all these agents is still absent, especially in the patients with Amp1q21 alone. So, aiming to explore the optimum therapy to the patients with Amp1q21 only, we conduct this study. Patients and Methods: We searched the PubMed, the Cochrane Library, PMC and the Embase databases, and we selected all the randomized controlled trials (RCTs) in English about MM with Amp1q21 up to April, 2019. A total of 72 papers were full screened and finally 2 literatures can be included in our study. Results: Of the two studies, the one is about IRd (ixazomib, lenalidomide, dexamethasone) vs. placebo-Rd (HR, 0.781; 95% CI, 0.492-1.240), another is about VAD (vincristine, adriamycin, dexamethasone) vs. PAD (bortezomib, adriamycin, dexamethasone) (3-year survival rate: 59% vs. 83%, p=0.016). Conclusion: From this review, MM patients with Amp1q21 may somewhat benefit from ixazomib but the evidence is still stuffless. What's more, a head-to-head comparison between ixazomib and other agents among MM patients with Amp1q21 is also absent. So, we sincerely expect this review can attract some attention for the therapy of this special part of patients. This study was registered in https://www.crd.york.ac.uk/prospero/#recordDetails.

Project description:Background: Arrhythmias are common cardiovascular complications in multiple myeloma (MM) patients and are related to a poor prognosis. Objective: This study aimed to assess the burden of arrhythmias and their prognostic value in patients with MM. Methods: This was a retrospective study of patients with MM between January 2015 and April 2020 at the First Affiliated Hospital of Xi'an Jiaotong University. The incidence of arrhythmia and associated risk factors were evaluated. The relationship between the type of arrhythmia and survival was analyzed. Results: A total of 319 patients with MM were identified, and 48.0% (153/319) had arrhythmias. The most common type of arrhythmia was sinus tachycardia (ST) (15.0%, 48/319), followed by sinus bradycardia (SB) (14.4%, 46/319), premature atrial contractions (PACs) (6.3%, 20/319), conduction disorders (CDs) (6.0%, 19/319), atrial fibrillation (AF) (6.0%, 19/319), premature ventricular contractions (PVCs) (4.4%, 14/319) and paroxysmal supraventricular tachycardia (PSVT) (0.6%, 2/319). The patients with arrhythmias had higher levels of log NT-proBNP and creatinine, greater bortezomib use, and a higher incidence of diabetes than those without arrhythmias (P < 0.05). The all-cause mortality rates of patients without arrhythmias and those with AF, ST, PACs, CDs, SB, and PVCs were 50.6% (84/166), 73.7% (14/19), 60.4% (29/48), 60.0% (12/20), 52.6% (10/19), 34.8% (16/46), and 28.6% (4/14), respectively. In a subgroup analysis of patients experiencing different types of arrhythmias, patients with SB had lower all-cause mortality than patients with AF (P < 0.01). Univariate and multivariate Cox analyses showed that there was a positive statistically significant association between SB and survival (HR: 0.592 [0.352-0.998], P = 0.049) in a subgroup analysis of different arrhythmias. Conclusions: Patients with MM had a heavy arrhythmia burden, and in this study, approximately half of MM patients had arrhythmias. MM patients with SB were associated with lower all-cause mortality than those with AF. SB might be an independent positive factor for prognosis.
