New report draws attention to urgent need to tackle disparities in cancer care worldwide

A proposal for a new financing model to tackle the major disparities that exist in the prevention, diagnosis, treatment and outcome of cancer in countries worldwide has been presented at the 2013 European Cancer Congress (ECCO 2013). While much progress has been made against cancer over the last century, a new report brings together evidence that not every patient benefits from it, nor even has the opportunity to benefit. The economics of cancer are daunting and the current model of financing is broken, said Professor Peter Boyle, President of the International Prevention Research Institute (Lyon, France) and Director of the Institute of Global Public Health of the University of Strathclyde (Glasgow, United Kingdom and Lyon, France) in a presentation entitled 'The State of Oncology'.

RAS mutations predict a lack of response in patients with metastatic colorectal cancer who receive panitumumab–FOLFOX4

Patients with metastatic colorectal cancer and KRAS mutations in exon 2 do not benefit from anti-EGFR therapy. However, other activating RAS mutations may predict poorer outcome with anti-EGFR therapy. In a prospectively planned retrospective biomarker analysis from the PRIME study, reported in The New England Journal of Medicine by Dr Jean-Yves Douillard of Institut René Gauducheau, who is currently a Chair of the ESMO Educational Committee, and colleagues, the addition of panitumumab to FOLFOX4 regimen was associated with improved progression-free survival and overall survival in patients without RAS mutations.

Gene test shows promise for identifying aggressive prostate cancer

Researchers from Columbia University have identified 3 genes they used to predict whether prostate cancer in men with low-risk disease would stay low-risk, or become more of a threat. The researchers analyzed prostate biopsy specimens from 43 men who were followed for at least 10 years through active surveillance (with no immediate treatment). All the men had been diagnosed with low-risk prostate cancer, but in 14 of them the cancer eventually started to grow or become more aggressive. All 14 were correctly identified by the gene test.

Researchers look for ways to reduce side-effects of cancer therapy on kids

A University of Calgary researcher is part of a national project trying to determine if genetic variations make some children more susceptible to the harmful side-effects of medications including Cisplatin. About half of all adverse reactions are thought to be caused by genetic differences. “Pinpointing a genetic basis for adverse reactions to some of these medications would equip physicians with important information,” says Dr. David Johnson, the pediatrician leading the Calgary arm of the project. “Screening tests could one day tell us which children are more likely to experience harmful side-effects, and doctors could then adjust dosages or try different medications or treatment,” he says.

Interrupting cancer cell “conversation”: A new way to put the brakes on cancer

While great strides have been achieved in cancer treatment, scientists are looking for the next generation of therapeutics to stop the second-leading cause of death nationwide. A new approach to disrupt the “conversation” between cancer cells that promote tumor growth has been developed through a collaborative effort linking chemists at NYU and pharmacologists at USC.

In a study appearing the week of September 9 in the Proceedings of the National Academy of Sciences, the research groups of Bogdan Olenyuk of the USC School of Pharmacy and Paramjit Arora of the NYU College of Arts and Sciences explain their development of a synthetic molecule, the “protein domain mimetic” — representing an emerging frontier in cancer research that is distinct from the typical search for small molecules that target cancer cells.

Rather, this synthetic molecule targets the interaction between two proteins, at the point where intracellular signaling converges resulting in up-regulation of genes that promote tumor progression.

This compound was specifically designed to interrupt the type of molecular conversation within the cell — called cell signaling — that promotes growth of cancer cells and tumor progression. Read more here.

Dutch study shows that radiation therapy for ductal carcinoma in situ does not seem to increase cardiovascular disease risk

A large population-based study in the Netherlands found that women who had received radiation therapy to treat ductal carcinoma in situ of the breast (DCIS) have no increased risk of cardiovascular disease compared to the general population of Dutch women, nor compared to DCIS patients treated with surgery only. These results may be helpful to women who are deciding on their treatment plan and seem reassuring for DCIS survivors treated with radiotherapy. This is the first large study to evaluate long-term effects of radiotherapy for DCIS on both the incidence of cardiovascular disease and associated death rates. Read more here.

Seven potential immunotherapy targets for treatment of melanoma identified

NCI scientists, using a unique digital technology that counts RNA molecules in small amounts of tumor tissue, identified seven potential immunotherapy targets for treatment of melanoma. Immunotherapy works by boosting the body’s immune system, or by using immune cells to attack specific types of cancer cells. The success of this treatment for melanoma, and all forms of cancer, is contingent upon finding protein targets that are overexpressed, or highly active, on cancerous tumor cells, but have limited expression in normal tissue. The seven gene targets identified in this work meet these criteria. The results of this study, headed by Richard A. Morgan, Ph.D., Surgery Branch, Tumor Immunology Section, Center for Cancer Research at NCI, appeared Sept. 10, 2013, in Clinical Cancer Research. Read more here.
