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. …

Breast reconstruction using patient’s own tissues yield higher satisfaction rates — ScienceDaily

But the findings may at least partly reflect differences in the characteristics of women choosing different options for breast reconstruction, according to the study by plastic surgeon Dr. Yassir Eltahir and colleagues of University Medical Center Groningen, the Netherlands. Higher Satisfaction Score with Autologous Breast Reconstruction The researchers used the recently developed “BREAST-Q” questionnaire to analyze patient satisfaction and quality of life after breast reconstruction. …

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 — ScienceDaily

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…

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…

‘Sugar-coated’ microcapsule eliminates toxic punch of experimental anti-cancer drug

“We developed 3BrPA to target a hallmark of cancer cells, namely their increased dependency on glucose compared with normal cells. But the nonencapsulated drug is toxic to healthy tissues and inactivated as it navigates through the blood, so finding a way to encapsulate the drug and protect normal tissues extends its promise in many cancers as it homes in on tumor cells,” says Jean-Francois Geschwind, M.D., chief of the Division of Interventional Radiology at Johns Hopkins Medicine. …

Mechanics of cells’ long-range communication modeled by researchers

By developing mathematical models of how the collagen matrix that connects cells in tissue stiffens, the researchers are providing insights into the pathology of fibrosis, cirrhosis of the liver and certain cancers. Tissue stiffness has long been know to be clinically relevant in these diseases, but the underlying changes that alter the mechanics of tissues are poorly understood…

Armed virus shows promise as treatment for pancreatic cancer

The study, funded by the UK charity Pancreatic Cancer Research Fund, investigated whether the effectiveness of the Vaccinia oncolytic virus — a virus modified to selectively infect and kill cancer cells — as a treatment for pancreatic cancer, would be improved by arming it with a gene which modulates the body’s immune system. Despite laboratory studies which show that they can both kill cancer cells and provide immunity against cancer regrowth, oncolytic viruses have not performed well in clinical trials, as the immune system naturally attacks the virus before it can be effective…
