Non-invasive advanced image analysis could lead to better patient care

July 2, 2014 3:40 pm | News | Comments

Obtaining evidence of genetic changes to make a cancer diagnosis usually requires a biopsy, which can be problematic for sensitive regions of the body such as the lungs. Based on recent review of patients with lung cancer, researchers have found that scanning the tumor cells with quantitative computed tomography based texture analysis (QTA) determines (with 90% accuracy) whether the patient's tumor had a cancer-causing gene mutation.

Scientists find potential new use for cancer drug

June 27, 2014 7:19 am | News | Comments

Scientists working to make gene therapy a reality have solved a major hurdle: how to bypass a blood stem cell’s natural defenses and efficiently insert disease-fighting genes into the cell’s genome. In a new study, a team of researchers report that the drug rapamycin, which is commonly used to slow cancer growth, enables delivery of a therapeutic dose of genes to blood stem cells while preserving stem cell function.

3-D mammogram scans may find more breast cancer

June 24, 2014 5:22 pm | by Lindsey Tanner - AP Medical Writer - Associated Press | News | Comments

3-D mammograms may be better at finding cancer than regular scans, a large study suggests, although whether that means saving more lives isn't known. The study involved almost half a million breast scans, with more than one-third of them using relatively new 3-D imaging along with conventional scans. The rest used regular mammograms alone.

Delivering drugs on cue

June 24, 2014 7:43 am | News | Comments

Current drug delivery systems used to administer chemotherapy to cancer patients typically release a constant dose of the drug over time, but a new study challenges this "slow and steady" approach and offers a novel way to locally deliver the drugs "on demand," as reported in the Proceedings of the National Academy of Sciences.

Breathalyzer test may detect deadliest cancer

June 18, 2014 4:04 pm | News | Comments

Lung cancer causes more deaths in the U.S. than the next three most common cancers combined, and the main reason is poor detection methods. A new device developed by a team of Israeli, American and British cancer researchers may turn the tide by both accurately detecting lung cancer and identifying its stage of progression. The breathalyzer test is embedded with a "NaNose" nanotech chip to literally "sniff out" cancer tumors.

Nanoshell shields foreign enzymes used to starve cancer cells from immune system

June 17, 2014 11:24 am | News | Comments

Nanoengineers at UC San Diego have developed a nanoshell to protect foreign enzymes used to starve cancer cells as part of chemotherapy. Enzymes are naturally smart machines that are responsible for many complex functions and chemical reactions in biology. However, despite their huge potential, their use in medicine has been limited by the immune system, which is designed to attack foreign intruders.

New study aims to rapidly test lung cancer drugs

June 16, 2014 2:16 pm | by Marilynn Marchione - AP Chief Medical Writer - Associated Press | News | Comments

A bold new way to test cancer drugs started Monday. Like a medical version of speed dating, doctors will sort through multiple experimental drugs and match patients to the one most likely to succeed based on each person's unique tumor gene profile. Five drug companies, the government, private foundations and advocacy groups are taking part.

Antibodies from the desert act as guides to disease cells

June 13, 2014 8:19 am | News | Comments

Researchers have developed nanoparticles that not only bypass the body’s defence system, but also find their way to the diseased cells. The procedure uses fragments from a particular type of antibody that only occurs in camels and llamas. The small particles were even successful under conditions which are very similar to the situation within potential patients’ bodies.

Study: Red meat possibly linked to breast cancer

June 11, 2014 9:22 am | by Maria Cheng - AP Medical Writer - Associated Press | News | Comments

Women who often indulge their cravings for hamburgers, steaks and other red meat may have a slightly higher risk of breast cancer, a new study suggests. Doctors have long warned that a diet loaded with red meat is linked to cancers including those of the colon and pancreas, but there has been less evidence for its role in breast cancer.

Scientists reveal details of calcium “safety valve” in cells

June 9, 2014 8:18 am | by Karen McNulty Walsh, Brookhaven National Laboratory | News | Comments

Sometimes a cell has to die—when it's done with its job or inflicted with injury that could otherwise harm an organism. Conversely, cells that refuse to die when expected can lead to cancer. So scientists interested in fighting cancer have been keenly interested in learning the details of "programmed cell death." They want to understand what happens when this process goes awry and identify new targets for anticancer drugs.

New clues to why older women are more vulnerable to breast cancer

June 6, 2014 10:56 am | by Dan Krotz, Lawrence Berkeley National Laboratory | News | Comments

Scientists from Lawrence Berkeley National Laboratory have gained more insights into why older women are more susceptible to breast cancer. They found that as women age, the cells responsible for maintaining healthy breast tissue stop responding to their immediate surroundings, including mechanical cues that should prompt them to suppress nearby tumors.

Short nanotubes target pancreatic cancer

June 6, 2014 10:45 am | by Mike Williams, Rice Univ. | News | Comments

Short, customized carbon nanotubes have the potential to deliver drugs to pancreatic cancer cells and destroy them from within, according to researchers at Rice Univ. and the Univ. of Texas MD Anderson Cancer Center. Pristine nanotubes produced through a new process developed at Rice can be modified to carry drugs to tumors through gaps in blood-vessel walls that larger particles cannot fit through.

Tech Aids Cancer Research

June 4, 2014 2:32 pm | by Lindsay Hock, Managing Editor | Thermo Fisher Scientific | Articles | Comments

Cancer is a group of diseases characterized by uncontrolled growth and spread of abnormal cells. The disease can be caused by both external and internal factors; and, if the spread isn’t controlled, it can result in death. The annual cancer statistics report from the American Cancer Society estimates there will be 1,885,540 new cancer cases and 585,720 cancer deaths in the U.S. for 2014.
