Both esophageal cancer and stomach cancer are aggressive malignancies with contrasting risk factors, histologies, and molecular characteristics-yet for the most part comparable therapeutic approaches.

Esophagogastric Junction and Gastric Adenocarcinoma: Current Challenges and Future Directions 

The epidermal growth factor receptor (EGFR) promotes the growth of different cell types and has been implicated in tumorigenesis. The EGFR comprises a family of four structurally similar tyrosine kinases with a complex link to downstream signaling molecules that ultimately regulate key cell processes. Anti-EGFR agents have been developed as promising therapeutic anticancer targets, and some have been recently approved for the treatment of non-small-cell lung cancer and colon cancer. The two anti-EGFR therapies with the greatest clinical application are monoclonal antibodies that block the binding of ligands to EGFR and small-molecule tyrosine kinase inhibitors that inhibit the binding of adenosine triphosphate to the internal tyrosine kinase receptor of EGFR. We attempt to give an overview of the EGFR function and biology, focusing on the most important clinical findings and applications of EGFR inhibitors in lung and head and neck cancer.

Targeting the Epidermal Growth Factor Receptor

Recent advances in molecularclassification and the adventof noncytotoxic molecularlytargeted therapies have offered increasedhope of improving the diagnosis,treatment, and prognosis forpatients with non–small-cell lung cancer(NSCLC).[1] Yet the use of chemotherapyin NSCLC has continuedto evolve over recent years with theappearance of newer cytotoxic agentsthat have improved the outcome forpatients. Doublet combination chemotherapyhas become the standardof care for patients with advanceddisease and good performance status.Prolongation of survival has also beenshown with second-line chemotherapyfor patients whose tumors are refractoryto first-line agents.[1]
