Because it is impossible to predict which acute myeloid leukaemia (AML) patients will benefit, all patients are routinely treated with chemotherapy although only some will respond to the treatment. Researchers have now discovered a novel biomarker that enables the detection of therapy responders and non-responders with high accuracy. In addition, their research reveals new hope for patients who currently cannot be effectively treated.

Abstract
INTRODUCTION: Acute myeloid leukemia (AML) is the most common myeloid malignancy in adults. Despite recent discoveries of targeted therapies, the frontline therapy consisting of chemotherapy remains unchanged for the past four decades. Like other cancers, AML is characterized by deranged DNA damage repair (DDR) pathway. Although impaired DDR may contribute to the pathogenesis of AML it also allows leukemia cells with damaged DNA to attempt repair resulting in resistance. CHK1 inhibitors reverse the cell cycle arrest, disallowing the cell to repair the chemotherapy-induced DN…

Selective destruction of senescent cells in old tissues offers the promise of some degree of rejuvenation, coupled with effective therapies for a range of age-related diseases that currently cannot be controlled. In the past few years, a number of companies have raised venture funding for the development of senolytic therapies, those capable of removing some portion of senescent cells with an acceptable side-effect profile. The potential market is enormous, and thus despite the many potential competitors, any new mechanism by which senescent cells can be destroyed might be the pathway to success and revenue for the individ…

In conclusion, incidence of breakthrough IFI was low among patients receiving posaconazole prophylaxis, and not significantly different between patients receiving the tablet versus oral suspension formulations.

We presently forget 98% of everything we experience. That will go away in favor of perfect, controllable, configurable memory. Skills and knowledge will become commodities that can be purchased and installed. We will be able to feel exactly as we wish to feel at any given time. How we perceive the world will be mutable and subject to choice. How we think, the very fundamental basis of the mind, will also be mutable and subject to choice. We will merge with our machines, as Kurzweil puts it. The boundary between mind and computing device, between the individual and his or her tools, will blur.

Therapy related myeloid neoplasm (t-MN) is an emerging challenge in the current era given that newer therapies are improving the life expectancy of patients diagnosed with cancer. This condition arises as a result of exposure to prior chemotherapy or radiotherapy used to treat malignant or non-malignant conditions. The World Health Organization (WHO) 2001 classification of tumors of hematopoietic and lymphoid tissues had initially described this disorder with two subtypes – therapy related acute myeloid leukemia (t-AML) and therapy related myelodysplastic syndrome (t-MDS) 1.

Mutations in receptor tyrosine kinase/RAS signaling pathway genes are frequent in core-binding factor (CBF) acute myeloid leukemias (AMLs), but their prognostic relevance is debated. A subset of CBF AML patients harbors several signaling gene mutations. Genotyping of colonies and of relapse samples indicates that these arise in independent clones, thus defining a process of clonal interference (or parallel evolution). Clonal interference is pervasive in cancers, but the mechanisms underlying this process remain unclear, and its prognostic impact remains unknown. We analyzed a cohort of 445 adult and pediatric patients with…

Publication date: Available online 9 November 2017Source: Seminars in Cancer BiologyAuthor(s): Christian Flotho, Sebastian Sommer, Michael LübbertAbstractMyelodysplastic syndrome (MDS) is a clonal bone marrow disorder, typically of older adults, which is characterized by ineffective hematopoiesis, peripheral blood cytopenias and risk of progression to acute myeloid leukemia. Juvenile myelomonocytic leukemia (JMML) is an aggressive myeloproliferative neoplasm occurring in young children. The common denominator of these malignant myeloid disorders is the limited benefit of conventional chemotherapy and a particular resp…

CONCLUSIONS: Collectively, our data suggest that an anti-CLL-1-ADC has the potential to become an effective and safer treatment for AML in humans, by reducing and allowing for faster recovery from initial cytopenias than the current generation of ADCs for AML.

Minimal (or measurable) residual (MRD) disease provides a biomarker of response quality for which there is robust validation in the context of modern intensive treatment for younger patients with Acute Myeloid Leukemia (AML). Nevertheless, it remains a relatively unexplored area in older patients with AML. The lack of progress in this field can be attributed to two main reasons. First, physicians have a general reluctance to submitting older adults to intensive chemotherapy due to their frailty and to the unfavourable biological disease profile predicting a poor outcome following conventional chemotherapy. Seco…

Mutations or other alterations in theRET gene have been implicated in a variety of malignancies – most commonly thyroid, but also chronic myelomonocytic leukemia, acute myeloid leukemia, and lung, breast, pancreatic, and colon cancers. Here we present a case of a gentlemen initially diagnosed with and treated for non-small cell lung adenocarcinoma. Genomic profiling of his tumor specimen rev ealed aRET point mutation with a known association with medullary thyroid cancer (MTC). Further pathological and molecular diagnostic evaluation confirmed a diagnosis of MTC, leading to a change in treatment from standard chemoth…
