Heparin derivative suppresses neuroblastoma tumor growth
Researchers at Duke Medicine have identified a new strategy for treating neuroblastoma using a modified version of heparin, a century-old injectable drug that thins the blood to prevent clots from forming. The study, conducted in mice and published June 17, 2014, in the Journal of Clinical Investigation, found that when heparin is altered to remove its blood-thinning properties, it can suppress and shrink neuroblastoma tumors without causing severe bleeding.

Outreach doubles colon cancer screening in low-income communities
In low-income and minority communities where colonoscopies may be prohibitively expensive for residents, less-invasive, more frequent testing combined with automated reminders can yield dramatic improvements in colorectal cancer screening rates, a new study reports. Patients who received follow-up mailings, text messages and calls by staff were more than twice as likely to complete an at-home colon cancer screening test.

No long-term anxiety or distress associated with low-dose computed tomography screening
Examination and review of several studies that evaluated patient-centered outcomes for individuals undergoing low-dose computed tomography screening for lung cancer found that screening does not appear to significantly influence overall health-related quality of life or result in long-term changes in anxiety or distress, but that positive results in the short-term, do increase distress levels.

Majority of older breast cancer patients use hormone treatment
Women 65 years of age and older comprise about half of patients with breast cancer. Some studies suggest this group initiates therapy less often and discontinues treatment more frequently than younger or middle aged women. 'We found a more positive picture of use,' says the study author. Only 14 percent of the 65- to 91-year-olds in the study didn't start treatment. Non-white women much more likely to not have therapy.

Lipids help to fight leukemia
T cells use a novel mechanism to fight leukemia. They may recognize unique lipids produced by cancer cells and kill tumor cells expressing these lipid molecules. A study conducted by researchers at the University of Basel shows that a tumor-associated lipid stimulates specific T cells, which efficiently kill leukemia cells both in vitro and in animal models. The results have been published in the Journal of Experimental Medicine.

Specialists who treat prostate cancer agree that active surveillance is an effective option -- yet most don't recommend it when appropriate for their own patients, according to a study in the July issue of Medical Care.

Gene 'switch' reverses cancer in common childhood leukaemia
Melbourne researchers have shown a type of leukaemia can be successfully 'reversed' by coaxing the cancer cells back into normal development. The discovery was made using a model of B-progenitor acute lymphoblastic leukaemia, the most common cancer affecting children. Researchers from the Walter and Eliza Hall Institute showed that switching off a gene called Pax5 could cause cancer in a model of B-ALL, while restoring its function could 'cure' the disease.

Nanoshell shields foreign enzymes used to starve cancer cells from immune system
Nanoengineers at the University of California, San Diego have developed a nanoshell to protect foreign enzymes used to starve cancer cells as part of chemotherapy. Their work is featured on the June 2014 cover of the journal Nano Letters. 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.

How to prevent disparities in colon cancer screening
People living in poverty are less likely to be screened for colorectal cancer -- and more likely to develop the disease and die from it. Mailing a stool test promises to help end these disparities, write Beverly Green, M.D., M.P.H., and Gloria Coronado, Ph.D., of Kaiser Permanente Center for Health Research in JAMA Internal Medicine.

BRCA test results affect patients' breast cancer surgery plans
A new study reports that 7 in 10 women with breast cancer who learned before surgery they have BRCA gene mutations changed their surgical plan, often to a more extensive procedure that would reduce future cancer risk. The authors therefore recommend that women who meet genetic testing guidelines get the tests before surgery.

Low cholesterol linked with worse survival in patients with kidney cancer
People are often told to reduce their cholesterol to improve their heart health, but new research suggests that low cholesterol may increase kidney cancer patients' risk of dying from their disease. The findings, which are published in BJU International, indicate that cholesterol testing may help doctors as they monitor and treat patients with kidney cancer.

Antibodies from the desert as guides to diseased cells
Nanoparticles are considered a promising approach in detecting and fighting tumour cells. The method has, however, often failed because the human immune system recognizes and rejects them before they can fulfil their function. Researchers at Helmholtz-Zentrum Dresden-Rossendorf and at University College Dublin have developed nanoparticles that bypass the body's defence system and find the diseased cells. This procedure uses fragments from an antibody that only occurs in camels and llamas.
