Colon cancer prevention and early detection

Over the past few decades, more people have been surviving colon cancer, and fewer people have been dying from it. This is thanks partly to improvements in colon cancer screening. Screening, the process of looking for cancer or pre-cancer in people who have no symptoms of the disease, can find colon cancer early, before symptoms develop, when it’s easier to treat. Screening can also sometimes find growths called polyps so they can be removed before they turn into cancer. Read more here.

Combo of Avastin, second drug shows promise fighting brain cancer, Mayo Clinic finds

The drug bevacizumab, also known by the trade name Avastin, shrinks tumors briefly in patients with an aggressive brain cancer known as glioblastoma multiforme, but then they often grow again and spread throughout the brain for reasons no one previously has understood. Now, Mayo Clinic researchers have found out why this happens. They have also discovered that pairing Avastin with another cancer drug, dasatinib, can stop that lethal spread. Dasatinib is approved for use in several blood cancers. Read more here.

Young Oncologists' Journal Club: Association between treatment effects on disease progression end points and overall survival in clinical studies of patients with metastatic renal cell carcinoma

"Treatment of metastatic renal cell carcinoma (mRCC) was once limited to the treatment with interleukin-2 and interferon (INF)-α. Major efforts in understanding the molecular mechanism of the disease have led to a better understanding of the molecular biology of renal cancer, and this has subsequently led to the development of a multitude of drugs acting on the vascular endothelial growth factor (VEGF) and the mammalian target of rapamycin (mTOR) pathway. The registration of many of these new drugs (sunitinib, sorafenib, axitinib, lapatinib, pazopanib, bevacizumab, everolimus or temsirolimus) has led to the situation where it is increasingly difficult to show improvement of overall survival (OS) with even newer drugs, and to define the best sequence of this various compounds in patients with mRCC."

Effect of passenger mutations

A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for uncontrolled growth of cancers. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression, but a new study from MIT, Harvard University, the Broad Institute and Brigham and Women’s Hospital reveals, shows for the first time, when enough of these so-called passenger mutations accumulate, they can slow or even halt tumour growth.

New legislation on artificial tanning: The Canadian Cancer Society highlights its speedy implementation

“This legislation, which prohibits the sale of artificial tanning services to those under 18 years of age, is a great victory for public health,” says Suzanne Dubois, Executive Director of the CCS – Quebec Division. “The Canadian Cancer Society strongly believes in working to stop preventable cancers even before they occur. In this respect, the legislation is a clear message from the government to the whole population about the risk and danger of artificial tanning.” Read more here.

Ban the tobacco industry’s secret weapon

The federal government banned flavoured cigarettes two years ago. Not long before that, Barack Obama did the same thing south of the border. So why is the Canadian Cancer Society still talking about it? For one thing, loopholes allow the tobacco industry to continue targeting young consumers with an array of other equally dangerous, flavoured tobacco products. And neither ban restricts menthol.

How cancer cells rewire their metabolism to survive

Cancer cells need food to survive and grow. They’re very good at getting it, too, even when nutrients are scarce. Many scientists have tried killing cancer cells by taking away their favorite food, a sugar called glucose. Unfortunately, this treatment approach not only fails to work, it backfires—glucose-starved tumors actually get more aggressive. In a study published in the journal Cell, researchers discovered that a protein called PKCζ is responsible for this paradox. The research suggests that glucose depletion therapies might work against tumors as long as the cancer cells are producing PKCζ. Read more here.

NIH scientists identify molecular link between metabolism and breast cancer

A protein associated with conditions of metabolic imbalance, such as diabetes and obesity, may play a role in the development of aggressive forms of breast cancer, according to new findings by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and their colleagues. Metabolic imbalance is often caused by elevated carbohydrate intake, which can lead to over-activating a molecule called C-terminal binding protein (CtBP). This over-activation, in turn, can increase the risk of breast cancer. Read more here.

Identification of genetic marker for placebo response could influence trial design

Although placebos have played a critical role in medicine and clinical research for more than 70 years, it has been a mystery why these inactive treatments help to alleviate symptoms in some patients and not others. Now researchers have for the first time identified genetic differences between placebo responders and non-responders, providing an important new clue to the placebo effect. Led by investigators at Beth Israel Deaconess Medical Center and Harvard Medical School, the new findings demonstrate that genetic differences that account for variations in the brain's dopamine levels help to determine the extent of a person's placebo response.
