Cancer immunotherapy drug "less toxic and prolongs life"

Cancer immunotherapy drug

PanARMENIAN.Net - An immunotherapy drug that could save some cancer patients from the ordeal of extreme chemotherapy may also help them live longer, researchers say, according to the BBC.

In a trial, pembrolizumab kept head and neck cancers at bay for an average of two years - five times longer than under chemotherapy.

The patients also suffered far fewer side-effects.

Cases of head and neck cancers are rising in the UK and most are diagnosed late, when they are hard to treat.

Immunotherapyis a treatment that does not kill cancer cells itself but instead stimulates the body's immune system to attack them.

Pembrolizumab is already being used to treat a wide range of advanced cancers, including melanoma - a type of skin cancer that spreads easily.

Experts believe the drug has the potential to treat many more.
