[h=1]A genetically-engineered virus tested in 30 terminally-ill liver cancer patients significantly prolonged their lives, killing tumours and inhibiting the growth of new ones, scientists reported on Sunday.

A patient undergoes a scanner as radiology technicians look at the exam on a screen, on February 6, 2013, at a medical unit specialised in cancer treatment in France. A genetically-engineered virus tested in 30 terminally-ill liver cancer patients significantly prolonged their lives, killing tumours and inhibiting the growth of new ones, scientists reported on Sunday.

Sixteen patients given a high dose of the therapy survived for 14.1 months on average, compared to 6.7 months for the 14 who got the low dose.

"For the first time in medical history we have shown that a genetically-engineered virus can improve survival of cancer patients," study co-author David Kirn told AFP.

The four-week trial with the vaccine Pexa-Vec or JX-594, reported in the journal Nature Medicine, may hold promise for the treatment of advanced solid tumours.

What is the fate of the viruses after they have destroyed the cancer cells?
 
I am worried on the side effects
 
What is the fate of the viruses after they have destroyed the cancer cells?
my guess wanakuwa inactive. since wako engineered to attack cancer cells only then they will have no effect on normal tissue. this type of treatment is not new ingawa its the 1st time wametumika against cancer
