      Background
      The SCOT registry is an international, multicenter, observational registry of newly diagnosed patients with SCLC. The treatment plan remained the responsibility of the patient’s physician and data collected in this registry reflect a "real world" approach for the diagnosis and treatment of patients with SCLC.

      Methods
      56 centers included 507 evaluable patients between 10[th] of November 2009 to 18[th] of August 2010. Participating countries are from Western Europe, Eastern Europe and Korea. Data has been entered into an electronic CRF via the internet.

      Results
      Mean age was 65.4 years, 73% of the patients were male, mean BMI was 25.5 Kg/m2. Smoking status showed 50% were current and 46% former smokers. The most common symptoms at presentation (>25%) were cough, dyspnea, weight loss and fatigue. Patients presented with an ECOG status of 0 (24%; 33% for limited disease (LD) and 19% for extensive disease (ED)), ECOG 1 (52%), ECOG 2 (19%) and ECOG 3 (5%). Histology was small cell carcinoma in 98% of patients and 66% presented with extensive disease. Chemotherapy alone was given to 59% of patients in the first 6 months of treatment. 58% of patients had one line of therapy, 26% had 2 lines, 11% had 3 lines of therapy and 4% had 4 lines or more. The agents most commonly used in each line of therapy are below: Table 1: Chemotherapy agents by line of therapy in SCOT (% within the treatments of the line)

      AGENT/LINE FIRST SECOND THIRD > 3
      Platinum/Etoposide 90.7 26.8 14.5 10.5
      Topotecan 0.2 25.7 20.2 2.3
      Taxanes 2.1 9.3 21.7 26.3
      Cyclophosphamide 3.9 10.9 11.6 15.8
      Cyclo/Vincristine 3.9 12.0 11.6 15.8
      Vinorelbine 0.2 1.1 2.9 2.3
      Gemcitabine 0.0 2.2 0.0 6.8
      67 % of patients with LD received chemo + thoracic radiotherapy. PCI in the first 6 months was given in 26% of patients (LD 34% ED 22%). Best overall response at 6 months in patients with combined chemoradiotherapy was PR=51%, CR=22%, SD=16%, PD=11%. Median overall survival (OS) was 10.6 months [95%CI 9.6, 12.1] with 17.8mo for limited disease and 8.7mo for extended disease. Western Europe and Korea showed OS of 11.5mo and 11.3mo respectively whereas in Eastern European median OS was 9.1 months.

      Conclusion
      This observational study captured real world data of the current treatment paradigm of SCLC. Patients are commonly treated with etoposide/platinum or chemoradiotherapy as first line. The combination of platinum and etoposide remains by far the first choice of chemotherapy in 1[st] line and often at relapse, followed by topotecan starting from second line and beyond. Details on patterns of disease, treatment and efficacy by region and smoking status plus medical resource utilisation will be available at the meeting.
