Rationale for the epidermal growth factor receptor as a target for cancer therapy
1Cleveland Clinic Foundation, 9500 Euclid Ave, R-33, Cleveland, OH 44195, USA.
Objectives:
To provide information regarding tumor-specific molecules and signaling pathways responsible for regulation of tumor growth, and review the development of novel targeted therapies that can block the epidermal growth factor receptor (EGFR) at biologically active and less toxic doses compared with standard chemotherapy.
Data Sources:
Research articles.
Conclusions:
The identification and understanding of novel molecular targets has led to the development of therapeutic agents specific to these targets. Clinical investigations involving EGFR inhibitory agents are being completed. Studies have shown single-agent efficacy and efficacy in combination with chemotherapy and/or radiation therapy.
Implications For Nursing Practice:
Nurses are involved in the administration of targeted therapies. They serve to ensure effective patient education, compliance, and early intervention for toxicities. Knowledge regarding the impact of signaling pathways and the goals of targeted therapy will maximize treatment outcomes for cancer patients.
Insights
