Immunotherapy Outcomes Prediction: Scientists Discover Strategies for Estimating Responses
Fighting Cancer with Immunotherapy: A Closer Look at Responsive Tumors
In the ever-evolving battle against cancer, immunotherapy is one of the latest weapons in our arsenal. But not every cancer or patient responds to immunotherapy treatment. That's where the scientists at Johns Hopkins University come in.
The researchers have made a promising discovery - a specific subset of mutations in cancer tumors that hints at how receptive the tumor will be to this treatment. This breakthrough could pave the way for more accurate patient selection and better treatment outcomes.
The findings of this groundbreaking study were recently published in the journal Nature Medicine.
What is Immunotherapy?
Immunotherapy leverages the body's immune system to combat disease. Normally, cancer cells evade the immune system by developing mutations that allow them to hide. Immunotherapy gives the body's defense system a boost, empowering it to find and destroy these hidden cancer cells.
There are different types of immunotherapy, including checkpoint inhibitors, CAR T-cell therapy, and vaccine therapy.
The Power of Persistent Mutations
Currently, doctors use the total number of mutations in a tumor, known as tumor mutation burden (TMB), to gauge its responsiveness to immunotherapy. But according to the researchers, a large number of mutations doesn't always guarantee a good response.
In this study, the researchers identified a specific subset of mutations within the overall TMB, which they called "persistent mutations." These mutations are less likely to disappear as cancer evolves, ensuring that the cancer remains visible to the immune system and prone to a better response to immunotherapy.
"Persistent mutations render the cancer cells continuously visible to the immune system, eliciting an ongoing immune response," explained Dr. Valsamo Anagnostou, a senior author of the study. "This response is accentuated in the context of immune checkpoint blockade, leading to sustained immune control over the cancer cells and resulting in long survival."
Paving the Way for Personalized Immunotherapy
By analyzing persistent mutations, doctors can more accurately select patients for immunotherapy and better predict treatment outcomes. By doing this, it may become possible to move beyond mere prognostic indicators and towards predictive factors that can interact with therapy, disease, and even the immune tumor environment.
In the future, high-throughput, next-generation sequencing techniques may be used to examine a patient's mutational spectrum, helping to categorize patients by their likelihood of response to immunotherapy. Ultimately, this knowledge could help in the personalization of immunotherapy, improving outcomes for cancer patients everywhere.
