Women with atypical hyperplasia are at higher risk of breast cancer

Atypical hyperplasia of the breast is a precancerous condition found in about one-tenth of the over 1 million breast biopsies with benign findings performed annually in the United States. Viewed under a microscope, atypia contains breast cells that are beginning to grow out of control (hyperplasia) and cluster into abnormal patterns (atypical)…

Lung cancer metastases may travel through airways to adjacent or distant lung tissue

Lung cancer is the most common and most lethal cancer worldwide. Its prognosis remains poor: The 5-year survival rate is 6-18%. Adenocarcinoma has surpassed squamous cell carcinoma as the leading histologic type, accounting for 30% of all cases of lung cancer. Hematogenous spread (i.e., carried by blood) is the most common mechanism of intrapulmonary metastasis…

Protein identified as possible universal therapeutic target for many infections, including Ebola

By using a drug combination of the clinically tested OSU-03012 (AR-12) and FDA approved Phosphodiesterase 5 Inhibitors (Viagra, Cialis) to target GRP78 and related proteins, researchers prevented the replication of a variety of major viruses in infected cells, made antibiotic-resistant bacteria vulnerable to common antibiotics and found evidence that brain cancer stem cells were killed. Data were obtained in multiple brain cancer stem cell types, and using Influenza, Mumps, Measles, Rubella, RSV, CMV, Adenovirus, Coxsakie virus, Chikungunya, Ebola, Hepatitis, E. coli, MRSA, MRSE and N. …

Report on remission in patients with MS three years after stem cell transplant

MS is a degenerative disease and most patients with RRMS who received disease-modifying therapies experience breakthrough disease. Autologous (using a patient’s own cells) hematopoietic cell transplant (HCT) has been studied in MS with the goal of removing disease-causing immune cells and resetting the immune system, according to the study background. The Hematopoietic Cell Transplantation for Relapsing-Remitting Multiple Sclerosis (HALT-MS) study examines the effectiveness of early intervention with HDIT/HCT for patients with RRMS and breakthrough disease. …

Risk for leukemia after treatment for early-stage breast cancer higher than reported — ScienceDaily

The study team reviewed data on 20,063 breast cancer patients treated at eight U.S. cancer centers between 1998 and 2007 whose cancer recurrence and secondary cancer rates were recorded in a database kept by the National Comprehensive Cancer Network. …

Egg and sperm race: Scientists create precursors to human egg and sperm

When an egg cell is fertilised by a sperm, it begins to divide into a cluster of cells known as a blastocyst, the early stage of the embryo. Within this ball of cells, some cells form the inner cell mass – which will develop into the foetus – and some form the outer wall, which becomes the placenta…

This Endoscope Zaps Tumors

It may soon serve another purpose: zapping tumors. The biomedical advancement, which is under development at the University at Buffalo, could make chemotherapy more efficient, reduce its side effects and improve how doctors treat some of the most deadly forms of cancer. “We are developing a novel endoscopic device that will improve our ability to detect and destroy cancer cells,” says Ulas Sunar, PhD, a research assistant professor in UB’s Department of Biomedical Engineering and the principal investigator of a National Institutes of Health grant that supports the research. Conventional endoscopic imaging has limitations. …

Researchers map paths to cancer drug resistance

By mapping the specific steps that cells of melanoma, breast cancer and a blood cancer called myelofibrosis use to become resistant to drugs, the researchers now have much better targets for blocking those pathways and keeping current therapies effective. The findings are published in two papers Dec. 23, 2014, in the journal Science Signaling. “Clinical resistance to anticancer therapies is a major problem,” said lead author Kris Wood, Ph.D., assistant professor of Pharmacology and Cancer Biology at Duke…
