Around 1,600 people are diagnosed with lung cancer every year, making it one of the most common cancers in Singapore. It is also one of the leading causes of cancer-related deaths locally.1

Lung cancer refers to tumors originating in the lung parenchyma or within the bronchi.1 Non-small-cell lung cancer (NSCLC) is the most common type of lung cancer, making up approximately 85% of lung cancers, and is defined as any type of epithelial lung cancer other than small cell lung cancer (SCLC).2,3
NSCLC can be further subdivided on the basis of histological features into several categories, the most common of which are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.4 Large cell carcinoma has been defined in the past as a tumor that lacks morphologic evidence of either glandular or squamous differentiation.5 Figure 1 shows some of the more common histological subtypes of tumors found in NSCLC.3
