According to the journal Nature, scientists have made an important step in creating a universal cure for cancer which makes the immune system attack tumors as if they were viruses.
The scientists took pieces of cancer’s genetic RNA code, put them into small nanoparticles of fat and then injected the mixture into the bloodstreams of three patients in the advanced stages of the disease.
Their immune systems responded by producing “killer” T-cells created to attack cancer. The vaccine was found to be very helpful in fighting growing tumors in mice as well, as scientists from the Johannes Gutenberg University in Germany stated.
They added that such vaccines are fast and cheap to produce, and almost any tumor antigen can be encoded by RNA. After a patient with lymph node tumor was given the vaccine, the tumor got smaller. Moreover, another patient who had surgically removed tumors was cancer-free seven months after the vaccination.
The third patient had eight tumors that spread from skin cancer into lung cancer. After the patient was given the vaccine, the tumors remained ‘clinically stable’.
