Symptom Burden In Extensive Disease Small Cell Lung Cancer (Ed-Sclc): A Prospective, Observational Study In Us Community Practices.

196Background: There is a paucity of data describing the effect of treatment on symptom burden and health status for patients with ED-SCLC receiving care in US community oncology centers. This study explores ED-SCLC patient-reported outcomes independently for either first-line (1L), second-line (2L) or third-line (3L) therapy. Methods: CA209-118 is a prospective observational study of adult patients with lung cancer, including patients with ED-SCLC, in 70 US community practices enrolled between 2014-2017. Participants completed the Lung Cancer Symptom Scale (LCSS) and Euro-QoL 5-D (EQ-5D) utility index and visual analog scale (VAS) at the start of 1L, 2L, or 3L treatment and at follow-up visits. The LCSS is summarized in 3 scales: LCSS total scale which ranges from 0 – 100, average symptom burden scale (ASBI) ranging from 0 – 100, and a three-item global scale (3-IGI) ranging from 0 – 300 (lower scores reflect reduced burden). The EQ-5D scale is a preference based measure of health status with higher scor...
