Two new cost-effective ways to predict prostate cancer
Two new risk indicators for prostate cancer will be unveiled at the 2011 European Multidisciplinary Cancer Congress today (Saturday).

First Phase III trial of an alpha-pharmaceutical
Until recently, options for patients with bone metastases from advanced prostate cancer have been very limited. But now the first Phase III study of an alpha-pharmaceutical in these patients has shown that it can prolong survival significantly, according to research reported today (Saturday) at the 2011 European Multidisciplinary Cancer Congress.
Infusing chemotherapy into the liver gives extra months of disease-free life in melanoma patients
Melanoma of the eye (ocular or uveal melanoma) frequently spreads to the liver and, once this has happened, there is no effective treatment and patients die within an average of two to four months. Only about one in ten patients live for a year. Now, final results from a phase III study have demonstrated that a new treatment significantly extends the time patients can live without the disease progressing.
Japan finds radiation in rice, more tests planned

Phase II study shows new cancer drug combination significantly delays breast cancer progression
The first randomised trial to investigate the use of trastuzumab emtansine (T-DM1) – an antibody-guided drug – for the initial treatment of HER2- (human epidermal growth factor receptor-2) positive metastatic breast cancer has shown that it makes a significant difference to the time women live without their disease worsening.
Radiotherapy between or during chemotherapy cycles reduces risk of breast cancer recurrence
Stockholm, Sweden: A major UK trial has produced firm evidence that giving radiotherapy between or during chemotherapy cycles to women with early breast cancer significantly reduces the risk of the cancer recurring in the breast or chest wall. The treatment, known as synchronous chemoradiation, has minimal adverse side-effects and no detrimental effect on the patients' quality of life.
New diagnostic imaging for lung cancer could prevent unnecessary surgery
A new type of diagnostic imaging - which can better differentiate benign lung lesions from those which are cancerous - could be used to prevent unnecessary surgery by enabling more accurate diagnosis of the disease.
Breast cancer tumor make-up changes through the course of disease
New research has found that breast cancer tumours change their hormonal status throughout the course of disease, whereas the decision about the most effective treatment for the patient is usually only based on one biopsy of the primary tumour. For some patients, biopsy verifications of any relapse will be very important because it may completely change their clinical management, a Swedish researcher will tell the 2011 European Multidisciplinary Cancer Congress today (Monday 26 September). Dr. Linda Lindström, from the Karolinska Institutet Department of Oncology-Pathology, Solna, Stockholm, will say that her group's research is the first sizeable study to look at changes in tumours in multiple relapses in breast cancer patients.
Aromatase inhibitor letrozole guards against breast cancer relapse for up to 8 years
Stockholm, Sweden: Results from the longest-running trial comparing tamoxifen with the aromatase inhibitor letrozole show unequivocally that letrozole has withstood the test of time and continues to prevent breast cancer recurrences and reduce the risk of death in post-menopausal women with hormone receptor-positive early breast cancer.

Zoledronic acid reduces the recurrence of breast cancer in post-menopausal women
A trial investigating the use of zoledronic acid to aid chemotherapy for breast cancer has found a significant benefit for post-menopausal women, according to results presented at the 2011 European Multidisciplinary Cancer Congress today. Researchers think it could be the key for a greater understanding of the mechanisms of breast cancer recurrence as well as offering new options for patient care.
Bone-strengthening drug gives pain relief in prostate cancer bone metastases
Stockholm, Sweden: Many prostate cancer patients develop bone metastases, and controlling the pain these cause can be difficult. Now the first large randomised Phase III trial of a bisphosphonate drug in these patients has shown that a single dose of the drug is as good for pain relief as single dose radiotherapy, the standard treatment for bone metastases. Results of the trial were presented today at the 2011 European Multidisciplinary Cancer Congress.
Discovery helps explain why chemo causes drop in platelet numbers
Scientists at the Walter and Eliza Hall Institute have identified a way that chemotherapy causes platelet numbers to drop, answering in the process a decade-old question about the formation of platelets, tiny cells that allow blood to clot.

Belly fat, known clinically as central obesity, has been linked to the development of asthma in a new study.
Foam injections for varicose veins better for patients and cheaper, study finds
Foam injections to treat varicose veins cause less pain for patients and could save NHS money compared with a popular alternative treatment, according to researchers at Imperial College London. The study found that foam therapy was over four times more cost-effective than laser treatment and allowed patients to resume normal activity sooner. The findings were presented today at the annual meeting of the European Vascular Society in Athens.
Couples counseling improves sexual intimacy after prostate treatment
Prostate cancer survivors and their partners experience improved sexual satisfaction and function after couples counseling, according to research at The University of Texas MD Anderson Cancer Center. The article, published in the September issue of Cancer, a journal of the American Cancer Society, revealed both Internet-based sexual counseling and traditional sex therapy are equally effective in improving sexual outcomes. Couples on a waiting list for counseling did not improve.

Scientists at Case Western Reserve University School of Medicine found a way to rapidly produce pure populations of cells that grow into the protective myelin coating on nerves in mice. Their process opens a door to research and potential treatments for multiple sclerosis, cerebral palsy and other demyelinating diseases afflicting millions of people worldwide.
Rogue receptor opens door for rare kidney disease
Effects of a particularly devastating human kidney disease may be blunted by making a certain cellular protein receptor much less receptive, according to new research by scientists from North Carolina State University and a number of French universities and hospitals.

Deep brain stimulation studies show how brain buys time for tough choices
Take your time. Hold your horses. Sleep on it. When people must decide between arguably equal choices, they need time to deliberate. In the case of people undergoing deep brain stimulation (DBS) for Parkinson's disease, that process sometimes doesn't kick in, leading to impulsive behavior. New research into why that happens has led scientists to a detailed explanation of how the brain devotes time to reflect on tough choices.

Jumping gene enabled key step in corn domestication
Corn split off from its closest relative teosinte, a wild Mexican grass, about 10,000 years ago thanks to the breeding efforts of early Mexican farmers. Today it's hard to tell that the two plants were ever close kin: Corn plants stand tall, on a single sturdy stalk, and produce a handful of large, kernel-filled ears. By contrast, teosinte is branchy and bushy, with scores of thumb-sized "ears," each containing only a dozen or so hard-shelled kernels.
Invasion of genomic parasites triggered modern mammalian pregnancy
Genetic parasites invaded the mammalian genome more than 100 million years ago and dramatically changed the way mammals reproduce -- transforming the uterus in the ancestors of humans and other mammals from the production of eggs to a nurturing home for developing young, a new Yale University study has found.
