2. Cellular Adoptive Immunotherapy
Also called adoptive cell transfer, the experimental technique aims to improve the ability of a patient’s natural T-cells (lymphocytes for immunity) to fight cancer, according to the National Cancer Institute. Doctors can take the best and most active T-cells that have invaded a tumor and extract them to multiply in a lab – the patient’s immune cells are then wiped out and the lab-grown cells are re-infused back to them, it adds.
There are variations of this treatment, and the first use of it targeted metastatic melanoma, which can spread quickly through the body. Modified T-cells are also being looked at to treat other solid tumors as well as hematologic cancers (cancers of the blood), it adds.
