Immuno-oncology
A field of cancer treatment that harnesses or stimulates the patient's own immune system to identify and destroy tumor cells. It encompasses checkpoint inhibitors, CAR-T cell therapies, and cancer vaccines as alternatives or complements to chemotherapy and radiation.
What is immuno-oncology?
Immuno-oncology is a field of cancer treatment that works by enlisting the patient's own immune system to recognize and attack tumor cells, rather than killing them directly with toxic agents or radiation. The central idea is to remove the brakes on immune cells or to arm them so they can find and destroy cancer.
It encompasses several distinct approaches, including checkpoint inhibitors that release immune cells from tumor-imposed restraints, CAR-T cell therapies that re-engineer a patient's own cells, and therapeutic cancer vaccines. These can be used alone or alongside chemotherapy and radiation.
Why is immuno-oncology significant?
Immuno-oncology has reshaped cancer care by producing durable responses in some patients who had few options under traditional therapies. Because it engages the immune system's adaptability, it can sometimes provide long-lasting control of disease.
The field is also a major focus of pharmaceutical research and investment, driving a steady pipeline of new agents and combinations. Understanding immune resistance and patient selection remains central to extending its benefits to more cancer types.
