Lung cancer is the leading cause of cancer death in both men and women. The majority of patients with lung cancer have non-small cell type (NSCLC). The current standard of care for treating select stage IIIB and stage IV NSCLC is a doublet chemotherapy regimen, such as cisplatin plus gemcitabine, carboplatin plus paclitaxel, or a platinum agent plus vinorelbine. All of these regimens have comparable response rates as first-line therapy. In addition, the combination of cisplatin plus pemetrexed has recently been approved for non-squamous histology, based on results of a large randomized prospective trial in advanced stage NSCLC. Alternative doublet therapy for first-line treatment of NSCLC per ASCO and NCCN guidelines also include a non-platinum doublet or single agent therapy.
