Erlotinib Versus Pemetrexed as Second-Line Therapy in Treating Patients With Advanced Lung Adenocarcinoma
Both pemetrexed and erlotinib are second-line treatment options for patients with advanced non-small cell lung cancer. It is controversial that whether it is necessary to detect epidermal growth factor receptor (EGFR) mutation status for the EGFR-targeted therapy after the failure of standard chemotherapy. The role of EGFR gene copy number as a predictive marker remains controversial. Therefore, we investigate the efficacy of erlotinib and pemetrexed as second-line therapy in treating in patients with EGFR wild-type and EGFR FISH-positive advanced lung adenocarcinoma.

- Progression-Free Survival [ Time Frame: 1 year after the last patient is randomized ] [ Designated as safety issue: No ]Progression-free survival was defined as the time from the date of randomization to the date of tumour progression or death from any cause.
- Best Tumor Response [ Time Frame: While receiving study treatment; assessed every 6 weeks until progression ] [ Designated as safety issue: No ]Tumor responses were evaluated according to Response Evaluation Criteria In Solid Tumors (RECIST).
- Overall Survival [ Time Frame: 1 year after the last patient is randomized ] [ Designated as safety issue: No ]Overall survival was defined as the time from the date of randomization to the date of death from any cause

Standard first-line treatment for advanced-stage non-small cell lung cancer (NSCLC) usually consists of platinum-based doublet chemotherapy, but progression ultimately occurs for most patients. Second-line treatment options available to patients who suffer failure of first-line treatment include further chemotherapy (docetaxel and pemetrexed) or targeted therapy. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) show great efficacy in patients with advanced NSCLC with EGFR mutation. High EGFR gene copy number was associated with great sensitivity and prolonged progression-free survival of NSCLC from EGFR-TKIs. This phase II study was designed to assess the efficacy and safety of erlotinib compared with pemetrexed as second-line treatment for EGFR wild-type and EGFR FISH-positive lung adenocarcinoma.
