Leukemia News and Research

RSS

Leukemia (Leukaemia) is a cancer of the blood cells. It is the most common type of blood cancer and affects 10 times as many adults as children. Most people diagnosed with leukemia are over 50 years old. No one knows why some people develop leukemia and others do not. However, scientists have identified some risk factors for the disease. Most people who have known risk factors do not get leukemia, while many who do get the disease have none of these risk factors. During the early stages of leukemia, there may be no symptoms. Many of the symptoms of leukemia don't become apparent until a large number of normal blood cells are crowded out by leukemia cells.

Vaccine that boosts the immune response could improve the effect of conventional treatment for patients with chronic myeloid leukaemia

CML is caused by the breakage and swapping of chromosomes 9 and 22, which results in a shortened chromosome called the Philadelphia chromosome. Cells with the abnormal chromosome make a protein that encourages aberrant growth and division. Patients with CML can be treated with a drug called imatinib or interferon alfa.

Exposure of expectant mothers to urban air pollution may alter the structure of babies' chromosomes while in the womb

A new study of 60 newborns in New York City reveals that exposure of expectant mothers to combustion-related urban air pollution may alter the structure of babies' chromosomes while in the womb.

New compound AMN107 may help treat some imatinib resistant cancer cases

As scientists uncover the precise molecular mechanisms that underlie effective cancer treatments, they gain invaluable insight into why predominantly successful treatments fail for some patients.

Experimental drug Revlimid showing promise as treatment for myelodysplastic syndrome (MDS)

Alan List, M.D., leader of the Hematologic Malignancies Program at the H. Lee Moffitt Cancer Center & Research Institute, recently conducted a phase I/II trial of the experimental drug Revlimid showing promise as an innovative way to treat patients with myelodysplastic syndrome (MDS), a form of pre-leukemia.

Artemisinin could selectively kill cancer cells while leaving normal cells unharmed

Researchers at the University of Washington have blended the past with the present in the fight against cancer, synthesizing a promising new compound from an ancient Chinese remedy that uses cancer cells' rapacious appetite for iron to make them a target.

Level of immune cell DNA in the blood might help predict success of stem cell transplantation

Measuring the quantity of a certain type of immune cell DNA in the blood could help physicians predict whether a bone marrow stem cell transplant will successfully restore a population of infection-fighting cells called T lymphocytes in a child.

Cell research signals cancer hope

Scientists have moved a step closer to understanding what happens when cells receive a faulty signal that is known to be a cause of cancer.

Gene used in brain development can cause childhood brain cancers

A gene that's normally silenced after contributing to brain development was found to be expressed in cells from medulloblastoma, the most common form of pediatric brain malignancy in children, scientists report in an article published in the February 1 issue of the journal Cancer Research.

Compound, derived from a rare South American plant, stops the growth of human breast cancer cells

They started with a bare room and an idea. Now, after five years of painstaking, sophisticated tests, scientists at the University of Virginia Health System have discovered that a compound, derived from a rare South American plant, stops the growth of human breast cancer cells in laboratory cultures.

Eleventh Edition of the Report on Carcinogens

The Department of Health and Human Services released its Eleventh Edition of the Report on Carcinogens today, adding seventeen substances to the growing list of cancer-causing agents, bringing the total to 246.

Why some men develop aggressive prostate cancer that becomes resistant to hormone-withdrawal therapy

Researchers found that certain mutations in a protein called the androgen receptor cause advanced and invasive prostate cancer when put into otherwise healthy mice. The androgen receptor's normal function is to control growth of the prostate gland in response to cues from male hormones called androgens, which have long been thought to stimulate prostate tumors.

Research may provide the basis for development of a new, extensive immunotherapy for human tumors

Scientists have made significant progress towards understanding how the immune system can be more specifically and efficiently targeted against cancer cells. The research, published in the January issue of Immunity, may provide the basis for development of a new, extensive immunotherapy for human tumors.

New highly active agents against leishmaniasis

Parasitic diseases, especially leishmaniases and trypanosomiases, kill hundreds of thousands of people every year in the world, mainly in the countries of the South. The most severe form of leishmaniosis (kala-azar, the visceral form), induced by Leishmania donovani and L. infantum, affects about 500 000 people per year and proves fatal if no treatment is given.

New blood tests to soon replace painful bone marrow biopsies for leukemia and lymphoma patients

Quest Diagnostics Incorporated announced today that The University of Texas M. D. Anderson Cancer Center in Houston has granted the company exclusive use of five proprietary blood testing methods, which, once available in the form of laboratory diagnostic tests, may eliminate the need for painful and expensive bone marrow and other tissue extractions.

Cord blood transplantation now a viable option for adult leukemia patients

Stem cell transplantation using umbilical cord blood is a standard treatment option for blood disorders in children, but not for adults, due to the difficulty of obtaining a sufficiently large dose of cells.

FDA knocks back anticancer drug Marqibo

Inex Pharmaceuticals announced today that United States Food and Drug Administration (FDA) provided an action letter detailing that the anticancer drug Marqibo (vincristine sulfate liposomes injection) is "not approvable" under the FDA's accelerated approval regulations based on the phase 2 clinical trial data submitted.

Prenatal exposure to industrial and environmental pollutants probably causes most childhood cancers

Most childhood cancers are "probably" down to prenatal exposure to industrial and environmental pollutants, most likely to have been inhaled by the mother during pregnancy, suggests research in the Journal of Epidemiology and Community Health.

Researchers to test new leukemia drug

Chronic myeloid leukemia (CML) is a malignant cancer of the blood that affects people of all ages. While treatment is available for most of these patients, approximately 20 percent of them do not respond to it. Researchers at McGill teaching hospitals will soon study the effects of a new alternative therapy.

Glia cells may be essential for the normal development of nerve cells responsible for hearing and balance

Traditionally viewed as supporting actors, cells known as glia may be essential for the normal development of nerve cells responsible for hearing and balance, according to new University of Utah research. The study is reported in the January 6, 2005 issue of Neuron and is co-authored by scientists at the University of Washington.
