P1.06-041 - Overall Survival and Intermediate Outcomes among Scandinavian Non-Small Cell Lung Cancer Patients: The SCAN-LEAF Study (ID 5141)
14:30 - 15:45 | Author(s): P. Klint
- Abstract
Background:
The past decade has seen several advances in the field of non-small cell lung cancer (NSCLC), with improved tools for tumor characterization as well as novel targeted and immune therapies. It is important to understand the current treatment landscape including treatment outcomes, in order to maximize patient benefits from these advances. SCAN-LEAF is a Scandinavian retrospective cohort study with prospective annual data cuts, providing a unique opportunity for insights into real-world clinical NSCLC practice over more than a decade. It includes clinical practice patterns of tissue biopsy, pathological diagnosis and tumor biomarker status testing, and their relationship to treatment choices and outcomes. Here, we present intermediate and survival outcomes by disease stage and histology subtype, and factors associated with survival.
Methods:
SCAN-LEAF consists of a registry-based cohort including all diagnosed NSCLC patients in Denmark, Norway and Sweden (Cohort 1), and a Swedish sub-cohort (Cohort 2) supplemented with data from electronic medical records (EMRs). Based on the first data collection including data from NSCLC patients diagnosed 2005-2013, overall survival (OS; Cohort 1 & 2) and progression-free survival (PFS; Cohort 2) will be estimated using Kaplan-Meier analysis and reported as cumulative incidences (with 95% CI) by disease stage at diagnosis, histological subtype, biomarker status, presence of metastases, age and gender. Response rates (Cohort 2) will be described by treatment line in addition to stage and histology subtype. Association of stage with survival (Cohort 1 & 2) and treatment response (Cohort 2) will be analyzed by Cox regression with time to event (death or response) as outcome variable and disease stage category at diagnosis, follow-up time, and therapy line as stratification variables. In addition, the relationship between OS and intermediate outcomes, as well as predictors of OS (e.g. smoking and biomarker status, lesion location, metastasis at diagnosis), will be explored by Cox regression (Cohort 2).
Results:
Intermediate and survival outcomes for Scandinavian NSCLC patients diagnosed between 2005 and 2013, as well as any association between overall survival and factors such as patient characteristics and treatment patterns, will be presented.
Conclusion:
The SCAN-LEAF study, expected to include >115,000 Scandinavian NSCLC patients and >2,000 sub-cohort patients diagnosed between 2005 and 2018 during the full duration of the study, will give valuable insights into current care, changing treatment patterns and patient outcomes in a real-world setting. A better understanding of factors associated with survival and intermediate outcomes among NSCLC patients will inform clinical decision-making.
