This is a single arm phase II clinical trial, which aims to evaluate the effectiveness of intercalated combination of doublet chemotherapy of paclitaxel plus carboplatin and erlotinib on patients with advanced stage non-small-cell lung cancer with low abundant activating EGFR mutation.
Name: Intercalated combination of chemotherapy and erlotinib
Description: Primary therapy stage: Paclitaxel Patients receive six cycles of Paclitaxel (175 mg/m² on days 1 of a 4 week cycle, intravenously) plus carboplatin (AUC=5, intravenously on day 1 of a 4 week cycle, intravenously) with sequential erlotinib (150 mg/day) on days 8-21 of each cycle. Maintenance therapy stage: Patients, who complete 6 cycles of therapy without progression or intolerable toxicity, receive erlotinib (150 mg/day) as maintenance therapy until progression, intolerable toxicity or death.Type: Drugchemotherapy and erlotinib
Description: From start of anti-cancer therapy untill progression or death
Measure: Progression free survival defined by imagery methods Time: 8 weeksDescription: From start of anti-cancer therapy till progression of death
Measure: Toxicities related to anti-cancer therapy Time: 8 weeksSingle Group Assignment
There is one SNP
Low abundant activating EGFR mutation: EGFR exon 19 deletion or exon 21 L858R, which are positive by real-time PCR methods and negative by standard sequencing methods. --- L858R ---
