Efficacy of Erlotinib in Neoadjuvant Setting in Patients With Stage IIIA, N2-positive Non-Small Cell Lung Cancer

A Phase II Trial of Neoadjuvant Erlotinib (Tarceva®) Followed by Surgery for Selected Patients With Stage IIIA, N2-positive Non-Small Cell Lung Cancer

This study propose neoadjuvant chemotherapeutic role by erlotinib.

It is widely accepted that patients with locally advanced non-small cell lung cancer would have better outcome with neoadjuvant therapy followed by surgery than surgery alone. However what should be the standard treatment option is still unclear.

Erlotinib (Tarceva®)is an oral inhibitor of epidermal growth factor receptor (EGFR) tyrosine kinase and its anti-neoplastic effect is approved especially women, patients with adenocarcinoma, non-smoker and Asian population. Moreover if the malignant tissue has EGFR mutation, its efficacy is known to be enhanced.

So we expect that in those population, patients with locally advanced, N2 positive, erlotinib would be more beneficial than conventional cytotoxic chemotherapy in safety and convenience as neoadjuvant therapy.
