Non-small-cell Lung Cancer

Worldwide, lung cancer is the leading cause of cancer mortality in males

and the second-leading cause in females1

~85% of lung cancers are of NSCLC histology2

Most NSCLC cases (>75%) are diagnosed in late stages of disease (stage III

or IV)3

5-year survival rates are <15% across all stages of disease4
