In the past, increases in childhood cancer incidence were reported in Europe and North America. The aim of this study is to show updated patterns of temporal behavior using data of the Childhood Cancer Registry of Piedmont (CCRP), a region with approximately 4.5 million inhabitants in North-West Italy. CCRP has been recording incident cases in children (0-14 years) since 1967 and in adolescents (15-19) since 2000. Time trends were estimated as annual percent change (APC) over the 1976-2011 period for children, and over 2000-2011 for both children and adolescents...

Polycomb repressive complex 2 (PRC2) methylates histone H3 lysine 27 and represses gene expression to regulate cell proliferation and differentiation. Enhancer of zeste homolog 2 (EZH2) or its close homolog EZH1 function as catalytic subunits of PRC2, so there are two PRC2 complexes containing either EZH2 or EZH1. Tumorigenic functions of EZH2 and its synthetic lethality with some subunits of SWItch/Sucrose Non-Fermentable (SWI/SNF) chromatin remodeling complexes have been observed. However, little is known about the function of EZH1 in tumorigenesis...

Mutations that impair apoptosis contribute to cancer development and reduce the effectiveness of conventional anti-cancer therapies. These insights and understanding of how the B cell lymphoma (BCL)-2 protein family governs apoptosis have galvanized the search for a new class of cancer drugs that target its pro-survival members by mimicking their natural antagonists, the BCL-2 homology (BH)3-only proteins. Successful initial clinical trials of the BH3 mimetic venetoclax/ABT-199, specific for BCL-2, have led to its recent licensing for refractory chronic lymphocytic leukemia and to multiple ongoing trials for other malignancies...

Redirected T cells genetically modified with a chimeric antigen receptor (CAR) induced spectacular remissions of so far refractory leukemia/lymphoma in early phase trials attracting interest to use CAR T cells in a variety of other applications including solid cancer and non-malignant diseases. However, extensive pre-clinical explorations demand highly effective and robust procedures for the genetic modification of blood T cells; the same applies for engineering with a recombinant T cell receptor (TCR). We present laboratory procedures in a step-by-step protocol to engineer human and mouse T cells with a CAR by retro- or lentiviral transduction for further pre-clinical testing...

Cancer has become one of the leading causes of morbidity and mortality worldwide. Limitations associated with existing agents increase the need to develop more effective anticancer drugs to improve the therapeutic arsenal available. Here, we describe the synthesis, characterization, toxicity and selectivity in vitro of three novel thiazacridine derivatives (ATZD): (Z)-5-acridin-9-ylmethylene-3-(4-methyl-benzyl)-4-thioxo-thiazolidin-2-one (LPSF/AC-99), (Z)-5-acridin-9-ylmethylene-3-(4-chloro-benzyl)-4-thioxo-thiazolidin-2-one (LPSF/AC-119) and (Z)-5-acridin-9-ylmethylene-3-(3-chloro-benzyl)-4-thioxo-thiazolidin-2-one (LPSF/AC-129)...

Silibinin (silybin), a non-toxic natural polyphenolic flavonoid, is the principal and the most biologically active component of silymarin. It is efficient in the treatment of acute and chronic liver disorders caused by toxins, drug, alcohol, hepatitis, and gall bladder disorders. Further, in our previous studies, we explored the anti-cancer efficacy in common cancers, such as lung, prostatic, colon, breast, bladder, as well as, hepatocellular carcinoma. Interestingly, silibinin is still not solely limited to the treatment of these diseases...

Infection by the Human T- Lymphotropic virus I (HTLV-1) causes Adult T cell Leukemia-lymphoma (ATLL), being the duodenal involvement rare. Commonly, patients co-infected with HTLV-1 and Strongyloides stercoralis are seen due to the lack of TH2 response found on these patients. We describe a 48-year- old woman, from the jungle of Peru, with a family history of HTLV-1 infection, who presented with a History of chronic diarrhea and weight loss. HTLV-1 infection with ATLL and strongyloidiasis were diagnosed. Ivermectin treatment and chemotherapy were initiated, being stabilized, and discharged...

BACKGROUND: Despite the importance of estimating population level cancer outcomes, most registries do not collect critical events such as relapse. Attempts to use health administrative data to identify these events have focused on older adults and have been mostly unsuccessful. We developed and tested administrative data-based algorithms in a population-based cohort of adolescents and young adults with cancer. METHODS: We identified all Ontario adolescents and young adults 15-21 years old diagnosed with leukemia, lymphoma, sarcoma, or testicular cancer between 1992-2012...

The present study was carried out to determine whether the mechanically activated cation channel Piezo1 protein plays a role as a signaling pathway which causes the apoptosis of human chondrocytes. The chondrocytes were isolated, cultured, and then subjected to mechanical stretch force for 0, 2, 12, 24 and 48 h, respectively. The expression levels of Piezo1 and the apoptosis-related protein caspase-12 were assessed by reverse transcription-quantitative polymerase chain reaction, as well as the apoptosis-related genes, B cell lymphoma/leukemia-2 (Bcl-2), Bcl-associated X protein (Bax) and Bcl-2-associated death promoter (BAD)...

