Symptom Burden in Extensive Disease Small Cell Lung Cancer (ED-SCLC): A prospective, observational study in U.S. community practices.

Abstract

196 Background: 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 scores reflecting better quality and ranges from 0 to 1.0 (index) or 0 – 100 (VAS). LCSS and EQ-5D values at 60 days were predicted in a repeated measures model for patients having a score at baseline and at least 1 follow-up. Results: The mean LCSS and EQ-5D scores at the start of each line of therapy and predicted 60 day change are presented in the table . 60-day improvement was observed only for appetite and cough in 1L. A slight declining trend was seen in 2L and 3L. Conclusions: Patients with ED-SCLC treated in the community reported a high symptom burden at the start of each line of therapy which did not diminish throughout 60 days of treatment.
