Abstract

Introduction

Lung cancer is the most common cause of cancer related deaths worldwide¹. Even with advances in chemotherapy and surgical therapy, the overall 5-year survival in lung cancer remains dismal at 12% to 16%². At present lung cancer therapy is in the path of a revolution toward personalised therapy. In the past decade, multiple advances have been made in understanding the underlying biology and molecular mechanism of lung cancer, especially adenocarcinoma. With the arrival of targeted therapy there has been significantly improved outcome in metastatic lung malignancy.

There are 2 broad categories of lung cancer- Small Cell Lung Cancer (SCLC) and Non-Small Cell Lung Cancer (NSCLC). Non-small cell lung cancer consists mainly of adenocarcinoma (38.5%), squamous cell carcinoma (20%) and large cell carcinoma. In the past several decades adenocarcinoma has replaced squamous cell carcinoma as the most prevalent histopathological type.
