Immune Response Predictions: Scientists uncover methods for anticipating therapy outcomes
In the ever-evolving battle against cancer, scientists strive to uncover new treatments that can offer a glimmer of hope. One such cutting-edge approach is immunotherapy, leveraging the body's own immune system to eradicate malignant cells. However, not every person or cancer responds favorably to this treatment option, leading researchers in constant pursuit of answers.
Recently, scientists from Johns Hopkins University in Maryland have made a remarkable discovery. They've found a specific subset of mutations within a cancer tumor that indicates how receptive it may be to immunotherapy. This groundbreaking research, published in the journal Nature Medicine, could revolutionize the way doctors select patients for immunotherapy and predict its outcomes.
Immunotherapy harnesses the power of the immune system to fight cancer. Typically, cancer cells develop mutations that enable them to evade detection. Immunotherapy offers a boost to the immune system, making it easier for it to find and destroy these devious cells. There are various types of immunotherapy, including checkpoint inhibitors and CAR-T cell therapy, to name a few.
As of now, immunotherapy is being used to treat breast cancer, melanoma, leukemia, and non-small cell lung cancer. Researchers are also exploring its potential in treating other cancers such as prostate cancer, brain cancer, and ovarian cancer.
Intriguingly, the researchers found a subset of mutations within the overall tumor mutation burden (TMB) that remain constant, or what they call "persistent mutations." These mutations keep cancer cells visible to the immune system, prompting a better response to immunotherapy. This subset of mutations, it appears, offers a more accurate method for determining a tumor's receptiveness to immunotherapy compared to overall TMB.
"Persistent mutations may help clinicians more accurately select patients for clinical trials of novel immunotherapies or predict a patient's clinical outcome with standard-of-care immune checkpoint blockade," Dr. Valsamo Anagnostou, a senior author of the study and an associate professor of oncology at Johns Hopkins, explained.
While the search results do not specifically mention this particular subset of mutations identified by Johns Hopkins University, it's worth noting that studies often find certain genetic mutations and alterations can influence a tumor's response to immunotherapy. For instance, tumors with a higher TMB are typically more responsive to immunotherapy. Additionally, mutations affecting the major histocompatibility complex (MHC) like HLA-II can impact a tumor's immunopeptidome and microenvironment, potentially affecting its receptiveness to immunotherapy.
The future looks promising for cancer patients as advanced sequencing techniques could categorize patients based on their likelihood of response to immunotherapy or benefit from other treatments. Over time, these prognostic indicators may evolve to become predictive factors that can interact with therapy and disease.
