Targeted Chemotherapy – Precision Medicine for Improved Outcomes
Targeted chemotherapy focuses on molecular pathways and proteins unique to cancer cells, sparing normal tissues and reducing side effects. Unlike traditional chemotherapy, which attacks all rapidly dividing cells, targeted therapies aim at specific markers, such as HER2, EGFR, or VEGF receptors.
Drugs include tyrosine kinase inhibitors, monoclonal antibodies, and antibody-drug conjugates, often used in combination with conventional chemotherapy.
Personalized medicine approaches use genetic profiling and biomarker testing to identify patients likely to respond to specific agents. Targeted chemotherapy can be more effective and better tolerated than non-specific cytotoxic drugs. It is commonly used in breast cancer, lung cancer, colorectal cancer, and hematologic malignancies. Real-time monitoring with imaging and lab tests ensures optimal dosing and timely adjustments. Targeted chemotherapy exemplifies the shift toward precision oncology, emphasizing efficacy and safety.
FAQ:Q1: What is the advantage of targeted chemotherapy?A1: It selectively attacks cancer cells, reducing side effects and improving treatment outcomes.Q2: How is therapy personalized?A2: Through genetic profiling and biomarker testing to select the most effective agents.
