"2012 was one heck of a year for new treatments against various different forms of leukemia. In the span of 5 months, the U.S. Food and Drug Administration approved four novel therapies. Drug approvals always come with a spike of media attention, but we at W2O Group have been curious as to how that flood of interest compares with other events throughout the year, not only in news, but in all of the other conversations we have online about cancer. So we decided to look into how we’re talking about cancer, both at the broadest level and in the context of more specific cancers and more specific communities."

H. pylori, smoking trends, and gastric cancer in US men
Trends in Helicobacter pylori (H. pylori) and smoking explain a significant proportion of the decline of intestinal-type noncardia gastric adenocarcinoma (NCGA) incidence in US men between 1978 and 2008, and are estimated to continue to contribute to further declines between 2008 and 2040. These are the conclusions of a study by Jennifer M. Yeh of the Center for Health Decision Science at the Harvard School of Public Health in Boston and colleagues that suggest H. pylori and smoking trends together accounted for almost half of the observed decline in intestinal-type NCGA between 1978 and 2008.

Scheduled imaging studies provide little help detecting relapse of aggressive lymphoma
Imaging scans following treatment for diffuse large B-cell lymphoma do little to help detect a relapse, a Mayo Clinic study has found. The overwhelming majority of patients with this aggressive lymphoma already have symptoms, an abnormal physical exam or an abnormal blood test at the time of relapse, the researchers say. The findings will be presented at the American Society of Clinical Oncology annual meeting May 31-June 4 in Chicago. Read more here.
Despite new recommendations, women in 40s continue to get routine mammograms at same rate

Doctors should discuss financial concerns of cancer patients
Most cancer patients would like to talk about the cost of their care with their doctors, but often don't because they fear the discussion could compromise the quality of their treatment, researchers at Duke Cancer Institute plan to report at the 2013 Annual Meeting of the American Society of Clinical Oncology. Yet many patients who do broach the subject of finances believe it helps decrease costs. Those findings, from a survey of 300 insured patients treated at Duke and affiliated clinics in rural North Carolina, suggest that doctors can play a role in easing financial worries just by taking the problem into account.

American Cancer Society marks 100th year with one goal - to finish the fight against cancer
One hundred years ago today, the American Cancer Society was founded by 15 prominent physicians and business leaders in New York City. First known as the American Society for the Control of Cancer, the organization launched the fight against a disease that was feared as a death sentence at the time. A century later, the American Cancer Society, now the nation's largest voluntary health organization, observes 100 years of progress – this year alone saw a 20 percent decline in cancer death rates since the 1990s according to the Society's latest Cancer Facts & Figures, that translates to more than one million cancer deaths avoided during that span – more birthdays celebrated. The Society is marking the occasion by pledging to finish the fight against cancer in the next century. Read more here.
THALOMID (thalidomide capsules) - Risk of second cancers
THALOMID® is an immunomodulatory agent indicated for the treatment of patients who are 65 years of age or older with previously untreated multiple myeloma, in combination with melphalan and prednisone (MPT). The following points summarize the updated Product Monograph safety information: 1. Second primary malignancies, in particular acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), have been observed in an ongoing clinical trial in patients with previously untreated multiple myeloma receiving the combination melphalan, prednisone and THALOMID® (MPT). AML and MDS have been rarely reported in the post-market setting. 2. The risk of AML and MDS must be taken into account before initiating treatment with THALOMID® in combination with melphalan and prednisone (MPT). Physicians should carefully evaluate patients before and during treatment using standard cancer screening for occurrence of second primary malignancies. Read more here.

Molecular marker from pancreatic 'juices' helps identify pancreatic cancer
Researchers at Mayo Clinic have developed a promising method to
distinguish between pancreatic cancer and chronic pancreatitis — two
disorders that are difficult to tell apart. A molecular marker obtained
from pancreatic "juices" can identify almost all cases of pancreatic
cancer, their study shows. The findings were being presented at
Digestive Disease Week 2013 in Orlando, Fla. Pancreatic cancer and
chronic pancreatitis both produce the same signs of disease in the
pancreas, such as inflammation, but cancer in the organ is a
life-threatening disorder that must be treated immediately and
aggressively. Read more here.

Study IDs key protein for cell death
When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA. A new finding from MIT researchers may offer a way to overcome that resistance: The team has identified a key protein involved in an alternative death pathway known as programmed necrosis. Drugs that mimic the effects of this protein could push cancer cells that are resistant to apoptosis into necrosis instead. Read more here.

Primary care physicians vital to complete care of prostate cancer patients
Androgen deprivation therapy is a common and effective treatment for advanced prostate cancer. However, among other side-effects, it can cause significant bone thinning in men on long-term treatment. A new study¹ by Vahakn Shahinian and Yong-Fang Kuo from the Universities of Michigan and Texas respectively, finds that although bone mineral density testing is carried out on some men receiving this therapy, it is not routine. They did note, however, that men were significantly more likely to be tested when they were being cared for by both a urologist and a primary care physician. Read more here.

Angelina Jolie: My medical choice
"My doctors estimated that I had an 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer, although the risk is different in the case of each woman. Only a fraction of breast cancers result from an inherited gene mutation. Those with a defect in BRCA1 have a 65 percent risk of getting it, on average. Once I knew that this was my reality, I decided to be proactive and to minimize the risk as much I could. I made a decision to have a preventive double mastectomy."

EU funded CAMINEMS project combines three emerging technologies – nanotechnology, optical technologies, and microfluidics
Some 90% of cancer deaths are caused by metastases that are most often caused by circulating tumour cells (CTCs) which escape from the primary tumour. Being able to capture and study CTCs would be of enormous benefit for research, to help understand the cells’ metabolism, how they colonise other organs and how they may respond to either existing or future drugs. Existing technologies, however, are unable to do this. Work is now underway to develop a second-generation, pre-industrial prototype of CTCs device. Read more about the project here.

Can breastfeeding lower breast cancer risk?
"There are a limited number of things that women can do to lower their risk of breast cancer, including getting regular physical activity, limiting alcohol, and maintaining a healthy weight. Breastfeeding has often been included in the protective behaviors against breast cancer, but the research has been inconsistent. Looking at the research on breastfeeding and breast cancer risk, it is clear that this has been a difficult area to study." Continue reading the American Cancer Society Expert Voices blog here.

Cholesterol drugs may boost kidney cancer survival
A new study from the University of Chicago suggests that cholesterol-lowering statin drugs may improve survival of renal cell carcinoma. Statin drugs are known for their anti-inflammatory and self-destruction properties, which may lead to lowering the risk of developing certain types of cancer. According to study author Dr. Scott Eggener, associate professor of urologic oncology at the University of Chicago, "given that one in four Ameicans over 45 years of age take a statin and renal cell carcinoma occurs most often in men ages 50 to 70, it may be prudent to prospectively evaluate if statins protect against cancer progression."
