Types of Lung Cancer Biomarkers
It’s important to know about lung cancer biomarkers. They help doctors treat patients better. There are two main types: driver mutations and immunotherapy biomarkers.
Driver Mutations
Driver mutations are changes in genes that help lung cancer grow. Some key mutations are:
- EGFR mutations
- ALK rearrangements
- KRAS mutations
- BRAF V600E mutation
- NTRK fusion
About 30% of non-small cell lung cancer patients have KRAS mutations. Around 10% of adenocarcinoma cases show EGFR mutations. Finding these mutations is key. Targeted therapies can block the pathways these mutations activate. This offers personalized treatment plans.
Comprehensive biomarker testing is mainly used for non-small cell lung cancer. It identifies specific mutations that help cancer cells grow.
Immunotherapy Biomarkers
Immunotherapy biomarkers show how lung cancer hides from the immune system. The PD-L1 biomarker is really important. It checks if the tumor can avoid the immune system. Knowing about these biomarkers helps doctors choose the best treatment.
Precision medicine uses these markers to pick treatments that are more likely to work. This improves how well treatments work.
Understanding driver mutations and immunotherapy biomarkers leads to better treatment plans. This can help increase survival rates. For more details on these treatments, visit this resource.
Comprehensive Biomarker Testing Process
The journey of comprehensive biomarker testing starts by tailoring initial recommendations to the patient’s health status and their specific kind of lung cancer. In the case of non-small cell lung cancer (NSCLC), it’s often advised to do extensive molecular profiling. This helps find specific genetic changes that could guide the choice of treatment.
Initial Testing Recommendations
At first, tests mainly look for well-known biomarkers like EGFR and ALK. These are linked with big improvements in health. More than 80% of NSCLC patients are tested for these mutations. This highlights how vital they are in making treatment choices.
For example, testing for the ROS1 marker is done in 88% of cases. Meanwhile, PD-L1 is checked in 57% of advanced nonsquamous NSCLC patients. Knowing these details helps doctors pick targeted therapy or immunotherapy. These options can increase survival rates compared to standard treatments.
Liquid vs. Tissue Biopsies
When it comes to types of testing, choosing between liquid and tissue biopsies is important. Tissue biopsies give clear results. They allow for precise genetic profiling in lung cancer. But liquid biopsies are becoming popular as they’re less invasive.
This is especially true for patients who can’t have surgery. Studies show that liquid biopsies match tissue tests 68% of the time. This highlights their growing role in medicine. Each testing method has its own pros and cons. It’s key that patients and doctors know what each entails.
