Cancer ResearchImmune Aging May Matter More Than Birthdays for Cancer Immunotherapy
Age alone does not reliably predict whether cancer immunotherapy will work. This review examines how aging changes immune defenses and how tumors exploit those changes. It highlights weakened cancer-fighting cells, persistent inflammation, and a reduced ability to recognize threats. The authors discuss whether blood tests and tumor samples could reveal immune aging more accurately than a patient's chronological age, while warning that no single marker captures the whole picture. They also evaluate experimental approaches to support or rejuvenate immunity, including drugs that target senescent cells and treatments that alter cell metabolism. The practical message is to build clinical trials around measured immune function, not birthdays alone. These approaches need prospective validation before routine cancer care. This summary is based only on the abstract, which provides no numerical treatment results.
