The fact sheet on lung cancer KRAS mutation by Lung Foundation Australia provides detailed information on the KRAS mutation and its implications for lung cancer treatment.
What is a Mutation? A mutation is a change in the DNA sequence of an organism. These changes can occur due to errors during DNA replication, exposure to mutagens, or viral infections. Mutations can be inherited or acquired and can affect how cells function, potentially leading to diseases like cancer.
What are Biomarkers? Biomarkers are measurable traits found in blood, body fluids, or tissues that indicate normal or abnormal processes in the body. They can help diagnose conditions, monitor disease progression, predict treatment responses, and assess overall health. In cancer, biomarkers can include proteins, genes, or other molecules produced by tumors.
KRAS Explained: KRAS is a gene that produces a protein involved in cell signaling pathways that control cell growth and division. Mutations in the KRAS gene can cause the protein to be constantly active, leading to uncontrolled cell growth and cancer. KRAS mutations are common in several cancers, including lung, colorectal, and pancreatic cancers.
Implications for Lung Cancer Treatment: The presence of a KRAS mutation in lung cancer can influence treatment decisions. Targeted therapies that specifically inhibit the activity of the mutated KRAS protein are being developed and tested in clinical trials. These therapies aim to block the signals that drive cancer cell growth and survival. However, KRAS mutations have historically been challenging to target, and research is ongoing to find effective treatments.
Current Treatment Options: For patients with KRAS-mutant lung cancer, treatment options may include standard chemotherapy, immunotherapy, and participation in clinical trials for new targeted therapies. Immunotherapy, which enhances the body’s immune response against cancer cells, has shown promise in some patients with KRAS mutations.
Challenges and Research: One of the main challenges in treating KRAS-mutant lung cancer is the development of resistance to targeted therapies. Cancer cells can adapt and find alternative pathways to continue growing. Ongoing research aims to overcome these challenges by identifying combination therapies and new drug targets.
