Impact of Regional Income and Insurance Status on Survival of Multiple Myeloma Patients: Autologous Stem Cell Transplant as an Equalizer

Patients with Multiple Myeloma (MM) are enjoying significant improvement in overall survival as the result of advent of novel anti-myeloma agent that replace traditional chemotherapy, in addition to the increased use of transplant. The prices of novel agents, especially oral ones, have been rapidly escalating and there are well-described issues with affordability (Shih et al. JCO 2017). We therefore hypothesized that insurance status influences MM patients (pts) survival. National Cancer Database (NCDB), covering 70% of MM patient nationwide was utilized.

CONCLUSIONS: Although our meta-analysis showed statistically significant increased risks of either cancer incidence or mortality of certain cancers in association with firefighting, a number of important limitations of the underlying studies exist, which, precluded our ability to arrive at definitive conclusions regarding causation.

L-type amino acid transporter 1 (LAT1) plays a key role in cell growth and survival. Overexpression is a common feature of many malignancies to support increased protein synthesis demand. Among patients with multiple myeloma, high LAT1 expression has been shown to be associated higher risk disease but also a higher response rate following treatment with oral melphalan in clinical and pre-clinical models (Isoda, et al, Cancer Sci, 2014; Hathi, et al, J Nucl Med, 2018). Oral melphalan is infrequently used in today's clinical practice; however, high-dose intravenous melphalan is the standard of care for conditioning prior to ...

Salivaomics has exciting potential for the diagnosis and monitoring of malignancy, evidence of which has been reported in oral cancer, head and neck malignancies and ovarian cancer. It has been observed that approximately 40% of cancer, stroke and cardiovascular disease biomarkers are present in whole saliva. Salivaomics has become an area of great interest in disease diagnosis over the last number of years, following the footsteps of the other "omics ” based diagnostic tools. Saliva is a fast, inexpensive and non-invasive method of sample collection therefore it might be considered as the biofluid of choice for...

Hui Zhou, Xiaoyan Fu, Qian Li and Ting Niu* Department of Hematology and Research Laboratory of Hematology, West China Hospital, Sichuan University, Chengdu, China Background: Immune checkpoint inhibition therapy with monoclonal antibody against programmed cell death protein 1 (PD-1), including nivolumab and pembrolizumab, has demonstrated powerful clinical efficacy in the treatment of advanced cancers. However, there is no evidence-based systematic review on the safety and efficacy of anti-PD-1 antibody in treating lymphoma. Methods: To evaluate the safety and efficacy of nivolumab/pembrolizumab, we analyzed clin...

In this study we adopted an all-in-one method. Primers designed according to the two gRNA sequences and the tracRNA-U6 vector sequences were used to produce a gRNA1-tracRNA-U6-gRNA2 fragment. Then the proper fragment was ligated into the lentiCRISPRv2 vector and verified by sequencing. Lentiviral Packaging and Stable Cell Line Screening The constructed eukaryotic expression vector and gene knockdown vector were transfected into the 293T cells with the packaging plasmids psPAX2 and pMD2.G using Lipofectamine 2000 (Thermo Fisher, Massachusetts, USA). The lentivirus was harvested 48 h after transfection, and the lentivirus ...

In this study, we aimed to investigate the potential anti-proliferative and pro-apoptotic activities of SNG in a panel of MM cell lines (U266, IM9, MM1S, and RPMI-8226). SNG treatment of MM cells resulted in a dose-dependent decrease in cell viability through mitochondrial membrane potential loss and activation of caspase 3, 9, and cleavage of PARP. Pre-treatment of MM cells with a universal caspase inhibitor, Z-VAD-FMK, prevented SNG mediated loss of cell viability, apoptosis, and caspase activation, confirming that SNG-mediated apoptosis is caspase-dependent. The SNG-mediated apoptosis appears to be resulted from suppres...

Discussion In this section, we discuss the mechanisms responsible for lymphomagenesis in the various inborn errors of immunity and provide an overview of the treatment. Defects in Immune Responses That Predispose to Lymphomagenesis in PIDDs The complex immune mechanisms and their interplay that predisposes to neoplastic transformation of B or T cells and development of lymphomas in PIDD patients has not been fully elucidated. However, it is expected that the etiology in most cases is multifactorial and related to a dynamic regulation of immune response and environmental triggers (Figure 3). An underlying intrinsic susce...

Yi He†, Wenyong Long† and Qing Liu* Department of Neurosurgery, Xiangya Hospital, Central South University, Changsha, China Super-enhancers (SEs) refer to large clusters of enhancers that drive gene expressions. Recent data has provided novel insights in elucidating the roles of SEs in many diseases, including cancer. Many mechanisms involved in tumorigenesis and progression, ranging from internal gene mutation and rearrangement to external damage and inducement, have been demonstrated to be highly associated with SEs. Moreover, translocation, formation, deletion, or duplication of SEs themselves co...

Discussion Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in ...

In conclusion, the high structural diversity of these compounds pinpoints the significant range of inhibition strategies that can be conceived to target the class I methyltransferases. Although the structural details of the various members of this family are unique, the success stories of drug design for several enzymes belonging to this family portends the likely achievement of discovering potent and selective inhibitors of METTL3/METTL14. Author Contributions AF and AP wrote the manuscript. ZI revised and edited manuscript and prepared figures. Funding This work was supported by Associazione Italiana Ricerca sul Canc...
