    Abstract

    Background: Small cell lung cancer (SCLC) is associated with poor prognosis due to its early metastatic potential and lack of improved outcomes with newer cytotoxic agents. Identifying factors associated with clinical outcomes can help clinicians determine which patients are more likely to benefit from therapy. Functional Assessment of Cancer Therapy (FACT) subscales and Eastern Cooperative Oncology Group performance status (ECOG PS) were retrospectively analyzed as prognostic factors for overall survival (OS) and progression-free survival (PFS) in patients with extensive-stage disease (ED)-SCLC. Methods: Using data from a Phase III trial of pemetrexed-carboplatin vs. etoposide-carboplatin, the effect of the prognostic factors on OS and PFS was analyzed via Cox models. The Kaplan-Meier method was used to estimate OS and PFS parameters for the prognostic subgroups (defined by baseline FACT scores and ECOG PS). Results: Patients with higher baseline FACT-General (FACT-G) score (≥median) had significantly higher OS (hazard ratio [HR] = 0.62, P
