Current treatment for some forms of cancer does not work as well as researchers had initially hoped. But a new virus-based treatment has shown promising results.
New research suggests that the common cold virus can help scientists devise the next treatment for a widespread form of bladder cancer.
Using viruses to treat cancer has long been of interest to medical researchers. One type of virus in particular — oncolytic viruses — can kill tumor cells.
But so far, the Food and Drug Administration (FDA) has only approved one of these: a genetically modified form of herpes to treat melanoma.
The reason that viruses can target tumors is pretty simple. Cancerous tumors are invisible to the immune system, allowing them to grow and spread.
But when a virus enters a cancerous cell and replicates itself, this allows the cancer to be seen, prompting the immune system to treat the disease as it would a common cold.
Melanoma is not the only type of cancer that viruses can affect. Researchers have recently tested a similar treatment on brain tumors.
A new study has found promising results in a form of bladder cancer.
Researchers, many of whom are from the University of Surrey, in the United Kingdom, have investigated the impact of a strain of the common cold virus on non-muscle invasive bladder cancer (NMIBC). Their findings appear in the journal Clinical Cancer Research.
