Could there be a gleevec for brain cancer?

A similar drug might be able to tame some brain cancers, new research from Columbia University Medical Center has shown. A team led by Antonio Iavarone, MD, professor of neurology and of pathology and cell biology, Institute for Cancer Genetics, previously discovered that a fusion of two proteins (present only in cancer cells and different from the two in CML) drives some cases of glioma, a common form of brain cancer. The team’s most recent study, published in Clinical Cancer Research, looked closely at two patients affected by recurrent glioblastoma with the fused proteins, in a first in-human trial of a drug that targets half of the fusion protein. Those patients, the researchers found, responded particularly well to the drug, with clinical improvement and radiological tumor reduction…

An extra protein gives naked mole rats more power to stop cancer

The protein is associated with a cluster of genes (called a locus) that is also found in humans and mice. It’s the job of that locus to encode–or carry the genetic instructions for synthesizing –several cancer-fighting proteins. As Professor of Biology Vera Gorbunova explains, the locus found in naked mole rats encodes a total of four cancer-fighting proteins, while the human and mouse version encodes only three proteins. …

Molecular alterations in head and neck cancers uncovered by study

The researchers also uncovered new smoking-related cancer subtypes and potential new drug targets, and found numerous genomic similarities with other cancer types. Taken together, this study’s findings may provide more detailed explanations of how HPV infection and smoking play roles in head and neck cancer risk and disease development, and offer potential novel diagnostic and treatment directions. The study is the most comprehensive examination to date of genomic alterations in head and neck cancers…

Scientists home in on reasons behind cancer drug trial disappointment

Numerous angiopoietin-blocking therapies, which work to starve the tumour of its blood supply, are currently in clinical trials for ovarian cancer and other cancers. But despite promising earlier results, some of these therapies are not improving patient survival as much as was expected…

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. …

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. …

Lung Cancer: New Genetic Anomalies Discovered

By analyzing the DNA and RNA of lung cancers, researchers at the University of Michigan Comprehensive Cancer Center found that patients whose tumors contained a large number of gene fusions had worse outcomes than patients with fewer gene fusions. Gene fusions are a type of genetic anomaly found in cancers that occurs when genes get rearranged and fuse together. In addition, the researchers identified several new genetic anomalies that occur in lung cancer, including in patients with a history of smoking. …
