Immunotherapies have been hailed as a major game changer in cancer treatment. But recent research suggests that these treatments may not be as effective as we thought. A new study, published in the journal Nature Immunology, has found that some of the most widely used immunotherapies may not work as expected for certain cancers.

The study looked at a type of immunotherapy known as checkpoint inhibitors, which work by blocking the signals that tumors use to hide from the immune system. While the therapy has had some success in treating certain types of cancer, the researchers found that it may not be as effective as expected for others. The team found that the therapy was much less effective in treating tumors with certain genetic mutations, which could explain why some patients have had poor responses to the treatment. These results could help guide clinicians in determining which patients are likely to benefit from these treatments.
