Early Clinical Trial Data Show Gene Therapy Reversing Sickle Cell Anemia

After over a decade of preclinical research and development, a new gene therapy treatment for Sickle Cell Anemia (SCA) is reversing disease symptoms in two adults and showing early potential for transportability to resource-challenged parts of the world where SCA is most common.  Preliminary data from a pilot Phase 1-2 clinical trial testing the gene-addition therapy were presented Dec. 3 at the American Society of Hematology’s (ASH) annual meeting in San

Johns Hopkins Researchers Advance Role of Circulating Tumor DNA to Detect Early Melanoma Growth, Uncover Treatment Options

Researchers at the Johns Hopkins Kimmel Cancer Center say they have added to evidence that measuring and monitoring tumor DNA that naturally circulates in the blood of melanoma patients can not only reliably help reveal the early stages of cancer growth and spread but also uncover new treatment options that tumor genetic analysis alone may not. “For some patients in our study, ctDNA (circulating tumor DNA) levels measured in a relatively simple

Enzyme Discovery Points Researchers Toward Starving Lung Cancer as a Potential Treatment

 UT Southwestern researchers have found that an enzyme on the surface of some lung cancer cells helps feed the cancer, making it a tempting treatment target. The enzyme, transmembrane serine protease 11B (TMPRSS11B) is described in a report published today in the journal Cell Reports. In addition to being found in squamous cell lung cancer and prostate cancer, the enzyme also has been identified in squamous cell head, neck, and cervical cancers,

A study suggests that epigenetic treatments could trigger the development of aggressive tumours

Cancer develops as a result of the accumulation of mutations in our cells. These mutations are not distributed evenly in our chromosomes, so some regions hold more than others. A study headed by the Institute for Research in Biomedicine (IRB Barcelona) and published in the journal Nature Cell Biologyexamined whether the opening of chromatin (a complex formed by DNA bound to proteins) is the factor that determines the accumulation of more

Researchers stop ‘sneaky’ cancer cells in their tracks

A new study by University of Minnesota biomedical engineers shows how they stopped cancer cells from moving and spreading, even when the cells changed their movements. The discovery could have a major impact on millions of people undergoing therapies to prevent the spread of cancer within the body. The research is published today in Nature Communications, a leading research journal. Researchers have known for years that tumors have patterns that are like

Investigational Drug Shows Promising Results in Phase II Study of Aggressive, Often Fatal Blood Disorder with No Approved Therapies

A Phase I/II study, led by investigators at The University of Texas MD Anderson Cancer Center, reports an investigational drug called tagraxofusp has demonstrated high response rates in patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN), a rare but highly aggressive – and often fatal bone marrow and blood disorder – for which there are no existing approved therapies. Findings from the study are being presented Dec. 3 at the 60th American Society of

Immunotherapy combination and chemotherapy show encouraging results in Phase II acute myeloid leukemia study

 A triple therapy combining two immune checkpoint inhibitors (ICPIs) with the standard-of-care chemotherapy, a hypomethylating agent called azacitidine, has shown promising results for treatment of relapsed or refractory acute myeloid leukemia (AML), according to findings from a Phase II study at The University of Texas MD Anderson Cancer Center. Findings from the study, led by Naval Daver, M.D., associate professor of Leukemia, are being presented at the 60th American Society of Hematology Annual Meeting & Exposition in San Diego. The

Spread of Deadly Eye Cancer Halted in Cells and Animals

 By comparing genetic sequences in the eye tumors of children whose cancers spread with tumors that didn’t spread, Johns Hopkins Medicine researchers report new evidence that a domino effect in cells is responsible for the cancer spreading. Their experiments suggest that blocking part of the chain of events — which they successfully accomplished in zebra fish and human cells — stops the growth and spread of the eye tumor cells.

A New Tool to Help Fight an Old Enemy – Lung Cancer

November is Lung Cancer Awareness Month and in the United States, lung cancer remains the leading cause of cancer death among both men and women. The primary reason for high death rates for lung cancer is the fact that this disease is typically detected in very late stages, when treatment is often of little use. In 2011, the National Lung Cancer Screening Trial demonstrated that high-risk smokers who received a

New radiotherapy treatment for brain cancer offers superior preservation of cognitive function, Mayo researchers say

 When it comes to radiation therapy to treat brain cancer, hippocampal-avoidance whole-brain radiotherapy in conjunction with the drug memantine better preserved patients’ cognitive function and demonstrated similar cancer control outcomes, compared to traditional whole-brain radiotherapy with memantine. These findings were presented on Tuesday, Oct. 23, by Mayo Clinic researchers at the 2018 annual meetingof the American Society for Radiation Oncology (ASTRO) in San Antonio. “The hippocampus is a part of the brain associated with the

Researchers Identify a New Way to Determine Whether Metastatic Cancer Cells in Breast Cancer Patients are Dormant or Soon to Turn Deadly

For the first time ever, Mount Sinai researchers have identified a protein as a marker that can indicate whether a cancer patient will develop a reoccurrence of lethal, metastatic cancer, according to a clinical study published in Breast Cancer Research in October. The researchers found that when cells from a breast cancer patient’s original tumor metastasized into the patient’s bone marrow with none, or only a small amount, of the protein NR2F1,

New Study Finds Nanoparticles Show Promise in Therapy for Triple-Negative Breast Cancer

Approximately 10-20 percent of diagnosed breast cancers are found to be triple-negative, meaning the breast cancer cells test negative for estrogen and progesterone receptors as well as HER2 receptors, genes that can play a role in the development of breast cancer. Triple-negative breast cancer can be more aggressive and difficult to treat as the cancer cells do not respond to hormonal therapies or therapies that target HER2 receptors. A new

Doctor-patient discussions neglect potential harms of lung cancer screening, study finds

Although national guidelines advise doctors to discuss the benefits and harms of lung cancer screening with high-risk patients because of a high rate of false positives and other factors, those conversations aren't happening the way they should be, according to a study by researchers from the University of North Carolina Lineberger Comprehensive Cancer Center. Lung cancer screening is recommended for high-risk current and former smokers, but because of the potential
