I didn’t say immuno oncology is a new thought, I said treating cancer like an infection and creating therapies that target specific cancer is a newish thought. Your immune system remembers and targets infection with very high specificity, that is not true for cancer. Most cancer therapies over the decades have been either broad acting chemotherapies or drugs to increase tumor penetrating T cells (think pd-1 and the like). Training the immune system on specific cancers (personalized cancer therapy) like described in the article is new. These therapies are known as Car-T, dendritic cell therapies (what this article is about), as well as newer NK cell therapies. Dendritic cel therapy(cancer vaccines) require you to take a tumor biopsy, sequence the antigen, train the dendritic cell taken from the patient in a lab on that antigen/s, ensure antigen expression, and then replant the dendritic cells into the patient. That is innovative as it imitates the immune systems response to infection. Source: I worked in immune oncology for years…