Dendritic cells (DCs) orchestrate immune responses after allogeneic hematopoietic cell transplantation (HCT). We studied the association of donor myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) recovery in the landmark analysis of umbilical cord blood (UCB) and matched related donor (RD) HCT. Eighty patients (42 UCB and 38 RD recipients) with a day 100 (D+100) blood sample were included in the analysis. Median age was 51 years (20-71). Most patients had acute leukemia (50%) or lymphoma (23%) and received reduced-intensity conditioning (75%)...

We developed a GMP-compatible expansion protocol, to improve number and purity of Tregs available for clinical trials. Six clinical grade separation procedures were performed, followed by expansion with high-dose interleukin (IL)-2, anti-CD3/anti-CD28 TCR stimulation and rapamycin for 19 days achieving a median of 8.5 fold (6.25-13.7) expansion. FOXP3 expression was stably maintained over the culture period, while the percentage of CD127 was significantly reduced. The in vitro suppression assay showed a strong MLR inhibition...

Proviral insertion in murine (PIM) lymphoma proteins are mainly regulated by the Janus Kinase/Signal Transducer Activator of Transcription (JAK/STAT) signaling pathway, which can be activated by members of the Interleukin-6 (IL-6) family, including Leukemia Inhibitory Factor (LIF). Aim of the study was to compare PIM1, PIM2 and PIM3 expression and potential cellular functions in human first and third trimester trophoblast cells, the immortalized first trimester extravillous trophoblast cell line HTR8/SVneo and the choriocarcinoma cell line JEG-3...

As long-term survival is high for children and young adults diagnosed with leukemia and lymphoma, delineating maternal, fetal and offspring health risks is important to their family planning. This systematic review examined data comparing these health risks between leukemia and lymphoma survivors and women without a history of cancer. Following a search of Embase, PubMed, CINAHL, Cochrane, and Web of Science, 142 articles were screened and 18 were included in this review. No higher risks of spontaneous abortion, maternal diabetes and anemia, stillbirth, birth defects, or childhood cancer in offspring were observed in survivors compared to controls...

Chimeric antigen receptors (CARs) have been used to redirect the specificity of autologous T-cells against leukemia and lymphoma with promising clinical results.(1-3) Extending this approach to allogeneic T-cells is problematic as they carry a significant risk of graft-versus-host disease (GVHD). Natural killer (NK) cells are highly cytotoxic effectors, killing their targets in a non-antigen specific manner without causing GVHD. Cord blood (CB) offers an attractive, allogeneic, off-the-self source of NK cells for immunotherapy...

We previously reported that the T-cell receptor (TCR) repertoire of HTLV-I Tax301-309-specific CD8(+) cytotoxic T-cells (Tax-CTLs) was highly restricted and a particular amino acid sequence motif, "PDR", was conserved among HLA-A*24:02(+) ATL patients who have undergone allogeneic hematopoietic cell transplantation (allo-HSCT). Furthermore, we found that donor-derived PDR+CTLs selectively expanded in ATL long-term HSCT survivors with strong CTL activity against HTLV-I. On the other hand, the TCR repertoires in Tax-CTL of asymptomatic HTLV-I carriers (ACs) remain unclear...

The B-cell leukemia/lymphoma-2 (BCL-2) family of proteins governs the intrinsic pathway of mitochondrial apoptosis. Dysregulation of BCL-2 has long been known to be a crucial part of the pathophysiology of B-cell lymphomas, yet several early attempts to target this pathway therapeutically were unsuccessful due to toxicity, lack of efficacy, or both. Recently, a highly potent and selective oral BCL-2 antagonist, venetoclax, was approved in chronic lymphocytic leukemia (CLL), where it has proven to be highly active, even in patients with high risk del(17p) disease...

Racial and ethnic disparities in patients with solid malignancies have been well documented. Less is known about these disparities in patients with hematologic malignancies. With the advent of novel chemotherapeutics and targeted molecular, cellular, and immunologic therapies, it is important to identify differences in care that may lead to disparate outcomes. This review provides a critical appraisal of the empirical research on racial and ethnic disparities in incidence, survival, and outcomes in patients with hematologic malignancies...

The switch of pyruvate kinase (PK) M1 to PKM2 is pivotal for glucose metabolism in cancers. The PKM1/M2 shift is controlled by the alternative splicing of two mutually exclusive exons in the PKM gene. PKM1 is expressed in differentiated tissues, whereas PKM2 is expressed in cancer tissues. This study revealed that the haplodeficiency of FUSE-binding protein (FBP)-interacting repressor (FIR), a transcriptional repressor of the c-myc gene, contributed to the splicing of PKM1 to PKM2 in mice thymic lymphoma and/or T-cell type acute lymphoblastic leukemia (T-ALL) using six-plex tandem mass tag (TMT) quantitative proteomic analysis...
