The Association Between Initial Chemotherapy Treatment Timing, Intensity, And End-Of-Life (Eol) Care Trajectory Among Older Adults With Advanced Stage Lung Cancer (Alc).
JOURNAL OF CLINICAL ONCOLOGY(2020)
Abstract
e24009 Background: The use of chemotherapy regimens with varying intensities at specific time points may have an effect on EOL care trajectories among older adults with aLC (IIIB & IV). Methods: Using the Surveillance, Epidemiology, and End Results (SEER)–Medicare registry and claims data, we selected decedents diagnosed with aLC (small cell: SCLC and non-small cell: NSCLC) between 2008 and 2013 who survived ≥6 months (death between 2008 and 2014). Main outcome measures were EOL care trajectories in the 6 months prior to death among patients receiving chemotherapy characterized by intensity levels. A multinomial logit model was used to determine the association between intensity of initial chemotherapy regimen and EOL care trajectory. Results: Our sample (N = 10,594) was mostly NSCLC (77%) of whom only 63% received chemotherapy. Patients receiving chemotherapy were predominantly males (70.4%), age 66-69 years (80%), non-Hispanic white (68.1%) and 78.4% were married. 41 % received treatment prior to EOL-6 and 10.4 % first initiated treatment during EOL-6. The majority of patients received a platinum-based doublet as a first line therapy. Compared to non-cisplatin platinum doublet chemotherapy, patients receiving cisplatin were least likely to be in the decreasing intensity EOL group and most likely to be in increasing intensity EOL group (see table). Conclusions: Among aLC decedents, patients who received cisplatin chemotherapy as compared to non-cisplatin doublet chemotherapy were least likely to be in the decreasing EOL intensity group and most likely to be in the increasing EOL intensity group. EOL care preferences may need to be considered when choosing initial chemotherapy treatment regimens. [Table: see text]
