This approach to treatment focuses on specific genetic and molecular alterations within cancerous cells in the colon and rectum. For instance, if a tumor exhibits a particular genetic mutation known to drive its growth, medications designed to block the activity of that mutated gene product can be administered. This contrasts with traditional chemotherapy, which affects all rapidly dividing cells, including healthy ones.
The precision of these treatments often leads to improved outcomes for patients, including higher response rates, longer progression-free survival, and reduced side effects compared to conventional chemotherapies. Historically, colorectal cancer treatment relied heavily on surgery, radiation, and broad-spectrum chemotherapy. The advent of this personalized medicine strategy represents a significant advancement, offering new hope and improved quality of life for individuals facing this diagnosis.
