Breaking Down Immunotherapy: A New Approach to Fight Cancer
Treatment Strategies: Investigators Discover Methods to Forecast Results of Immune Therapy
Hey there! Let's chat about the latest in cancer treatments – immunotherapy. This innovative approach leverages your body's immune system to combat disease.
Cancer cells usually develop mutations that enable them to hide from the immune system. Immunotherapy gives your immune system a boost, making it more effective at spotting and destroying cancer cells. While it's a promising treatment option for cancers such as breast cancer, melanoma, leukemia, and non-small cell lung cancer, it doesn't work for everyone or every type of cancer.
That's where Johns Hopkins University comes in, shedding some light on this mystery. Their researchers have discovered a specific set of mutations within cancer tumors, which they call "persistent mutations," that indicate a tumor's susceptibility to immunotherapy. These mutations make the cancer cells more visible to the immune system, leading to a better response to the treatment.
So, how do these findings affect cancer patients? In the near future, doctors might be able to use advanced sequencing techniques to study a patient's mutational spectrum and categorize them based on their likelihood of responding to immunotherapy. Over time, these prognostic indicators may even become predictive factors that help doctors tailor treatment to each individual patient.
Now, let's get a bit technical. These persistent mutations render cancer cells continuously visible to the immune system, causing an ongoing immune response. This response is further amplified by popular immunotherapy agents like immune checkpoint blockade antibodies. Other therapies like CAR-T cell therapy, vaccines, and even radiation therapy may also play a role.
In this groundbreaking study, the researchers identified key biomarkers that indicate a tumor's receptivity to immunotherapy. They include Mismatch Repair Deficiency (dMMR), High Microsatellite Instability (MSI-H), and High Tumor Mutational Burden (TMB-H). These biomarkers are already approved for patient selection for immune checkpoint inhibitor (ICI) therapy, as they denote a higher likelihood of response to immunotherapy.
