BACKGROUND: Fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD)-positive acute myeloid leukaemia (AML) relapsing after allogeneic stem cell transplantation (allo-SCT) has a dismal prognosis with limited therapeutic options. FLT3-ITD kinase inhibition is a reasonable but palliative experimental treatment alternative in this situation. Information on long-term outcome is not available. METHODS: We performed a long-term follow-up analysis of a previously reported cohort of 29 FLT3-ITD-positive AML patients, which were treated in relapse after allo-SCT with sorafenib monotherapy...

BACKGROUND: Low activity of natural killer (NK) cells is known to be associated with higher risk of cancer, especially with poor prognosis and the presence of colorectal cancer (CRC). We investigated whether NK cells activity differs between subjects with and without colorectal neoplasia (CRN). METHODS: A cross-sectional study was performed on 1818 asymptomatic examinees aged ≥30 years who underwent NK cell activity test (which quantitates the amount of interferon-γ secreted into the plasma by NK cells) and a colonoscopy as part of a health check-up...

Mutations in the RUNX1 gene have been associated with chemotherapy resistance and poor prognosis in patients with acute myeloid leukemia (AML), T cell acute lymphoblastic leukemia (T-ALL) and myelodysplastic syndromes (MDS). However, the underlying mechanisms connecting RUNX1 to the success of therapy remain elusive. Here we explore the hypothesis that RUNX1 is directly involved in the response of hematopoietic cells to cytotoxic agents. RUNX1 was upregulated post-transcriptionally by cytotoxic agents in C57BL/6 mice in vivo and hematopoietic cell lines...

Overexpression and activation of the Epidermal Growth Factor Receptor (EGFR) have been linked to poor prognosis in several human cancers. Cetuximab is a monoclonal antibody against EGFR, that is used for the treatment in head and neck squamous cell carcinoma (HNSCC) and metastatic colorectal cancer. Unfortunately, most tumors have intrinsic or acquire resistance to cetuximab during the course of therapy. Honokiol is a natural compound found in the bark and leaves of the Chinese Magnolia tree and is established to have several anti-cancer properties without appreciable toxicity...

Breast cancer is the most frequent cancer in women worldwide. It is classified into intrinsic subtypes characterized by different molecular profiles and prognosis. The prevalence of the different intrinsic subtypes varies between population groups. Immunohistochemistry surrogates based on the expression of the estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) have been widely used to study the distribution of intrinsic subtypes in Non-Hispanic Whites and African Americans, but data is limited for Hispanic/Latina women...

A recent study indicated that high Wnt5a expression is associated with poor prognosis in NSCLC patients, however, the underlying mechanism was not clear yet. Immunohistochemistry and Western blotting was performed to examine the protein expression level in NSCLC tissues and cell lines. The role of Wnt5a in clone formation, invasiveness, migration and epithelial-to-mesenchymal transition (EMT) of NSCLC cells were studied. Luciferase reporter assay was used to evaluate the Tcf/Lef transcriptional activity. For assessing the effects of Wnt5a on tumor growth and metastasis in vivo , A549 cells transfected with sh-Wnt5a were subcutaneously or orthotopically injected into nude mice...

Acquired tumor resistance to cancer therapies pose major challenges in the treatment of cancers including melanoma. Among several signaling pathways or factors that affect neocarcinogenesis, cancer progression and therapies, altered microRNAs (miRNAs) expression has been identified as crucial players in modulating the key pathways governing these events. While studies on miRNA field has grown exponentially in the last decade, much remains to be discovered, particularly with respect to their roles in cancer therapies...

BACKGROUND: Current American Heart Association/American College of Cardiology guidelines recommend the GRACE (Global Registry of Acute Coronary Events) and TIMI (Thrombolysis in Myocardial Infarction) scores to assess myocardial infarction (MI) prognosis. Changes in the epidemiological characteristics of MI and the availability of new biomarkers warrant an assessment of the performance of these scores in contemporary practice. We assessed the following: (1) the performance of GRACE and TIMI to predict 1-year mortality in a cohort of patients stratified by ST-segment elevation MI (STEMI) and non-STEMI (NSTEMI) and (2) the incremental discriminatory power of soluble suppression of tumorigenicity-2, a myocardial fibrosis biomarker...

Primary or secondary diaphragmatic echinococcosis is rare, accounting for 1% of the thoracic locations. They may be operative discovery or by their complication, hence a variable symptomatology making this localization a particular entity. The thoracic and abdominal CT allows a complete assessment. Surgery remains the only therapeutic approach. In complicated forms an additional surgery is required for complete care. The prognosis is generally good apart from the risk of recurrence. Through a series of 4 operated patients, we focus on the clinical and therapeutic features of this pathology and its complications...

Epithelial ovarian cancer (EOC) is a heterogeneous disease with a major heritable component. The different histotypes of invasive disease - high grade serous, clear cell, endometrioid and mucinous - are associated with different underlying genetic susceptibility and epidemiological and lifestyle risk factors, all of which contribute to the different biology and clinical characteristics of each histotype. A combination of familial and population based sequencing studies, and genome wide association studies (GWAS) have identified a range of genetic susceptibility alleles for EOC comprising rare but highly penetrant genes (e...

Msi2 has been widely reported to be upregulated and strongly associated with fast progress and poor prognosis in many cancers. However, the expression and role of Msi2 in esophageal squamous cell carcinoma (ESCC) remain unknown. In this study, we found that Msi2 was upregulated in ESCC clinical samples, and was significantly associated with tumor size, differentiation status, and lymph node metastasis in ESCC patients. Multivariate Cox regression analysis showed that Msi2 was an independent predictor for disease-free survival (DFS) and overall survival (OS)...

Malignant gliomas are glial-derived, primary brain tumors that carry poor prognosis. Existing therapeutics are largely ineffective and dramatically affect quality of life. The standard of care details a taxing combination of surgical resection, radiation of the resection cavity, and temozolomide (TMZ) chemotherapy, with treatment extending life by only an average of months (Maher et al., 2001; Stupp et al., 2005). Despite scientific and technological advancement, surgery remains the most important treatment modality...

Tumor cell can be significantly influenced by various chemical groups of the extracellular matrix proteins. However, the underlying molecular mechanisms involved in the interaction between cancer cells and functional groups in the extracellular matrix remain unknown. Using chemically modified surfaces with biological functional groups (CH3, NH2, OH), it was found that hydrophobic surfaces modified with CH3 and NH2 suppressed cell proliferation and induced the number of apoptotic cells. Mitochondrial dysfunction, cytochrome c release, Bax upregulation, cleaved caspase-3 and PARP, and Bcl-2 downregulation indicated that hydrophobic surfaces with CH3 and NH2 triggered the activation of intrinsic apoptotic signaling pathway...

BACKGROUND: The uncontrolled inflammatory response following infection is closely related to the morbidity and mortality of neonates. Interleukin 6 (IL-6) plays an important role in the pathogenesis and prognosis of this process. To better elucidate the secretion of IL-6 following infection in neonates, we investigated the IL-6 level and mechanism of IL-6/TLR4 signaling pathways. METHODS: We compared the IL-6, procalcitonin (PCT), and CRP levels between septic neonates and toddlers...

BACKGROUND: The Body mass index, Obstruction, Dyspnea, and Exercise capacity (BODE) score is used to inform prognostic considerations for lung transplantation for chronic obstructive pulmonary disease (COPD), but it has not been validated in this context. A large proportion of mortality in COPD is attributable to comorbidities that could preclude transplant candidacy. We hypothesized COPD patients selected as transplant candidates experience better survival than traditional interpretation of BODE scores might indicate...
