An overview of SELECTTION: Survey of European lung cancer evaluating choice of treatment and tolerability in observed second-line non-small cell lung cancer (NSCLC)
18204 Background: In addition to established second-line treatments for NSCLC in Europe, docetaxel and pemetrexed; erlotinib, has recently been approved. The only study directly comparing alternative options in second-line NSCLC showed no significant difference in efficacy between docetaxel and pemetrexed (median survival 7.9 vs 8.3 months, p = 0.226) but significant differences in toxicity profile (Hanna et al, 2004). It is of interest to observe how different second-line treatment options are used in real life settings, particularly length of therapy, reasons for discontinuation and its impact on patient’s outcomes. Methods: In observational studies patients are not assigned to different treatments at random and physicians and patients decide on treatment. A careful design is paramount to ensure the correct interpretation of data obtained. SELECTTION is the first observational, non-interventional, prospective study to be carried out in Europe in second-line NSCLC treatment. The primary objective of SELECTTION is to assess the time from treatment initiation to treatment discontinuation. Secondary objectives are to observe the reasons for treatment discontinuation and assess its impact on patient’s outcomes. A total of 13 countries will participate including: France, Portugal, Germany, Denmark, and UK with approximately 200 sites enrolling 950 patients. Information regarding patients and disease characteristics and treatment history are collected. Patients may be enrolled if they have received first-line chemotherapy for locally advanced or metastatic NSCLC, and have subsequently progressed, are at least 18 years old and are about to initiate second line treatment. Treatment cohorts will be constructed based on the distribution of patients across second-line treatments by physician decision. Results: At this stage details about design and analyses planned as well as evolution of the study, will be presented. Conclusions: SELECTTION will provide a unique set of data on how patients with stage IIIb\/IV NSCLC previously treated with chemotherapy, are treated in routine clinical practice.
