Fast Acting Virus Kills Melanoma Cancer Cells Before Immune System Can Stop It

Melanoma killer has been highly efficient attacking human cancer cells in animals, lab tests, while ignoring healthy ones

April 23, 2013 - Researchers from Yale University School of Medicine have demonstrated that vesicular stomatitis virus (VSV) is highly competent at finding, infecting, and killing human melanoma cells, both in vitro and in animal models, while having little propensity to infect non-cancerous cells.

"If it works as well in humans, this could confer a substantial benefit on patients afflicted with this deadly disease," says Anthony van den Pol, a researcher on the study. The research was published online ahead of print in the Journal of Virology.

Most normal cells resist virus infection by activating antiviral processes that protect nearby cells.

"The working hypothesis was that since many cancer cells show a deficient ability to withstand virus infection, maybe a fast-acting virus such as VSV would be able to infect and kill cancer cells before the virus was eliminated by the immune system," says van den Pol.

And indeed, the virus was able to selectively infect multiple deadly human melanomas that had been implanted in a mouse model, yet showed little infectivity towards normal mouse cells, he says.

Many different mechanisms are involved in innate immunity, the type of immunity that combats viral infection. van den Pol plans to investigate which specific mechanisms are malfunctioning in cancer cells, knowledge that would be hugely beneficial both in understanding how cancer affects immunity, and in enhancing a virus' ability to target cancer cells, he says.

Melanoma is the most deadly skin cancer. Most melanomas are incurable once they have metastasized into the body. The incidence of melanoma has tripled over the last three decades, and it accounts for approximately 75 percent of skin cancer-related deaths.

About 76,250 men and women (44,250 men and 32,000 women) were expected to be diagnosed with this cancer and 9,180 men and women were expected to die of melanoma of the skin in 2012.

From 2005-2009, the median age at diagnosis for melanoma of the skin was 61 years of age.

Formal publication of this study is scheduled for the June 2013 issue of the Journal of Virology.

Journal of Virology is a publication of the American Society for Microbiology (ASM). The ASM is the largest single life science society, composed of over 39,000 scientists and health professionals. Its mission is to advance the microbiological sciences as a vehicle for understanding life processes and to apply and communicate this knowledge for the improvement of health and environmental and economic well-being worldwide.

About Melanoma

Melanoma is a form of cancer that begins in melanocytes (cells that make the pigment melanin). It may begin in a mole (skin melanoma), but can also begin in other pigmented tissues, such as in the eye or in the intestines.

About 76,250 men and women (44,250 men and 32,000 women) were expected to be diagnosed with and 9,180 men and women to die of melanoma of the skin in 2012.

From 2005-2009, the median age at diagnosis for melanoma of the skin was 61 years of age.

Approximately 0.6% were diagnosed under age 20; 6.8% between 20 and 34; 10.7% between 35 and 44; 18.2% between 45 and 54; 21.6% between 55 and 64; 18.8% between 65 and 74; 16.7% between 75 and 84; and 6.6% 85+ years of age.

The age-adjusted incidence rate was 21.0 per 100,000 men and women per year.

US Mortality

From 2005-2009, the median age at death for melanoma of the skin was 68 years of age. Approximately 0.1% died under age 20; 2.6% between 20 and 34; 5.6% between 35 and 44; 13.5% between 45 and 54; 19.9% between 55 and 64; 21.2% between 65 and 74; 24.1% between 75 and 84; and 12.9% 85+ years of age.

The age-adjusted death rate was 2.7 per 100,000 men and women per year. These rates are based on patients who died in 2005-2009 in the US.

Lifetime Risk

Based on rates from 2007-2009, 1.99% of men and women born today will be diagnosed with melanoma of the skin at some time during their lifetime. This number can also be expressed as 1 in 50 men and women will be diagnosed with melanoma of the skin during their lifetime. These statistics are called the lifetime risk of developing cancer.

Sometimes it is more useful to look at the probability of developing melanoma of the skin between two age groups. For example, 0.99% of men will develop melanoma of the skin between their 50th and 70th birthdays compared to 0.60% for women

Prevalence

On January 1, 2009, in the United States there were approximately 876,344 men and women alive who had a history of melanoma of the skin - 427,810 men and 448,534 women.
