Let’s say the pathologist is behind the film, in front of the microscope in the lab, not the patient in the hospital with a tumor.
While many patients may not follow an individual, no specialist is more important than ensuring that a single cancer treatment provides an effective approach.
Over the years, the pathologist’s keen eye and deep understanding of tumors have been a valuable source of information. But today, pathologists also have access to genomic information, making their work more important than ever. As we gain an understanding of how certain genetic mutations affect response and treatment, pathologists must become more adept at defining genetic variation when they diagnose cancers and rare types.

Now, with innovations such as targeted treatment and immunotherapy, genomes are more important than ever for understanding cancer. This article will be a continuation of the focus on the annual meeting of the American College of Pathologists (CBT), particularly on ring replacement therapy and cancer treatment.
Several markers have been identified that may be associated with response and treatment. For example, the expression level of PD-L1 is currently being tested in several clinical trials as a marker to help predict response to immunotherapy in immunotherapy.1 But this marker has not been achieved. There are several different types of tests, each with a well-defined PD-L1.2 specification. Of course, psychologists may disagree with the best test. Furthermore, PD-L1 is expressed rapidly in many cell types, including immune cells and cancer cells.3 Taken together, these factors contribute to PD-L1 dependence as predicted by biometrics.

Tumor mutation obesity (TMB) has recently emerged as a numerical marker that can help predict the likelihood of immunotherapy response in many cancers, including melanoma, lung cancer, and colon cancer.4,5,6 TMB is defined as the total frequency of movement. per genomic tumor area code. Importantly, TMB continues to grow. This provides several options that can be used to guide better treatment decisions, such as targeted screening or immunotherapy or enrollment in clinical trials.
TMB is now included in the FoundationOne® Comprehensive Genome Profile Test (CGP). In contrast to the hotspot assay, the FoundationOne® Experiment used a large number of similar DNA sequences to modify the secret code of more than 300 genes now known as strong tumors. The complete design of the test also provides a useful option for molecular testing. This requires only a small sample of tissue (slides 8-10) that can be taken from a previous biopsy and still provide results in both cancer-type and genome-specific models.
The addition of TMB to the FoundationOne test is a significant breakthrough in our ability to adapt to the evolving science of immunotherapy. By adding this clinical label that has a long-term relationship with treatment response.4,5,6 FoundationOne can help doctors unlock the full potential of the right drug for cancer treatment.
