What Makes Targeted Therapy Unique?
Targeted therapy is a big step forward in fighting lung cancer. It focuses on the cancer’s specific genetic changes. Treatment plans are made based on the tumor’s genetic information, found in biomarkers. This method stops the cancer cells from growing and spreading, leading to better results.
Mechanism of Action
These therapies work by blocking cancer cell growth paths. For instance, tyrosine kinase inhibitors stop cells from dividing. Angiogenesis inhibitors prevent tumors from getting the blood supply they need. Unique mechanisms of targeted therapy mean less damage to healthy cells and better effectiveness, making it key for personalized cancer treatment.
Differentiation from Chemotherapy
Targeted therapy and chemotherapy are very different. Chemotherapy hits all fast-dividing cells, causing side effects like hair loss and nausea. But, targeted therapies only go after cancer cells. This usually means fewer bad side effects and a better treatment experience. People on targeted therapy often feel better than those on chemotherapy.
To find out who should get targeted therapy, biomarker testing is vital. Many lung cancer patients can get better with these customized treatments, especially if their tumors have specific genetic changes. Targeted therapies focus on these changes, offering new hope in treating lung cancer.
Types of Targeted Therapy Approaches
Learning about targeted therapy for lung cancer is key to finding the right treatment. These therapies focus on certain body processes. They aim to treat cancer effectively and with fewer side effects than chemotherapy.
Tyrosine Kinase Inhibitors
Tyrosine kinase inhibitors, or TKIs, are important in lung cancer treatment. They stop signals that make cancer cells grow and live. TKIs reduce tumor size and slow down the cancer. Drugs like afatinib and erlotinib are taken as pills.
Antibody-Drug Conjugates
Antibody-drug conjugates, or ADCs, mix chemotherapy with targeted delivery. They attach chemo drugs to antibodies that find cancer cells. This targets cancer cells directly and spares healthy ones. This approach makes chemotherapy more effective and limits its side effects.
Angiogenesis Inhibitors
Angiogenesis inhibitors block blood flow to tumors. They target proteins to stop tumors from getting what they need to grow. Drugs like bevacizumab and ramucirumab are used. They help stop tumor growth by cutting off their blood supply.
Targeted Therapy for Lung Cancer: Biomarker Testing
For lung cancer treatment, biomarker testing is crucial. It helps pick the right therapy by looking at tumor genetics. Knowing specific biomarkers helps doctors choose targeted therapies. This leads to better patient outcomes.
The Importance of Biomarker Testing
Biomarker testing is key to finding out who will benefit from targeted treatments. It spots certain genes that matter a lot for treatment success. People with these genes do better with targeted therapy than standard chemo, studies say.
How Biomarker Testing is Conducted
Advanced methods, like next-generation sequencing (NGS), are used for biomarker testing. NGS looks at many biomarkers at once, getting a full picture for each patient. This way, doctors can find the best treatment, leading to better results. For more on detecting lung cancer early and personal assessments, visit personalized lung cancer risk assessments.
