Unlocking Personalized Treatment for a Healthier Tomorrow
Targeted therapy is an important part of modern precision medicine. It uses information about cancer's molecular and genetic characteristics to help identify treatments designed to act on specific targets.
What Is Targeted Therapy?
Targeted therapy is a form of medical treatment that focuses on specific molecular features involved in the growth or spread of a disease. In cancer care, these targets can include particular proteins, genes, or other molecular changes found in cancer cells.
Unlike treatments that affect many rapidly dividing cells, targeted medicines are designed to act on specific biological pathways or characteristics. This does not mean that healthy cells are completely unaffected, and targeted therapies can still cause side effects.
Targeted therapy is an important component of precision medicine, where treatment decisions are informed by the biological characteristics of an individual's cancer.
How Does Targeted Therapy Work?
Targeted treatment generally begins with understanding the biological characteristics of the cancer and then determining whether a suitable treatment target exists.
Genetic & Molecular Profiling
Testing may examine genes, proteins, or other molecular features of a tumor to identify changes that could influence treatment.
Identify a Target
The care team determines whether a specific molecular alteration or biological pathway can be targeted by an available treatment.
Select Treatment
When an appropriate target is identified, doctors consider medicines supported by clinical evidence for that specific cancer and target.
Monitor & Adapt
Treatment response and side effects are monitored, and the care plan may be adjusted according to the patient's clinical situation.
What Can Targeted Treatments Focus On?
Different targeted medicines act on different biological features. The exact target depends on the cancer and the molecular findings identified through appropriate testing.
Cancer-Driving Proteins
Some cancers depend on abnormal proteins or signaling pathways that promote growth. Certain medicines are designed to interfere with these pathways.
Gene Alterations
Specific genetic changes can sometimes create vulnerabilities that may be addressed with an appropriate targeted treatment.
Growth Signaling
Some therapies interfere with signals that cancer cells use to grow, divide, or survive.
Tumor Blood Supply
Certain treatments can interfere with pathways involved in the formation of blood vessels that support tumor growth.
Cell Survival Pathways
Some targeted medicines interfere with molecular pathways that help cancer cells survive or multiply.
Specific Biomarkers
Biomarker information can help doctors determine whether a particular targeted treatment may be relevant to an individual's cancer.
How Targeted Therapy Has Changed Cancer Treatment
Targeted medicines have created new treatment possibilities for cancers with specific molecular characteristics.
More Specific Treatment Strategies
Targeted medicines are designed around particular biological features rather than treating every cancer in exactly the same way.
Personalized Care
Molecular information can help doctors select treatment options that are relevant to the characteristics of a patient's cancer.
Different Side-Effect Profiles
Targeted medicines may have different side effects from traditional chemotherapy, although they are not free from treatment-related risks.
New Options for Selected Cancers
Targeted therapies have expanded treatment choices for certain cancers where actionable molecular changes can be identified.
Expanding Applications of Precision Medicine
Targeted and precision-based approaches are also being studied across other areas of medicine. Their use varies according to the disease and available evidence.
Cardiovascular Diseases
Researchers are investigating genetic and molecular factors involved in cardiovascular disease to develop more individualized approaches to prevention and treatment.
Neurological Disorders
Molecular and genetic research is helping scientists investigate potential precision approaches for neurological conditions.
Rare Genetic Diseases
For selected rare disorders, therapies may be developed to address specific genetic abnormalities or their biological consequences.
Treatment Designed Around Your Cancer
Targeted therapy is not simply selected because a treatment is considered "advanced." Doctors first determine whether the patient's cancer contains a target for which an appropriate therapy exists.
The diagnosis and extent of disease help determine which treatment strategies are appropriate.
Testing can help identify genetic or molecular characteristics that may influence treatment selection.
Previous treatment and response can influence the next steps in an individual's cancer care plan.
General health, other medical conditions, possible interactions, and treatment risks are considered.
What Patients Should Know
Toward a More Personalized Future
As research advances and our understanding of genetics and cancer biology improves, precision medicine continues to evolve. Targeted therapy is one part of this broader movement toward more individualized healthcare.
