This clinical trial studies the feasibility of choosing treatment based on a high throughput ex vivo drug sensitivity assay in combination with mutation analysis for patients with acute leukemia that has returned after a period of improvement or does not respond to treatment. A high throughput screening assay tests many different drugs individually or in combination that kill leukemia cells in tiny chambers at the same time. High throughput drug sensitivity assay and mutation analysis may help guide the choice most effective for an individual's acute leukemia.
I. To test patient cells in a high throughput assay against individual drugs and drug combinations within 21 days to enable optimal choice of drug combinations for therapy.
II. To test gene expression that reveals activation of druggable pathways or mutations in genes that confer susceptibility to specific agents may also be considered in choice of treatment.
I. To evaluate the response to the chosen therapy.
Leukemia cells obtained from blood or bone marrow are analyzed for sensitivity to both individual drugs and drug combinations via high throughput chemotherapy sensitivity assay and next generation sequencing assays. Doctors will then recommend chemotherapy regimens based on the results.
After completion of the chemotherapy regimen, patients are followed up at 2-4 weeks for response, and then every 3 months for 2 years for duration of response and survival.

Essential thrombocytosis (ET) is a chronic myeloproliferative neoplasm characterized by the presence of thrombocytosis and it can be complicated by thrombotic and/or hemorrhagic events. Treatment opti...
Previous studies have suggested that urine cytology adequacy may be related to both specimen volume and cellularity.
In order to increase the detection rate of pathogenic microorganisms in CSF, an improved specimen handling procedure (ISHP) was created.
Today's state-of-the-art cell sorting flow cytometers are equipped with aerosol containment systems designed to evacuate aerosols from the sort chamber during a sort. This biosafety device is especial...
Enzymes that catalyze DNA template-directed extension of the 3'-end of an RNA strand one nucleotide at a time. They can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to alpha-amanitin, and the type of RNA synthesized. (From Enzyme Nomenclature, 1992).
An isothermal in-vitro nucleotide amplification process. The process involves the concomitant action of a RNA-DIRECTED DNA POLYMERASE, a ribonuclease (RIBONUCLEASES), and DNA-DIRECTED RNA POLYMERASES to synthesize large quantities of sequence-specific RNA and DNA molecules.
Drug treatment designed to further diminish the disease toward complete remission following INDUCTION CHEMOTHERAPY. It helps to consolidate the gains during induction chemotherapy and may be followed by MAINTENANCE CHEMOTHERAPY.
Development of a library collection, including the determination and coordination of selection policy, assessment of needs of users and potential users, collection use studies, collection evaluation, identification of collection needs, selection of materials, planning for resource sharing, collection maintenance and weeding, and budgeting.
Cell lines whose original growing procedure consisted being transferred (T) every 3 days and plated at 300,000 cells per plate (J Cell Biol 17:299-313, 1963). Lines have been developed using several different strains of mice. Tissues are usually fibroblasts derived from mouse embryos but other types and sources have been developed as well. The 3T3 lines are valuable in vitro host systems for oncogenic virus transformation studies, since 3T3 cells possess a high sensitivity to CONTACT INHIBITION.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
