Coffee consumption reduces risk of liver cancer, analysis suggests

"Our research confirms past claims that coffee is good for your health, and particularly the liver," said Carlo La Vecchia, MD, study author from the department of epidemiology, Istituto di Ricerche Farmacologiche "Mario Negri," and department of clinical sciences and community health, Università degli Studi di Milan, Italy. "The favorable effect of coffee on liver cancer might be mediated by coffee’s proven prevention of diabetes, a known risk factor for the disease, or for its beneficial effects on cirrhosis and liver enzymes." Researchers performed a meta-analysis of articles published from 1996 through September 2012, ultimately studying 16 high-quality studies and a total of 3,153 cases. This research fills an important gap as the last meta-analysis was published in 2007, and since then there has been data published on more than 900 cases of HCC…

Cancer cells’ communication path blocked

The Lund University research team has looked at how cancer cells communicate with surrounding cells and how this encourages the development of malignant tumours. The idea is to try and inhibit tumours by disrupting this communication. The focus of their research is ‘exosomes’, small virus-like particles that serve as ‘transport packages’ for genetic material and proteins transmitted between cells. …

Physical activity may reduce risk of esophageal cancer

In a meta-analysis of four studies, Dr. Singh and his colleagues observed a 32 percent lower risk of esophageal adenocarcinoma, which can arise from Barrett’s esophagus, in people who were physically active. The meta-analysis also showed the overall risk of esophageal cancer was 19 percent lower among the most physically active people, compared with the least physically active. "Obesity has been associated with increased risk of esophageal cancer through high levels of insulin, as well as chronic inflammation. …

Multivitamins with minerals may protect older women with invasive breast cancer

"Our study offers tentative but intriguing evidence that multivitamin/mineral supplements may help older women who develop invasive breast cancer survive their disease," said Sylvia Wassertheil-Smoller, Ph.D., lead author of the study and distinguished university professor emerita of epidemiology and population health at Albert Einstein College of Medicine of Yeshiva University. Multivitamin/mineral supplements are the most commonly consumed dietary supplements among U.S. adults. They usually contain 20-30 vitamins and minerals, often at levels of 100 percent of U.S…

Biomarker, potential targeted therapy for pancreatic cancer discovered

These findings, being published in the Oct. 4, 2013, online edition of PLOS ONE, also show that the use of a biotherapy consisting of a lysosomal protein, known as saposin C (SapC), and a phospholipid, known as dioleoylphosphatidylserine (DOPS), can be combined into tiny cavities, or nanovesicles, to target and kill pancreatic cancer cells…

Estimate of amount of radiotherapy dose wasted in compensating for tumour growth between treatments

In research to be presented to the 2013 European Cancer Congress (ECC2013), Professor John Yarnold will say that, until now, there has been contradictory evidence as to whether gaps between radiotherapy treatments, for instance overnight or at weekends, makes any difference to the overall effectiveness of radiotherapy on breast cancer, and, if it does make a difference, why that could be. "Traditionally, breast cancer has not been regarded as a fast growing cancer, unlike some other cancer types, but our research now suggests that a significant part of the daily radiotherapy curative dose is ‘used up’ in compensating for tumour growth overnight and over weekends. We have estimated that the amount of radiotherapy dose that is used up in this way corresponds to approximately 0.60 Gray (Gy) per day," says Prof Yarnold, who is Professor of Clinical Oncology at The Institute of Cancer Research, London, and Honorary Consultant at the Royal Marsden NHS Foundation Trust (London, UK). "This is the first numerical estimate to suggest that the duration of a course of radiotherapy has an effect on local cancer cure for patients with early breast cancer…

Critical gaps discovered in breast cancer research

It is estimated that around 570,000 people are living with, or after, a diagnosis of breast cancer in the UK, and this number is expected to double by 2030. Breast cancer, therefore, remains a significant challenge. Over 100 specialist breast cancer scientists, clinicians and heath care professionals reviewed a wide range of issues and challenges involved in breast cancer research, prevention and treatment. Through facilitated discussions and consultation, including appraisal from experts and patients, they produced an account outlining ten major gaps and five strategic solutions. …

Biomarker predicts long-term risk of breast cancer recurrence

"We have validated a unique ‘fingerprint’ in the primary tumor of breast cancer patients that can help identify a high or low risk of cancer recurrence," says study co-author Paul Goss, MD, PhD, director of the Breast Cancer Research Program at Massachusetts General Hospital (MGH) Cancer Center. "This should enable us to offer prolonged treatment to patients who remain at risk and, importantly, to avoid the costs and side effects of treatment in those at low risk." Standard treatment for early-stage, ER-positive breast cancer includes five years of treatment with either tamoxifen or an aromatase inhibitor, drugs that block the action of estrogen. …
