NEW ORLEANS – A panel of the Fifth Circuit U.S. Court of Appeals on June 14 issued a mandate affirming the ruling of a district court, which determined that a plaintiff’s expert was unreliable in reaching the conclusion that exposure to gasoline containing benzene can cause acute myeloid leukemia (AML) (Yolande Burst v. Shell Oil Company, et al., No. 15-30592, 5th Cir.).

ConclusionOur study confirms the high prevalence of AML in elderly patients with generally poor outcomes. Selected patients with a good performance status and those who received intensive induction treatment could have a long-term survival.

This randomized, open-label, phase 2b study (NCT01565668) evaluated the efficacy and safety of 2 dosing regimens of quizartinib monotherapy in patients with relapsed/refractory (R/R) FLT3-internal tandem duplication (ITD)–mutated acute myeloid leukemia (AML) who previously underwent transplant or 1 second-line salvage therapy. Patients (N = 76) were randomly assigned to 30- or 60-mg/day doses (escalations to 60 or 90 mg/day, respectively, permitted for lack/loss of response) of single-agent oral quizartinib dihydrochloride. Allelic frequency of at least 10% was defined as FLT3-ITD–mutated disease. Coprimary end…

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…

UCLA Health has joined an important national clinical trial that uses genetic testing to match people who have acute myeloid leukemia, or AML, with new therapies. UCLA ’s hospital system is the first in California to offer people the opportunity to participate.The Beat AML Master Trial will evaluate a precision-based medicine approach to treating the disease; it will allow people with the disease to have immediate access to new treatments that are currently in development without having to try more traditional approaches first. The approach could streamline a patient ’s course of treatment and, ultimately, save…

Standard therapy or improving standard therapy can make the majority of acute myeloid leukemia (AML) patients partly or complete remission. However, the treatment often relapses from remission. A small fraction of leukemic stem cells (LSCs) are responsible for the accumulation of immature malignant cells in the bone marrow. LSCs were considered the ‘bad seeds’, it was showed that AML patients with LSCs enrichment have worse clinical outcomes [1]. Therefore, targeting LSCs by candidate drugs is crucial for AML therapies.

To enable the characterization of genetic heterogeneity in tumor cell populations, we developed a novel microfluidic approach that barcodes amplified genomic DNA from thousands of individual cancer cells confined to droplets. The barcodes are then used to reassemble the genetic profiles of cells from next-generation sequencing data. By using this approach, we sequenced longitudinally collected acute myeloid leukemia (AML) tumor populations from two patients and genotyped up to 62 disease relevant loci across more than 16,000 individual cells. Targeted single-cell sequencing was able to sensitively identify cells harboring …
